NASA has no plans to launch missions to test those methods, however. Gravity tractors and ion beam deflection are others. At today’s briefing, Johnson said changing an asteroid’s trajectory through imparting kinetic energy is just one method. Lindley Johnson is NASA’s Planetary Defense Officer and heads the Planetary Defense Coordination Office (PDCO) at NASA Headquarters. Protecting Earth from asteroids and comets - Near Earth Objects (NEOs) - that might cause regional or global catastrophes is called planetary defense. The European Space Agency is launching the HERA mission in 2024 that will visit the double asteroid pair and perform a post-impact survey in 2026. That will not be the last chance to see what happened, however. “I don’t want to get into the middle of that debate, but I would be surprised if we had a firm measurement of the period change in less than a few days and I would be really surprised if it took more than three weeks.” Statler said there’s a “friendly rivalry” between the optical observers and radar observers on the science team as to who will detect it first. The measurements to detect the change in Dimorphos’s orbit will come from ground-based telescopes and radars over a period of time. They will not see the impact itself, but might detect the brightness of ejecta spewed out into space. NASA’s Hubble Space Telescope in Earth orbit, James Webb Space Telescope at the Sun-Earth Lagrange Point-2 (SEL-2), and the Lucy spacecraft on its way to the Trojan asteroids will take a look, too. It will separate from DART before impact and collect images of those last moments, though it will take some time to get them back due to slow data rates. It’s kind of astonishing that we are actually doing that and what that bodes for the future.”Ī tiny Italian cubesat, LICIAcube, is along for the ride. This is stuff of science fiction books and really corny episodes of Star Trek when I was a kid. We are changing the motion of a natural celestial body in space. He also commented on the significance of the mission more broadly. Tom Statler, DART Program Scientist at NASA, told reporters today that “we’re doing this test when we don’t need to, on an asteroid that isn’t a danger, just in case we ever do need to if we discover an asteroid that is a danger.” Tom Statler, DART Program Scientist, NASA. When the screen goes blank and there’s a loss of signal, cheers will ring out rather than alarm because it means the impact was successful.

NASA TV will provide live coverage Monday evening as DART zeroes in on Dimorphos.

The plan is for DART to ram itself into Dimorphos while scientists on Earth measure whether its orbit around Didymos changes. This asteroid poses no threat to Earth, but NASA wants to find out if this kinetic energy method would work if the day comes when it’s needed.ĭART was launched from Vandenberg Space Force Base, CA on NovemPST (November 24 EST) headed to the asteroid Didymos and its tiny moon Dimorphos 7 million miles away.

The Double Asteroid Redirection Test is just that, a test to see if it is possible to divert an asteroid’s trajectory. The data from the crash can help scientists create mini-impacts in a lab and build sophisticated computer models based on those results.On Monday, a NASA spacecraft will deliberately crash itself into an asteroid to change its orbit just a bit. DART will be the first-ever space mission to demonstrate asteroid deflection by a kinetic impactor. The Double Asteroid Redirection Test or Dart mission, is the demonstration of kinetic impactor technology, hitting an asteroid to adjust its speed and path. In September, we’ll refine where DART is aiming by getting a more precise determination of Didymos’ location,” Julie Bellerose, the DART navigation lead, said in a statement. “Seeing the DRACO images of Didymos for the first time, we can iron out the best settings for DRACO and fine-tune the software. The images are significant since the spacecraft will depend on this ability to see and process images of Didymos and Dimorphos, once it too can be seen, to guide the spacecraft toward the asteroid, especially in the final four hours before impact.
