Live coverage: Cygnus supply ship readied for station departure

Using 21st century images taken by NASA’s Lunar Reconnaissance Orbiter, scientists have reconstructed the view Neil Armstrong had outside the window of the Apollo 11 lunar module as he guided the spacecraft to a safe landing site on the moon 50 years ago.
