Fra Mauro
The crater Fra Mauro and associated Fra Mauro formation of the Moon are named after him. The Apollo 13 lunar mission was intended to explore the Fra Mauro formation, but – due to the explosion aboard the spacecraft – Apollo 13's crew had to return to Earth without landing on the Moon. The formation was instead explored by astronauts Alan Shepard and Edgar Mitchell of the Apollo 14 mission in February 1971.
