ISRO’s PSLV-C62 Launch – What Went Wrong and What Happens Next

ISRO’s PSLV-C62 mission experienced onboard anomaly, engineers analyzing Any such failure is valuable input for the scientists as they try to narrow down what exactly went wrong during launch and then try and figure out how to build redundancy into their future spacecraft.
ISRO’s PSLV-C62 Launch - What Went Wrong and What Happens Next

The PSLV-C62/EOS-N1 Mission is the 9th dedicated commercial mission undertaken by NewSpace India Limited (NSIL) to build and launch the EOS-N1 earth observation satellite.

What does two PSLV mission failures in a row mean for ISRO?

At 10:18 a.m., the PSLV-C62, carrying the EOS-N1 satellite and 15 co-passenger satellites created by Indian and foreign startups and academic institutions, launched from the Satish Dhawan Space Centre in Sriharikota following a 22.5 hour countdown.

It is claimed that the EOS-N1 earth observation satellite was constructed for strategic reasons. It is NewSpace India Limited’s (NSIL) commercial endeavor. The KID Capsule will be sent onto a re-entry trajectory and EOS-N1 and 14 co-passenger satellites into a Sun Synchronous Orbit, according to the Indian Space Research Organisation (ISRO).

The PS4 stage will be restarted to de-boost and enter a re-entry trajectory after the injection of EOS-N1 and 14 satellites, and KID capsule separation will come next. According to ISRO, both the PS4 stage and the KID capsule will re-enter Earth’s atmosphere and impact will be in the South Pacific ocean.

Back-to-back PSLV failures for ISRO

When ISRO attempted to launch the EOS-09 satellite on the PSLV-C61 on May 18, 2025, an observation in the rocket’s third stage prevented the mission from being completed.
