(CNN) - Robotic probes to make final crash
On Monday, NASA's twin Gravity Recovery and Interior Laboratory probes will crash into a mountain on the moon, ending a fruitful mission to study the surface and composition of the moon. The GRAIL probes have been making a high-quality map of the gravitational field of the moon, which give scientists unprecedented insight into what's below the surface and how the moon may have formed.
The impact will occur at around 5:28 p.m. ET. A scientist working on the project said the crash probably won't be visible from Earth.
