We’re celebrating the 50th anniversary of Apollo 11’s historic journey to the moon.

When there are 16 sunsets every day, getting some shut-eye becomes a bit of an issue. Do astronauts get through it with some warm milk as they float?

In the 1960s, space food was either cubed or tubed, and it wasn't very appetizing. Today's astronauts have a more palatable array from which to choose. Where is it developed?

Some people don't believe a man walked on the moon. Others still think the Earth is flat. Are the Illuminati preparing the Earth to become an alien colony?

We know who won – top-runner SpaceShipOne. We know what the team receives for that accomplishment: $10 million and an obscenely gigantic trophy. But what about the story behind the contest? Learn about the rules, restrictions, red tape, test crashes, successful launches and the technological innovations that may get you into sub-orbit sooner than you think.

GPS is great, but it's kind of Earth-centric. If we have our hearts set on traveling to distant planets and faraway stars, then it's time to come up with a new navigation system. NASA, of course, has an idea.

On Earth, we have a constant supply of fresh air. But what happens in the tiny, confined cabins of spacecraft, like the space shuttle or space stations? How is oxygen supplied to the people on board?

By Craig Freudenrich, Ph.D.

In the confined cabins of spacecraft, like the space shuttle or space stations, carbon dioxide, which is toxic, poses a problem for astronauts. Keep reading to see how that CO2 is eliminated.

Showering every day is likely something you take for granted. But for astronauts on the International Space Station, it's not an easy task.

By Kristen Hall-Geisler

Humans have made it to the moon a number of times so we know how long the journey should take.

NASA and other agencies have been studying artificial gravity in hopes they will someday use it to help astronauts combat the effects of weightlessness in space. How close are we to that reality?

By David Warmflash, M.D.

Nobody's nose knows better than NASA's George Aldrich. He's the longest-serving member of the space agency's odor panel, which basically sniffs and smells everything that goes up into space.

NASA's historic Beach House on Cape Canaveral is the last place many astronauts visit before they blast off into space. Today it's full of mission memories and NASA artifacts.

By Mark Mancini

For the first time since 2011, NASA will launch astronauts into space from U.S. soil. It will also be the first time ever a private company will get them there.

By Mark Mancini

When you think of NASA, you probably think of an all-around professional organization. And you're right. But, those astronauts like to have a lot of fun, too.
