Watch out if Eros starts moving towards Earth. (all by itself)
Especially if there's a radioactive fungus growing out on Eros

That was the plot on the new Lifetime special 'What's Wrong with Phoebe?'
The answer is nothing but she did good on Charmed.

The SCISHOW compilations are my FAVORITE VIDEOS on RUclips lol caps bc I'm so excited🎉😂
Caitlyn is so happy and I love seeing her host. Great channel and interesting topics.
Patronizing is best through Patreon these days. -_-
@@josephdonais4778what do you mean?
2:00 I'm currently helping out with Asteroids@Home project on boinc that simulates asteroids physical properties (shape, rotation period, and direction of the rotation axis) by using the data from all-sky surveys and simulates the lightcurves to determine all of that
The photo you got came from that project :D
They weren't joking when they said it was time consuming to calculate the lightcurve. Right now my GPU has to compute ~1.4mil GFlops on each task given to it
Learning about Hayabusa burst into flames so we can learn a thing or two from that made me tear up.
waiting for some updates on these... gimme asteroid-powered rocket fuel stations
Right!
Use the rock as exhaust
@@amberwalsh5767😅iobggggggg 👋 you
The odds of successfully navigating an asteroid field isn’t 3,720 to 1?
never tell me the odds.
IRL it's like 1:1. You still have to try to hit something to end up anywhere near anything, even in the asteroid belt. And yes I know you're making a star wars joke! It was funny.
@@hnr9lt-pz7bn That is true! I guess I was thinking about already being in space and just the traversing the belt part.
"Never tell me the odds..."
Shirley u jest
Why is it that I only see Hank Green in videos from 8 9 or 10 yrs ago. All the ones that are new he is not there. That really is upsetting. As he with his knowledge and humor, is the only that kept me watching Sci Show all these years 😢
He's undergoing chemo for Hodgkin's Lymphoma & probably a lot of his time is taken up with feeling like utter crap after treatments. He's also just crazy busy, working on several channels at once, a record company, writing, music, doing talks & conventions. And now with the cancer diagnosis, he's got his health to consider. Don't worry, he's still around, just more in the background for now.
@@DrachenGothik666 Thank you so much for letting me know, I will pray for his recovery 😪
@@DrachenGothik666nah he still pumped out tons of videos during the chemo. They _did_ expand their number of hosts since back then. So they all seem to record a few and post in chunks.
@@darlenelang3681also hes doing well.
Hank an his brother do weekly ,shorts - John is fun funny two ,too ,also ..he's all over search around
Love you hank
Very interesting
I’m so excited to find out what was on that asteroid Osiris-Rex sampled! It’s coming back soon!
I could imagine a day when people want to establish a long-term or permanent mining and industrial outpost would do so on an asteroid. Actually, for protection from radiation, it would be best to build their facilities underground or burrowed into the side of deep craters or other vertical terrain. It would have to be one rich if materials needed to extract oxygen, water, and materials for raising food, and with luck enough metallic minerals to construct habitats and other needs. From underground habitats, extend structures for docking spacecraft and transfer of materials and humans and which also deliver rocket fuel for return trips or further exploration. I know, sounds like a pipe dream, but it's these dreams that can lead to new ideas that do product the technology needed to accomplish it. Ad astra!
“The value of these asteroids!” *immediate flashbacks of Don’t Look Up*
exciting
Given the sort of timescales expected with terraforming and automatic/self-constructed megaprojects, one really great way of using asteroids is to heat it up until molten, then slowly spin it up and allow dense materials to centrifuge out. Then use a passive radiator to cool the rest of the asteroid back down - bam, solid rock with many of the useful materials removed.
I guess if that were true wouldnt all the metals be on the surface of the earth not in the core?
Even with a extremely viscous melt this would require a hard shell of refractory high tensile strength materials that keeps it from scattering into drops from an already red hot donut
A friend worked for Planetary Resources- they went defunct in the actual exploration years ago.
Well done Nigel.
Any chance you would be willing to ship samples for tasting? : D
Cheers from your neighbour in Ontario
What would it mean if they found plastic particulates in astroid water? : )
Space capitalists

Cosmic rays and the need for artificial gravity are the primary challenges, so...
One thing cooler than 3D printing asteroid material in space could be feeding & housing everyone in the world
You're on the wrong channel to complain, NASA has about 1 percent of the budget that the US military does
Asteroid mining? Jupiter Mining Corporation?
And this is precisely the reason why i don't think any mars or any near future planetary colony will ever exist or exist for long. Because economy ultimately drives long term expansions and there isn't anything we can get from mars or any rocky planet for that matter(except earth) that we cannot get from asteroids far more easily.
Here drink this! Where did you get it? Off that asteroid floating in space. Naw fam…I’m good
Dawn ran out of fuel, stuck in a stable orbit, but doesn't it randomly face the sun and charge up a little?
Astroigloo's ftw.
At the moment it’s entirely more efficient if we ship factory’s into space instead of earth based to launch pre built satellites or structure into space. It make more sense to build with asteroid in space. But this cannot be the the best solution, we are missing some obvious advantages by simply not know the right questions to ask.
First part: Mining materials in space to bring it down to planets.... even, if that isn´t mentioned in first hand (because for space stations), at the end of the lecture of that man, he speaks about stations on Planets. The problem to that is, that the metals in asterioids often had isotopes contained, that aren´t stable in gravitation (or other condition, that is usual on planets). So they decay through the transport to the surface (for example Platin191 to Iridium191 over electron-capture, as it may happend at the event, that killed the dinosauers 66 mill years ago - for that there was iridium in the asteroid, there is that unoverseeable layer of iridium in geological layers around the world and is connected to the impact. Albeit: not the iridium was in that asteroid, but platin191). So if they once transport random metals down to surface of a planet, they may initiate the explosion of a natural nuclear bomb. Albeit it is unclear, why that electron-capture happends. Maybe it is a interaction with atmospheric electric tension/potential, not gravitation (albeit it is until today not clear, what gravitation realy is - some fabulate, that this is not a physical force, rather a "space-time"-effect. The idiotic part of that account is, that even if that were true, it effect forces to matter, so there is force - in classical physics, also there is no motion without an initiating force or potential). And if the planet didn´t have propper atmosphere (as the moon or mars), maybe nothing happends. The only problem, that lasts, is the problem with the masses and the gravitation, that makes it complicated to land on planets with asteroids or even only mined ore.
And there is anohter apprehension: The question, why earth has such a special atmosphere, also isn´t clear explained. Maybe it is all evolved, because of live in oceans, that evolved million years along and then, that life formed two things: Plant-life produced oxygene, what filled the atmosphere. And the other thing is, that such a special atmosphere was catched by neurological fields, that evolved also parallel to evolving of life in the oceans. So.... both pre-conditions for life on land. Whilst ocean-organisms did not need the atmosphere. The conclusion of that thought is, that, if you colonize humans on mars, you may get a manipulated atmosphere, that can influence earlier plans to mining metals from asteroids, because of electron-capturing happends, because of atmospheric potentials, that will change with the amount of humans on mars.
And if that thought is right (more or less), it also has consequences for the science of climate-change, because of if neurolgical activity can influence such things, it also can regulate conditions, whereout a problem, like climate-change/warming, can emerge. Some would say, that all that is really wrong and totaly over all scientific expertise and knowledge. And, maybe it is. But:... scientific knowledge is not, what realy is (or can be). It is only the actualy knewed knowledge about reality. And there are maybe big holes in that knowledge until today. I am shure, that this is the reality of todays science. And there are maybe more forces, as we know of today. Maybe forces, that not came out of material existances, rather forces emergend out of potentials and other physical conditions and beings.
Was April an Irish dancer growing up?
Are these reruns of old videos?
Yes, it's a compilation video
12:18 end of 2018? How old is this video?
These'd be even better if you hadn't nuked SciShow Space - and don't get me started on what WAS my fave channel of all time: SciShow Psyche...
I’m more of a city Belter myself 👍
President Clark is still centuries from being born (B5 reference), but maybe we could skip that whole story?
Yeah didn’t handle that whole first contact thing very well for us.
@@OneBentMonkey then again, seeing that the Ancient Aliens guy was literally the first one we met might have had a weird effect.
@@ponyote If they just want to show us how to move big heavy rocks into a ginormous triangular pile, I’m all for him being our first contact liaison 😂
I think I fell into total infatuation. Caitlyn that is.
Why aren't we sampling meteors from the craters of the moon?
Wait, is this a repost?

We need to humans to get to space
Reconsider the name of this video. I watch this channel because I love to learn about new stuff, especially about space exploration. “Why should we care” is a weird way to frame this topic. It is like you are starting from a place of saying that well this topic might appear to be boring or unimportant research. Again that is a weird start to a video aimed at people who are curious and love to learn.
It's probably intentionally click-baity to get new viewers.
No, unfortunately, lots of people can’t see any point in it. The amount of people I meet who don’t have the energy is terrible enough, the worst part is that the people who have the resources to be able to do this stuff usually see no value in knowledge for its own sake.
Honestly I've always been a supporter of the space program but we need to fix our mess, not escape it.
They could really be one in the same. If we could offload heavy industry to orbitals? Or get minerals from asteroids instead of chewing up miles and miles of the earth?
A lot of future tech is locked behind the ability to gather certain minerals that are difficult, or just very expensive on earth but are abundant in space rocks.
Honestly, this is something I've been looking forward to since I was very young.
@@KodeeDentares could be? Maybe but in our current political climate it's likely to be the most dystopian version of whatever you imagine
"in 2016"
Ugh, this is old then.
I thought she looked a bit younger than I remember. 🤔
I was also caught by this. Oh well, humans made it back safe from space today. One day this sentence wont be special. :)
That craft hasn’t even returned to Earth yet, but it will be back soon!
Oye beltalowda
Its old video? This is pre 2015
Ah

This comment is for 11:15 in the video. Apparently they discovered Marvel's Universe Venom symbiotes, or the shadow of evil from the Next Generation Star Trek.🤨😅✌
Kaitlin (sp?) talks so fast I needed captions and constant pausing to understand her.
You can slow down the video. Just hit the gear in the top right
I been telling Elon Musk for years now, that this should be his next business. Asteroid mining.
u trust elon musk with asteroid mining?!? the man couldnt even handle twitter
still no first?

I think you were first, when I clicked it had 3 comments, and yours said 6 min ago, while the other two said 5 and 4 min

now if i was a real conspiracy theorist, this show would lwad me to believe that the 1950"s movie the Blob wasn't Sci/fi but had its origins on the asteroid Ceres.
Nothing new? Another compilation?? Omg, can you please use a playlist instead of milking your audience for clicks?
The compilations are my favourite 👌
In the meantime we will all pretend that living in space will be like living on earth with one "G" gravity and we all just ignorant the fact of that no gravity or reduced gravity does to the human body! Mars is the farthest humans will set foot on and I have doubts that there will be a colony on Mars, let a lone a town or city! NOT GOING TO HAPPEN!!
"If we ever want to get off this planet" . Idiocracy. How about.." If we ever want to survive in the only place we have! " ??
So much Gunna-Do ... and so little means to do it ... Talk is Cheap ... and Wasting $Billions of Dollars ... Robs the people of what we really need ...
Scientism and ideological interests are currently having a coniption fit at a function not comming to call anymore.
They would like to prepurpose literacy with mental and epistemological focality.
For convenience.
It has failed.. but the unease and desperation may be there.
And it may masqurade its cultural relevency.
The truth is we exist at different relatvisms to ourselves now.
Be the integrity otherwise.
Be scientists for us please.
Are you even okay? This is word salad
Just say dollars. The US is understood.
Stop saying "en ee ohs". Just say NEOs.
