Why Psyche is Falcon Heavy's "Most Metal Launch Ever"
HTML-код
- Опубликовано: 12 окт 2023
- The Psyche mission is a NASA spacecraft which is going to investigate the largest M type asteroid in the solar system, M type asteroids are presumed to be metal rich, and the processes that lead to these asteroids are important in understanding the formation of the solar system.
Psyche was built by JPL using a commercial 1300 satellite bus, and launched on a Falcon Heavy on Friday the 13th.

It'd be awesome if you made a video on how artists impressions of celestial bodies have compared to the real thing. Especially going way back to the dawn of the space era.
why just look it up
absolutely golden video idea
@@blakespower
Too easy. I often ask questions in comments rather than googling.
Why. Because others on the thread may be interested. Or a fellow subscriber may have a personal answer.
Does that reply suffice?
@@blakespower ... or we could count on someone with broad knowledge of stuff who's a great explainer and has a soothing voice to boot to make an informative and entertaining video on the topic that would bring this information to potentially millions at once.
I'd watch That video!
Worked on the thermal blankets for Psyche during my time at Maxar(Space systems Loral). Super happy to see the closeup shots of the thermal blankets in this video! It was a strange program in that the satellite spent a lot of time at JPL TVAC chamber and we were shipping thermal blankets there instead of installing them ourselves in our own high bay. This led to several funny stories; one where blankets would get lost and found in an unopened box to which JPL said they would not open unless we send them instructions on how to open the box!
Give them credit - probably more than one item inadvertently getting destroyed by someone in the mailroom with a box cutter.
@@fredinit Absolutely! These blankets are thousands of dollars and it makes sense they needed instructions. It was just funny finding out the reason we were delayed was because of box opening instructions.
@@fredinit Oh yeah - I learned the hard way, by knifing the contents of a box. (Flour, or something along those lines, spilling out of the bag I sliced open.) Now I cut the tape verrry carefully.
@@jpdemer5 And that is why box cutters have a depth adjustment. Open them up to the thickness of the box material at the most and you should be safe. You don’t need 3cm of blade to cut through the tape.👍
@Markle2k My kitchen knife lacked a depth adjustment. I should get better knives.😄
I saw this launch in person!! It was absolutely incredible, my first time watching a launch after moving to Florida. The noise was incredible, made my car windows shake too.
I know the feeling. What a privilege to witness this first hand!
Am envious: I was set out to fly out from California to view the scheduled Thursday launch, but with the bad weather projected for Thursday I canceled. Will definitely try to make the next Falcon Heavy launch that features RTLS for the side boosters (was at the Saturn V Center at Kennedy for the Artemis 1 launch and it was spectacular).
@@1Esteband Nice, I was able to see a shuttle launch while on holiday in Florida (pure luck, was just a trip to Disney for the kids) I always thought the crackling noise I heard on tv was just the microphones overloading... but no, that thing CRACKLED!
So jealous. I would love to see a Falcon Heavy launch/landing.
Living next to the cape, what was notable about this FH launch was how staggered the booster landings were. Even NASASpaceFlight was wondering where the second side booster was after the first one had already landed and double-boomed.
The runtime of this video is 13 minutes and 13 seconds on friday 13th 😱
Not trying to second guess JPL, but it seems scary that such a thruster issue (exceeding thermal limits) was found so freaking late in a mission that was already a year behind schedule. Hoping no other "gotchas" show up in the next 9 years.
That’s why Murphy’s law became a thing.
NASA puts in double or triple protection. Because
Anything that can go wrong.
Will go wrong.
It's okay to second guess JPL they kinda messed up on this mission
@@unnatural_log6472yes, as Scott mentioned they were overbooked trying to do this mission and run ragged. That's why the software fell so far behind the timeline. They are the best at what they do but even the best people need time to do their work with due diligence. A good project manager would have stepped up to the plate for their people and told the head honchos that they needed more time. Just glad it seems to have worked fine so far and hoping it will complete its mission with flying colors.
I am biased since I work at JPL, but I think JPL deserves some slack because almost the entire construction and testing of the hardware and software was done during the pandemic.
That was unfortunate with all the restrictions in place during those times. Glad it is on its way. Will be interesting to see what it tells us about these "metal rich" asteroids and about the early solar system once it arrives and performs its 2-year mission at 16 Psyche. I read there are only 9 such asteroids like this. That alone is curious.
Worked on this mission as a supplier for JPL! Once in a lifetime experience. 🤩
Great! What were you supplying?
@@longboardfella5306 It was equipment related to simulating conditions on the space craft while en route through space.
28 grams isn't about 2 ounces, it's about 1 ounce. And 3 feet resolution is not about 10 meters!
Are you OK, Scott? It must be the effects of Friday 13th in action!
on the other side, i would just blame stubborness that these weird woobly Units converted from SI Units are still in use anyway
😂😂😂 caught that one too….
Just swapped ft and m it sounds like lol
Human moment. Everyone does it.
The paper on the PMI gives a resolution on 10m from 200km distance, so about 30+ feet/pixel
[elib.dlr.de/110238/1/bell_1366.pdf]
Great overview of the Psyche mission! Minor correction: 28 grams of thrust equals 1 ounce of thrust, not 2 ounces. Despite going to a heavy metal asteroid, the gram-to-ounce conversion ratio didn't change ;-)
And 3 feet surface resolution is not equivalent to 10 meters. I say a witch poisoned Scott's water with an albino bat extract potion.
@@kngofbng Lol -- I missed that. I agree (by Occam's Razor) that your explanation is the most likely one ;-)
scotts weed man must be gypping him. "yea man its two ounces, trust me"
Many people know this unit conversion, but it's rarely taught in schools. I'd say there's a "botanical" explanation ;).
I thought each thruster had 28 reams of thrust and there were a couple dedicated to acceleration.

You say the resolution is 3ft or 10 meters... Wouldn't it be 1 meter?
lol.... got that backwards
The paper I read indicated 10m resolution. Was that info just out of date or am I misunderstanding the paper?
elib.dlr.de/110238/1/bell_1366.pdf
"The PMI cameras are fixed-focal length systems providing images with an instantaneous field of view of 0.05 mrad, a field of view of 4.6°⨉3.4°, and a depth of field from 800 m to infinity. PMI ground sampling distance is 10 m/pix from an altitude of 200 km."
It's 3 meters or 10 feet
Erm... so, which one is it..?
3ft is approximately 90cm
My son and I watched this launch. I just can't wait to remind him of it launching when he is almost 10 years old when it finally reaches it's destination orbit around this asteroid.
I think it’s very cool that they’re using a 100 year old telescope to try to receive the data. What would the builders of that telescope have thought if you told him that in 100 years it was going to be used for something like this?
Good point, their minds would be blown! I agree, it’s fantastic to see an historic but amazing instrument from astronomy’s past being re-used to a fantastic purpose. Not entirely sure as it’s somewhat removed from civilization but it’s possible light pollution limits the usefulness of this telescope now, given the unreal and explosive growth that has occurred in California in the intervening century. Also, purely the amount of lumens per person is probably at a minimum 10x what it was back then.
so much of the technology here would be completely incomprehensible to those early astronomers, it is an interesting thought. LASERs are ubiquitous in the modern world but weren't even imagined back then, not to mention solid-state electronics and integrated circuits. It is funny how after all these thousands of years we're back to relying on the basic principle of a signaling lamp.
100 years ago there were still horses pulling wagons on dirt roads 😅
The teller of said news woulg be burned as a heretic
@@tissuepaper9962as well as space travel it’s self!🤷🏾♂️
Thanks for all the info, Scott! 😊
Stay safe there with your family! 🖖😊
"New Glenn... set new standards for large rockets launching small payloads" 🤣
Confused me too....
It always amazes me the amount of time it takes to reach something only within our solar system. I think every mission should have a little digital recording that contacts mission control every so often and says "Are we there yet?". Because lets face it, most people working on these missions think of them like their kids.
I do believe they do little status pings from time to time. Would not surprise me if someone wrote a little script where the status updates subject line is "I'm bored", "Can we stop at McDonald's" and of course, "Are we there yet?"
@@journeymanic9605 They could run a competition and the winning kid gets their voice used. We could add more like "I need to go to the toilet"
Totally love your analysis And Commentary on these missions.Keep on Carrying On! :)
Thanks for the deeper look.
And your video time is 13:13. The launch was absolutely stunning, and that cacophony of booms on the booster returns!!!
Man SpaceX is killin it!!
Made it out to watch this as my first launch, it’s even more amazing to watch the boosters come back. One of the interns was nice enough to give me her Psyche lanyard, now it’s my most prized possession!
4:40 28g is only one once, so one once of thrust, not two
But times 4 don't forget. I wonder what acceleration that gives over time?
@@keithhoughton4308 you can't just refer to the thrust of one engine in metric followed immediately in the same sentence 4 engines in imperial and not get called out.
And actually not too bad, the craft weighs 5750KG so 112g of thrust gives 0.1948m/s/s or 0.639ft/s/s.
It's always unnerving to me that, at my age, these long missions may not complete before I'm dust, back in the ground! 😂
All too true about living long enough. I want to hang around for the next few hundred years to see if humans will move off the earth. And if they colonize far enough away to avoid the entire human race someday getting caught in a stupid apocalyptic human war.
You and me both, Phil
Me too Phil, but great to see them go off. And don’t forget, we were lucky enough to see the first moon landings. Can’t beat that!
Note that the video is 13:13 long... well played Scott, well played
VERY EXCITING STUFF ! ! ! I HAVE BEEN WAITING A LONG TIME FOR THIS 16 PSYCHO MISSION ! ! !👍
"Space dude in his car"???
No love for Starman?
The coolest thing ever put in space!
Love your content Scott. Amazing!
Go for it dude! I love watching you. 😊
Great episode!!
Great video, Scott...👍
thanks for the summary of the mission, great stuff as always
It takes so much patience to follow these missions. I'm excited!
Compared to missions like Voyager or New Horizons, it's not too bad!
1:25 I hope they made sure that guy got out!
Very well presented, Scott.👍🏻
Good report, Scott. Very interesting.. I would like to see some more technical specs and view of the components.. keep it up.. you have my attention.
Are you sure you don't have a 10 person writing staff? These videos are awesome!
And another 10 people editing!
And 2 more guys to post these comments. ;D
Okay, 3.
Outstanding and informative, as usual.
Thanks for the lucid explanation Scott.
Great story and fairly well. Explain I sort of understand what’s going on. Thank you.
I love a great FPGA. Thank you for the very informative video, as always.
MFGA (Make FPGAs Great Again)
I was at Cocoa Beach all week, but both the Starlink and Psyche launches got pushed back to the day after I had to return to Texas. So I got to see no launches, but we did a lot of other fun stuff in Florida and got to see Space Shuttle Atlantis over at Kennedy Space Center. It was a great vacation. :0)
I've been waiting for this one ever since it was announced. I really help it goes without a hitch.
10:30 looks like there's quite the wind in the cleanroom. That material has to be incredibly thin and light.
Nice one, a broadcast length of 13m 13s on Friday 13 Oct...let's hope the 13s all don't come together as they did 53 years ago on Apollo 13. Spot on great information, interesting as always. Happy weekend.
Scott mentions Palomar Observatory - great place to go and visit if you live nearby or are ever in the area! Up on top of Palomar Mountain in northern San Diego County (lots of other cool stuff to see and do up there too - State park, restored / active fire tower, great views, hiking, etc.) The observatory has a great little museum out front, and you can go up stairs inside the Hale Telescope dome and view the telescope and working floor through an array of windows. On weekends during the summer months, you can also pay a small fee to go on guided tours of the working floor and see the telescope up close. Really neat...highly recommended!
Its amazing that this is the first time were using hall effect this deep into space
Scotty my boy, if you are ever confused with how many grams are in an ounce or vice versa, just ask a pothead. 28 grams is one ounce, not two, lol. Just bustin' your chops. Great video as always, keep it up, man! Your perspective on things is always refreshing compared to the rest of the media.
So true lmao
Tokers to the rescue!
I didnt get to see the launch live but i saw it in replay and wow it was amazing! And i did get to see the third stage and such be done live tho
This is fascinating!
Excellent description of the gamma and neutron detectors thanks! (Nuclear physicist here.)
Thanks for the vid. Ive been excited for this mission for a bit. Its been a good year for astrophysics: Osirus Rex, Psyche, and soon Europa Clipper. *crossing fingers*
Haha, „sacrifice the core stage to the dark lord of deltaV“, love it 🤣🤣
wow I was trying to search this before but all youtube gave me was the current live mission
Awesome video I like all your videos best. In the way you have your ending with the little space man in a rocket Going Out of space.
Dunno about you guys, but I'm psyched for this mission!
Did you notice how quickly the heavy cleared the tower? Guessing this thing accelerates probably 35-40% faster than almost anything.
The runtime Scott!
Hi Scott!
Fly safe!
Metal!! * headbangs *
Hey, Scott, great video as always:)
Have you heard of the Spanish company pld space? They just made history as the first private eu company to successfully launch their own rocket (Miura 1) and land in the sea (first ever Spanish rocket also). Granted not orbital yet but their Miura 5 will be and I think they aim to try and launch and recover that one next year... Anyway it seems like they deserve some more love for what they have archived in the English speaking world, as so far I see no one talking about them.
IIRC that was in one of his recent deep space updates
While it's obviously fine and done after careful consideration, having worked in a cleanroom - where you want steady laminar downward airflow - I was aghast at the JPL publicity shot team pointing a carpet-drying fan on a cart up at the antenna cover film to make it flap in the wind.
The film flapping against the stuff underneath also just looks sorta stupid, fragile, and chintzy. I don't think I've seen that particular trick done before, and I don't expect to see it again.
It doesn't have to be functional because it is simply pantomime. Just like the old Lunar Lander held together will tape and tin foil. The mask is slipping. You're starting to wake up as I see many others are too. They are laundering money through a fake space program. Why waste that money on something that looks the part if only 5% of the population will notice.
Thanks 👍
man..i miss the streams here on youtube, damn you twitter!
@8:35 " ...that translates to a surface resolution about 3 feet or 10 meters in the lowest orbits."
Maybe that's 3 meters or 10 feet?
Correct!
I know you did a video on reaction wheels a while ago, but those offset thrusters really make me think about the mission profile and how long burns are performed with torque being applied over a very very long time. Do they roll the probe 180 and start desaturating the wheel, then desaturating, then roll and repeat? That cant be very easy to roll with on an axis perpendicular to the saturated reaction wheel axis. Maybe it is, idk.
As far as I have seen, the thrusters are in pairs on both sides of the craft. So they will probably always run in parallel resulting in no residual torque.
What I do not know is, why they only show one thruster firing in the animations. :-?
13:13 well played sir!
very cool mission. at 4.5 gm per cc, it really isn't a solid chunk of metal. my guess is that the outer 30+km is going to be the same stuff we just got back from Bennu. So much to learn.
probably something like iron ore??
gm = gram.meter
ha, I didn't even think about that, should have just used g. thanks...@@kngofbng
@@kngofbng cc = c²
When they talked about Bennu being over 4 billion years old, my first thought was "How much gravel & dust was in the solar system since then?". My gut tells me it could be enough to fully comprise all asteroid samples we can collect from the surface. I haven't heard this question addressed enough.
Scott: You said _"three feet or ten meters."_
I think you got those values backwards.
Correct!
Space Dude and his car 😅 good one.👍
nice video. quick correction @8:30 you say "3ft or 10m", i think it should be "3m or 10ft".
Isn't it likely that even if it's shiny metal, it will have a dust layer over it? The artist impression looks as if the thing was just powerwashed.
also at 8:35 3feet=10m can't ba right.. should be 1m i guess.
Given its lowest orbit, it was probably supposed to be 30ft = 10 meters, rather than 3ft = 1m
Yes, it's likely grey scale. :)
Scott got the order wrong, he replied under another comment. 10 ft, 3 m. I've run the numbers to confirm, that figure is correct.
I like how the spacecraft looks like a bat and was launched in October. I didn't know about the laser, I was pretty worried about the deep space network so I hope that experiment goes well.
Mr. Manley, Starlink v2 mini use ll effect argon ion thrusters. So this is not the really first Hall effect thrusters, just the first xenon ion hall effect thrusters. The Vqw mini went with argon ion for cost reasons, and then went to hall effect to get the Isp back up. Engineers!
Go back and listen to what I said again.
Scott, I'm interested in your comments about the off axis thruster location.
Even taking into account there may be some heavy hardware on one side of the craft, that remote located, one sided thruster looks like it will just spin the whole spacecraft around.
I mean it really only depends on whether the thrust vector is aligned with the center of mass. Doesn't really matter that it is"off to the side" based on your perspective of forward. Center of mass will determine what way forward is when firing a thruster
@@zacrintoul Correct and it's only an animation, just the way it is rendered it will spin itself into oblivion
The video doesn’t show it well, but there are two of those large thrusters on both sides of spacecraft. In addition, they are on gimbals so they can control their thrust direction.
Spinning to point the sat may be the purpose .
Scott, I've got 2 duroc sow's that expect to fly the week before New Glenn!
Scott
Please explain to us mere mortals the different types of propulsion used currently
plasma...Ion...xenon...?
Thanks !
He did.
The artist impression shots you put up remind me a lot of the Majora's mask Moon lol
Snarkey :) I Love it!
I love how this video is 13m and 13s long. Well played.
Merci!
missions like these blow my mind. so many difficult things to get right and one little mistake and there goes a decade of work and billions of dollars. you gotta be a strong individual to work through that level of pressure and anxiety lol
11:10 I always get nervous when I see a spacecraft hanging horizontally on a stand like that.
Any interest in gathering data that would support interplanetary habitat - the idea that resources will be much less expensive if available off Earth. ? Really appreciate the extended rundown of the spacecraft, systems and sensors. Well done !
All he could do is guess.
SHAME THEY CAN'T BRING SOME SAMPLES BACK ON THIS
MISSION ! ! ! I WOULD LOVE TO STUDY THEM ! ! !👍
Excited for this one. Even if Psyche isn't as completely metal as we'd first thought, it's still a juicy target for humanity's future in space some day...assuming we last that long.
Thanks for the insights as always! Still I was wondering if you meant to say 3m / 10 feet (8:35) or if there was another thing I didn't get.
could you make a short episode about the controlled environment thay have in those space probe assembly rooms? I see a lot of air moving in the video :), I suppose it's there to remove any particulates, microbes, dust, hair, aerosols, what I was not aware of is how strong the airflow is. Well at least it looks like it's quite windy inside :)
I'm glad to see both cameras are facing the same direction which should make stereoscopic images possible.... I wonder if they gimble as aiming the pair specifically could be useful. Ah, wait, taking two images successively with the same camera can accomplish the same stereoscopic effect as the probe in its orbit will provide separation between successive libes of sight. Maybe 75km is too far to make either technique viable anyway? And I suppose laser, radar, or lidar scans can yield topography anyways... Still stereoscopic photos are fun to view amd super old-school.
According to the paper on the PMI...
Stereo imaging is nominally planned to be acquired by using just one camera and operationally acquiring ≥ 3 images of each surface element at nadir and at up to ±20° stereo separation
what size telescope would we need to be able to clearly see [surface] details in the asteroid belt. From an Earth orbit or L point.
Can’t wait to see what it looks like. Will it be metal ore or solid metal?
I'm guessing it will be more like a metal sponge with rock in the voids.
16 PSYCHE IS JUST ONE OF A DOZEN OF KNOWN METAL ASTEROIDS IN OUR SOLAR SYSTEM ! ! ! IMAGINE THE COMMERCIAL POTENTIAL, VERY LUCRATIVE ! ! !🤔
8:39 Scott, I presume you meant a surface resolution of 3 meters or 10 feet. (It doesn’t work out so well the other way)
11:55 great joke scott, had me rolling! 🤣🤣
Are hall effect thrusters more efficient than grid ion thrusters, or are there other benefits to hall effect?
I guess we will learn more in 7 years.
At least there are several other deep space rendezvous in the next few years with Lucy for example.
My dad's flight to florida was redirected b/c of this launch, and he god pictures of exaust clouds/streaks through the sky out his window.
The Greek Psyche was also associated with butterflies. So the Iron Butterfly asteroid?
I liked this video. I rate it 13 out of 13.
I was just thinking maybe if you landed on an asteroid and then screwed into the asteroid, maybe you can chuck little chunks of it back to Earth. I mean using something like a robo pitcher than runs on solar or rtg energy. Yes there would be a reaction force, but balllistically maybe you could do both at the same time. Or chuck it to the moon for pickup.
You might well be able to throw rocks into an asteroid's orbit or beyond, but to get the material's _solar_ orbit to go in as far as Earth or the moon from the main belt, you need to launch your stuff at 8 kilometers per second or more. (some near-Earth asteroids get as low as 6 km/s delta-v.) Tank cannon sabot rounds go up to 2 km/s. It would call for "superconducting magnetic mass driver tunnel", not "cute little robot box with a spoon" :)
The mission is a breakthrough in research for resources. What a wonderful time to be witness of such a global changes!
The fact that the video is 13 min and 13 sec. Is 👌
and yes its the 13th....
