15.06.10: Found: Lunokhod 1.

NASA has located an old friend on the lunar surface; Lunokhod 1, which landed on the lunar surface in 1970 and fell silent after 11 months of service. A Soviet unmanned rover, Lunokhod 1 delivered some first rate science. Remember, the Apollo astronauts stayed on the lunar surface for a period of time equivalent to a weekend camping trip. With its old school tech, Lunokhod 1 is decidedly steam punk in appearance. Fans of this space will also remember its sister rover Lunokhod 2, purchased by Richard Gariott for $68,500 in 1993. Both were imaged and recovered by the Lunar Reconnaissance Orbiter recently, and now scientists are recruiting the rovers to conduct science once again.  Lunokhod 1 was equipped with corner cube prisms, which reflect laser light back at exactly the direction that it came from. On April 22nd of this year, scientists at the Apache Point observatory in New Mexico fired (you always “fire” lasers!) laser pulses of light via the 3.5 meter telescope and were surprised with the results; more than 2,000 photons were successfully gathered on the first try. In fact, the reflectors on Lunokhod 1 are now brighter than on Lunokhod 2, which may be a scientific mystery in and of itself. Scientists hope to use studies in how the Moon moves through space to search out any potential kinks in General Relativity. That’s right; in the true spirit of science, Relativity (and Gravity, for that matter) is still being run through the mill, over a century later. Thus far, reality, as always, looks to be firmly on the side of Einstein, with the help of a now stationary defunct Soviet-era rover!
