NASA will provide live commentary of the scheduled lunar surface impacts of its twin Gravity Recovery and Interior Laboratory (GRAIL) spacecraft beginning at 2 p.m. PST (5 p.m. EST) Monday, Dec. 17. The event will be broadcast on NASA Television and streamed on the agency’s website.

The two probes will hit a mountain near the lunar north pole at approximately 2:28 p.m. Monday, bringing their successful prime and extended science missions to an end.

Commentary will originate from the control room at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif. Coverage will last about 35 minutes and include live interviews with GRAIL team members. GRAIL’s final resting place on the moon will be in shadow at the time of impact, so no video documentation of the impacts is expected.

Data from the GRAIL twins are allowing scientists to learn about the moon’s internal structure and composition in unprecedented detail. The two probes are being sent purposely into the moon because they do not have enough altitude or fuel to continue science operations.
