The total solar eclipse was not visible in India but the Aditya-L1 spacecraft has a device known as Visible Emission Line Coronagraph (VELC), which is capable of artificially blocking the light of the Photosphere and studying the light from the Corona. This is the same as the view during a Solar eclipse. Watch in for more details!

How does Aditya-L1 spacecraft create an artificial solar eclipse?

People in the US, Canada, and Mexico are waiting to witness the total solar eclipse on April 8. Though India's first space-based solar observatory, Aditya L1, is continuously studying the Sun. It won't be able to observe total solar eclipse.

Aditya-L1: India’s first solar mission successfully enters final orbit for uninterrupted sun observation

India's Maiden Sun studying mission Aditya-L1 has completed one month of its four month voyage to in Space. The craft has traveled nearly a million kilometres away from the Earth.

India: Aditya L1, ISRO’s mission to study Sun, to be placed in final orbit

<p>India’s maiden&nbsp;solar mission Aditya L1&nbsp;will reach its destination, the Lagrangian point (L1) which is located 1.5 million km from Earth, on January 6, Indian Space Research Organisation (ISRO) chairman S Somanath said on Friday (Dec 22).</p>

<p>The mission, the first Indian space-based observatory to study the Sun from a halo orbit L1, was launched by ISRO on September 2 from the Satish Dhawan Space Centre (SDSC) at Sriharikota. “Aditya L1 will enter the L1 point on January 6. That is what is expected. Exact time will be announced at appropriate time,” Somanath told mediapersons on the sidelines of the Bharatiya Vigyan Sammelan organised by Vijnana Bharati, an NGO working to popularise science.</p>

<p>“When it reaches the L1 point, we have to fire the engine once again so that it does not go further. It will go to that point, and once it reaches that point, it will rotate around it and will be trapped at L1,” he said. Once Aditya L1 reaches its destination, it will help measure various events happening on the Sun for the next five years. “Once it is successfully placed on L1 point, it will be there for the next five years, gathering all the data which are very important not for India alone but for the entire world.</p>

<p>The data will be very useful to understand the dynamics of the Sun and how it affects our life,” the ISRO chief said. How India is going to become a technologically powerful country is very important, he said while addressing the gathering. ISRO has made a plan to build an Indian space station, called ‘Bharatiya space station’ during the ‘Amrit Kaal’ as per Prime Minister Narendra Modi’s instructions, Somanath said.</p>

<p>“In the space sector we are seeing an emergence of new actors. We are going to support, encourage and build the economy around the new generation,” he said, adding that India cannot become a leader in everything and that it should focus on those sectors where it can.</p>

Aditya L1 mission will reach destination on Jan 6: ISRO chief

<p>Aditya-L1, India's first mission to study the Sun will reach its destination, the Lagrange Point 1 (L1) in the first week of January 2024, said Jitendra Singh, India's Minister of State (Science and Technology). The Aditya-L1 mission was launched by the Indian Space Research Organisation (ISRO) in February this year.</p>

<p>Aditya-L1 mission reached a major milestone recently as it captured the first complete images of the Sun. The images were taken with the help of the Solar Ultraviolet Imaging Telescope (SUIT) instrument onboard Aditya-L1. SUIT has various filters which it uses to capture the Sun's photosphere and chromosphere in a specific wavelength range.</p>

<p>ISRO says that the observations made during the ADITYA-L1 mission will help scientists examine and gain a better understanding of the magnetised solar atmosphere. This will in turn yield important insights which will also make us better understand the impact of solar radiation on climate here on Earth.</p>

India's 'Aditya-L1' to reach Lagrange Point 1 in January first week: Minister

<p>While speeding on an expressway in the cruise control mode, once in a while the driver has to intervene and steer the vehicle on its intended lane. Likewise, when travelling at a speed that measures several thousand kilometres per hour, it is necessary to gently steer a spacecraft to ensure it remains on the ideal path to its destination. The Indian space agency ISRO has just completed one such steering manoeuvre with its Aditya-L1 sun-study craft that is cruising towards its destination in interplanetary space.&nbsp;</p>

India's Maiden Sun study Mission Aditya-L1 has completed one month of its 4 month Voyage in Space. The craft has travelled nearly for million kilometers away from the Earth. However, at its destination, there's some kind of traffic. In the next report, we will tell you more about how this traffic will be managed in space.

One month since launch, Aditya-L1 covers 920,000 km

<p>Before heading on out a long drive, don't we assess the traffic situation and look at the possible bottlenecks on an app? Likewise, space agencies constantly monitor what is known as 'Space Situational Awareness' (SSA). Simply put, SSA is like the traffic data for a particular region in space - it mentions the number of spacecraft or crewed crafts operating in orbit and also helps predict the risk of them coming within the vicinity of each other and even colliding.</p>

<p>Based on such data and resultant calculations, each space agency draws its own conclusion and decides to manoeuvre its spacecraft and prevent danger, while also sharing information with the other concerned parties (nations or private firms) who operate spacecraft in the region.&nbsp;</p>

<p>Launched into Earth's orbit on Sep 2, India's Aditya-L1 craft had been circling the Earth and gradually pushing itself further away from Earth&nbsp;for a little more than two weeks. On Sep 18, the craft slingshot itself totally out of Earth's orbit and commenced a journey that would take it to its destination- the Earth-Sun Lagrangian Point 1, which is 1.5 million kilometres away from Earth.&nbsp;</p>

<p>L1 is a significant vantage point because it is situated between the Sun and Earth, making it an ideal location for spacecraft, as this spot allows continuous observation of the Sun. From the L1 point, spacecraft can continuously communicate with the ground stations on Earth and have an unobstructed view of celestial bodies. These orbits are well-suited for scientific missions like Aditya which will act like a solar observatory around L1.&nbsp;</p>

<p>In the past, various missions have stayed put at the Sun-Earth L1 point, including the International Sun-Earth Explorer (ISEE-3), the Genesis mission, ESA's LISA Pathfinder, China's Chang'e 5 lunar orbiter, and NASA's Gravity Recovery and Interior Recovery (GRAIL) mission. These missions have contributed to mankind's understanding of space and the ability to monitor space weather events.</p>

<p>At present, four operational spacecraft are stationed at the Sun-Earth L1 point. They provide vital early warnings on adverse space weather events that help protect orbiting space assets and ground-based infrastructure. The four crafts are- NASA WIND(to observe the unperturbed solar wind before reaching the magnetosphere of Earth), NASA-ESA SOHO(Solar and Heliospheric Observatory- to study the sun and Heliosphere) NASA ACE(Advanced Composition Explorer - observe particles of the solar wind, and of galactic origins) and NASA DSCOVER (Deep Space Climate Observatory to Monitor space weather and climate, deep space Earth observation).&nbsp;</p>

<p>While there are only four crafts that are far apart circling the L1 point, and India's Aditya expected to join them as the fifth in January 2024, it is still necessary to assess the traffic and possible collision risk. "Despite the extremely sparse population in L1 point and the vast separation between them, close approach assessment for an operational spacecraft at Lagrange Point Orbit (LPO) is desirable because of the large positional uncertainty and sensitivity to other perturbative forces," ISRO said.&nbsp;</p>

<p>Generally, to determine the orbit of crafts circling Lagrangian Point 1, tracking data collected over a few days is required. The accuracy of the orbit so calculated might not be very accurate. Therefore, ISRO said that they plan to carry out such analysis periodically to ensure safety and avoid any possibility of close approaches with other neighbouring spacecraft, with the support from NASA-JPL.&nbsp;</p>

<p>It is common for space agencies to predict the path and orbit of their satellites. In case a close approach or risk of collision with another nation's satellite is predicted, then both involved parties take a decision to manoeuvre one or both of their crafts. For example, India's Chandrayaan 2 orbiter which circles the moon, had to avoid collision with foreign satellites on many instances, over the last four years.&nbsp;</p>

ISRO to work with NASA and manage traffic around Aditya-L1's destination 

<p>After 17 days of circling Earth, India's solar observatory Aditya-L1 craft has been slingshot on a long journey towards its destination, 1.5 million kilometres away from Earth. In the wee hours of Tuesday (Indian Standard Time), ISRO issued commands to fire the on-board engines of the Aditya-L1 craft, thereby granting it adequate departure energy to travel on the trajectory that will take it to the Sun-Earth Lagrangian Point 1.</p>

<p>This point is at 1 percentage distance of the 150 million kilometre Earth-Sun distance.&nbsp;</p>

<p>"The spacecraft is now on a trajectory that will take it to the Sun-Earth L1 point. It will be injected into an orbit around L1 through a maneuver after about 110 days," ISRO said.&nbsp;</p>

<p>Notably, Aditya-L1 is the fifth&nbsp;consecutive Indian spacecraft to be slingshot from Earth's orbit towards its destination in interplanetary space or towards a celestial body.</p>

<p>As Indian rockets do not possess adequate lifting power to directly offer adequate departure velocity to spacecraft and hurl them to faraway destinations, India uses what is commonly known as the 'slingshot technique'.</p>

<p>This method has been deployed successfully in missions such as&nbsp;Chandrayaan-1 (2008), Mangalyaan (2013), Chandrayaan-2 (2019), Chandrayaan-3 (2023) and Aditya-L1.&nbsp;</p>

<p>Aditya-L1 and other spacecraft listed above were placed in an elliptical orbit around the Earth. Typically, satellites that are meant to remain in orbit around the Earth are placed in a circular orbit. So, at all times the craft is equidistant from earth.&nbsp;</p>

India's Aditya L1 mission to study Sun strikes major landmark with collection of scientific data

India's ambitious Sun Mission has achieved yet another milestone. The Aditya-L1 spacecraft has successfully completed its fourth Earthbound orbit raising manoeuvre. ISRO took to the social media platform X to confirm the success of the manoeuvre.

Aditya L-1: India's sun mission completes fourth manoeuvre orbit

<p>Aditya L1, India’s maiden space-based mission to study the Sun, successfully completed its fourth Earth-bound manoeuvre in the early hours of Friday (September 15), said the Indian Space Research Organisation (ISRO). The manoeuvre was said to be a crucial step as the Indian space agency seeks&nbsp;to place the spacecraft in a halo orbit around the Lagrange Point 1 (L1) of the Sun-Earth system.</p>

<h2><strong>Aditya-L1 completes&nbsp;fourth Earth-bound manoeuvre</strong></h2>

<p>“The fourth Earth-bound maneuvre (EBN#4) is performed successfully,” said ISRO, in a post on X, formerly Twitter. It added, “ISRO’s ground stations at Mauritius, Bengaluru, SDSC-SHAR and Port Blair tracked the satellite during this operation, while a transportable terminal currently stationed in the Fiji islands for Aditya-L1 &nbsp;will support post-burn operations.”</p>

<p>After the latest manoeuvre, the new orbit attained is 256 km x 121973 km, according to the Indian space agency. “The next maneuvre Trans-Lagragean Point 1 Insertion (TL1I) – a send-off from the Earth – is scheduled for September 19, 2023, around 02:00 Hrs. IST,” said ISRO.&nbsp;<br />

<h2><strong>About Aditya-L1 mission</strong></h2>

<p>India’s maiden sun mission was launched on September 2&nbsp;from the Second Launch Pad of the Satish Dhawan Space Centre (SDSC) in Sriharikota. The spacecraft has undergone three Earth-bound manoeuvres, with the first, second and third taking place on September 3, 5 and 10 respectively.&nbsp;</p>

<p>The manoeuvres are being performed during the spacecraft’s 16-day journey around the Earth where the spacecraft will gain the necessary velocity for its further journey to L1. The L1 point was discovered by mathematician Joseph Louis Lagrange.&nbsp;</p>

<p>It is considered to be the most significant of the Lagrangian points for observation of the Sun.</p>

<p>Aditya-L1 is equipped with seven scientific payloads developed indigenously by the ISRO and various national research laboratories, including the Indian Institute of Astrophysics (IIA) and the Inter-University Centre for Astronomy and Astrophysics (IUCAA), in the Indian cities of Bengaluru and Pune, respectively.</p>

<p>These payloads are designed to study the photosphere, chromosphere, and the outermost layers of the Sun, known as the corona, using electromagnetic, particle, and magnetic field detectors.</p>

<p>Positioned at the advantageous L1 point, four of these payloads will directly observe the Sun, while the remaining three will conduct in-situ studies of particles and fields at Lagrange point L1.&nbsp;</p>

<p>Notably, the launch of Aditya-L1 came barely 10 days after ISRO successfully soft-landed the Chandrayaan-3 craft near the lunar south pole, thereby making India the first nation to do so.</p>

Aditya L1, India’s maiden space-based mission to study the Sun, successfully completed its fourth Earth-bound manoeuvre in the early hours of Friday (September 15), said the Indian Space Research Organisation (ISRO).

Aditya L1, India’s maiden space-based mission to study the Sun, successfully completed its fourth Earth-bound manoeuvre in the early hours of Friday (September 15), said the Indian Space Research Organisation (ISRO). The manoeuvre was said to be a crucial step as the Indian space agency seeks to place the spacecraft in a halo orbit around the Lagrange Point 1 (L1) of the Sun-Earth system. Aditya-L1 completes fourth Earth-bound manoeuvre “The fourth Earth-bound maneuvre (EBN#4) is performed successfully,” said ISRO, in a post on X, formerly Twitter. It added, “ISRO’s ground stations at Mauritius, Bengaluru, SDSC-SHAR and Port Blair tracked the satellite during this operation, while a transportable terminal currently stationed in the Fiji islands for Aditya-L1 will support post-burn operations.” After the latest manoeuvre, the new orbit attained is 256 km x 121973 km, according to the Indian space agency. “The next maneuvre Trans-Lagragean Point 1 Insertion (TL1I) – a send-off from the Earth – is scheduled for September 19, 2023, around 02:00 Hrs. IST,” said ISRO. Aditya-L1 Mission: The fourth Earth-bound maneuvre (EBN#4) is performed successfully.

The L1 point was discovered by mathematician Joseph Louis Lagrange. It is considered to be the most significant of the Lagrangian points for observation of the Sun. Aditya-L1 is equipped with seven scientific payloads developed indigenously by the ISRO and various national research laboratories, including the Indian Institute of Astrophysics (IIA) and the Inter-University Centre for Astronomy and Astrophysics (IUCAA), in the Indian cities of Bengaluru and Pune, respectively. These payloads are designed to study the photosphere, chromosphere, and the outermost layers of the Sun, known as the corona, using electromagnetic, particle, and magnetic field detectors.

India’s Aditya-L1 mission successfully undergoes fourth Earth-bound manoeuvre, says ISRO

<p>Indian Space Research Organisation (ISRO) is gearing up to carry out the&nbsp;fourth Earth-bound manoeuvre in its Aditya-L1 mission. The manoeuvre will take place at 2 am IST on September 15 (2330 GMT on September 14). It is a crucial step as the Indian space agency is seeking to place the spacecraft in halo orbit around the Lagrange Point 1 (L1) of the Sun-Earth system.</p>

<p>The scheduled manoeuvre is part of a series of orbit-raising manoeuvres which will prepare the spacecraft for its journey further to the L1 point.</p>

<p>India's first space-based solar observatory was launched on September 2. Since then, three Earth-bound manoeuvres have been successfully carried out. The most recent took place on September 10. At the end of the third manoeuvre, the Aditya L1 spacecraft attained an orbit of 296 km x 71676 km, as per data released by ISRO.</p>

<p>The fourth manoeuvre will further raise the spacecraft's orbit.</p>

<p>The L1 point was discovered by mathematician Joseph Louis Lagrange. It is considered to be the most significant of the Lagrangian points for observation of the Sun. A spacecraft that's placed in a halo orbit around the L1 point would be in a position to observe the Sun continuously without any eclipses or occultation. This will help to observe solar activities in real-time.</p>

<p>Aditya-L1 is carrying seven payloads. These are designed for various layers of the Sun. Out of seven, four will directly view the Sun. The other three payloads will perform in-situ studies of particles and fields at the L1 point.</p>

<p>The instruments on Aditya-L1 are expected to provide important information about coronal mass ejection, coronal heating, pre-flare and flare activities among other solar phenomena of importance.</p>

<p>India is fresh off the success of the Chandrayaan-3 mission. With a successful landing near the Moon's south pole, India has become the first country to land a spacecraft in this region. The rover and the lander are currently in sleep mode with chances of waking up again on Sep 22.</p>

India's Aditya L1 mission to study Sun completes second Earth-bound manoeuvre

After the success of Chandrayaan-3 the entire world is tuned into what India is doing in the space sector. India wakes up to another big update this time on its maiden solar mission. The Indian space agency ISRO has successfully completed the second Earthbound manoeuvre of the Aditya-L1 spacecraft.

Aditya-L1 mission: India's maiden solar mission crosses another milestone

The ambitious first mission to study the Sun has been launched by the Indian Space Research Organization. The Aditya L1 mission was due to launch on Saturday from Sriharikota's Satish Dhawan Space Center and travel for four months to Lagrange Point 1.

Aditya-L1: After lunar landing, India eyes for the sun

<p>India's Aditya-L1 craft, the country's maiden mission to study the Sun has performed its maiden Orbit Raising Manoeuvre (fired its on-board engines to kick itself further away from earth). The craft was placed in an elliptical (egg-shaped) orbit around the earth by a PSLV-XL rocket&nbsp;around 1 PM, Indian Standard Time on September 2nd.</p>

<p>Meanwhile, the Indian moon probe Chandrayaan-3 is being 'put to sleep' near the Lunar South Pole, as the Lunar night (fortnight-long on earth) fast approaches.&nbsp;</p>

<p>"Aditya-L1 Mission: The satellite is healthy and operating nominally. The first Earth-bound maneuvre (EBN#1) is performed successfully from ISTRAC, Bengaluru. The new orbit attained is 245km x 22459 km. The next maneuvre (EBN#2) is scheduled for&nbsp;September 5, 2023, around 03:00&nbsp;Hrs. IST" ISRO said on X, formerly known as Twitter on September 3rd.</p>

<p>"Chandrayaan-3 Mission: The Rover completed its assignments. It is now safely parked and set into Sleep mode. APXS and LIBS payloads are turned off. Data from these payloads is transmitted to the Earth via the Lander. Currently, the battery is fully charged. The solar panel is oriented to receive the light at the next sunrise expected&nbsp;on September 22, 2023. The receiver is kept on. Hoping for a successful awakening for another set of assignments! Else, it will forever stay there as India's lunar ambassador," ISRO posted on X on September 2nd.</p>

<p>While Aditya-L1 is a mission to study the sun, it would be travelling only 1 per cent&nbsp;of the Earth-Sun distance, unlike NASA's Parker Solar Probe&nbsp;that has flown a few million miles in the vicinity of the Sun.</p>

<p>The Earth-Sun distance is approximately 150 million kilometres.</p>

<p>The launch of Aditya-L1 comes barely 10 days after India soft-landed its Chandrayaan-3 craft (comprising a lander and rover) on the moon.&nbsp;</p>

<p>"Studies related to the Sun can be carried out from ground-based observatories, but they are limited by the day-night cycle. So, an agency would require multiple stations across the earth to study the sun continuously, but each of these observatories would offer their own data&nbsp;(based on the unique characteristics of the equipment). Also, the earth's atmosphere and dust particles scatter the radiation coming in from the sun and affect the quality of the data" Prof Ramesh from the Indian Institute of Astrophysics told WION.&nbsp;</p>

<p>Chandrayaan-3 soft-landed near the Lunar South Pole on August 23rd.&nbsp;</p>

<p>Over the last 11 days, the Chandrayaan-3 lander and rover have been performing in-situ experiments with their respective payloads and sharing the data.</p>

<p>However, the end of the Lunar day time is closing in fast on the Vikram Lander and Pragyan Rover. As the duo are solar-powered, they would not be able to function during the fortnight-long Lunar night.&nbsp;</p>

<p>"The Chandrayaan-3 Lander and Rover are functional and our payload teams are doing all th work... The Rover has traversed a distance of 100meters from the lander..." Dr.S.Somanath, Chairman, ISRO, said following the successful launch of the Aditya-L1 solar observatory satellite.&nbsp;</p>

<p>On average, the temperature during the Lunar day could be around 120degrees Centigrade(For earthlings - that's much more than the boiling point of water or more than twice the hottest recorded temperatures on earth), whereas the Lunar nights could get as cold as -130degrees Centigrade (that's almost twice the coldest temperature recorded on the Earth).</p>

Aditya L1 launch live streaming: Here's how to watch ISRO's first solar mission launch on TV & online

Aditya L1 shall be the first space-based Indian mission to study the Sun. The spacecraft shall be placed in a halo orbit around the Lagrange point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the Earth. A satellite placed in the halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultation/eclipses. This will provide a greater advantage of observing solar activities and their effect on space weather in real-time.

Aditya L1: First Indian space mission to study sun

<p>The Indian Space Research Organisation (ISRO), which on Saturday (September 2) marked another milestone with the launch of its solar mission, Aditya -L1, also gave us an important update about its moon mission Chandrayaan-3 and said that the Pragyan rover has successfully traversed 100 metres on the lunar surface.&nbsp;</p>

<h2><strong>Chandrayaan-3 mission update</strong></h2>

<p>Both Vikram Lander and Pragyan Rover are arguably the two most important components of the country’s lunar mission.&nbsp;In a recent update, ISRO said the latter which is crawling on its six independently movable wheels on the lunar surface has moved 100 metres away from the former.&nbsp;</p>

<p>The Indian Space agency after announcing the successful launch of Aditya L-1, on X (formerly known as Twitter) said, “Meanwhile, over the Moon, Pragyan Rover has traversed over 100 meters and continuing.”&nbsp;</p>

<p>They also posed an image of the path taken by the Pragyan rover and showed the total traverse distance as 101.4 metres.&nbsp;<br />

“The good news is that the rover has moved almost 100 metres from the lander and we are going to start the process of making both of them sleep in the coming one or two days because they have to withstand the night,” said the ISRO chief.&nbsp;</p>

<p>This comes as temperatures during the lunar night are expected to plummet below -200 degrees Celsius, said Dr&nbsp;Somanath, on Saturday.&nbsp;</p>

<p>In an update later that evening, ISRO took to X and wrote, "The Rover completed its assignments".&nbsp;</p>

<p>It added, "It is now safely parked and set into Sleep mode. APXS (Alpha Particle X-ray Spectrometer) and LIBS (Laser Induced Breakdown Spectroscope) payloads are turned off," referring to the rover's instruments for deriving the elemental composition in the vicinity of the landing site.</p>

<p>The Indian space agency also said that it is hoping for a "successful awakening" for further assignment or else "it will forever stay there as India's lunar ambassador."</p>

The Indian Space Research Organisation (ISRO), which on Saturday (September 2) marked another milestone with the launch of its solar mission, Aditya -L1, also gave us an important update about its moon mission Chandrayaan-3 and said that the Pragyan rover has successfully traversed 100 metres on the lunar surface.

The Indian Space Research Organisation (ISRO), which on Saturday (September 2) marked another milestone with the launch of its solar mission, Aditya -L1, also gave us an important update about its moon mission Chandrayaan-3 and said that the Pragyan rover has successfully traversed 100 metres on the lunar surface. Chandrayaan-3 mission update Both Vikram Lander and Pragyan Rover are arguably the two most important components of the country’s lunar mission. In a recent update, ISRO said the latter which is crawling on its six independently movable wheels on the lunar surface has moved 100 metres away from the former. The Indian Space agency after announcing the successful launch of Aditya L-1, on X (formerly known as Twitter) said, “Meanwhile, over the Moon, Pragyan Rover has traversed over 100 meters and continuing.” They also posed an image of the path taken by the Pragyan rover and showed the total traverse distance as 101.4 metres.

Chandrayaan-3: Pragyan rover moves 100 m away from lander, both put to ‘sleep’ as lunar night nears

<p>Within 10 days of having successfully soft-landed Chandrayaan-3 near the Lunar South Pole (and making India the first nation to do so), the Indian Space Research Organisation (ISRO) has launched a craft to study the Sun from afar. As Chandrayaan-3 nears the end of its planned operational life (14 earth days or one Lunar day) and goes to sleep soon, it is now for Aditya-L1 to stay awake and continue on its 125-day journey to the Lagrange Point 1 position, from where it will observe the sun.&nbsp;</p>

<p>Chandrayaan-3 soft-landed on August 23 and the Aditya-L1 mission was placed in its designated elliptical (egg-shaped) orbit around 1:00 pm (local time) on Saturday, August 2. Over the last 10 days, the Chandrayaan-3 lander and rover have been performing in-situ experiments with their respective payloads and sharing the data. However, the end of the Lunar day time is closing in fast on the Vikram Lander and Pragyan Rover. As the duo are solar-powered, they would not be able to function during the fortnight-long Lunar night.&nbsp;</p>

<p>“The Chandrayaan-3 Lander and Rover are functional and our payload teams are doing all th work...The Rover has traversed a distance of 100meters from the lander... In a day or two, we will start the process of putting the lander and rover to sleep, in order to withstand the lunar night (that lay ahead)” Dr S Somanath, Chairman of ISRO, said following the successful launch of the Aditya-L1 solar observatory satellite.&nbsp;</p>

<p>On average, the temperature during the Lunar day could be around 120 degrees Centigrade (For earthlings - that’s much more than the boiling point of water or more than twice the hottest recorded temperatures on Earth). Whereas the Lunar nights could get as cold as -130 degrees Centigrade (that’s almost twice the coldest temperature recorded on the Earth). At the Lunar poles, these temperatures could be even more extreme and hostile.&nbsp;</p>

<p>ISRO hinting that the Chandrayaan-3 lander and rover are to be put to sleep, shows that the Indian space agency has the possible technological means and hope to make Vikram and Pragyan survive the Lunar night. Else, if the mission were to come to an end after the Lunar day, ISRO could have mentioned bidding permanent goodbye to the lander and rover.&nbsp;</p>

<p>By switching off all the on-board equipment and going into hibernation mode and protecting itself from the cold (comparable to covering oneself using a blanket), ISRO could possibly ensure that Chandrayaan-3 survives the Lunar night.</p>

<p>When the Lunar dawn breaks next (around the third week of September), if and when the lander and rover survive, they could again harness the power of the Sun and charge their batteries and continue to carry out their operations. Though a possibility, this could prove a serious bonus to ISRO’s exploratory activities near the Lunar South Pole region, which India temporarily has for itself to explore. However, both the lander and rover have to survive the night for the duo to function normally.&nbsp;</p>

<p>This is because the Lander craft is the primary and direct communication link with the Earth. If the lander cannot communicate directly, it could also use the services of the Chandrayaan-2 orbiter to relay its communications to Earth and receive new commands. However, the 26-kg rover is entirely dependent on the lander to receive commands and carry out communications, and data transfer.&nbsp;</p>

<p>“We are hoping that after the Lunar night it will come back, but it is not assured. This is because, all systems will go to minus 150degrees Centigrade temperature, which is far beyond the survival limit of may materials used on the lander craft. By design it is meant to live for 14days, but if we are lucky, we may get longer,” M. Sankaran, Director of ISRO’s UR Rao Satellite Centre had told WION.<br />
