So what's Endeavor doing now? I know it'll be docking with the ISS in a few days, but what's it up to in the meantime? This is it's last time in space, I home they're doing some cool shit with it while they got it...

also, general space vehicle appreciation thread

I love space vehicles.

They are the best.

I wrote this for my astronomy class and got extra credit

"If you had a race car. Lets just say. It was a space race car. And the space race car was racing the space shuttle into space. How long of a ramp would the space race car have to jump in order to beat the space shuttle into space? Would it make a difference if the space race car had to jump over a train in the process? "

So, what are we gonna use after the Shuttle Era ends?
I know we're gonna use Russia's Soyuz for a while, but we're not just gonna do that forever...

I just want to point out you can tell that that image is not canon because the phasers are blue. That image is a complete insult to all of star trek. Everybody knows that the phase buffers dont operate at a frequency that produces blue light. What do they think we are stupid.

The whole Orion thing doesn't make any sense to me.

What possible advantage could there be of propelling yourself with nuclear bombs over propelling yourself with a fission fragment rocket?

I can't imagine that the bombs option is in any way more efficient or safer.

I think Orion was more meant to demonstrate that you could use nukes to do other stuff, besides blowing the ever loving shit out of the Kremlin. Interesting though, had to google fission fragment rockets..
also found VASMR

Okay, I've looked at it, and I think that Orion was a VERY early nuclear rocket idea, hatched when bombs were pretty much the only practical thing anyone had done with nuclear technology. Even then, they were a second-generation idea, when the initial idea of detonating nuclear bombs within a combustion chamber was rejected as impractical.

After that they developed nuclear jets, ramjets, and thermal rockets (solid, liquid, and gas core) that all (potentially) prevent any release of nuclear material during atmospheric or orbital flights.

Then there are nuclear-salt-water rockets, which are ideal for high-thrust applications where environmental damage isn't a concern (planetfall, emergency maneuver), and fission fragment rockets, which don't provide a lot of thrust, but are ideal for propellant efficiency on long trips (including interstellar voyages).

Orion has been obsolete for a long time.

No? What are we going to use? Unicorn-drawn carriages?

Bush killed off STS without anything resembling a viable replacement on the horizon, and congress has been diverting most of NASA's funding into pointless pork projects like Ares.

Excuse me but
>environmental damage isn't a concern during planetfall
wat

Also Orion wasn't an attempt to make nukes look better.
The idea for the niclear pulse drive came, when a stopgap metallic plate placed on top of a borehole for an underground nuclear test went flying at incredible speed when the seals situated deeper had failed.

The speed of the stopgap was never accurately measured, in a high-speed camera the stopgap just was there in one fram and then wasn't there in the other, calculations from which turned up some incredible lower bound for the speed it must have attained.

While the concept for the drive system is decades old, it has evolved over time, with more recent designs employing antimatter-catalyzed fusion and laser fusion. Even the fission-type systems have advanced, with materials resulting in extremely low amounts of fallout for even the heaviest designs.

And of course, the Orion drive concept has branched off into other more and less exotic drive systems, like the Uranium-sail and the passive laser-pulse drive.
