The Digital Astronaut was described as "an integrated, modular modeling and database system that will support space biomedical research and operations, enabling the identification and meaningful interpretation of the medical and physiological research required for human space exploration, and determining the effectiveness of specific individual ...
The environment of space is lethal without appropriate protection: the greatest threat in the vacuum of space derives from the lack of oxygen and pressure, although temperature and radiation also pose risks. The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.
Aerospace physiology is the study of the effects of high altitudes on the body, such as different pressures and levels of oxygen. At different altitudes the body may react in different ways, provoking more cardiac output , and producing more erythrocytes .

Drosophila melanogaster, the common fruit fly, has been used to study the effects of spaceflight on living organisms.. On a July 9, 1946, suborbital V-2 rocket flight, fruit flies became the first living and sentient [citation needed] [] organisms to go to space, and on February 20, 1947, fruit flies safely returned from a suborbital space flight, which paved the way for human exploration.

Reverse phi illusion is the kind of phi phenomenon that fades or dissolves from its positive direction to the displaced negative, so that the apparent motion human perceive is opposite to the actual physical displacement. Reverse phi illusion is often followed by black and white patterns.
Psychological and sociological effects of space flight are important to understanding how to successfully achieve the goals of long-duration expeditionary missions. Although robotic spacecraft have landed on Mars , plans have also been discussed for a human expedition , perhaps in the 2030s, [ 1 ] for a return mission.
