There was a thermal and micrometiorite sheild - http://jeffreyellis.org/tlmp/files/facts/lm_descent.gif. I think it was also intended to prevent the Ascent Stage thrust from getting into all the tanks etc on the Descent Stage - no BOOM. Propellant was vented, but then there was the pressurising gas and any residual oxygen in storage. I knew about the shield but thought it only covered the tanks, not the descent engine compartment in the center. The cutaway drawing you linked doesn't make that clear either. There aren't many pictures of the descent stage from above, but this one shows an open hole http://www.apollomissionphotos.com/apollo12/108ksc69p220.jpg There's a drawing of the hole in the descent module he http://www.space1.com/Spacecraft_Dat...t_cutaway.html Pat |

It would be fun to know where the boulder came from. Pat I remember reading somewhere about a proposed Tycho landing for one of the later Apollos, and Jim McDivitt, who looked at landing sites from a safety perspective, said "You guys are going to Tycho over my dead body." This was supposedly Apollo 19 or 20 (cancelled anyway). |

That one really shows how accurate Pete's landing was. They mentioned they had the Surveyor in sight as they were getting ready to land. In fact they probably didn't want to land much closer to it than they did for fear the exhaust of their descent engine would damage it or topple it over*. The way it was, the exhaust threw up particles of lunar soil that hit the Surveyor while going at high velocity, due to the lack of an atmosphere to slow them down, and "sandblasted" the side of it facing the LM. That's something they will have to look into if they ever build a Moon base. Bad enough on lunar vehicles parked at it, but hit a space-suited astronaut with it, and at the very least they are going to need a new helmet visor, because it would look like you took sandpaper to it. * It landed at a pretty severe angle the way it was: http://upload.wikimedia.org/wikipedi...n_the_Moon.jpg I was going to link to a NASA PDF about Surveyor-3 and Apollo-12, but it of course just crashed Firefox. How do you expect us to make it back to the Moon if we can't even send a PDF between two buildings? Pat |

... Now, that really would have been some place to land a LM at; the view from up there would have been something to see. I've always thought that one of the public relations failures of Apollo was they never went any place interesting enough to compete with the Bonstell paintings that many of us were familiar with. Trouble was, Bonestell (like everybody else) assumed that because there was no weather on the Moon, it would have high, sharp mountain peaks. That turned out not to be the case. -- Gordon Davie Edinburgh, Scotland "Slipped the surly bonds of Earth...to touch the face of God." |

TMA-1 is buried *under* the crater, you have to work out where from the magnetic anomaly map. It's the big shiny crystal thingy from The Sentinel that's sitting on top of a mountain... Anthony |

Trouble was, Bonestell (like everybody else) assumed that because there was no weather on the Moon, it would have high, sharp mountain peaks. That turned out not to be the case. He also assumed more interesting areas for the landings while Apollo selected flatter, safer sites. The high f/No of the camera to compensate for the bright surface also ment that the stars were not visible on the film. Maybe someone should have thought of shooting the ground and sky independently and splicing them in the printing. I think the opposite is true for Mars where I remember rolling deserts and nothing as interesting as we now know. Val Kraut |

Fortran programming for IRAS downlink processing. It's a bit symbolic for me to not have an astronaut in the image. I'd love a picture from the time the shuttle rendevoused with IRAS to repair it. Except for that bit that no shuttle mission ever did do that so there are no such photos. Sigh. Maybe an image of Huble as seen from the shuttle and I would switch to that. |

They'll claim that there was a secret recent manned mission to create the footprints. The mission was necessary to continue the cover up of the earlier mission fabrication, and had to be secret for that reason. Sylvia. |
