Event Summary

United States===NASA's Double Asteroid Redirection Test (DART) successfully altered the orbit of the asteroid Dimorphos around its larger companion Didymos, and consequently, their combined orbit around the Sun. This marks the first time humanity has deliberately changed a celestial body's solar orbit. The DART spacecraft impacted Dimorphos in 2022, and recent findings, led by Rahil Makadia, confirm a slight but significant change of 0.15 seconds in their 769-day solar orbit. Steven Chesley of United States===NASA noted this as an important data point for future asteroid deflection missions. The European Space Agency's Hera spacecraft is scheduled to arrive in November to further investigate the impact's aftermath.
