How NASA Tests Spacecraft Reentry 

Dude this was on Monday. How did you make this video so quick? I haven't even unpacked yet

Barnard Plasma Systems???

So jealous ya'll got to go on this tour. It looks amazing

I was a human test subject at AMES in a study on exercise for the Mars mission. Got to meet one of the shuttle astronauts. It was a real honor to play a small part of the US space program. Great video!!!

Am i the only one that wants joe to post like 2 hour long videos on his second channel that is him just going down all of his rabbit holes? Itd be like a podcast of someones unhinged science rambles and id love it

The tangents are honestly my favourite thing about this channel now. Makes me not want to skip anything, and the videos are not often crazy long which is perfect

I don’t get why they made this so complicated when they could’ve just made it out of blue tape and hot glue

For anyone who wants to compare the plasma to other very hot things, 30000F is 17000K. For reference the core mantle boundary is up to 4500K, with the inner core being around 5000K. The surface of the sun is 6000K, though the core is 15 million, so we've got a way to go there.

another SLAMMER! also, the obligatory "HELLO" in an echo chamber was absolutely necessary

I really love the final shot out at the wing of your plane, because that wing very likely once had a model in the Ames wind tunnel

woah is that Tim Dodd the everyday astronaut

God that footage of the ablation is so cool looking.

"Is it between 200 and 2000 per hour?" "You're... _way_ off" 😂😂

I was and still am a CFD engineer from my master's thesis until now and no CFD will never 100% replace real testing for everything. It does and has already replaced wind tunnels within F-1 because we have 10000x the number of real windtunnel tests compared to the number of simulations that are being done. The regime that those vehicle operate in are very restricted and through regulation they are not set to start operating another 100 mph faster anytime soon so because the operational domain is very refined and so very well studied experimentally it will be years before CFD catches up to account for all of the simulation backed phenomena just in the boundary layers alone.

Joe: “I test my heat-shield with a very hot blow torch“. NASA Ames: “Hold my beer”. No shade, Jon, but wow. I drive by that facility occasionally, and often wish I could get a glimpse inside. Thanks for taking us there.

Tim, Joe and Scott are legendary.

9:35 thank you for putting potential embarrassment on the line and getting that audio clip for us!

It should be mandatory when you get a bunch of RU-vidrs together for something like this that, at some point, you all stand in a circle and film each other filming each other.

8:50 oh god PLEASE go on every single tangent, I LOVE your tangents

Lots of familiar faces in that crowd. Man, that footage from the arc jet is nuts.

omg Joey is going to take his milk carbonating to a whole new level with this technology!

Glad to see Hanger 1 going back together. As a high school student I trained at NASA Ames Research Center for machining and design. Later my first duty station in the U.S. Navy was VP-31 Staff in Hanger 1. Got to climb all over it, even opened the top hatch and sat on top of the hanger for a Blue Angels airshow. Good times. Once I put in a Request Chit to "Paint the hanger a light golden brown, so as to disguise it as a giant twinkie from the air". Oddly my request was summarily denied.

🤩🤩🤩 So damn cool! Looking forward to your plasma experiments too!

The slightly different focus on the details in the arc jet system, modelling the engine, and going into the wind tunnel tech at the facility was super cool. Can't wait to see others' videos for more details and I hope more videos like this get to happen in the future! Just the right amount of rabbit holes and the writing is great. And the video shots are entertaining. More waves at perfect optics plz!

I found you because of Mark Rober. My dad worked in New Orleans for the Apollo rockets and then the External Fuel tank for many years each time. He is now 83. Thank you!

Legit you need to make a down-the-rabbit-hole channel to talk about all the different tangents. You've got so many people geeking out about this

Joe Barnard, Tim Dodd, Scott Manley, Tibees, and more! What an awesome group of people!

I've been a longtime viewer, and I want to thank you for the amazing content. It's been a true pleasure watching you puzzle everything out, and I can't wait to see where this journey leads... perhaps to the stars?

What a cool video of the awesome stuff going on around Ames! NASA definitely deserves the recognition for the amazing technology work they do outside of the high-profile flagship programs.

This is what I'm here for! Excellent STEM content and a damn good watch! Thanks, dude!

I'm glad YT suggested this after Scott's video. Well presented and it was nice to hear a different perspective.

I absolutely love this video. Having multiple YT folks talking about different parts of the same topic gives so much more insight. Everybody seems to take different views on the same topic. Thanks for sharing!

It is crazy how much you have learned about aerospace in the years watching your channel. I have studied, and worked on airplanes, rockets, avionics systems, piloted, and I'm certified. I feel you mastered Astronautical engineering way more did I ever did, very inspiring. Definitely recommend getting your degree trust me. You don't want to be another Chuck Yeager.

Thank you for letting us tag along in our own way. These are the kinds of videos that would have gotten me interested in STEM as a kid, and keeps my love of learning going as an adult.

Hey Joe, Thank you for making these videos. As someone who is not really in a situation that allows me to do what you do with rockets, I think it's awesome to see you grow step by step, and to learn what you have learned. You're a great communicator, and I can only imagine what the future will bring.

One of the fire channels I watch every single video on without skipping a second. Incredible content, great visuals, impeccable explanations. Honestly I would watch you down every rabbit hole you could imagine because the information your provide is invaluable

My plane did a flyaround before landing at SFO on my way to open sauce, and I saw this huge cool facility out my window. I knew from the shape of the buildings this was something special so I snapped a pic. Watching this vid I suddenly remembered the picture and sure enough, that's Ames! These sorts of facilities are among the coolest places on the planet, thank you so much for sharing your tour with us!

Thanks for keep feding my brain with awesome science, beautiful pictures, ideas to think about, problems to dig in, food to make plans about what to do if there is more time again, ideas for little projects, reminding me again and again why I love science and creating stuff

I'm so glad you decided to share this. It feels like something I'd never have been able to see on my own.

I will always be rooting for this project from Sweden! Good luck, seriously amazing stuff

Joel, your channel is special. That humble thank you is icing on a rocket fuel cake. Keep it up, man. We are all in.

I live just up the road from Ames and it is so interesting to finally see some of the science and engineering that goes on inside.

Awesome. Thank you for sharing. As to your thoughts on RU-vid - as long as creators such as yourself are documenting things they do and are excited/passionate about there will be an audience such as myself who will Watch, Learn, & Enjoy. Blessings & glad you got to do both OpenSauce and this trip in particular.

This was GREAT!!! In watching Formula 1, I know they fluid dynamics and wind tunnel testing during development but you mentioned the "oil" option which sounds like the flow-vis paint they spray on the cars (along with aero-rakes) to do live on-track airflow testing. Thanks for sharing your trip!

Honestly i have a hard time beliving you managed to increase you video production rate so much, and i'm really greatful for every high quality video you make, thank you so much!

commenting to support... really enjoyed this video and hope you make more like it (if you want!)... love all your videos!

Thank you Joe. What you've built and achieved with this youtube channel is a true inspiration.

Thank YOU for your videos like this and all of them. I'm not educated enough to do the things you do, but it fascinates me. I've been watching for what feels like years, and I truly value the work you do on them.

Been waiting for this drop since Scott Manley's video a few days ago. Excited to see your perspective and how it pertains to your space shot.

Dude, I've been watching this channel since you were in Nashville, you're killing it! It's crazy to me that this channel doesn't have >1Million subs yet!

Thank you for persisting and sharing your hopes and dreams with all of us. I am living vicariously thru your videos. I had hoped i would work at JPL someday but life happens. May God bless your efforts and your space spot be an amazing success.

What a great video companion to your previous work and to Scott's! Really loved this episode and appreciate all the hard work to make this "non-standard" video and your taking your time away from the space shot to do this!

That was super cool, like the entire thing, but especially from 4:33 onwards. Absolute "science-fiction in reality" vibe. Thank you!

Thanks for bringing us along Joe!

Originally became a fan because of the trying to land a model rocket series, but now I'm just here for the ride. Loving all the videos you're putting out 💪

You area amazing Joe, I love all of your videos, you deserve all because the hard work you put in your projects

Nice look inside Ames. Fascinating work happens there with a long history.

Way cool. Glad you could share this with us.

We need a longer video 😂 so many things I want to know more about. Could do with a whole series branching from this video!!!! NEED MORE

Amazon Joe! Nice, love the content as usual! I appreciate you!

This stuff is so cool! Thanks for making it! WRT to the Apollo ablator, a different, also very ITAR government lab had a hard time re-making a crazy material called 'fogbank'. Probably not gonna get a fun tour and video from them about it though.

I got to do some research project at AMES about 10 years ago. Really wish I could have toured around all the facilities like you did. Those wind tunnels are massive up close.

thank you for doing your youtube channel. One of my most favorite places on the internet. Greetings from the Netherlands

I enjoyed that, thank you, like being back at work 30 years ago at the Royal Aerospace Establishment Farnborough.

You are such a joy to watch. Thank you for sharing your journeys with me. :)

thanks for making videos they are a pleasure to watch, its nice watching videos of people who have real passion in things

One heck of a tidbit, thanks for sharing! And also that kegular cameo at the end 😎

ngl I was expecting "I'm Joe Barnard, Fly Safe" at the end

We will never get bored of your content Joe! Keep up the good work!

Mind-blowing experience, I felt like I was there, thank you for this "different" video, made as usual with passion!!!

Phwoaar. Someone turned an old Skool Mac into a robot. So awesome! Thanks for sharing this with us Joe. I'm loving the extra side tracks !

It was an honor to partake in NASA's NCAS program at Ames Research Center earlier this year and it was honestly really exciting to revisit what I saw in-person through this video!

Thank you, we are studying reentry in Australia and always wanted to see inside Ames :D

My father worked at AMES, he never told me the top speed. Amazing footage, you earned a follow..

super cool! love these types of factory/equipment tour videos

Oil testing is actually still used alot with f1 cars. Due to the regulations they have limited windtunnel time so during testing they add "flow viz paint" to the car to see how the air flows around while driving.

Your videos are very inspiring. Thank you Joseph!

Thank you. Your Videos are informative, entertaining and just awesome. this is peak youtube!

Cool video. A nice change of pace. Although I have been enjoying your other videos even if they are way over my head.

Youve been making some bangers recently. Loving it

Thank you for making amazing content and for pushing the boundaries of your own technical knowledge and capabilities. Also, there is no rabbit hole too deep for us. Post more tangent videos.

Excellent video !!! ... Your progress as a creator / explainer / maker over the past recent years / months has been a pleasure to watch / experience. Keep up the great work, and feel free to yell down research tunnels every time it feels like the right thing to do.

I definitely found this video interesting, thank you for making it!

Thank you Joe for making videos so many of us enjoy!

Would love to see more little videos like this between the "big" ones! Your passion is contagious :)

You're such a good science communicator! A couple of years ago, I knew absolutely nothing about rockets. Now, I nod in agreement when you talk about foldable heat shields and ablating materials. What a journey! Thank you! (edit for typos)

Wow, i do like this recent more of a, non project format about various neat aerospace stuff, CFD, HS, and this one are really cool to watch

4:33 that is one of the coolest spooling-up sounds i have ever heard

THX for making content that ist right at the top of my daily evening dose of space news. Together with Tim and Scott. Top notch "Entertainment".

the oil flow (or equivalent) is used in formula one racing cars. You usually can see it on the practice "one" (and mostly in the beginning of the season) . They apply it to the edges of the car and after one or two lap they bring the car in the garage and look at the flow of the air.

hey. I am not a patreon supporter, just a long time lurker. I got a little teary in the eyes at the end, just wanted to say it's been a pleasure to watch you living the dream. Wish you the best future possible. Stay wicked

I really enjoyed this and all of your other videos. Thank you!

Glad to see this on the main channel. This is a really cool topic.

Every video of yours is a 10/10. Great stuff!

Amazing video! Thank you for your effort and dedication! :)

Thanks to you and your great content!

this stuff looks so cool. glad you got to film it :D

I don't think we will ever get bored with the videos you do, Joe. Keep 'em coming!!! 🙂

I had goosebumps from the images of nasa facilities. Thank you!

Love your videos bois. Thank you. Please keep ‘em comin.
