"Earlier in the LRO mission, the Apollo 13, 14, 15 and 17 impact sites were successfully identified, but Apollo 16′s remained elusive. In the case of Apollo 16, radio contact with the booster was lost before the impact, so the location was only poorly known," NASA wrote in a statement.
ANALYSIS: Apollo 11 Site in Higher Definition
"Positive identification of the Apollo 16 S-IVB site took more time than the other four impact craters because the location ended up differing by about 30 km (about 19 miles) from the Apollo-era tracking estimate. (For comparison, the other four S-IVB craters were all within 7 km - about four miles - of their estimated locations.)"
LRO, which has been orbiting the moon since 2009, has now imaged all of the Apollo landing sites and booster impact sites.
