Space-themed TV shows (that care a little about realism)?
Nikolai replied to Nikolai's topic in The Lounge
I think part of the problem seems to be that you're accepting it as a given that NCIS is a "realistic" cop show. If so, I think you're setting the bar for "realism" rather low. Not that there haven't been realistic cop shows. Dragnet was about as real as could be squeezed into an episodic format, and it did well for years, both on the radio and on television. And again, for the reasons I cited, I fail to see why those reasons are particular to realistic science fiction. The hurdles are higher, yes, but I do not think them insurmountable. -
Um... wut? Seriously? If you want to compare apples to apples, consider the return of science on the unmanned versus the manned programs to the Moon in the late 1960s and early 1970s. The manned program cost more, yes, about a hundred times more -- but it returned far, far, far more than a hundred times the science. Steven Squyres, scientific leader on the MER Mars rover missions, was often referenced after he pointed out that the Mars rovers could do in a day or more what it would take a trained geologist a minute or so to do. (And that excludes other things that humans do that, for machines, is simply impossible.) Ultimately, the entire point of space exploration is to find new places to live (as well as develop the technologies needed to live there). After all, we know there are (albeit rare) catastrophes that could wipe out all human life if it continues to exist on one planet, and that we're rapidly inventing more and more ways to do serious damage to our species' livelihood with nowhere besides Earth to conduct our tests. That enterprise -- vastly increasing the odds of human survival (and the survival of other kinds of life) by spreading out -- is doomed to be left with certain fundamentals left permanently untested if humans never try.

Travel at, sure. Why not fight at those speeds? On the show, I rarely see them fight while moving faster than a few meters per second, never mind tens or hundreds of thousands of kilometers per second. I'm familiar with it. But one maneuver doesn't impress me all that much. Why not explore the logistics of fighting where both spacecraft are maneuvering at higher fractions of light speed? This changed warfare in the air. In WWI, fighters generally got into a furball with perpetual shooting until someone went down. WWII saw the advent of faster and faster fighter craft, and this changed dogfighting into cycles of encounter-maneuver-encounter-maneuver, with the "maneuver" cycle lasting longer and longer as planes got faster and faster. Missiles changed the game again, and if it ever came down to a dogfight (missiles having been expended), the speed of jet aircraft meant that there were often minutes taken up with the "maneuver" cycle. (Planes fighting it out over Korea had to be careful not to overshoot the country's boundaries!) Now, in the future, you have faster and more intelligent computers (which would doubtless be incorporated into the weaponry) and much faster starships. Starships equipped with inertial dampeners, yet, if we're willing to be handwave-y with the physics. It seems to me that this would change the game yet again. Still, the kind of battle tactics I see have more to do with ancient Roman naval warfare than anything that helps us to realize just how different the environment we're talking about is. Well, if we're going to be that general, why not point out that all conflict falls into broad categories and is always boring? "Oh, it's another 'man vs. man' plot, followed by another 'man vs. nature' plot, followed by another 'man vs. self' plot, and finally, a 'man vs. society' plot. Can't they come up with anything original?" Part of the problem, I think, is that we're not used to things having consequences for more than one episode for anything other than interpersonal conflict ("soap opera plots"). But it doesn't have to be that way. Conflicts are not frequently resolved quickly in the real world, and even whether or not they are resolved can be an open issue. Consider Apollo 12 (the actual mission). They had a problem on launch (the rocket was struck by lightning twice during ascent), and they were unable to check whether or not the pyros that would open the parachutes were still in working order. They knew that when they brought the crew back, there was a chance that they would fall into communications blackout and never come out (hitting the ocean at high speed). That's kind of an extreme example, but it's the sort of thing that generates dramatic possibilities for more than one episode. But we're not used, as an audience, to having technical conflicts that have lasting effects. I disagree that keeping things realistic forces us into a repetitive corner. (Of course, one can always say "And then what?" until creative ideas are exhausted, but I maintain that that's true for any genre; it's not a particular weakness of realistic science fiction.) At the end of the day, my point is not to bash anyone's favorite sci-fi franchise. It's to point out how difficult this is, but that it's clearly not impossible (since examples do exist, and I'm always hoping someone has found more that I'm not aware of), and to bemoan the fact that there aren't more of them (to scratch my particular geeky itch -- my brain likes to be entertained, too, really). -

I respectfully disagree. Part of what makes space travel exciting is that it is a *hazardous environment*. The dangers of space travel need not be limited to (a) radiation and ( aliens with ray guns. The very fact that we need to rely on our cleverness and our technology to survive can be exciting in and of itself. It's not even the case that the *actual* space program was limited in problems to radiation, and our imaginations can come up with problems we never actually faced. Your other point -- that TV shows tend to keep running until the ratings falter -- is, I'd argue, a weakness in the way we do many TV shows here in the States; it imposes limitations on *any* drama, not just realistic science fiction. (And novelty is not exactly a cure-all, either. There are countless shows that introduced a new cast member when the ratings were relatively strong and promptly lost their faithful audience.) The fact is that accurately representing circumstances that are quite far removed from everyday experience is *hard* (never mind bringing your audience up to speed). I suspect this keeps more TV producers out of the subject than the limitations in setting. EDIT: Everything below came from a sudden flash of memory. Consider "Planetes", which I mentioned at the start. It's about a group of orbital debris collectors, and they're based on a space station, but they still find room for a lot of variety -- different locations on the (somewhat large) space station, visiting family back at home, taking a vacation to an underground Moon colony... and one of the main characters ends up training for the first manned mission to the Jovian system, so there's the training facilities, the ship's drydock in orbit, and on and on. Just because the series features main characters employed by a more robust space program than any currently on the planet doesn't mean that they were stuck with "sit[ting] in the same spot with the same problems occurring over and over". -

So why don't they fly around at 0.25 c while fighting? The tactical advantage someone might be able to get by moving slower isn't that much greater. Or even 0.01 c? (I assume they aim with computers or something, since aiming at something moving at close to light speed when you're traveling at 0.25 c would seem... difficult... otherwise.) Or do they just conveniently ignore that? What about the "huge tactical advantage" created by the positional uncertainty involved when someone's traveling at close to light speed relative to you? Or do they just conveniently ignore that? This seems to be handwaving. "We know there's this problem with physics with what we're describing, okay? So there's this... *thing*... that takes care of it. See? No problem." Kind of like the "Heisenberg compensators" in Star Trek's transporters. I appreciate that they're throwing me a bone by recogizing that there's this apparently insurmountable problem in doing what they want the people in the show to be able to do, but let's not kid ourselves. They're ignoring physics when it's convenient to do so. Hyperspace is more of this kind of handwaving. It allows them to circumvent a problem with physics by inventing a storytelling mechanism. And sometimes, those technologies violate physics as we understand it. For example, Heisenberg compensators *should not be possible to make*. We're not talking about an *engineering* problem here, like "We can't imagine material strengths that could survive traveling through the atmosphere at supersonic speed." We're talking about a *laws of the Universe* problem here. Think of it another way. Conservation of mass-energy is, as near as we can tell, completely inviolable. If a show existed that could, through some unexplained mechanism, violate conservation of mass-energy, allowing the characters to make golf balls by sneezing (in a plot and setting where golf balls are extraordinarily handy to have), would that seem to be an "explanation"? Of course, I can enjoy these shows because I like the stories, even if they're physically impossible. But it's a mistake to think that, for example, Star Trek explains how stuff works in a way that's consistent with science and merely has more advanced (and currently inexplicable) technology. Of course, it's completely possible that I've misunderstood your point. Please feel free to set me straight. -
How about television shows that try to be accurate when it comes to what space travel is actually like? Sadly -- especially considering how many TV shows my own country cranks out -- I can only think of Japanese ones: * "Planetes" (and yes, there's an extra "e" in there). It's set in 2075, when space travel is much more routine, around a group of people whose job it is to recover debris in orbit to prevent it from becoming a hazard. They're so careful about the science that rocket engines are silent and laser beams (used for range-finding) are invisible, and one can hear occasional accurate descriptions in the background of "transfer orbits" and such. But it's not just for space geeks -- the main characters are very well developed, to the point that I was tied up in knots over the moral dilemma one of them found herself in near the end of the series. * "Space Girls". Yes, it's another "Japanese school girls can do anything" show, but man, it's just *fun*. It revolves around a company who wants to send people into space from the Solomon Islands, but has to keep shaving its weight margins more and more until sending a full-grown adult is simply not an option. Yes, it's a far-fetched premise, but if you let that go, most of the rest of it is really solid stuff. It also succeeds as a whimsical comedy, and I genuinely enjoyed watching the main character go from a bit of a flake to a responsible mother hen (the company ends up hiring three teen girls as astronauts by series end). Anyone else have recommendations for people eager to see something in realistic television shows set in space?

Yeah, I saw it as a kid. Even then, I was much more interested in Kathryn (the ambitious wanna-be commander, played by Lea Thompson) than Tish (the Valley girl, portrayed by Kelly Preston). I still think smart and capable women are much more attractive than those who "play dumb". ... But not a great movie. FWIW, I recently saw "Countdown", which attempted to be much more "realistic". It was based on the Pligrim Project, a proposed (but never seriously analyzed) plan to beat the Soviet Union to the Moon if closing the technological gap proved more difficult than imagined -- the idea being to land him in a Mercury capsule and send him supplies 22 times a year until a way could be devised to bring him back. http://www.imdb.com/title/tt0062827/ It's interesting to note some quirks -- for example, the mountains on the Moon have craggy peaks, which we kind of assumed they would in the absence of erosive forces we were familiar with on Earth (like tectonics and weather). Anyone else know of attempted realistic space fiction in movies?

<pictures snipped> I had something kind of like that. I landed on Mun successfully, and wanted to show off to my kid. Unfortunately, the Kerbal himself disappeared between the landing and when I started the program up to show her. So there was a rocket there, but no Kerbal. Oops. (Maybe I clicked "End Flight" instead of "Space Center"; I'm not absolutely sure.) But I had a rescue pod on Mun if I needed it, and that was good, right? So I mounted another mission to Mun, but cut off the landing engine too early and fell the last three meters or so. The impact was enough to split the lander into two parts: (capsule + ASAS) and (everything else). The capsule and ASAS slid a few centimeters on the rest of the stack and stopped, balancing delicately in place. But I had a rescue pod, only a bit over 40 km away! So I could get my hapless pilot home after all. I just had to get him to the spare lander. With Minlun Kerman just outside the hatch, the capsule was now imbalaced enough to fall completely off the stack -- and it did, with Minlun smooshed underneath. The lander had landed on an incline, though, so the capsule and ASAS just rolled off down the hill. Minlun was flat on his back, but alive. Forty kilometers is a long hike, when it comes down to it; I thought I'd cheat just this once and give Minlun infinite EVA fuel. After getting him up and dusting him off, I powered up the jetpack and sent him flying over the surface. It still took quite a while to get to the abandoned lander, but I managed to arrive in one piece. It turns out that my rescue lander didn't have enough fuel to escape Mun's SOI. My girl had been watching me for quite a while by this point -- she's extraordinarily patient -- and I really didn't want to crash after everything Minlun had had to put up with, so I turned on infinite fuel for the lander and powered my way back to Kerbin. Speed up time, let Kerbin get huge in the window, slow down time again. Get to about 60,000 km up, where I realize that I had failed to include a decoupler to separate the capsule from the rest of the lander. Rookie mistake! Fortunately, I was headed toward the ocean. I used my parachute and my lander's engine to slow the descent; thankfully, the entire lander floats. So Minlun returned home safely with a few bruises and such, but only because I cheated. I expect that if I hadn't, this would have ended in disaster in running out of EVA fuel while riding over Mun's surface at high speed, or if not that, with an emptied rescue lander impacting the Mun's surface. Or if not that, then a lander smashing itself to bits falling into the ocean under a parachute that was too small. All in all, it left such a bad taste in my mouth that I had to re-design my main rocket to carry a lander large enough to get back off the surface of Mun after landing there.

"Precision Control" vs. "Instant Control" Mode?
Nikolai replied to Nikolai's topic in KSP1 Gameplay Questions and Tutorials
Thank you. Does this mean that I will only see the difference if I have an RCS installed? Or will I also see a difference with (A)SAS attitude control? -
This is AMAZING. Thank you for sharing! (Minor nitpick, and it's only if you care -- this animation gives Kerbal an axial tilt, which it doesn't have in the game.)
-
1000 times, actually. Density is inversely proportional to VOLUME, not diameter.
-
Are the Mun and Minmus tidally locked? I ask because I've landed successfully on Mun for the first time (I went to Minmus first to take advantage of the gentler gravity while practicing my backing-into-large-rocks technique). Kerbal is on the far side, though, and I want to know if it will stay there or if a more fuel-efficient alignment will occur.
-
That's funny. I thought it sounded like Bart LaRue.
-
I've used the skidding-on-the-ice trick myself -- the kids think it's a riot. ("He's ice skating with his face!") I also noticed that trying to jump on a steep slope will cause the little guy to lose his footing and slide down the hill (in a standing position). If where you need to get to is downhill, this covers distance at a pretty good clip. (Unfortunately, I discovered this while trying to head uphill, and lost about 700 meters of ascent in a minute or so.)

Is there a way to remove space debris?
Nikolai replied to Nikolai's topic in KSP1 Gameplay Questions and Tutorials
Thanks for your reply. In my experience, though, Option (2) is only possible if there's still a Kerbal aboard; the menu that includes "End Flight" doesn't even come up otherwise. Is that true? Or am I doing it wrong? -
I have a lot of spent rocket stages in permanent Kerbin orbit, and even a handful that have been ejected from Kerbin orbit and are now orbiting Kerbol. It's starting to really drag on my system, and it makes maneuvering in the orbital map near Kerbin challenging at times. Is there any way to clear these things out? It's kind of cool to have orbital debris to attempt to fly to/around, but it becomes a real swarm all too quickly. Thanks for any insight you might have.
-
Me, too. <scrathces head> Sorry about that, HOC. Even in spite of my confusion, your kind words are appreciated.
-
This is simply stunning. I can\'t help reading just to see what\'s going to happen -- the character you\'ve made is such an excellent balance between unpredictable and chillingly believable.
-
Thank you, Vostok. Yes, it is, with the exception that there wasn\'t enough fuel left to break Minmus\' orbit. The craft is still in a long, looping orbit around the moon, three of its four landing legs still extended. (Regrettably, the Gassy Guppy III was an actual flight as well.)
-
Thanks, Commander. As XenonBlade pointed out, there are a lot of things that don\'t make sense about this flight. I was hoping to get just a hint of the 'Let\'s try stuff and see what happens', jut-jawed, two-fisted Conquest Of Space that this game captures so well, where safety and caution are very secondary.
-
This is just a quick little draft I wrote to see if I could get a quick, surface-level sketch of the characters before trying to write something deeper. Please let me know what you think. -------------------------------------------------- The engineers were happy. To a saner mind, this would have been a warning sign. Few engineers are willing to clamber aboard their machines and learn about their individual quirks, especially if the machine in question is preparing to shove a Kerbal faster than any Kerbal had a right to go. That special level of crazy required a test pilot. Jebediah looked up at the engineers\' latest creation and grinned. The only reaction of the gleaming tower was to click, hiss, and moan as refrigerants evaporated and valves opened to vent them. 'How fast?' he asked in measured tones. 'Escape velocity, at least,' came Myrtle\'s reply. She glanced at her clipboard. 'Three and a half kilometers per second, give or take. You\'ll need to have that much push to get all the way to Minmus and back. Bottom line, though: There\'s enough oomph in this baby to leave our planet behind forever. You\'ll be the first Kerbin to pilot a machine with this much power.' 'Sweet, holy Meander.' Jeb donned his favorite sunglasses, never removing his gaze from the tiny capsule perched on top of the monster. It was a while before he spoke, though his grin showed no sign of fading. 'I\'ll need to collect my crew. Get ready to push the Big Red Button.' *** 'But is it safe?' Bob demanded. 'I\'ve seen the Ker-Sproing Alpha I myself. Up-close and personal. It\'s a thing of beauty,' Jeb replied. 'But. Is. It. Safe?' Jeb sighed. 'It\'s a stinking rocket, Bob. It\'s not supposed to be safe. You should have learned that after our flight of the Gassy Guppy III last year.' Bob remembered. The engineers had underestimated how much thrust they would need in the second stage. Less than fifteen kilometers up, he couldn\'t take his eyes off the altimeter as the rocket slowed, stopped, and began falling back to Kerbal -- backwards, the engines still roaring under full thrust. The last thing he remembered was watching rocket exhaust fly up past the capsule windows. According to the post-flight briefing, Jeb had kept his cool and pitched the rocket over, allowing them to jettison the capsule and parachute back down safely right next to the water tower. If Bob hadn\'t passed out from terror, he probably would have learned a lot about rocket flight. As it was, the only thing that really stuck with him was the lesson that bleaching urine stains out of a flight suit was harder than he had first expected. Space-age fabrics might look good on camera, but they stain all too easily. 'Say what you will,' Jeb said, interrupting unpleasant memories about a long hour spent in the space center\'s laundry room. 'That thing may not have flown well, but she gave a smooth ride.' 'Comfort all the way to the crater,' Bob muttered. 'What was that?' 'Have you trained?' 'Enough to keep your little green butt safe. I always do. Don\'t worry. I\'ve got your back.' Bob sighed. 'All right. I\'m in.' *** 'Why Minmus?' Bill pressed. 'Why not Mun first?' 'Because Minmus is further away. That\'s automatically cooler.' 'Take off your sunglasses,' Bill said. Jeb complied. 'Look,' he said. 'Minmus offers us the opportunity to figure out how to land tail-first in a safer, low-gravity environment. Sure, it takes longer to get there, but it\'s better than finding out as we plummet towards a heavier body that the rearview mirrors don\'t work right. \'Objects In Mirror May Be Closer Than They Appear\' and all that.' Bill snorted -- a tricky sound to make when one has no nose. 'Fine. But wouldn\'t it be easier to wait until the scientists figure out docking first? We wouldn\'t have to worry about planting something down gently that was also big enough to bring us all the way home again. Just saying. It would give me time to go on a vacation with Sylvia.' 'You can wait if you want,' Jeb answered. 'But Minmus has these enormous ice fields. Your figure-skating girlfriend would be impressed. She\'d probably even find it romantic.' Bill opened his mouth to protest, then closed it again. 'Fine,' he said finally. 'Let\'s land on Minmus.' *** Fiery-red Kerbol was just beginning to rise over the Kerbal Space Center when the main engines ignited under the Ker-Sproing Alpha I. A compression wave rippled up the length of the rocket and snapped out the top. Before Bob could even open his mouth to scream, the beast lurched off the pad and began sliding towards the sky. Almost before they\'d cleared the tower, the rocket began to sway -- rocking to and fro as the SAS attempted to compensate for fluctuations in heading by slamming the winglets from one extreme to the other. The oscillation was enough to shove the poor Kerbals from side to side in their seats in spite of the harnesses. Jeb swore and put his hand on the abort handle. 'Could be a short flight,' he observed. For his part, Bill was frantically stabbing out alarm lights as the computer complained about guidance. 'I think this will damp out once we get out of the lower atmosphere,' he said without looking away from the instrument panel. 'Our radar can\'t keep a constant fix on the ground, but I can still see figures every once in a while, and our trajectory looks right on the money.' Bob started freaking out, loudly. Jeb swore again and apologized to Bill. 'I planned ahead, really I did. I was hoping this would be a quieter flight. Unfortunately, I left the sedatives in my duffel bag.' 'Where\'s your duffel bag?' Bill asked. 'In the White Room, next to my locker,' Jeb replied. 'I guess that means that if this rocking keeps up, I may need to borrow your comb in a bit. It\'s messing up my hair.' After a few tense moments, Bill\'s prediction turned out to be right; the rocking slowly began to dissipate. Jeb released the abort handle and started to steer towards the east. 'We should be in orbit shortly,' he reported. 'I\'ll be following the path on your display, if I can.' A bang rattled the capsule as the first stage separated. A second bang signalled the ignition of the second stage. 'Muuuuuch smoother,' Bill said appreciatively. 'It\'s like I always say: One engine is better than six.' 'Speak for yourself,' Jeb responded. Even after orbit and MECO, Bill looked concerned. 'I can\'t get a good status on the \'chutes,' he confessed. 'I think they might have been damaged during ascent -- but it could just be a faulty sensor.' Jeb thought about this. 'Well, if the parachutes are shot, we\'ll be dead if we go home. And that\'s true whether we go to Minmus or not.' He grinned at Bob, who had gone hoarse from shouting and was now emitting little squeaks. 'Just try not to think about it, okay, Bob?' *** It was several days\' cruise to Minmus. Jeb ended up steering the craft into a highly elliptical orbit inclined to Minmus\' equator by more than forty-five degrees. 'I\'m going to try dropping straight in from periapsis,' Jeb announced, 'with periodic bursts meant to keep us from picking up too much speed.' He locked in the capsule\'s heading so that he would be able to fire against the rocket\'s direction of travel when they got down to that altitude. 'Wow,' Bill exclaimed. He leaned over Bob to look out the window. 'It\'s... it\'s amazingly weird, isn\'t it? I\'d have expected sharper peaks on something without erosion. Why do you think all those features are rounded off?' There was no reply. Bob continued to squeak. 'Why do we take him along, anyway?' Bill pressed. Jeb shrugged. 'Space is quiet. I don\'t like it when it\'s too quiet for too long. Besides, he reminds me of my parakeet.' The minutes to periapsis passed quickly. It wasn\'t long before the kerbonauts felt the familiar kick in their seats associated with a rocket firing. The altimeter quickly started to tick off the meters as the vessel sank. As promised, Jeb only fired the engine every few hundred meters to slow their descent. Before long, it became clear that the rocket would set down in one of the enormous ice lakes on Minmus. Bill leaned over Bob again. He looked at the nav ball to verify that they were headed straight down. 'Um, maybe it\'s a trick of the mirror, or maybe the rotation is faster than we\'d thought,' he said, 'but we seem to be moving sideways a lot faster than I expected.' 'Don\'t worry about it,' Jeb said. 'The gravity here is pretty light. We may skid or bounce a little, but we\'ll be fine.' As if to punctuate his remark, the landing legs smacked into the hard surface. Unfortunately, they were moving sideways so fast that one of the legs snapped clean off as the capsule slowly bounced back up. Jeb sighed. He had time to react as the craft traveled a slow arc and began to head back toward the surface. 'No landing this time, I guess,' he said flatly, and rammed the throttle back up to full, punching the trio back into the void. *** Several days later, the parachute worked perfectly. And Bob was finally awake and quiet at the same time. As the capsule drifted towards the water, Jeb started a mental checklist of things to ask the engineers to add. Maybe another fuel tank in the second stage to increase their margin for error when they finally arrived at the small moon? Maybe that would work. A few other things would be needed before they flew the Ker-Sproing Alpha II, but the basic design seemed decent enough. It got them there, didn\'t it? Bill was trying to work out the wording he\'d need to apologize to Sylvia and minimize her 'angry time'. And Bob was counting the change in his pocket and making sure he had enough for two washes.

Perhaps it\'s your illustrations, but with the alphabet system I see, it might be easy to confuse a hastily-scribbled 'G(e)', 'O', and/or 'U' (and even an 'I', depending on the penmanship of the individual Kerbal). They\'re all closed shapes with little to distinguish them but number of corners (and corners can, unfortunately, be rounded) and orientation. I can recognize an 'O' in my alphabet regardless of how poorly it\'s drawn, for example, in part because there\'s nothing that looks a whole lot like an 'O' (only smaller). Of course, for all I know, maybe Kerbal brains work in such a way that they instinctively look for visual differences our human brains tend to gloss over. Or maybe their language is such that deciphering the correct letter is easy with contextual cues. All that said, please take this as an extremely minor critique. I really enjoy what you\'re doing here -- building a script with a history! It really adds flavor and depth to Kerbal history prior to the space age.
