Yeah, we're up to 2 busted nuclear plants in the whole world.

Chernobyl, Fukishima, Windscale, Three Mile Island, Fermi... that's 5sites just off the top of my head. We've only had two major accidents - but enough serious incidents and close misses that only a fool would talk about how having only two "busted"plants is proof of anything.

So, when the Wright Brothers were building their plane you were standing their telling them it couldn't be done eh?

Nope. Unpowered flight already existed by the time the Wright brothers headed to Kitty Hawk, and powered flight was right on the edge of possibility. The drives you propose, aren't. The problem is, you don't grasp that fundamental difference and thus assume that people who aren't as egregiously ignorant as you are the ones in the wrong.
 

Just because there isn't off the shelf technology at the moment doesn't mean we shouldn't strive for longer term solutions to interplanetary travel.

True. But those solutions must fall within the bounds of physics and chemistry - and nuclear reactors and ion engines, for the reasons I outlined, don't. Absent new physics, they never will.
 

Regardless of the propulsion system, having electrical power, lots of it, is the difference between coasting from A to B in a tin can vs something that could actually be called a Ship.

Only to someone who doesn't grasp physics in general as well as the mathematics behind orbital mechanics. Absent new physics, all vehicles in space are going to spend far more time coasting than under power.

It's time to stop jetting around the solar system on chemical rockets. Designers and funding should be directed towards lofting and running multi-megawatt reactors. They would be used to power multiple ION engines

Yes... let's develop heavy power sources in order to power weak propulsion systems - what a great idea! Multiple ones aren't much better, you still need to power them, and you have to multiply a small number (thrust per engine) by dozens (or more) to get a usefully large number (thrust) for any significant spacecraft. (Which will still be far short, by orders of magnitude, for a useful size for a manned mission.)

Their extraordinary ISP is very attractive from an academic point of view and when considered in isolation... but real world vehicles aren't academic and the engines are but one part of the whole vehicle. When you start to design an actual vehicle and an actual mission, their extraordinarily low thrust-to-weight ratio precludes them from being useful except in a few very specific circumstances.

What Russia did to Georgia in 2008 is a continuation of what Georgia did to itself in the early nineties

i stopped reading there

russia has no right to invade a sovereign country. do you understand? of course they have a "reason." do you have a functioning brain? can you see through their bullshit?

russia meddled in an *internal* georgian dispute that occurred within the internationally recognized borders of georgia. then it divided the country into a "new" bullshit country abkhazia

is it ok if the usa invades the mexican district of sonora and announces that it is a new country? why can the usa do this? uhhh... drug smuggling. yeah, that's our reason. perfectly good reason, totally understandable, right moron?

what was russia's reaons for invading georgia? guess what: it has no fucking right to invade and divide a sovereign country on those hopped reasons. do you understand what sovereignty is?

can the american fbi go into canada and arrest people? no? why not. can the us army occupy ontario? why not? because canada is a sovereign country, you dumb fuck

why do you think it's perfectly normal and ok for russia to invade and divide it's smaller neighbors? it's not normal. it's not acceptable

no country, anywhere in the world, does what russia did to georgia and ukraine without consequences. not south africa and mozambique. not china and vietnam. not brazil and uruguay. countries do not invade other sovereign countries and that's just normal and fine. do you understand?

if you do, continue speaking on this topic. but if you continue to assert russia invading and dividing georgia and ukraine is "reasonable" then you do not understand what the fuck sovereignty means and are therefore announcing yourself as a complete moron or a propagandized idiot on this topic and you should shut up

what's actually important is the fucking borders of a fucking sovereign nation, and that modern states respect that

you didn't notice the imperial bullshit russia did on georgia in 2008?

russia is doing imperialism 1850 style. it needs to be, and will be, punished for being a stinking pile of destabilizing shit because of insecure nationalism. oh glorious russia has fallen from historical highs, boo hoo. and it will fall further now

As an engineer I want to reuse and expand and not throw anything away.

If you were truly an engineer (a real one, not just someone with an overinflated title), you'd know that things age and wear out.
 

NASA can't build tin cans that can survive in space for a hundred years? There are planes from WW2 that are still flying and those rattle.

A real engineer grasps the impact of parts count and complexity. Not only is the ISS not just a "tin can", those planes are orders of magnitude simpler than the ISS.
 
Not to mention that those planes take hundreds of man hours a year to maintain in flyable condition - and man hours in space cost tens of thousands per.
 

Things get at least a hundred times cheaper when they don't have to survive the stresses of liftoff.

Sure, as any engineer knows, you can easily manufacture things given enough infrastructure. Since you're an "engineer", you should be able to estimate the cost of developing a (currently non existent) weightless capable factory complex, and the costs of placing hundreds to thousands of tons on orbit, and the ongoing costs of logistics, support, and maintenance needed to produce those "hundreds of times cheaper" parts. You'll also be able to understand that a space craft is made of hundreds of different kinds of materials, only a few of which are amenable to recycling.

yes, i am familiar with this faulty line of reasoning

the simple response to your logical fallacy is: because grey areas exist doesn't mean black and white don't exist

it might not be possible to draw a hard line on behavior. but there is behavior which is clearly not in a grey area and clearly calls for a judgment against you

this pilot had clear signs of being untrustworthy to fly commercially. it's not fuzzy and unsure

if you don't believe me, wait until a few years when the first verdicts come down in this case. a judge/ jury will decide on his employer/ the govt fucking up. the facts as they appear now show a clear problem that should have precluded him from piloting any plane with people on board
