NASA has spent $450 million designing and building a first-of-its-kind robot to drive into eternally dark craters at the Moon’s south pole, but the agency announced Wednesday it will cancel the rover due to delays and cost overruns.
“NASA intends to discontinue the VIPER mission,” said Nicky Fox, head of the agency’s science mission directorate. “Decisions like this are never easy, and we haven’t made this one, in any way, lightly. In this case, the projected remaining expenses for VIPER would have resulted in either having to cancel or disrupt many other missions in our Commercial Lunar Payload Services (CLPS) line.”
NASA has terminated science missions after development delays and cost overruns before, but it’s rare to cancel a mission with a spacecraft that is already built.
