Guess they should have been either a bit less graditum, or a bit more open about what they actually have at the moment.

Propellant Recycling
.50calBMG replied to Cheif Operations Director's topic in Science & Spaceflight
No, if you don't let any exhaust escape, you won't get any net thrust. Like what was said earlier, pulling up on your own shoe laces doesn't lift you off the ground, in the same way that blowing into a balloon doesn't move you forward because none of the air escapes to produce thrust. You effectively must lose something to gain something, in this case it's propellant for thrust. Nothing is ever free according to physics. -
So, I guess we can officially say raptor is the highest chamber pressure engine to ever fly now... Is anybody else vibrating with excitement?
-
I don't know, I wouldn't think a blowoff valve would pulse like that
-
I don't think so, I believe Ariane 5 was flying before the 5m Atlas V was flying. I guess they could have bought it from Arianespace, but I doubt that because Ariane probably uses them more often.

totm dec 2019 Russian Launch and Mission Thread
.50calBMG replied to tater's topic in Science & Spaceflight
Is it bad if I had to think about it? </S> -
Dang, was really hoping she could get that mythical 100%. Vega has always been my favorite ESA launcher.
-
Man, that's unfortunate. How many more flights did the original Vega have before Vega c replaced it?

[1.7.2] KK Launchers - Delta, Atlas Pack
.50calBMG replied to Kartoffelkuchen's topic in KSP1 Mod Releases
It doesn't need a separator between it and the kick stage, I didn't see an ejection force on it? It tried to spin the entire second stage along with it. I should mention that I am using 1.6.1, so maybe the breaking ground expansion adds some plugins to the stock game that I just don't have. -
[1.7.2] KK Launchers - Delta, Atlas Pack
.50calBMG replied to Kartoffelkuchen's topic in KSP1 Mod Releases
Is there a dependency for the turntable to actually spin or am I just using it wrong? -
Huh, never seen that happen on other launches before, but makes sense. I almost thought they blew a nozzle out like ATK did a few weeks back.
-
Anyone else wondering what all those little flecks were that came out just before booster sep? Looked like the right side booster flashed a bit as it happened too.

Should our next crewed landings be on Mars or the Moon?
.50calBMG replied to a topic in Science & Spaceflight
Only problems with your logic is that the moon is much easier to get to, and at certain times Mars is far more dangerous, like the EDL phase, or the journey there. I agree that Mars is humanities future, but we just aren't ready yet. We can easily set something up on the moon at this point, but we don't have the experience in landing anything larger than the curiosity rover on Mars yet, so it is a good idea to take baby steps for now.- 30 replies

Which we still haven't gotten our footage that we were promised

Well, better to get the failures out when they are on the ground rather than in flight, I guess.

How exactly do leading edge extensions cause more drag?
.50calBMG replied to Schwarz's topic in Science & Spaceflight
I would assume your guesses are correct, but I would also add to that the larger surface area also creates more induced drag because of the extra lift provided, as well as some frictional drag from the increased surface area. -
@sevenperforce... You are smarter than me.

Can't wait to see if they give us a reentry video like eft-1 had.
