Re: Interworld Para Terraforming
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.
