Thanks for taking the time to do a Space Bites while on vacation! Hope you have a blast :)
Having a great time. 😀

You deserve it! Amazing videos. Legend. Thankyou.

DO and say we didn't ---- Good
Don't do and say we did ---- Boring
@@frasercain Are you going to check out some of there AI? And report back the best thing about Japan when you get back?
The fact that the Vera Rubin telescope can resurface the mirror onsite in five hours blows my mind. The thought that went into that concept is astounding. Kudos to all those people involved.
I saw a show aboot the Arecibo Observatory was the start of on site resurfacing. They used aluminum. I'm guessing this an newer process / upgrade from that telescope
Vera comes online in 2015 eh? Those guys work fast!
Hah, 2025
I didn't know if I'd slipped out of a time stream and went back a decade.
BTW you beat me to it.
@@kalrandom7387 lmao, I was checking to see if anyone else caught that :P
I hope they'll be getting paid back-time!
Lol I literally was like "when was this video made?" Oh yeah thought so...😅😅😅😅😂😂😂😂
"Id like to resurface my 8.5 meter telescope mirror please "
"No problem sir we'll have that done for you by lunchtime" 🤯
hahah Right. That would be awesome
"Remember that time when they thought about planet 9" reminds me of "remember that time when they thought Vulcan was a planet inside the orbit of Mercury?" Turned out it was relativity that was causing Mercury's orbit to act weird, but there were solar system maps with a 0th planet for a while, and even people claiming to have made observations. Now we don't talk about it.
The existence of Vulcan was always spockulative.

Mate! Thanks a lot for bringing our space news even though you're on vacation. So much appreciated and not expected. Thanks again, and enjoy Japan!!!
Thanks for all you do Fraser!
The audio makes me feel like I'm wearing a new SpaceX suit.
Thanks for the great content. Have an awesome vacation!
There were a lot of auroras Friday evening, sadly it was too cloudy in my city in Denmark. But others took lots of beautiful photos.
0:12 Fraser,
There has been a lot of discussions online about the Polaris mission EVA spacesuit that explain why they don’t look like the EVA spacesuits used by American and Russian crews on the ISS. Basically, the Polaris spacesuits are more like the spacesuits used in the Gemini missions than modern ones. In other words, all the life support is in the Dragon capsule just like all the life support for the Gemini missions were in the capsule. So, just like Gemini the space walking astronaut will be tethered to the Dragon capsule for the entire space walk.
In addition, like Gemini the Dragon lacks an airlock. (Unlike Gemini it does have a true docking port but that can’t act like the airlocks on the ISS.) So, like Gemini, prior to the spacewalk the entire crew will need to don spacesuits and the whole capsule will be depressurized. Will Robinson-Smith over at Spaceflight Now wrote a really great overview with more details.
@bbartky How F'n awesome it it to be in modern space apparel with a name sounding like Will Robinson-Smith?
I vote for the Vera Rubin Telescope story (formerly known as the Large Synoptic Survey Telescope, or LSST). Now, I once briefly met Clyde Tombaugh, the man who discovered Pluto, after a lecture in 1987 at the Griffith Observatory in LA, so if it exists I have a strong interest in finding the "real" Planet 9. However the scientific value of the Vera Rubin is so enormous that it excites me far more. I've been looking forward to it for years.
It is with a heavy heart that we announce the passing of our dear friend Marty Kunz, affectionately known to all of us as Space Pirate. Safe journey dear friend, as you sail on to higher ground.

As much as I look forward to the day when a trip around the moon could be as accessible and ubiquitous as a flight to another country...I wouldn't want to be one of the human guinea pigs testing out those brand new suits...especially ones developed by the guy who made the Cybertruck.
What makes me so excited for the possibility of a Planet 9 is that if it's there and if it's Earth-size or larger, it will no doubt be geologically active on some level and thus be extremely valuable for science to study. We have an analogue of "what if Earth was a choking hot hellscape" in Venus, this could be the opposite to that; "what if Earth was a dark ice ball." Like the Cryogenian but waaay more extreme. It'll also be exciting for kids and elementary school teachers who will now have a "replacement" for Pluto in their textbooks, and arguably a much more interesting one (no hard feelings Pluto fans.) I'm also curious what it'll be named if it is found. Will it be given a Roman god name as is tradition or will they go with something else? Which entity from mythology would fit best?
Have you ever spoken to someone who bought a cybertruck? They’re pure crap.
I feel you man --- I wonder if those people who bought the TWA ticket to the moon will honor the tickets. If not - talk aboot a TWA CORP slap to the ticket holders face.
Thanks for all the news, Fraser! 😊
Great rant!!!
Stay safe there with your family! 🖖😊
Remember when planet 9 was Planet X? Good times.
Pluto is *still* Planet 9.
The mysterious, missing planet is "Planet X", of course.

Mahalo for taking the time out of your vacay to update us, Fraser! I appreciate your "Ian Lauer" recommendation. He's one of the more humourous astrophotographers out there. I'm also finished watching ALL his videos. Did the same with Swapna Krishna, too. Eminently watchable! Enjoy the heck out of Japan; I certainly did! Aloha 'til next time.
Hope you’re loving Japan!!! Love your channel and the way you talk about science. Full of vim and vigour! I’m so glad I found your channel and thanks for the post while you’re on vacation.
For a person like myself, without even a HS diploma, but who is keenly fascinated with the Sciences; this is perfect. I thank you.
Great news. Thanks for doing this whilst on holiday.
I found it! It's called Pluto and it's actually a binary planet system so, it's really 9 and 10.
lol
Great video Fraser...👍
thanks mate
something nice to watch before i head to work
thank you
Sound sounds fine!
If planet 9 is discovered, I vote we name it Plutarch. That way mom can serve us pizza again
@wellplaid i wanted a subtle nod to Pluto (Even tho the names are actually not telated). But as long as we get pizza, I'm good.
@@wellplaid We already have Poseidon (Neptune).
@@Erevos85 Sticks the flag of Knowledge into the ground and yells
KNOWLEDGE BITCHES hahahaha
Will be named after a roman god.
I guess they could give it the name pluto and change current Pluto's name as it's no longer within convention.
But likely it will be something new.
Strong possibilities: Juno, Minerva, Vulcan, Vesta.
My guess goes to Juno, if the planet does exist, cause it's shepherding the solar system with Jupiter. Juno is Jupiter's wife.
Also cause predictably this would be a planet born between mars and jupiter that was jettisoned out and thrown into the outer solar system... or a capture.
So, Juno is a likely name. Unless we see any sort of distinctive feature that makes a different one more fitting.
Edit: so, i looked this up some more and most names are already taken by other celestial boddies, which is a mess.
So, i have a feeling that planet 9, to exist might spark a reclassification of the naming of celestial bodies, cause it's a real mess atm.
I am afraid that otherwise planet 9 will get a very unfitting name with the rest of the planets.
Congrats Fraser. Even working on vacation: What a space fan!

Welcome to Tokyo! Have fun!
I recently commented, positively, about the Vera C Rubin telescope on Reddit. How it will double the known number of objects in the system. Unfortunately I used the initials “VCR”.
I got so teased.
Better than getting tased.
Cainsan, hope you're having a great time here in Japan! Would love to see you back sometime to give a talk or appearance in the future. Thanks for all you do.
Great video. Thank you.
Thanks Fraser

03:45 The observatory comes on-line in 2015? That should be a BLAST TO THE PAST!
I'm so freaking excited for Vera Rubin
What would go into the testing and quality control of a mass produced space suit? TBH the idea has me a bit concerned. Definitely can't have any defective suits going up.
So cool, have some green tea for us. Hope the trip is great, Japan seems pretty amazing.
Will do. 😀
Also, watch out for Godzilla
@@frasercain Nice vacation flex - wasn't a suttle 1 -- we all saw it lOl
TFINER didn't pass into NIAC phase 2 :(
that was probably the coolest concept on the list - "solar sail" except out of plutonium, so it can work anywhere
better luck next time, probably
but this idea deserves to be remembered
I WISH Vera Rubin came online in 2015!
Fraser, what are your thoughts on K2-18 b? P(Life)?
Love your channel. Enjoy your vacation, and thanks for all the great content.
I wish science wasn't so contentious. It seems to go through these phases, and you would think they'd learn, but scientists still do it today. Someone comes up with a new theory, and the other scientists dont agree and laufh, make fun, and ridicule. Then when it's proven correct they all jump on board yes, yes we knew that.
I've really been enjoying your presentations. Thank you for taking all of the time and putting in all of the effort required. I hope you do save time for yourself and your family to enjoy Japan (and, who knows, engage some Japanese astrophysicists and space scientists, astronomers and the like--I would love to hear more about their efforts).
Man, hands down best science/space communicator on this ball of rock and water! Hope this comment helps your personal algorithm as well, you deserve it.

The SpaceX helmet looks snazzy, but I’m sure that neck is locked so it restricts vision a lot more than the motorbike helmet it resembles. I wonder why we went away from the good old fishbowl design.
I live in Japan since 2 years! Hope you’re having a great vacation here :)

The RTGs That were used by NASA in their satellites and spacecraft used to be installed at a facility at 10 minutes. Walk from my house. The place was called The Mound. It was an armory during the Civil War, a civil defense plant during World War II and a research facility during the Cold War. The NASA spacecraft would be brought into my little town with no publicity and probably in the middle of the night. Two months before NASA launched a spacecraft to Saturn. At 4 AM one morning I saw a gleaming white semi tractor/trailer with no markings come down the hill from The Mound. Both my car and the truck we’re headed toward interstate 75. I had no doubt that the rig would be headed south on the interstate toward Florida. And two months later, the space probe started on its journey did the giant.
A question I have about space suits being used on the moon or other solid surfaces that would be dirty like our moon is how do you clean the suits before getting back inside living areas ? A water with soap wash system would work with recovery of the water to be used over again ....
Water? Much too expensive!!
Moondust is electrostatically charged: clean by electrictrik.
I remember you had a trip to Japan planned shortly before the pandemic. Why do I remember such things, but return from the store without milk? Glad you finally made it, hope you're having an awesome time!
Yep, we had to cancel it because of the pandemic. Now we're back!
QUESTON - hi Fraser, I have a question about cosmology, specifically inflation theory. This is a simple question probably I'm sure everyone asks it eventually. Question, - isn't it possible that time and space were decoupled in the very early universe? Inflation theory is about the very early universe growing exponentially, faster than the speed of light. It seems impossible or difficult to understand how that can happen because of how we understand spacetime today. What if the inflation of space grew at a "normal" pace except that it was time that was running too slowly basically halted at that point. The early universe could be expanding at some conceivably understandable rate except time was frozen or hasn't started yet or was decoupled from space. Space with no time? It seems like a crazy idea but also space and time are the same thing combined as spacetime - except, unless if they were decoupled in the beginning(?) Time could have gone through a kind of phase change just like all the other stages in the origin of the universe. Time is "emergent" some say. Spacetime is combined space and time. In a black hole, possible weird things happen to time... as well as space. Seems like a simple logical leap to question time in the very early few moments of the universe. I don't know but inflation theory doesn't seem to be explained well in detail - shrugs, scratches head. Thanks!
Hey everyone, mutable CMEs are going to hit eath later today early tomorrow. Check outside tonight to see if you can see the northern lights. Also, unplug any computers from the power outlet just in case.
Could you please get the hotel staff to straighten up that ceiling light? It's not level.
The talk about the scientific process was a good idea. It's easy to get impatient when you're in the middle of that process, but remember that many concepts we take for granted had to go through the same steps. Two hundred years ago, lifeforms couldn't go extinct, the continents were fixed in place, and disease was caused by poisonous vapor in the air. Then decades of scientific discovery and debate played themselves out and put us where we are today.
Exactly. :)
That suit looks cool
Exciting!❤
Well deserved and quite postponed trip Fraser. I remember you did want to go to Japan before the plague.
Yup, we're making up for lost time

Welcome to Tokyo
Japan! Nice! Have a nice trip! 🍻
I know that this makes me sound ignorant but my problem with planet 9 is that I thought we had the gravitational math nailed down. We found Neptune based on mathematical predictions in 1846, so I assume that with today's computational power we should be able to either discover or rule out a planet 9 easily. I know, it's so far away that it's not really comparable, but I can't help but think that if we haven't found it by now, it doesn't exist. I would love to be proven wrong though, new discoveries in our solar system are always fun.
The discovery of Neptune was actually a fluke. If they'd done the calculation at some other time, Neptune would've been far from the predicted position. Calculating the orbit is one thing; where in the orbit is much more difficult.
So cool
Really been looking forward to this one :)))
Could there be a less cohesive aggregate of smaller bodies acting with the gravitational force we expect from Planet Nine? I picture swarms of small objects like Pluto's four moons, doing the Three Body Problem Waltz to a gravitational harmony we can't yet hear but see the effect of.
It could be made of dark matter.
Only reason I will angerly reject your Idea -- Not that it might not be true -- but only because you said Three Body Problem - Too soon Bro Too soon - Makes you look desperately trendy lol
Awesome a *TENTH* planet! Kickass!
Thank you for your comments on the process of science. I wish that was required viewing by pretty much everyone.

Hard to know what objects are located in the Kuiper Belt and beyond into the Oort cloud. If the primary planet/star is a brown dwarf we may never see it with telescopes but it can support planets and even planets with life. So one of its planets can be on an elongated orbit orbit (like a comet or like pluto's orbit) of 3600 years which is not an unreasonable orbit time. It would be that planet - not the brown dwarf itself which swings into our solar system. the planet on the elongated orbit would pass by all the planets in our solar system gaining astrophysics knowledge as a natural course of events.

Magnetron Sputtering always seems like something out of science fiction, even when you see it working.
"NIAC phase 2" gets my vote.
Secretly hoping that planet 9 is actually a primordial black hole. That could be a real gift of the universe for our system. I'm not sure if it has been ruled out though.
Planet 9's period is 3600 years (semi-major axis aprox. 234,9 AU) - it's a bit closer than the current estimates.
Scott Manley did a REALLY good black hole video sim some years ago on his channel in 360. Worth checking out....dude not only knows rockets but has serious computer skills.

I think you mean Planet 10. Pluto is Planet 9. 😎
I personally think the near side of the moon has those maria (apparently that's the plural of mare) due to the gravitational effects of the earth causing ancient volcanicity when the moon was much closer to the earth, much like Io's valcanicity is thought to mostly be caused by the gravitational pull of Jupiter. It's the most sensical reason I can think of in the 3 minutes since you mentioned it anyway 😅
An explanation (not originally mine) seemingly highly plausible, for the near-far sides lunar difference: A cluster of gigantic bolides hit the near side in ONE EVENT, lasting no more than a few days.
Argument: Since the moon rotates, impacts spread over time should be spread out in location of lunar impact. In contrast, the maria are clustered within one hemisphere. Thus, only one brief event, with only minimal lunar angular rotation occurring during that event
Wild implication: Since the bolide cluster struck the lunar side facing the earth, that cluster had to skim by the earth to do so. How many bolides instead struck the earth? How was our own geology affected?
I subscribe to the moon was closer - Which means it circled the Earth faster -- Causing the still hot moon to bulge the back side. Kinda like butt injection lol

3:36 “..hope it’s a planet.” The irony of Dr. Mike Brown hoping to find just another dwarf planet - no matter how large since it hasn’t cleared its orbit (see “Kuiper Belt”) - is well, ironic.
Of course there can always be another strategically orchestrated vote by his peers that will declare it is an actual planet by removing the “Cleared its orbit” requirement but adding one that it conveniently meets and other KBOs still do not.
If it's as big as Brown & Batygin estimate it will certainly have cleared its orbit.
@@denmaroca2584 , it can’t have cleared its orbit if it’s in the Kuiper Belt.
That’s like saying Ceres has cleared its orbit.. in the Asteroid Belt.
There is already too much explaining of why the cleared orbit “criteria” isn’t in play regarding the Trojans, in order to keep Jupiter in the family.
It’s problematic and should be debated. What a shame there isn’t a scientific body of SMEs who could take it up and work it out. Oh.. wait.. ;-)
@@denmaroca2584, shepherd planet!
@@PaulShanley What makes you think it will be in the Kuiper Belt? It's as likely to be considered as being so as Mars and Jupiter are considered to be in the asteroid belt.
The 'clearing the neighbourhood' criteria is about gravitational dominance and the Trojan asteroids are proof of Jupiter's gravitational dominance not in contradiction to it (just like satellites).
@@denmaroca2584 “..and (c) has cleared the neighborhood around its orbit.”
Not “has cleared its immediate neighborhood within the part of the orbit it is currently in,” when speaking the third tenet of the rule “What is a planet”.
See what I had to do there?
I had to think about what a “simple” definition actually means. What a word actually implies or in this case allegedly dictates. Especially when all the words in the 3 requirements to what is a planet - all those words - are being used to define.. a word.
There is more than mere nuance to consider.
Like does having large numbers of asteroids still _in_ your orbit mean you cleared the neighborhood _around_ your orbit?
No, because they are still _in_ your orbit.
That’s not what “around it’s orbit” means?
Rewrite the definition.
Make it make better sense.
I do understand its’ apologetics defined purpose (gravitational dominance) but as is, it is, not clear.
As is, and in light of Jupiters’ Trojans, it begs too many questions.
Doesn’t Saturn have the equivalent of Jupiters Trojans within its orbit as well?
Maybe the existence of three bodied, pushed and pulled clusters, of other masses within a planets orbit should be one of the definitions of what a planet is.
Or maybe, some honest, not rushed, un-manipulated venues, and numbers of delegates on both sides being present, debate, should occur about such things as basic astronomical definitions.
(Like should we even be using the word “planet” as the word for the now much more clearly defined as to what is a planet - considering its astrological-with-an-“L” pedigree?)
But I digress.
None of the aforementioned nuance should ever be “The mnemonic to learn all the new bodies that would count as planets if the ‘old’ definitions and ways continued, would be too long.”
lolol
