NASA Announces SLS/Orion Flight Slide

At this stage, Trump hasn't killed NASA and even said midly positite things about it. SLS hasn't been killed. When Mike Pence takes over in a few [days, weeks,months], he isnt likely to make big changes to NASA. Just how do you think Mike Pence 'takes over'? Can you seriously believe that a Republican Congress will impeach him or that a Republican Senate will remove him from office? Do you expect him to resign after the lesson of Bill Clinton? Are you thinking that the Cabinet will vote to find him unable to serve through mental defect? If you expect ANY of those you should cut back on your crack cocaine consumption. NASA staying under the radar is good in the sense that nothing drastic happens to it. On the other hand, there isn't going to be "to land a man on mars and bring him back safely before this decade is out" project. The problem with 'staying under the radar' is that you make yourself an irrelevant money sink and people will eventually notice that. -- "The reasonable man adapts himself to the world; the unreasonable man persists in trying to adapt the world to himself.

NASA has its marching orders, its budgets and projects all laid out, so it is pretty immune to watever happens to Trump in the next year. One year at a time. They're 'immune' until the end of September, then they better have a new budget. The one possible concern would be the ISS. The ISS relationship with Russia has survived the previous round of sanctions due to Ukraine, but with Trump, if he gets angry, he may decide to cut all US-Russia relationship with ISS, including USA providing electricity to russian segment. (not realizing that heither SpaceX nor Boeing are ready with their taxi service). What a silly notion. Question: in and Apollo 13 type of situation, could someone return in a cargo Dragon? Am thinking they send up a launch/re-entry suit with O2 tanks, and some foam mattress to cushion the landing? Or would such a trip absolutely not be surviveable? I wouldn't bet on it being survivable. Just throwing down some mattresses and letting everything bounce around inside the capsule strikes me as a good way to get back jelly. (Alternatively use a space suit). Same outcome. There are no restraint or cushion systems in the base Dragon that let you bring people back. -- "Insisting on perfect safety is for people who don't have the balls to live in the real world." -- Mary Shafer, NASA Dryden |

But if SpaceX sent up a Dragon with cargo, gets emptied, except for space suit and glorified mattress and bungee cords. Crewman gets in , straps him/herself in and goes down. And dies from being sliced to ribbons by bungee cords and jellied against the sides of the capsule. Since Dragon is able to return cargo, I have to assume the ride can't be all that difficult from a temperature or G force point of view. Cargo comes down in specialized containers that can be bolted into place. They don't just toss the **** in a pile in the middle of the capsule. Also, while crewed Dragon will have fancy ECLSS, control panels with blinking lights and buttons for crew control, how different will the actual capsule structure and retro rockets/parachutes be from the existing cargo one ? Seats. With restraint systems. And shock absorbers. You don't seem to understand that a capsule reentry can be a fairly violent trip as such things go. You're talking about peak deceleration of 3g-5g with random hard jolts in random directions. It's not a nice smooth trip like you seem to think it is. Or are current parachutes and landing rockets insufficiant for even 1 crewmember? That's not the problem. The problem is getting down to the point where you use that stuff. Again, this was an in Apollo 13 scenario where they have no choice but to rip up the manuals and do what is actually doable. Why do you ask questions and then argue with the answers you get? Either you know enough to already have an informed opinion (you don't) and so shouldn't be asking the questions or you don't know enough to have an informed opinion (you don't) and so shouldn't be arguing with the answers. If you have no choice you do it anyway and probably die. I really can't imagine a situation in which you'd have no choice. Why wouldn't you just use the 'life boats' that are already docked to the station? If you can't, why wouldn't you launch more of those? -- "Insisting on perfect safety is for people who don't have the balls to live in the real world." -- Mary Shafer, NASA Dryden |

The 'slowing from hypersonic speeds to terminal velocity' part. Seats. With restraint systems. And shock absorbers. You don't seem to understand that a capsule reentry can be a fairly violent trip as such things go. Which was the goal of my question, but you respond with silly arguments such as "jellied against the sides of the capsule". I'm sorry you find reality "silly", but there you go. How do you restrain your astronauts and their mattress? Bungee cords won't get it. Without FULL RESTRAINT people are going to get slammed around inside the capsule. You're talking about peak deceleration of 3g-5g with random hard jolts in random directions. It's not a nice smooth trip like you seem to think it is. Hard jolts? looking at space shuttle re-entry videos, the crew didn't seem any rougher than on a bus. The STS isn't a capsule, you ****wit. You didn't ask about shipping them a Shuttle to make an emergency reentry. You asked about stuffing them into a Dragon cargo capsule. The Shuttle is a ****ing plane with lift and control and great big wings and ****. Maximum g on a Shuttle reentry is like 2g. It FLIES down. A ballistic reentry like a capsule does, with some minimal lift, gives you 3g or more with jolts much higher. Note that the Shuttle still restrained occupants in seats, not just a mattress and some bungee cords. It isn't like there are flying pigs that get hit by the capsule during re-entry, is it ? It is a lot like that. You have an ablative heat shield that is vaporizing and shedding bits. You are flying very fast through air that is NOT of uniform density. The capsule is NOT flying on a great big ****ing wing, so you get a plasma sheath and a big shockwave going on around the capsule. All that will tend to buffet the **** out of it. Now stop being such a goddamned nitwit. -- "Ignorance is preferable to error, and he is less remote from the truth who believes nothing than he who believes what is wrong." -- Thomas Jefferson |
