Crater Fra Mauro ( lat. Fra Mauro ) - the remains of a large ancient impact crater in the area of the northeast coast of the Poznan Sea on the visible side of the moon . The name was given in honor of the Venetian cartographer Fra Mauro (XV century) and approved by the International Astronomical Union in 1935. The formation of the crater dates back to the preectarian period [1] .

Crater Description
Bonplan and Parry craters adjoin the southern part of the Fra Mauro crater; in the south-west of it is the Poznan Sea [2] . Selenographic coordinates of the center of the crater , diameter 96.8 km [3] , depth 830 m [4] .
The crater Fra Mauro has a polygonal shape and is almost completely destroyed. The rampart has been preserved in the southern, southeastern and northeastern parts, the remaining parts of the ramparts are almost equal to the surrounding area. The southern part of the rampart has depressions formed by Bonplan and Parry craters. The bottom of the crater bowl is covered with basaltic lava flows and marked by many small craters. The bowl is cut in half by Parry furrows , passing through it from south to north. In the center of the bowl is the small satellite crater Fra Mauro E. The area surrounding the crater and partly the bowl of the crater are covered with breccia formed by rocks ejected during the formation of the Sea of Rainy basin. Samples of this breccia were collected and delivered to Earth by astronauts Alan Shepard and Edgar Mitchell during the Apollo 14 expedition (see below).

- Temperature anomalies during eclipses were recorded in the Fra Mauro D satellite crater. This is explained by the fact that such craters are small in age and the rocks did not have time to become covered with regolith , which has a thermally insulating effect.
- Satellite craters Fra Mauro A and B are included in the list of craters with dark radial stripes on the inner slope of the Association of Lunar and Planetary Astronomy (ALPO) [5] .
Spacecraft landing locations
- The crater area of Fra Mauro was the target of landing the Apollo 13 lunar module.
- On February 5, 1971, approximately 40 km north of the crater Fra Mauro, at the point with the selenographic coordinates of , landed the lunar module Antares of the Apollo 14 expedition.
