The DART spacecraft cost hundreds of millions of dollars, all so it could crash into an asteroid, but for a good cause, of course. The team on the International Space Station demonstrated how kinetic impacts affect bodies in space by tossing boxes at a floating astronaut standing in for the asteroid. But you have to field test it at least once to see if your simulation is accurate.
In case you’re wondering why computer simulations aren’t taking care of this kind of planetary defense, fear not-they are. NASA, ESA, CSA, Cristina Thomas (Northern Arizona University), Ian Wong (NASA-GSFC) Joseph DePasquale (STScI) More About the DART Mission NASA, ESA, Jian-Yang Li (PSI) animation: Alyssa Pagan (STScI)īoth the Hubble Space Telescope (above) and James Webb Space Telescope (below) were pointed at Dimorphos when the DART came for the asteroid and captured the impact. Scientists will monitor the asteroid’s orbit to see if it changes after the DART spacecraft crashed into it. ASI/NASAĭART launched back in November using a SpaceX Falcon 9 rocket and impacted the asteroid Dimorphos at 14,000 miles per hour. The probe will continue to take photos of the post-collision crater and asteroids in the coming few days. The first images from its two optical cameras, LUKE and LEIA, show a cloud of ejecta around Dimorphos, with Didymos in the foreground (below). ATLAS Project SeptemNew Images of DART Collision with an AsteroidĭART deployed a probe about a week in advance of the asteroid collision, and it was following along to capture photos. The technical term for this spacecraft collision with an asteroid is a “kinetic impact.” The people who approved funding for this mission have either seen too many disaster movies or, you know, heard what happened to the dinosaurs. But NASA decided to bonk into Dimorphos anyway to see what happens. They are just out there minding their own business. In comparison, DART was only 62 feet with its solar panels unfurled. The asteroids are not headed for Earth.
The DART Spacecraft Crashes Into an Asteroidĭimorphos is only 530 feet long and orbits another asteroid called Didymos, which is 2,560 feet long, or about half a mile. Other images came in from NASA’s other projects, including telescopes on Earth and in space. It took some great detailed images as it hurtled into Dimorphos and then stopped transmitting. The camera onboard the DART spacecraft tracked the asteroid from a tiny speck into a specific target. The agency crashed a spacecraft into an asteroid seven million miles from Earth, to test whether it’s a viable option to knock one off course.
