Integrated Thermal Control and Qualification of the Mars Rover

1996-07-01

The Mars Rover has a lightweight integrated structure/insulation that has been environmentally tested and qualified for the 1996 launch for the Pathfinder mission to Mars. ...The basic structure with insulation, called the Warm Electronics Box (WEB), accounts for only 10% of the total Rover mass. The WEB is a thermal isolating composite structure with co-cured thermal control surfaces and an ultralightweight hydrophobic solid silica aerogel which minimizes conduction and radiation. ...This design provides excellent thermal insulation at low gas pressures and meets the structural requirements for spacecraft launch loads and for a 60 g impact landing at Mars without damage to the insulation or structure. The Rover design has been thermally qualified in a series of both static and transient thermal-vacuum testing in vacuum and 8 torr wind environments simulating all predicted environmental conditions.

Thermal Design Considerations for a Mars Rover

The ground experiments are carried on a wheeled Mars Rover vehicle, which comprises a service module and the 40kg Pasteur payload module containing the sample analysis packages and sample collection and transport systems. ...The ExoMars mission is due to be launched in 2009. The Rover will be built to operate autonomously and travel several kilometres over the Martian surface, carrying out in-situ soil sample analyses, and identifying and characterising possible hazards to future human exploration. ...Where possible, the Rover thermal control will be based on existing space-qualified technology used in novel configurations to protect the Rover and its payload from the harsh environment of the Martian surface.

An integrated lightweight structure and thermal insulation has been developed for the Mars Rover Warm Electronics Box (WEB). It combines a low thermal conductivity fiber reinforced composite structure with co-cured thermal control surfaces and an ultralightweight hydrophobic solid silica aerogel which eliminates convection and minimizes conduction and radiation.

The rescue system was utilized effectively to extract an injured astronaut up a slope of15-25° and into a surface mobility rover for transport to a simulated habitat for advanced medical care. Further research is recommended to evaluate the effects of reduced gravity and to develop synergies with other surface systems for carrying out the contingency procedures.

This paper discusses recent advances in the binary-coded IOSPEC technology towards providing an integrated chemical analysis system for manned space systems and planetary rovers. An active shutter array is being developed based on a thin-film structure that enables broad-band optical switching and multiplexing at ms speeds with no moving parts for reliable long-term operation.
