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.
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 ...
layering materials of emergency blanket 32 layers are 0.45mm thick. First developed by NASA ' s Marshall Space Flight Center in 1964 for the US space program, [2] [3] [4] the material comprises a thin sheet of plastic (often PET film) that is coated with a metallic, reflecting agent, making it metallized polyethylene terephthalate (MPET) that is usually gold or silver in color, which reflects ...
The coating was absent from a small margin of the sides adjacent to the uncoated (bottom) side. To waterproof the tile, dimethylethoxysilane was injected into the tiles by syringe. Densifying the tile with tetraethyl orthosilicate (TEOS) also helped to protect the silica and added additional waterproofing. Diagram of a HRSI tile.
The material was used again on NASA's 2011 Mars Science Laboratory in the bridle cables. [ 5 ] Vectran is a key component of a line of inflatable spacecraft developed by Bigelow Aerospace , [ 6 ] not only on two stations which are in orbit [ 7 ] [ 8 ] but also the Bigelow Expandable Activity Module which NASA is testing for its radiation ...
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.

Personal shielding against more energetic radiation such as gamma radiation is very difficult to achieve as the large mass of shielding material required to properly protect the entire body would make functional movement nearly impossible. For this, partial body shielding of radio-sensitive internal organs is the most viable protection strategy.
