EOS-09 or Earth Observation Satellite-09 (formerly known as RISAT-1B) was an Indian Space Research Organisation radar imaging satellite designed to provide continuous and reliable remote sensing data for operational applications across various sectors.[1] It was intended to be a follow on to RISAT-1 satellite with similar configuration. The satellite was developed by the ISRO and was the seventh in the series of RISAT satellites.[2][3][4]
Satellite description
Synthetic Aperture Radar (SAR) can be used for Earth observation irrespective of the light and weather conditions of the area being imaged.[5] It complements/supplements data from Resourcesat, Cartosat and RISAT-2B Series.[6] The satellite carries a C-band synthetic-aperture radar (SAR) and has a liftoff mass of Template:Cvt.[7] The EOS-09 orbit is expected to be in a polar and Sun-synchronous orbit (SSO) at 05:30 AM LTDN, at approximate altitude of 529 km.[8]
Launch Failure
The PSLV-C61 mission launched EOS-9 on 18 May 2025 at 5:59 AM IST. The first and second stages performed nominally, however, the third stage experienced an anomaly which resulted in loss of mission. ISRO is investigating the failure.[9][10]
