Sriharikota: The launch of the Indian Space Research Organization (ISRO) PSLV-C61, which aims to deploy EOS-09 Earth observation satellite On Sunday, a Sun-Synchronous Polar Orbit from the first launch pad at the Satish Dhawan Space Center (SDSC) failed.The chairman of ISRO said, “The launch vehicle performed normal till the second phase and they made an observation in the third phase. The mission could not be completed. We will return after analysis.”The previous PSLV mission which failed, was the PSLV-C39 mission to deploy IRNSS-1H navigation satellite on 31 August 2017. The mission failed due to a malfunction heat shield.This is the third failure of PSLV. The first failure PSLV-D1 was launched on September 20, 1993.“The 101st launch was attempted today, the PSLV-C61 performance was normal to 2 stages. Due to an observation in the 3 phase, the mission could not be completed,” ISRO posted on X.The 44.5-meter long PSLV-C61, the weight of 321 tons in the liftoff increased in the sky at 5.59, which took 1696.24 kg EOS-09 (Earth observation satellite-09). The mission was important for several reasons – this was the 63rd overall flight of PSLV, and the 27th was known to carry heavy payloads using its XL configuration.EOS-09 Risat-1 is a radar imaging satellite configured using a heritage bus and is equipped with one Synthesis aperture radar (Sir). This all-visitor imaging capacity increases India’s Earth observation assets by supporting a wide range of applications including agriculture, forestry, soil moisture estimates and disaster management. The EOS-09 is essentially an follow-up to the first EOS-04, which aims to improve image acquisition frequency and data continuity for operating users.
