NASA is mostly closed for business, including posting any new photos for the public, so we're glad we bookmarked this photo bookmarked this photo posted by the center at Goddard a couple weeks ago. This rabbit-suited-up engineer is preparing thermal blankets for the James Webb Space Telescope to be tested in a vacuum chamber. As described on the Instagram post: Those blankets are made of aluminized kapton, a polymer film that remains stable over a wide range of temperatures. Just as blankets insulate people from cold, these golden-colored thermal blankets help prevent heat from seeping into the vacuum chamber that will drop temperatures to mimic those of deep space.
