NASA launches spacecraft from Vandenberg Space Force Base to test asteroid defense concept – By AP (Military Times) / Nov 24 2021
LOS ANGELES (AP) — NASA launched a spacecraft Tuesday night on a mission to smash into an asteroid and test whether it would be possible to knock a speeding space rock off course if one were to threaten Earth.
The DART spacecraft, short for Double Asteroid Redirection Test, lifted off from Vandenberg Space Force Base atop a SpaceX Falcon 9 rocket in a $330 million project with echoes of the Bruce Willis movie “Armageddon.”
If all goes well, in September 2022 it will slam head-on into Dimorphos, an asteroid 525 feet across, at 15,000 mph.
“This isn’t going to destroy the asteroid. It’s just going to give it a small nudge,” said mission official Nancy Chabot of Johns Hopkins Applied Physics Laboratory, which is managing the project.
