Problems With WIRE Spacecraft End Mission
News story originally written on March 8, 1999

The Wide-Field Infrared Explorer (WIRE) will not be able to complete its scientific mission due to an on-board problem.

Soon after launch, hydrogen began venting from the spacecraft, which caused it to start spinning. Even though controllers are well on the way to gaining control of the craft, the hydrogen supply has been deleted. The hydrogen was needed to cool the on-board instruments.

"We are very disappointed at the loss of WIRE's science program," said Dr. Ed Weiler, NASA's Associate Administrator for Space Science. "We are establishing a formal anomaly investigation board to find out what happened. "

WIRE's mission was to study newly forming galaxies. By studying stars in different stages of formation, scientists hoped to better understand how our own sun formed.
