In brief

NASA launched a robot on Tuesday to save the Swift space telescope, which scientists launched in 2004. The telescope is falling toward Earth because solar cycles expand the atmosphere and create drag. The rescue robot, built by the startup Katalyst, will latch onto Swift with three arms. It will tow the telescope 300 kilometers higher. This mission has a 50-50 chance of success, but it could help us repair other satellites in the future.

On Tuesday, NASA launched a robot in order to rescue the aging Swift space telescope from burning. NASA launched the Neil Gehrels Swift Observatory telescope in 2004, and scientists have used it since then. Although they originally designed it for a two-year mission, the device is still operating. The telescope is very important because it detects gamma-ray bursts, which are the most energetic explosions in space. Swift is currently in low Earth orbit at an altitude of approximately 600 kilometers. However, the telescope does not have its own motor, and it has started to lose altitude. Sun cycles expand the atmosphere of the Earth, which creates drag on the telescope. As a result, the spacecraft is falling and it might burn up without a rescue. To prevent this, the U.S. startup company Katalyst has built a robot called LINK. On Tuesday at 1023 GMT, a jet released a small Pegasus rocket, which carried the robot into space. After the robot arrives near the telescope, it must search for the device in space. The robot will use three movable arms to latch onto the back of the telescope. It will then tow Swift 300 kilometers higher, which will keep it in a safe orbit. The towing process will take at least a month, and the mission may last into the autumn. This rescue mission will cost 30 million dollars, whereas the original telescope cost 250 million dollars. NASA astrophysicist Regina Caputo said that the team has a 50-50 chance of success. However, the team has decided to try this because they want to save this special telescope. If this mission succeeds, it will show how we can repair, upgrade, and refuel other satellites in space.
