00:21 [Voix-off] After body electrodes have been attached to monitor heartbeat and breathing, the first items of clothing are the water-cooled underwear and a urine collector.
00:32 A spacesuit is basically a sealed bag of atmosphere, a stiffened balloon, pumped up to counteract the vacuum of space.
00:40 It might be called a one-man spaceship of the smallest possible dimensions.
00:44 The pressure suit has to guard against extreme temperatures, hard radiation from the sun, and tiny meteorites.

04:44 [Voix-off] They carried with them the biological day of the Earthling. Three meals, a snack or two, eight hours of sleep.
04:54 Time to work, time to relax, time to reflect.
05:03 Three days falling upward to the moon.
05:12 Look down, look down.
05:18 That fragile bubble of life afloat on a sea of nothing.
05:26 Spaceship Earth.
