writes "According to a July 3, 2013 story in SpaceRef, NASA has issued a Request for Information (RFI) concerning various commercial endeavors to create robotic lunar landers. NASA appears to be interested in assisting in those projects with a view of using the resulting vehicles for its own exploration plans.
Officially, thanks to a mandate by President Obama, NASA is not planning its own crewed mission to the moon. However the space agency seems to be interested in supporting, in some way, a commercially run lunar base. Joint robotic lunar landings might be seen as the start of such an effort."Link to Original Source
