IT House, Oct. 6, NASA announced yesterday that it has invited the media to launch a double asteroid guidance test. Allegedly, NASA has confirmed the target launch date for the Double Asteroid Redirection Test (DART) mission.

NASA is reportedly confirming that the target launch date is set at 22:20 PT on November 23, 2021. DART will launch the SpaceX Falcon 9 rocket into orbit and launch from Vandenberg Air Force Base in California.

IT Home knows that DART is a test of technology driven by planetary defense to prevent dangerous asteroids from hitting earth. DART will demonstrate for the first time the kinetic impact technology that changes the movement of asteroids in space.

The kinetic impact mission will send one or more large high-speed spacecraft into the asteroid’s path to determine if the asteroid’s direction can be changed to prevent it from colliding with Earth.

Although meteorites rarely hit the earth to cause serious damage to the ground, there have been disastrous effects on our planet in the past. DART’s target is the near-Earth binary asteroid (65803) Didymos.

Although the main body of Didymos is about 780 meters in diameter, the secondary celestial bodies (or “small moons”) are about 160 meters in size; this is more typical for the size of most likely asteroids. Great threat to the world.

The Dual Asteroid Orientation Test (DART) mission was directed by NASA at the Johns Hopkins Applied Physics Laboratory (APL) and supported by several NASA centers: Jet Propulsion Laboratory (JPL), Goddard Space Flight Center (GSFC), Johnson Space Center (JSC) , Glenn Research Center (GRC) and Langley Research Center (LaRC).

The DART mission is currently managed by APL, managed by NASA’s Marshall Space Flight Center’s Solar System Exploration Program and is the responsibility of NASA’s Planetary Defense Coordination Office and the Planetary Sciences Division of the Science Mission Council at NASA’s headquarters in Washington. is in the process. , DC.Return to Sohu to see more
