Exploration of Moon
The moon, Earth's closest celestial neighbor, has been an object of wonder and mystery since time immemorial.
Scientific missions over the centuries have peeled away layers of that mystery, but the moon continues to harbor many secrets. NASA's latest foray into lunar exploration is the Grail mission, a two-spacecraft expedition set to launch Thursday (Sept. 8) to map the moon's gravity in unprecedented detail.
