NASA launches DART asteroid mission to destroy a spacecraft to (potentially) save planet Earth

VANDENBERG SPACE FORCE BASE, Calif.– NASA has actually introduced its first planetary defense mission to practice what the agency may do if world Earth were threatened by a wayward asteroid.The firms Double Asteroid Redirection Test (DART) mission introduced at 10:20 p.m. regional time on Tuesday night, Nov. 23 (1:20 a.m. EDT, or 0620 GMT Nov. 24) from Space Launch Complex 4 here at Vandenberg Space Force Base in California. DART required to the skies atop a SpaceX Falcon 9 rocket, set to take a trip millions of miles out to smash into an asteroid in a planetary defense test. “Liftoff of the Falcon 9 and DART on NASAs very first planetary defense test to purposefully crash into an asteroid,” NASA spokesperson Marie Lewis said during a live broadcast of the launch.Related: NASAs DART asteroid-impact objective explained in picturesImage 1 of 9NASAs Double Asteroid Redirection Test, or DART, releases atop a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California, at 1:21 a.m. EST (0621 GMT) on Nov. 24, 2021.

The landing at sea marked the 95th time that SpaceX has actually recuperated an orbital class rocket booster.DART is now on its way to conduct a planetary defense test. The mission will utilize a “kinetic effect strategy,” to alter the orbit of an asteroid. In other words, the spacecraft will smash into an area rock to alter its direction. DART will impact a “moonlet” called Dimorphos that orbits around a much larger asteroid Didymos and the objective teams intends to shorten its orbit around Dimorphos by a number of minutes.

This asteroid system “has no chance of affecting the Earth whatsoever,” astronomer Amy Mainzer, who is the principal detective of NASAs Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) mission and who specializes in identifying populations of asteroids and comets, informed Space.com.Its “an exceptionally not likely scenario,” Mainzer stated. There is the possibility that one day there might be an asteroid that poses severe risk to Earth and its inhabitants. This test will reveal NASA how a kinetic impact strategy may work versus an asteroid that does pose a danger. If in the future, a large asteroid were determined that threatened Earth in some way, NASA might theoretically send out a spacecraft like DART to smash into it and press it in a different direction.Right now, no such threatening asteroid is known. As both Zurbuchen and Mainzer pointed out, scientists have actually only categorized about 40% of all near-Earth things. Now, researchers have actually cataloged approximately 90% of all near-Earth asteroids that are as large as the space rock that erased Earths big dinosaurs millions of years back, Cristina Thomas, a DART Observations Working Group Lead, told Space.com. There stay numerous smaller sized space rocks that have yet to be recognized. The key aspect of safeguarding planet Earth versus rogue space rocks is time.
