What’s happened: NASA is celebrating the success of humanity’s first test of a planetary defense system: crashing a spacecraft into an asteroid in order to change its orbit. NASA’s Double Asteroid Redirection Test spacecraft, or DART, was intentionally smashed into the asteroid Dimorphos at 7.14pm ET last night, spelling the end to a successful 10 month mission.
A small camera mounted on DART livestreamed the spacecraft’s steady progress towards the 160 meter-wide asteroid, located about 6.8 million miles from Earth, back to controllers based at the Johns Hopkins University Applied Physics Laboratory. The strike was “basically a bullseye,” mission systems engineer Elena Adams said.
Why it matters: While Dimorphos had not been on course to crash into Earth, the project demonstrates NASA’s ability to deflect a dangerous meteorite collision in the future. Read the full story.
