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 ...
Whipple shield used on NASA's Stardust probe. The Whipple shield or Whipple bumper, invented by Fred Whipple, [1] is a type of spaced armor shielding to protect crewed and uncrewed spacecraft from hypervelocity impact / collisions with micrometeoroids and orbital debris whose velocities generally range between 3 and 18 kilometres per second (1.9 and 11.2 mi/s).
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.
(M. Dowman, 1989) [1] 1990s era NASA design featuring 'spam can' type habitat landers. The downside may be minimal shielding for the crew, and two ideas are to use Mars materials, such as ice, to increase shielding, and another is to move underground, perhaps caves. A Mars habitat is a hypothetical place where humans could live on Mars.
NASA's human Mars exploration plans have evolved through the NASA Mars Design Reference Missions, a series of design studies for human exploration of Mars. In 2017, the focus of NASA shifted to a return to the Moon by 2024 with the Artemis program , a flight to Mars could follow after this project.

The first Mars Design Reference Mission [4] was a NASA study completed in May 1993, under the auspices of the Space Exploration Initiative (SEI). [5] The objective [ 6 ] was to develop a "Reference Mission" based on previous studies and data, where the Reference Mission serves as a basis for comparing different approaches and criteria from ...
