SpaceX launched a double moon mission today (Feb. 26), sending a private lunar lander and a NASA orbiter to hunt for signs of water on Earth's nearest neighbor.

The space exploration firm is scheduled to launch its six-legged Nova-C moon lander, Athena, on Wednesday as part of NASA's $2.6 billion Commercial Lunar Payload Services (CLPS) initiative. Athena is scheduled to launch aboard SpaceX's Falcon 9 rocket from NASA's Kennedy Space Center in Florida.

A dishwasher-sized NASA satellite was launched into space from Florida on Wednesday to identify where water - a precious resource for lunar missions - resides on the moon's surface in places such as the permanently shadowed craters at its poles.
