Following several more changes to the orbit, the spacecraft descended to the lunar surface on 6 November and landed in the southernmost portion of Mare Crisium.
During landing in "unfavorable" terrain, the lander's drilling device was evidently damaged, preventing fulfillment of the primary mission, the return of lunar soil to Earth.
Scientists devised a makeshift plan to conduct a limited science exploration program with the stationary lander.
The spacecraft evidently tipped over upon landing, perhaps due to higher than nominal vertical and/or horizontal velocities at touchdown.
