According to NASA, this is like a batting practice, but the risks are still high. If the impact fails, NASA's "impacter" will be out of orbit. If the impact is successful, critical data will be obtained to help NASA deploy ahead for real asteroid impact.

NASA plans to intercept the Didymos asteroid system when it is within 11 million kilometers of the Earth (compared to an average distance of 384,000 kilometers). According to the DART project website, the NASA satellite will not reach its target until October 2022. It will then strike an asteroid in the Didymos dual planetary system at a speed of nearly 6 kilometers per second.

The total cost of the project is expected to be around $69 million, which includes the cost of launching services, which will be managed by NASA's Kennedy Space Center's launch service. SpaceX's participation in the DART project means that the partnership between SpaceX and NASA has completely surpassed the scope of performing commercial load and replenishment tasks at the International Space (ISS) station.
