I thought that it was time to start up a discussion of what we know, or would like to know, about the Soviet Luna Missions. To start off, I have heard many a reference to the landing system utilized by the early landers, such as Luna 9. However, I have yet to find a report, or even a diagram, that shows the sequence of events, or such details as the air bags. If such references do not exist, I hope that some of the UMSF community have Russian contacts that could lead us to the source material before it ends up in the dust bin of history. In addition, I heard of an effort several years ago to obtain ALL of the imagery from Lunakhods 1 and 2. Does anyone know if that effort was able to secure that data? Also, as far as Lunas 15, 18 and 23, the sample-return missions that didn't quite make it home, are there any official reports "out there" that detail what actually occurred to those missions? Or will we have to wait for the high-resolution images from the LRO to determine their fates? Another Phil |

Luna 23 and Luna 18 were apparently damaged by hard landings. I am just speculating, but perhaps the landing radar was confused by surface boulders and the retros cut out a little early.
Luna 15, I guess they are pretty sure was a sample return, crashed too. Considering the complexity of a sample return, a first attempt (is this known for sure?) might have gone awry in any number of ways. Considering the US Ranger series, (but not the Surveyors!), probably not too surprising. |

Considering the US Ranger series, (but not the Surveyors!), probably not too surprising. I saw a drawing of Luna 15 circa 1992 from the aerospace group that used to put out annual reports on Soviet spacecraft and missions (could someone help me with the name, please? Thanks.). It looked exactly like Luna 16, which did land on the Moon and return some surface samples successfully to Earth just over one year later. Not a real surprise, but nice to know. This Web site has what it labels to be an image of Luna 15, but can anyone confirm this? http://www.aerospaceweb.org/question/spacecraft/q0196.shtml At least it wasn't a scenario out of the 1968 film Countdown where Luna 15 was really a desperate manned attempt to beat the USA and the Soviets ended up losing three cosmonauts. http://www.imdb.com/title/tt0062827/ The Soviets were also trying to beat Apollo 11 to the Moon and return with some surface samples before the US did as a sort of coup. No doubt rushing too fast in this part of the Space Race cost us all a little bit of a different place to study from the Moon. There is a very funny story created by Dwayne Day in 1999 detailing how Luna 15 was NOT an unoccupied vehicle: http://www.astronautix.com/astros/bormp504.htm Don P. Mitchell has an incredible collection of Soviet lunar probe images, including many from the two Lunakhods: http://www.mentallandscape.com/C_Catalog.htm This is not to ignore or downplay anyone else's collection of similar images, it's just that Mitchell appears to have the most I am aware of. There are already some other UMSF threads that discuss the Soviet lunar missions and have images from them as well: http://www.unmannedspaceflight.com/index.p...indpost&p=13362 http://www.unmannedspaceflight.com/index.p...findpost&p=9080 http://www.unmannedspaceflight.com/index.p...findpost&p=9101 http://www.unmannedspaceflight.com/index.p...indpost&p=11828 http://www.unmannedspaceflight.com/index.p...indpost&p=13688 -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |
