`U' researcher to test `kite and string'

Even scientists have bad luck sometimes. But good ones try again.

Four years ago, Engineering Prof. Brian Gilchrist collaborated with NASA on an experiment modeled after Ben Franklin's legendary discovery.

A satellite and copper-and-nylon cable replaced the infamous kite and string. The attempt to link the shuttle with the satellite was unsuccessful due to a last-minute bolt which caused the cable's reel mechanism to jam after takeoff.

This afternoon the Tethered Satellite System will get another chance.

"We're as ready as we'll ever be," Gilchrist said.

The space shuttle Columbia will begin a 13-day mission at 3:18 p.m. from Kennedy Space Center in Cape Canaveral, Fla. A main goal of the mission will be to test the effectiveness of the 13-mile-long cable linking the shuttle to the satellite.

The mission could have a lasting impact on simultaneous measurements used in future space journeys and the development of space stations.

The scientists hope to discover more information on the electrodynamics of the ionosphere, the part of the earth's atmosphere where electrically charged gases and magnetic fields are produced.

Charged electrons will travel in the cable from the satellite to the shuttle, where they will be released back into the ionosphere.

"We are very proud of them," said Engineering Prof. Tamas Gombosi. "This is really great for the University."

Although the shuttle blasts off today, the satellite itself will not be deployed until Saturday afternoon.

Gilchrist stressed last night that the team of scientists were much more prepared this time around.

"They've had to assess the problems of the past," said Engineering Prof. Thomas Donahue. "I feel confident it will succeed this time."

The mission is a joint collaboration between Italian and American scientists.
