The NASA-ISRO joint satellite NISAR will be launched from Satish Dhawan Space Centre, Sriharikota, on July 30 at 5.40 pm, the space agency said on Monday.According to ISRO, GSLV-F16 will inject the Synthetic Aperture Radar (NISAR) satellite into a 743 km Sun-synchronous orbit with an inclination of 98.4 degrees.NISAR will observe Earth with a swath of 242 km and high spatial resolution, using SweepSAR technology for the first time, ISRO said in a release.The satellite will scan the entire globe and provide all weather, day and night data at 12-day interval and enable a wide range of applications, it added.NISAR can detect even small changes in the Earth's surface such as ground deformation, ice sheet movement and vegetation dynamics, according to the space agency.Further applications include sea ice classification, ship detection, shoreline monitoring, storm characterisation, changes in soil moisture, mapping and monitoring of surface water resources and disaster response.NISAR, weighing 2,392 kg, is a unique Earth observation satellite and the first satellite to observe the Earth with a dual frequency Synthetic Aperture Radar (NASA's L-band and ISRO's S-band) both using NASA's 12m unfurlable mesh reflector antenna, integrated to ISRO's modified I3K satellite bus.The NISAR launch is the result of strong technical cooperation between ISRO & NASA/JPL technical teams for more than a decade, the release said.

Harvard Scientist Claims Rare Interstellar Object Might Be "Alien Technology"
A Harvard Scientist claimed that 3I/ATLAS, a rare and mysterious visitor of our solar system, might be a piece of "alien technology". The comet is the third known object ever discovered coming from outside our solar system. Theoretical physicist Professor Avi Loeb told Newsweek that an alien civilisation could have sent the object. The object has been categorised as interstellar because of the hyperbolic shape of its orbital path. It does not follow a closed orbital path about the Sun, NASA explained. The space agency mentioned that the comet is simply passing through our solar system and will continue its journey into interstellar space. "The retrograde orbital plane of 3I/ATLAS around the Sun lies within 5 degrees of that of Earth... The likelihood of that coincidence out of all random orientations is 0.2 per cent," Loeb told the news outlet. 3I/ATLAS was discovered on July 1, 2025, by the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey telescope in Chile. Scientists have estimated that 3I/ATLAS is approximately 10-20 kilometres in diameter, making it the largest interstellar object detected so far. According to Loeb, the brightness of 3I/ATLAS suggests that the object is around 20 kilometres in diameter. He explained that it is "too large for an interstellar asteroid" and "might have targeted the inner Solar System as expected from alien technology". Loeb said that the object lacks features of the comets. "No spectral features of cometary gas are found in spectroscopic observations of 3I/ATLAS," he said. Meanwhile, other scientists are wary of Loeb's claims. Richard Moissl, Head of Planetary Defence at the European Space Agency, told Newsweek: "There have been no signs pointing to non-natural origins of 3I/ATLAS in the available observations." The comet will reach its closest point to the Sun (perihelion) on October 29, 2025, passing just inside Mars' orbit. The astronomers are studying 3I/ATLAS using ground- and space-based telescopes, including the Hubble Space Telescope and the James Webb Space Telescope (JWST), to learn more about its composition, structure, and origin.

Shubhanshu Shukla Shares His Astrophotography Journey: "Over Time We Got Better"
Shubhanshu Shukla, one of the four Indian Gaganyatris who recently returned from the International Space Station (ISS) as part of the Axiom 4 mission, has shared impressive images of the Orion Nebula. Posted on his newly created X (formerly Twitter) account, the photographs were captured from his rooftop in Bengaluru. The images show close-up views of the Orion Nebula, with the Horsehead Nebula clearly visible in the centre. The photographs clicked on the station take some time to received, verified and cleared because of the multiple space agencies involved. While I wait for them I wanted to share an astrophotography story. I started into astrophotography upon returning to India after my first leg… — Shubhanshu Shukla (@gagan_shux) July 24, 2025 Shukla, who is currently undergoing medical evaluations and post-mission recovery, began astrophotography after returning from training in Star City, Russia. He revealed that he often spent free time in the Cupola (a panoramic viewing module on the ISS) capturing views of Earth and outer space. He has promised to release more images and videos taken during his stay in space. These include footage of scientific experiments conducted in microgravity, which ISRO plans to use for educational outreach. The Axiom 4 mission, which included international participation, is seen as a key milestone for ISRO's human spaceflight program, Gaganyaan. The experience gained will support future missions and help ISRO refine its procedures. ISRO is currently preparing for its first uncrewed Gaganyaan flight, expected by the end of 2025, followed by its first crewed mission in 2027.

Over 22 satellite missions launched since 2020: Dr Jitendra
New Delhi, July 24(UNI) Since the announcement of space sector reforms in 2020, India has significantly expanded its capabilities and engagement in space technology, launching a series of satellites, Union Minister for Science & Technology and Earth Sciences Jitendra Singh told the Rajya Sabha today. The satellites launched by India included GSAT-30, EOS-01, CMS-01, Aditya-L1, Chandrayaan-3, XPoSat, and most recently, EOS-09, the minister said in a written reply in the Upper House of parliament. EOS-09 was launched on May 18 to provide reliable remote sensing data. Among the notable scientific missions, Aditya-L1, launched in September 2023, is dedicated to solar studies, while XPoSat (January 2024) marks India's entry into space-based X-ray polarimetry. Chandrayaan-3, launched in July 2023, successfully demonstrated safe lunar landing and rover operations, said the minister. At the same time, over 300 private space start-ups have been registered. The Indian National Space Promotion and Authorisation Centre (IN-SPACe) has facilitated significant private participation, including two successful sub-orbital flights in November 2022 and May 2024, said the minister. A total of 658 proposals have been submitted by more than 380 Non-Governmental Entities (NGEs) across multiple domains such as developmental and disaster mitigation, agriculture & food security, insurance & yield estimation. A semi-physical yield model developed by ISRO for rice and wheat is being implemented under PMFBY for quicker claim settlements in nine states, said the Minister. He also said that satellite imagery supports hazard assessment and damage analysis for floods, cyclones, landslides, earthquakes, and forest fires while in 2024, flood mapping was conducted for 16 states. ISRO also supports early warning systems for Godavari and Tapi rivers. As part of the revised Gaganyaan Programme, approved on October 9, 2024, India is set to pursue a second human spaceflight (H2) following the successful execution of its first crewed mission (H1). The second mission will continue collaborations with existing national and international partners, laying the groundwork for the proposed Bharatiya Antariksh Station (BAS), said the minister.
