Combination of errors led to spacecraft hitting satelite

摘要

A series of technical and human errors prevented NASA's DART (Demonstration Autonomous Rendezvous Technology) spacecraft from completing its mission to rendezvous with a military satellite last spring, according to the findings of an investigation released in May. Scott Croomes, the NASA engineer who chaired the DART Mishap Investigation Board, said the mission's failure stemmed from a combination of spacecraft navigation errors and 'mis-steps' by the vehicle's NASA and contractor design teams.
