Week 2 Ageing and microgravity environments

Completion requirements

This is black and white image of a recording of heart rates measured for the crew of the Apollo 11 mission (Neil Armstrong, Buzz Aldrin and Mike Collins). At the launch, their heart rate printouts were similarly elevated as indicated by sharp peaks and troughs. At the lunar touchdown, only Armstrong's heart rate was shown and is highly elevated. During the EVA (extra vehicular activity), the heart rates of Armstrong and Aldrin were shown as elevated, but only Armstrong's heart rate was shown as elevated during the lunar lift-off stage. There were no traces of Collins' heart rate for the lunar touchdown, EVA and lunar lift-off stages.
