Lunar Orbit Station?
Concerning this return to the Moon project: would there be any
advantage of a waystation in lunar orbit? I mean, going beyond LOR-style missions to having a place to receive crews headed for the surface. Perhaps ascent craft could be dismantled in orbit to reassemble into an orbital platform? Or maybe the orbital platform could act as a fueling station for reusable landing craft? I would think that a precursor to landing on Mars would be a sizeable station orbiting above the test landing areas. Leaving as much of your junk in orbit made sense during Apollo, so wouldn't having more equipment in orbit be helpful on this go-round? |

A waystation in low lunar orbit makes little sense; such orbits are short- lived due to irregularities (mascons) in the lunar gravitational field, and would require considerable propellant to maintain. A waystation in Earth- Moon L1 would make more sense. But, *what* would it *do*? |

It isn't a stable position, so you're still going to need fuel for station-keeping, and the only way it would seem to have an advantage is if you have a specialised space-to-surface vehicle as part of the Moon base system. Even then, wouldn't a way station in LEO make more sense, protected from solar flares? -- Rabbit arithmetic - 1 plus 1 equals 10 Remove spam and invalid from address to reply. |

For pure grandeur of concept, that ring around the moon in the movie Starship Troopers is hard to beat- it makes no sense...but it looks really cool. I assume it's held in place by guy wires leading down to the surface with elevators going up and down them as the Moon is mined for materials. Pat |

There is some logic to having a station in low lunar orbit. If staffed it
would provide a manned lunar presence with out having to actually land. If unocuppied it t would give the astonauts a safe haven in case of emrgency. The problem is cost for the same amount of money one could develop a landing technology and create an abort to lunar surface option. One possibilty that would make sense is to have crew habitiats sent ahead of the crew. A habitat lands automatically on the lunar surface. A second, spare, habitiat stays in lunar orbit, becoming your space station. If disaster strikes the crew has the option to enter lunar orbit to access the remaining habitiat. Should the LEM not fire up for the return trip you could de-orbit the habitiat and use it for life support while a rescue is thought out. If the mission goes well the orbiting habitat is de-orbited and sent to the next landing site ahead of the next crew. A new "spare" is placed in lunar orbit prior to the crew's departure.

You can make your LM reusable, and leave it there between flights so you don't have to spend as much propellant hauling it around. -- JRF Reply-to address spam-proofed - to reply by E-mail, check "Organization" (I am not assimilated) and think one step ahead of IBM. |
