A few more words from the above linked article:
The $496 million Grail mission (short for Gravity Recovery And Interior Laboratory) will closely study the interior of the moon, from crust to core, and will map the moon's gravitational field in unprecedented detail. The three-month mission is expected to help scientists better understand the composition of Earth's natural satellite and its evolutionary history since it was formed 4.6 billion years ago.
