National Aeronautics and Space Administration (NASA) has ended the spacewalk involving UK astronaut Tim Peake after his US colleague reported water in his helmet. Tim Kopra reported a small amount of water, but the flight director took the precaution of ending the event early. The agency is under a ruling to terminate a spacewalk under such circumstances after an incident in 2013, when a European astronaut developed a significant helmet leak. The astronauts were outside the space station for four hours 43 minutes. The main objective of the spacewalk— replacing a failed electrical box— had already been completed. Just before 17:00 GMT, Colonel Kopra, a NASA astronaut who is a veteran of two spacewalks, told mission controllers a water globule measuring a few inches across had developed inside the helmet. He was able to sample the water and found it was cold, which is indicative of a leak from part of the US-built suit’s cooling system.
1. Why did Tim Peake end his spacewalk early?
2. What is the main task of this spacewalk?
