<p>The Indian Space Research Organisation (ISRO) chairman S Somanath provided a big update on the Chandrayaan-3 mission on Tuesday (August 8) as he assured that Vikram lander will be able to make a soft-landing on the Moon's surface on August 23.&nbsp;</p>

<p>He claimed that the landing is certain even if all the sensors and two of its engines do not work. The Vikram lander is expected to descend on the moon on August 23.</p>

<p>Somnath was speaking during an interaction hosted by the non-profit organisation Disha Bharat, as he said that the design of the lander is such that it would be able to handle failures. The interaction was on the topic — 'Chandrayaan-3: Bharat's Pride Space Mission'.&nbsp;</p>

<p>Somanath said: "If everything fails, if all the sensors fail, nothing works, still it (Vikram) will make a landing. That's how it has been designed -- provided that the propulsion system works well."&nbsp;</p>

<p>The mission was launched on July 14 by the Launch Vehicle Mark-3 rocket. It is now placed in a 170 km by 4,313 km elliptical orbit around the moon and a series of manoeuvres are planned for August 9 and 17 to place it in a 100 km circular orbit.&nbsp;</p>

<p>ISRO chief said on Monday that India's third lunar mission "Chandrayaan-3" is in good health. He said that its most critical phase will be the orbit determination process when the spacecraft starts moving closer to the moon from the 100 km circular orbit.&nbsp;</p>

<p>Somanath told PTI: "Up to 100 km we do not see any difficulty. The issues are only an estimation of the position of the lander accurately from Earth. This measurement is a very critical measurement, we call it the orbit determination process. If it is correct, the rest of the process can be done."&nbsp;</p>

<p>"We are able to bring it down very correctly this time. The orbit changes are happening as planned. There is no deviation. So, it shows excellent results and we are hoping that all will be fine," the ISRO chairman added.&nbsp;</p>

WATCH | ISRO releases video of the moon captured by Chandrayaan-3 as it enters lunar orbit

<p>Having travelled a distance of nearly 3.84 lakh kilometres over a period of 20 days in space, India's third Lunar spacecraft Chandrayaan-3 has been captured by the Lunar gravity. At present, the craft is circling the moon in a highly-elliptical orbit. In a circular orbit, a spacecraft constantly remains at a certain distance from the body that it is orbiting. However, in a highly elliptical orbit, the craft circles the celestial body (moon, in this case) where its distance from the body varies drastically.&nbsp;</p>

<p>“MOX, ISTRAC, this is Chandrayaan-3. I am feeling lunar gravity,” ISRO said on X, formerly known as Twitter, indicating that Chandrayaan-3 is under the moon's gravitational influence. Chandrayaan-3 has been successfully inserted into the lunar orbit, the Indian space agency added. The craft has been captured by Lunar gravity after it performed what is known as a Lunar Orbit Insertion manoeuvre.</p>

<p>"During the Lunar orbit insertion, the craft will reach the vicinity of the moon and within the Lunar gravitational influence. Thereafter, it would fire its on-board engines to slow itself down and get captured into Lunar orbit. Then, it would begin to circle the moon in a highly-elliptical orbit," Dr. Mylswamy Annadurai explained to WION. Having contributed majorly towards India's maiden Lunar mission Chandrayaan-1 as its Project Director, Dr. Annadurai earned the moniker 'Moon Man of India'. He had retired from ISRO as the Director of UR Rao Satellite Centre.</p>

<h2><strong>The journey so far...&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </strong></h2>

<p>Chandrayaan-3 was launched on 14&nbsp;July from India's spaceport, Satish Dhawan Space Centre, Sriharikota. Sixteen minutes from the lift-off, the craft was placed in a highly elliptical orbit around the earth. Thereafter, by performing five engine burns, the craft raised its orbit on five occasions and slingshot itself further away from Earth, while continuing to remain in Earth's orbit.&nbsp;</p>

<p>In the intervening night of 31st July and 1st August, Chandrayaan-3 performed its Trans-Lunar injection burn. This was a long-duration firing of its engines and it pushed the craft out of Earth's gravitational pull and towards Lunar gravitational influence. "By firing its engines for the TLI, the craft gained departure velocity and set course from the earth orbit towards a location in the vicinity of the moon," Dr. Mylswamy Annadurai had told WION.&nbsp;</p>

<h2><strong>The journey ahead...&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</strong></h2>

<p>ISRO has said that the craft's next operation would be the maiden reduction of orbit around the moon. It is scheduled for August 6th 2023, around 23:00hrs IST, ISRO said. Just like ISRO slingshot the craft away from earth by performing multiple engine firings, the same process would be carried out for the reverse effect. Engine firings would be done to bring the craft closer to the lunar surface and eventually into a circular orbit around the moon.&nbsp;</p>

<p>"When the lander separates from the propulsion module, the craft will be in a 100x100kms circular orbit around the moon. The craft would be in that orbit for 4-5 days and we would use that period to test the crucial systems, sensors that would be used for the lunar landing (because, this is the first time we would be testing them in space)." M.Sankaran, Director of ISRO's UR Rao satellite Centre, had told WION.</p>

<p>Thereafter, the craft would be brought to 100x30kms orbit and then a process of Rough braking, Attitude hold, Fine braking, velocity reduction would be carried out, in the run-up to the lunar landing. ISRO has planned the Lunar landing at 5:47 pm Indian Standard Time, on 23rd August.</p>

<h2><strong>Objectives of Chandrayaan-3...&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp;</strong></h2>

<p>India's 3rd Lunar spacecraft comprises a propulsion module, lander and rover. The combined mass of them is 3.9 tonnes. The key goal of the craft is to perform a lunar soft-landing and perform in-situ analysis near 70 degrees latitude of the Lunar surface. The mission is expected to last 14 earth days or one lunar day, during which the six-wheeled rover and the lander will perform their respective experiments.&nbsp;<br />

Chandrayaan-3 successfully inserted into Moon’s orbit, under lunar gravity now: ISRO

<p>A mysterious, cylindrical object that was found on a beach near Jurein Bay in Western Australia is "most likely debris from an expended third-stage of a Polar Satellite Launch Vehicle (PSLV)", the Australian Space Agency announced on Monday, July 31.</p>

<p>The Australian Space Agency(ASA) first mentioned this object on July 17&nbsp;after media reports on the subject sparked&nbsp;speculations about the likely origins of the mysterious object found on the beach.</p>

<p>On social media, enthusiasts initially linked this mysterious object to the missing Malaysian plane MH370, a Boeing 777-200ER aircraft that went missing in the year 2014, with 239 persons on board.</p>

<p>Some even speculated that the object had military origins.</p>

<p>As a coincidence, the news of this debris being spotted along the shores of&nbsp;a small Australian coastal town, came barely days after Australia-based social media users shared photos of India's Chandrayaan-3 upper-stage flight being visible over parts of Australia.</p>

<p>The Chandrayaan-3 flight being visible over parts of Australia was initially speculated as a UFO sighting&nbsp;in that part of the world.&nbsp;</p>

<p>The Chandrayaan-3 mission was launched on India's LVM3 rocket, at 2:35 pm Indian Standard Time on July 14 and the news of the debris spotting came on July 17.</p>

<p>However, the debris had no connection to the Chandrayaan-3 mission or the LVM3 rocket that launched it.&nbsp;</p>

<p>PSLV is an Indian spacefaring rocket that has performed 58 launch missions and had its maiden launch in the year 1993.</p>

<p>The PSLV is a four-stage rocket that is powered by solid and liquid fuels. The first stage is powered by solids, the second by liquids, the third by solids and the fourth by liquids. India uses the PSLV to launch satellites weighing between 500 kgs and 1,750 kgs.&nbsp;</p>

<p>It is the most-flown Indian spacefaring rocket and a highly-reliable one at that.</p>

<p>The PSLV has the unique distinction of lofting most of the 431 foreign-origin satellites that India has put into space, as part of commercial arrangements. The PSLV launched India's maiden Lunar mission Chandrayaan-1 and its only Mars mission, Mangalyaan. Soon, PSLV will also be launching India's maiden mission to study the Sun.&nbsp;</p>

<p>"The debris remains in storage and the Australian Space Agency is working with ISRO, who will provide further confirmation to determine the next steps, including considering obligations under the United Nations space treaties", the ASA tweeted on Monday, 31<sup>st</sup>&nbsp;July.</p>

<p>It also urged its citizens to report to local authorities, if they happen to spot any similar debris.&nbsp;</p>

Explained: How did Indian PSLV rocket debris end up on an Australian beach?

<p>ISRO successfully carried out its second launch mission this month, with the successful orbiting of seven Singaporean satellites using its Polar Satellite Launch Vehicle (PSLV) launcher, this morning (July 30). In a mission that lasted around 25 minutes, the Indian launch vehicle hurled the primary passenger DS-SAR radar-imaging, Earth observation satellite and six co-passenger satellites into the designated orbit.&nbsp;</p>

<p>"We have a very perfect orbit accomplishment," said ISRO Chairman Dr S Somnath.</p>

<p>This PSLV mission marks the successful launch of 431 foreign-origin satellites by the Indian space agency&nbsp;since the year 1999.&nbsp;</p>

<p>D Radhakrishnan, chairman and managing director of NSIL (ISRO's commercial arm) said that it was historic for a single customer (Singapore government and academia) to use the PSLV launcher for four launch missions. Referring to it as a "real record", he expressed faith that Singapore would use the services of ISRO-NSIL for many more missions that they have planned for the coming times.&nbsp;</p>

<p>Notably, it is after a hiatus of nearly five years&nbsp;that ISRO performed two launches in a month. The last time was in November 2018, when ISRO performed launch missions of its LVM3/GSAT-19 and PSLV-HySIS, in quick succession.</p>

ISRO successfully launches seven Singaporean satellites onboard PSLV workhorse | Watch

<p>After a gap of almost five years, the Indian space agency Indian Space Research Organisation (ISRO) will be performing two rocket launches in the same month.</p>

<p>After launching the third lunar mission Chandrayaan-3 on July 14, the ISRO is geared up for a commercial mission by the PSLV rocket on Sunday (July 30).</p>

<p>The 25-hours 30 minutes countdown for the launch commenced at 5:01 am on Saturday and the vehicle is expected to lift off from the first launchpad of Satish Dhawan Space Centre at 6:31 am on Sunday. The last time that ISRO performed two launches in a month was in November 2018, when ISRO performed launch missions of its LVM3 and PLSV rocket, in quick succession.</p>

<p>The primary passenger of the PSLV C56 rocket will be the 360kg DS-SAR Satellite and it will be placed in a Near-equatorial Orbit (NEO) at 5 degrees inclination and 535 km altitude. The DS-SAR satellite is developed under a partnership between DSTA (representing the Government of Singapore) and ST Engineering.</p>

ISRO's PSLV to launch 7 Singaporean satellites on Sunday, countdown begins

<p><strong>ISRO Aditya L1:</strong>The Indian Space Research Organisation (ISRO) is all set for its first Solar Mission, Aditya L1 which is likely to take off on August 26, 2023. It is the first Indian space mission to study the sun. The sun constantly influences Earth with heat, radiation, and solar wind. The Aditya L1 aims at studying the atmosphere of the Sun as it releases huge amounts of energy into the Solar System. These energies cause several disturbances in the space environment near the Earth.&nbsp;</p>

<p>Aditya L1 spacecraft is planned to be kept in a halo orbit around a point named L1 Lagrange point. The Lagrange point is about 1.5 million km away from Earth in the Earth-Sun system. Keeping the orbit around L1 has the advantage of continuously viewing the sun without any eclipses. The spacecraft contains seven payloads to observe the different layers of the Sun.&nbsp;</p>

<h2><strong>Here’s everything you need to know about Aditya L1</strong></h2>

<h3><strong>Why is the mission named Aditya L1?</strong></h3>

<p>The mission was initially proposed as Aditya 1, a satellite carrying a single payload, and was aimed at observing only the solar corona. It was renamed as Aditya L1 because now it is planned to position at the L1 Lagrange point of the Earth-Sun system and the Aditya L1 satellite carries seven payloads.</p>

<h3><strong>What are the scientific objectives of Aditya L1?</strong></h3>

<p>The Space agency wants to understand Coronal Heating and Solar Wind Acceleration.</p>

<p>The objective is to understand the initiation of Coronal Mass Ejection (CME), flares and near-earth space weather.</p>

<p>ISRO targets to understanding the coupling and dynamics of the solar atmosphere</p>

<p>To know about solar wind distribution and temperature anisotropy.</p>

<h3><strong>What is the uniqueness of the mission?</strong></h3>

<p>The mission is unique in its &nbsp;way as it is the first time spatially resolved solar disk in the near UV band.</p>

<p>The spacecraft has unique CME dynamics close to the solar disk and provides information on the acceleration regime of CME which is not observed continuously.</p>

<p>The Onboard intelligence to detect CMEs and solar flares have unique features to provide optimised observations and data volume.</p>

<p>Spacecraft will use multi-direction observations for directional and energy anisotropy of solar wind.</p>

<h3><strong>What are Lagrange Points?</strong></h3>

<p>Lagrange points are the spots in space where an object tends to stay if put in there. In the Earth-Sun space system, there are 5 Lagrange Points named L1, L2, L3, L4, and L5. L1 lies between the line of Earth and Sun. The distance between L1 and Earth is approximately 1% of Earth-sun distance.&nbsp;</p>

<p>The AdityaL1 mission will subsequently land at the L1 Lagrange Point and it will take around 4 months after the launch for Aditya L1 to reach the desired Lagrange Point.</p>

<h3><strong>Will AdityaL1 do a complete study about the Sun?</strong></h3>

<p>According to ISRO scientists, no space mission can do a complete study because of the limited mass and volume of spacecraft that are sent to Space.&nbsp;</p>

<p>AdityaL1 will examine all the measurements from lagrange point L1 but several phenomena of the sun are multidirectional so it becomes difficult to have a complete study from L1 lagrange point. Therefore, L1 will only examine within its capabilities.&nbsp;</p>

Chandrayaan-3 successfully completes final Earth orbit-raising manoeuvre: ISRO

<p>The Indian space agency ISRO announced the successful completion of engines that would steer the Indian astronaut crew module, during the Gaganyaan human spaceflight missions.</p>

<p>"This test involved five liquid apogee motor (LAM) engines with a thrust of 440N and sixteen reaction control system (RCS) thrusters with a thrust of 100N," the ISRO said.</p>

<p>This test is one in a series of many tests that ISRO intends to conduct under various circumstances, to check the reliability of its service module.</p>

<p>In simple terms, a rocket lifts a spacecraft or crew module to space using the rocket's own propulsive power. Once the crew module is separated from the rocket and ejected into space, it has to rely on its own engines to steer itself, to move into the most precise orbit and even to steer itself back towards earth for re-entering the atmosphere etc. This time, ISRO has tested the systems that would help its crew module perform all of the above and more.</p>

<p>The five LAMs that offer a thrust of 440N each are meant to steer the spacecraft, change its orbit and perform the tasks that require high-thrust. Owing to various factors, spacecrafts are required to fire their on-board engines to makes course corrections, steer clear from space debris and other space objects or satellites etc.</p>

<p>For example, a spacecraft which has to dock with the International Space Station must be able to use its own engines to steer itself towards the space station. However, the LAM are the main engines of the spacecraft and are only placed on one side of the craft.</p>

Chandrayaan-3 update: ISRO successfully performs third orbit-raising manoeuvre

<p>India's tryst&nbsp;with space shot up for the third time on Friday after Chandrayaan-3, the third lunar exploration mission of the world's most populous nation, took off from Sriharikota.</p>

<p>Only three nations have achieved the feat of landing on the Moon's surface so far.</p>

<p>The mission is a follow-up of the Chandrayaan-2 mission, which failed a desired soft landing on the lunar surface nearly four years ago in 2019.</p>

<p>The primary objectives of the Chandrayaan-3 mission are to demonstrate the complete capability of safe landing and exploration on the lunar surface.&nbsp;</p>

<p>Scheduled to reach the Moon's south pole region on August 23, the spacecraft consists of a six-wheeled lander and rover module equipped with payloads to gather valuable data about the Moon's surface.</p>

<h2><strong>How Pragyan rover will leave Indian imprint on&nbsp;moon?</strong></h2>

<p>Beyond its scientific endeavours, the lunar rover, Pragyan, has a symbolic role too.</p>

<p>As it traverses the lunar terrain, the rear wheels of the rover will leave distinct imprints representing the Indian Space Research Organisation and India's national emblem: the Lion Capital of Ashoka at Sarnath.&nbsp;</p>

<p>The ISRO shared a captivating curtain-raiser video on its website, providing a glimpse into the Chandrayaan-3 mission. The video showcases the embossed imprints on the rover.</p>

<p>During the Chandrayaan-2 mission, the ISRO also presented a visual representation of the mission on its YouTube channel. The animated video depicted the lander's arrival on the Moon's surface, followed by the rover commencing its mission after assessing the environment.&nbsp;</p>

Morning brief: India set to launch Chandrayaan-3, PM Modi receives France’s highest civilian award

<p>Few hours are left when billions of dreams will take off from Sriharikota as Chandrayaan-3 will launch into space. Ahead of the historic launch, a special puja (prayer) was performed at a Tamil Nadu temple to seek the blessing of God for a successful mission. &nbsp;</p>

<p>Chandra Preedhi Homam, a two-hours prayer, was performed for the God of Moon at Kailasanathar temple in Thanjavur, Tamil Nadu, ahead of the Chandryaan-3 lift-off at 2:35 pm local time.</p>

<p>The special prayers were performed at the temple in the morning from 8:30- 10:30 am IST, as per our correspondent.&nbsp;</p>

<p>India’s heaviest rocket LVM3 will lift off at 2.35 pm on Friday carrying Chandrayaan-3 spacecraft. The spacecraft in turn holds a lander and a rover. The primary purpose of this mission is to soft-land the Lander on the moon and the rover to do some experiments on the moon soil.</p>

<p>This is the third time special prayers are being arranged for the success of the Indian Space Research Organisation’s (ISRO) moon mission.</p>

<h2><strong>Of faith and science</strong></h2>

<p>A special prayer was also organised for the success of Chandrayaan-1 before the rocket lifted off in 2008, V. Kannan, Retired Manager at the Sri Kailasanathar Temple or Chandranaar Temple told IANS.</p>

<p>Interestingly, prior to the second moon mission, Chandrayaan-2, special prayers were not arranged. The launch originally slated for July 15, 2019, got postponed due to a technical glitch.</p>

<p>According to Kannan, the glitch was thought to be due to the non-offering of prayers to the Moon God. Hence, prior to the Chandrayaan-2 launch on July 22, special prayers, ‘Abhishekam’ and ‘Annadhanam’ were conducted.</p>

<p>The Kailasanathar Temple is a Shiva temple and has the 'Navagrahas'(nine planets) consecrated including the Moon God.</p>

India’s heaviest rocket LVM3 will lift off at 2.35 pm on Friday carrying Chandrayaan-3 spacecraft. The spacecraft in turn holds a lander and a rover. The primary purpose of this mission is to soft-land the Lander on the moon and the rover to do some experiments on the moon soil. This is the third time special prayers are being arranged for the success of the Indian Space Research Organisation’s (ISRO) moon mission. Of faith and science A special prayer was also organised for the success of Chandrayaan-1 before the rocket lifted off in 2008, V. Kannan, Retired Manager at the Sri Kailasanathar Temple or Chandranaar Temple told IANS. Interestingly, prior to the second moon mission, Chandrayaan-2, special prayers were not arranged. The launch originally slated for July 15, 2019, got postponed due to a technical glitch.

‘Chandrayaan-3 scripts new chapter’: PM Modi about successful launch of India’s third lunar mission

<p>The Indian Space Research Organisation (ISRO) successfully launched the Chandrayaan-3 mission from Satish Dhawan Space Centre in Sriharikota at 2:35 pm local time in its second attempt at soft landing on the surface of the moon. The journey to the moon will take around 40 days and the spacecraft is expected to land on the lunar surface by&nbsp;August 23.<br />
<br />
If ISRO can successfully pull off this mission, India will join the exclusive list that has only three countries, the United States, the Soviet Union and China, which were able to make a soft landing on the Moon. In 2013, China emerged as the only country which succeeded in its first attempt with the Chang’e-3 mission.</p>

Chandrayaan-3 is the third instalment of the Chandrayaan series and India's second attempt to achieve a soft landing on the Moon's surface. Only three countries have successfully landed spacecraft on the airless lunar surface. Ahead of the Chandrayaan-3 launch, Indian Space Research Organisation (ISRO) Chairman S Somanath on Monday said that they “will be able to do a soft landing on the Moon” during the mission. In order to achieve this feat, many changes and new additions are made to the third instalment of the Chandrayaan series. It consists of an indigenous Lander module (LM), a Propulsion module (PM), and a rover with the objective of developing and demonstrating new technologies required for interplanetary missions. Also Read | Countdown begins: ISRO to launch Chandrayaan-3 on July 14 | All details here The Lander will have the capability to soft land at a specified lunar site and deploy the rover which will carry out in-situ chemical analysis of the lunar surface during the course of its mobility. The propulsion module will carry the lander from launch vehicle injection to the final lunar 100 km circular polar orbit and separate the two.

Chandrayaan-3: India's third moon mission to launch on July 14. Here's how to watch the historic launch live

<p>India's largest rocket LVM3 stands assembled and ready at the vehicle assembly building in Satish Shawan Space Centre, Sriharikota. ISRO said on Wednesday that the nose cone (payload fairing) of the rocket, which holds the Chandrayaan-3 Lunar spacecraft within, has been fitted atop the launch vehicle. This indicates steady progress towards a launch around July 13&nbsp;or July 14 afternoon, if all goes well. However, ISRO has not yet officially announced a launch date.&nbsp;</p>

<p>On July 7, the 640-ton Launch vehicle is expected to be moved to the Second launch pad at the Indian spaceport. A day or day and a half prior to launch, a countdown timer is started and a crucial phase of multiple health checks on the vehicle and its systems, sub-systems is carried out. It is towards the final stages of the countdown that the earth-storable liquid fuels and the super-cooled cryogenic fuels are filled into the second and third stages of the rocket, respectively.&nbsp;</p>

<p>Dr&nbsp;S Somanath, Chairman, ISRO had earlier told WION that the Chandrayaan-3 lander and rover would retain the names used in Chandrayaan-2. This implies that the Lunar lander will be known as 'Vikram', a tribute to Dr. Vikram A Sarabhai, the brain behind the Indian space programme. The rover will be known as 'Pragyan', a Sanskrit word that means wisdom. We are looking at a Lunar landing around August-end, Dr. Somanath added. The Lunar l sing will have to be conducted at a time when the landing spot is experiencing a Lunar day (roughly spanning 14 earth days). This will help the lander and rover perform experiments within the stipulated mission duration.&nbsp;</p>

<p>India is undertaking its third Lunar mission and second Lunar landing attempt, after the previous mission Chandrayaan-2 could not perform the Lunar soft landing. While barely two kilometres above the Lunar surface, as it was approaching for a vertical landing, ISRO lost contact with the then 'Vikram' Lunar lander. The lander had made a hard landing of the lunar surface, which it did not survive, thus leaving the Lunar landing mission incomplete.</p>

<p>However, the orbiter from Chandrayaan-2 continues to circle the moon and provide science data from its payloads. Therefore, Chandrayaan-3 will not be having an orbiter that is mounted with multiple science payloads. Instead, it will serve as a propulsion module that will help the integrated spacecraft reach Lunar orbit.&nbsp;</p>

<p>While theChandrayaan-3 orbiter weighs lesser than its predecessor, the integrated spacecraft (orbiter, lander, rover) weigh 3.9tons or 3,900kgs, which is approximately 300kgs more than the integrated Chandrayaan-2 spacecraft. However, the payload mass reduced from the orbiter has been added to the Chandrayaan-3 Lunar lander.&nbsp;</p>

<p>The added mass on the Lunar lander comprises more fuel, more ruggedisation, measures for failure tolerance and strengthening of landing legs and increased scientific payloads, larger solar panels for better power generation," Dr S Somanath, Chairman, ISRO told WION. He was responding to WION's question on whether the Chandrayaan-3 spacecraft would weigh lesser than its predecessor (which weighed around 3.6 tonnes or 3,600kgs).&nbsp;</p>

<p>Earlier, Chairman, ISRO had told WION that the launch window for Chandrayaan-3 on board the LVM3 rocket would be between July 12 and July 19. The launch window is the ideal period for a launch mission and any day within that interval would be chosen based on a host of factors. Given that the Indian Lunar spacecraft would require around six weeks to travel from the earth to the moon (a distance of 3,84,000kms), precise calculations are carried out and the launch time is determined down to the minute.</p>

<p>When determining the time of launch, the mission planners consider the weather forecast, a flight path that is free of space debris, the dynamic position of the destination (with respect to earth), the time taken to travel to the destination, the manoeuvres involved, the rocket being used, the purpose of the mission, day or night time at the destination (during the time of landing), the movement and impact of other heavenly bodies etc.&nbsp;</p>

<p>Given that the launch window for Chandryaan-3 is just around a week, ISRO would work towards ensuring that the launch happens in the first few days of the window. It is pertinent to remember that Chandrayaan-2 was originally scheduled for launch on July 15, 2019, but ISRO called off that day's launch, owing to a technical snag that was observed while the rocket's cryogenic fuels were being filled.</p>

<p>ISRO took a week to rectify the issue and finally carried out the launch on July 22 in 2019. Therefore, ISRO's goal would be to launch in the first few days of the window, so that they can have a handful of days at hand, in case of any unexpected technical issues.</p>

<p>Queried about how confident he was about the positive mission outcome of Chandrayaan-3, Dr Somanath had earlier told WION that he is always confident, but space is an unforgiving domain, where only rigorous testing and clear decision-making yield favourable results. Smilingly, making a mention of luck being involved, he said that "even luck comes out of hard work and the perseverance to do the right thing at the right time".</p>

ISRO's LVM3 rocket fully integrated ahead of Chandrayaan-3 launch 

<p>If all goes as per plan, India's heaviest rocket LVM3 (Launch Vehicle Mark 3) will lift off at 14:30hrs (Indian Standard Time) on July 13, from the second launchpad at the Satish Dhawan Space Centre (SDSC) in Sriharikota, carrying India's third Lunar mission- Chandrayaan-3, WION has learnt. ISRO has, however, not confirmed the launch date officially.&nbsp;</p>

<p>At present, the spacecraft has been integrated with the payload adapter, a piece of hardware that connects the spacecraft to the upper stage of the rocket. The 640-tonne LVM3 rocket is in its final stage of integration and the cryogenic upper stage is soon to be stacked atop the vehicle, following which the spacecraft will be mounted, securely nestled in the payload fairing (rocket nose cone). The launch vehicle is expected to be moved from the vehicle assembly building to the second launchpad around July 7.&nbsp;</p>

WION Exclusive: Chandrayaan-3 launch on July 13, lunar landing by August-end

<p>Indicating steady progress towards a mid-July launch, the Indian Space Agency, ISRO shared pictures of its third lunar spacecraft Chandrayaan-3, which has now been mated with the payload adapter. The payload adapter is a piece of hardware that is used to connect the satellite (payload) to the upper stage of a rocket. Once a satellite is mated with the payload dispenser, it is then encapsulated within the payload fairing (nose cone of the rocket) and then stacked onto the launch vehicle.</p>

<p>Dr S Somanath, Chairman, ISRO told WION that the Chandrayaan-3 lander and rover would retain the names used in Chandrayaan-2. This implies that the Lunar lander will be known as 'Vikram', a tribute to Dr Vikram A Sarabhai, the brain behind the Indian space programme. The rover will be known as 'Pragyan', a Sanskrit word that means wisdom. Launched in mid-July, the spacecraft would make a lunar landing towards the end of August, Dr Somanath added.</p>

<p>The lander had made a hard landing on the lunar surface, which it did not survive, thus leaving the lunar landing mission incomplete.

Indicating steady progress towards a mid-July launch, the Indian Space Agency, ISRO shared pictures of its third lunar spacecraft Chandrayaan-3, which has now been mated with the payload adapter.

Indicating steady progress towards a mid-July launch, the Indian Space Agency, ISRO shared pictures of its third lunar spacecraft Chandrayaan-3, which has now been mated with the payload adapter. The payload adapter is a piece of hardware that is used to connect the satellite (payload) to the upper stage of a rocket. Once a satellite is mated with the payload dispenser, it is then encapsulated within the payload fairing (nose cone of the rocket) and then stacked onto the launch vehicle. Dr S Somanath, Chairman, ISRO told WION that the Chandrayaan-3 lander and rover would retain the names used in Chandrayaan-2. This implies that the Lunar lander will be known as 'Vikram', a tribute to Dr Vikram A Sarabhai, the brain behind the Indian space programme. The rover will be known as 'Pragyan', a Sanskrit word that means wisdom. Launched in mid-July, the spacecraft would make a lunar landing towards the end of August, Dr Somanath added.

<p>"NVS series of satellites will sustain and augment the NavIC with enhanced features. This series incorporates L1 band signals additionally to widen the services. For the first time, an indigenous atomic clock will be flown in NVS-01" ISRO said.&nbsp;</p>

<p>Atomic clocks are highly precise timekeeping instruments that are placed within satellites. They offer measurements of time that are precise down to a billionth of a second(nanosecond). Such precision is crucial because they help in offering accurate positioning services. While using satellite-based positioning and navigation services, our position(of the GPS receiver) is determined with respect to its distance from multiple satellites.</p>

<p>When such a calculation happens, the distance value is obtained by multiplying the time(taken for a signal to travel) and the speed of the signal(almost similar to the speed of light). In such cases, (when large values are being multiplied) even a variation of a billionth of a second can lead to an inaccurate distance value(by a few meters or tens of meters). Hence it is necessary to have atomic clocks that can work for several years without even nanosecond-level errors in timekeeping.&nbsp;</p>

<p>Earlier, the NavIC series of satellites were known as IRNSS(Indian Regional Navigation Satellite System). It provides two types of services- Standard Positioning Service (SPS) which is provided to all the users and Restricted Service (RS), which is an encrypted service provided only to the authorised users.</p>

<p>According to ISRO, some of the applications of the IRNSS/NavIC system are Terrestrial, Aerial, and Marine Navigation, Disaster Management, Vehicle tracking, and fleet management, Precise Timing, etc. According to ISRO, NavIC SPS signals are interoperable with other global navigation satellite system (GNSS) signals such as - GPS, Glonass, Galileo, and BeiDou.&nbsp;</p>

<p>ISRO's current series of NavIC satellites were placed in orbit in a phased manner between the years 2013 and 2018 using PSLV rockets. All satellites in the first-generation NavIC series weighed 1,425kg and carried foreign-origin atomic clocks.

<p>The navigation payload of transmits signals for the determination of position, velocity, and time. Rubidium atomic clocks are part of the navigation payload of the satellite.

Reporting the #isro #GSLVF12 🚀🚀🇮🇳🚀🚀lift-off as it happens, from Satish Dhawan #space centre, Sriharikota… 10 mins into flight, so far so good… @isro#india #tech #rocket pic.twitter.com/IcRlSytrgD — Sidharth.M.P (@sdhrthmp) May 29, 2023 × KVS Bhaskar, the Satellite Director for this mission said that this was a satellite launch that everyone in the domain of navigation was looking forward to, as it also operates in L1 band frequency, which is interoperable with International operators (GPS, Glonass, Galileo, and BeiDou) and also contains an indigenously developed atomic clock. NVS-01 is the first in the series of second-generation navigation satellites built by ISRO's UR Rao Satellite Centre in Bengaluru. At present, India uses its Navigation with Indian Constellation(NavIC) series of satellites for civilian and defence navigation, positioning, and timing services in the Indian mainland and even 1500 km beyond India's borders. Watch | Turkey Elections 2023: Erdogan back for another five years × "NVS series of satellites will sustain and augment the NavIC with enhanced features. This series incorporates L1 band signals additionally to widen the services. For the first time, an indigenous atomic clock will be flown in NVS-01" ISRO said. Atomic clocks are highly precise timekeeping instruments that are placed within satellites. They offer measurements of time that are precise down to a billionth of a second(nanosecond). Such precision is crucial because they help in offering accurate positioning services. While using satellite-based positioning and navigation services, our position(of the GPS receiver) is determined with respect to its distance from multiple satellites. When such a calculation happens, the distance value is obtained by multiplying the time(taken for a signal to travel) and the speed of the signal(almost similar to the speed of light). In such cases, (when large values are being multiplied) even a variation of a billionth of a second can lead to an inaccurate distance value(by a few meters or tens of meters). Hence it is necessary to have atomic clocks that can work for several years without even nanosecond-level errors in timekeeping. Earlier, the NavIC series of satellites were known as IRNSS(Indian Regional Navigation Satellite System). It provides two types of services- Standard Positioning Service (SPS) which is provided to all the users and Restricted Service (RS), which is an encrypted service provided only to the authorised users. According to ISRO, some of the applications of the IRNSS/NavIC system are Terrestrial, Aerial, and Marine Navigation, Disaster Management, Vehicle tracking, and fleet management, Precise Timing, etc. According to ISRO, NavIC SPS signals are interoperable with other global navigation satellite system (GNSS) signals such as - GPS, Glonass, Galileo, and BeiDou. ISRO's current series of NavIC satellites were placed in orbit in a phased manner between the years 2013 and 2018 using PSLV rockets. All satellites in the first-generation NavIC series weighed 1,425kg and carried foreign-origin atomic clocks. All IRNSS/NavIC series satellites carried two types of payloads – navigation payload and ranging payload. The navigation payload of transmits signals for the determination of position, velocity, and time. Rubidium atomic clocks are part of the navigation payload of the satellite. The ranging payload of these satellites consists of a C-band transponder which facilitates accurate determination of the range of the satellite. Speaking to reporters prior to the launch day, Chairman ISRO, Dr.S. Somanath said that only four of the existing fleet of seven NavIC satellites were operational now. Instead of replacing the three defunct satellites of the old generation, ISRO is launching a fleet of five next-gen NavIC satellites, of which NVS-01 would be the first, he added. The rationale behind launching a new fleet of five satellites is the fact that the existing constellation would be defunct in a few years(owing to the completion of mission life). Hence, it would not be prudent to replace the old fleet. It is expected that two next-gen NavIC satellites will be launched every year.

Confident that GSLV will launch NASA-ISRO satellite NISAR next year: ISRO on GSLV-F12 success

<p>The countdown for ISRO's (Indian Space reserach Organisation) GSLV F12/NVS-01 launch mission commenced at 7:12 am Sunday, ahead of the lift-off that is scheduled for 10:42 am Monday, WION has learnt. The countdown is the final phase prior to launch where the launch vehicle's liquid and cryogenic fuels are filled and the final health checks of crucial systems are carried out.</p>

<p>The GSLV rocket that stands tall at the second launchpad at the Satish Dhawan Space Centre, Sriharikota, is meant to place a 2,332 kg navigation satellite NVS-01 into a Geosynchronous Transfer Orbit (GTO). The GTO is a temporary parking orbit, into which the satellite will be hurled by the rocket. There on, the satellite will independently use its onboard propulsion systems to perform orbit-raising maneuvres and reach its intended orbit.&nbsp;</p>

<p>This will be the Indian space agency ISRO's fourth launch mission of the calendar year 2023. Thus far in 2023, ISRO has launched its smallest rocket SSLV, the most-flown workhorse rocket PSLV and the heaviest rocket LVM3. Monday's launch will add the GSLV to the list — marking the launch of all four operational vehicles of ISRO in a short span of four months.&nbsp;</p>

What does India look like from space? ISRO's new satellite images have the answer

<p>The Indian Space Research Organisation (ISRO), early Sunday (March 26) launched its largest and heaviest Launch Vehicle Mark-3 (LVM3) rocket from the second launchpad of the Satish Dhawan Space Centre, Sriharikota. It also marked the Indian space agency’s sixth consecutive successful flight of LVM3-M3.&nbsp;</p>

<p>The rocket placed 36 satellites belonging to the OneWeb Group Company in their intended 450 km circular orbit with an inclination of 87.4 degrees, said ISRO, in a statement. The LVM3 was carrying a total payload of 5,805 kg to Low Earth Orbit (LEO) and was launched at 09:00:20 hours (local time).&nbsp;</p>

ISRO's largest rocket LVM3 lifts off successfully on 2nd commercial mission

<p>Announcing the successful launch of India's heaviest rocket LVM3 in its second commercial mission, the Indian Space Research Organisation (ISRO) said that all 36 satellites belonging to OneWeb were injected into the intended orbit.</p>

<p>In his post-launch address, ISRO Chairman Dr S Somanath said that ISRO is gearing up for impending launches of its PSLV, GSLV Mk2 and LVM3 rockets in the coming months.</p>

<p>Acknowledging that the LVM3 vehicle did extremely well in its 9 am launch mission on Sunday, Somanath said that the satellites were placed in orbit with minimal disturbance.</p>

<p>As per the plan, the rocket deployed 16 satellites in orbit initially and 20 satellites were deployed thereafter. ISRO initially confirmed the successful placement of 16 satellites in orbit and said that they would update regarding the deployment of the 20 remaining satellites when they receive tracking information about the same.</p>

<p>When satellites are deployed in space, often they are not immediately visible to ground-based tracking stations or even ship-borne tracking stations. It takes some time before satellites make the orbit and are visible in the range of the tracking stations.</p>

<p>D Radhakrishnan, Chairman of NSIL, the commercial arm of ISRO, said that this was an extremely momentous day. Just as was done in the October 2022 launch, the 'C25' cryogenic stage was used to perform a series of complex manoeuvres to inject the OneWeb satellites in nine batches of four each. He also reassured the customer OneWeb that ISRO-NSIL would be happy to provide more launch solutions as required.</p>

<p>S Mohana Kumar, the Mission Director of the LVM3-M3 mission said that the LVM3 rocket had shown its might and ruggedness in carrying heavy payloads to the required orbit. He also acknowledged team ISRO for having completed the launch campaign (the entire process of integrating, stacking, assembling and launching the rocket) of India's largest rocket in a record time of 72 days.</p>

<p>"We have done the rocket assembly in the 2nd vehicle assembly building and the entire vehicle integration was carried out under a single roof,” he said. He also thanked ISRO's numerous industry partners for supplying thousands of components and hardware to execute the launch successfully.</p>

<p>Referring to the steady and swift progress towards India's high-profile 'Gaganyaan' astronaut mission, chairman Somanath said that the first stage 'S200' twin boosters used on the LVM3-M3 mission was designed with higher margins and features geared towards Gaganyaan, he stated that progress towards Gaganyaan is happening incrementally.</p>

<p>As part of Gaganyaan, the Indian space agency is human-rating the LVM3 rocket (modifying it to be suitable, safe and reliable for ferrying humans to space).

Largest rocket LVM3 places 36 satellites in orbit, augments confidence for Gaganyaan: ISRO chairman

<p>India's largest rocket LVM3 is at the second launch pad of the Satish Dhawan Space Centre in Sriharikota, getting ready for the lift-off at 9 am on&nbsp;Sunday, March 26. The launch will mark the sixth flight of the LVM3 rocket. However, there's one thing that makes this LVM3 M3 vehicle different from all the LVM3 rockets that flew before it — this rocket has a changed colour scheme at the cryogenic stage, the upper central portion of the rocket (that towers above the two boosters on the side). Instead of the standard grey/black, this time around the C25 cryogenic stage sports white.</p>

<p>To understand the reason and the science behind the colour change, WION spoke to Dr S. Unnikrishnan Nair, Director, Vikram Sarabhai Space Centre (VSCC), ISRO. Dr Nair heads VSSC, which is ISRO's lead facility for developing its operational rockets and future space transportation systems.<br />
<br />
A rocket specialist with significant contributions towards launch vehicles and manned vehicle systems, Dr Nair explained that the reason&nbsp;behind the colour change takes into account environmental-friendly manufacturing processes, better insulation properties and the use of lightweight materials.</p>

<p>The C25 stage is a cryogenic stage, which comprises a cryogenic engine and fuel tanks that hold tons of frozen fuel — liquid oxygen and liquid hydrogen, along with its related systems. Engineering a cryogenic stage has unique design challenges, as liquid Hydrogen is stored at -253 degree&nbsp;centigrade and liquid Oxygen at -195 degree centigrade. To store these cryogenic fluids and maintain them at supercooled temperatures, special multi-layer insulation is provided for the fuel tanks and other structures.</p>

<p>For the first five launches of the LVM3 rocket, ISRO had been using a grey/black insulation material for the C25 stage and now that material has been replaced with a white coloured one.</p>

<p>"The earlier insulation material was based on Hydrochlorofluorocarbon (HCFC) and owing to environmental concerns, we have switched to greener alternatives based on chemicals such as Hydrofluoro-Olefine," said Nair.</p>

<a class="close-mark close-div" href="#" id="jqclosemark">×</a></div>

<p>HCFCs are globally regarded as unsafe as they contain chlorine and have the potential to deplete the ozone layer. Owing to this, there are certain manufacturing caps on this material and ISRO is avoiding its use.</p>

<p>Regarding the grey/black colour being replaced with white, he added that the earlier anti-static coating (meant to prevent a build-up of static electricity) has been replaced with a white one. He reasoned that this was owing to solar absorptivity, as dark colours like black attract a lot of heat and affect the temperature of the cryogenic fuels.</p>

<p>Simply put, the use of white is similar to how cricketers wear all-whites for test matches when they have to play all day. White is meant to reflect the sun's heat away, particularly when the fully-built rocket stands exposed to the sun for several days at the launchpad.</p>

<p>Nair also explained that it is not easy to add an extra coat of paint or extra layer of material to a rocket's upper body, as every kilogramme of weight comes at a premium.</p>

<p>Every added component or layer of coating/paint adds to the rocket's weight and affects the vehicle's payload-carrying capacity. So, we have to keep in mind the science, the utility and also the environmental aspects. Hence, it takes time to develop new materials that are lightweight, suited for the purpose and at the same time cost-effective and environment-friendly.</p>

Regarding the grey/black colour being replaced with white, he added that the earlier anti-static coating (meant to prevent a build-up of static electricity) has been replaced with a white one. He reasoned that this was owing to solar absorptivity, as dark colours like black attract a lot of heat and affect the temperature of the cryogenic fuels. Simply put, the use of white is similar to how cricketers wear all-whites for test matches when they have to play all day. White is meant to reflect the sun's heat away, particularly when the fully-built rocket stands exposed to the sun for several days at the launchpad. ALSO READ | BrahMos in talks to sell missile to nations in South East Asia, Middle East: CEO Atul Rane Nair also explained that it is not easy to add an extra coat of paint or extra layer of material to a rocket's upper body, as every kilogramme of weight comes at a premium. Every added component or layer of coating/paint adds to the rocket's weight and affects the vehicle's payload-carrying capacity. So, we have to keep in mind the science, the utility and also the environmental aspects. Hence, it takes time to develop new materials that are lightweight, suited for the purpose and at the same time cost-effective and environment-friendly. WATCH WION LIVE HERE:

ISRO's C25 cryogenic stage now sports white, ditches black; What's the science behind it?

<p>The Indian space agency has announced that its largest rocket LVM3 will be launched at 9am on March 26 from the second launchpad at the Satish Dhawan Space Centre in Sriharikota. This will be the rocket's sixth mission overall and its second commercial mission. Notably, this is also the shortest duration in which ISRO is carrying out two missions of the LVM3 rocket - on October 23rd, 2022 and March 26, 2022. Such quick execution is being carried out in order to meet the timelines of the customer whose satellites are being launched.&nbsp;</p>

<p>Tweeting the launch time and date, ISRO also shared pictures of the LVM3 being rolled out from the Vehicle Assembly Building to the second launchpad and those of the vehicle standing at the launchpad. OneWeb has been utilising the launch services of SpaceX, Arianespace and ISRO to place all its 1st generation constellation satellites in orbit OneWeb satellites have flown 17 times to date, and ISRO will be carrying the 18th set.&nbsp;</p>

<p>"We are one launch away from achieving global coverage. This last launch with ISRO/NSIL will mark over 600 satellites in space, which is the number needed to go commercially live" a OneWeb spokesperson told WION. The firm's services are already live for customers 24x7 in 50 degrees north latitude- Alaska, Canada, Greenland, UK and Northern Europe. By the end of this year, we plan to initiate services across the Globe, it was added.&nbsp;</p>

<p>This is a dedicated commercial mission being carried out through ISRO's commercial arm NSIL (NewSpace India Limited). The rocket will carry 36 OneWeb Gen-1 satellites with a total mass of 5,805 kg, into a 450 km circular Low Earth Orbit with an inclination of 87.4°. &nbsp;OneWeb is a UK-based firm backed by India's Bharti Group. OneWeb aims to offer high-speed, low-latency internet connectivity from space via its constellation of satellites in Low Earth Orbit.&nbsp;</p>

<p>LVM3 is a three-stage vehicle with two S200 solid motors as the first stage, L110 twin liquid engines as the second stage and a final C25 cryogenic upper stage. This 43.5 m tall vehicle has a lift-off mass of 643 tonnes. ISRO said that the vehicle's cryogenic stage is uniquely designed to orient and re-orient in orthogonal direction to meet the customer requirements of injecting satellites precisely and with a gap to avoid a collision. Ejecting 36 satellites is a complex manoeuvre that ISRO carried out during the earlier OneWeb launch in October 2022 as well.&nbsp;</p>

<p>OneWeb had signed a pact with NSIL and ISRO for placing a total of 72 satellites in orbit(in batches of 36). This deal has raked in more than Rs.1000cr revenue for the Indian Government-run space agency. It also provides an opportunity for ISRO to demonstrate the capability and reliability of their largest rocket for offering commercial launch services. Until October 2022, ISRO's LVM3 or GSLV Mk3 rocket was being used only for fulfilling India's national missions such as Chandrayaan-2 and launching heavy satellites. Notably, the LVM3 has performed successful launches in all its missions to date. The March 26th launch of LVM3 will be the rocket's sixth mission.&nbsp;</p>

<p>"Subject to all Regulatory approvals being in place, we are confident of the commencement of our services later this year for India and have announced distribution agreements with Hughes to provide services" the OneWeb spokesperson told WION, when queried about service would be rolled out in India.&nbsp;</p>
