The latest spacewalk took five hours and 20 minutes, but the astronauts experienced seven cycles of day and night during that time alone because the space station is orbiting the earth at 17,500 MPH, so lots of quick, bright sunlight and quick, cold darkness, NASA says the astronauts outside the space station don't feel the extreme cold and heat, but they do have heated gloves to keep their hands from getting too cold to more.
最近一次的太空行走用了5小時20分鐘,但太空人在這段時間內就經歷了7個晝夜循環,因為空間站以17500英里/小時的速度繞著地球運行,所以大量快速明亮的陽光和快速寒冷的黑暗,NASA表示,空間站外的太空人並沒有感覺到極度的寒冷和炎熱,但他們有加熱手套,以防止他們的手太冷到更。
