Welcome to NASA’s hot asteroid autumn
An unusual disc-shaped object from space landed last month on the barren sands of a U.S. military testing ground.Scorched from its fiery journey through the atmosphere, the capsule was lifted by helicopter and taken to a custom-built clean room at the Utah Test and Training Range, where it sat unopened under a continuous flow of nitrogen to avoid contamination by the germs of its new home planet.It was flown the next day to NASA’s Johnson Space Center in Houston.
