Why in news?

Indian Space Research Organisation (ISRO) is yet to receive approval from the Indian government for the Venus mission (Shukrayaan) and the mission could, as a result, be postponed to 2031.

More on news:

  • Shukrayaan-I will be a mission for an orbiter. A high-resolution synthetic aperture radar and a ground-penetrating radar are two of its current scientific payloads.
  • From an elliptical orbit, the mission will likely research Venus’s geological and volcanic activities, emissions on the surface, wind speed, cloud cover, and other planetary features.
  • In the budget year 2022–2023, ISRO was given an allocation of 13,700 crores, a small increase from the previous year.
  • Gaganyaan, the human spaceflight mission, received the majority of it.
  • Various industry groups have created a wishlist ahead of the upcoming budget announcement and in response to recent reforms in the private spaceflight sector, which include increases in local manufacturing and procurement.
  • The best time to launch from Earth to Venus is once every 19 months or thereabouts.
  • In case it misses the 2024 window, ISRO has “backup” launch dates in 2026 and 2028.
  • But every eight years, new better windows present themselves that further cut down on the quantity of fuel needed for takeoff.
  • The VERITAS and EnVision missions of the American and European space agencies, respectively, both have Venus missions scheduled for 2031, but “China might go anytime: 2026, 2027, whenever they want to go.
  • The pandemic was mentioned by ISRO as the reason for delaying Shukrayaan I’s launch from mid-2023 to December 2024.
  • Delays in manufacturing and obligations to commercial launch services have also had an impact on other ISRO projects, such as Aditya L1 and Chandrayaan III.
