NEEMO 5 was
the longest and most challenging mission to date. The NEEMO 5 crew's
mission began with splashdown on June 16 and ended with decompression
and splash-up on Sunday, June 29, 2003.
The NEEMO 5
crew included three astronauts -- Clayton
Reisman and Peggy
Whitson -- and Emma

of the mission included experiencing living conditions similar to
those on the Space Station; developing new ways of interacting with
researchers from a remote laboratory location; developing a communications
system for use when a spacewalking crew is working at a significant
distance from the habitat; and exercising teambuilding, interpersonal
and leadership skills.
Living in microgravity
for days or months can cause a number of physiological, psychological
and behavioral changes, both during flight and after landing. To
gather additional data on some of these effects, the NEEMO 5 crew
participated in 12 research activities. These include a study of
how their environment affects sleep and the body’s immune system,
the growth of bacteria in the habitat, the use of wireless medical
monitoring equipment and nutrition-related studies.
They also tested
a piece of equipment that could be used by future spacewalkers.
The In-suit Doppler was used to look for nitrogen bubbles in the
blood stream, which could provide an early warning of possible decompression
