Featured Facts

The American space program is looking toward future manned flights to the moon after nearly 50 years since the last NASA mission.  

Many people can recall when the first time human steps touched the lunar surface.  On July 16, 1969, Apollo 11 was launched with astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins aboard.

Days later, Armstrong and Aldrin landed the lunar module, named “Eagle,” on the moon’s surface.  The landing did not go quite according to plan, but the two astronauts made manual adjustments as they descended.

Both of the moon walkers left footprints on the lunar surface.  These will remain visible indefinitely because of the moon’s lack of wind.
