After the successful impact of NASA’s DART mission on the Dimorphos asteroid, scientists have encountered a series of unexpected outcomes, the latest being the unanticipated lengthening of the asteroid’s orbital period around its larger partner, Didymos.
In September 2022, NASA deliberately crashed its DART spacecraft into a small asteroid some 6.8 million miles from Earth, in an attempt to redirect its trajectory as a test-run for any future rock that might threaten Earth.
