    Great topic and guest! There has been some talk of Valles Marineris as a landing/colonization site because it is roughly equatorial, runs roughly east/west so gets more sunshine, has more shielding from cosmic radiation, is warmer with thicker atmosphere because of up to 7 km depth, and because of being lower is thought to have more subsurface water despite being equatorial.

They’ll be surprised at exactly how hard it was for us to get to Mars and how much time we took just to select places to initially land and explore.

    I wonder if Valles Marineris, or one of the side canyons, would be a good place to start a potential human habitat. It is a lower elevation, so more/ denser atmosphere. And there would be easier access to layers of rock in the side cliffs, and possible water. Also, where the valley narrows, one can imagine a clear roof installed and possible enclosing the ends to form an earth like atmosphere and habitat.

    Another real world example of small group of people, physically isolated for months with inconsistent communication back to the world are the winter overs in the various bases on Antarctica. Look at the winter overs at Pole. They are isolated physically from the world with no flights in or out. With a hostile environment outside where exposed skin can be frost bitten in minutes. And communication only for a few hours a day. If something happens when there is no satellite communication, they have to either solve it or be able to hold on for hours before they can communicate back north. Granted, once communication is back up the delay is only about a second (transmission to geosynchronous orbit and back). But that communication window is only a couple hours long. Not an exact parallel to moon or Mars, but I would expect there can be some lessons learned there.

    I heard Fraser mention Starship once but have yet to hear Rick refer to anything SpaceX. I can understand there might be some reticence to overtly plan on Starship since it's unproven so far but I hope that, as it demonstrates success, its potential will be more openly acknowledged. Rick mentioned the disappointment of drilling a two-meter hole and coming up dry but, by being able to land 100 Earth-tons of payload, Starship could include a commercial self-propelled drilling rig that could sink a large-diameter hole to profound depths if need be. A larger crew, years of food supply, habitat-building robots, and all sorts of equipment could be sent, and not just a single ship but a small fleet with large rovers with 1,000 km range, small thorium reactors, Sabatier methane plants, and you name it.

Starship has already been selected by NASA as the first human landing system (HLS) for the Artemis program and mission planners have been encouraged within NASA to "think bigger" since Starship should obviate the need to miniaturize everything due to its enormous payload capacity. We may disagree on the desirability of colonizing Mars but you cannot deny that, with a number of Starships ready to launch and refuel in orbit, it's best to launch several at a time in the optimum Mars launch window that occurs every 26 months. Naturally, this all depends on the success SpaceX has in developing Starship. If it ends in failure then yes, we are limited to other means and slower progress, so >20 years would be reasonable.
      My main point is that old ways of planning still dominate at NASA and it will take time for the potential of Starship to change that.

It is a massive over-the-top rocket that is unlikely to work in its current form. Major refueling in orbit is unproven. Starship is too big to be in demand for the current satellite market. Human rating will be difficult. The only reason it was chosen for HLS is Musk low-balled the bid. Any talk of launching multiple Starships with huge payload and human cargos is far over the horizon.

      @@jamese9283 Unwise to EXPECT for sure until it can orbit and deorbit successfully and until refueling in LEO is perfected. I disagree with the "too big" view as it is already in demand for Starlink satellite deployment and, at a projected cost per kg to LEO of just $10, think of the benefits to rideshare launch customers. SpaceX has already done this with a number of Falcon 9 launches where the cost is over 200 times higher assuming a planned booster and fairings recovery. Also, "Musk" (more likely Gwynne Shotwell) didn't offer a deceptively or unrealistically low bid. Look at the cost difference between the Crew Dragon and the Boeing Starliner. SpaceX is mission-driven, leaner, more efficient. Also, SpaceX is not charging for Starship development since it was already in development for the Mars colonization mission.

    Great content. I did observe that all of Rick's scenario planning seemed to presuppose that NASA will in complete control of the mission architecture and that none of the mission architectures he described seemed to include Starship. I'm pretty sure there is no way NASA can fund their own transportation for the Mars program. Hopefully, they are just being politically astute because there is no formal agreement for commercial involvment rather than being naive about their role.

    awesome talk. But I can't escape the feeling that building large space structures like O Neil cylinders "close" to earth would be safer and possibly faster. As a way of exploration and scientific discovery, planets and especially mars will always draw humans to advance our knowledge.

    • @wissevries3514
      @wissevries3514 Рік тому +4

      While O niel cylinders sound easier in theory. There are several problems that are not immediatly obvious, you need to assemble a massive amount of material in space to build it at a scale where it could be self-sustaining. This is going to be very expensive. There are als micro meteorites, radation, orbital decay and lost of complicated astroid harvesting and in space construction technology that needs to be developed. Personally I think both options are equally hard with there own pros and Cons.

    Mars habitats could have passive air locks. Picture a J-shaped tunnel filled with liquid. The low end of the "J" is a pool inside the pressurized habitat, and the high end is a pool on the surface. You put on your space suit, go down a ladder or ramp to the bottom of the "J", then climb up to the high side, and your on the surface.
    But surely the liquid would freeze or boil off, right? Not necessarily. I found an article on line where researches showed that very salty brine could stay liquid on the martian surface for years. But I think some sort of alcohol would be better since it would cleans any perchlorates off the suits of returning colonists.
    Think of the mass savings if they don't have to bring a lot of massive air lock doors from Earth.

      Sounds like a Delta P disaster waiting to happen. Underwater welding and maintenance is problematic enough on earth on things like oil rigs divers die all the time from that one hidden killer I'd imagine being an underwater welder in Mars is not gonna make it easier. Your method is similar to how welders work on these oil pipelines already and people have died when protocol isn't followed perfect or things fail. I remember one story where the divers were sucked into a pipe because of the timing involved with the plugs in the pipe which are meant to maintain the air pocket for the divers and the mishap basically made that air pocket catastrophically fail and they got sucked down the pipe.

    An EVA on the space station - and (not) on Mars:
    The ground support: "Grab your motorized tool (power drill), configure it for 5 turns left, torque setting 2". (These would have been multiple calls, I simplified it).
    45 minutes later: (when on mars)
    Astronaut to Earth ground support:
    "It doesn't work".
    45 minutes later:
    "Oh, try it with torque setting 3".
    The astronaut on Mars would have this up to 45 minutes delay from his question to the answer, the Earth ground support would also have this same 45 minutes delay between his answers to the astronaut and the response from the astronaut.
    ;-)
    Yes, you both are right of course, they need to be able to do that on their own on Mars. Maybe test this on the Moon and on the station as long as the station is still up there.

      That's my thoughts too. Send like 5 fully loaded Starships there with plenty of robots to get things started so that when the first humans arrive, they can get right down to doing the science and other things robots can't or shouldn't do. Having to go there, get all that stuff ready upon arrival, doesn't make sense given we already have capable robots.

      ​@@RickL_was_here You have this idea of our current robotics to be way more advanced than it is. Staged videos (Boston Dynamics) aside, our current best robots are stationary, working in factories and assembling stuff. And they still need humans in the mix for when random things go wrong outside of their control. Mars is an extreme environment, with more radiation, dust, and less heat, water, energy sources, that this problem is multiplied many fold. You'll need humans at least in orbit around Mars who can operate those robots without the time lag, and be there to troubleshoot before real problems arise. But, if humans are already in Mars orbit, may as well land them to help with those activities.
