Attached to the southern rim are the co-joined craters Bonpland and Parry, which intrude into the formation forming inward-bulging walls.

[1] The surviving rim of Fra Mauro is heavily worn, with incisions from past impacts and openings in the north and east walls.

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 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.

By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Fra Mauro.
