Hi All,
I am not sure whether this is of interest to the community, but next year will see three rather significant 50th anniversaries in unmanned lunar and interplanetary spaceflight, those of Luna-1, the first probe to escape the gravitational field of the Earth (lunar impact intended), Luna-2, the first probe to actually hit the Moon and Luna 3, the first probe to image the Moon's far side. Luna-1 was launched on 2nd January 1959 and flew by the Moon on the 4th of the same month at a distance of 6000 km on its way to heliocentric orbit. http://nssdc.gsfc.nasa.gov/nmc/masterCatalog.do?sc=1959-012A Luna-2 was launched on the 12th of September of the same year, hitting the Moon on the 14th in the Palus Putredinus region (0 degrees longitude, 29 degrees N latitude) near the crater Archimedes. http://nssdc.gsfc.nasa.gov/nmc/masterCatalog.do?sc=1959-014A Luna-3 was launched less than a month later on 4th October (the second anniversary of Sputnik-1), swung around the Moon to image the far side on the 7th and transmittted its data to the Earth by the 18th. http://nssdc.gsfc.nasa.gov/nmc/masterCatalog.do?sc=1959-008A I don't know about you but I'm thinking of raising a glass of champagne a day later than New Year's Day in honour of Korolev and his merry band of pioneers. Happy Holidays to All, Tolis. |

For those vehicles that impacted the moon, it'd be interesting to image the impact sites regardless of the vehicle itself being spread in a very thin layer of deposited aluminium, steel and copper vapour as a thin film across thousands of square metres of regolith. Has such a man-made impact site ever been found, on the moon or anywhere else? I can't think of any
