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 sunshield component attaches to the main spacecraft, and its booms expand outward spreading out the heat shield and separating the layers. [24] During launch the shield is folded up; later, when it is in space, it is carefully unfurled. [24] When the sunshield is fully spread open, it is 14.6 meters (48 ft) wide by 21.1 meters (69 ft) long ...

A space sunshade or sunshield is a parasol that diverts or otherwise reduces some of the Sun's radiation, preventing it from hitting a spacecraft or planet and thereby reducing its insolation, which results in reduced heating. Light can be diverted by different methods.
