<p>Since 2020, India has seen significant growth in the number of space sector startups. It is a direct result of the Indian Government introducing reforms that permitted private firms to carry out all space activities, including the building and launching of privately-developed rockets and satellites, providing space-based services etc.</p>

<p>Today, India has nearly 200 space sector startups, all of whom are operating in a capital-intensive, high-risk, low-return domain, which is dominated by India's Government-run Indian Space Research Organization(ISRO). In order to support such nascent firms, the Indian Union Budget has allocated Rs.1000cr(approx $120mn) as a Venture Capital Fund for space startups. Finance Minister Nirmala Sitaraman announced that the Indian government will set up a Rs.1,000 crore venture capital fund to finance the space economy.</p>

<p>Welcoming the announcement, Lt. Gen. AK Bhatt (Retd.), Director General, of the industry body Indian Space Association (ISpA) said, "The proposal for establishment of 12 industrial parks across India we hope will include the space sector, as this will provide a substantial boost to the space and satellite manufacturing industry, which has long called for the creation of space parks. These measures are pivotal for the growth and development of India's space ecosystem."</p>

<p>Astronomers have for the first time spotted a neutron star releasing a weird S-shaped jet, which looks like a "garden sprinkler".&nbsp;</p>

<p>As per scientists, the S-shaped structure is created when the jet's direction changes because of the wobbling of the disk of hot gas near the star in a process known as precession.</p>

<p>However, till now this process has been observed with&nbsp;black holes and never with&nbsp;neutron stars.&nbsp;</p>

<p>The neutron star is present in the&nbsp;binary system&nbsp;Circinus X-1 which is more than 30,000 light-years from Earth.</p>

<h2><strong>Here's why the S-shaped jet is getting released from star</strong></h2>

<p>The birth of this star took place when a star which was nearly eight times the size of the sun died in a&nbsp;supernova explosion.&nbsp;</p>

<p>The light from this supernova explosion is likely to have reached Earth around 5,000 years ago. The neutron star is said to have been devouring its companion star and behaving like a&nbsp;cosmic vampire which is causing an eruption of high-energy jets from it.</p>

<p>These jets take the shape of S because the vampire dead star is wobbling or "precessing" similar to a spinning top when it feeds.&nbsp;</p>

<p>The team of scientists who have carried out the research believe that this is a first-of-its-kind observation which can help them better understand the&nbsp;extreme physics among neutron stars.</p>

<p>"This image is the first time we have seen strong evidence for a precessing jet from a confirmed&nbsp;neutron star," said team leader Fraser Cowie, a researcher at Oxford, in a statement.&nbsp;</p>

<p>"This evidence comes from both the symmetric S shape of the radio-emitting plasma in the jets and from the fast, wide shockwave, which can only be produced by a jet changing direction," he added.</p>

<p>World's first study on common food aromas may help scientists understand why astronauts report that meals taste bland in space even as they struggle for their normal nutritional intake.&nbsp;</p>

<p>Scientists from RMIT University have led a study, which was published on Tuesday (Jul 16) in the International Journal of Food Science and Technology.&nbsp;</p>

<p>"Previous astronauts or space travellers have reported that food doesn’t taste the same in space as it does on Earth," first author Grace Loke, a PhD candidate at RMIT, told COSMOS.&nbsp;</p>

<p>"Imagine having your meals pre-planned months ahead because they tasted good on Earth, only to dislike them in space. Usually, flavour is lost," Loke added.&nbsp;</p>

<p>This research serves the purpose of how changes can be implemented in order to improve the diets of isolated people. Not just astronauts, the research might help people including nursing home residents by personalising aromas to enhance the flavour of their food.&nbsp;</p>

<p>For the study, the researchers examined how the participants perceived&nbsp;vanilla and almond extracts. They also studied how lemon essential oil changed from everyday Earth settings to the conditions on the International Space Station (ISS).&nbsp;</p>

<p>As quoted by phys.org, lead researcher Dr Julia Low from the School of Science said vanilla and almond aromas were more intense in the ISS-simulated environment. Meanwhile, the lemon scent remained unchanged.&nbsp;</p>

<p>According to the researchers, benzaldehyde, which is a sweet chemical in the aromas of vanilla and almond, could explain the change in perceptions. Besides, an individual's sensitivity to a particular smell can also be the reason.&nbsp;</p>

<p>"A greater sense of loneliness and isolation may also play a role, and there are implications from this study around how isolated people smell and taste food," Low said.</p>

<p>The study involved a&nbsp;sample size as it included 54 adults. "One of the long-term aims of the research is to make better tailored foods for astronauts, as well as other people who are in isolated environments, to increase their nutritional intake closer to 100%," Low said.&nbsp;</p>

<p>The researchers also studied the phenomenon of fluid shift and complemented results from other studies based on eating experiences in space.&nbsp;</p>

<p>The study mentioned that fluid moves from the lower to the higher regions of the body while one is weightless, causing swelling in the face and congestion in the nose. This eventually impacts taste and smell. However, these symptoms vanish a few weeks after entering the space station in most cases.&nbsp;</p>

<p>"Astronauts are still not enjoying their food even after fluid shift effects have gone, suggesting that there's something more to this," Low said.</p>

<p>A new definition of what a planet is, has been proposed by planetary scientists to replace the one which already exists, and is seen as outdated and sun-centric by many experts.&nbsp;</p>

<p>It has been taught to us from school days that Earth orbits around the Sun, which results in the cycle of day and night.&nbsp;</p>

<p>However, if we try to understand the movement of Earth currently in the Solar System from the point of view of scientists,&nbsp;our planet is not currently orbiting the Sun.</p>

<h2><strong>So, what's happening between Earth and the Sun?</strong></h2>

<p>In the Solar System, the Sun is the largest object and has 1,048 times the mass of Jupiter. However, the gravitational pull which Earth exerts on the celestial body is exerted in the same or smaller amount on the planet.</p>

<p>"Kepler's third law describes the relationship between the masses of two objects mutually revolving around each other and the determination of orbital parameters,"&nbsp;explained NASA.</p>

<p><strong>Also Read:</strong>&nbsp;<a href="https://www.wionews.com/science/house-for-astronauts-indian-startup-discusses-launch-of-space-habitat-by-2027-with-spacex-739929">House for astronauts? Indian startup discusses launch of 'space habitat' by 2027 with SpaceX</a></p>

<p>"Consider a small star in orbit about a more massive one. Both stars actually revolve about a common centre of mass, which is called the&nbsp;barycentre. This is true no matter what the size or mass of each of the objects involved. Measuring a star's motion about its barycenter with a massive planet is one method that has been used to discover planetary systems associated with distant stars," it added.</p>

<p>So, Earth orbits a barycentre and not exactly the Sun. Generally, the barycentre of the bodies in the Solar System is near the Sun, however, because of the mass, and influence of gas giants Jupiter and Saturn and orbits, it is rarely inside the Sun.&nbsp;</p>

<h2><strong>Where is the barycentre currently?</strong></h2>

<p>Currently, the barycentre is outside the Sun and not inside it and hence, Earth is not currently orbiting it. So, the planet is revolving around a point in space and not the Sun.&nbsp;</p>

<p>Explaining this positioning of the planet, planetary astronomer and science communicator&nbsp;James O'Donoghue said, "Planets orbit the Sun in general terms", "but *technically* they don't orbit the Sun alone because the gravitational influence of (mainly) Jupiter means planets must orbit a new point in space."</p>

<p>"The planets do orbit the Sun of course, we are just being pedantic about the situation," he&nbsp;added.

It has been taught to us from school days that Earth orbits around the Sun, which results in the cycle of day and night. However, if we try to understand the movement of Earth currently in the Solar System from the point of view of scientists, our planet is not currently orbiting the Sun.

It has been taught to us from school days that Earth orbits around the Sun, which results in the cycle of day and night. However, if we try to understand the movement of Earth currently in the Solar System from the point of view of scientists, our planet is not currently orbiting the Sun. So, what's happening between Earth and the Sun? In the Solar System, the Sun is the largest object and has 1,048 times the mass of Jupiter. However, the gravitational pull which Earth exerts on the celestial body is exerted in the same or smaller amount on the planet. "Kepler's third law describes the relationship between the masses of two objects mutually revolving around each other and the determination of orbital parameters," explained NASA. Also Read: House for astronauts? Indian startup discusses launch of 'space habitat' by 2027 with SpaceX "Consider a small star in orbit about a more massive one. Both stars actually revolve about a common centre of mass, which is called the barycentre. This is true no matter what the size or mass of each of the objects involved. Measuring a star's motion about its barycenter with a massive planet is one method that has been used to discover planetary systems associated with distant stars," it added. So, Earth orbits a barycentre and not exactly the Sun. Generally, the barycentre of the bodies in the Solar System is near the Sun, however, because of the mass, and influence of gas giants Jupiter and Saturn and orbits, it is rarely inside the Sun. Where is the barycentre currently? Currently, the barycentre is outside the Sun and not inside it and hence, Earth is not currently orbiting it. So, the planet is revolving around a point in space and not the Sun. Explaining this positioning of the planet, planetary astronomer and science communicator James O'Donoghue said, "Planets orbit the Sun in general terms", "but *technically* they don't orbit the Sun alone because the gravitational influence of (mainly) Jupiter means planets must orbit a new point in space." "The planets do orbit the Sun of course, we are just being pedantic about the situation," he added. "The natural thinking is that we orbit the Sun's centre, but that very rarely happens, i.e. it's very rare for the solar system's centre of mass to align with the Sun's centre," he added.

<p>To make a mark in the world of space science, China has now planned to strike an asteroid to deflect it by 2030, on the pretext of planetary defence.&nbsp;</p>

<p>The scientists have said that the mission has a dual purpose - the asteroid will be impacted by one spacecraft and its partner will make observations of the space rock to understand more about the solar system and its formation.</p>

<p>As per the reports, the&nbsp;near-Earth object&nbsp;(NEO) 2015 XF261 - which is a 100-foot-wide (30-metre)&nbsp;asteroid - is most probably the selected target of the China National Space Administration&nbsp;(CNSA) mission.</p>

Also Read: Astronauts hide in space station after defunct Russian satellite breaks into more than 100 pieces How are these Northern Lights created? Explaining the phenomena, the ISS wrote, “These spectacular light shows occur when charged particles from the Sun collide with Earth’s magnetosphere. The result is glowing auroras that are constantly moving, creating an array of bands that fold, swirl, and ripple." “While often spotted from the ground near the Northern and Southern Hemispheres, the orbiting laboratory’s unique vantage point gives low Earth orbit crews a front-row seat to the colourful spectacle,” the space station added. Since the video was shared, it received more than 4.7 lakh views and over 34,000 likes. Several comments were made by the people on the post. Here's how the netizens reacted to the video “These views never get old,” wrote an Instagram user. “Truly the most beautiful, jaw-dropping feature in nature to witness," added another.

Cyprus' sci-fi wonder and gateway to the stars

<p>A new theoretical research has made a stunning revelation that the Earth is currently crossing an ocean of&nbsp;dark matter and this&nbsp;invisible ocean's waves have been slamming against the upper atmosphere of our planet and generating detectable radio waves.&nbsp;</p>

<p>As per the research, these detectable radio waves have been helping in finally finding this universe's elusive component.</p>

<p>A lot of astrophysical and cosmological evidence, like certain galaxies' inexplicable rotation curves and the largest structures' growth in the cosmic space, has pointed towards the dark matter's existence.&nbsp;</p>

<p>The attempts made to explain these observations with alternative formulations of&nbsp;gravity&nbsp;have not succeeded. Astronomers currently believe that dark matter is some kind of matter which only rarely interacts with normal matter or light.</p>

SpaceX to receive $843 million contract from NASA to destroy the International Space Station

A dangerous situation similar to that of the Hollywood film "Gravity" unfolded in space. Pieces of space debris in the vicinity of the International space station posed a threat. All 9 astronauts on-board had to take shelter, bracing for possible impact. Here's how it all unfolded.

Gravitas | Defunct Russian satellite generated space debris, threatening astronauts, space station

A defunct Russian satellite has broken up into more than 100 pieces of debris in orbit, forcing astronauts on the International Space Station to take shelter for about an hour and adding to the mass of space junk already in orbit, U.S. space agencies said.

Russian satellite breaks up in space, astronauts take over

<p>In what is the most significant commercial space sector partnership between India and Australia, the Indian Space Agency would be launching a satellite built by an Australian firm. Interestingly, this mission 'Space MAITRI' (Mission for Australia-India's Technology, Research and Innovation) would be performed by India's smallest and newest rocket SSLV, and the passenger would be Australia's biggest satellite the 450kg 'Optimus'. The commercial pact for this launch, scheduled to take place in 2026, has been made between ISRO's commercial arm - NewSpace India Limited(NSIL) and the Australian firm Space Machines Company.&nbsp;</p>

<p>The Optimus satellite is a unique piece of hardware, which is meant to perform in-orbit inspection of other satellites and even perform certain kinds of repair work. "Once Optimus gets into earth orbit, it will put itself in park-mode, and await its next mission. If any satellite in orbit breaks down, the operators(of the broken down satellite) will call Space Machines, who will then move Optimus towards the broken down satellite, inspect it and diagnose the issue," Space Machines Company says.&nbsp;</p>

<p>Based on the inspection performed by Optimus, the operators of the malfunctioning satellite can be made aware of the exact technical issues faced by the craft. As this technology further evolves, Optimus satellites can also perform in-orbit repairs, refuelling, and even safe disposal of satellites that have completed their life cycle. By performing repairs and re-fuelling of satellites, it is possible to considerably extend the operational life of satellites and reduce the rapid proliferation of space debris.&nbsp;</p>

<p>"This collaboration with Space Machines Company exemplifies the spirit of international cooperation in space and highlights the strategic partnership between Australia and India," said Radhakrishnan Durairaj, Chairman and Managing Director, NSIL. This mission marks a significant milestone in the strategic partnership between Australia and India in the space domain, fostering closer ties between commercial, institutional, and governmental space organisations from both nations.</p>

The commercial pact for this launch, scheduled to take place in 2026, has been made between ISRO's commercial arm - NewSpace India Limited(NSIL) and the Australian firm Space Machines Company. The Optimus satellite is a unique piece of hardware, which is meant to perform in-orbit inspection of other satellites and even perform certain kinds of repair work. "Once Optimus gets into earth orbit, it will put itself in park-mode, and await its next mission. If any satellite in orbit breaks down, the operators(of the broken down satellite) will call Space Machines, who will then move Optimus towards the broken down satellite, inspect it and diagnose the issue," Space Machines Company says. Also Read: ALMA telescope sheds light on planet formation around binary stars Based on the inspection performed by Optimus, the operators of the malfunctioning satellite can be made aware of the exact technical issues faced by the craft. As this technology further evolves, Optimus satellites can also perform in-orbit repairs, refuelling, and even safe disposal of satellites that have completed their life cycle. By performing repairs and re-fuelling of satellites, it is possible to considerably extend the operational life of satellites and reduce the rapid proliferation of space debris. "This collaboration with Space Machines Company exemplifies the spirit of international cooperation in space and highlights the strategic partnership between Australia and India," said Radhakrishnan Durairaj, Chairman and Managing Director, NSIL. This mission marks a significant milestone in the strategic partnership between Australia and India in the space domain, fostering closer ties between commercial, institutional, and governmental space organisations from both nations.

By combining our innovative spacecraft capabilities with India's proven launch expertise, we are not only strengthening the ties between our nations' space sectors but also demonstrating our shared commitment to sustainable space operations," said Rajat Kulshrestha, CEO and Co-Founder of Space Machines Company. The 'Space MAITRI' mission involves several Australian and Indian partner companies collaborating with Space Machines Company, including Digantara, Ananth Technologies, The University of Adelaide, The University of Sydney, The University of Technology Sydney, LeoLabs, Advanced Navigation, and the Australian Strategic Policy Institute (ASPI).

Giant leap for Ind-Aus ties: ISRO to launch biggest Australian satellite

<p>A space scare occurred when a defunct Russian satellite broke up into more than 100 pieces of debris within its orbit which led to the astronauts taking shelter on the&nbsp;International Space Station for about an hour, stated the US space agencies.</p>

<p>They added that the mass of space junk is already present in orbit. No information was provided on what led to the breaking of the Resurs-P1 Russian Earth observation satellite. This satellite was declared dead by Russia in 2022.</p>

<p>While tracking the swarming debris, US Space Command said that other satellites did not face any other immediate threat.</p>
