- Europe is falling behind in the new space race. Will the Spectrum rocket built by Isar out of Germany, put Europe back on the road to a future in space?
Special thanks to Isar Aerospace and the great artists and editors that bring the future to life.
Special thanks also to Ryan Hansen Space, for his unique artistic talent, and beautiful renderings.

awesome content as always - love the calm and soothing voice - it helps understand complex ideas easily, Thank you!
You should take a look at Rocket Factory Augsburg next
That's a very good idea Jacopo... I'll reach out to them.
Thanks to highlight a small European Start-up. We are at a tipping point in Europe. No time to waste on the European Continent.
Most welcome and very true Roberto!
One of the issues with propane is the Sulphur contaminants. For a disposable rockets, it's no big deal. But for reusable, it helps peopane coke the rocket innards. IDK if it's better or worse than kerosene but it's bad. They said their engine isn't creating soot, so they, may have overcome this.
However, super chilled propane to 100k has near kerosene density and does not need insulation from the liquid oxygen. Meaning the separation bulkhead can be cheaper and simpler. In many ways, its a better fuel than methane if you can get over the problems.
I'm glad to hear someone is trying it.
We are too. The temperature similarity to LOX is certainly helpful. A common metal bulkhead saves a lot of mass over separate tanks. They must refine it to remove the sulfur compounds or it wouldn't burn clean.
@Terran Space Academy
That's what I expect, too. I'd love to know what, if anything, they do about the Sulphur problem. And, if they do nothing, I'd love to know what that does to their engine.
However, I must admit I get my data of propane as a fuel is from a paper that *modeled* what it would be like if super cooled to 100k. Where as the Sulphur data comes from a poorly notationed report on a nasa study; meaning the data is an interpretation of other work, making it a questionable source.
So, take it for what it's worth.
Weather satellites have saved many lives. More power to this company! Sounds like they got a plan. Detecting pirates from space! The mental image I have is the classic sailing ship seen from space.
Two jobs ago, they had propane powered floor buffers, and, after hundreds of hours in use, the spark plug would just be heat discolored...no crud at all.
The more the merrier, as far as going into space is concerned....
That's what we think Scott! Thanks!
Very cool.
Thank you!
I am worried about using propane. I have direct experience using a propane burner on my engine pre-heater which I needed to start the continental engine on my Maule M5 airplane when the temperature dropped below 20 degrees F. It worked well until the temperature dropped to -40 degrees and at -60 degrees it was no longer able to heat anything in its flame. I could literally put my hand directly into the flame at full blast and feel no heat. It is a really tricky fuel at low temperatures. It's going to be interesting to see how they engineer around this fuels shortcomings.
That's an interesting question Dan... When it comes to extreme conditions it's hard to beat space.
How sooty was the burn?
Also being next to a very cold LOX tank ...
Why is starship shown launching with the grid fins extended?
As unintuitive as it sounds, I have repeatedly read that the extended grid fins will not greatly hamper the rocket as it launches as long as they don't articulate during ascent. But that is just what I've read and it doesn't really make sense to me.
He is quite accurate. Keep the grid fins straight on to the flight path and there is hardly any resistance at all.
@@terranspaceacademy
Interesting.
you should spell it like "eesar", that's the idea
I know... Why did English have to go its own way?
@@terranspaceacademy fair enough ;)
awareness is everything...
Great content as always! Thanks ❤
Glad you enjoyed it Doug!
We need another jfk!
We do indeed but not a one on the horizon so far :-) I had hopes for Jr. at one time but of course...
@@terranspaceacademy I have my 👁️ on Ron DeSantis… let’s see what plays
Hmm. The energy density of propane is good, and it is easily compressible to liquid. But that’s for spark ignition engines where it works really well. My old industry was involved in supplying catalytic converters.
But I have no idea how propane would play out as a rocket fuel. Can’t wait to see how this baby performs. We need more launch options.
However I reject the idea that any hydrocarbon launch vehicle can be clean. The higher the performance the more unwanted oxides of nitrogen we get along the outside of the rocket flame where we have high pressures and temperatures.
We think so too... and another fuel option will be interesting to see.
@@terranspaceacademy
Just saw a video on rotating detonation engines. Interesting stuff.
I don't understand.
In a rocket combustion chamber there is no nitrogen. So how could nitrogen oxides be created? Does it happen as a chemical reaction to the exhaust?
@@bmobert
No, but there’s lots in the atmosphere, so while the rocket is below 100 km you will get nitrogen oxide formation.
Lol. The shakeout of small launch outfits has already begun.
Yes it has Luci!
German founded = Engineering Masters are at work, I trust they will have success as that is what it means to be German. They are an awesome people, even though many of their precious Engineering bloodlines were destroyed via world war one and two.
Engineering is not in the blood my friend. It is in the mind, put there by a culture and education system.
@@terranspaceacademy... I just spent so much time consolidating a coherent reply... the app spasmed and somehow cast it all aside befire I could hit send...
My dirty/mixed blood doesn't quite have a specialty(it used to be great at sprinting, more than te average of us jamaican-born who are known for that attribute but was never good at math as the chinese are known for) but every ethnicity certainly does have a specialty.
It's the same as any set of siblings having things that they are all individually skilled in, with mininal training to reach high levels of skill while their brothers and sisterns struggle to match them by committing an exponential amount of effort into catching up, only ro have the distance between them again enlarged with a slight boost of effort from their rival.
I know the Japanese, Germans, South Koreans and several European peoples all have a higher than normal proclivity for innovation~Engineering. It's reflected in world history.
There are, for sure, bloodlines for every conceivable skill, the rest of us just require exponentially more effort to match or surpass the upper limits of those specialized bloodlines.
I can barely type out a response that you can comprehend and it isn't because I am trying to be mysterious or poetic, it's just the noise in my blood that doesn't match perfectly with the structure your blood built into the subroutines of how your mind works.
i think, non reusable rockets do not have a future..
Except for military purposes I would agree :-)
0:51 Not Relativity. Landspace's Zhuque 2 had a perfect first stage burn and made it to space first.
It looks like you are quite right... Thank you Cole.
Honestly kinda weak video man. I mean you could have went into what propane brings to the table. Can it be chilled? Does it coke at all? Max Isp ect. Just showing their promo vid seems like something you should have just linked to.
Thanks for the feedback Rex. I did comment that it burns as clean as methane but has higher density but I could have put in more detail.
I could do without him bitching about what people do with their money. Where does he think that investors come from. ANY space activity, done by any group, even rich people doing tourism, has spin off technology. It is always positive when anyone gets involved in space. He needs to learn that and spread that message without the communism.
Now, now Brian... That's socialism... not Communism :-)
narrator’s tone and timber: warren miller of ski film fame. that’s what we hear
I'll need to look him up Ken :-)
Such an easy question to answer. Maybe
It's the maybe that gets us every time :-)
