Spacewalk in progress. Watch astronauts @astro_josh (suit with red stripes) and Frank Rubio (unmarked suit) install new @Space_Station rollout solar arrays. The spacewalk is expected to last seven hours. x.com/i/broadcasts/1…
@NASA @astro_josh @Space_Station Is it cold up there ?
@JamesSweasyLive @NASA @astro_josh @Space_Station It can be both hot and cold depending on whether they're in the light or dark phase. There's a new "sunrise" every 90 minutes so their suits work to keep them comfortable.
@JamesSweasyLive @NASA @astro_josh @Space_Station Dog-Friendly gave a good answer. AFAIK, the delta (difference) in temperature between being in the sun and being in shade could be as much as 500 degrees F. When you're in the sun it's about plus 100 to 250, as soon as that equipment goes into the shade, it's minus 250 degrees.
