PROSPECT (Package for Resource Observation, in-Situ Prospecting for Exploration, Characterisation & Testing)
ESA drill (ProSEED) and miniature laboratory (ProSPA) package designed to drill beneath the lunar polar surface, extract samples, measure cold-trapped volatiles such as water ice and test oxygen extraction from regolith. It was built for Russia's Luna-27 lander until ESA ended lunar cooperation with Roscosmos in April 2022, when ESA expected a 2025 CLPS flight; it is now assigned to Intuitive Machines' IM-4 flight to Mons Mouton (NASA task order CP-22), which NASA lists for 2027.
Objective. Drill into polar regolith, extract samples and determine the origin and abundance of cold-trapped volatiles; test oxygen extraction from regolith.
This is one payload. It does not inherit the carrier mission's outcome.

Open evidence gaps
- ESA's own PROSPECT pages (esa.int articles and the 2026 video page) returned HTTP 403 on 2026-10-28; the flight assignment was rechecked through NASA pages only.
- Name expansion differs: NASA's CP-22 page uses '... Exploration, Commercial exploitation and Transportation'; ESA's 2026 page uses '... Exploration, Characterisation & Testing'.
- The Open University's payload-builder role is limited to developing/providing the ProSPA instrument as a key subcontractor within the PROSPECT package. It does not establish sole construction, payload ownership or prime contractorship. The 2024 paper names Leonardo as consortium lead; no Leonardo organization profile is added here.

Prospect will reach the lunar surface with the Intuitive Machines' Nova-C lunar lander on the IM-4 mission
The mini lab will also test in-situ resource utilisation, such as oxygen extraction from lunar regolith
We will use PROSPECT and L-CIRiS to help locate nearby chemical compounds that could provide water, oxygen, fuel, and building materials
Intuitive Machines' IM-4 will deliver science and technology to Mons Mouton near the Moon's South Pole
Luna-27 is another lander that was to use the PILOT precision navigation and landing system and deliver the PROSPECT drill and mass spectrometer to find and analyze subsurface water ice and other chemicals.
The drill, being built by Leonardo, will fly on the 2025 CLPS mission
The first utilisation of space resources will be on the Moon; a source of water, oxygen, metals and other materials.
