ISRO’s PSLV-C62 mission fails during third stage, 16 satellites lost

Published by Webster

The Indian Space Research Organisation’s (ISRO’s) polar satellite launch vehicle (PSLV)-C62 rocket, carrying 16 satellites including a foreign earth observation satellite, “encountered an anomaly” on Monday, the space agency said, signalling the failure of the mission. Disturbances were observed in the rocket during the third stage, while the strap-on motors were providing thrust to propel the vehicle to its intended altitude, ISRO Chairman V Narayanan said, adding that a detailed analysis has been initiated to identify the cause. The rocket later deviated from its flight path, preventing the satellites from being placed in the intended orbit, news agency PTI reported. According to ISRO sources, all 16 satellites were lost in space. This marks the second consecutive PSLV mission failure during the third stage. A similar mission in May 2025 (PSLV-C61/EOS-09) also failed due to a “motor pressure issue,” which caused a drop in the chamber pressure of the motor case. The 44.4-metre tall, four-stage rocket lifted off as scheduled at 10.18 am from Sriharikota, after a 22.5-hour countdown. The mission aimed to deploy a primary …

ISRO’s PSLV-C62 will carry EOS-N1 and 15 co-passenger satellites (ISRO) The Indian Space Research Organisation (ISRO) will on Monday launch the PSLV-C62 mission, marking the first space mission of India’s 2026 launch calendar. The Polar Satellite Launch Vehicle will lift off from the First Launch Pad at the Satish Dhawan Space Centre in Sriharikota, carrying the EOS-N1 earth observation satellite along with 14 co-passenger satellites for domestic and international customers. The mission, undertaken by NewSpace India Limited (NSIL), the commercial arm of ISRO, is the ninth dedicated commercial mission executed by NSIL. It also marks the 64th flight of the PSLV, which continues to serve as ISRO’s workhorse launch vehicle. According to ISRO, the PSLV-C62 is a four-stage launch vehicle, standing 44.4 metres tall with a lift-off mass of 260 tonnes. The mission uses the PSLV-DL configuration, equipped with two solid strap-on motors. The …

ISRO’s ‘Bahubali’ LVM3 vs SpaceX’s Falcon 9: Can India Beat Elon Musk On Space Economics? | India News

Published by Webster

Last Updated:December 25, 2025, 14:37 IST ISRO’s LVM3 can carry roughly 8-10 tonnes to low-Earth orbit (LEO) and Wednesday’s mission, at 6,100kg, marked one of its heaviest commercial payloads SpaceX routinely lands and refurbishes its boosters but LVM3 is still expendable as each rocket is used once and discarded. (AP/PTI) The Launch Vehicle Mark-III (LVM3), often dubbed as India’s heaviest rocket and ISRO’s ‘Bahubali’, roared off the pad at Sriharikota early on Wednesday, December 24, placing a 6,100kg US communications satellite, ‘Blue Bird’, into orbit. The success has once again ignited the long-running debate over who really rules the global launch market on cost; India’s space agency ISRO or Elon Musk’s SpaceX. On one side stands ISRO, celebrated for its frugal engineering and ‘jugaad’ mindset. On the other is SpaceX, which has rewritten the economics of spaceflight through reusable rockets. With both players now competing for the booming commercial launch market, the question is simple: whose ride is cheaper? SpaceX’s Falcon 9 is by far the world’s busiest rocket. Various reports peg the cost of …

These additions were confirmed by the International Astronomical Union India now has seven new references marked on Martian soil, with several well-known places from Kerala earning a place on the Red Planet’s geological map. Kerala’s largest river, its biggest fort, a famed beach, and two towns linked to India’s space journey now share their names with features located nearly 225 million kilometres away. These additions were confirmed by the International Astronomical Union (IAU) on November 24. The latest naming list includes Periyar, Bekal, Varkala, Thumba and Valiamala. These names have been assigned to craters, valleys and plains identified during recent planetary mapping. Two other features on Mars also honour eminent Indian geologist MS Krishnan, the first Indian to head the Geological Survey of India in 1951.

(File image/ISRO) The Indian Space Research Organisation (ISRO) has achieved a critical safety milestone for the Gaganyaan mission, successfully completing a key Integrated Main Parachute Airdrop Test (IMAT) for the Crew Module’s deceleration system. This successful qualification test, conducted at the Babina Field Firing Range (BFFR) in Jhansi, Uttar Pradesh, on November 3, 2025, is a major step towards ensuring the safe return of Indian astronauts (Vyomanauts). Testing for Extreme Scenarios The test focused on validating the parachute system’s structural integrity and load distribution under a highly critical failure condition: asymmetric disreefing. This scenario simulates a delay in the full opening of one of the main parachutes.
