The FAA would be the agency that they interface with and that is why George Nield was in the audience (he is in Blackstar's photos)

Quote from: AJW on 12/07/2012 03:34 amRe: Landers, the goal is boots on the surface, and if a lander costs a few billion dollars and a separate launch, I have to ask just what is required for a propulsion system to get a single person in a suit down to the surface and back to LLO? Apollo 11's landing took an hour for descent, 2.5 hours walking the surface, and 3 hours back to the CM. Current suits can easily support this duration and LLO orbits are under 2 hours, so there are multiple opportunities for rendezvous. Additional supplies can be pre-dropped far more efficiently than what is required for a manned lander, an airbag landing that is also a habitat with a suit lock comes to mind. The LM was over 32,000 pounds, so the vast majority of the fuel was required for the lander, not the crew. It seems like we should consider tent camping before bringing the Winnebago along for the ride.We need to move past Apollo not less than it. The goal should not be boot on the ground. It needs to be a sustainable lower cost means for crew and cargo to the Lunar surface and crew return with some cargo.

If you get this to work, leveraging some cargo capability wouldn't be much added difficulty.

If they used propellant transfer, then nations with an indigenous launch capability could simply launch propellant on their own vehicles, regardless of size.
So, rather than the refueling approach, it would make more sense in that case to develop a low-boiloff TLI stage that could be launched as a payload by any of these vehicles.

Later phases, which are dependent on up-take of Phase-A will likely have far more capability.
I knew there were skeptics of this, but I think John Pike set a new standard in criticizing the plans: http://cosmiclog.nbcnews.com/_news/2012/12/06/15731458-golden-spike-space-venture-wants-to-fly-you-to-the-moon-for-14-billion?lite"But John Pike, a longtime expert on space policy who heads GlobalSecurity.org, said he was "deeply skeptical" about Golden Spike's business plan. "If you could do it this cheap, somebody would have already done it," he told me.Even if a lunar exploration program could be created for $8 billion, Pike said he didn't think the moonshot market would match Stern's expectations. "The implication is that they've got 20 countries that want to shoot people to the moon. I doubt it," he said.India and China might be interested — but after that, Pike said, "How many countries are going to be prepared to spend money to be the 12th to land on the moon? ... I think a lot of these rocket men are just taking too many happy pills."" Taking too many happy pills. Wow, he sure is blunt about what he thinks of their plans. I can't imagine Golden Spike appreciated that. As a backup plan for Golden Spike, does anyone know how much cheaper it would be to do what Excalibur Almaz is planning and simply send men around the moon or eventually to a modest LLO space station?
Too much dreaming not enough funding.Start with the money and no plan and I'll be more excited to be honest.

Going to the moon on medium rockets isn't a new idea.
If it's so cheap and easy why hasn't NASA been back since they had Saturn V?Going on a heavy lifter is the easy way that's why.
Extra rendezvous complicates the mission. More things can go wrong.
Is anybody going to have enough faith in this to put a big deposit down?

They might fail or they might succeed, let them try to create a new market and see if it succeeds. It takes courage to stand up and propose a new direction and be the first.

Quote from: Blackstar on 12/07/2012 02:46 amThat strikes me as a big problem. No sovereign nation wants to take money that they would spend either for science or technology development and send it out of the country. They want to spend it inside their own country, developing their own capabilities. If they want a Moon program and realize that they cannot afford their own Moon program, then they will spend the money on something else inside their own borders before they will give it to some American companies. Bigelow has essentially the same flaw in their business model.I understand what you're getting at, but don't forget that the idea is to give sovereigns the capability to send their own astronauts and science experiments to the Moon. That's not much different to, say, ESA science experiments hitching a ride on a NASA planetary probe/lander. Example: ChemCam and SAM on Curiosity are both joint US/France experiments.

I feel inclined to put this in the same category as the group that wants to send someone on a one way trip to Mars.Personally, I think they would help HSF by creating a private spacestation and prove low coast to orbit with a willing and expanding customer base.
Still think it's a crazy longshot, but not at all because of the technology or architecture. Doing an HLV any bigger than Falcon Heavy or FH+Raptor would only make this more expensive, not less.

These folks are not a group of eccentric bored billionaires. Going to Mars is several magnitudes more challenging than going to the Moon. We don’t need to invent new technology to go and do what we did almost a half century ago while still in the age of slide rules and vacuum tubes. Who knows, that private space station might still go up someday as well, just ask Robert Bigelow...A lot of people can safely say “I’ve never failed at anything” but did they ever try to do something that was never done before?
