Failure of Luna 25 UPSC NOTE


  • Roscosmos, the Russian space agency, launched Luna 25 spacecraft on August 11.

  • Luna 25 was intended to soft-land near the moon’s south pole, studying lunar soil and atmosphere.

  • On August 20, Roscosmos announced a glitch caused Luna 25 to crash on the moon's surface, marking mission failure.

Purpose of Luna 25 Mission:

  • Luna 25, a part of the Luna series, aimed to secure Russia's access to the moon's surface.

  • It demonstrated Russia's capability in the spaceflight sector and highlighted its role in the International Lunar Research Station (ILRS).

Not in a Race with Chandrayaan 3:

  • Luna 25 and Chandrayaan 3 launched in a similar timeframe, but not in a direct competition.

  • Mission parameters depended on various factors such as launch vehicle, spacecraft mass, trajectory, and pandemic-related delays.

  • Roscosmos had been working on Luna 25 since the early 2010s, while Chandrayaan 3's development began in 2019.

Luna 25's Technical Failure:

  • Roscosmos initiated an investigation to determine Luna 25's failure.

  • Speculation suggests a technical issue during the orbital modification maneuver led to its crash.

  • An engine meant to fire for 84 seconds fired for 127 seconds, causing a deviation from the intended orbit.

Challenges with Communication and Tracking:

  • Due to Russia's actions in Ukraine, it lost access to satellite tracking systems in various countries.

  • Roscosmos could communicate with Luna 25 only over Russia, limiting the time to address the issue.

Implications and Future Prospects:

  • Luna 25's failure indicates Russia's struggle to keep up with lunar exploration.

  • Western sanctions may further limit Russia's involvement in future missions and components imports.

  • The International Lunar Research Station (ILRS) includes plans for Luna missions 26 and 27, but the failure may impact their schedules.

  • Russia's role in the ILRS and lunar exploration might be constrained by its recent setbacks.
