Human Exploration human spaceflight and operations
OUTLOOK after the CM 2012
MPCV / Orion SM Lunar Lander Lunar Polar Sample Return
EC Workshop Space Science and Exploration Madrid, 18 Feb. 2013
International context human spaceflight and operations
• The Moon remains one of ESA’ s destinations for Exploration.
• The Orion / MPCV Service Module (SM) – approved at the CM 2012 - opens a new perspective for cooperation between ESA and NASA in the area of Human Exploration
• The technology developed in the context of Lunar Lander phase B1 provides options for future cooperation in the area of Lunar Exploration with Russia
EC WS Madrid 18Feb2013 2 MPCV – ORION SM human spaceflight and operations
• ESA will supply the Orion / MPCV SM for the 2017 unmanned Exploration-1 Mission, including ground and flight operation support.
• Provisions for the construction and delivery of a second SM (FM2) are taken.

• As a consequence of the overall economic situation and the need for ESA Member States to set priorities, the Lunar Lander project could not be funded at the CM 2012
• International cooperation provides opportunities for technology validation and extended scientific return: • Surface access & knowledge: Luna-Resource Lander (>2017), • Science and technology: Lunar Polar Sample Return - LPSR (>2020)
• Need to Bridge funding gap to MC 2014: New activities GSTP, GSP

Lunar Polar Sample Return (LPSR) human spaceflight and operations
• Main goal is to bring back frozen samples, rich in volatiles, from the Moon polar regions for analysis in Earth laboratories;
• Ideally samples can be taken from Moon craters, but very low temperatures not compatible with today’s technology for Landing Platform and / or Rover design (even with use of RTGS);
• Frozen samples can be obtained from subsurface drilling (1.5 to 2 m) in illuminated areas. Alternatively samples from shadow areas may be considered; LPSR Technology human spaceflight and operations
• The LPSR mission concept is still evolving, main elements are: a. First Lander with Sample Return Stage b. Second Lander with high mobility Rover
• Main technologies needed by the LPSR missions: – High Thrust propulsion; – RTGS; – Drill and Sample handling – Precision landing – Rover navigation across shadow zones (TBC) – Thermal control of frozen sample on the ascent and return trajectory.
Lunar Polar Sample Return human spaceflight and operations
