Failing to complete the third stage was the reason the EOS-09 satellite launched by ISRO could not take off properly.
ISRO's EOS-9 Satellite Launch Fails Minutes After Lift-Off
On that same day, the Indian Space Research Organisation experienced a rare problem when the EOS-09 was launched on board PSLV-C61 but did not successfully reach orbit. At 5:59 AM IST, the launch took place from the main space center in Sriharikota.
Mission Overview
EOS-09 was created to boost India’s ability to collect remote images, helping with tasks such as agriculture, forestry, as well as water and disaster management. Using a SAR system, the satellite could obtain images during both daylight and darkness, regardless of weather.
Reasons for the Failure
The Chairman of ISRO, V. Narayanan, noted that the PSLV-C61 performed well during both of its first two stages. During the third stage, the chamber encountered a change in pressure and the mission could not be completed. The reason behind the pressure drop is yet to be identified.
Next Steps
The Department of Space Science and Technology has constituted a Failure Analysis Committee to look into what happened. The team will review and study the data from the telemetry, as well as other related facts, to figure out the reason behind the failure and suggest how to address it for upcoming missions.
ISRO is usually successful, having launched the Chandrayaan-3 mission and the Mars Orbiter Mission with no errors. Even with this failure, the organization keeps pushing for improvements in India’s space sector
