NASA is about to conduct the first real-world test of Earth's planetary defence capabilities, by smashing a spacecraft into an asteroid in an attempt to change its orbit.
at Johns Hopkins University in Maryland and his team hope the asteroid system can act as a test-bed for dealing with potentially deadly space rocks.“This is an experiment at the kinds of scales that we want to use, or that we might use, if we ever need to deflect an asteroid for real,” said Rivkin during a press conference at the Europlanet Science Congress in Granada, Spain, on 19 September.
Although DART has a camera onboard, the spacecraft will be destroyed on impact, so won’t be able to see the outcome. Instead, the team will rely on LICIACube – a sister spacecraft from the Italian Space Agency that separated from DART on 11 September – to take detailed observations.
