@lrocket I really liked the episode, and like the Impulse vision.

mainenginecutoff.com/podcast/324 I had a great conversation with Anthony on the MECO podcast

@mechanical_4u Notice the red part on the left and inside the nozzle. Red is bad. That could be running to hot - on a mixture too close to stoichiometric - or it could be not enough flow. The parts that were too hot lost strength and the nozzle blew apart.

Why does an engine "explode" if it doesn't receive fuel properly?🤔

@zupet0 I pretty much always have something I'm working on, so yes, there is something coming. I wouldn't say "coming soon".

@eager_space any youtube coming ? 😃

I've been looking at SpaceX's stargaze and am very impressed. They use video from the star trackers on all 10,000 starlink satellites to track orbital debris with low latency AND they decided to let others hook into the system for free. That is a very big deal.

@Space_Horton @DJSnM @robertoblake I thought that audience capture was illegal under the Geneva conventions... And I don't have much room for guests in my house...

@eager_space @DJSnM @robertoblake But you are guilty of audience capture too - I can state that as a member of your audience we demand clear and rational analysis and you keep providing it ! :)

Some Creators really are captured by the audience and I feel so bad for them. Imagine truly worrying about and having your business held hostage by people who will scrutinize your business and who and what you spend on and call you cheap or greedy… As they simultaneously think paying $8-$19 a month to watch Ad Free unlimited content is too much… Or expect you to spend 50-80% of your income back into giving them high quality free content… that they watch with AdBlock, and if you can’t manage they will say you shouldn’t make content and should “get a real job”. Mostly this is the plight of entertainment channels and channels with younger audiences . Grateful everyday that I really mostly deal with adults… even though once and awhile someone will show age doesn’t equal maturity…

@Orbital_Perigee "Trades" are never a general statement - they are all in reference to a specific mission and a specific vehicle. You can't do trades without the specifics.

@RazikeF @DJSnM @robertoblake Thanks. I like to go into more depth because that's what makes it interesting for me.

@eager_space @DJSnM @robertoblake Love your work. Very informative especially about specific impulse and different isp

Maybe? I spent some time flying an RC helicopter and got skilled enough to hover, so if I need to get to 10' and come back down, probably. Unlikely I can actually get it started...

@DJSnM @robertoblake I as well... I'm just happy that I'm not trying to make a living here and can make a whole video on specific impulse if I want.

@robertoblake I regularly feel conflicted about doing content I want to do, but the audience may not care about. But I really don't want to be the guy that talks about rocket explosions and nothing else.

@szetoinsitu @SummersJohns69 There is certainly speculation in that area.

@SummersJohns69 @eager_space Any earth facing cameras like DSP?

@DJSnM I predict that Blue will be able to obtain all future New Shepard licenses with no delays...

I’m amused that the FAA press release about transitioning to the new launch licensing system leads with New Shepard

@Robotbeat It's not that. Electric cars worked because people could charge them at home or at work - they plugged into (ha ha) existing infrastructure. There are 54 hydrogen stations in the US and Canada, and none of them support this fueling approach. Why would anybody build more?

I don't think pepole realize just how little range one of those canisters provides. And how just bloody expensive this would be. Go look up the price per kg (gallon of gasoline equivalent) hydrogen is in California right now.

@Wisdom_HQ There are commercial hydrogen fuel cell cars out there. In the US and canada, there are 54 stations where you can fuel them. And this requires a new form factor. Where will you drive it? Electric battery cars could charge (slowly) in many places right away. 92,000 chargers...

hydrogen Powered Car, 1,500 km range with a 5-second refill… sounds illegal.

@peterrhague @Robotbeat Or methanol. Or Jet A. All of those fit into existing infrastructure.

@Robotbeat If someone gave me a free, carbon neutral supply of hydrogen today, my first instinct would be to use it as a feedstock to make more practical fuels eg methane. It’s just not a good energy store.

@TechSpatiales @brickmack Sorry I wasn't clear. Deorbit is easy in LEO, graveyard is easy in MEO.

@eager_space @brickmack There is no graveyard orbit in LEO

Dans le sens contraire de la tendance mondiale, la FAA vient de supprimer la régulation qui oblige les lanceurs US à désorbiter leurs étages supérieurs après usage, qui les forçait jusque là à retomber sur Terre sous 25 ans. La FAA autorise donc davantage de débris sur orbite.

@peterrhague @verdur_in The apple II and TRS-80 were released in 1977 when I was 13. The TRS-80 was $600 and the Apple II was $1300. That was with 4KB of memory and cassette storage. In 1977 you could buy a chevette or pinto for $3000. I knew *one guy* in high school who had a TRS-80.

@verdur_in At the risk of over flexing, I believe I was on to 6502 assembly language at that point

Is this supposed to be impressive? A generation of us were brought up to code in BASIC at the age of 7.

@nealmohan @YouTubeCreators This is actually pretty cool as I no longer have to downsize my thumbnails.

Exciting news: as of this week, all @youtubecreators can now upload 50MB thumbnails (up from 2MB). Now, your super high-resolution thumbnails will look epic on TV 📺

@brickmack @TechSpatiales MEO - like LEO - is okay as long as you hit the graveyard orbits. There's lots of space up there and not many satellites right now. GTO is where you really want disposal. They *do* reenter eventually but they have some really annoying orbits like 200km x 10000km first.

@TechSpatiales This was never actually a regulation, just a proposal, but most American launches have still done this for decades by convention. Its just difficult to achieve 100% coverage, because some orbits (particularly MEO) take a lot of energy to dispose from

@DJSnM @dpoddolphinpro Okay... Which was sillier... ARCAspace or SpinLaunch?

@dpoddolphinpro I remember the rebuttal video when they complained I had overestimated their performance.

ARCAspace, the water rocket company which blamed a Scott Manley video for a lack of investors, might not be doing so well. All of the websites associated with the company are showing Wix unconnected domain pages. RIP?
