Hey Scott! Today was my first day at NASA and, after reflecting on the inspirations that led me here, I want to thank you for being an inspirational character of the aerospace discipline! I started watching you ~8 years ago and, unlike the other youtubers from that time which I watched, you continue to put out super-awesome content! Keep it up!
Well come on then, what was your first day like? What did you get up to? haha
Thats awesome! Looking forward to your Voyager 2, no pressure
Congratulations. So now you are a paid shill.
@@ohasis8331 Spot on.
Congratulations! I know that has to feel amazing to finally be there regardless of whatever position it is.
Minor correction lysis is breakdown. Programmed cell death is apoptosis. Since red blood cells have no DNA nor organelles associated with protein production they're unable to undergo apoptosis. They have to be broken down separately hence lysis. Haemolysis is the breakdown/recycling of red blood cells. This has to be done by cells/organs other than the red blood cells which are not really alive.
So a red blood is just a vehicle and when dead it gets reused?
@@MrHichammohsen1 Effectively. They start out as normalish cells but end up basically empty of all the usual cell bits that make cells alive. They are packed to the brim with a haemoglobin (a protein complex with iron at its core) and have the very specific job of getting oxygen all around the body. Because they are not full living cells they don't last all that long. They have no ability to repair damage so are fully broken down after about 3 months. The body does its best to recycle as much as possible but some parts do end up getting excreted.
@@OneDeuxTriSeiGo And your feces. Bilirubin (or rather stercobilin), one of the breakdown products of heme, the oxygen-carrying molecule, is what gives feces its brown color.

Now we need a spacecraft with a purple burglar alarm.
I'm really glad you shared the Nature Medicine paper. Odette Laneuville, one of the authors of the paper, was one my professors in undergrad. She taught a few of my courses and she would often talk about her work on astronaut blood. I can remember the lecture she announced the project and you could tell she was super proud. She deserves it. Very cool, funny, smart person. I always loved taking her courses and interacting with her.
9:45 I love that description. You bolt stuff to it and figure out it gets very hot when it flies really fast.
Absolutly!!
That made me laugh.
Every extremely technical scientific endeavor needs a liaison to bring the news down to a layperson's level of understanding. Scott accomplishes this with intellect, wisdom and charm. I for one, am grateful.
but he does not understand the stock market so I need to look else where for that information.......
@@generalharness8266 the stock market is actually really easy to understand; it's entirely based on faith and face value.
When you understand the fact that the value of stocks isn't based on anything tangible or quantifiable, it all starts to make sense.
@@thundercactus Yea I get that it was more making a joke. It why a company can fall in value when its product has seen no decline only the shareholders faith has declined.
I strongly think that if you purchase stock you must hold it for x amount of time limiting the amount of manipulation that can go on.
Its pretty much what happened with gamestop.
It's kinda crazy how many new rockets are (hopefully) going to have their debut this year: Starship, SLS, Angara, Vulcan, Ariane 6... What a time to become a space geek!
I'm keeping my fingers thoroughly crossed for most of those, but any one of them would be extremely exciting!
Angara isn't technically debuting
@@E9X330 and tbf It is not that new either, its engines are 40-50 years old. That is why I also not quite interested in SLS.
SLS will never get off the ground 😋
I wish the Energia Buran made a comeback lol
Look Scott, Boca Chica has been around for a while and some sagging is normal and natural during the aging process.
Testicles.
Ha Ha.
I wonder if any habits prevent ur balls from getting super duper saggy when your old 🤔
Having been to boca chica this also applies to most of its residents

An Australian news team couldn't keep a straight face when covering the story of New Shepard's first flight. I'd like to see them reporting on Mechazilla's big balls.
I was going to comment on saggy problem.
Are 'truck nuts' a thing in the US then? Why?!
@@paulhaynes8045 Same as the reason for the giant trucks. The drivers are attempting to compensate for personal shortcomings.
@@adamadamadamadam a common acronym for trucks is an MEV: male enhancement vehicle. How often have I seen an F350 with dual rear wheels and winches on the front and back, parked in the parking lots of software companies...
@@paulhaynes8045 Little known fact, the brains of men in the US dont actually mature past 13 years old. Maybe its the water. 🤷
May have already been said but those large water bags are commonly used to load test and certify large capacity cranes and other types of lifting machines.
Oooh, I was wondering what industry made these exist.
Well duh, testing lifting machines, what the arms are. Now I feel stupid.

Seeing that pressure wave move across the face of the earth really goes to show how mother still rules compared to any nuke or hydrogen bomb that's ever been set off.
I am not saying you're wrong because you aren't, mother nature will always outdo everything we have to offer, but the Tsar Bomba's Shockwave circle the Earth three times, pretty intense.
Mind you something as simple as a hurricane has hundreds of times more energy than one Tsar Bomba
@@sacr3 tsar bomba was 50-58 megatons
The volcano was estimated at 10 megatons
Nature is very powerful, but so is splitting the atom
Of course we can and have built much more powerful weapons than the Tsar bomb, but we've so far been smart enough to not try to test them.
@@UnshavenStatue can we? We can up the yield of a nuke, but even the tsar Bomba isn't worth it, half of the energy from the bomb is lost in the atmosphere.
I don't think we have the capability ATM to create a weapon much larger. Maybe antimatter but that stuff is extremely difficult to make and even more so to contain.
I'm not saying we can't one day, lol what do I know about what's going on behind closed doors
@@sacr3 We certainly have the *capability* to build much more powerful. Even the Tsar bomb itself was only built to half its design energy because of practical concerns, and it's very old tech as far as bombs are concerned. As for practicality/utility, then sure yes there are diminishing gains in a military sense, atmo losses and whatever, such powerful bombs have little purpose, but it is certain that in terms of technological ability, we certainly do have the capability of building stuff that's 10x or 100x more powerful than the Tsar bomb with no problem. Maybe even 1000x or 10000x more powerful. It turns out to be very easy to scale up fusion-fission bombs.
I don't actually remember ever seeing a falcon 9 1st stage seperate like that from ground footage at 0:50, thats crazy.
There was one a while back, but yeah they are rare
i think thats because it went quite vertical and not so horizontal but i could be wrong
Yeah its very cool.
@@bigpod launch profile is one thing, but clouds are the more common obstruction, I think.
And part of why it looked a bit more 'exciting' was it was a return to launch flight, so no reason to coast for a bit and arc down to a recovery vessel, it just wanted to go home! :)
Your videos are awesome. So enthousiastic and informative. Thank you Scott
"Bolt your experiment on and figure out that it gets very hot when it flies very fast."
Is that right out of the Stratolaunch hypersonic testing brochure?
I always enjoy your videos Scott. Thanks for what you do! Fly safe!
Thanks for this great update, Scott, was lagging behind a bit ! Stay healthy !
0:54 That "flip" was amazing 🥵
Since red blood cells come from bone marrow, it seems logical to me that in an atmosphere where there is no weight-bearing being conducted by the bones, it may affect the production process. On earth, our bones are always weight bearing.
Oh that is a good point it could also be because mammals red blood cells are dead i.e. they lack nuclei and other living components basically becoming membranes of hemoglobin. In either case it might be a good idea to see if that happens to a sauropsid (such as a snake lizard turtle bird etc.) as their blood production was not incorporated into their bones like mammals did.
One reason they suggested was because the body tends to lower your total blood volume by a certain percentage when you go into space, the increased intracranial pressure because there's no longer gravity pulling your blood down to your legs causes your body to start to reduce the blood pressure by killing off blood cells, lowering overall blood volume.
The body is making an active effort to remove red blood cells while you are in space, and it continues to remove red blood cells for up to a year after you land on Earth.
The bone marrow continues to produce red blood cells at its regular rate while they are in space, so it isn't so much the bone marrow as much as it is the body removing red blood cells a little faster than it should.
Could really be anything at this point, the body is one hell of a complex machine. My assumption would be that the body knows how to delete red blood cells but does not know how to rid of blood plasma, so in efforts to reduce blood pressure it reduces the amount of red blood cells. Typically a situation on Earth that would only last a short while before the body goes back to homeostasis, whereas in space it's like there is a switch in the head that is constantly being pushed for months and months, screaming to lower the pressure, forcing the body to continuously kill red blood cells for months and months.
I would assume that those beds they are making to assist with lowering the pressure in the head to prevent eye damage, might assist in lowering the amount of red blood cells destroyed by forcing most of the blood into the lower extremities of your body while you sleep.
Maybe we may have to fabricate a pill that will prevent our body from destroying so many red blood cells. Maybe we simply cannot go on Long space trips without a bit of gravity.
@@sacr3 That's a plausible explanation. Solution? Space leeches! 🐛🐛🐛
Would reduce blood volume without hitting red blood cells disproportionately.
What Scott failed to mention in the article is that the red blood cell loss continues even after the return back to Earth
@@TreeLBollingTreeMan it almost reminds me of diabetes, when something that isn't supposed to be used often is used a lot, it may become an issue and become permanent. Our bodies don't generally destroy red blood cells at high rates, it may here and there due to increased blood pressure from whatever you did during that day or week, but to be forced to do so for up to 6 months straight may, for the lack of a better word "break" or alter at a genetic level whatever physiological mechanism is responsible for doing this.
It may become a semi permanent issue or just a very long temporary issue.
I am just throwing hypotheticals out there, the body tends to reinforce mechanisms that are beneficial, like building additional muscle or increasing the strength of bone when both are used and suffer micro damage, so maybe being in an environment that increases intercranial pressure, the body adapts by turning on a switch permanently to try and keep blood volumes low?
Thanks for the great work Scott!
Keep up the good work!!
Love your channel man, thanks for sharing your passion with us!
"From recruiting best of the best to recruiting richest of the richest"
That one cracked me, as my fists clenched
In a handful of years we have gone from, "It's impossible to land a rocket, you are nuts", all the way to, "This is the booster's first flight? So it isn't proven? Do I get a discount?"
Nobody ever said it is impossible to land a booster.
@@HalNordmann wish that was true, stopped watching a youtuber over that
@@lithobreak3812 Maybe some did. But the vast majority of the spaceflight community was thinking it was technically possible, but not necessarily worth it.
@@HalNordmann of course it was always technically possible, what I, and i assume others, mean is that a lot of people firmly said it was impossible to do it in an economic sense
"It's impossible to land a rocket, you are nuts" Apollo 11's LEM rocket landed on the Moon July 24, 1969...
Thanks for doing these videos Scott.
Great report! Thank you Scott!
SOME GREAT IDEAS:
I can't help it, any time when Scott says, "Huuege", I tend to smile & laugh.
Thanks Scott!. It's not a put-down, but just the opposite!
If true, it is extremely fascinating that Yunhai-1 could still be in operation after a major collision event. Either the systems affected were secondary, or excellent redundancy measures were taken during the design phase.
Most likely it was just a solar panel that was hit.
@@dorson723 Because solar panels don't produce thrust.
I knew you would have covered this footage! It was so majestic i can't stop watching it
I love your updates!! Fly safe!! :) :)
18:10 Mentour Pilot has a good video on that volcanic ash plane, very interesting story and definitely worth a watch.
British airway 747 flight 009 and yes mentor pilot has a terrific video on it
I think the “Mayday”/“Air Crash Investigators”* episode about that incident is on RUclips, too. _Fantastic_ airmanship on the part of the crew.
*That show has a different name in I think every different English-speaking part of the world. No clue why they make it so hard to find info about it.
Mentour pilot - excellent vids, but I'm never going to fly again!
I also guess that a lot of people still remember the ash cloud lockdown of almost all European air traffic due to Eyafjallajökull.
@@Tjalve70 Is that how it’s spelled? I thought Icelandic names were harder to pronounce than that… 😆
Scott, I'm an MBA that specialized in corporate finance and I also don't understand the stock market.
It has completely removed itself from real world business and has taken on a life of its own.
Meanwhile I'm an aircraft engineer who, after that career, specialized in the stock market. Such price moves against the latest news are common, and often do make sense given that markets are forward-looking: Prices are at least as much about the consensus for what is expected in the future as about what is presently being announced. Phrases like "The news was already priced in" and "Buy the rumor -- sell the news."
As for Vigin Galactic in particular, "down" has been the rule rather than the exception going back to last summer. It's dropped steadily over that time, and is now about seventy percent below the peak price. I don't follow that company (or any individual company), but from a glance it's a money loser with no great prospects and a lot of competition.
[Edit: As I said, I don't follow individual companies and proved it above when I pontificated as to the "Virgin Galactic" stock price. I now see that their Virgin Orbit spin-off has its own stock, and with a quite different price history. Still sticking to my comments above regarding "market logic" in general, and headwinds against Virgin Orbit in particular.]
Thanks for the updates Scott!
Thank you for another wonderful video, Mr. Manley.
I love the addition of aviation into this with stratolaunch, avgeek at heart
The amount of ice breaking off that Longmarch 2 was insane. It looks like the entire rockets is disintegrating!
I appreciate that you provide links to the original publications.
love these update videos.
8:11 knowing that there is something called trucknuts in texas, was equally amazing to the other news! :D
Some people are ... weird
But he wasn't wrong with that description
well i certainly never expected to see "big balls" in a Scott Manley video title
Great updates! Thank you Scott!
great coverage Scott. Thank you
The mirrors are just moving out of the launch configuration. They move out about one inch. They have not begun mirror alignment yet
There's a peg on the back of each mirror segment that secured them in place, protecting the movement motors on each segment from vibration and G-forces during launch. The first motor movement commands slowly pull the pegs out of their supports by about 12mm or so to free up the mirror segments so they can subsequently be aligned. The JWST people at Goddard have already confirmed that all motors on all segments are functional.
12:38 - How does the alignment laser setup work - e.g. where is the laser mounted - I initially imagined a laser as used for adaptive optics in terrestrial telescopes - which obviously makes no sense in a vacuum.
As I understand they will point Webb to some very bright and pointy objects (isolated stars with a dark background) and move the mirrors until they have a single sharp point in the sensors
I love these updates. All the interesting news without having to trawl through the news and put up with the garbage that that entails. Cheers, Scott!
Awsome content! Appreciate it🙏💚
The water bags are (as someone else posted a few days ago) test articles. Of course.
Excellent animation at 17:46. Really shows how global this event was.
It wasn't animated.

yet another stellar show, thanks Scott..
That pressure wave from the volcano travelling across the globe gives you an idea of how much power was released by that eruption.
I think someone fibbed to you about the Exploration Park Blue Origin factory having to close down during the Transporter-3 booster's landing. It's simply not anywhere near close enough to Landing Zone 1 to merit that. If anyone from Blue Origin had to take the time off, it would be the workers at LC-36 and LC-11 which is very close by and can be seen in video from time-to-time when the Falcon 9 boosters do an RTLS landing.
Man something is! Let’s see the EPA has a study on impacts to environment, now it’s the wildlife that can hold things up. Authorities need to look into both of those departments personnel for large deposits into their accounts. See if there’s a link to all things associated with the hold. Bezzies probably needing it all!
The only reason for the Exploration Park Blue Origin Factory to close during a Falcon 9 booster landing at Landing Zone 1 would be if everyone wanted to see a real rocket land - not just a computer animation.
The factory is 13 km from LZ1. I agree that work at some of the nearby launch pads (or former launch pads) would need to pause since they are about 1/10th that distance.
Actually, that Falcon 9 exploding several years ago on the pad at LC-40 very nearly prevented the OSIRIS REX mission from launching with all the damage it did to the water and other service lines that are shared between it and LC-41.
Scott is one of my favourite Scotsmen. Excellent presentation making the complex understandable for all.
Thank you mr. Manly as always
The long dark from Hinterland. I played the Hardcore Mode for years and loved every second of it, love Timberwolf Mountain lake region and the no so Pleasant Valley ;).
Cheers from Switzerland
A lot of stocks work on the old adage "buy the rumor, sell the news"
The 15:10 Artemis plan seem to suggest the landing will not be before 2027 when the lander will be ready. The years 2026 and 2027 have not been numbered in the published version but the lines dividing them are still there.
unfortunate but seems about right
Thanks as always Scott!
7:21 Thats a really good Jeff Goldblum impression
Spaceships and Giant Island Explosion updates!
Great video! Sad to see that JWST is having problems with its sensors, hopeful everything else works correctly.
The last two mirrors are now in position
I'm glad you mentioned the "resemblance" of the SpaceX ballast. Nobody else covering it has, but I could think of nothing else when I saw the photo...
You're a national treasure, Scott. It takes me about a month to put together the presentations you give us multiple times a week. I don't know how you do it! Fly safe. :-)
ah yes, "Crane and Balls Testing", or CBT.
I just hope the balls don't burst while they do that.
damn L-platers
I will speculate on why the Virgin Orbit stock dropped after the successful flight. I figure when investors see a fake rocket their mind is filled with vague ideas while seeing the actual launch of a small rocket activates the critical thinking that says this might not be a good business model.
monkey's neuron activation moment
Another great Scott Manley video!!
Nice to see you again Scott. Missed you. Keep the dirty side down. Great job.
One of the things that's amazed me most about the Tonga volcano is how fast the loons came up with a conspiracy theory. The best one I've heard so is that the volcano erupted, but the giant explosion seen from space was actually caused by an American SSBN getting caught in the blast and denotating. That's why no communications, you see, EMP. You have to hand it to loons, they are quite creative.
Don't give them oxygen by spreading their loony ideas. They'll soon get bored and go away
@@paulveitch Nah. I find it amusing. I have enough faith in humanity that 99% of people are laughing at them.
@@brick6347 1% is a worryingly large number of people though ...
They should write books and stay off the internet. Would make the world a lot better.
So we need to ask the loonies if a SLBM can produce the equivalent of a VEI 5 volcanic explosion (which equals to that of Mt. St. Helens in 1980).
6:10 More stuff to add to reasons for counter-debris vehicles
This is a little off topic Scott, but your jumper made me remember to finally try The Long Dark. What a game.
Thanks Scott!!
With that many satellites being launched and even more projected in the future is space junk really gonna be a huge problem ?
deorbit everything before it starts to disintegrate
That depends as long as these sattelites are being deorbitted after they are done it shouldnt be a problem unless ofc it gets hit
The problem with space junk isn't the satellites themselves.
As long as all low orbit satellites are properly deorbited when they're finished, that shouldn't be a problem.
The problem is the huge cloud of junk that appears when satellites ARE hit with space junk.
Flying into ash clouds might be a neat use-case for electric airplanes!
Because they'd have the same range? Lol
Good thinking.
I don't think anything like volcanic ash.. That stuff is abrasive, we've been using it to clean toilets and sinks for decades!
Or a piston engine aeroplane with a big intake filter. Like those old warbirds that fought in north Africa in WW2.
Excellent update!
Scott, I'm a scientist and aircraft maintenance director myself. I appreciate your very realistic appraisals. Hats off to your simple expressions filled with integrity!
PS... I lived through 10 months of Mt Pinatubo in 1991. Yes, Volcanic ash with 40% acid content will definitely trash jet engines.
When it comes to the Tongan volcano eruption; Flying in personnel is dangerous to Tonga. It has never had a case of COVID 19. Rare indeed.
Still, 60% of their population is fully vaccinated. And with the less deadly omicron going around, it shouldn't be THAT bad.
Also, New Zealand has very little covid. So I guess the infection risk coming from NZ should not be too bad.
I imagine at the very least you can airdrop basic humanitarian supplies and some statelite coms gear.
Besides some personel like those aboard navy warships are also probably just as covid free as Tonga is. I assume the US Navy redirected the closest carrier group as humanitarian aid is part of their job, to say nothing of the nations much closer to Tonga like Australia and New Zealand. (Both of whom are already working in dispatching aid ships)
I really don't think a virus in which you have a 99.8% chance of survival, is their main concern right now.
Your concern is probably justified. Tonga has the highest incidence of diabetes per capita in the world, and like many other Pacific islands, a big problem with obesity. Both these factors would tend to make the pandemic more dangerous to Tongans, if or when it arrives.
@@ianstobie again, 99% chance of survival, what is it 60 to 70% of Americans are overweight? We can clearly see that this virus isn't all that lethal against individuals whether they be big or small.
It's only those that are immunocompromised, already sick, or are weak or susceptible that die from this virus. My stepmother's uncle passed away from lung cancer, but because he tested positive for covid they labeled it as a covid death.
He died from lung cancer not covid.
When all you pay attention to are the death rates and hospitalization rates on the media, you start to believe that this virus is a lot more dangerous than it really is. Especially in comparison to a lot of other things that are killing us a lot faster.
Dam that sucks about the blood though its good that it works as a way to create amnemia so they can test treatments better I suppose
Gradually the realisation is sinking in that we don't survive well in zero G. We evolved in 1G, after all - why would we expect to be able to live in no G, or possibly even low G? Unless we can come up with 'artificial gravity' that's better than living inside a big rotating can (with all the problems of coriolis), we ain't going nowhere. And, even if we do, we won't be staying there for long.
@@paulhaynes8045 Hey nothing wrong with a rotating can, as long as you keep to the diameter above 100m it's believed you wouldn't get enough difference between your head and feet to produce any problems.
@@harmonyspaceagency1743 the key words there are "100m' (ie enormous) and 'believed' (ie not known). We get dizzy if we stand up suddenly in 1G - just how big does the rotating can have to be before coriolis does not have a debilitating effect? My guess is a hell of a lot bigger than 100m.
@@paulhaynes8045 100m isn't that big, even if its 300m its doable, though not with a rotating can
@@paulhaynes8045 That's the problem. We can only guess. We need testing and hard data.
Thanks Scott!
Coolest opening sound effects ! It sounds like the Manly rocket is propelled by popping soap bubbles! Love it.
Ok so I'm a private pilot. I've been around airplanes since 1980 when I joined the USAF.
I saw, well I remember some Mercury flights, and saw all of the moon shots. I was just thinking how far we humans have gone to making orbital flights fairly simple. I'm watching the movie "6 Million Dollar Man" the series pilot. Steve Auston was a pilot (a hot dog) of an experimental lifting body sub-orbital aircraft. So the "Six Million Dollar Man" got me to thinking about space flight, and how routine it has become.
Didn't he have a blowout in vapor 3?
10th landing? Crazy, that's real reusability
Since you posted that comment SpaceX has landed a fourth booster for the 10th time.
@@KnightRanger38 my god, maybe I'm not an optimist, maybe I'm just a realist
The Space Shuttle landed 133 times with 4 orbiters at any given time. THAT is real reusability.
thank you so much for doing this... !!
You had me at truck nuts. 😂🤣🤣🤣🤣🤣🤣🤣 I'm dying here. Thanks for the laughs
Just a public service announcement, I've been watching and learning from your channel so much that I can no longer sit down and watch a movie like Armageddon without my whole body cringing, PS just a note to others out there this very informative channel will ruin a lot of movies both past and future for you.
You better not watch Dr Becky then.
Atleast it reinforces how good The Expanse is, atleast for the parts not clearly presented as beyond our current tech level.
But yeah a bunch of Hollywood stuff just hurts when you know how things actually work.
see I can still enjoy it because I generally just love disaster movies. I know they run on BS science and that makes them all the more fun, Would be a boring movie if they sent a probe to fly next to the asteroid and slowly pull it off course or run into it two years in advance.
"this very informative channel will ruin a lot of movies" Well, except for "Gravity", of course. That opus was practically a documentary. Most people didn't realize, for example, that when a tether goes taut in space, it just stays that way until it breaks (after a long speech).
I like how NASA is open with their information. They're pretty good at making things public. I wish the "health" bureaucracies were as open and public.
NASA is the only good agency your country has, change my mind.
What a way to finish off my Bday. Thanks Scott 😊
„postage stamp low resolution image quality“ - hilarious! Scott never disappoints!
Just wondering, if spacex could increase launch cadence at KSC to shut BO down until they go outta business 🤔🙃 or at least for a few weeks after Jeff files a new lawsuit or protest. BO might not notice, though, as they aren’t doing much anyway.
I’d cheer BO for success if Jeff wasn’t a sh$t with obstructing spacex instead of building New Glenn.
That HLS lawsuit isn't nothing weird. Whenever there is a big contract, the ones that didn't get it will usually doubt the results. Even SpaceX did it once.
very shocked learning they launched knowing the telescope had issues (broken) i cannot imagine why the couldn't wait and repair the faults. i know they say they have a work around, but it's nuts to think there was a meeting where someone said, it's broken, and someone replied, don't care, get a work around, we're launching, if i was the tin foil hat wearing type i'd be like, wait a minute, what is it that they need to get the thing in space for so fast that they'd launch knowing it's broken but can use a work around to do. it's all a bit mad ted o.0
It might be that the process of fixing this would make it likely that something else would break as well. And if the problem is so minor that they can easily work around it, with no real risk of risking the telescope as a whole, then I can clearly see them going for that option.
When you look at how many delays they had, and this new problem might have cost them many more months, I can understand why they launched if there was a work around. I don't think the motors are broken and can't be used, it's more the sensors on them are the problem, they're probably used to measure exactly how much they have moved each mirror segment. If the work around is to use the laser or some other system to get the readings instead, then it's not really a major issue.
Worst case scenario, those two mirrors cant be aligned, so they are pointed away from the focal point, and JWST loses 11% of its light-gathering.
Lmao @ "so fast". Do you realize how long this has taken?
Thank you so much Scott once again I look forward to every one of your videos or podcast or whatever they’re called I’m just no guy retired aerospace worker I was one of the little guys I fix the machines that broke while making the really big machines. Thanks again
Had me LOLing at the truck nuts comment!
The Truck Nuts slide was a good payoff for the Big Balls teaser. I like what you do. Great channel
Never even knew truck nuts was a thing. Wow 😂
Thanks Scott.
I'm loving Anand's tweet at @17:14. Thought you could slip it past us huh? 😂
TFS Scott, hope the islanders are safe! GB :)
This Moment In SpaceX History

Wait, I don't remember to have seen this part of the flight from the ground, that's amazing!
Lang May Yer Lum Reek! . . . . Oh, and AWESOME once again ; )
