Details
editThe PSLV-C51 was launched from the First Launch Pad of the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, India. The PSLV C51 rocket carried primary payload, Amazônia-1 and 18 secondary payloads[7] like SDSat and three UnitySats[11](JITsat, GHRCEsat, Sri Shakthi Sat) etc.
It was the third flight of PSLV-DL,[3] having 2 strap-on boosters and placed the payloads in Sun-synchronous orbits.[12]
Private sector company Ananth Technologies worked with ISRO on the PSLV-C51 mission. The company conducted stage integration and checkout on the mission, marking the first time that ISRO had contracted a private sector company to undertake the task.[13][14]
Launch schedule
editThe launch was originally scheduled for 22 February 2021, but was delayed to 28 February owing to delays in assembly of the rocket.[15]
Mission overview
edit- Propellant:
- Stage 1: Composite Solid
- Stage 2: Earth Storable Liquid
- Stage 3: Composite Solid
- Stage 4: Earth Storable Liquid
- Altitude: 752 kilometres (467 mi)
The PSLV C51 rocket has four stages; each one was self-contained, with its own propulsion system, thereby capable of functioning independently. The first and third stages used composite solid propellants, while the second and fourth stage use earth-storable liquid propellant.
