China's stranded astronauts returning from space station on spacecraft that brought new crew

Three astronauts stranded on the Chinese space station return home aboard the ship that brought their replacements. The trio had been on the station for six months and were scheduled to return on November 5, four days after the new crew arrived. Their return was aborted because their Shenzhou-20 spacecraft had minor cracks in a window, apparently caused by space debris. The Chinese space agency announced that it would return on Friday aboard the Shenzhou-21 spacecraft. The astronauts traveled to the Tiangong space station in April.
