EXPERIMENT INFORMATION

Cardiovascular Evaluations (ASTP006)
Research Area:
Cardiovascular physiology
Species Studied
Scientific Name: Homo sapiens Species: Human

Description
OBJECTIVES:
The objective of this investigation was to determine the response of the cardiovascular system to weightlessness. However, during reentry, the crew was exposed to toxic gases (mostly nitrogen tetroxide). Because of this episode during the Apollo-Soyuz Test Project (ASTP), most planned postflight evaluations were curtailed, altered or deleted.
