PSLV-C61 / EOS-09 Mission

India is set to achieve a significant milestone with the 101st mission of its space programme. On 18 May 2025 at 05:59 AM IST, ISRO will launch EOS-09 aboard the PSLV-C61 from the First Launch Pad (FLP) at Satish Dhawan Space Centre, SHAR . The mission will place the Earth …

EOS-09 (RISAT-1B)

Overview

Destination: Sun-Synchronous Orbit
Mission: Government/Top Secret

Sun-Synchronous Orbit Satish Dhawan Space Centre First Launch Pad Satish Dhawan Space Centre, India

RISAT-1B is the third in the series of radar imaging RISAT-1 satellites of ISRO using an active C-band SAR (Synthetic Aperture Radar), providing all-weather as well as the day-and-night SAR observation capability in applications such as agriculture, forestry, soil moisture, geology, sea ice, coastal monitoring, object identification, and flood monitoring, in addition to military surveillance. The RISAT-1 series is developed, manufactured and integrated by ISRO. The 3-axis stabilized spacecraft bus consists of a hexagonal prism shape build around a central cylinder. Most of the spacecraft subsystems and the payload are integrated in the prism structure and the central cylinder. The solar panels and some subsystems are mounted on the cube-shaped section of the spacecraft.

PSLV-XL

Family:
Configuration: XL

PSLV-XL is the upgraded version of Polar Satellite Launch Vehicle in its standard configuration boosted by more powerful, stretched strap-on boosters with 12 tonne propellant load. Weighing 320t at lift-off, the vehicle uses larger strap-on motors (PSOM-XL or S12) to achieve higher payload capability. On 29 December 2005, ISRO successfully tested the improved version of strap-on booster for the PSLV. The first use of PSLV-XL was the launch of Chandrayaan-1 by PSLV C11. The payload capability for this variant is 1,800 kg to SSO.
