FTFA: Now the team can eventually pin down the changing shape of the lunar orbit to the millimeter to help test Einstein’s theory of general relativity.
There might be other reflective things on the moon, but I assume that this one is somehow special. I at least *hope* that the people searching for it know what they are doing
There are certainly other reflectors out there on the moon, that could and have been used for measuring the moon's distance--and for some time now. I can't imagine what could be special about this one, except for the quality, perhaps? Nah. What if it's not kosher for others to shoot lasers at the reflectors that other scientists use? The article ends there and is skimpy on details.
