Bruce Moomaw contacted Brad Jolliff, the PI, and learned a bit more about this proposal:
"We are planning a single lander, but this should not be considered a 'descope.' The MoonRise proposal for this New Frontiers opportunity was a new proposal. As such, we think (and have made the case) that we can accomplish the science objectives of the mission with a single lander and an appropriately selected landing site within the South Pole-Aitken Basin. With all of the remote-sensing information collected by recent and current orbital assets (SMART-1, Kaguya, Chang'e-1, Chandrayaan-1, and LRO), we can optimize our landing site both for science and landing-site safety considerations."
MoonRise will return 1 kg of samples. They will also be including a relay comsat, which is not exactly a surprise. They hope to put up a website on "Moonrise" later this month.
