  • In this interesting close-up photograph of the crater which is now officially known as Guest, there's another curiosity to investigate. It's the so-called "alien spaceship" north-northeast of Guest (and of its somewhat larger companion). That "alien spaceship" (which is nothing more than a ridge on the floor of a not-so-extraordinary looking crater) looks somewhat needle-shaped on low-resolution photographs. This odd needle-like appearance was the start of a hoopla on the internet and on YouTube, because some freak invented a story about an unknown Apollo mission ("Apollo 20 ") which landed not far away of that "alien spaceship". And to make things much more complicated, he came up with the "proof " of the discovery of the corpse of an alien girl inside that needle-shaped "spaceship". That girl seems to be known as the "Mona Lisa of the Moon" or something... Research: Danny Caes


There are several orbital photographs of crater Guest in the LPI's online Apollo galleries (and also of the so-called "alien spaceship" NNE of it).

High-albedo crater west of Fermi, north of Iszak.

Additional Information

About the so-called "alien spaceship" immediately north-northeast of Guest and of its somewhat larger companion, see the Wikipedia-page Apollo 20 hoax.
The LM of the not-existing "Apollo 20 " landed near the needle-shaped ridge in the unnamed crater immediately north-northeast of Guest and its larger companion. It is interesting to explore the true appearance of that "needle-shaped extraterrestrial spaceship" on the Hi-Res NAC frames in the online LROC Act-React Quick Map !
It doesn't look that extraterrestrial !
