  • PmL. It measures micro-meteorites and dust
  • LIS-TV-RPM. It is an infrared spectrometry of imaging and minerals
  • STS-L. It is local imaging and panoramic instrument
  • BUNI. It is science data and power support instrument
  • Moon libration, LASER retroreflector and ranging experiments

ESA role in Luna 25

The European Space Agency has been developing a package called PROSPECT for Luna 25. It is to be used for lunar drilling and sample analysis. PROSPECT is Package for Resource Observation and in-Situ Prospecting for Exploration.

Earlier Luna missions

The last of the Luna series was Luna 24 that was launched in 1976. It was the third Soviet Union mission to retrieve lunar surface samples. The first Luna mission was launched in 1970.


Lunar-A was a proposed orbiter of Luna 25 mission. It was to be developed through a merger between Roscosmos and JAXA (Japanese Space Agency). However, the merger was aborted.
