in NASA's hypergravity study will be fitted with an EKG, a
blood-flow monitor and a biosensor vest before entering the 20 G
Centrifuge at the NASA Ames Research Center in Mountain View,
Calif. To experience the effects of 2 G -- twice Earth's
gravitational force -- test subjects (men ages 18 to 35) will be
spun at nearly 15 revolutions per minute.
