NASA’s DART rocket will collide with a space rock this evening in notable planetary protection test
"Hitting an asteroid is a tough thing to do."
NASA’s Twofold Space rock Redirection Test (DART) shuttle is tearing toward the space rock Didymos and its moonlet Dimorphos, and it’ll arrive at its objective this evening (Sept. 26). At 7:14 p.m. EDT (2314 GMT), in the event that all works out in a good way, DART will collide with Dimorphos trying to modify the moonlet’s direction. The mission is intended to test the hypothesis that this procedure could be utilized to redirect a space rock going directly toward Earth.
While neither Dimorphos nor Didymos represent a danger to our planet, and nothing that happens today can change that, the consequences of the DART mission will give critical information to researchers and specialists to foster designs for planetary guard. DART, which is overseen for NASA by Johns Hopkins College Applied Physical science Research center (JHUAPL), marks the very first planetary safeguard test. You can watch the DART space rock influence live on the web, politeness of NASA, starting at 6 p.m. EDT (2200 GMT).
“This is a thrilling time, for the organization as well as in space history and throughout the entire existence of mankind, in all honesty,” Lindley Johnson, NASA’s planetary safeguard official, said in a news gathering hung on Thursday (Sept. 22). “This showing is critical to our future here on The planet.”

As DART approaches Dimorphos, it will use its sole instrument, the Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO), to autonomously navigate to its impact zone. Considering that scientists estimate Dimorphos has a diameter of just 560 feet (170 meters), that’s no easy task.
“Dimorphos is a tiny asteroid,” Tom Statler, the mission’s program scientist at NASA, said during the news conference. “We’ve never seen it up close, we don’t know what it looks like, we don’t know what the shape is. And that’s just one of the things that leads to the technical challenges of DART. Hitting an asteroid is a tough thing to do.”
For context, Elena Adams, DART mission systems engineer at JHUAPL, said that DRACO won’t even spot Dimorphos until about an hour before impact, at which point it’ll be just one pixel in DRACO’s field of view. “At three minutes prior to impact, two minutes prior to impact, it is 42 pixels in size,” Adams said during the news conference.
NASA anticipates that DRACO should radiate practical one picture each second as it approaches Dimorphos at a speed of 4.1 miles each second (6.6 km/s), or 14,760 mph (23,760 kph). The office will communicate those pictures to general society progressively on a devoted stream. NASA will at the same time communicate extra live inclusion of the occasion starting at 6 p.m. EDT (2200 GMT). You can tune into one or the other transmission here on Space.com, as well as on NASA television, NASA’s site, and NASA’s virtual entertainment stations. NASA will likewise hold a news meeting after the effect, at 8 p.m. EDT (0000 GMT).
“The designing group will celebrate, and the cosmologists, at that point, will say, ‘alright, time to get to work,'” Statler said.
