A map of the Moon's surface that astronaut Dave Scott used to navigate the lunar rover during the Apollo 15 mission has sold for $40,000 at RR Auction.
The remarkable lot is marked with Scott's own notes on the geographic features of the area. He's signed it on the bottom left side.
Scott explained in a letter of provenance: "This map was used for landmark recognition during navigation from the Lunar Module to the stations of exploration on each EVA and in emergency return to the LM in the event the Lunar Rover was unable to return for any reason…
"The Map contains traces of lunar dust and was exposed to the temperature extremes, radiation, and Solar Wind on the surface of the Moon."
The map is the latest historic piece from Scott's personal collection to come to auction. Last year a watch he wore on the Apollo 15 mission realised a record $1.6m.
The auction included a huge range of other memorabilia, including a Christmas note from Queen Elizabeth II to Prince William that achieved $1,931.
The lot was consigned from the collection of an aide to Princess Diana.
It's said to have accompanied an advent calendar and reads: "William, I hope you enjoy opening this each day. From Granny".
