The Delta IV rocket is one of the two rockets that came from the Evolved Expendable Launch Vehicle program (aka "If Boeing and Lockheed Martin won't stop suing each other, we'll make them work together!")

For those not familiar with rocket science, the simple way to increase payload mass is to use more rocket to lift it. The first stage of the Delta IV is called the Common Booster Core.


The Delta IV has variants that use anywhere from 1 to 5 strap-on solid rocket boosters to boost larger mass payloads to orbit. Here's one with two solid rockets


In its largest form, the Delta IV heavy leaves those boosters behind and simply uses 3 Common Booster Cores. The outside ones run at full throttle and the center one is throttled down to conserve fuel for when the weight of the extra two boosters has been thrown off.


In its Heavy configuration, the Delta IV prepares for launch by, at T-7, purging and cooling the engines with a burst of hydrogen fuel (going from cryogenic to gaseous takes a huge amount of energy and cools everything around it.)

This leaves the problem of a massive cloud of hydrogen gas around the rocket; the gas is ...


Promptly


Burned



Off


The orange paint on the fuel tanks is formulated to attract free hydrogen in the atmosphere and to hold it there burning in a controlled manner rather than risk forming bubbles or pockets of hydrogen in the atmosphere that could explode.

The rocket is supposed to be on fire. It's a safety feature.

With what may be the final flight of the Delta IV Heavy nearing, I urge all of you to watch the test flight and reentry of the Orion Module on December 4 (check the Spaceflight megathread in Sciences, Academics, and Languages for further info.)

Rally racing isn't like track racing where you can sit in the stands and watch. Most of the time the fans stand dangerously close to the track and watch. Sometimes, something goes horribly wrong and they're more than willing to jump in and help ...

Co-drivers also sometimes call out what gear the driver should be in for a turn, so if you hear something like "100 left 5" it means there's a left turn coming up and the driver should be in 5th gear.

When that privately funded one-way trip to Mars got announced, the first cut of candidates was 1058 out of over 200,000 applications. Even accounting for joke applications, there's still tens of thousands of people who are totally willing to abandon their lives on Earth and spend the rest of their days traveling through space and living in a tiny settlement on Mars.
And most of them are people you wouldn't want to take an hour car ride with, nevermind a one-way trip to Mars.

I will never get tired of SR-71 stories
My dad was in the Air Force during (what I'm 99% sure from his story, his deployment records, and the rough timeline,) was the USS Pueblo incident. I forget whether he was in Alaska or Japan at the time, but they scrambled an SR-71 to get pictures fast. He said they had pans under it on the runway to catch the dripping fuel, it flew in the opposite direction of NK in a steep climb to get to altitude and warm up the skin, refueled out there, then turned around. He could barely turn his head fast enough to follow it when they spotted it coming toward the base, and it was over the horizon by the time the sonic boom hit the ground.

I don't know what kind of things he knew and saw that he couldn't tell me from his time in the Air Force, but I do know that they posted two armed guards in the room when he had his appendix removed to get everyone out of the hospital room in case he started talking when recovering from general aneasthesia (his brother said they had orders to shoot everyone in the room, but I think that's wildly exaggerated.)

edit: he worked in intelligence, said that he worked with TS-SCI information, and did tell me that he knew things he would never be allowed to say to another person as long as he lived. As a teenager I took great joy in annoying him by saying he worked on the aliens at Area 51.

I, too hate other people that have fun in ways I didn't vote for. drat skate kits! Get Offa my grass!

Serious bit: I unicycled in my youth, before I got a serious road bicycle. It was fun to try and learn and develop new ways of balance that I didn't know existed in my brain stem before I tried. That trickled down to balanced stops in cycling and leaping gracefully in racquetball and not falling down during sex in ways I hadn't imagined.

And unicycling distances and sometimes backwards gave me a purty butt.

Unfortunately, it was all before this new-fangled age of freewheeedl and braked unicycles that exist now (drat new-age hippy helmet-wearing kids!).

Also unfortunate, and I'll give you this: it is hard to not look like a pogo stick riding doofus when riding a unicycle on normal terrain, cause balance on a pogo stick with a wheel on the end is kinda hard (sans circus soleil, which did not like my purty butt so much).

But it's also hard to not look like a pogo stick riding doofus wearing a propeller hat when criticizing other people having fun.

So there.

I always thought Sinatra was a shithead because how he treated his wives and was a mob-adjacent rear end in a top hat. Turns out he was a dynamic person with both good and bad.
According to his son, he almost certainly suffered from untreated bipolar disorder, which complicated things.

He also went from supporting a socialist, Henry Wallace when he was young to being a staunch Regan supporter as he got older. :shrug:
The tipping point seemed to be when he expected to host JFK's inauguration considering what good friends they were (hanging out, sleeping around, etc.) but the FBI didn't allow it because of the mob connections and the White House went with Bing Crosby. Frankie rampaged through the venue, smashing the new decorations with a sledgehammer. Despite that, he cried and refused social interactions for days after JFK was assassinated. Fame, money, and influence can corrupt even the best person, but that devastated him.

I've heard stories of Sinatra refusing to perform at clubs that didn't allow black people, too.
100% true. He also picked fights over it.
I think this is the best way to remember him. Not a classic tragic hero, but a man who wasn't fully in control of his mind or body. Balance any scorn with sympathy, and come to whatever conclusion you will.

While this is still super impressive it definitely looks like the middle and top ones were pre-broken and barely hanging on.
The look like karate practice boards. they slide together with a rounded dovetail joint and the instructor can adjust the force needed to break it based on how far together they're interlocked. I have no idea what the actual force needed is, I just remember them from karate dojo birthday parties in elementary school when they only overlapped an inch or two.

2 details that I noticed.

1) The knuckles say M U C K. Meaning, I can only assume, that they are not afraid to get their hands dirty.
and
2) The hornet doesn't give a gently caress that it is being shot at. Coz it is that cool/tough.

It is a pity though that none of the Tiger. Shark, or Hornet are wearing sunglasses though.
If I may add to the list:

3) Current New Jersey license plate

4) Either they have identically low tires for some reason or they're intentionally running the tires low for a bigger contact patch to try to keep as much rubber on the road as possible to handle whatever is under the hood. That's a converted church van if I've ever seen one, so either the owner missed one of the things that makes a sleeper a sleeper, or Jesus built their hot rod.

In the northern hemisphere, you can sight along the two stars of the big dipper opposite the handle and find Polaris, so you can figure out which way is north if you're lost in the wilderness or at sea.
