![]() ![]() Asteroid Bennu is claimed to be the most likely to do so. The agency then added the importance of testing the technique on smaller asteroid targets to develop further data for theoretically greater threats due to being more common.įurthermore, a celestial body of any significant size hitting the Earth is still extremely unlikely. The DART's target, Dimorphos, is significantly tinier than the Chicxulub asteroid that played a deadly role against the dinosaurs 66 million years ago. NASA clarified ahead of the launch of DART that there would be no known celestial body larger than 140 meters with a slight chance of hitting the Earth for the next century only about 40 percent of those asteroids have been known as of Oct. Johns Hopkins University played a special role in the DART mission Doctor Chabot, who leads the mission for NASA, also mentioned that the DART would aid the future positioning of the asteroids against the Earth.Īrtist's illustration shows the DART spacecraft approaching Dimorphous.ĪLSO READ: NASA DART Mission to 'Kill,' Deflect Asteroid At 15,000mph This September Astral Collisions Against Earth NASA officials wrote in a press release saying that after the final maneuver on September 25, a day before the impact, NASA's navigation team will be able to know the position of the target within 2 kilometers (1.2 miles), and added saying, "From there, DART will be on its own to guide itself to its collision with the asteroid moonlet autonomously."ĭoctor Nancy Chabot from the JHUAPL or Johns Hopkins University Applied Physics Laboratory, told BBC News, " DART is the first planetary defense test mission to demonstrate running a spacecraft into an asteroid to move the position of the asteroid ever so slightly in space." The space agency added that the DART would hit Dimorphos with a speed of 14,760 mph or 23 760 kph. According to NASA, it is about 7 million miles (9.6 million kilometers) from the blue planet and has no risk of impacting the Earth. The Dimorphos, DART's target, stands about 56 feet (170 meters) wide and paths its parent asteroid, Didymos, every 11 hours and 55 minutes. The test will serve as a "kinetic impactor" to change the orbit of an asteroid. Returning to its beginning, NASA's DART launched almost a year ago on November 24, 2021. ![]() Space fans can watch the live streaming of the historical event on space websites that will operate viewing. The spacecraft will make history when it crashes into the asteroid in the Earth's first ever planetary defense. NASA's Double Asteroid Redirection Test (DART) spacecraft will collide with an unfortunate asteroid named Dimorphos on September 26 at 7:14 PM EDT. ![]()
