    I have a very clear opinion on this topic: Please don't change anything in terms of content, that's what the many, many excellent mods are for, which are probably at least as valuable as the actual game. Technically, I would like to see a decisive improvement: Shorten the loading times. Other than that, I don't need any bad improvements, really.

    In my last video I said something wrong, here is the correction : the hydrogen boil off loss rate is 23g/h, 7.8kg/d, 201.5kg/a, 324 mL/h, 7.8L/d, 2841L/a

    Paper updated to version 0.1.3 (see initial post for link)

    The new HAB landing on Mars - video is online (see initial post) .

    I placed my current paper version (very very early) to my new MEGA account: See initial post. The whole thing should be a completely voluntary activity for the common good without any selfish interests. Everyone is invited to take part and of course we will mention everyone in the acknowledgements. Per Aspera Ad Astra

    @magnemoe I see it similarly. My first HAB also has four wheels and carries two harvesters, one for water and one for regolith. The landing site is at the colony, and it is abundantly filled with near-surface water ice (see NASA report). Deuteronilus Mensae. However, the first ERV is independent of water ice and brings its own liquid hydrogen for fuel production (based on Dr. Zubrin's book). This would even make it possible to land anywhere on Mars. Elon wants to move a million people there, so there will soon be a lot going on. Who knows if someone will need a ride back to Earth if they get lost. Oh, but we (or NASA) know exactly where there is a lot of near-surface water ice on Mars. @darthgently In any case, water is life. If there is enough will on the part of the people on earth, this will no longer be a problem, as the technical problems are likely to be solved. I am still looking for publications in this direction.

    Super interesting, thank you! Dr. Zubrin has also been presenting his “Mars Direct version 3” with the “Mini-Starship” for some time now. But I was already busy with his version 2 ;-)

    I will publish a video soon showing the current version 20A1 of the ERV on Mars. Here it comes: https://dai.ly/krTRUthEoYcjgVCjtAs

    Glad you are back !

    Currently I try to do the artificial gravity rotation with a HW-80 winch from the KAS mod. Problematic (but fascinating effects) since this is not a rigid connection.

    I also have it in my CKAN mod list. I use it carefully, had some bad experience with it in the past (I think with wheels, or landing legs, which leads to KSP crash), now it seems to be working nicely. I don't know if this mod gives me the fantastic procedural tanks, or RO Tanks, but rescaling the tanks is my daily work.

    I replaced the Heat Radiatiors of the ERV outside because I think it is a good idea to have this 450kW heat radiation in a good distance to the liquid hydrogen tank. Not neccessary due to KSP simulation but more realistic in my opinion. https://i.ibb.co/znd8BX2/ERV-New-Heat-Radiator-Place-small.jpg During Mars airobraking and Earth re-entry tests I again saw how important it is to have the center of gravity as near as possible to the craft roll axis. So I rearranged masses again, now having crucial systems like the water recycler, air pressure controller, MOXIE etc. doubled, which is important for redundance anyway.

    Artificial gravity 2 years after ERV1, the habitat ship HAB1 flies to Mars with 4 astronauts on board, accompanied by another ERV, the ERV2. During the flight, the TMI (Trans Mars Injection) stage is detached and connected to the habitation unit of the HAB by a long steel cable. The habitation unit and the TMI stage then orbit around each other and generate an artificial gravity that corresponds to that of Mars. Course corrections must still be possible with the RCS. HAB1 and ERV2 land at the colony landing site on Mars after a 9-month flight. Artificial gravity is generated on the return flight in the same way as on the outward flight to Mars. Once on Earth, the steel cable is cut, the habitation unit enters the Earth's atmosphere with its heat shield and then lands on parachutes in an Earth ocean.
