The Indian Space Research Organization (ISRO) recently launched the PSLV C52 rocket successfully. The rocket carried two small satellites and EOS 04. The two small satellites were Inspiresat 1 and INS 2TD. This is the first launch of 2022. And it is the first launch since the failure of EOS 03 mission. The EOS 03 failed as the cryogenic upper stage did not ignite.
After 22 minutes of the launch, the fourth stage was passivated. This was done by removing excess propellants. The propellants used were mixed oxides of nitrogen and mono methyl hydrazine. Removing excess fuel is called passivation. Passivation lasted for ten minutes.
It is a radar imaging satellite. It was designed to provide quality image. This includes Forestry, Agriculture-notes-for-state-psc-exams”>Agriculture, flood mapping, moisture, plantations and hydrology. It is to supplement the data from RISAT 2B series, Cartosat and Resourcesat series. The mission life of EOS 04 is ten years. It weighs 1,710 kg.
