Quote from: Coastal Ron on 02/18/2023 01:48 amI think LEO will be the logical place for transit points, where dedicated Earth-to-LEO transportation systems will transport people and cargo to LEO, offload it at the transit point, where it will then transfer to space-only transportation systems going beyond LEO. But that might not be of interest to Jeff Bezos either.I agree with your point. LEO is where the environment changes completely. Going from atmosphere to pure vacuum means that you can't really build a spacecraft that can operate efficiently in both environments without compromising a lot of things in the design. Yes, it can be and has been done (Apollo) but it is far, far more efficient to have a vehicle designed to opperate efficiently in either environment, not both.LEO is the perfect place for the space equivilant of an airport. You travel by ground transportation to the airport in a vehicle designed for the ground, where you board an aircraft, a vehicle designed to fly thru the air, to a destination where you board another ground transportation vehicle to take you to your final destination. You don't fly cars, trucks or trains in the air and you don't drive aircraft on the ground. What should be happening is getting into LEO in a vehicle dessigned to operate as efficiently as possible in the atmosphere where you transfer to a vehicle designed to operate as efficiently as possible in the vacuum of space. That's the most efficient and cost effective way to get to destination in space, like the moon or another planet.I don't even think Starship is the best way to get to Mars for this same reason. I like the design but it is optimized for the atmosphere, to do the skydiver move to bleed off reentry energy and control its orinetation in the air. A better approach would be for Starship to go to the "airport" in LEO, where an interplanetary spacecraft is already docked and waiting, dock to it, and just be along for the ride to Mars, where the ground crew would then re-board it to descend to the Martian surface. Starship would be the ascent and descent vehicle, but the interplanetary journey would be onboard a vehicle designed for that purpose. My opinion.Jeff seems to be floundering around, trying to figure out how to get a piece of the pie without even knowing yet what flavor the pie is. If he ever properly figures it out he would be a major player in HSF but until then I have come to view him as a major distraction. I didn't used to feel that way but his actions and non-actions in the recent past have changed my opinion. It makes me worry about the future of the Vulcan launch vehicle. As much as I like SpaceX, I do NOT want them to be a monopoly. We need ULA and, if he ever gets his act together, Blue Origin.For example, designing, building and operating the LEO "airport" would be a great way for BO to gain the necessary experience to properly plan and build an O'Neil cylinder, something that he originally said was his main goal.

The "airport" metaphor might be adequate for lunar transit, but it's less apt for interplanetary destinations, where inclination and RAAN at time of departure are a big deal.
I'm obviously speculating but I suspect Jeff's reasoning went something like this:1) Blue Origin should be the company that enables millions of people live and work in space.2) Millions of people can live and work in space only if we can build large structures in space.3) To build large structures in space, we need to get the building materials from the Moon.4) To get materials from the Moon, we need transportation systems that can land the necessary ISRU and manufacturing systems.5) To get those transportation systems, we're going to need a lander and a launcher to put the lander in space.6) To build a launcher, we need to start small, so let's build a New Shepard vehicle and use it as a cash cow.Point #5 was the critical error.
I thought his public statements (few as they've been) were that the moon was his goal. Elon wants to colonize Mars, but Bezos thinks it should be the moon.
Blue Origin was founded with a vision of millions of people living and working in space for the benefit of Earth. Blue Origin envisions a time when people can tap into the limitless resources of space and enable the movement of damaging industries into space to preserve Earth, humanity’s blue origin.
With all the investment Jeff Bezos has made in New Glenn, it is hard to see it as some sort of elaborate head-fake. Occam's razor leads us to believe that Jeff Bezos, at least for some period of time, was serious about New Glenn, and they certainly don't look like they are shutting down the program.
The airport metaphor is most appropriate for lunar surface destinations. But it would also be useful for interplanetary missions staged from an EML-2 station. The spacecraft could go to either the lunar surface or the interplanetary station at EML-2 which, delta-v wise, is literally halfway to anywhere else in the solar system.

Bezos thinks the Moon is the means to the end of getting millions of people to live and work in orbit, which is his ultimate goal. As robotbeat said, Bezos is an O'Neillian. I think he's right. I think this is much more likely than building a vibrant civilization on Mars. But if SpaceX is wrong, they can eat Blue's lunar lunch any time they want to, and Blue can't defend itself.

Blue Moon appeared to be that, but it was thrown away in lieu of a multi-company bid. I wonder what they'll propose this time.

But... weren't they talking about space/LEO manufacturing?Not really, there is no business case. If you listen to the entire interview (Eric Berger is the space journalist from arstecnica), they go one to talk about how no one has a closed business case for a leo station yet. Its always been that "magic thing you manufacture in space" since the 70s. After 50 years, no one has any idea what that is though.Then Varda Space and others are dead too...

Yes, I agree that the design is relevant or could be redesigned to be relevant for the '20s. But even if relevant, Blue doesn't appear to be ambitious enough on launch rate to impact SpaceX's market position appreciably.
Bringing it back to LEO/Lunar/Mars - I'd listen to what Musk has to say. SpaceX showed zero interest in orbital stations, and a very limited one in Lunar presence - even though they are positioned to dominate both. There's a reason for that.
The problem with NG was not the concept itself - it was basically a "me too" to the F9's "I'm first" design.
