The hostile environment of space limits the useful life of coatings. New coatings, which are expected to be much more stable in space and therefore have longer useful lives, will be tested. MISSE will also address a major problem for a crewed exploration of Mars: shielding the crew from the very energetic cosmic rays found in interplanetary ...
The golden areas are MLI blankets on the Mars Reconnaissance Orbiter. The principle behind MLI is radiation balance. To see why it works, start with a concrete example - imagine a square meter of a surface in outer space, held at a fixed temperature of 300 K (27 °C; 80 °F), with an emissivity of 1, facing away from the sun or other heat sources.
Astronautical hygiene evaluates, and mitigates, hazards and health risks to those working in low-gravity environments. [1] The discipline of astronautical hygiene includes such topics as the use and maintenance of life support systems, the risks of the extravehicular activity, the risks of exposure to chemicals or radiation, the characterization of hazards, human factor issues, and the ...

A cleaning event is a phenomenon whereby dust is removed from solar panels, in the context of exploration and science rovers on Mars, supposedly by the action of wind. The term is used on several NASA webpages; generally supposing that Martian winds have blown dust clear off the probes on Mars, including the solar panels which power them ...
A Viking lander being prepared for dry heat sterilization – this remains the "gold standard" [1] of present-day planetary protection.. Planetary protection is a guiding principle in the design of an interplanetary mission, aiming to prevent biological contamination of both the target celestial body and the Earth in the case of sample-return missions.

AVCOAT was used for the heat shield on NASA's Apollo command module. [4] In its final Apollo form, this material was called AVCOAT 5026–39. Although AVCOAT was not used for the Space Shuttle orbiters, NASA again used the material for its Orion spacecraft [5] first for the initial Orion test and then for a different type of heat shield for the later Orions.
