thing is capability is an x factor. i dont think anyone here or at spacex for that matter knows what this design is actually capable of at this point. that must be determined in testing.

^ we know what causes that now. don't midair refuel without protection.

i watched dune2, then i spent the last 10 hours talking about it on any forum i go to that has a dune thread.

Metalic hydrogen diamond engine?(or other form of carbon.)
Nuke replied to Arugela's topic in Science & Spaceflight
diamond scarcity is mostly enforced by a small number of diamond cartels who fix the prices. diamonds are not in fact rare. granted you probably cant source enough to use as rocket fuel. -
posting pics in forums is lostech to me, but if i were to post pics id have to post scaled composites proteus and boomerang.

The Upcoming Movies (and Movie Trailers) MegaThread!
Nuke replied to StrandedonEarth's topic in The Lounge
finally saw dune2. went way off book there, but in a good way. gods below the worm scenes were awesome. -
the software i run today is either old software, or open source software. was not too happy when autodesk bought and killed eagle, so i use kcad now. i still use a 10 year old version of 3ds max and not looking to upgrade any time soon. if i wasnt making do with gimp id be looking into setting up a vm so i can run photoshop 7. i have no desire to buy into cloud-based software.

things were better when computers were just computers. not a data mining apparatus used by someone who didn't pay for it. tech especially in the last 5 years feels like its all been phoned in. software is a barren husk when they sell it to you. the goalposts are constantly being moved, and reliability has gone to hell. cloud services and accounts shoved down our throats even though nobody really wants/needs them. i bought hardware i want to run software on it, not something out of my control. i dont like the internet being a requisite for basic functions. i want to go back to physical software bought anonymously at a store for cash.

How Would Humanity Develop If Immortality Was A Thing?
Nuke replied to Spacescifi's topic in Science & Spaceflight
also see zardoz. immortality sucks. -
i honestly dont think one of these startups is going to beat iter to the punch. i used to think polywells were going somewhere until they weren't (they seem to have abandoned experimental approach and are now working with computer models, quietly, and not putting out any papers). seems while fusion startups try to find funding, iter is dropping in coils, some of the biggest superconducting coils humanity has ever seen. none of these are drives though. i figure the "asymmetrically leaky reactor" type drives will be a ways out. but those will be able to run steady state and provide power, which is what you will need for manned missions in the outer solar system and beyond. or just keep the reactor closed and use plasma thrusters (but you could do that with fission and nothing new need be developed). the technically fusion drives will come first, since you just need to funnel fusion products down the tail pipe.

forgot about that one. lol.

How Would Humanity Develop If Immortality Was A Thing?
Nuke replied to Spacescifi's topic in Science & Spaceflight
yea, you dont want to get blowed up by a vorlon dreadnought. its not pretty. i personally think it would be a total disaster. there's even a thrash metal rock opera about that. -
my guesstimate is before fusion power. and sicne the drive wont be break even, idk what kind of power requirements we are looking at. there are some pretty low tech fusion methods. one in the uk i always forget the name of, they literally shoot at fuel cubes with a big gas gun. their research is mostly optimizing the kinetic targets. something like that with a proton-boron fuel. if you can make it go brrrrrrrrrrrrrrrrrrrrrrrt into a magnetic nozzle, you might have something and something that wouldn't require a lot of power to operate. pretty much just the superconducting magnets in the nozzel, and a few actuators/valves/igniters, etc. pretty much orion's less bombastic little brother. the fission reactor is the thing that seems to be missing. both the us and soviets have flown actual reactors before, but never really saw a need to perfect the technology. i think all are still in orbit. there is kilo power which i haven't been following, but idk how far they are from a test article. with a decent power plant, nuclear-electric can really take off. fusion gets us another order of magnitude or two of isp. still quite a ways from an interstellar mission. you can probibly sidestep the need for the reactor for a test article, but an actual mission to the outer system will likely need it.
-
weeeeeeeeeeeee! i doubt she was the only one that wanted to test the slide, there was probibly a line behind her.
-
i actually believe that fusion drives are closer than fusion power. but since its not break even you need an energy supply, eg solar, rtg, or reactor. same problem most plasma thrusters have. there are so many that are stuck on the drawing board or in a trl rut because testing in space is simply not possible (the space station power grid may allow for some thruster testing, that was the plan for vasimir, but as far as i know that is not something that has been done before, since the grid is mission critical, eg life support). we need better space power.
-
early fusion drives wont be break even, they dont really have to be self sustaining. it will be nice to eventually tap them for electrical power, say for life support. that wont be until were at second or 3rd gen fusion power. but for now you just want fast charged particles. thus it has the same problem as any other electric thruster. its going to require some wattage. wheres do you get the power? we presently can get a few hundred kw using a really heavy bit of kit that doesn't work too far from the sun (the solar array on the iss). or we got rtgs which last decades on the order of half a kw and decreasing with age.

The Upcoming Movies (and Movie Trailers) MegaThread!
Nuke replied to StrandedonEarth's topic in The Lounge
dune2 was up on the high school sign, so that's what im doing friday night. i re-watched part 1 a couple days ago. ive read all the books but decided i dont need a reason to watch a worm movie. -
totm march 2020 So what song is stuck in your head today?

on todays stuck on repeat: heres the latest doomsday anthem from primordial. -
damn gremlins.

i think whats happened is that you are hearing about the usual aircraft wear and tear that always happens when you operate an airline. things that wouldnt be noteworthy by those inside the industry. but because boeing is under so much scrutiny it gets reported as more qc issues when its really a maintenance issue. this does not help their situation any.
-
i think elon may be jumping the gun here. i dont think we even are close to producing the perquisites for an interstellar mission, even an unmanned mission. you need: 1. propulsion, no engine no sane transfer duration. you need to get there before the ship is a broken down mess. see voyager 1. so you cant just use a really big fuel tank. 2. power. rtgs simply do not cut the mustard in either duration or power output. this also feeds back into 1 because you may need considerable power to say operate a fusion engine or plasma drive. if you have humans, increase power demands further. 3. systems with proven long operating life. humans have produced machines that in a good state of repair and with regular maintenance can last decades. but every part of the ship must be designed thusly. parts must also be shelf stable as you may need them to work flawlessly after a hundred years of waiting all without humans to do regular servicing. 4. a really stable government. administration 0 may be willing to pump billions into an interstellar spacecraft, but administration 100 may not want to spend millions building the dish to receive the telemetry later on down the line. as for the private sector look at how well pan am has maintained its fleet in 2024. pan am who? were they a thing? you see my point. you might have to do some religious engineering to make sure people get the payout down the line, because that's really the only institution humans have ever created which has legs.

control issues seems to be the major problem this time. im not even sure its strictly a thruster problem. it kind of looked like a calibration issue with the control loops. remember this is the first time we re-entered with starship and the first time the grid fins have been tested at low altitude. i saw a lot of over correcting going on. either they picked bad pid values or they were sweeping as many different values to see which ones performed the best.
