Recent space shots have shown that when astronauts embark on long duration space flights they are going to need artificial gravity to combat weightlessness.
Recent space shots have shown that when astronauts embark on long duration space flights they are going to need artificial gravity to combat weightlessness. This will probably be induced by spinning the spacecraft - and to test human reaction to these conditions a special spinning machine has been developed by a space research organisation in California.
The first experiment has just been completed. Four young men spent seven days without a break aboard the simulator. It took them about a day to get used to the spinning motion.
Then, while engineers and medical men monitored their activity in a control room, they set to work on a test programme, venturing out onto the long arm which attached the spinning cabin to a central pivot.
Outside the cabin, the volunteers used slings to neutralise the effect of gravity, thus duplicating space conditions as much as possible and enabling them to climb the walls of the rotating machine.
Finally, after more than 39,000 revolutions, the men emerged from their spinning machine -- clutching onto rails and showing symptoms of giddiness, but otherwise none the worse for their experience.
