CSM codename was Blackjack. Because of the urgency and rush of the mission re-task no one bothered to actually change it.... Hey it's MY story... Artistic license, blah blah blah... :-D Neil Armstrong runs for president right after apollo 11s return with the vision of sending astronauts to mars in 10 years. Using multiple saturn 5 launches and Nerva they pull it off with time to spare. Niel wants to be the first man on mars but looses. The USSR is devastaed end ends communism right after the mars landing.... |

A *better* Apollo 18 Plot Synopsys...
The one flaw I thought would be glaring and kill the whole idea is the inability of LEM/CSM to reach high enough angle orbits to actually carry off a lunar polar landing mission. Was this ever really seriously considered? There was extra fuel in that in a problem the CSM could go down and rescue a LM with a failed Ascent Engine that wouldn't restart after initial liftoff. Also some extreme cases where multiple phasing orbits would allow the CSM to rescue the LM crew. LM-10 and sub had the stretched descent tanks to permit longer stay plus the rover. Could drop the rover since another LM will bring a pressurized one and maybe make the tanks a bit larger. Ascent Propulsion had crossfeed between RCS and Ascent Propulsion and backup fuel for RCS system failure. Cutting margins should make things work if indeed it was needed. I don't think polar landing was fuel constrained - the real problem was hazard avoidance in the polar lighting conditions. The CSM also had mass allowance for mapping cameras etc. Swap out for fuel or just make it lighter. So by making some engineering changes, mission groundrules your mission seems plausable. The real problem is maintaining the LM in lunar orbit and docking with it after years. The LM used battery power. Ascent stage had 12 hours and then it's done. So you have to either add solar arrays or maybe an RTG to keep the LM Ascent stage going. If you do this you could have ground station managing orbit maneuvers to keep it alive and available. Next problem is the Mean Time Between Failures for the 1960s LM guidance units, and the number of cycles you get get out of the RCS thruster valves. Remember this was planned for a several day mission. Youo could cut the timeline and resort to things like "The thing just won't quit - the Grumman Iron Works comes through again" Val Kraut |

The CSM, with me as the sole surviving astronaut, returns to Earth. That's why I proposed the necessity of the "stretch" Saturn V. ;-) No respect, I get no respect at all...

Pat I dunno, IIRC my local paper was running Apollo 11 stories and the Mary Jo Kopechne story on the same front page. If I was RFK and I was president I'd be doing *something* to keep the public imagination away from my family.... Nixon was pretty much going to ditch the manned space program after the slated Apollo missions, but thought it would look like he was being vindictive against JFK for the 1960 election, so we ended up with the Shuttle. Just like Nixon being the only person who could go to China, RFK would be the only person who could say that we did just what his late brother said we would do in his speech, and now it was time to move on to other challenges. LBJ was always a lot more of a space cadet than JFK ever was anyway. Pat |

It would be fun to see it try that without landing legs. :-D Pat |

Could a "Block 3" LM been outfitted with higher resolution landing radar to provide hazard avoidance? Was the radar technology in 1970 (you have to go back a few years to what was available BEFORE the mission is actually launched to use that tech), sufficient to provide this capability? Wow, talk about getting lucky for pulling a plot line completely out of one's ahem, you know where.... The real problem is maintaining the LM in lunar orbit and docking with it after years.

Remember this was planned for a several day mission. Good point. New plot gimmick. In the original mission plan of Apollo 20 the LM/AM was to remain in orbit for awhile conducting surveys over the polar regions via remote control because of its uniquely high angle orbit. The first LM to to have its electronics powered by a set of RTGs, evolved from the ones used in ALSEP. Youo could cut the timeline and resort to things like "The thing just won't quit - the Grumman Iron Works comes through again" Probably shortest 'realistic' time frame is 1 year + a few months.

Was the radar technology in 1970 (you have to go back a few years to what was available BEFORE the mission is actually launched to use that tech), sufficient to provide this capability? No - the landing radar gave overall slope and distance. Initials guidance calculations were based on IMU data - IMU data became less accurate due to drift as the landing proceeded. Landing Radar data was than used and weighted more heavily than the IMU based calculations in the terminal phase. The real problem is Hazard avoidance - small rocks or craters big enough to tilt the vehicle, hit the engine bell etc. They're still working that problem LIDARs today. LM got you above the landng sight and the astronaut accepted or redesignated to a clear area. In the poles you get poor light with long shadows that mask hazards. One of the reasons polar missions were ruled out early in the game. If you land the Taxi first the crew can pick smooth sppots and place beacons for the cargo and habitat landers - hopefully away from each other and the taxi- LM-6 exhaust kicked up enough dust to do some sandblasting on the Surveyor they visited.

I suppose some bright landing lights flipped-on at N feet was either too heavy or pulled too much power? Too simple?
