[2] Other significant effects include a slowing of cardiovascular system functions, decreased ...
Effects of ionizing radiation in spaceflight.

The torso is equivalent in height and weight to ...
Research on the medical emergencies that may occur in space include fatal and nonfatal arrhythmia, heart attacks, cardiac arrests, embolisms, massive hemorrhages, renal stone formations, fatal and non-fatal infections, and thrombotic complications. Of these conditions, only arrhythmia, renal colics, and infections have occurred in the history ...

Cabana, holding Shepherd's eye open, prepares to measure Shepherd's intraocular pressure using a tonometer (in his right hand). Spaceflight associated neuro-ocular syndrome (SANS), [1] previously called spaceflight-induced visual impairment ...
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.
