And that's kind of astonishing that we are actually doing that, and what that bodes for the future of what we can do.'

'This is stuff of science fiction books and really corny episodes of Star Trek from when I was a kid, and now it's real. Humanity has never done that before,' says Tom Statler, NASA's DART program scientist. We are changing the motion of a natural celestial body in space. Still, the folks working on the DART mission seem to understand that their project can sound kind of far out. When that happens, says Lu, 'we should have, in advance, some experience knowing that this would work.' Lots of asteroids have yet to be found and tracked 'Someday, we are going to find an asteroid which has a high probability of hitting the Earth, and we are going to want to deflect it.' 'The bottom line is, it's a great thing,' says Ed Lu, who serves as executive director of the Asteroid Institute, a program run by a nonprofit dedicated to planetary defense. What's more, in a couple of years, the European Space Agency will send a mission called Hera out to this double asteroid system, letting scientists gather even more information on the impact's effects.Īll of this should reveal just how an asteroid reacts to a deliberate push, and scientists can take that information to help them make contingency plans to get ready for future threats. Telescopes on all 7 continents, as well as space telescopes like James Webb, will also view the collision and its aftermath for weeks, making observations that will let astronomers precisely measure how the asteroid's path got altered. Cheers erupted in the control room as the screen went red from loss of signal.Ī smaller spacecraft nearby was watching, and will send images back to Earth over the following days. In the final minutes before impact at 14,000 miles per hour, NASA lost the ability to send commands to the spacecraft as scientists simply watched and waited. The spacecraft's onboard navigation systems initially targeted the larger and easier-to-spot asteroid, only switching their attention to Dimorphos in the last hour of the mission. Images from the DART spacecraft's camera were the first chance that scientists had to see the asteroid they had been working to hit. These two asteroids are so far away that telescopes see them as a single point of light that dims and brightens as Dimorphos goes around. The DART impact should change the path of Dimorphos so that it moves closer to the big asteroid and takes less time to go around, doing so perhaps once every 11 hours and 45 minutes.

Right now, a full circuit takes 11 hours and 55 minutes. Instead, the impact should slightly shorten the time it takes for Dimorphos to orbit its bigger asteroid pal. 'It's just not scientifically possible, just because of momentum conservation and other things.' 'There is no scenario in which one or the other body can become a threat to the Earth,' says Thomas Zurbuchen, associate administrator for the science mission directorate at NASA.

NASA officials stressed that there was no way their test could have turned either of these space rocks into a menace. It's about 525 feet across and orbits another, larger asteroid. She says the collision is just a nudge that's similar to 'running a golf cart into the Great Pyramid.'ĭimorphos is around 7 million miles away and poses no threat to Earth. This isn't going to blow up the asteroid,' Nancy Chabot, the DART coordination lead at the Johns Hopkins University Applied Physics Laboratory, said earlier. 'This really is about asteroid deflection, not disruption. It will be about two months, scientists said, before they will be able to determine if the impact was enough to drive the asteroid slightly off course. The impact was the culmination of NASA's Double Asteroid Redirection Test (DART), a 7-year and more than $300 million effort which launched a space vehicle in November of 2021 to perform humanity's first ever test of planetary defense technology. 'As far as we can tell our first planetary defense test was a success,' said Elena Adams, the mission systems engineer, who added that scientists looked on with 'both terror and joy' as the spacecraft neared its final destination. In images streamed as the impact neared, the egg-shaped asteroid, called Dimorphos, grew in size from a blip on screen to have its full rocky surface come quickly into focus before the signal went dead as the craft hit, right on target.Įvents transpired exactly as engineers had planned, they said, with nothing going wrong.
