EOS 4

NSSDCA/COSPAR ID: 2022-013A

Description

The 3,770-pound (1,710-kilogram) EOS 4 spacecraft, previously known as RISAT 1A, was expected to next deploy its C-band radar antenna. The spacecraft will collect radar images of Earth, gathering data useful in agriculture, soil moisture detection, disaster management, disaster assessment, carbon inventory, and forestry and plantation management.

The mission aimed for a polar orbit 328 miles (529 kilometers) above Earth. ISRO officials also confirmed the main satellite on the launch, named EOS 4, deployed its solar panels to begin generating its own electrical power.

Radar remote sensing satellites can see Earth’s surface in day and night, and aren’t obscured by cloud over like optical imaging missions. EOS 4 is beginning a 10-year mission.
