Point of Contact


PROSPECT is a drilling, sampling, sample handling, processing and analysis package under development by the European Space Agency ESA for the Russian Luna-27 mission, scheduled for flight to the lunar south polar region in 2022.

PROSPECT will be operated at the lunar surface in the south polar region of the Moon, where it is required to:

  • Extract samples from depths of more than 1 m.
  • Extract water, oxygen and other chemicals of interest.
  • Identify the chemical species extracted.
  • Quantify the abundances of these species.
  • Characterize isotopes such that origins and emplacement processes of these species can be established.

For more information see the ESA website on PROSPECT.


The PROSPECT (Platform for Resource Observation and in-Situ Prospecting for Exploration, Commercial exploitation and Transportation) instrument package consists of the drilling and sampling system ProSEED (PROSPECT Sample Excavation and Extraction Drill) to collect samples from below the lunar surface and a sample analysis instrument ProSPA (PROSPECT Sample Processing and Analysis) to investigate thermally extracted volatiles.

The Institute of Astronautics at TUM has been involved in the development of ProSPA in the Phase A study  from 2014 to 2015 and the Phase B study from 2016 to 2018. TUM supports the development of the sample ovens that heat the lunar soil sample to extract volatile elements. Several questions regarding heat and mass transfer in the sample, desorption and diffusion of volatiles from the sample, and the overall process of gas extration are adressed, including water extraction and ISRU-like demonstration processes. This involves theoretical analysis and simulation, as well as thermal-vacuum testing and breadboarding in the laboratory. Phase C of PROSPECT is expected to start in early 2019, followed by Phase D and a targeted launch and operation on the lunar surface in 2022.
