DART) space mission’s scientific results. Indeed, NEO-MAPPERS were among the scientists doing the cover of the international scientific journal Nature about the NASA’s Double Asteroid Redirection Test (a.k.a. The NASA DART first results have just did the cover of the journal Nature. In addition to the remote sensing suite of instruments, Hera will also deploy two Cubesats, Milani and Juventas, which will operate over a few months in vicinity of the asteroid providing unique scientific measurements. An Italian Cubesat called LiciaCube will be deployed by DART before the impact and will observe its happening as well as the first 100 seconds following it. AIDA will combine the data obtained by the NASA Double Asteroid Redirection Test (DART), which will impact the secondary of the binary asteroid Didymos, named Dimorphos, and observe the resulting change in the orbital period of the secondary from ground-based observatories, and by the ESA Hera mission, which will rendezvous with the target, characterise it in great details, including its internal properties and the crater made by DART and measure the momentum transfer efficiency.

'Assuming we don't have any major surprises, of course, we think that this technique would be then available, would be a part of the toolbox that we are starting to build of capabilities to deflect an asteroid,' says Johnson.Īfter this test, he says, NASA will want to try out other asteroid deflection techniques like the so called 'gravity tractor' approach, which involves stationing a spacecraft near an asteroid to apply a small tug of gravity.The main purpose of the Asteroid Impact and Deflection Assessment (AIDA) collaboration is to support the demonstration and validation of the technology needed to deflect a hazardous asteroid by means of a kinetic impactor as well as to improve our understanding of the impact process and the momentum transfer to the target asteroid. What's more, the European Space Agency is expected to launch a mission in 2024 that will travel to these two asteroids and be able to observe the crater on Dimorphos and determine the mass of this asteroid.Īll of these results should help NASA and other space agencies understand what could be possible to do with this kind of 'kinetic impact deflection' approach in the future if an asteroid is headed toward Earth. NASA consideres interstellar mission that could last 100 yearsĪ tiny satellite jettisoned from the spacecraft 10 days before the impact should send back images of the collision itself and the resulting blast of debris. 'It is four hours of watching paint dry, but kind of terrifying at the same time because the spacecraft is completely autonomous,' says Elena Adams, the mission systems engineer at the Johns Hopkins University Applied Physics Laboratory. In the last few hours of the mission, managers back on Earth will only be able to watch as the spacecraft flies itself and homes in on its target. 'So it's like a small golf cart running into a Great Pyramid,' says Chabot - only this 'golf cart' will be going 15,000 miles per hour. It's the small asteroid, Dimorphos, that will get smacked by the spacecraft. This asteroid is orbited by a smaller asteroid called Dimorphos, which is about 525 feet across. 'There is absolutely no way that the DART test is a threat to the Earth,' she says.Īfter the DART spacecraft launches, it will spend about 10 months traveling out toward an asteroid called Didymos, which is about 2,500 feet across. The asteroid targeted by DART isn't a danger to the planet now, and Chabot says there's no chance this mission could make it one. It is absolutely not asteroid disruption, which is how it goes a lot of times in the movies,' says Chabot, who serves as DART's coordination lead. 'DART is demonstrating asteroid deflection. But there are plenty of smaller asteroids, the size that could take out a city, that still haven't been found and tracked. For the foreseeable future, none that big are headed our way. NASA has identified and tracked almost all of the nearby asteroids of a size that would cause world-altering damage if they ever struck Earth. Scientists will then watch to see how the asteroid's trajectory changes. The golf-cart-size spacecraft will travel to an asteroid that's more than 6 million miles away - and poses no danger to Earth - and ram into it. In the first real-world test of a technique that could someday be used to protect Earth from a threatening space rock, a spacecraft is scheduled to blast off from Vandenberg Space Force Base in California on Tuesday at 10:20 p.m. NASA is about to launch an unprecedented mission to knock an asteroid slightly off course.
