Fra Mauro
The area north of Fra Mauro crater was the intended landing site of the ill-fated Apollo 13 mission, which was aborted after an oxygen tank aboard the spacecraft exploded. The crew later returned safely to Earth. The next mission, Apollo 14, landed at Fra Mauro. The Apollo 14 crew (Alan Shepard and Edgar Mitchell) sampled breccia that had been deposited here by the Imbrium basin-forming impact, and which partly covers Fra Mauro. This rough debris blanket of ejecta is referred to as the "Fra Mauro Formation".
