air and space museum, DC

May 12, 2010

The National Air and Space Museum is loaded with exciting information on the subject, but two things stood out for Logan.  First, the Sputnik (replica) on display is actual size at 23″ in diameter.  Logan was outraged at its tiny size!  The other thing that knocked his socks off?  The Mars wristwatch, designed to keep time at 24 hrs and 39 minutes per day, so that Mars mission earthlings can stay in synch with their rovers on the planet surface.
