NASA recently signed a $ 69 million startup contract with SpaceX to facilitate dual asteroid turn-around (DART) missions. If all is planned, DART will release False 9 on a Space Launch Center 4E in Vandenberg Air Force Base in California in June 2021. The DART command is to get the asteroid deal with a stretch and measure or if it is possible to change his job.

As part of the Asteroids Impact and Deflection Assessment (AIDA) project in conjunction with the European Aviation Administration (ESA), DART used an artificial satellite to kill and lower the smaller asteroid in the Duma Planet system. The largest S-form asteroid in the Second Planets of Didymos is the name Didymos A, which is about 780 meters, and the smaller one is Didymos B. The composition is unknown and the diameter is approximately 160 meters (530 feet).
Initially, the ESA has contributed to the project through a post-impact observation mission called AIM (Asteroid Impact Mission). AIM can measure the effect of impact. Unfortunately, this mission could not find enough finds. It appears that ESA has decided to redo this mission: the European Space Agency has just named a new space phase that calls it AIDA the role of a AIM mission. Four years after the influence of DART, AIDA will take over by Didymos by 2020. This allows space problems to judge the orbits, rotations and pubs to the DART space problem. By comparing the ratings of two spatial and post-spatial characters, it can have the effect of & # 39; an exact character is precisely determined.
According to NASA, this is like a battle practice, but the risk is even higher. If the impact fails, NASA & # 39; will impact & # 39; be out of & nbsp; job. If the effect is successful, get critical data to help NASA use for real asteroid impact.
NASA is planning to destroy the Didymos asteroid system when it is within 11 million kilometers of the Earth (compared to an average distance of 384,000 km). According to the website of the DART project, the NASA satellite will not reach its target until October 2022. It will get an asteroid in the Didymos double planetary system at a speed of nearly 6 kilometers per second.
