Why Psyche is Falcon Heavy's "Most Metal Launch Ever"
HTML-код
- Опубликовано: 27 сен 2024
- 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

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!
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.
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.
The runtime of this video is 13 minutes and 13 seconds on friday 13th 😱
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.
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.
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

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 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 😅

"New Glenn... set new standards for large rockets launching small payloads" 🤣
Confused me too....
Thanks for all the info, Scott! 😊
Stay safe there with your family! 🖖😊
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.
Note that the video is 13:13 long... well played Scott, well played
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!
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!
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.
Totally love your analysis And Commentary on these missions.Keep on Carrying On! :)
Thanks for the deeper look.
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!
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)
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.
Go for it dude! I love watching you. 😊
Great story and fairly well. Explain I sort of understand what’s going on. Thank you.
Scott: You said _"three feet or ten meters."_
I think you got those values backwards.
Correct!
I love a great FPGA. Thank you for the very informative video, as always.
MFGA (Make FPGAs Great Again)
Dunno about you guys, but I'm psyched for this mission!
Haha, „sacrifice the core stage to the dark lord of deltaV“, love it 🤣🤣
Its amazing that this is the first time were using hall effect this deep into space
man..i miss the streams here on youtube, damn you twitter!
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.
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
nice video. quick correction @8:30 you say "3ft or 10m", i think it should be "3m or 10ft".
Love your content Scott. Amazing!
16 PSYCHE IS JUST ONE OF A DOZEN OF KNOWN METAL ASTEROIDS IN OUR SOLAR SYSTEM ! ! ! IMAGINE THE COMMERCIAL POTENTIAL, VERY LUCRATIVE ! ! !🤔
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.
Scott
Please explain to us mere mortals the different types of propulsion used currently
plasma...Ion...xenon...?
Thanks !
He did.
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.
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.
11:10 I always get nervous when I see a spacecraft hanging horizontally on a stand like that.
SHAME THEY CAN'T BRING SOME SAMPLES BACK ON THIS
MISSION ! ! ! I WOULD LOVE TO STUDY THEM ! ! !👍
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 .
It makes more sense to double, triple, or quadruple check the software. We have had way too many failures of launch vehicles and science missions due to software mistakes. It's frustrating to see a multi-million dollar and multi year missions fail, because of a simple software error.
As a programmer, making something that works perfectly the first time you deploy it into production is basically impossible. The difference is, usually the first deployment into production isn't a multi-million dollar space launch...
"I am not a simple software error; I am an exceptional software error!" -Hans "Coder" Gruber
About the error "What's it's motivation?"@@backwashjoe7864
The errors that appear long after a piece of software is commissioned are not the simple ones: those get found during testing. The ones that turn up late are (almost) always obscure and complicated, due to sets of circumstances that have extremely low probability or that no-one thought of during the testing phase.
They don't bother checking it because it isn't real. Luckily I downloaded the original footage before they could edit out the mistakes. The black parts, where the rocket seems to flicker and go black in places is due to a greenscreen/bluescreen error. If the 'tolerance' is set too high, the greenscreen will affect that layer too much. The result is you will have unwanted areas of black, as the software you're using will render out the video as if there is nothing background layer.
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.
4:50 The asteroid belt is about 2 times farther from the sun than the earth, so that even if the spacecraft is at the asteroid belt, it will have 5 W available, which is enough to power the engines (given that the other systems don't consume more than .5W).
I love how this video is 13m and 13s long. Well played.
1:20 and for orbital mining. One more building block for a proper space faring civilisation in sight :)
@scottmanley, EscaPADE wasn't going to be manifested on the same launch as Psyche - you're thinking of Janus, which is also a pair of spacecraft but headed toward two different asteroids. It was cancelled after Psyche's delay.
13:13 well played sir!
This is fascinating!
"Out there is an asteroid waiting to be had. If you think I'll let it go you're mad. YOU GOT ANOTHER THING COMING."
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.
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 Greek Psyche was also associated with butterflies. So the Iron Butterfly asteroid?
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
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*
I love the way our some of humanities most high tec things, look like cardboards boxes wrapped in bin bags held on with sticky tape.
NASA's FIRST HEAVY METAL MISSION ! ! ! IT JUST NEEDS SOME SUITABLE HEAVY METAL MUSIC TO HELP IT ALONG ! ! !👍
Hi Scott!
Fly safe!
Metal!! * headbangs *
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.
SpaceX sacrificed the core stage to the dark lord's of delta V....Love it!
The trip out to the asteroid will no doubt be a long, tedious process.
Nice graphics but I’d still prefer the old green lines on black from the classic 80s Asteroids game (and Battlezone !)
Amazing that they use cosmic rays as a source of radiation for spectometry. No need to carry its own emitter, more pyload space for detectors!
Yes, Scott, I believe that you would like to go and visit that asteroid just like me. If I had a spacecraft you would be one of my first choices. The lower g forces would allow us to truly fly with our space suits on its surface. Dreaming... 😌
The artist impression shots you put up remind me a lot of the Majora's mask Moon lol
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
It might be a great place to find a lot of dead musicians of the heavy metal genre. Too bad the probe doesn't carry a microphone. But the stages might be visible... This mission is awesome!
Okay, so I'm soma, and had to come up with something like that.
Three feet or ten meters? What do you mean Scott?
8:35 “…surface resolution of about 3 feet or 10 meters…”
I suspect you either meant 30 feet/10 meters, or 3 feet/1 meter. Either way, impressive resolution.
10 feet, 3 meters is the correct answer here.
The fact that the video is 13 min and 13 sec. Is 👌
and yes its the 13th....
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.
Origins: Scott - it’s a ball of blast furnace slag from previous civilisations that was ejected into space.
Trust me - I’m from Port Talbot - near the steelworks….
Why do so many of the artist impressions of psyche show these weird spires at the rims of craters? Is that something that could reasonably be expected?
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 :)
Someone must start a band called "Dark Lords of DeltaV" ASAP! The most metal band ever. 🤘🤘
11:55 "they're going to be flying on New Glenn"
yeah, sure they will, assuming NG ever manages to actually get off the ground.
I just did the conversion. Scott said the spacecraft carried 900kg of xenon. 900kg in old style measure is 1984lbs. How's that for a "woo-woo" moment?
Space Dude and his car 😅 good one.👍
The mission is a breakthrough in research for resources. What a wonderful time to be witness of such a global changes!
The probe even looks super metal with all that aluminum foil wrapped all over it…🤘🏾
"3 feet or 10 meters" unit mix match?
It was, yes.
Easy there, Scott. you show any more enthusiasm, we will start thinking that "Tim the EDA" has taken over your body. Great report on an exciting mission to an asteroid. My students are already working on the parameters for a follow-up mission that will not be built until we get information back from Psyche probe. This future mission will include a lander and sample return to Earth. it is a big multi-college NASA effort.
The long-awaited Psyche mission is very exciting for many reasons. I, however, am also delighted for the SpaceX 2nd stage team that they got to have some their work forever immortalized with elongated heliocentric orbit. It may not be as permanent as one of the Voyagers or New Horizons spacecraft forever wandering between the stars. However, it is a great deal better than a short fiery death soon after launch of their typical product. I wonder if the assembly team attached some memorabilia for future space explorers to discover.
Elongated being the key word :)
they forgot the laser miner module scott!
Some people get a bit carried away with this asteroid and think it is a massive lump of gold and other precious metals. It could be in part I suppose but it is more likely to be iron.
@12:00 "new standards for large rockets launching small payloads" ==> New Glenn. Funny.
11:55 great joke scott, had me rolling! 🤣🤣
it has aleays beed dazzling, how much the real look of space bodies did differ from the artists' impressions. Think about Rosetta, Pluto or others. Let us wait and see what Psyche really looks like!
Another great video from Scott, but with a mistake. The Escapade spacecrafts to Mars were never scheduled for a launch together with Psyche. That was the case for the two Janus spacecrafts, which were planed to visit other asteroids. They are not rescheduled yet and probably canceld,
I love the phrase "Dark Lords of Delta-V"
THIS IS VERY EXCITING STUFF ! ! ! ARE WE WITNESSING THE START OF AN ERA OF A GOLDEN AGE OF SPACE EXPLORATION ? ? ?🤔
Love the perfect 13:13 video length
I'm so frustrated that it shows as 13:12 for me. I've reloaded the page a bunch of times and that final 1 seconds still eludes me.
Doesn't having the engines off-axis generate a rotation of the spacecraft? I used to think this about the USS Enterprise too 😂
From the animation, it looked like there were 2 thrusters on each side. But off-center thrusters aren’t too much of a problem if they are angled to fire thru the center of mass. The Atlas V boosters and SSMEs had to do it all the time
@@janmelantu7490 Ah, thanks pal. Much appreciated.
Are hall effect thrusters more efficient than grid ion thrusters, or are there other benefits to hall effect?
I liked this video. I rate it 13 out of 13.
Could be around 50% iron, nice lump of metal to harvest in some distant future 😉
