NASA is racing to save its Swift telescope from falling back to Earth with a daring rescue mission. The salvage effort gets underway as soon as this week with the planned launch of a robotic lifesaver. NASA has hired Katalyst Space Technologies to boost Swift to a higher orbit where it can continue hunting for some of the universe’s biggest explosions. Launched in 2004, Swift has been sinking faster and faster because of recent intense solar activity. It needs to get to a higher orbit as soon as possible to survive. Otherwise, it will come crashing down.
