Scientists at NASA decided to test their ability to communicate via laser to the Lunar Reconnaissance Orbiter (LRO) by sending an image of the famous painting.
One of LRO's instruments, the Lyman Alpha Mapping Project (Lamp), detected enhanced concentrations of mercury and atomic hydrogen in the cloud from the demise of the twin spacecraft.
As the pair of probes took their final plunge, Nasa's Lunar Reconnaissance Orbiter (LRO) had been manoeuvred into the right place to see the spacecraft slam into an unnamed 2, 500m mountain.
