In August this year ESA, CNES and NASDA started the first period of a
study to validate countermeasures to cope with the demands of
long-duration missions aboard the International Space Station when 14 male
volunteers were confined to bed for 90 days, lying in a strict -6°
head-down tilt position, the best for simulating certain effects of the
weightless environment of space.

Long stays in weightlessness affect the human body, as evidenced by
changes to bone and muscle in particular. During the “bedrest” study
conducted at the MEDES space clinic in Toulouse (France), scientists have
been able to collect a wealth of data and will continue to do so with a
second group of subjects currently being selected, while the first group
resume their ordinary lives before Christmas. The participants will be
followed up in specific check-ups on bone and muscle status at set
intervals over one year.

The scientists and volunteers will be sharing their experience with media
representatives at a press conference to be held on Monday 17 December
from 11:00 to 12:30 at Toulouse Rangueil hospital, Avenue Joean Poulhës,
Salle Claude Louis (tbc by CNES).


Interested candidates for the second campaign, planned from March to
August 2002 can still apply. Relevant information can be obtained either
