Need creative help

[Keith Henson]

This syngas from trash and solar energy project needs a catchy name.

L5 Society was the best name I ever came up with (desperate
situation). For this project, something with syngas in the name, Sunny
Syngas? Or maybe something pointing to Victorian gas production. Or
something about a step in the direction of carbon net zero. How does
AFP for alternate fuel production sound? Or MAGA for Make American Gas
Again ;-). The project spreads out over so much territory that it is
hard to sum up in a title or even a sentence.

I wonder if there are places that produce project names? I could try
on the extropian list and the power satellite group. Also, the Harker
list. I am not on Reddit, but maybe ask there?

And that was a great name! It's simple and sticks in the mind. Why they chose to change it to something generic and completely forgettable I have no idea.

I think O'Neill mentioned a 2 for one orbit, half a lunar month. But it does not make any difference as long as it is in free space.

At one point, I looked into lunar elevators. They work by going through L1 and hanging down into the Earth's gravity. As I recall, if you extended that part to around 190,000 km you were at the end of a Hohmann transfer orbit to GEO.

The big problem with any space colony proposal is to find something for the inhabitants to do. That takes materials. A space elevator off the moon would give them that.

hBest wishes,

Keith

Hi Kieran,

 

A 3:1 lunar resonant orbit (ie 9-day period) will have a perigee a couple of thousand km above GEO and an apogee a couple of thousand km below EM L1 altitude, but 180 degrees away (work it out).

 

We had a bit of a look at this when I was associated with Deep Space Industries, but nothing was ever written up / published.

 

Cheers,

 

Mark

Mark;

 

Interesting. I assume that you mean an orbit in a 3:2 orbital resonance with the Moon, just as Hilda is in a 3:2 orbital resonance with Jupiter?

 

Has anyone published anything on the orbital dynamics of such a quasi-Hilda in the Earth-Moon system? If so, I’d be interested to take a look.

What about habitats in an Earth-Moon Hilda orbit?

 

‘The Hilda Habitats’

 

Closer than L4 or L5. Resonant with the Moon. Close to GEO at Perigee, and to EM L1 altitude at apogee..

 

Can be fed by mass launched from Moon, or imported from NEAs.

 

Comments?

 

Mark

The reason was the merger with L-5 Society and National Space Institute (sometime referred to as No Space Intelligence).

This is one small example of the many, many things I saw with my own eyes.

 

The decision was to merge L5 with Von Braun's National Space Institute, to create NSS. I was the L5 rep to these discussions. If Gary Oleson still joins these discussions, he may also have relevant memories. The key person on the NSI side was Carol Rosin, whom I remember quite well from about four connections which immediately come to mind. (JUST now, I searched... she still has a big web presence; it says she is 82 years old now. Merger was intended to bring greater strength through greater unity, but opening to a larger constituency can sometimes dilute focus. O'Neill had a clear vision, and it is sad how it is not so visible to the world now as it was then.
