15 years ago, in 2011, NASA launched the twin GRAIL satellites aboard a Delta rocket from Cape Canaveral. The two satellites orbited the Moon for 15 months to map its gravity. During the mission, Sally Ride Science ran GRAIL MoonKAM, an educational outreach program that allowed students to request photos of the lunar surface from cameras on the satellites. NASA held a national contest to name the twin satellites. The winning names, “Ebb” and “Flow,” were suggested by fourth-graders at Emily Dickinson Elementary School in Bozeman, Montana. https://buff.ly/0WjS6w2 NASA illustration
