This screenshot from NASA’s Eyes on the Solar System 3D visualization tool shows Lunar Flashlight making its close approach with Earth late on May 16. The CubeSat was expected to pass about 40,000 miles (65,000 kilometers) from our planet’s surface over Brazil’s east coast on May 17.

NASA’s small Lunar Flashlight spacecraft, sent to the moon last year to search for water ice deposits at the moon’s south pole, will not be able to complete its science mission after a problem with the probe’s propulsion system.
