Space Simulation Chamber - It's more than just creating a Vacuum.

Before a spacecraft can be launched into space it must go through a battery of test. The most important ones are performed inside a space simulation chamber. These chambers replicate the conditions of space as much as possible. In this episode I discuses what these chambers are and how they work.

CORRECTION: at 12:00 The reason for the bias trajectory is to prevent the LAUNCH VEHICLE from crashing into the target planet. It's not about the spacecraft crashing into the planet if control is lost as stated in the video. The launch vehicle can't be sterilized for obvious reason. So once the spacecraft (which is sterilized) separates from the launch vehicle, its trajectory will be corrected towards the target planet. Here is a correction stated in my other video on the subject: kzbin.info/www/bejne/hXiUmXqiesyEnpo Sorry about the error.

[@Astronetics]

This is the most comprehensive video I've seen on prelaunch spacecraft testing. Bravo sir!

[@GravityBunk]

I’m designing one of those t-vac chambers, so excited.

[@AnupamVipul]

This video was very calm and wise AND I like it

[@ReflectiveLayerFilm]

Awesome. Thanks

[@Muonium1]

I was thinking about the cassini camera haze issue, and then you said it! 😉 I remember when it happened and I was very worried, but then they turned on a heater and it disappeared in a few weeks.

[@ReflectiveLayerFilm]

Yeah, I'm always amazed how little things can potentially harm these million or billion dollar missions. I'm so worried about James Webb. From launch to deployment.

[@Muonium1]

@@ReflectiveLayerFilm oh yes, up to $10 billion now. if that rube-goldberg monster actually launches to the L2 without exploding, opens like a Japanese origami crane, deploys and aligns all of its optics, AND actually starts taking data....well I'll eat my hat! Delayed again I heard because of the shutdown, probably until 2022, so we're still on that same asymptotic curve approaching launch! lol

[@mete3254]

perfect presentation

[@user-bl1pw2th4l]

So informative! This is what KZbin should be for and millions of people should be invested in learning this knowledge and propping up people like you, David Butler, Nick Lucid etc

[@ReflectiveLayerFilm]

Thanks a lot. Really appreciate your comment.

[@mrmadmaxalot]

I just stumbled on this channel via a recommendation and have now watched several episodes. This is a perfect example of hidden gold on KZbin. I am happy to be a new subscriber here. This is great stuff!

[@ReflectiveLayerFilm]

Awesome, thank you and welcome to Reflective Layer.

[@americancolor2]

great work. keep the good work bro.

Unforgiven? ISS Completed its 150000th rotation around earth and just hit by 2mm meteorite in 20 years. There are 800 hundred satellites revolving around us 20 or more years. No refuel, no coolant change, no malfunction, no battery change, geostationary mylar shielded aluminum satellites are under constant sun solar radiation in infinite vacuum and nothing happens. and they are working like a clock in space equilubrium. So what I learned from space missions everything works perfectly in space than it works on earth. Most of the accidents happen on earth but when something reach ELO or beyond, all simulations work perfectly. What I learned from space agencies, space is the most peaceful environment for machinery and electronics.❤

[@Joules120]

Beautiful. Thanks!

[@ReflectiveLayerFilm]

Glad you like it!

[@martinromano99]

My god, your channel is amazing.. I've just discovered it

[@ReflectiveLayerFilm]

Welcome aboard!

[@procactus9109]

Cool

[@LearningCurveScience]

Cool video, You explain things very well, and I love your animations, they really help to visualise what's going on.

[@ReflectiveLayerFilm]

Thanks. They also help be visualize what's going on. Sometimes after reading the relevant paper I still don't fully grasp it until a create the simulation.

[@kamikatze42]

Your videos are awesome and I wish you the best of luck for a breakthrough!

[@ReflectiveLayerFilm]

Thank you. I really appreciate your comment.

[@Digimer]

That was fascinating, and well produced. Subbed, and very much looking forward to future videos! Thought of doing a deeper dive into the five mission categories?

[@ReflectiveLayerFilm]

Thanks for the sub! Interesting you asked about the mission categories. The script for the the 5 categories was originally longer but then I checked the total time of the video. Something had to give. So that part got the axe. Doing a video for just those 5 categories is a good idea. That's on my list videos to do.

[@qwertyuuytrewq825]

It is even painful to think about how many things need to be considered and scheduled to make a spacecraft ) This looks like a very stressful job. Great video. Thank you!

[@ReflectiveLayerFilm]

When logistics is added, complexity definitely goes through the roof.

[@malakiblunt]

for the algorithm

[@slimwagz946]

All I heard was "we have to attain a perfectly controlled environment" as it pertains to recreating a completely randomly chaotic environment, everything in science is always "eh, close enough to justify telling people this is why and how..." to only learn a tiny bit disproportionately later contradicting or falsifying the exploitation... I mean explanation although still not conclusively explaining it to any degree of which they tell us will significantly change what we know and how to use that knowledge in applying it to our real everyday lifeback here on Erf

[@dwayneam]

Ah ... there is no sound in the vacuum of space.

[@JerryDougherty]

I would suggest that your statement that the vibration and acoustical environment from launch is easy to simulate is very misleading. While it may be true that we can reproduce the environment the characterization of the anticipated environment is extremely challenging to calculate.

[@ReflectiveLayerFilm]

Thanks for the response. I wasn't suggesting that it's easy. I was comparing it to the difficulty of creating the other environments which can not be easily reproduce and require very expensive single use specialized devices. That's why I stated that it was relatively easy. All of these artificial environment will have to be tested and verified against the real thing. The acoustical launch environment is the only one that can be verified without having to actual go into space. I'd agree that every aspect of testing and certifying a spacecraft is difficult because if nothing else, the operating margins are thin compared to other vehicles.

[@JerryDougherty]

@@ReflectiveLayerFilm I enjoyed the video and while I would agree that vacuum chambers and the testing that must be performed is challenging and resource intensive, giant shaker tables and acoustical chambers have their difficulties as well. So yes it's all pretty involved and each step in the process is critical to ensuring the best chances for success!!
