If Ascender will be real, then before they do the H1 version that supposedly could go orbital they would do lesser vehicles: https://jpaerospace.com/blog/?p=6869 Quote:

TransAtmospheric Ascender
The TransAtmospheric Ascender will be our first airship to reach space. The vehicle is 2100 feet long and will have a crew of three. It will have a peak altitude of 350,000 feet and a maximum velocity of Mach 5. Technically it is a hypersonic waverider. The TransAtmospheric Ascender is strictly a suborbital vehicle. It will fly from a Block 2 Dark Sky Station floating at 120,000 feet to space then return to the station. The airship will be driven by a single four chamber version of our symphony hybrid chemical/electric rocket engine.
The TransAtmospheric Ascender is still a few years away but as we get closer the design starts to firm up. Just thought you would like a look at where it stands.

I am very interested in knowing how their "symphony hybrid chemical/electric rocket engine" are to work.

My pea brain struggles.

Anyway I am imagining thinking backwards with it for Venus and Mars. Basing it in orbit, and letting it drop down on occasion into the atmosphere to extract chemicals.

For Mars, with only .38 g, this could be easier than for Earth or Venus. And Phobos and Deimos are in orbit for solid mass. A question is, if an Ascender could navigate though the mixing zone for the solar wind and the atmosphere of Mars, could it pick up Hydrogen and Helium? And of course Nitrogen and Carbon would be wanted.

Could this machine do Soaring? A lot of these things I only understand fragments of at this point.

Dynamic Soaring is being contemplated to be able to exceed the speed of the solar wind at the Heliopause: https://www.frontiersin.org/journals/sp … 17442/full

Dynamic soaring as a means to exceed the solar wind speed

It is a long shot for the upper Martian atmosphere, but a question might yield to an answer eventually.

I am not at all assured that an Ascender could land on Mars. But perhaps they could be based in orbit. And if no other source were available fuel might be extracted from the Mars atmosphere. At least CO2, which could be split into CO and O2, but maybe H2 as well. Carbon could also be a propellant for the Neumann Drive, and Oxygen might be propellant for some type of Mass Driver ships engine. But of course metals and Oxygen can likely come from Phobos and Deimos.

It would be very good to be able to refuel/refill ships in Mars orbits to access the asteroid belt and for trips inward in the solar system.

So, I am not sure I buy into the "Kardashev scale" notions. To me Venus says, no you are not going to learn to utilize all of the energy of Earth, to become Type I.

Instead, you are going to find that a world like Venus has a lot to offer, even if it is not your "Nursery World".

So, I think you would have a long period of being both Sub Type I and also a bit of Type II.

For Mars and Venus, solar power might be very attractive, at least in orbits, provided you had mass to build things with that is not deep in a gravity well. For Venus, Terrestrial Crossing Asteroids, may allow for access to Venus itself for materials. And of Course Mars, itself has .38 g and also Phobos and Deimos and then the asteroids as well.

I am just goofing around here:

Could a Space Station be made of 10 Starship Cones? (Cargo/Crew Sections)

I have put a red circle in so we can see how close we might be to a torus:

Because they are not used as fuel tanks, you could prefab them on the ground.

You may or may not spin the device for synthetic gravity. But at current Starship sizes you might only get to Lunar or Martian simulated gravity, I estimate.

That might be good as for tourism you might give the tourist a variety of alien gravity experiences. Plus when spun up, your sanitation is going to be more convenient.

You could use it for microgravity manufacturing where I expect it would be inhabited mostly by robots.

It might also move in the direction of a medium scale craft for transit, perhaps in a cycler of some kind or maybe even an expedition to Mars. (Not for landing though).

And this then is wanting to know what to do with the rest of the Starship, the Locomotive Section comprised mostly of tanks, and engines? Well, I have some notions as you might suspect.

1) Boosters for long range Starship missions.
2) Then perhaps reuse on the Moon.

So, of course the Starships do perhaps need two walls between the Nose Section and the Engine Sections. (But not necessarily).

But you can use the Locomotive Section as a "One-Time Tug" and then land it on the Moon.

When landed on the Moon, it is easier to tip over as it has been shortened by the removal of the Nose Section. And while it would not be prefabbed like the Nose Section may have been, the Moon can supply Insitu resources to upgrade the utility/habitability of these things.

So, the Locomotive Section may be able to boost a Starship on its way to another world, and then might land on the Moon, if sufficient propellants were available.

So, a Starship is supposed to be able to lift 100-200 tons to LEO, but if not to be re-landed, can lift more. Some of this would be eaten up by Prefabbing the Nose Section. But still you get to use all the parts for something that may be useful and you don't need flaps and motors or a heat shield. Of course you may need legs unless you have some sort of mechanism on the surface of the Moon to catch the Locomotive Section.

The Raptors might be removed and reused, I suppose.

So, then this is not quite like any of the Starship ideas so far, except for laying a Starship on its side on the Moon and upgrading it with Lunar Resources.

This would give Starship more reach, as you might use one or more Engine Sections to boost a Starship from LEO to another world.

If we then can have depots that can be moved around with electric rockets then we can arrange for propellants to be refilled near the Moon, as a further option.
