Lunar landing & crash sites 13KB

ssc files to position all* manmade objects which have landed on the moon. ssc also specifies a "Beginning" time for each object, so it only appears at the moment of landing or impact. Zip includes:
9 Apollo Lunar Module & Saturn IV B Booster crash sites (U.S.)
6 Apollo manned landing sites (U.S)
14 Luna landing & crash sites (U.S.S.R.)
2 Lunokhod end-of-mission sites (U.S.S.R.)
5 Ranger crash sites (U.S.)
7 Surveyor landing & crash sites (U.S.)
4 Lunar Orbiter crash sites (U.S.)
1 Lunar Prospector crash site (U.S.)
1 Hiten crash site (Japan)

Total 49 crash & landing sites, 29 destroyed.
There are 2 sets of ssc's in the zip, you can also view the craft as "asteroids" in Celestia, as it makes their positions easier to see.

* When I say "all", I mean all that it was actually possible to get the impact coordinates for. Details of the 9 other lunar missions which did crash, but for which no coordinates were available can be found in the zip file. A few other missions actually missed the moon entirely


Luna 9 was the first manmade object to soft-land on the Moon's surface & transmit pictures back to Earth.

The Apollo LM Descent Stage, is the part that was left behind when the Astronauts returned to the Command module from the Lunar surface. They all remain on the Moon's surface today, and will be there for millions of years to come.

The full Apollo LM is the full Apollo Lunar module, which appears as it would have looked on the Moon's surface, while the Astronauts were there. The top part (Lunar module ascent stage) carried the Astronauts back to the Command module after their moonwalks, and was subsequently crashed into the surface of the moon again, to provide seismic impact data on the Moon's interior.

Lunokhod 1 & 2 were deployed from Luna 17 & 21, after their landings on the lunar surface.

Lunas 16, 20, 23, and 24 were of very similar design, and were to return samples from the surface of the moon in hermetically sealed capsules. All attempts were succesful, apart from Luna 23 which was damaged during landing. There are 2 models, one showing the craft in full on the surface, and one showing it after the return stage had left.

Luna 13 was the second manmade object to soft-land on the Moon's surface, and the first to carry out chemical soil analysis.

The ssc file for the Infrared Space Observatory specifies Earth centred, and Earth-Moon Barycentric elements. Compared to my own xyz file, the Earth centred elements seem to be more accurate.

The zip file contains 3 models of the Space Shuttle Atlantis, with the cargo bay closed, open, and a model of it at launch. Zip also includes an ssc to place the launch model at the Kennedy Space Center. You can use the orbital models whatever way you want!

HEALTH WARNING: The Helios UAV model has a HUGE file size, and will probably appear very jerky while viewing. You should expect around 5-10 FPS, even with a very fast PC and graphics card.

Shenzhou V 1KB

Orbital elements are fictional- modified Skylab orbit.
Shenzhou V was launched on Wednesday, October 15th 2003, with China's first man in space aboard- Yang Liwei. The first "taikonaut" orbited Earth 21 times, before landing safely in Inner Mongolia, after what was described by Chinese officials as a flawless mission.
Three cheers for China!
