Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVE:
Placing a human into free space, outside the protective confines of the space vehicle, has become an important component of space travel and exploration. An Extravehicular Activity (EVA) is a protocol that requires the astronaut to leave the aircraft to perform various duties such as repairs, observations, and experiments. One of the most important aspects of preparing for an EVA is to determine the physical requirements of the participants. Although the astronaut corps consists of individuals with specific skills, not everyone may be suitable for EVA activity. It is important, therefore, to determine whether the astronauts who perform EVAs differ from the general astronaut population in particular physiological variables.
