If you have recently signed up here to receive updates on the Lunar Rock visits to UVHS you may have read the article in the UVHS newsletter that said the samples had been collected by Apollo 18.
There was of course no Apollo 18 (apart from the in the film of the same name). The rock samples which will be at UVHS in January were collected primarily during the Apollo 17 mission by Eugene Cernan and Harrison Scmitt.
Plans for this special week in January are well underway. Sign up on the right column of this page to get updates on how you can join in.
