NASA Set Its Spaceship on Fire. Here's Why

I really like the interviews with experts. Especially liked how he laughed about asking a scientist if he thinks more research should be done! :))

I am a former submariner - I remember reading long ago that a simple class A fire would raise the pressure in the submarine by a significant amount, raising the problem of harmful gases as the partical pressure increases. Additionally, I would have been very interested in hearing about the procedures for fighting electrical fires (on a sub it starts with dropping electrical power - which can have some adverse consequences if critical systems abruptly lose power). I would really like to hear how the plans to combat these types of fire. Additionally - are spacecraft built to preclude class B and class D fires? If not, how are they countered?

I love that this channel consistently produces great content. There's some channels that I have to watch almost daily and this is definitely one of them.

You didn't ask the most important sci-fi question: Can you put out a fire by partially venting the compartment to space while maintaining enough pressure that any depressurization injuries to people are probably survivable?

That whole inverse flame thing, I’ve found very interesting for some time now since watching a video of someone creating a methane environment inside a sealed chamber then piping in a tiny stream of O2 and burning it. It blew my mind and I’ve wanted to try it out ever since..

It really is the early days of space exploration. Amazing

i thought the easiest solution to larger fires in space would be to evacuate the section with the fire, and use the one thing you have in abundance in space vaccum and vent the atmosphere in that section for a short time before represurising. yes it would waste a small ammount of air and the outgassing would would redirect the spacecraft unless some sort of bi-directional outlet was used to ensure that any thrust from outgassing was automatically counteracted in the oposite direction. an emergency backup supply of replacement air might be the more space efficient than any other fire supression system and it would be always be great to have a larger emergency backup supply of oxigen.

🔥 Great scoop! Nobody covered this news. Well done!

Thanks for not "dumbing down" the content. I always enjoy these technical conversations with leading experts.

I’ve worked for an LP company as a service tech for approximately 26 years now and have been dispatched to and been party to many an emergency there in. I find fire both beautiful, awesome, hypnotic, as well as exceedingly humbling and potentially terrifying! It’s both something that’s awe inspiring and obviously utilitarian, as well as something to absolutely be respected and revered. Fire in space is next level and I’m delighted and encouraged to find we are actively investing into this and hopefully producing mitigation tactics, techniques, and technologies gearing up for its eventuality…

Many years ago a guy experimenting with liquid nitrogen stuck a pipe in and pulled it out. He noticed it hummed so he recorded it. Later while playing the hum near the now warm pipe it began to chill to very low temps -- using sound alone. Consider this as an alternative to the normal Fire Triangle suppression methods where o e removes the heat from the combustion using a sonic method. A method that untroduces no debris. Id try that on the ground then in space too. Also it should be easy to store super chilled liquids in space as one need only expose it to shadow in space. But the sonic chill is most fascinating. Try it.

That's the kind of next level thinking I love. Thanks for being the communicator of all this information to us simpletons, Fraser. You are one hell of an important human being. Thank you, thank you very much And Thank you to all the folks doing the work that is so very important, but so very underrated. The silent heroes of science and engineering. I salute you

If I remember correctly, the Russian space station, Mir, had an unplanned fire experiment 😀

A very interesting subject! Thanx Frasier!

A great job by Fraser to pull the information out of the scientist about his expertise. Thank you for being such an advocate for the listeners as some guests are much more ready to share a particular message where in this interview Fraser is doing a lot of the heavy, lifting to keep the information flowing. Fantastic job! Don’t get me wrong the information was super fascinating, but just not as forthcoming as others .

Super informative and very happy they got to pull the experiments off. Can't wait to see what they can test next. Fire is VERY environment dependent.

I have attended both shipboard firefighting and aircraft firefighting schools while on active duty in the USN. Thank you for this interview. ( thank you for ALL of your interviews!)

What about the Mir fire? “On Feb. 24, 1997, the six crew members aboard the Russian space station Mir faced significant danger when a fire ignited in an oxygen generating system. The searing flame, lasting several minutes, not only cut off access to one of the two Soyuz escape vehicles but also filled the station’s modules with smoke….”

I couldn't pass this up, my inner Beavis came out when I saw FIRE FIRE FIRE

Thanks for a very informative article .
