Scientists Examine Artificial Gravity

There is no doubt that future Red Planet explorers will be more than a little weak-in-the-knees after a round-trip jaunt lasting some three years. Research shows that exposure to microgravity weakens muscle, causes bone loss and plays havoc with a person’s balance and coordination. But a team of scientists and engineers here at the Massachusetts Institute of Technology’s (MIT) Man-Vehicle Laboratory are tackling the problem with experiments in artificial gravity.
