NASA's Swift telescope will plunge toward Earth after rescue mission called off

The mission to save NASA's sinking Swift Observatory was called off Wednesday, dooming the telescope to a fiery reentry later this year.NASA and Katalyst Space Technologies announced the news more than a month after the startup's Link spacecraft rocketed away to the telescope's rescue. Katalyst said Link will not attempt to capture Swift and boost it to a higher orbit because of problems with controlling the spacecraft. NASA said this means the telescope will plunge through the atmosphere after more than 20 years of tracking some of the biggest explosions in the universe, like gamma-ray bursts and exploding stars. NASA paid $30 million to Katalyst in an attempt to raise the telescope to a safer, longer-lasting orbit. Intense solar activity caused it to lose altitude faster than expected. The rescue spacecraft went into an uncontrollable spin a few weeks after its liftoff in early July.
