MarkWhittington writes: Ever since President Obama foreswore interest in returning to the moon in his April 2010 speech at the Kennedy Space Center, lunar exploration has been on the back burner at NASA. According to a story at Space News, that may change starting around 2020 thanks to a project called RP15, the letters standing for "Resource Prospector," a rover designed to drill into the lunar regolith and collect samples for analysis. The rover, originating at NASA Ames Research Center, was recently tested on a simulated lunar surface at the Johnson Spaceflight Center south of Houston. RP15 was built by the same team at JSC that developed Robonaut 2, now being tested on the International Space Station, with the software being written at Ames. The tests at JSC involved the rover being controlled by engineers at NASA Ames, half way across the country in California.
