  • Published
    9th Aug, 2022

The maiden flight of the SSLV or the Small Satellite Launch Vehicle, India’s newest addition to its rocket fleet finally embarked on its first flight recently.

  • The maiden flight suffered a setback, with “data loss” at the terminal stage, after three stages had “performed and separated” as planned.
  • The satellites ended up being placed in an elliptical orbit, and are “no longer usable”.
  • While the three solid fuel-based propulsion stages worked normally, the satellites were injected into a wrong orbit, due to failure of logic to identify a sensor failure.
  • The new rocket was carrying an Indian Earth Observation Satellite, EOS-02, weighing 145 kg and AzaadiSat, made by 750 schoolgirls to celebrate 75 years of Independence under SpaceKidz India, weighing 8 kg.
