This press release tells us that the Apache Point Observatory is now getting laser ranges to the newly recovered Lunokhod 1. The reflected signal is twice as strong as that from Lunokhod 2 and this new target means there are now five functioning reflectors on the moon.

Huh. Very cool! Score another victory for LRO!
Kind of amazing that they've been trying for almost 40 years to get a laser reflection off of it, yet the reflector was apparently very well-oriented with respect to the Earth. Of course, they did state the detection levels in terms of photons returned, and snagging 2000 is seemingly remarkable performance; the SNR for this sort of thing must be quite low indeed. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.
