This is Hillary Livingston, a model maker, and she is touching up a future lunar base featured in “Beyond Planet Earth”, a new exhibit at the American Museum of Natural History. NASA chemists have even recreated the smell of lunar dust for those interested in smelling it. The AMNH is pretty famous for its tiny dioramas, and I just love that they are finally doing space ones.
