The twin lunar orbiters Ebb and Flow are being prepared for their final descent on Monday.
The two probes made up NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, an endeavor that produced the highest-resolution gravity field map of any celestial body. To round off the mission both probes will he sent on a collision course which will see them smashing in to a lunar mountain, however no images of the event will be captured due to the region being in shadow at the time of impact."It is going to be difficult to say goodbye," said principal investigator Maria Zuber. "Our little robotic twins have been exemplary members of the GRAIL family, and planetary science has advanced in a major way because of their contributions."
Twin lunar-orbiting NASA spacecraft that have allowed scientists to learn more about the internal structure and composition of the moon are being prepared for their controlled descent and impact on a mountain near the moon's north pole at about 2:28 p. m. PST (5:28 p. m. EST) Monday, Dec. 17.
