Not long after midnight central time tonight, the rover known as Curiosity will land on Mars.

It will take the rover seven minutes to get from the Mars atmosphere to the planet's surface. But because it takes about twice that long for signals to travel from Mars to Earth, scientists won't know anything about the landing until after it's already over.

Houston now has one fewer problem to worry about.

Moon dust apparently smuggled years ago from Johnson Space Center is now back in Houston - from St. Louis.

Twenty-five years ago, the Space Shuttle Challenger broke apart shortly after liftoff, killing all seven crew members on board.

Here in St. Louis, the Challenger Learning Center is offering a variety of programs honoring the Challenger crew and their families.
