Encouraged by high-profile successes elsewhere, India wants its private space companies to increase their share of the global launch market by fivefold within the next decade — an effort boosted by the personal support of Prime Minister Narendra Modi.

In the year after the country opened the way for private launches in 2020, the number of space startups more than doubled, from 21 to 47.

At the end of 2022, Skyroot Aerospace, whose investors include Sherpalo Ventures and Singapore’s GIC, launched India’s first privately built rocket into space.

“Many times initiatives get announced and they die. This is not one of those,” said Pawan Goenka, an auto-industry veteran who last year was named head of Indian National Space Promotion and Authorisation Centre (IN-SPACe), a newly created space regulatory body. “Space is one of the most favourite areas of our prime minister right now, one that he wants to see move.”

Investors poured $119 million (nearly Rs. 980 crore) into Indian space startups in 2022, up from a total of just $38 million (nearly Rs. 312 crore) in all the years up to 2017. They see a less-costly alternative to European launchers that are grounded or under development, as well as access to a bustling manufacturing hub, analysts say.

That has meant a boom for young space companies such as Skyroot and Agnikul Cosmos — which promise to slash launch costs for satellites — Satsure, offering satellite-data and analytics services, and Pixxel, which in March won a five-year contract from the US National Reconnaissance Office.

“It was a big surprise for all of us that the launch and the policy change all happened on time and we were able to meet our deadlines with complete support. We did not have a single day’s delay because of policy issues,” said Pawan Chandana, co-founder of Skyroot, which is valued at $163 million. (nearly Rs. 1,338 crore).

Other startup founders say the new approach means approvals come easier, stakeholders are aligned with each other, and there are more private industry veterans in government helping the sector.

There are challenges, however. The country accounts for just 2 percent of the space sector’s global revenue, estimated at $370 billion (nearly Rs. 30,38,720 crore) in 2020. Funding has only trickled in, as customers want to see successful launches before committing costly payloads to unproven designs.

“There are some very good companies, but at the moment, we are very behind the US or China,” said Prateep Basu, co-founder of SatSure. “Policy unlocking is very important, but the world will not take real notice until you do something remarkable like what SpaceX did.”

In the United States, the government-operated NASA handles space exploration while private companies do launches and build crewed vehicles. Proponents say that has lowered costs, but it also led to a multiyear gap in which Washington relied on Russian space vehicles to travel to the International Space Station.

SpaceX, which serves private customers and governments, conducted more than 60 launches in 2022 alone.

The Indian Space Research Organisation (ISRO) manages all of the country’s launch infrastructure, although Agnikul is planning its own launchpad.

“We realised the industry’s basic need is money,” said Jayant Patil, head of the launch vehicles committee at the Indian Space Association (ISPA), a quasi-government body that helps address private sector concerns.

Patil said the government is offering millions of dollars’ worth of seed funding to startups that use satellite data to boost India’s crop yields. Startups with potential military applications are vetted for government investment separately.

Kanchan Gupta, the Modi government’s senior adviser at the Ministry of Information and Broadcasting, said that the country could not afford to lag behind in the space race, and that “everything cannot be done by the government alone”.

“The whole idea is to provide policy stability, predictability,” Gupta said. “Letting the private sector know where the government comes in, where the government doesn’t come in, where they can get in, where they cannot get in.”

‘Self-sustaining’

The privatisation effort began with a late 2020 video conference call between PM Modi and executives, five people involved in the process say. Since then, PM Modi has made it clear he wants to sweep away red tape and create national champions, they say.

“The prime minister’s aim is to do with space what we have done with IT,” said one of the people, who declined to be named because the call and ensuing meetings were private.

ISRO will focus on exploration but still support private launch efforts, giving the country’s space startups global legitimacy, industry executives said.

The agency will work alongside an advisory panel – with members from In-SPACe, ISPA and NewSpace India Limited (NSIL), the government’s commercial launch arm — that helped the government announce a new, business-friendly regulatory framework in April.

Hindustan Aeronautics and Larsen & Toubro, which helped shape the privatisation policies, have a $100 million (nearly Rs. 821 crore) contract to deliver ISRO’s next launch vehicle in 2024.

“PM Modi is a technology person. So the suggestion is to hand over production and development to private players, while we look at technology. It then becomes a self-sustaining environment,” said S. Somanath, chairman of ISRO.

The country’s space companies also hope to find new customers as sanctions and political tensions have cut off Russia from much of the international launch market after the invasion of Ukraine, which Moscow calls a “special operation”.

The British satellite company OneWeb, for example, partnered with ISRO for a launch after Russia cancelled its launches.

“If you look at high technology, it is a matter of geopolitics… India definitely has some leverage right now,”said Laxman Behera, chairperson at the Jawaharlal Nehru University’s Special Centre for National Security Studies.

Super Earths are Quite Common Outside the Solar System, New Study Reveals

A team of international astronomers, led by Weicheng Zang from the Centre for Astrophysics | Harvard & Smithsonian (Cfa), had announced the discovery of a planet whose size is twice that of Earth, and orbits around its star at a distance farther out than Saturn. These findings reveal how planets differ from our existing solar system. The discovery was first published in the Journal Science on April 25, 2025. Scientists fetched this data from the Korea Microlensing Telescope Network (KMTNet), also known as the largest microlensing survey to date.

This Super Earth, called a planet due to its size being bigger than Earth but smaller than Neptune, is more significant as it is a large study where the masses of many planets have been measured relative to the stars that they orbit. As per physics.org, the team of researchers found fresh information about the number of planets that surround the Milky Way.

Study by KMTNet

According to the study conducted using Korean Microlensing data in which light from faraway objects is amplified through the use of an interfering body, called a planet. This technique is very effective for finding planets at a far distance, between Earth and Saturn’s orbit.

This study is considered to be large for its kind because there are about three times more planets, including planets that are eight times smaller than the previous planets found with the help of microlensing. Shude Mao, a professor, said that the current data gives a hint of how cold planets are formed. With the help of KMTNet data, we can know how these planets were formed and evolved. KMTNet has three telescopes in South Africa, Chile and Australia.

Understanding the Exoplanets

Such studies show that the other systems can have a small, medium and large variety of planets in Earth’s orbit. CFA-led research suggests that there can be more Super Earth Planets in other solar systems’ outer regions. Jennifer Yee says that there is a possibility that outside the Earth’s trajectory, other galaxies may have more such planets that are bigger than Earth’s size yet smaller than Neptune.

Findings and Implications

Youn Kii Jung, who operates KMTNet, says that in Jupiter-like orbits, the other planetary systems may not be similar to ours. Scientists will try to determine how many such planets exist. A study indicates that there are at least as many super-Earths as there are Neptune-sized planets in the universe.

Magnetic Fields Could Significantly Influence Oscillations in Merging Neutron Stars, Study Finds

Magnetic fields may significantly complicate how scientists interpret gravitational wave signals from neutron star mergers, a new study has revealed. These collisions, where two super-dense stellar remnants merge, have long offered astrophysicists a way to probe matter under extreme pressure. The results from the University of Illinois Urbana-Champaign and the University of Valencia reveal that robust magnetic fields form more complex and lengthy patterns in gravitational waves, thereby making it harder to decipher the inner workings of neutron stars. Results could doom post-merger signal interpretation strategies and the equation of states of dense matter as scientists prepare to observe the next generation of gravitational wave observatories.

Magnetic Fields Found to Distort Frequency Signals in Neutron Star Mergers

As per the study published in Physical Review Letters, the researchers simulated general relativistic magnetohydrodynamics — how the strength and arrangement of magnetic fields affect the frequency signals from the remnants left behind after a merger. They went represent real-world conditions by applying two different equations of state (EoS) for neutron stars, different magnetic field configurations, and several mass combinations.

According to lead researcher Antonios Tsokaros, the magnetic field can cause frequency shifts that can misidentify scientists into misattributing them as indications of other physical phenomena like phase transitions or quark-hadron crossover.

The discoveries also imply that scientists need to be cautious about how they interpret signals from neutron-star mergers, lest they slip into assuming how they form. They found that strong magnetic fields can change the emitted signals’ typical oscillation frequency, shifting them from what they should be and from what was predicted by one or another of the competing equations of state at play within these ferocious events.

They also discovered that in the most straightforward type of galaxy mergers they considered in their simulations, the magnetic field became overly amplified so that a greater proportion of the remnants of the merger are more likely to produce further gravitational wave emissions.

Magnetic Fields Hold Key to Unlocking Secrets of Neutron Star Mergers

Neutron stars are what remains of massive stars that have collapsed, and they contain matter so dense that a full teaspoon would weigh billions of tonnes. They have thermodynamic properties that are determined by the EoS and magnetic fields, some orders of magnitude stronger than those that one can produce in a human laboratory.

These extreme features also make neutron stars useful for probing the laws of physics under intense pressure and magnetism. Ever since it was detected in both gravitational waves and gamma rays in 2017, the scientific community has been buzzing about research on neutron star mergers, leading to ever-growing numbers of studies related to these types of mergers.

Professor Milton Ruiz also warns that it would be a mistake to misinterpret observations in the future without considering the effects of the magnetic fields. Higher-resolution simulations are needed, the researchers said, to refine our understanding of how magnetic fields shape cosmic happenings, and endeavours like the Einstein Telescope and Cosmic Explorer loom on the horizon.

Hubble Captures Mars, Cosmic Nebulae, and Distant Galaxies in Spectacular 35th Anniversary Photos

The Hubble Space Telescope is celebrating 35 years in orbit with an amazing batch of new images, including everything from seasonal changes on Mars to a moth-shaped planetary nebula and a distant spiral galaxy. Hubble was deployed from the space shuttle Discovery on April 24, 1990, and has delivered unparalleled cosmic views from low Earth orbit. Its history as a tool for science and exploration has led to nearly 1.7 million observations, more than 22,000 peer-reviewed scientific papers, and about 400 terabytes of archival data. This data has continued to provide generations with glimpses of stunning views of distant and often dynamic universes.

Hubble Reveals Mars and a Celestial Moth in Dazzling 35th Anniversary Image Collection

According to a celebratory statement, officials at the European Space Agency (ESA), which jointly runs Hubble with NASA, lauded the observatory as a way to link the past and future knowledge of the cosmos. As per ESA, the updated slate was announced to celebrate the 35th year of the telescope, during which the instrument has proven it can uncover unseen beauty and detail in the cosmos. “No generation before Hubble ever saw such vibrant and far-reaching images,” ESA officials mentioned in the official blog post.

Among the newly unveiled images is a stunning pair of ultraviolet portraits of Mars taken in December 2023, when the Red Planet was about 60 million miles from Earth. The left image reveals the Tharsis volcanic plateau and Olympus Mons rising through thin water-ice clouds, while the right side captures the “shark fin” shape of Syrtis Major and high-altitude evening clouds, coinciding with spring’s arrival in Mars’s northern hemisphere.

Another image shows a haunting view of NGC 2899, a planetary nebula about 4,500 light-years away in the constellation Vela. Sculpted by a dying star and possibly two stellar companions, the nebula glows with hydrogen and oxygen. Its gaseous tendrils appear to point back toward a pair of white stars at the core, illuminating the violent winds and radiation shaping this celestial moth.

Hubble Captures Star Birth in Rosette Nebula and Distant Spiral Galaxy NGC 5335

In a close-up of the Rosette Nebula — a stellar nursery 5,200 light-years away — dark clouds of gas and dust are seen being carved by radiation from massive stars. A young star at the upper right is actively creating and ejecting jets of plasma, which glow bright red due to shock waves from their collision with surrounding gases.

The image shows a continuing process of star birth in a region spanning four light years, part of a much larger 100-light-year expanse. Hubble also snapped NGC 5335, a barred spiral galaxy found 225 million light-years away in the constellation of Virgo. This flocculent galaxy lacks clear spiral arms, instead featuring patchy bursts of star formation scattered across its disk.

A central bar channels gas inward, supporting new star formation in a galactic dance that astronomers say will continue for billions of years before reshaping again.
