DART will demonstrate key technologies required for spacecraft to rendezvous with other craft, such as satellites, without human intervention. DART will combine key autonomous technologies to actually rendezvous with a target satellite during the mission. It is the first demonstration program selected by NASA's Exploration Systems Mission Directorate to develop technologies for the Vision for Space Exploration.

The prelaunch press conference, with NASA Launch Director Omar Baez, is Oct. 25, at 2 p.m. EDT, in the Building 840 conference room, VAFB. There will be question and answer capability from NASA HQ, Kennedy Space Center (KSC) and Marshall Space Flight Center (MSFC) for reporters.
