ISRO Chairman V. Narayanan announced on August 1, 2025, that the failure analysis for the PSLV‑C61 mission carrying EOS‑09 has been completed, describing the anomaly as “small.” The mission, launched on May 18 at 05:59 AM IST from Sriharikota, failed when a pressure drop occurred in the third-stage PS3 motor, preventing satellite deployment. A National Failure Analysis Committee had been convened shortly after to investigate the root cause. The final report is expected to be formally submitted to the Prime Minister in the coming days.

Two Indian scientists — aerospace engineer Rahul Mogalapalli and astrobiologist Yaman Akot — have begun a 10-day isolation mission inside a specially designed space habitat named HOPE (Human Outer Planet Exploration), located near Tso Kar in Ladakh at over 14,500 feet altitude. Built by ProToPlanet with ISRO's support, the dome mimics Martian conditions to test physical and psychological endurance required for interplanetary missions. The extreme altitude, oxygen scarcity, and rugged terrain resemble space-like challenges. Data from this mission will help refine astronaut training and support India's ambitions in future space exploration. (PC: The Print)

Following the successful launch of the NASA‑ISRO Synthetic Aperture Radar satellite, ISRO is preparing to launch the next U.S. collaboration: the BlueBird Block 2 communications satellite, developed by AST SpaceMobile. This mission will utilize ISRO’s LVM3 heavy‑lift rocket to deploy the satellite into low Earth orbit . Announced by ISRO Chairman V Narayanan, it is one of nine major launches planned before the current fiscal year ends . BlueBird Block 2 promises vastly expanded cellular broadband capacity with approximately ten times the bandwidth of the prior Block 1 satellites. (PC: PTI)  

A mysterious interstellar object named 3I/ATLAS, discovered in July 2025, is set to pass within 130 million miles of Earth on October 30, sparking global intrigue. While NASA classifies it as a comet, Harvard astrophysicist Avi Loeb theorizes it could be alien technology, possibly even hostile. Loeb’s paper suggests the object’s unusual trajectory and retrograde orbit may indicate intelligent design, with potential for stealth maneuvers while hidden behind the Sun. Though most scientists dismiss the theory, Loeb insists it’s a testable hypothesis worth exploring. The object’s size over 12 miles wide and speed have intensified debate over extraterrestrial surveillance and the need for planetary defense readiness. (PC: Evidence Network & India Today)

On July 30, 2025, Gilmour Space Technologies launched Eris Testflight 1 from the Bowen Orbital Spaceport in Queensland—Australia’s first domestically built orbital rocket launch attempt . The 23‑meter rocket achieved 23 seconds of engine burn and 14 seconds of flight before crashing northeast of the pad in a plume of smoke—without injuries or damage to infrastructure . CEO Adam Gilmour hailed the mission as “a strong result,” noting that all four hybrid engines ignited successfully and the launch provided vital data for future rockets . Plans include a second test flight within six to seven months as the company advances Australia's sovereign space capability.

On July 30, 2025, ISRO launched the $1.5 billion NISAR satellite aboard GSLV-F16, making it the world’s most expensive Earth-imaging satellite. Jointly developed with NASA, NISAR combines L-band (NASA) and S-band (ISRO) radar, becoming the first satellite to use dual-band synthetic aperture radar. It will orbit in a sun-synchronous path, scanning Earth every 12 days to monitor land changes, glacier melt, forest loss, and disasters with centimeter-level precision. With a five-year mission life, NISAR will significantly aid climate research, environmental monitoring, and disaster response across the globe.  

Launched on July 30, 2025 via ISRO’s GSLV‑F16 from Sriharikota, the NASA‑ISRO Synthetic Aperture Radar (NISAR)—a $1.5 billion mission—is the world’s first radar satellite to use dual-frequency sensors (NASA’s L‑band & ISRO’s S‑band). The “two‑eyed” payload enables it to map nearly all land and ice surfaces every 12 days, detecting changes down to a centimeter, day or night, through clouds and vegetation . Over its planned three‑year mission, NISAR will revolutionize monitoring of earthquakes, glacier melt, deforestation, landslides, infrastructure stability, agricultural patterns and more—delivering open-access data to scientists, policymakers, and disaster responders worldwide. 

On July 30, 2025, the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite was launched aboard India’s GSLV-F16 rocket from the Satish Dhawan Space Centre. Marking the first collaboration of its kind between NASA and ISRO on Earth observation, the mission aims to monitor minute shifts in the Earth’s surface—including landslides, earthquakes, glacial melt, and soil moisture—using advanced dual-frequency radar technology. NISAR will scan the Earth every 12 days, providing free and high-resolution data globally. This mission is a major step in understanding climate change, natural disasters, and land-use patterns with unprecedented accuracy. (PC: ISRO)

India successfully launched the NISAR satellite—a $1.5 billion joint mission between ISRO and NASA—on July 30 from Sriharikota. NISAR (NASA-ISRO Synthetic Aperture Radar) is the world’s first Earth-mapping satellite using dual-frequency radar, capable of detecting Earth’s slightest shifts and changes every 12 days. Weighing 2,393 kg, it will orbit the planet every 97 minutes, aiding global disaster response, glacier tracking, and climate monitoring. The mission, a decade-long collaboration, marks a major leap in space-tech and environmental science. With near real-time, free data, India strengthens its leadership in global climate action and scientific cooperation. 

The joint ISRO-NASA Earth observation satellite NISAR has successfully launched from the Satish Dhawan Space Centre in Sriharikota aboard India’s largest rocket, the GSLV Mk II. The 2,392 kg satellite will enter an 8–10 day deployment phase followed by 65 days of engineering tests. NISAR, equipped with L-band (NASA) and S-band (ISRO) synthetic aperture radars, will map Earth's surface every 12 days with high precision, detecting even slight movements. The mission, 10 years in the making, will help monitor earthquakes, landslides, and climate change, with special focus on Antarctica and global vegetation. Former ISRO chief K Sivan called it “a breakthrough.”
