There's an interesting way ships launch in a videogame called final fantasy 8, where the ships start off launching attached from a rail that curves upward gradually and then they impulse really fast, still holding on to the rail vertically until they reach the top, let go and go at full force into space. I know it's a game, but Star Trek used to have a lot of scifi stuff that today exists, why not try a different launch method already?
I think the issue with a rail launcher is two-fold. The first is that humans just can't use it. The amount of acceleration you would need to make that kind of rail system feasible basically isn't possible without killing your passengers. Either that or the rail needs to be like hundreds of miles long. Second, the amount of power it would take to launch even an unmanned craft would be ungodly. It would easily surpass something like the HADRON super-collider, and that thing just accelerates particles. I can't even imagine how much electricity it would take to launch an actual craft. On top of that, it would be insanely expensive, be prone to breaking down, and probably be one of the most difficult engineering projects ever conceived. The attitude is probably that what we have already works pretty well, so there's not much point in changing it. Not unlike the "Space Elevator" project, the rail system is probably theoretically possible, but realistically, the materials don't exist to create it yet. I don't think FF8 invented it. I think it came from somewhere else first. Also, Ragnarok was the ship. I can't remember what the name of the actual rail launcher was.
***** _I can't even imagine how much electricity it would take to launch an actual craft._ Very little, actually. Orbital velocity is 7.8 km/s. To account for drag - both gravity and air - let's just round that up to a total of 10 km/s. Using the equation KE=1/2 mv^2, it will take 50 million joules of energy to put one kg in to LEO (low Earth orbit). There are 3 600 000 joules in 1 kilowatt-hour of electricity. Assuming $0.10 per kWh, it'll only cost $1.39 worth of electricity to put one kilogram in to orbit. Maintaining the launch facility would of course add to that cost, but that price would be more-or-less fixed, not appreciably increasing with the mass of the payload.
AlbertaGeek Dude, you're just assuming that there would be a direct conversion of energy from electric to kinetic energy. That is not how physics works. You're ignoring the actual, you know, device. If you want an idea of how much power something like this would take, look up how much electricity CERN uses on the super-collider, then try scaling that up.
***** okay, but... it's accelerating those things to very near lightspeed. This just has to make a ship hit escape velocity. The acceleration energy graph is exponential - the faster you're going, the more energy you need to accelerate further
God I love this channel. Thank you Caitlin, Hank and Reid for this valued information. Despite the at times hardly constructive criticism you all face, let it be known that your videos are viewed by some who do like what you all have to offer. Keep on for those. -BL
Caitlin you are awesome!! Thank you so much for the great presentation, info and for being an amazing woman promoting our further endeavors into STEM based studies. You're incredible!!
he ist the 21st century Hitler.... only instead of attacking Jews and other "types" of people 21st century Hitler will go for people who dont like how other poeple teeth look.... im screwed
The gas from that galaxy could also have been stolen by another nearby galaxy. This actually is quite common when lone galaxies get close enough to clusters of galaxies or other massive objects - they loose all their gas, thus permanently compromising future generations of starts.
Do some dark energy and dark matter, but in more detail then scishow did. There is more to say about it then what sci show said. I think this is one of the more interesting subjects of space, would be awesome if you did a few episodes on it
Actually I'm pretty sure the word of the day is "troll", and if something is bothering your sensitive preferences you're more than welcome to unsubscribe and fuck off.
I have a question about the spacecraft (X37B) you mentioned. What did you mean with "it runs on solar power"? Does it move using solar power, or does it only use solar power as electricity to run the instruments onboard?
Pretty sure it only recharges it's instruments. Though something makes me think that it has more than just the 1 main engine, otherwise, how do we turn it in space? Wings don't really help much up there.
Well, you need some kind of fuel to move in space, electricity alone won't make the ship move. The solar power is used to run the instruments and keep the systems online, so the connection to remote control the spacecraft stays alive.
A solar sail wouldn't be much good orbiting a planet when you are on the dark side half the time ;-) I don't recall any actual tests with solar sails either, but I can be wrong. X37B doesn't have solar sails either way :-)
if the US air force is involved, you can be almost completely sure there is an alternate motive, as long as scientists create new stuff there will be someone to weaponize it, my best guess would be an anti satellite vehicle, maybe something like the predator drone that can launch missiles at ground targets, it would almost invulnerable, and unmanned. they may have it up there "just to see if it can fly", but just add "so it can" and paste what i just said and that's what their really thinking.
GREAT episode. All 3 topics were fascinating. I now want to know more about this new shuttle. (if only there was some huge depository of free and easily-accessible information...)
Lol...that's so bad. But man, it's kinda creepy how at .5 speed she's still speaking almost normal. I guess she does talk fast. But yeah, Drunkin Caitlin is kinda funny.
At 2 speed she talks like most women when they talk amongst each other. Or it probably sounds like what men hear when they talk to us. BTW we like ya' Caitlin! Not picking. :)
Max West But think of all those light, simple elements, the red dwarf stars, drifting through the universe ancient and unchanging for more than 12 billion years. What could be cuter than that?
PinkGrapefruit22 A fennec fox. But anywho, I find the idea of those small, light, isolated stars really depressing. All that time just alone, no new light or heat to start great reactions. Just cold, dead ghosts.
We're literally just scratching the surface of mars. We should send a robot out there with a stick of dynamite. Blow a hole somewhere on the planet and then examine what was kicked up.
I'm curious what the significance of water on Mars actually would be. Would it just be an important discovery for our understanding of Mars and its development alone, or would it have more massive implications?? (Side note, Caitlin is AWESOME. A great host ^_^)
TicTac MentheDouce We already know Mars has a bunch of water ice, particularly on the polar caps. Most of the ice on Mars is water, with relatively thin layers of CO2 on top. The south pole has a CO2 layer all year, while the north pole's layer sublimates off during the north-summer.
3:40 I think you fluffed up a bit there. the heavier elments (iron+) are fused in the supernovae of massive stars. which generation of stars they are part of has nothing to do with it.
I really like the show but for the love for all that is good in the world please slow down your talking, it would be nice to actually process everything your tossing at us.
I actually find her easier to understand than Hank; I usually have to rewind his videos a couple of times before I can concentrate enough to understand what he's talking about.
isakoqv Its just the rate at which she speaks, especially in this video was just too fast at least for me. It felt like I had a whole bunch of awesome just flying past me like a great gust of wind. and on another note, I would really dig much longer and in depth videos both Sci Show Space and regular Sci Show. The topics they cover can easily be expanded upon for a easy 20 minutes.
she does seem to speak at a faster pace than Hank or umm the other new guy... sorry i cant remember his name.... heck i even forgot the name of the hostess in this video...
SciShow Space DIG IT! Only thing: Some background noice in there, and I'm sure it's not my headset. See what you can do about it, it set me off a little..
the new orbiter... reminds me of PlanetES .. anyone remember that great anime? We need ppl to clear the area around the earth rather soon, with all that space chunk in orbit :(
Does anyone know how many stars you need to define the cluster a galaxy and how far it needs to be from another cluster for it to be its own galaxy? or the scientific definition of galaxy and dwarf galaxy like segue-1 in this video, similar to what we did with pluto. (I am being pedantic just out of curiosity). Would intergalactic cluster with handful of stars or even one or two stars be defined as a galaxy?
Am I the only one who has a hard time understanding some of the words that Caitlin say? She's an amazing host, but some words can be hard to hear or at least understand. For example 0:50. Is she saying "the strangely layered mountain notice Mount Sharp"? I mean, English isn't my first language but I definitely understand other words and sentences! Anyway, Caitlin is a great host! Thanks for the video.
I hope she takes some of the feedback to heart and slows down a bit. English isnt my first lanuage either and also sometimes have a hard time understanding her.
Well I like to speculate...let's see: What would the US Air Force, part of the strongest military force in the world, want with a silent and almost invisible flying space drone?... Oh I have no clue!
Umm maybe it doesn't matter who is talking as long as you are getting new information? I thought this channel was about science and not some kind of fashion show.
Emanuel May Thank you. For some reason, a lot of people think Caitlin isn't pretty. I think that those people should go take a long walk off a short pier.
William Tannery The thing is: It doesn't even matter. What matters are the information that are transmitted. Yeah, she talks a bit fast sometimes, but so does Hank and nobody bats an eye then.
Ryan Harding I didn't see anyone argue in favor of censorship here. People are allowed to be assholes if they want, but that doesn't mean their opinions will be appreciated. You're confusing freedom from oppression with freedom from disagreement.
I'm confused about the 'fossil galaxy' (Segue-1). If it is 12 billion yrs old, and the universe is ever-expanding, how did it end up orbiting our galaxy? Shouldn't it be, like, 30 billion light years away?
Pretty sure dark matter is a conglomeration of exoplanets, rogue planets, and dark brown dwarfs and galaxies like that one scattered throughout the universe. Thoughts?
iamihop 3:40 also which generation of stars a star is a member of, has no influence on its ability to fuse heavy elements when it goes supernova. Lot of slip-ups in this video somehow.
+Silentsouls I'm sure people living in the late 1800's thought the same thing about electricity. Progression and discovery is what makes the world better and better all the time. We couldn't have made all the everyday-useful discoveries without having made breakthroughs like this. Also, do you want to stay on this planet forever?
This sounds dumb, but what if Segue-1 is a really old galaxy and the stars are just dying and the galaxy just kind of implodes? Or I completely forgot what red dwarves are
The most frustrating thing about astronomy to me is the universe's strictly enforced "look but don't touch" policy. :(
I love this channel. Thanks staff and people who brought this channel.

no offense to Hank but i love Caitlin explaining about space.
If I had some nickel for every different way I've heard the variation of the plural of "supernova", I'd be a significant portion of a planetary core.
I love that Curiosity is still chugging along, taking samples and reporting back! I'm interested in what the newest sample tells the scientists.
Caitlin, you're an awesome host! I really enjoy learning from you. Keep it up! :D
Thank you for being the first person to ever say "supernovae" correctly with the correct plural. Latin students can all breathe freely for a second.

Emanuel May Can't you have solar sails and use solar radiation to move the spacecraft, or is this technology just theoretical still?
A solar sail wouldn't be much good orbiting a planet when you are on the dark side half the time ;-) I don't recall any actual tests with solar sails either, but I can be wrong. X37B doesn't have solar sails either way :-)
Well for propulsion system you need 2 main factors. Energy and propellant. So it is clear that that solar systems are use to gather energy.
if the US air force is involved, you can be almost completely sure there is an alternate motive, as long as scientists create new stuff there will be someone to weaponize it, my best guess would be an anti satellite vehicle, maybe something like the predator drone that can launch missiles at ground targets, it would almost invulnerable, and unmanned. they may have it up there "just to see if it can fly", but just add "so it can" and paste what i just said and that's what their really thinking.
You're a great host! I always enjoy you're videos.
The Curiosity Rover be like, “...I got a rock.”
From what I understand, the X37B is part of Project Hot Eagle, which would partially explain why they have kept it in orbit for so long.
"They drilled into the rock ... and it ran away"
I enjoy both of the (relatively) new hosts.
GREAT episode. All 3 topics were fascinating. I now want to know more about this new shuttle. (if only there was some huge depository of free and easily-accessible information...)
3:05 shes so cute and enthusiastic about her work
If you turn the video speed down to 0.5 she sounds drunk. ^_^
It's so fucking true^^^^
turn the speed to 2 and try to watch the whole video without going insane
Lol...that's so bad. But man, it's kinda creepy how at .5 speed she's still speaking almost normal. I guess she does talk fast. But yeah, Drunkin Caitlin is kinda funny.
At 2 speed she talks like most women when they talk amongst each other. Or it probably sounds like what men hear when they talk to us.
BTW we like ya' Caitlin! Not picking. :)
You click the "settings" button (looks like a gear). IOts between the "CC" and "Window Size" button. In the list there should be a speed setting. :)
Great episode!
Caitlin, you're my favourite host!!!! Keep the videos coming :)
That's some super interesting stuff!
It's like a fetus galaxy! I don't know why I find the idea of a tiny, undeveloped galaxy so cute...
This galaxy was also a miscarriage... maybe not so cute.
Max West But think of all those light, simple elements, the red dwarf stars, drifting through the universe ancient and unchanging for more than 12 billion years. What could be cuter than that?
PinkGrapefruit22 A fennec fox. But anywho, I find the idea of those small, light, isolated stars really depressing. All that time just alone, no new light or heat to start great reactions. Just cold, dead ghosts.
Max West I second this. Fennec Foxes are amazing.
I have something that's tiny and undeveloped which you may find cute
Our galaxy is so metal \m/
Nice episode, Caitlin. Thanks.
I think the space plane is a probably a stepping stone to a weapons delivery platform.
We're literally just scratching the surface of mars. We should send a robot out there with a stick of dynamite. Blow a hole somewhere on the planet and then examine what was kicked up.
will the tnt explode without oxygen?
Im sure if we all pray to God really hard it will work.
S abre yes
***** Woah, dont need to be offensive, calm down, it was just a joke...
Someone seems to lack the concept of sarcasm...
I think it's kind of cute how NASA scientists name all the tiny rock formations along curiosity's route after scientists.
I'm curious what the significance of water on Mars actually would be. Would it just be an important discovery for our understanding of Mars and its development alone, or would it have more massive implications?? (Side note, Caitlin is AWESOME. A great host ^_^)
It could lead us to prove that their was once life on another planet and that us Earthlings are not alone.
Lots of water on Mars means previous possibility of life on Mars, and with other conditions, previous habitability.
ZeDecurser Vulcapyro Oh, duh! That makes sense. :) Thanks!
Might also mean that there is still water somewhere there, in another state, and that might be usable for missions there.
TicTac MentheDouce
We already know Mars has a bunch of water ice, particularly on the polar caps. Most of the ice on Mars is water, with relatively thin layers of CO2 on top. The south pole has a CO2 layer all year, while the north pole's layer sublimates off during the north-summer.

How is it exploring Mars still?

Can you do an episode on neutron stars
'it's flying to prove that it can fly'........hahahahahahah
Wow miss Motor mouth. I swear she's sitting on a V8 to talk that fast. lol. Didn't know about the new ship though.
So what generation is our galaxy? And how many generations can galaxies go through?
I actually did not like either host at first, but both are growing on me. Keep up the good work!
Could you guys explain what a brown dwarf is in a future episode?
so more or less, we will find namekians somewhere in Segue- 1... Awesome! :) Lets go get me some dragonballs.

Nasa always have the cuttest names.
Hank!!!! Not a Green!
I love her voice
"It's flying to prove it can fly"
Seriously guys, you can come up with a better cover story than that.
It may be a minor point, but stars don't become more massive by fusing elements in their core. I don't know why she said that.
iamihop 3:40 also which generation of stars a star is a member of, has no influence on its ability to fuse heavy elements when it goes supernova. Lot of slip-ups in this video somehow.
They couldn't wait until after they end running the test, to tell us if that is or not sand?
They know it's sand, they just don't know how it became sand.
Cool
Damn so close
used to not like her but her talking about space is hawt
I wonder when they'll put some crew in the x-37. I would like to hear if the ship grows.
