The UFP Aerospace Museum-Smithsonian Annex was a large facility which was located on the surface of Luna at Tranquility Base in an area known as the Sea of Tranquility.
History and specifics[]
Amongst the many attractions located within the annex was the well-preserved site of the first manned lunar landing from 1969 which was maintained in zero-atmosphere conditions so that the centuries-old equipment and footprints could be preserved.
Also located at the museum was the Terran space shuttle Joshua, the UNSS Icarus and the transporter room of the USS Moscow. (ST reference: The Worlds of the Federation)
In the 24th century at the museum, tourists could examine the Apollo mission's Lunar Roving Vehicle and portions of the Lunar Excursion Module. Children could safely experience the lighter lunar gravity in a cushioned room nearby. (Last Unicorn RPG module: A Cadet's Guide to Sector 001 Earth)
