Shuttle Crew to Face In-Depth Aging Tests

From Times Wire Reports

The seven astronauts who will take off from the Kennedy Space Center aboard space shuttle Columbia today for two weeks of medical tests will be young in years but old at heart--at least in orbit. “In two weeks of spaceflight, we can induce changes in blood pressure regulation that might approximate 30 or 40 years of aging and then we can return back to a normal state. It’s just a phenomenal research model,” said Jim Pawelczyk, a physiologist.
