    SpaceX Discussion Thread

    That's what I thought too, but I wasn't sure, thanks

    OH, and I don't know if that would be reusable mode, or expendable mode. I think it would be towards expendable, but someone more knowledgeable will have to make the calculations

    So I decided to make a solar system...

    That looks like you recreated the outer solar system

    SpaceX Discussion Thread

    Technically yeah. Working off the top of my head, I think it can be several times larger than New Horizons. Let me check, and I'll edit this.... According to their official page: https://www.spacex.com/falcon-heavy yes, they can. It says 3500 kg (7720 lb) to Pluto, and New Horizons was 478 kg (1054 lb), so FH could technically launch something over 7x heavier to Pluto.

    Mars 'impossible" to terraform

    Yeah, but still, liquid water, thicker atmosphere, cool/temperate temperatures, sounds fairly habitable to me, at least in the base sense. If Mars was like that today, we'd probably be tripping over ourselves to settle it.

    Mars 'impossible" to terraform

    Mars is not just "That rock". Aside from the Moon, it'd be an excellent stepping stone out to the rest of the solar system. A lot of people here are advocates for space habitats, but I think the public will likely react better to boots on the ground instead. At least at first. (And publicity may be one important factor in the early days of space colonization. Look at how interconnected we are today, and how public perception can spread). It also has a load of raw resources and plenty of water ice, perfect for developing another industrial civilization without relying on resources from Earth after a while. There's also plenty of research opportunities. Right now, we're limited by how much we can send to Mars to study it. If we have people and manufacturing capabilities on Mars, we could build what we need and want on site, without worrying about time, or distance. We also wouldn't be limited by size, so we could get some large-scale scientific operations going. We haven't been able to get a deep in-depth look under the surface yet for example. Plenty of people want to live on Mars. The Mars-One project (Which, for the moment, let's ignore the feasibility), had over 200,000 people signing up. That's pretty significant regardless of your views on the project itself. And SpaceX's BFR is supposed to be economical enough to allow anyone willing to save up to go. To the point it'll cost the same of a moderately sized house, or luxury car (And since it'd be to colonize, you wouldn't need anything on Earth anymore, so you can sell it). That would open Mars up to millions of people. Not all will go, but enough would want to. It may not actually reach that low of a price, but it should be low enough many will have the option open to them. As for radiation, you could create bricks out of the Martian regolith to protect you from it. And put your water in the walls between you and the outer hull for even more protection. After a while, you could even add a magnetic field generator powered by solar panels to provide even more protection on top of that. And because Mars was much more habitable in the past, we may be able to bring that back eventually. Mars is the perfect place to make more Earthlike (Venus would probably be better due to its size, but it's a lot harder to reduce an atmosphere and lower the temperature), so colonizing would give us the incentive to terraform it. Is there a profit to be made? Maybe, but probably not a permanent one. Is it worth it when we have all these other issues on Earth? A lot would say no, but the amount actually being spent would be smaller than what's spent already on dealing with those issues. So there's nothing saying we can't get both at once, or that we have to prioritize it.

    Mars 'impossible" to terraform

    Whose talking about all of them? At most, I'm guessing it'll probably be Mars and Venus. Maybe the Moon if we're feeling cheeky. This is (simply, but not really simply) the more extreme side of geoengineering. If nature can do it, why can't we figure it out? And what's insane about it? The time it'll take? The resources required? Sure, that's all pretty wild, but not a reason for why we shouldn't if we could. Because if we could terraform Mars, we probably will do it, or try it somewhere else. Also, regarding your comment on taking a million years to terraform, and how an asteroid would hit before then; one proposed part of terraforming is redirecting asteroids to hit the intended planet to increase its water volume (Among other things). Redirecting a single asteroid away from Earth at that point would be laughable. Heck, we're close to being able to do it now. We would probably just send it to Mars instead. And a few thousand years might be on the low side, but who knows what our industrial capabilities will be after a few hundred years of working in space. I'm not talking about "advanced technology is magic" either. If we span the solar system, have massive mining bases on most major bodies, and various colonies/habitats all over the solar system; nothing short of a nearby supernova or gamma-ray burst could stop us.

    Mars 'impossible" to terraform

    I think terraforming would still be on the table for many. We already see today, how many people would rather live on Earth than in space. And in the future that may morph into people preferring to live on planets rather than habitats long-term. It might start out as small; but in an industrialized solar system with billions upon billions of people or more, that could easily mean millions to hundreds of millions of people (At least), willing to dedicate resources to create Earth analogs in favor of orbital habitats. But not just willing. They would probably be able to allocate the resources and everything for it too.
  9. What would I possibly do with 10,000 Moons?? I suppose I could terraform each one but that would take forever. I wonder if Isaac Arthur would have some ideas if he had the same situation xD

    All the boom, with none of the radiation! And bonus ice and Co2 as well, it's a win-win!

    Mars 'impossible" to terraform

    Even if Mars doesn't have enough CO2, or other substances, the Asteroid belt and/or Venus does. The project would take several thousand years at least, what's another couple hundred or less to get the resources to Mars? I don't think it's too much of a stretch to say the only way Mars can't be Terraformed is if we decide not to altogether.

    An underground lake was found on Mars

    And life may find a way But even if it doesn't have life, it'd be great to study as an edge case for the limits of water-based biology.
  13. Scientists have announced an underground "lake" of liquid water 20 km across, and 1.5 km below the surface. It's not clear if life could arise, as the water is very cold, briny, and full of salts made of things like sodium and calcium. It was found by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) instrument on the Mars Express spacecraft. https://www.bbc.com/news/science-environment-44952710 http://science.sciencemag.org/content/early/2018/07/24/science.aau1829 This is really exciting regardless

    New analysis of the 55 Cancri system

    So if I read that right, since its discovery, its gotten smaller? What could that mean for the planet?
  15. So I was watching a KSP video about an Eve lander (Matt Lowne), and he mentioned a really interesting project called AREE. Or Automaton Rover for Extreme Environments. And I'm really wondering how I wasn't able to find any thread (Unless it's buried deeply) about this project. Because instead of using electronics for calculations, it would use a mechanical computer. The rover design would be based around WW1 tanks, and it would transmit data using Morse code. From the first article; https://www.nasa.gov/feature/jpl/a-clockwork-rover-for-venus https://www.nasa.gov/directorates/spacetech/niac/2017_Phase_I_Phase_II/Automaton_Rover_Extreme_Environments It seems like it wouldn't be fully mechanical, but considering what they're looking at, it's still incredible. It'd be awesome to see an almost 'Steampunk'-esqe lander on Venus someday. Additionally, I wonder what it would entail; using mechanical technology for future space missions. Either as a reliable backup for electronics in case something breaks down, to the more extreme such as an alternative way for sustainable life support systems to make future colonists less dependent on technology. Or to give them ample breathing room as opposed to limited life support like meal bags and CO2 filters.
