Third stage caused ISRO's 101st mission with PSLV-C61 to fail in midair. Setting up EOS-09 in a Sun Synchronous Polar Orbit was the goal

Regarding ISRO's PSLV-C61:

What it is: The PSLV-C61 marked the 63rd mission of the Polar Satellite Launch Vehicle (PSLV) and the 27th in the PSLV-XL variant.

Created by: Indian Space Research Organisation (ISRO).

Mission Aim: To deploy EOS-09, an Earth Observation Satellite, into a Sun Synchronous Polar Orbit (SSPO).

Automobile Characteristics:

Altitude: 44.5 m, Launch Weight: 321 tonnes

Four-stage launch system equipped with six solid rocket boosters.

Phases: Switching between solid and liquid propulsion

Stage 3 Collapse: Pressure in solid motor chamber fell, resulting in mission failure.

Sustainability Initiative: Scheduled Orbit Change Thrusters (OCT) and passivation of PS4 to minimize orbital debris.

Regarding the EOS-09 Satellite:

What it is: EOS-09 is a remote sensing satellite, the successor to EOS-04, designed for various imaging applications across multiple sectors.

Goal:

• Deliver high-resolution, all-conditions Earth imagery through Synthetic Aperture Radar (SAR).
• Assist in disaster observation, farming, forestry, and city planning.

Main Characteristics:

Lift-Off Mass: 1696.24 kg

SAR Payload designed for day/night and all-weather performance.

Mission Duration: 5 years

Supplied with deorbiting fuel for compliance with post-mission disposal regulations.
