NASA's Twin Moon Probes Set for Lunar Arrival This Weekend

"Grail-A and Grail-B won't be ready to start their science campaign immediately upon arriving at the moon. Rather, they'll spend another two months circling lower and lower, eventually settling into orbits just 34 miles (55 kilometers) above the lunar surface, researchers said....

...Researchers also want Grail to raise public awareness about the moon, and to help engage kids in math and science. To this end, special cameras aboard the probes will be used to encourage middle school students to participate in lunar research and follow along with Grail, during both its nominal mission and any extended campaign."
