PSLVC62 rocket fails to reach orbit, loses DRDO’s ‘supereye’, 15 sats with disruptive technologies

NEW DELHI: Isros PSLV-C62 rocket’s “deviating from its planned flight path” during the launch on Monday is a big setback for not only security agencies that lost crucial defence satellite EOS-N1 (Anvesha) but also several Indian and foreign institutions, startups and companies that lost 15 satellites possessing disruptive technologies that would have brought revolutionary changes in the space sector if they had reached their sun-synchronous orbit home at an altitude of 512 km.

“We attempted the PSLV-C62 EOS-N1 mission. The PSLV is a four-stage vehicle - the first stage is a solid motor with two strap-ons, the second stage is liquid, the third stage is solid, and the fourth stage is liquid. The performance of the vehicle close to the third stage was as expected and as predicted,” Isro chairman V Narayanan said after the botched launch at the Sriharikota spaceport.

“However, near the end of the third stage, we observed some disturbance in the vehicle, and there was a deviation in its flight path. As a result, the mission could not proceed as expected. We are now analysing the data from all ground stations, and once the analysis is complete, we will come back to you,” he said.

DRDOs EOS-N1 (Anvesha), a strategic super-eye, was a hyperspectral imaging satellite capable of “seeing” in hundreds of wavelengths to identify materials on the ground—making it a high-priority asset for national security and surveillance. Had it been placed in orbit, it would have helped India secure its borders through its advanced remote sensing capabilities and would have also seen civilian application in areas such as agriculture, urban mapping and environmental observation.

Last year too, India lost a crucial defence satellite, EOS-09, in space when the PSLV-C61 mission failed on May 18, 2025, due to an anomaly in the third stage, like this time. EOS-09 was an advanced Indian radar imaging satellite designed for all-weather, day-and-night surveillance, crucial for border monitoring, disaster response and resource management.

The PSLV-C62 mission was also carrying KID or Kestrel Initial Technology Demonstrator from a Spanish startup. It was a small-scale prototype of a re-entry vehicle developed by the startup. KID was scheduled to be the last co-passenger to be injected, after which it was slated to re-enter the earth’s atmosphere towards splashdown in the South Pacific Ocean.

Bengaluru-based space startup OrbitAID Aerospace was poised to make history with AayulSAT, India’s first on-orbit satellite refuelling payload. AayulSAT was aimed at extending satellite lifespans by enabling refuelling and servicing in orbit, addressing space debris and sustainability challenges.

Hyderabad startups TakeMe2Space and Eon Space Labs were launching Indias first orbital AI lab. It featured the MIRA telescope and a disruptive model to slash space data costs. Satellite MOI-1 would have taken photos from an altitude of 500 km and also processed them there itself.

Other secondary payloads were cubesats developed by students of several universities and Indian startups, including CV Raman Global Universitys CGUSAT-1, Dhruva Space’s DA-1, Space Kidz India’s SR-2, Assam Don Bosco University’s Lachit-1, Akshath Aerospace’s Solaras-S4 and Dayanand Sagar University’s DSAT-1. All satellites are now lost in space.
