NASA’s double asteroid redirection test mission will be launched in November </ P >

<

p > dart mission, managed by the Planetary Defense coordination office, involves sending two satellites to relatively close celestial bodies, known as the Didymos binary system. It will hit a large asteroid with a diameter of about 780 meters and a “small satellite” with a diameter of 160 meters</ p>

<

p > since this “small satellite” is a more typical type of celestial body that may threaten the earth (there are more asteroids of this size and are not easy to observe), scientists will test the possibility of hitting it at a speed of nearly 15000 miles / hour to intercept one. This will change the speed of the “small satellite” by only a few percent, but enough to have a measurable impact on its orbital period. Understanding the exact extent will help any future asteroid deflection mission</ p>

<

p > a supporting spacecraft liciacube (a light Italian cube satellite used to photograph asteroids) has just completed its final test last week and will be launched shortly before the operation. It will try to fly over at the moment of impact and capture “the resulting ejecta and possible new impact craters”</ p>

<

p > to be sure, this is a very exciting and interesting task. After having to postpone the original launch window this summer, November 23 will mark the first day of the new launch window. Dart plans to take SpaceX’s Falcon 9 to launch from denburg Air Force Base in Southern California at 10:20 p.m</ p>
