We don't describe color, we measure it. Red light typically has a wavelength of 625-750 nm, so however an individual perceives it, red is still red.

Given that the partial pressure of water vapor goes up as temperature rises, the overall effects can be quite dramatic as it gets hotter

The engines did not exactly fail. They were prematurely shut down, presumably for out-of-parameter sensor readings. It’s quite possible those engines could still fly after relatively minor repairs (if any). Edit: after further thought, if they all shutdown at the same moment, it's possible it was more of a plumbing issue, trying to feed so many engines. This is why they test. The ultimate test is flight, and in a hardware rich environment flying can be less expensive and provide more useful data than building a full-duration test stand (which would need to be stupidly robust to withstand the fury of a full-duration SH static fire).

The bypass fan moves more air for more thrust. It's essentially a ducted fan powered by a combustion turbine, and is more efficient than only using the hot, fast exhaust stream for thrust (move a large amount of air at a slower speed, or use a smaller amount of hot gas moving very fast). Fast-moving gas is LOUD, so large turbofans (fan air carefully blended with the exhaust stream) are a huge help with noise abatement around airports.

The scenario is reminiscent of Niven's "Known Universe" chronology where demonstrating a 'planet-buster' technology was an effective way of deterring a highly aggressive species. But deploying a planet-buster isn't nearly as effective in Star Wars, for various reasons.

It occurs to me that global thermonuclear war just might have the side effect of combating global warming, destroying the fossil-fuel infrastructure responsible for it and cooling the planet with the so-called "nuclear winter." The survivors would then build back clean, green, and glowing. Obviously, this is not an optimal solution, but human nature being what it is...

I still think "Orion Rising" would make a great name for a movie...

The star forts were built to withstand cannon fire, with walls backed by earth. The star shape and sloped walls are to deflect cannonballs instead of having to withstand the full impact. The star shape also allows the entrances to be placed where attackers would face a withering crossfire if they tried to breach it

Jeb's favorite song, along with "Light my Fire" by The Doors

And vested interests are scared…

You know, I could see that working. “Dangit, I landed on ‘RUD: return to VAB or use a “Revert to launch” card’” or vice versa

Robbie's gone somewhere down that crazy river...

Not sure, but I think spacescifi has made a thread or two about it. We need the hot superconductor for the cold fusion reactor to power the emdrive…

Love the "space tape" holding all those little conduits/hoses/lines in place

Creepy. My question would be "Was there a house there 100 years ago? Nothing spooky has happened to me, but a friend shared a story about when he and a girlfriend got spooked after sunset in Stanley Park, a place where many bodies have been found, and surely many many more remain unfound.

Tuned in and all the fog had me wondering if I missed something...

Excellent article that explains a lot. What I get out of that article is that the process depends entirely on luck (aka random chance) to get the right atoms in the right places in the crystals. Maybe if they can figure out the exact configuration that is superconducting, they can nano-print it. That would be game-changing, for sure.

I didn't think they did testing on weekends...

Probably just the outer insulation, if the tanks are even in service

Oh, they probably just used the DSN to blast out a much more powerful signal than usual, strong enough for Vger to detect. Meanwhile, in about fifty thousand years an alien civilization will pick up a mysterious signal that, when finally decoded, will amount to “Turn left!”

Sure, let’s put this here…

I enjoyed working almost under the approach corridor to YVR, seeing them lined up 5 back while outside on smoke breaks

Reminds me of air cadet summer camp, but I’m sure the servicemen here have heard worse. Best was when they cranked up “Danger Zone”

I think it’s part of the Cascades? The peak in the background is Mt Slesse, which has been a favourite target of mine in this thread.

Except it shows a FH to reach HEO, which needs to be crew-rated
