EXOMARS ROVER MODULE Thermal Control System

2008-06-29
2008-01-2003
EXOMARS is a European-led space exploration mission, currently under development by the European Space Agency (ESA) that will send a robotic rover to the surface of Mars. The EXOMARS rover is a “robotic mission” which will provide Europe with new technologies for the exploration of Mars, specifically the surface Rover and its Drill and Sample Preparation and Distribution System (SPDS). ...The scientific payloads are accommodated in two separate assemblies: the Pasteur Payload installed onboard the Rover, and the Geophysical Science Package, mounted on the Landing Platform. The Rover accommodates as well a drill capable of collecting soil samples down to 2 m below the Mars surface. ...The EXOMARS rover is a “robotic mission” which will provide Europe with new technologies for the exploration of Mars, specifically the surface Rover and its Drill and Sample Preparation and Distribution System (SPDS). The EXOMARS spacecraft will be launched from the Guiana Space Centre (Kourou) in 2013: it will consist of the Carrier Module (CM) and a Descent Module (DM).

The Mars Exploration Rovers (MER), were launched in June and July of 2003, respectively, and successfully landed on Mars in early and late January of 2004, respectively. ...The flight system architecture implemented many successful features of the Mars Pathfinder (MPF) system: A cruise stage that transported an entry vehicle that housed the Lander, which in turn, used airbags to cushion the Rover during the landing event. The initial thermal design approach focused on adopting the MPF design wherever possible, and then concentrating on the totally new Rover thermal design. ...The initial thermal design approach focused on adopting the MPF design wherever possible, and then concentrating on the totally new Rover thermal design. Despite a fundamentally sound approach, there were several salient lessons learned.

981530
The combination of electrical engines with solar arrays, well shielded against radiation long-term LSS, and remote control robot-manipulator system named “Space Rover” is shown to be very promising tool for space exploration. General parameters of space ship based on already developed components, and parameters of flight are considered.

Neck-Entry Suitports: A Novel Concept Utilizing Morphing Upper Torso Technology

This paper describes a unique concept for donning and doffing a spacesuit from a pressurized rover or habitat, which merges three independent concepts: suitports, neck-entry EVA suits, and the Morphing Upper Torso. ...To develop this concept, a neck-entry Morphing Upper Torso experimental model has been designed and fabricated, and systems level design studies have been performed, including visualization with the aid of CAD models of the neck-entry suitport on a small pressurized rover and a lunar habitat. As well, a donning test-station has been developed and used for experiments in 1-G, simulated microgravity and simulated partial gravity. ...Together with the CAD models and the experimental pressurized Morphing Upper Torso model, the experiments have shown that this concept should be considered for a future suitport and suit architecture, which could greatly simplify the suitport design, minimize volume needed within the rover or habitat, improve PLSS design and servicing, and simplify suit alignment with the suitport during egress from the suit.

CAD-Based Stand-Alone Spacecraft Radiation Exposure Analysis System: An Application of the Early Man-Tended Space Station

1993-09-01
932557
This improved shielding analysis technique has been used in several vehicle design programs such as a Mars transfer habitat, pressurized lunar rover, and the redesigned international Space Station. Results of analysis performed for the Space Station astronaut exposure assessment are provided to demonstrate the applicability and versatility of the system.

Based on a study of a Mobile Pressurized Laboratory (MPL) concept made during the European Mars Mission Architecture Study conducted for ESA, further design development of the laboratory and interior functional layout of the rover has been performed. This includes volume optimization, wheel system and geometry, interior layout and functional zoning, airlock placement and ergonomics, radiation protection, ergonomic detailing of habitation functions like sleep, kitchen, hygiene, ergonomics of work environment for driver, glove box, laboratory and storage systems and spatial flexibility and adaptability.

Space Radiation Exposure Mitigation: Study of Select Materials

2006-07-17
2006-01-2103
The development of “next generation” human-rated space vehicles, surface habitats and rovers, and spacesuits will require the integration of low-cost, lightweight materials that also include excellent mechanical, structural, and thermal properties.

2009-01-2569
There is some urgency in creating this concept because NASA has begun building and testing development hardware for the lunar surface, including rovers, habitats and cargo off-loading equipment. Just as with microgravity operations, a lunar EVA work envelope is needed to guide designers in the formative stages of the program with the objective of avoiding difficult and costly rework.

Entry type is also affected by the vehicle and habitat interfaces such as air locks, hatches, and manned rovers. One concept for planetary exploration is to have an unpressurized vestibule attached to the habitat and have the spacesuit attached to the habitat wall acting as an air lock.
