DART (satellite) Arms Regulations. On May 15, 2006 NASA released a public summary of the DART mishap investigation board report (NASA press release). NASA revealed that a critical navigation failure occurred when the DART and MUBLCOM spacecraft were about 200 meters apart, which precluded the full activation of the AVGS and allowed DART to approach MUBLCOM without accurate ranging information. A later failure of the collision avoidance system, which was relying upon inaccurate position and velocity information, allowed DART to ultimately collide with MUBLCOM at a relative speed of approximately 1.5 meters per second. Both spacecraft survived the collision without apparent damage.
