  1. The Economics of Platinum mining

    Significantly lower. No need for parachutes. Looks like the REEs are where it's going to have to be instead of the platinoids, TBH. Although, again, I wouldn't be surprised if they aren't as much of a bottleneck as people like to claim. There's always the option of aggressively negotiating their ships into cinders before they leave Earth's SoI. All you need is a friendly government willing to play fast and loose with unilaterally imposed space law.
  2. Well, everything beats drop bears... In theory, but in practice someone needs to expect the hardware to be useful and put up the initial costs. There's quite a bit of subjectivity involved when undertaking massive, decades-long projects.
  3. NASA again looking at Nuclear Rockets

    Not sure if at all doable. It's about neutron physics, not chemistry; the neutron moderation properties of the rapidly flowing propellant require extreme care in operating even a single-propellant design.
  4. I dunno, did they even check that at Kama-1 before they started dumping the waste from the UDMH plant into that void?
  5. Fusion, no, but I've seen this seriously discussed as an alternative to fission reactor powerplant - just harvest the heat. The Taiga nukes designed specifically for the program were 98% fusion despite modest yeild. Yes, fallout reduction was a key goal. The preceding Telkem blasts were using tiny, 240 t nukes. That said, they were designed primarily for seismic sounding, linear excavation, geological engineering, and firefighting (see below). What you appear to have missed is that about four-fifths of Soviet blasts were operational, rather than R&D.

    I can agree with STD (they seem to be tryhards for the ‘dark and gritty’ style of nu-BFG) and JJ-Trek, but TLJ? Where one charecter is directly rebuked for trading a bunch of subcapital craft, while the other has his chance at sacrifice and potentially saving the Resistance (and have a meaningful charecter arc) stolen from him? We didn’t watch the same movie.
  7. And this brings us to a potential source of significant damage. Musk simply being a trucker service is not how the public perceives it anymore - especially since he needed a third party to build the propellant factory. Instead, SpaceX is perceived as an independent space agency that has long outmatched NASA. This sets Musk up for a massive failure to stand up to the public's extremely lofty expectations that is going to knock the wind out of the hype train. This runs back to why I hate the "[soft] sci-fi raises support for actual science and spaceflight" argument - because it is patently untrue. The crowd that's in deep love with the X-Wing is at best a fairweather friend to the Soyuz - if not an outright problem, because they're conditioned into a wholly different mindset with a bunch of false assumptions. Should they run into reality and its own, entirely different set of challenges, which is more likely: a complete reconsideration of their mental image of the majority of the Universe, or a retreat back into fantasy with disregard or outright hostility to actual incremental development? What happens should Musk backpedal further, or when he nearly inevitably fails to deliver (seeing as the hype has long outrun any plausible outcomes)? There is a finite amount of flying fraks the public has to give, and one should use them more sparingly. Considering Mars colonization will still be quite dependent on political will and thus hype, someone in the post-Musk era might find that quite a few bridges have been irreversibly burnt.

    Uhm... is it? https://youtu.be/rCB8DUGpYQQ?t=239

    Hey! At least the Dambusters had a range greater than zero! This one appears to have been hoist by its own petard... which begs the question of whether they even expect these things to not be kamikazes. Even Rogue One knows what a Y-Wing is.

    And don't forget our new best friend, MG-100 StarFortress SF-17... Oh, wait, it's exploded because someone dropped a spanner into the munitions bay... oh, and it's taken out another two bombers!

    Oh, did you seriously mean THAT Wattpad?

  13. Then we’re back to a) Buck Rogers the Government Employee, or b) not going to Mars. If we drop (b) for the purposes of this thread, the best we can grab onto is that the government does things that are not to its benefit. That’s why it exists in a capitalist free market, to do things that cannot be expected to be done by private companies in an acceptable manner (“Well, why don’t you build your own road?”), usually described in theory as public goods et cetera. To justify Mars settlement, one has to show that there’s a societal greater good even if the endeavour is not financially in the black. Sadly, I can only see this working out for a flag-and-footprints mission where the public good being delivered is ‘inspiration’.

    Partly that - but partly because individual MIRVs have no or at most attitude thrusters (usually they're just spin-stabilized); so the bus performs a number of lateral burns as it disperses each payload.
