Ejecta in Tycho Crater

January 3, 2011
Tycho crater is a Copernican age crater (85 km diameter) located at 43.3°S, 11.2°W. It is named for the 16th century Danish astronomer Tycho Brahe and is one of the most visible features on the near side of the Moon. Its ray system is so obvious and widespread that Apollo 17 astronauts sampled its ejecta, over 2000 km away from the crater! Scientists dated the Tycho samples at about 110 Ma. We also have surface views of Tycho's ejecta blanket taken by the Surveyor 7 soft lander.
