WASHINGTON: Nasa launched a robotic mission on Friday to try to prevent one of its aging telescopes from burning up in the atmosphere, a complicated operation expected to last several months.

The unprecedented $30 million effort involves sending a robot to rescue the Swift space telescope that’s currently falling towards Earth.

If successful, the mission could pave the way for giving other satellites a second life.

Initially scheduled for June 30, the robot’s launch was postponed due to weather and then technical issues. It finally took place on Friday from an atoll in the Pacific Ocean.
