NASA DART MISSION LAUNCHES INTO ASTEROID HOW TO

That's tough, that's hard,' said Ed Reynolds, DART project manager at Johns Hopkins University Applied Physics Laboratory (APL). 'Our mission is to hit an asteroid at 15,000 miles per hour.

The spacecraft is comprised of a body smaller than a car (roughly 3.9 by 4.3 by 4.3 feet or 1.2 by 1.3 by 1.3 meters), two very large roll-up solar arrays (27.9 feet, or 8.5 meters long when deployed) and hypergolic and ion propulsion systems. The DART probe lifted off atop a SpaceX Falcon 9 rocket from Space Launch Complex-4E (SLC-4E) at Vandenberg Space Force Base in southern California.

What we're trying to learn is how to deflect a threat.' 'It's an intentional crash of a spacecraft into a rock. 'It's our first test of planetary defense,' Thomas Zurbuchen, NASA's associate administrator for science, said during a pre-launch briefing on Monday (Nov. The target, Dimorphos, poses no risk to Earth, but changing its orbit will test technologies and generate data to improve our capabilities when the next asteroid is discovered heading toward us. 24) will slam into a small space rock - the 'moonlet' of a larger asteroid - to slightly knock it off course. The Double Asteroid Redirection Test (DART) launched on Wednesday (Nov. It will see if the impact crater left by DART on Dimorphos (which it will get to within 200 meters of) has altered the trajectory of Didymos.- After billions of years of asteroids impacting Earth, NASA has taken its first step to strike back. Hera will take a close look at both Didymos and Dimorphos using lasers, a star-tracker, a thermal infrared camera and accelerometers. The European Space Agency’s “Hera” follow-up mission-due to launch in 2024 and arrive in early January 2027-is an asteroid rendezvous spacecraft designed to go see if DART worked. However, another space agency is sending another spacecraft to double-check. “After impact, we will use some of the same techniques, to determine how much Dimorphos has moved and ultimately, how successful we were.” “Thanks to the worldwide effort of observing this system from ground-based telescopes, we know what it looks like before the impact,” said Moskovitz. In October a bunch of ground-based telescopes around the world will be used to calculate Dimorphos’ new orbit. “We don’t want to, at the last minute, say, ‘Oh, here’s something we hadn’t thought about or phenomena we hadn’t considered.’ We want to be sure that any change we see is entirely due to what DART did.” “The before-and-after nature of this experiment requires exquisite knowledge of the asteroid system before we do anything to it,” said Nick Moskovitz, an astronomer with Lowell Observatory in Flagstaff, Arizona and co-lead of an observation campaign conducted in July 2022. So a lot of time has been spent getting to know the binary asteroids in detail. The DART Investigation Team has highly detailed computer simulations of kinetic impacts on asteroids, but it has no direct evidence of what would actually happen.

Scientists used this and other observations from the July campaign to confirm Dimorphos’ orbit and anticipated location at the time of DART’s impact. The sequence is sped up by about 900 times.

On the night of July 7, 2022, the Lowell Discovery Telescope near Flagstaff, Arizona captured this.
