LRO has been sending us back images of various Apollo sites and of the Soviet Lunokhod rovers.
The Rovers had laser reflectors and the one from Lunokhod 2 has been used for returning signals from Earth. Now the other reflector from Lunokhod 1 has been found and laser beams
sent to it and reflected back to Earth.

NASA's LRO Team Helps Track Laser Signals to Russian Rover Mirror
Using information provided by NASA’s Lunar Reconnaissance Orbiter (LRO) instrument teams, researchers at the University of California San Diego successfully pinpointed the location of a long lost light reflector on the lunar surface by bouncing laser signals from Earth to the Russian Lunokhod 1 retroreflector.
The initial imaging of the two Russian rovers, Lunokhod 1 and 2 were made earlier this year by the Lunar Reconnaissance Orbiter Camera (LROC) team, led by Mark Robinson from Arizona State University in Tempe.
On April 22, Tom Murphy from the University of California San Diego and his team sent pulses of laser light from the 3.5 meter telescope at the Apache Point Observatory in New Mexico, zeroing in on the target coordinates provided by the LROC images and altitudes provided by the Lunar Orbiter Laser Altimeter.
“We quickly verified the signal to be real and found it to be surprisingly bright: at least five times brighter than the other Soviet reflector, on the Lunokhod 2 rover, to which we routinely send laser pulses,” said Tom Murphy, an associate professor of physics at the University of California San Diego. “The best signal we’ve seen from Lunokhod 2 in several years of effort is 750 return photons, but we got about 2,000 photons from Lunokhod 1 on our first try. It’s got a lot to say after almost 40 years of silence.”
Since Apollo deployed laser retroreflectors, astronomers have routinely used them track how the moon is slowly moving away from the Earth. This helps scientists develop a better understanding of the processes that are causing this motion, including what’s occurring inside the moon’s core and the tidal motions on the Earth.

What did they say, the best return signal from Lunokhod 2 has been 750 photons. That is a reflected laser beam bouncing back from the Moon some quarter of a million miles away and you catch 750 photons. Now they are excited about being able to catch 2000 photons, and I thought
my old flashlight with tired batteries was dim.

Lost Soviet Reflecting Device Rediscovered on the Moon

A long lost light reflector that was left on the surface of the moon by the former Soviet Union has been rediscovered by a team of American physicists after nearly 40 years using lasers beamed from Earth.
The French-built laser reflector was sent aboard the unmanned Soviet Luna 17 mission, which landed on the moon on Nov. 17, 1970 and released a robotic rover that roamed the lunar surface and carried the sought after laser reflector.
The Soviet lander and its rover, called Lunokhod 1, were last heard from on Sept. 14, 1971.
"No one had seen the reflector since 1971," said Tom Murphy, an associate professor of physics at the University of California San Diego. Murphy leads a team of scientists in a long-term effort to use laser reflectors to measure the shape of the lunar orbit and look for deviations in Einstein's Theory of General Relativity.
"We routinely use the three hardy reflectors placed on the moon by the Apollo 11, 14 and 15 missions, and occasionally the Soviet-landed Lunokhod 2 reflector – though it does not work well enough to use when illuminated by sunlight," Murphy said. "But we yearned to find Lunokhod 1."

Well another reason to look up. :-)
