NASA has stopped trying to revive its Lunar Trailblazer moon orbiter, which went dark a day after its Feb. 26 launch.

NASA's Lunar Trailblazer ended its mission to the moon on July 31. Despite extensive efforts, mission operators were unable to establish two-way communications after losing contact with the spacecraft the day following its Feb.

After five months of trying to reestablish contact with the lost NASA Lunar Trailblazer, the agency has released a sad update: the mission is over.
