PARIS — NASA has revived a robotic lunar rover mission by selecting Blue Origin to deliver it to the moon’s south pole in 2027. Blue Origin will use its Blue Moon Mark 1 lander to transport VIPER. On May 7, though, it said it would not pursue a commercial partnership and instead explore unspecified “alternative approaches.”The new CLPS task order, called CS-7, had not been publicly disclosed before the Blue Origin award. The base award covers only work to design accommodations for VIPER on Blue Moon and to get it off the lander and onto the surface after touchdown. NASA states that option would be exercised after completion of the design work as well as a successful landing of the first Blue Moon mission.
