| Zusammenfassung |
| Two spacecraft, Luna-Glob and Luna-Resource of Roskosmos (Russia), will be landing on
the lunar south pole in 2016 and 2018, respectively. These spacecraft will carry a complex
scientific payload. Part of the scientific instrumentation is the gas-chromatographic
mass-spectrometric complex, which combines a Thermal Differential Analyser (TDA), a Gas
Chromatograph (GC), and a mass spectrometer (MS). This instrument is dedicated to the
investigation of the volatiles in the lunar soil, its chemical composition, the fraction of water
and organic species, and the identification of noble gases. Measurement of isotopic
composition will be performed of CHON elements (13C/12C, D/H, 17O/16O, 18O/16O,
15N/14N) and noble gases.
We developed a prototype GC-MS instrument for these missions where the GC part is
heritage from the Phobos Grunt mission of Roskosmos and the MS part is a complete new
development for the Luna missions. We have carried out several GC-MS measurements on
calibration gas mixtures that demonstrate that this instrument fulfills the scientific
requirements for the Luna missions. |
