- The Dawn spacecraft has moved to its final orbit, an orbit which will bring it down to 35km from the surface of Ceres. It's being placed in this orbit to collect better data from its Gamma Ray and Neutron Detector instrument to give scientist a better understanding of the chemistry.
- Hry
That Expanse reference tingled me :3
A true Kerbal vessel, going to places and staying for a while and then going to the next place.
Thank you for the update. I often forget about these spacecraft because they don't get as much attention as Juno or Cassini.
Hats off. I follow this stuff quite closely and your appraisal was informative to the point that it allowed me to tie the pieces together. A happy bunny of a subscriber.
This really is one of the best sources for more better space news info.
Twirlip Of The Mists I watch this and the every day astronaut, also that Anton dude that uses the space simulation engine a lot
Jose Alvarado Then you should check out John Michael Gautier (on YT), if you don't already know him.
Twirlip Of The Mists will sub to it now and check it out later, thank you.
No laws in Ceres, just cops.

I want to +1 you, but you're currently at 42, and I just have to leave it there.
@@brianflowers4217 ofc, someone ruined it thou :/ now, for that Ceres sitting in my fridge...
Well if there's no laws..Cops just eat Doughnuts. No one can break a law that doesn't exist.
Six years of continuous thrust, pretty amaizing even for an old Traveller referee like me!
I was checking out this broadcast and can't understand why I am not subscribed to your channel. Well I fixed that right away. I like your shelf, and great show and information
Thanks for this Scott! I'd kinda forgot about this mission.
Love the Expanse reference. I am currently reading the series.
Great content as always!
Your Outro music is so cool. I always let it play out till the end. :D
thanks Scott, really cool vid :)
Thank you. Been interested in Ceres for some time.
Enlightening! Many thanks!
Amazing images, I thought we would have to wait for another space probe to get that close.
Excellent presentation, Scott. :)
I really hope Hayabusa 2 and Osirisrex both work as planned and returns their samples for study.
What a beautiful video, accent and blue eyes. So handsome. Thanks so much. God bless you.
Wow, this is a spewtube aberration. Knowledgeable, intelligent commentary you can actually learn something from. Thank you.
Thanks for the video
Oh I love Ion engines.
No doubt there was a tower on Ceres with a flight controller in it saying - "Don't buzz the Tower, Ghost Rider. The pattern is full."
It was once covered in ice. Until the inners took it away.
Global warming caused it to melt, har!
@@JohnBoyDeere and AOC just couldn't save it in time , I guess they should've taken the advice and eaten those babies 😂😂😂
@@8simonking8 Care to explain??
@@JohnBoyDeere I guess you didn't see the lady trolling AOC at a convention for this supposed climate change? Talking about eating babies and AOC actually thought the lady was serious. OMG it was so funny! 😂😂😂
@@8simonking8 I heard AOC said she would never want to have twins. She said she wouldn't want to be pregnant for 18 months, har!
beltalowda!
Fucking Belters. MCRN for life
kraygus , you da captain now
Stay away from de AQUA! Tell all your friends! ;-)
Love your ksp vids keep it up♥️♥️🙌♥️
I really dig that outro music you have for a while now.
fascinating! thanks for the info. i'm a big fan of your non-gaming videos.
great video i liked it a lot very informative , thank you . i liked so much i subbed to your channel .
This is beyond nice =]
Hi thank you very much.
You didn't warn me that there was going to be a spoiler about the protomolecule!!!! Luckly I was able to shout over your voice :D (I'm currently up to the 4th book)
Watching this, and in the "up Next' box is Isaac Arthur's latest episode "Outward Bound: Colonizing Ceres".
Nice.
Oye beltalowda!
Wasn't Ceres upgraded to Dwarf Planet status some time ago? It might not be 100% accurate to refer to it as an asteroid.
It's both.
Yeah, clearly its perfectly spherical form had to be created when its components were still mushy. It's probably a more perfect sphere than Earth is.
Good video , beltalowda
Isaac Author has come good videos on colonization and just did one one on Colonization of Ceres
Nice! Water on ceres is a darn good thing!
It was nice that that reaction wheel supplier sent all it's defective stock to NASA.
Love yer vids Scott - almsot as much as I love yer accent. : p
Enlightening.
And here I thought Ion engines were still in the testing chamber!
Same! Also, I never knew some of KSP's engine were based off of real rockets.
They've been used a bunch of times before Dawn. The Russians were using them back in the 70s, NASA had them on Deep Space 1 in 1998. The Japanese asteroid probe Hayabusa had ion engines and Hayabusa 2 has them. And they're used in commercial geostationary satellites a lot these days, both as boosters to get to GEO, and for station-keeping once they're there.
I'm waiting for the comments that complain about you being everywhere.
The universe is our testing chamber
Justin Y. Youre thinking of that ecm drive
Let's go mine baking soda on Ceres.
Allen Post. That is Bicarbonate of Soda
Yes; but it sounds too silly to pass up...
Hey Scott, I just saw your recent video on Elite Dangerous. I’ve been watching your videos for about 2 years I think. If you’re looking to people to play with, and if you’re on Console (I thought I heard you say you were), look up Ryders of the Void. We come recommended on Xbox and have one of the larger if not the largest console based factions. It’ll give you plenty of people to help take down those thargoids. 😁
Ever since I read about Ceres, I've thought it would make a great base for mining the asteroid belt. Lots of frozen water (O to breath and H for fuel) and a 1/100th gravity pull means easy to leave with tonnes of processed minerals.
Finished season one of the expanse literally 10 minutes before watching this... what are the odds of that reference?!
I watched all three series of the Expanse one after the other. Looking forward to series 4.
Spaceships with giant particle beams as propulsion systems? Yes please.
legit still smile when I see a Manley video notification
Very nice expanse reference 👌 I’m actually made of protomolecule
I get those on the back of my tee-shirt after a sweaty day
Man, this missions are so exiting that I can't imagine how awesome it will become if the cost of access space goes down.
We're probably going to have a probe (or probes) orbiting every significant body in the solar system if BFR/New Glenn work out.
Hi Scott, interesting insights, tnx.
Recently I came across some rumours that Russians work on an iodine engine and also progressed in development of a Soyuz replacement vehicle, would be cool to see what's your take on this matters, cheers
Fly safe ;)
Thanks Scott! Will they impact the spacecraft when the stabilizer fuel runs out or fire the ion thruster to ensure it can't deorbit?
In the future Dawn along with various other space probes may be recovered and wind up in an equivilant of the Air & Space Museum
You could say at Ceres they wanted to get data as VESTA possible. "Hey let go of me, I can walk...aaaaaah".
Eros was just where the protomolecule was being tested. It was initially found on one of Saturn's moons, Phoebe.
*Scott Manley* Is that a spiral staircase?
Keep up the good work. Glad to see you _ON INDEPENDENCE DAY_
6 years of continuous thrust bloody hell
It's really amazing that it didn't go dawn
Even when it runs out of fuel, it could still provide occasional new data until it's orbit is broken by either falling into Ceres or falling out of orbit of it. It's got solar panels, so power for the equipment won't be a problem for a long time, and it probably has some working reaction wheels, so it should have limited ability to rotate...
The problem with what happens after it runs out of reaction fuel (or has the reaction wheels break down) is trying to orient the spacecraft to transmit any useful information. The antennas need to be aimed at the Earth, and if that can't happen then any data that the computers pick up simply won't be detected by the "Deep Space Network".
Yes, it is possible to have an omnidirectional antenna (aka something which can transmit and receive in any direction), but those kind of transmitters either require a whole lot more power or need to be much closer than several astronomical units of distance away from anybody capable of picking up their signals. That can work for satellites in orbit around the Earth, but not around what is arguably another planet of the Solar System.
You could still use the engine for attitude adjustments
Glander, this is one of those rare times Scott Manley is not entirely clear. He said it was loosing reaction wheels, but not how many it has still working-if any. I think it lost them all as he commented that it needed the engine for attitude control, but I know about as much about space as the average NASA test chimpanzee. If they put it in a very slow tumble right before it dies, it can still be ordered to burst transmit when its orbit is in line with the earth, and receive information any time it's antenna is pointed close enough to earth, so having no control over it does not necessarily mean it's completly dead.
The problem with reaction wheels is that they are mechanical systems. One of the problems that exists for any mechanical system in space is an issue with vacuum welding that happens on any mechanical part. In a vacuum (like... in space) metal parts in close contact with each other tend to become literally welded to each other... just like you used a welding torch to them. Lubricants tend to evaporate over time, and even ball bearings will tend to weld themselves to any parts they are physically in contact with over time.
Simply put, a reaction wheel is really only good on average for a couple of years at best. You can put it in a pressurized environment (build a box around the reaction wheel), but that adds mass and complications where the gasses can still leak out and get you back to the same situation.
The Dawn spacecraft has been in space for over a decade now and has already visited three worlds. Even the main ion engine is likely running out of fuel (even though it uses comparatively little fuel.. Xenon gas... in any single instance). It is an older spacecraft that is simply breaking down since it is well beyond the expected lifetime of how long it was designed to be used.
The slow tumble you are talking about still requires the spacecraft to have the plane of the spin to at least be in line with the Earth some of the time... but that may only be for a couple days per year since not only is Ceres moving around the Solar System, but so is the Earth. Even if perhaps you could once in literally a blue moon get some modest amount of data from the vehicle, it is effectively dead.
There is also the cost of running the "Deep Space Network" to even detect the signals from this spacecraft. That is billions of dollars worth of equipment around and on the Earth and something that costs hundreds of thousands of dollars to operate... each day. It is also tasked to collect data from every NASA spacecraft, so they prioritize missions including newer missions that pop up. There reaches a point where even if perhaps some data is being sent by a spacecraft, that NASA simply pulls the plug on the project and moves on. The Dawn spacecraft is nearing that point too.
GlanderBrondurg they can use non metallic parts
6 yrs of continuous operation for an ion engine is phonomenal!
So now from the sun's perspective, Dawn is moving in parallel to Ceres. :D
Great second name
It does have a certain ring to it.
I first thought the two lights on Ceres was sign of a Motel 6 leaving its lights on.
Ah. Thanks for a vid on Dawn. Mission get's no respect.
Whoa whoa, just because they're crazy doesn't mean they think it's aliens lol
They really should pack these observational craft off with spectrometres.
That thing looks like a moon. Huge
Can you imagine needing to do a six-year burn in KSP?
Ieago i feel like scott did something like that once
With physics acceleration x4. Alt >>>
It would only take 1.5 years.
dosmastrify In Interstellar Quest he did one that lasted a day at 4x time acceleration...
I believe there's some mod which allows insanely high physics warp speeds, if your PC can handle it.
Or there's also one that enables engines with on-rails timewarp
ya, I don't have a clue how you figure out burns like that. Probably lots of differential equations.
I prefer to call Ceres a planet.
Hasn't cleared its orbit. If Ceres is a planet then there are a hundred or a thousand planets. And why not the moon too?
Neither has Earth, Mars, Jupiter or Neptune. Round from it's own gravity, not massive enough for fusion = planet.
Protoplanet. Growth was cut short before 1 Ceres became a genuine dwarf planet.
I didn't know ion engines were real,btw how much delta v does the craft have now
So the white spots are basically efflorescence, same as the white marks you get when damp comes through brickwork.
Im writing a book where Ceres is going to hit the earth. Its nice to be able to get to see it up close without it having to actually smash into the earth lol
So. What you're saying is... Limescale. 😉👍
Seems that ion engines are viable.
How long ago did we get these pictures in? It can’t have been long.
ion engines are superb. I suggest everyone use them on their probes in KSP. Just have a better time warp mod. And make sure you have solar panels or radio isotope generators for outer planets
I really did LOL at Protomolecule...... Some people wanted it to be Aliens wishful thinking.
I ain't afraid of no protomolecule :D
The giants of Ceres seem to be dormant.
Don't forget the ion buffering aperatus chamber
It would be cool if it went for other targets
So what would they end up doing with the spacecraft after its xenon fuel runs out? Would they just keep it in orbit or use the last of its fuel to impact it into Ceres?
Scott Manley do you know whether it has enough fuel for a return into an ultra-elliptic earth orbit, so it can be brought back
Imma super Ceres!
Looks like just ice to me, it's cold in space!
Actually, I believe he's quite 'Ceres'ious' here..sorry, I'll leave now.
I've always pronounced it as something more like "Seh-ress", but "Series" kind of makes more sense.
And regarding missions to asteroids, I want someone to send a gravity mapping spacecraft to 90 Antiope.
"Kind of makes sense" is only an illusion. You should not blindly trust an American, or in fact, any Anglophone, to be an authority on the pronunciation of non-English terms and names. Especially not Scott "Worrnrr vonn Bronn" Manley.
it can occur only in nuclei somewhat heavier than nickel (element 28), where the overall binding energy per nucleon is no longer a minimum and the nuclides are therefore unstable toward spontaneous fission-type processes. In practice, this mode of decay has only been observed in nuclides considerably heavier than nickel, with the lightest known alpha emitters being the lightest isotopes (mass numbers 106-110) of tellurium (element 52). Exceptionally, however, beryllium-8 decays to two alpha particles. ahahahahaha
im pretty sure all those are lighter than nickel
We should, at some point, put a transparent geodesic sphere around Ceres!
Would it be so cool
@@Rafael-lr4gn Eventually it should form a greenhouse effect...
so what is the convention for naming dwarf planets and dwarf planets surface features ?
I never realized Ceres was that large, I always pictured more of a potato-shaped rock rather than a round and cratered moon.
I guess I can see now how it could have been lumped in with the planets upon discovery.
Hay Scott do you play star wars x-wing miniatures game or did you get the imperial gozanti-class cruiser cuz its cool
Perfect timing! I have been mulling over those white spots for months! If I were Elon I'd launch a mission to recover some of those white flakes. tytyty!
Still waiting for photos of the Apollo-landingsites with more than 5pixels :)
You know the Apollo astronauts took pictures when they were there
Too bad the probe doesn't have a lander, would be so cool to deploy a little exploration rover on Ceres.
Let’s be honest, if it were alien cash sites it would be so dam awesome!
The chances to hit such a small object to crash are probably not very high.
Unless it was a crash during attempted refuel.
why would aliens keep their cash on ceres though?
Depends on the exchange rate.
These big space boulders are missing in Elite Dangerous.
Wow messy house!
Why does it look so different from when They First showed it?
I hope this is a ceres.
