Abstract
When Major Peake entered the ISS, he did so as a member of the Expedition 46 crew (see Appendix IV), which ran between December 11, 2015 and March 1, 2016, and then transitioned to Expedition 47 (see Appendix IV), which started on March 1 and finished on June 5, 2016. The account of Peake’s Expeditions is covered in this chapter and the next, but it is impossible to tell his story in isolation, so what follows is a snapshot of the crewmembers he shared his mission with. Also, since many readers may not be familiar with the complexity of operations on board the International Space Station (ISS), there are some brief descriptions of some of the routines that comprise day-to-day life on the orbiting outpost. But first, let’s introduce Peake’s crewmates.

Notes
- 1.
The astronauts breathe the same nitrox mix as the divers, but the pressure inside the EVA suits (4.3 psi) must be carefully regulated in response to the changing pressure as astronauts move up and down the water column. This is more difficult than it sounds, because the water exerts 0.5 psi per foot of depth so there might be a pressure differential of 2 psi if an astronaut is vertical. To compensate, the flow rate of gases to the suit is varied as the pressure changes.

An EVA Termination is different than an EVA Abort. An EVA Termination permits the crew to make safe the worksites and return to the airlock to complete a normal repressurization, whereas an EVA Abort requires an immediate return to the airlock to complete an emergency repressurization.
