Great vid Fraser. I especially liked your comments on the (failed) meteor shower and more generally about astronomers 'predictions' in space, Aurora was a great example. 👍
Thanks Fraser. I love this format. Nowadays I barely have time to exist so even if I would love to read the actual articles I rarely do but this is great because I can listen/watch while I eat.
@@frasercain Np! I really like the mix of topics you present as well as the realistic viewpoint you bring to some of the more outlandish ideas floating around out there. Question: Would the Solar Sail Ship in Ep5 of Star Trek Strange New Worlds even move? It appears they are using a light source from the ship itself projected against the sail... This seems almost like the problem with the EmDrive to me
I have to say Fraser, even though the "storm of the century" never really materialized, I'm not at all disappointed with the show I saw! I live in a rural area of north central Texas, apparently just far enough away from any major light pollution that I could see the faint meteors from this shower pretty well. From 10pm CST Monday night to 1am CST Tuesday morning, so 3 hours, I saw more than 40 of the brighter streaks from the shower! I even got to see a couple fireballs, one I was lucky enough to be looking right at when it happened and I got to see it fragment. It was amazing :) Just for reference for my level of light pollution, you can see the milky way where I live with the naked eye. It's kinda faint but it's definitely there. On a really clear night with a new moon it's pretty bright and noticeable.
I've heard that a lot of people didn't see many meteors, but they did see the kinds of fireballs that you only see a few times in your life. I've never seen a fragmenting fireball, and I've spend a lot of time outside.
@@frasercain I live in Scotland so you can never count on the weather, I seen it snow a few hours after a cloudless 18c afternoon lol, you did pre warn us that we might not get the show we were after.
Yeah the May 30th event was a dud, but when you see something extraordinary it’s worth it. I once saw a meteor split a low cloud in two, that was worth it.
I would think that their first image would be an ultra deep field, considering one of the telescopes main goals is to look as far back in time as possible to the earliest proto galaxies and discover how they formed. Although, if I were on the JWST team, I'd be very curious to take a look at Proxima B and discover whether or not our closest exo-planet could have the ingredients for life.
I thought starting with the "Webb Extreme Deep Field" would be amazing, it was my first thought too. Unfortunately, it's true that doing that is a very time intensive process that is comparatively kind of low on the science per hour. So as cool as it would be, there are probably a lot of other things you could look at to get a lot of great data in much less time right now. Still, we damn well better see one some day and I'm betting we will.
@@cosmoscarl4332 All the more reason to image it with JWST in aid of calibration, and to see if other, fainter nascent stars are lurking in there. Plus it's very photogenic. The odds are very slim that the first science imaging is going to be just one thing that takes weeks - that's the time-scale involved.
There are a lot of new materials and technologies that they want to incorporate, but they've also requested the new spacesuits be more lightweight and modular. By putting out contracts to multiple providers they're encouraging competition, similar to Crew Dragon vs Starliner.
Frasier, here's what I don't get about the spacesuit issue: why do they have to be redesigned from the ground up as if spacesuits are a brand new idea and nobody has ever built one, or worn one before. Same thing with rockets. Every company that wants to put something in space has to reinvent the rocket. How come that only happens with space stuff? I never hear about car manufacturers having to reinvent the internal combustion engine every time they put out a new model.
There are a lot of new technologies and materials that have been developed over the last 50 years. It makes sense to incorporate those into the spacesuits and not just rely on old designs. So it's about iteration. Other industries do that like crazy, and that example you gave of car companies makes that point perfectly. The modern gas car is an engineering feat compared to cars 50 years ago.
@@frasercain Ok but at least as far as the spacesuits go, wouldn't it be a better idea to crank out a few of the older, proven designs, while they undergo the apparently laborious task of making a new one? I mean, 50 years ago they came out with a suit that could keep people alive on the moon for days.
@@frasercain Tell me about it... It's been raining here since the meteor shower. And it's getting really cold! 😬 (I'm from Brazil, it's autumn here now!)
I saw 10 meteors that night, 2 were pretty spectacular. Almost all were between 830 and 930. None after 10. Thanks for letting us know Fraser, was well worth the chance.
Wow, I was under the impression NASA, regularly upgraded the space suits as a standard operations. Why did they wait to upgrade them as soon as water was building up in the suits while in space? And they say safety comes first. . .PFFT!
I think it was Dr Becky said that even the 1st star it aimed at to do the 1st stage of mirror alignment was too bright when all the mirrors were fully aligned.
Hi Fraser, I am a fan, and I always want to see you. I might quibble about the changing background behind you. It can distract me. I like when the images fade in during the segment, and fade out slowly. When they pan through, I find myself looking at them instead of you. That has its advantages -;), but I might miss what you're saying.
Key word, desperation. It's pretty obvious to me that we can't possibly be "alone" in the universe, even though we may as well be because of the low probability of a civilization anywhere near us. I'm going to continue to believe that that is what you really mean, or believe. I believe that your stance is partially based on trying to get people to appreciate the rarity of life, and a planet like ours, and how it would be a real shame for it not to be preserved. Good on ya!
You should listen to the interview then if you want to hear my chain of reasoning from beginning to end. But I agree that we need to take care of Earth.
A movie that still surprises me how accurate it is about a possible mission to Mars, it the "Red Planet" (2000) with Val Kilmer. Using a bigger modular Spaceship assembled at LEO, then landing on the surface with a smaller lander.
If NASA is renting space suits, does that mean a market exists for used spacesuits? Talk about the ultimate man cave décor! and an awesome she-shed essential.
I get Fallout power armor vibes from the new spacesuits. It's uncanny once you see it haha! This is the first time I've watched your videos, I love your format!
Thanks Frazer, my relatives are co-inhabitants of your island - I don't know where else to suggest this, but I would like to propose Ms. Heard for a place on the Dear Moon crew, a free one of course.
7:54 I believe this is a misstatement - the Voyager probes are _losing_ approximately 4 watts of power generation per year, i.e. “down four watts” per year, not “down TO four watts”. I can’t find any figures on what their current actual power generation, but considering the teams are trying their best to keep them going beyond 2025, it seems very unlikely they’re actually at 4W.
@@frasercain I think a consensus will be difficult, but hope those who secretly wish it might help SETI research prevail over those who mostly want a dramatic picture.
@@frasercain I know it doesn’t make a standard color photo. But from everything I’ve read, it isn’t capable of seeing anything other than infra-red. These questions have been asked, and the answer was that we won’t get photos like the Hubble takes because the range isn’t there. Remember that gold reflectors are optimized for infra-red, not visible light. I haven’t read anything about the detectors being able to see beyond that. And if they don’t, filters have nothing to filter.
It'll be different wavelengths of light, but they'll still be combined into full color images. Many of the images from Hubble aren't in visible light either. They're often taken using filters that only show hydrogen, oxygen and sulfur. But three filters showing three different wavelengths of light can be combined to make a full color image. JWST's pictures will look like Spitzer images: www.nasa.gov/multimedia/imagegallery/image_feature_476.html
@@melgross The NIRCam instrument is sensitive to the near-IR range. The instrument has a series of filters that divide this range into 6 slices. To take a color image, you'd take exposures using 2 or more of these filters, then assign a color to each exposure.
Sure, but it gives an interesting target to search for. We should also be searching for rogue planets anyway, since they'll almost certainly be closer to us that the nearest star.
I think this is a smart way to go about it. Purchase spacesuits from commercial providers instead of building themselves. I'd think you'd prefer a free market approach here, but maybe not?
@@frasercain I JUST saw Marcus' video on it. The renders of Collins Aerospace for those new spacesuits are AMAZING! NASA's own xEMU design looked more like a scuba diver's suit from the early XX century, lol But those did provide the blueprints for both private companies it seems, so it's all good!
Exactly. I think they're figuring out the right mix of NASA-built and commercial suppliers. And when they do go with commercial suppliers they bring on multiple companies so there's competition in the system. I honestly think that commercial crew is a stroke of genius and it demonstrates how SLS just doesn't cut it in comparison.
@@frasercain Yeah, my original comment was in relation to how NASA always kept making announcements for ''new'' spacesuits every other year, I feel like I've seen dozens of those lol But now, with private companies actually getting involved for real, there's a good chance things move past the rendering stage, for a change I think we owe Elon for opening up NASA to the idea of working with private companies.
I think it'll be a picture of something recognizable, like a famous nebula or something. JWST won't be able to search for Planet 9, but if someone finds it, it'll be able to scan it and provide more information.
I always listen to you and think "he sounds like someone else... who is it?". It took me years to realize, and it just came to me... You sound like Ryan Reynolds!
@@frasercain That explains a lot, but it's more than that. I believe you also have the same voice timbre. Anyway, thank you for answering. I'm a fan of your work for quite some time. I know it's not necessarily space related, but If you ever need someone to talk about neutrinos and neutrino detectors, let me know.
Alright, Fraser! If you're going to tease Universe Today interviews, I demand one featuring Matt Williams in which we finally learn the answer to the deepest and most important question that's been stumping humanity's greatest minds for the past decade: Why does Matt insist -- in this age of technology -- on utilizing a PC that's ostensibly incapable of running spell-check software while he's composing his articles? We, the people, deserve to finally know the truth! :-)
Hah, I've given Matt a Grammarly account, so he should have improved quite a bit, but I'll double check his work a little more carefully. He does make his share of typos. I'll be sure to bring it up in our interview.
Can anyone answer a question if they know. The JWST seems to be locked into position on the heat shield. Is that right? If it does not swivel or rotate then large areas of the sky are not accessible at any given time. So does it rotate or swivel at all?
@Tom's Cubes Haha, we have similar thought processes, if it does not pivot or rotate then firing rockets would be needed almost constantly wouldn't it? Even if it did rotate then the rockets would be needed to keep it pointing where you want it.... I have no idea really.
It can rotate and swivel, but not a lot. It can observe targets between 85° and 135° off the Sun line. It also has to wait for its orbit around the Sun to allow it to see different objects. It has flywheels like Hubble to orient itself at different targets.
It uses reaction wheels like Hubble, but then it has a totally different technology to keep itself trained on a target. We did a video about this: th-cam.com/video/mvVgGh7uiEg/w-d-xo.html
I guess the meteor storm event was a no show huh? Unless it happened at a different time than estimated, i didn't see more than about 20 streaks and some may have been fireflies lol
I'm ready to see some full color 10 billion dollor images of some habitated exoplanets with civilization bearing technosignitures. Maybe a closeup of apophis or even a closeup of ancient megaliths on the moon or better yet a closeup of omuhamua
JWST will be able to image exoplanets as a single pixel. We're going to determine if there's life on those planets by doing spectroscopy on that light, i.e. looking for elements and compounds in the atmosphere of those planets that don't occur without life, e.g. oxygen.
Seen the Northern lights one time half the dark sky was light up to do a half circle swirl spinning vortex looking thing looking straight up over head^ Never seen one again!
In 2018 JAXA launched a 2½ tonne 10m rocket which put a 4kg 3U cubesat into orbit. That's the smallest successful orbital launch yet. I assume you could go a bit smaller and lighter to launch keys or socks, but probably not by much.
Ah ok so if car keys weigh 100g I can assume the rocket can be 40 times lighter than JAXA because the keys are 40 times lighter than the cubesat . Got it, thanks.
N.A.S.A. is going to be waiting for new space suits. Like all government contracts there will be on going delays for the need of larger bonus checks for the winning companies upper echelon management's bonus checks. They know how to build them, been doing it forever, that can be and has been said for another legacy company, how far behind and over budget are they ?. Honestly, N.A.S.A. never learns.
I think they learned a lesson from Crew Dragon, going with competing commercial providers. NASA is learning, and they're seeing benefits from these new strategies.
Voyager reached the edge of the zoo eh. Any updates on this would be appreciated. We've trusted it this long. Would be weird to just throw away valuable info because it doesn't meet what we expect.
17:42 Yo Fraser. Uranus, despite being closer to the Sun is actually colder than Neptune. Can you please explain what you mean here? Are we looking at some sort of evaporative effect that explains this discrepancy and temperature variation?
Good catch, sorry, yeah, Uranus can get colder than Neptune because it's tipped over on its side. The side facing away from the Sun can be in total shadow for a long time, while Neptune still has regular day night cycles. So on average, Neptune is colder.
Question, is there dust in space? Will a spacecraft like the ISS or a satellite get dusty and weathered over time, like in Star Wars or is more Startrek?
In low Earth orbit, you can expect regular impacts from man-made space debris. Most of this is tiny: flecks of paint, etc. This won't settle on the surface and make it look weathered: it'll impact at several km/s and punch through the surface. Once you're out of Earth orbit, things are much cleaner. JWST won't encounter more than micrograms of dust per year.
@@frasercain wow thanks for your time and reply. The book is more of an anthology and plays in several chapters, and still science fiction at its best. The wandering earth is still a great story inside that. A bit confusing maybe, if someone expects a story from beginning to the end. I could imagine that you could draw some inspiration for your channel out of this. He has a very unique view on socio-political effects of such an event. It’s really worthwhile. Of course Trisolaris Saga is his masterpiece. I wish I could read all of his work in Chinese. Greetings from Germany.
12:35 Remember that it may take "1000's of years" from the perspective of those still on Earth, but far less time for those on the spaceship (time dilation/spatial contraction). This is assuming a probably technologically unreachable speed near that of light.
I'm fully emotionally prepared to say goodbye to the Voyager probes. I'm not so sure if I'm prepared for one of them coming back to earth in a really terrible Star Trek movie though.
The heliosphere? Is that what they call the plasma membrane encompassing our system? Did the voyager make it all the way thru? Could that be garbling our comms?
No. The science data is still coming through intact. Only the data from the attitude control system is corrupt. That makes it likely there's a problem in the AACS.
QUESTION: So not too long ago, NASA debuted "new Artemus Space Suits" and now it seems these are to be left in the dust and instead some people will start over and develop new suits... did I get that right? or is at least one of these two companies responsible for the suits we saw demonstrated? Certainly the announcement seemed to indicate these companies were welcome to design from the ground up, to use the same design for both space work and surface work or not as they chose. I wonder if it would be legal to buy Chinese station suits "off the rack". China has indicated, I don't know how close to the truth this is, a willingness to share their space station and has in the past been willing to sell pretty much anything.
I could be wrong about this so take it with a grain of salt, but I believe the reason they have to redesign them is because the suits they designed were based on the current suit designs, which are currently having problems with water getting in the helmets like the video points out. I don’t know how accurate that is but regardless SpaceX has already said that they can design the suits if they have no other choice.
The Chinese are willing to let other people join their space station and have signed up several countries for future collaboration. Because of a security restriction, the US won't allow any Chinese collaboration, which is a shame in my opinion. NASA passed over all the designs of spacesuits they'd developed to their partners who will deliver them working space suits. It's similar to them paying for flights with SpaceX and Boeing. It seems like a pretty good strategy, that allows NASA to focus on other challenges.
Fantastic episode! Thank you, Frasier. About the new space suits, there's only ONE requirement- Do They Look Cool? That's THE most important thing 😉
That really should be a primary requirement.

Although, if I were on the JWST team, I'd be very curious to take a look at Proxima B and discover whether or not our closest exo-planet could have the ingredients for life.
A deep field image can't be produced quickly - it takes many hours/days of exposure time. I'm betting on something like the Pillars of Creation.

They're up on the space station, so they need to bring them back down and make repairs and upgrades. They're like little spaceships.
Besides the sun (and anything sunward) are there any other targets JWST cannot look at? For example, is Jupiter or Sirius too bright?

And if they don’t, filters have nothing to filter.
It'll be different wavelengths of light, but they'll still be combined into full color images. Many of the images from Hubble aren't in visible light either. They're often taken using filters that only show hydrogen, oxygen and sulfur. But three filters showing three different wavelengths of light can be combined to make a full color image. JWST's pictures will look like Spitzer images: www.nasa.gov/multimedia/imagegallery/image_feature_476.html
@@melgross The NIRCam instrument is sensitive to the near-IR range. The instrument has a series of filters that divide this range into 6 slices. To take a color image, you'd take exposures using 2 or more of these filters, then assign a color to each exposure.
July 12th! whahoooo! 🤠🚀
Set your calendar.
The idea of using a rogue planet as spaceship is simply preposterous
Sure, but it gives an interesting target to search for. We should also be searching for rogue planets anyway, since they'll almost certainly be closer to us that the nearest star.
Right. In the calendar.
Excellent, now we'll just count the days. 40 more sleeps.
why not do a video about all the existing and upcoming technology that goes into spacesuits 😉
Great suggestion. Or at least interview someone about them.
So image release is delayed. They said June originally.
I'm not sure NASA ever gave us an official date, just a rough estimate for 6 months after launch.
NASA's "new" spacesuits
Getting ready since1972, lol
I think this is a smart way to go about it. Purchase spacesuits from commercial providers instead of building themselves. I'd think you'd prefer a free market approach here, but maybe not?
@@frasercain I JUST saw Marcus' video on it. The renders of Collins Aerospace for those new spacesuits are AMAZING! NASA's own xEMU design looked more like a scuba diver's suit from the early XX century, lol
But those did provide the blueprints for both private companies it seems, so it's all good!
Exactly. I think they're figuring out the right mix of NASA-built and commercial suppliers. And when they do go with commercial suppliers they bring on multiple companies so there's competition in the system. I honestly think that commercial crew is a stroke of genius and it demonstrates how SLS just doesn't cut it in comparison.
@@frasercain Yeah, my original comment was in relation to how NASA always kept making announcements for ''new'' spacesuits every other year, I feel like I've seen dozens of those lol
But now, with private companies actually getting involved for real, there's a good chance things move past the rendering stage, for a change
I think we owe Elon for opening up NASA to the idea of working with private companies.
In what year do you believe that we will develop the technology to capture both voyager 1 and 2?
I say about 300 years from now so 2322
Neptune and Uranus,solar system's gas station of the future! lol
That would be pretty cool.
If they stop filming their footage underwater the problem would solve on its own 🤣
?? Do you think it will be something we will recognize?? Will they use the jwst to look for the 9th planet??
I think it'll be a picture of something recognizable, like a famous nebula or something. JWST won't be able to search for Planet 9, but if someone finds it, it'll be able to scan it and provide more information.
@@frasercain awesome thank you for the quick response, I love your videos!!
I always listen to you and think "he sounds like someone else... who is it?". It took me years to realize, and it just came to me... You sound like Ryan Reynolds!
Hah, we were born in the same city, so we have the exact same accent.
@@frasercain That explains a lot, but it's more than that. I believe you also have the same voice timbre. Anyway, thank you for answering. I'm a fan of your work for quite some time. I know it's not necessarily space related, but If you ever need someone to talk about neutrinos and neutrino detectors, let me know.
Alright, Fraser! If you're going to tease Universe Today interviews, I demand one featuring Matt Williams in which we finally learn the answer to the deepest and most important question that's been stumping humanity's greatest minds for the past decade: Why does Matt insist -- in this age of technology -- on utilizing a PC that's ostensibly incapable of running spell-check software while he's composing his articles?
We, the people, deserve to finally know the truth! :-)
Hah, I've given Matt a Grammarly account, so he should have improved quite a bit, but I'll double check his work a little more carefully. He does make his share of typos. I'll be sure to bring it up in our interview.
Can anyone answer a question if they know. The JWST seems to be locked into position on the heat shield. Is that right? If it does not swivel or rotate then large areas of the sky are not accessible at any given time.
So does it rotate or swivel at all?
@Tom's Cubes Thanks mate, I will edit it and if he knows and sees it, I might learn something.
@Tom's Cubes Haha, we have similar thought processes, if it does not pivot or rotate then firing rockets would be needed almost constantly wouldn't it? Even if it did rotate then the rockets would be needed to keep it pointing where you want it....
I have no idea really.
It can rotate and swivel, but not a lot. It can observe targets between 85° and 135° off the Sun line. It also has to wait for its orbit around the Sun to allow it to see different objects. It has flywheels like Hubble to orient itself at different targets.
@@frasercain Thanks heaps mate. The service you give your viewers is first rate.
It uses reaction wheels like Hubble, but then it has a totally different technology to keep itself trained on a target. We did a video about this: th-cam.com/video/mvVgGh7uiEg/w-d-xo.html
I wonder if anyone's taking bets on what the image will be of.
Hah, I'd love to see a JWST version of the Hubble Deep Field just to show how powerful it is.
@@frasercain YES! That would be my first guess too. 2nd would be the pillars of life.
I guess the meteor storm event was a no show huh? Unless it happened at a different time than estimated, i didn't see more than about 20 streaks and some may have been fireflies lol
It was mostly a no-show, but some people did see several once-in-a-lifetime fireballs, so it seemed to have bigger chunks, and less dust.
I'm ready to see some full color 10 billion dollor images of some habitated exoplanets with civilization bearing technosignitures. Maybe a closeup of apophis or even a closeup of ancient megaliths on the moon or better yet a closeup of omuhamua
I'm ready too.
JWST will be able to image exoplanets as a single pixel. We're going to determine if there's life on those planets by doing spectroscopy on that light, i.e. looking for elements and compounds in the atmosphere of those planets that don't occur without life, e.g. oxygen.
@@h.dejong2531 biosignatures, lol I said technosignatures because I getting ahead of myself. I was being facetious.
Seen the Northern lights one time half the dark sky was light up to do a half circle swirl spinning vortex looking thing looking straight up over head^
Never seen one again!
That's amazing, I've only seen it once like that too.
Yes there are stars
Question, how big of a rocket would one need to build to send their car keys or socks to space?
In 2018 JAXA launched a 2½ tonne 10m rocket which put a 4kg 3U cubesat into orbit.
That's the smallest successful orbital launch yet.
I assume you could go a bit smaller and lighter to launch keys or socks, but probably not by much.
They also launched a 300kg 5.2m rocket that got above the Karman line, so technically in space, but not into orbit.
Here's more information on that rocket: global.jaxa.jp/press/2018/04/20180427_guinness.html
Ah ok so if car keys weigh 100g I can assume the rocket can be 40 times lighter than JAXA because the keys are 40 times lighter than the cubesat . Got it, thanks.
N.A.S.A. is going to be waiting for new space suits. Like all government contracts there will be on going delays for the need of larger bonus checks for the winning companies upper echelon management's bonus checks. They know how to build them, been doing it forever, that can be and has been said for another legacy company, how far behind and over budget are they ?. Honestly, N.A.S.A. never learns.
I think they learned a lesson from Crew Dragon, going with competing commercial providers. NASA is learning, and they're seeing benefits from these new strategies.
What's your bet for the Starship flight? Will it make into orbit? Will it explode on reentry?
Exactly what you're saying. I think it'll make it to orbit and explode on re-entry.
@@frasercain That would be awesome.
Voyager reached the edge of the zoo eh. Any updates on this would be appreciated. We've trusted it this long. Would be weird to just throw away valuable info because it doesn't meet what we expect.
They won't throw anything away, but eventually it'll run out of power to run its transmitter to send data home.
I can't see the sky very well at all. I have to drive 60 miles where no light pollution is. I can't afford a car or gas at the moment.
That sucks. :-( Hopefully you can organize a trip with some friends to do some stargazing. Maybe for the Perseids in August.
17:42 Yo Fraser. Uranus, despite being closer to the Sun is actually colder than Neptune. Can you please explain what you mean here? Are we looking at some sort of evaporative effect that explains this discrepancy and temperature variation?
Good catch, sorry, yeah, Uranus can get colder than Neptune because it's tipped over on its side. The side facing away from the Sun can be in total shadow for a long time, while Neptune still has regular day night cycles. So on average, Neptune is colder.
@@frasercain Ahh good to know. Thanks for the response Fraser!
Neptune is about 20 degrees colder, on average.
@@frasercain Right, so on average Neptune is colder but Uranus has the coldest temperature recorded?
Exactly.
by the way, please explain what a Lagrange Point is Fraser. Just Kidding! lolz 🌠
Can't talk... doing pushups.
Question, is there dust in space? Will a spacecraft like the ISS or a satellite get dusty and weathered over time, like in Star Wars or is more Startrek?
There are vast amounts of dust in space and it is the source of a range of technical challenges.
In low Earth orbit, you can expect regular impacts from man-made space debris. Most of this is tiny: flecks of paint, etc. This won't settle on the surface and make it look weathered: it'll impact at several km/s and punch through the surface.
Once you're out of Earth orbit, things are much cleaner. JWST won't encounter more than micrograms of dust per year.
Thank you for mentioning Xixin Liu, although the movie adaptation is very weak in my opinion
I've heard the book isn't that great either, compared to the 3-body problem series.
@@frasercain wow thanks for your time and reply. The book is more of an anthology and plays in several chapters, and still science fiction at its best. The wandering earth is still a great story inside that. A bit confusing maybe, if someone expects a story from beginning to the end. I could imagine that you could draw some inspiration for your channel out of this. He has a very unique view on socio-political effects of such an event. It’s really worthwhile. Of course Trisolaris Saga is his masterpiece. I wish I could read all of his work in Chinese. Greetings from Germany.
Could a galaxy ever escape a DM halo? Or, is a galaxy without Dark Matter just born that way?
I’m assuming it’s going to be a picture of “Deep Field”, just part to of Hubble’s.
That would be cool. Do the same region as Hubble just to show off. :-)
Can't wait
12:35 Remember that it may take "1000's of years" from the perspective of those still on Earth, but far less time for those on the spaceship (time dilation/spatial contraction). This is assuming a probably technologically unreachable speed near that of light.
It would be tricky to get a ship up to a high enough speed to experience that kind of time dilation.
Space suits as a Service? SsaaS
Exactly.
Great... more money for Raytheon.
They build a lot of space hardware.
July 12th
😁
Set your calendar.
I'm fully emotionally prepared to say goodbye to the Voyager probes. I'm not so sure if I'm prepared for one of them coming back to earth in a really terrible Star Trek movie though.
They are photographs not pictures.
Isn't a photograph where light is exposed onto a chemical paper and then developed in a dark room?
The heliosphere? Is that what they call the plasma membrane encompassing our system? Did the voyager make it all the way thru? Could that be garbling our comms?
Oh, interesting idea, but no, it's not thick enough to mess with Voyager's transmissions. It's just that the spacecraft is old.
@@frasercain hey!!!! Yay!! Fraser Cain noticed me!!😁😁😁
No. The science data is still coming through intact. Only the data from the attitude control system is corrupt. That makes it likely there's a problem in the AACS.
What if it gets hit again?
next week, next month, next year...
QUESTION: So not too long ago, NASA debuted "new Artemus Space Suits" and now it seems these are to be left in the dust and instead some people will start over and develop new suits... did I get that right? or is at least one of these two companies responsible for the suits we saw demonstrated? Certainly the announcement seemed to indicate these companies were welcome to design from the ground up, to use the same design for both space work and surface work or not as they chose. I wonder if it would be legal to buy Chinese station suits "off the rack". China has indicated, I don't know how close to the truth this is, a willingness to share their space station and has in the past been willing to sell pretty much anything.
I could be wrong about this so take it with a grain of salt, but I believe the reason they have to redesign them is because the suits they designed were based on the current suit designs, which are currently having problems with water getting in the helmets like the video points out. I don’t know how accurate that is but regardless SpaceX has already said that they can design the suits if they have no other choice.
The Chinese are willing to let other people join their space station and have signed up several countries for future collaboration. Because of a security restriction, the US won't allow any Chinese collaboration, which is a shame in my opinion. NASA passed over all the designs of spacesuits they'd developed to their partners who will deliver them working space suits. It's similar to them paying for flights with SpaceX and Boeing. It seems like a pretty good strategy, that allows NASA to focus on other challenges.
One day "rich" people will be buying asteroids, taking trips to and fro them like private islands... One day
Space 1999!!!🙃
So Uranus is passing gas into the atmosphere and causing a planet wide haze...got it.
