NASA's "Armageddon" mission a success

Prior to impact, it took Dimorphos 11 hours and 55 minutes to orbit its larger parent asteroid Didymos. Astronomers used ground-based telescopes to measure how Dimorphos’ orbit changed after impact.

Now, it takes Dimorphos 11 hours and 23 minutes to circle Didymos. The DART spacecraft changed its orbit by 32 minutes.

Initially, astronomers expected DART to be a success if it shortened the trajectory by 10 minutes.
