I want to know more about the sapphire insulation! Mind blown!

@TusharKelshikar 5 лет назад

That and how were the orbits chosen. I mean, if we're going to Mars for instance, we usually pre-select the sites we would like the spacecraft to fly over. I hope Periodic Videos does a video on all these fancy metals.

@dimesonhiseyes9134 5 лет назад

Sapphire really is amazing. Most people are just too used to it being used in jewelry and it just kinda goes by unnoticed but it really is amazing stuff

@anthonycase 5 лет назад

The main reason we use sapphire is that it is a really good electrical insulator, even at really high temperatures. Especially important in this application where we have to sustain up to 6000 volts!

@qfc1313 5 лет назад

Is there anyway to see a picture of the inside?

@htmagic 5 лет назад

Sapphires were also used on the 30,000 psi water jet system that cleaned the shells of the booster so they could be reused (up to 10 times). It's amazing that water at that pressure would erode even the hardest materials and even the fine sapphire nozzles got worn and had to be replaced! I know because I toured the Cape Canaveral Air Force Station next to Kennedy Space Center and saw where they took the booster shells segments on rail cars, cleaned them, then they would reassemble the segments (with the famous O-ring seals) and refill with propellant.

@BrianChristmas 5 лет назад

I love it when intelligent people can talk about a subject in a manner that makes sense to me, the average Joe. The manner in which you, Destin, asked Dr. Case questions was very well done and extremely helpful. Great video!

@Varksterable 5 лет назад

This is definitely one of the best scientific interviews I've seen. Enthusiasm, knowledge, character: check. (Not entirely sure about Destin's selfie shots, although having him in the footage is fine - tripod anyone?) But overall this is just +++.

@spicy110 5 лет назад

I get the feeling after all the interviews he did that day, this was the first interview he got to talk about the things he loves the technical and science side that most interviews just won't care about. That's why I love this channel it really is for people like us. If you are reading this you are on this video and I know you get what I mean.

@enoughofyourkoicarp 5 лет назад

So when I was a kid I took a cup of water out of a pond to see what was in there for a school science project, now these guys are taking a cup of star light to see what it does before it ends up in my pond. I find that both awesome and beautiful at the same time.

@Pants4096 5 лет назад

I've said it before, but here I am again: Your enthusiasm for learning, wonder, and exploration is so infectious. It's the root of why these scientists do what they do, and when an interviewer like you shares that same passion you can see in their eyes a shared excitement and love for the universe. THANK YOU for your excellent work bringing these conversations and topics to us in this unique medium. Did you ever imagine, way back when you and your sister first demonstrated that silly chicken's head-stability on youtube, that you'd be interviewing people like Dr. Case? Keep up the great work!

@HugoDahl 3 года назад

I loved seeing just how _thrilled_ Dr. Case was to talk about the science which he obviously really enjoys. That is a person who is doing what they love, and seemed like he really had the right audience with Destin, who knows enough engineering to ask the good technical questions, but not in the right "type" of engineering to shed light on what they do, and how they do it. This has been a fascinating and eye-opening series!

@robsadler5605 5 лет назад

This interview with Dr. Tony Case was absolutely amazing! Thank you Dr. Case and Destin for providing us with the opportunity to enjoy and learn about this project.

@Varksterable 5 лет назад

All the full interviews are amazing. I didn't watch them at first, assuming Destin had just edited the dull bits out on his main channel. WRONG. The passion, intellect and enthusiasm these people have should, imo, make these mandatory watching for anyone who can even vaguely comprehend them. Truely smarter every day.

@alex0589 5 лет назад

Well, we are here with the same background and for the same reason. Difference is that Destin made enough "trailers" to get me on board a long time ago. Now I just follow and watch what ever he makes. Chances he make something that would interest me are pretty good. And of course I would love to see "full length episodes" on all the other topics he might have material for regarding the Parker thingy. A am fully aware this is _my_opinion_ and Destin should do whatever _he_ feels right.

That's fun and all, but at the same time, I want more direct avenues to hear from the brilliant people doing such inspiring work on the behalf of humanity. Science is done for everyone, and I have so many questions like mark Roper's in the comments here.

@markroper9269 5 лет назад

Awesome videos! I want to know more about the screens on the collector, more about the construction of the shield protecting everything, how do those magnetometers do what they do and function to provide data, and the solar panel cooling and the "dump" of excess heat to space. I studied physics, chemistry and biology in college.....ended up in construction, the travel business, and IT. Thank you for sharing that glimpse into "hard" science in a way most of us can understand.

@anthonycase 5 лет назад

The screens (or "grids" as we call them) are made from a monolithic piece of tungsten that is then chemically etched (they mask off the bits we want to remain, and then etch away the rest). The result is a criss-cross pattern that is 90% empty space and it allows us to create an electric field in the instrument, but still allows particles to flow through them.

@Kockafalva 5 лет назад

stupid question: If the offcenter gravity to the center of pressure is causing so many problems and fuel usage (by desaturating the reaction wheels), then why not shape the spacecraft in a way, that it compensate for it? For example: something the same shape on the other side. To make it symethrical.

@MsSomeonenew 5 лет назад

They can just slightly shift the mass and it's balanced without adding any unnecessary parts.

@derauditor5748 4 года назад

@MyBalls my thoughts exactly.

@khajiit92 5 лет назад

with r^4 i think you might be thinking of the expansion of the universe where the energy density of radiation has a 4th power. (3 for the 3 dimensions that are expanding so volume increases + 1 from redshift due to expansiopn of space so the energy decreases).

@dannyhiggs7814 5 лет назад

I really enjoyed this interview. A couple questions came to mind: 1) if alpha particles are hitting the collector, does this not result in a build up of mass inside the collector? If the solar wind is not balanced in terms of charge, i.e. having an appropriate number of electrons, would this not also result in a net increase in the charge of the spacecraft? 2) If the shield needs to be cooled anyway, wouldn't a heat engine suffice? I'm guessing it would introduce additional complexity, but I have to imagine that it would produce all the power you could want, and that it would potentially reduce the radiator size?

@deathpyre 5 лет назад

One thing I am curious with this is... do they have to worry about the solar mass building up inside the cup? Do they have to amplify values because they might be dampened by mass filling the cup?

@JaredSymonds 5 лет назад

Sounds like you need to make a trip to the solar test chamber at MSFC...

@nicksamek12 10 месяцев назад

At 8:00 I think Destin was thinking of radar, it drops off at r^4 because you have to go there and then bounce back.

@adarshyadav8802 3 года назад

Density changes as 1/r^2 I assume that they have used Photon Density=no.of photon/volume (i.e particle flux/speed of light) But interestingly Gravitational force also changes by 1/r^2 Question is Is some how gravity is involve in the Density change of photons?

@AceKaci 3 года назад

Why doesn’t the electric field in the second mesh throw off the magnetometers? Isn’t that generating an electromagnetic field? Is it similar to the reaction wheels, and can be accounted for in equations since it’s a known value? Why didn’t they put the Faraday cup in the center of the shield to keep it symmetrical and reduce torque? Would it have transferred too much heat to the instruments behind it? If so, was there no way to put another smaller shield between it and the other instruments? Would that have made it heavier than the model that was used?

@vennic 5 лет назад

r^4 is a function of resistance of flow through a cylinder based on it's radius, correct?

@rplaughl 5 лет назад

So, basically, they correlate the measurements taken in the corona with the Parker instrument with measurements taken on earth (or near earth) to then be able to predict space weather effects on earth based on future near earth measurements of the sun and its ejections?

@9:17 why not just add another to the other side to have even torque? or just a blank plate made of the same materiel?

@zachell1991 5 лет назад

I guess it adds weight but if it was a blank counter balance(for lack of better word) it seems like it would not add to much weight if it is saving on long term fuel.

@candykanefpv98 5 лет назад

One thing I was curious about is how theyll orient it. What is being used for propulsion to keep it facing the sun (to counteract that torque). I know they said there's going to be a kilo of water on it. Could that be used as mild propulsion since steam expands like a thousand times its volume as water.

@anthonycase 5 лет назад

The water is a closed loop just for cooling. The orientation is accomplished with momentum wheels. (Think about them like this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-5cRb0xvPJ2M.html , but we have multiple wheels and we change the speed of them rather than changing the orientation). Because they're not totally efficient, eventually we have to use thrusters to "spin down" the wheels. So our limiting resource for the spacecraft lifetime is the fuel that our thrusters use.

i don't get why they would not use 2 of those things and get them out on both sides. like this the torque issue disappears and they can have error correction and stuff like telemetry. And don't tell me it's about the cost, because compared to the cost of the full mission it would be fractions.

@johnhartney7576 5 лет назад

How should I go about figuring out which type of engineering to pursue? I like pretty much everything that moves, and I like knowing the exact reason why something happens, or how something works. This is why I think engineering is a good fit for me, but how do I know which type? If you or anyone could offer some insight, I would be so grateful. Also, I am a high school senior and am about to start taking physics.
