ISRO (Indian Space Research Organization) will launch India’s earth observation satellite, HysIS, along with 30 others on 29 November, from the Sriharikota base, as reported by Hindustan Times (HT). The satellites, 23 of which are from the US, will be launched by ISRO’s reliable rocket, PSLV-C43.
Regarding the HysIS satellite, the space agency said, “the satellite will be placed in 636 km polar sun-synchronous orbit (SSO) with an inclination of 97.957 deg. The mission life of the satellite is five years.”
Satellites in sun-synchronous orbits face the sun at all times, and they mimic the movement of the sun as viewed from the earth. Also, these are placed in space to allow for a constant flow of sunlight, thus helping the solar panels to work continuously. On the other hand, geostationary satellites revolve in the same manner as earth’s rotation on its axis. Therefore, they appear stationary when viewed from the earth.
“The primary goal of HysIS is to study the earth’s surface in visible, near infrared and shortwave infrared regions of the electromagnetic spectrum,” ISRO added.
On Independence Day 2018, PM Modi promised the nation that India will put an Indian into space 2022 becoming the fourth country to have such a capability. The 'Gaganyaan' mission is expected to cost around Rs 10,400 crores.
