Isro Grounds PSLV Fleet After Launch Failure, Nisar Mission Unaffected
The Indian space agency, Isro, has temporarily stopped using its PSLV rockets after one failed shortly after launch.
This rocket carried a satellite that was supposed to help with things like environmental monitoring and national security, but it didn't make it into space.
The problem happened because of an issue with the third stage of the rocket, which didn't work properly.
Isro is now investigating what went wrong.
Despite this setback, Isro is still preparing for the Nisar mission, a big project with NASA, which will use a different type of rocket.
They're checking everything carefully to make sure future launches, including important crewed missions, go smoothly.
Isro grounded its PSLV fleet after a mission failure.
The PSLV-C61 mission, carrying the EOS-09 satellite, failed due to a third-stage malfunction.
The EOS-09 satellite was lost, which was designed for environmental monitoring and security.
The Nisar mission, a collaboration with NASA, will proceed as planned in June 2025.
An investigation into the PSLV failure is underway, with a report expected by mid-June.
