NASA's final shuttle launch has come and gone. And the image of a shuttle blasting off into space is now a distant memory.
But guess what? NASA is in business and still launching stuff into space.
NASA's moon research mission called "Grail" is off to a good start.
This morning, two lunar orbiters attached to a rocket launched from Cape Canaveral, Florida.
The crafts, Grail-A and Grail-B, will eventually part ways from the delta rocket and pass over formations on the moon's surface.
Scientists are trying to get a better understanding of how the moon formed and how it's evolved.
Oh and just in case you were wondering. "Grail" stands for "Gravity Recovery and Interior Laboratory"
Sounds fancy!
