Circus on the Moon

As I have been highlighting this week, today, July 20, is the 40th anniversary of the first moonwalk. To mark the occasion, the crew of Apollo 11 - Neil Armstrong, Buzz Aldrin and Michael Collins - visited with President Obama, and astronauts on the International Space Station, showing hospitality for the 7 Space Shuttle Endeavour astronauts currently visiting the station, fixed a broken toilet. Houston, the Eagle has landed.
