The lack of parachutes here is finally actually a benefit, as you don't have to worry nearly as much about anti air shredding your special forces team while they're slowly floating through the air. Instead of having to send out a helicopter or plane full of troops, you have soldiers stationed in orbit who are "on call", capable of rapidly landing fully combat-ready for precision strikes. The third option is a military application, and this one is the most interesting to me. This one makes even less sense, because if there's any purpose at all to deploying the escape pod (i.e there's a planet you can escape to, rather than just ditching the ship and then floating in the void until you asphyxiate) there should be an orbital station as well, which will be much easier to dock with than trying an emergency landing down a gravity well. The classic escape pod is another option, similar to the above but launched from a spaceship, not an orbital station. Medical evacuations come to mind, but I'm not sure how many situations there are where subjecting yourself to double or triple the g load of a normal descent is worth getting back to earth slightly faster. If your goal is just to get away from the space station because something has gone so wrong on board that you don't have time to slowly drift away, you just need one good push to clear the immediate danger. However, it uses parachutes after atmospheric braking which disqualifies it in my view.ĭo any of you think there's a real practical use for a reentry vehicle that descends from orbit purely via atmospheric reentry and retro rockets?Ĭivilian applications seem limited to me, because the decreased time to landing doesn't seem worth the extra g forces and cost this would entail. We're already surprisingly close to the basic principle, with the Soyuz having a backup option for a "ballistic reentry" where it enters the atmosphere on a very steep trajectory rather than skimming. I'm curious about the mechanics and feasibility of these vehicles, especially in the near term (within the next 100 years) when humanity is still growing into our solar system. I could have sworn Isaac discussed this in detail somewhere, but all I could find was a brief mention of it in "planetary invasions" when he's talking about starship troopers. Your religion or politics suck, mine rocks The Election Calling people idiots, especially "That's not how thermodynamics works, moron", even when true :) Short form, keep it courteous, keep adult."I love/hate this Scifi or fantasy book/film, how about you? Other science videos, articles, podcasts, etc (in moderation) Science talk, geek talk, etc. My videos, obviously, or the topics they cover."How would you govern a Dyson Swarm?") but that's not generally how it goes on the internet, I'd rather have none than that. I entirely encourage polite and civil discussion of these where it is proper (e.g. It is not banned, yet, but tread lightly. I've noticed that as soon as groups start having those topics as regular features they become echo chambers.
