Nudge that rock, nudge that rock Thirty-three minutes off the clock!
007skaty Blasted rock and dust shortened Dimorphos's orbit around Didymos by 33 minutes instead of the predicted 73 seconds.
007skaty The DART spacecraft smashes into the asteroid Dimorphos, creating a massive debris cloud.
007skaty Bop incoming asteroids to discover how gravitational nudges steer hazards away from Earth.
Asteroid tail: The DART impact created a massive debris tail over 10,000 kilometers long, briefly making Dimorphos look like a comet.
A spacecraft designed to alter the trajectory of a celestial body by intentionally colliding with it. In September 2022, NASA's DART spacecraft struck the asteroid Dimorphos to test this planetary defense method.
Which space agency built the LICIACube nanosatellite that photographed the DART impact?
Which asteroid was the smaller target moonlet impacted by NASA's DART spacecraft in 2022?
What physical phenomenon caused the DART deflection to be much stronger than expected?
How far was the Didymos system from Earth when the DART collision occurred in 2022?
