It sent back data until the last possible moment, struggling against the atmospheric forces that would soon vaporize the spacecraft into dust. Then, it was gone. Cassini's perfectly executed dive last week shuttered one of our few windows to the solar system.

If you can send a spacecraft to the moon and loop around our natural satellite one time, or—even better—gently set a rover down on the lunar surface, there could be money in it for you. $4.75 million, to be precise.

If humans are ever really going to make it to Mars, we're going to need a bigger boat. Today's spaceships are built for short hauls to and from the International Space Station, a mere six or so hours away.

A lander like this will fly in Moon Express's first launch, slated for later this year. It can carry up to 66 pounds of equipment and scientific instruments to the lunar surface. Or it can stay in orbit or travel deeper into space.

On my first day of spacewalk training in NASA's Neutral Buoyancy Laboratory at the Johnson Space Center, the future loomed in front of me as bright as the heavens I had hoped to reach. I wanted to master the fundamentals and, like all astronauts, I knew that spacewalk proficiency was the quickest path to that coveted first flight assignment.
