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 ...
In November 2017, the Space Telescope Science Institute announced the selection of 13 Director's Discretionary Early Release Science (DD-ERS) programs, chosen through a competitive proposal process. [ 232 ] [ 233 ] The observations for these programs – Early Release Observations (ERO) [ 234 ] [ 235 ] – were to be obtained during the first ...
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.
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).

This heat shield was composed of phenolic formaldehyde resin. During reentry, this material charred and melted away, absorbing and carrying away the intense heat in the process. The heat shield has several outer coverings: a pore seal, a moisture barrier (a white reflective coating), and a silver Mylar thermal coating that looks like aluminum foil.
Former President Trump said he would create a national guard for the Space Force and build an “Iron Dome” in the U.S. as he laid out his military plans during a Monday address. Trump, speaking ...
