SIRTF Launch Delayed

April 21, 2003 | NASA's next Great Observatory, the Space Infrared Telescope Facility (SIRTF), will not reach orbit before mid-August. Until April 18th it had been scheduled for launch by the end of the month.

The problem is not with the spacecraft itself, but with the Delta II rocket that will propel it into space. One of the booster's auxiliary solid-fuel rockets needs to be replaced because its engine nozzle is deteriorating.

"There simply is not enough time to remove and replace the rocket motor to support a SIRTF launch in advance of the Mars Exploration Rover[s]," said Karen Poniatowski (NASA Headquarters). The twin Mars rovers are also on Delta II rockets, and they have to be launched in June while the red planet is relatively nearby. SIRTF, in contrast, can go anytime.

For more information on the launch delay, see NASA's press release.
