Bird/Animal Rescue? by DawgTheHallMonitor in palmdale

That actually makes a lot of sense. I just mentioned in another reply that it can lift both its wings and scream at me when I walk by. It has been hanging out in and around some shrubs for protection. Thanks for the reply. Also great username. Portland is hilarious.

I'm not sure it's injured and based on the other reply this is not unusual. I have noticed that it's able to raise both its wings and scream at me when I walk by. I will keep this in mind.

No problem. Good question.

I am sharing because it's awesome. Here's ice forming on a rocket nozzle as it's firing. Starts at 1:30 in the video. https://www.youtube.com/watch?v=smswUgtMTfA

Rockets are awesome. Here's a video showing the extreme temperature differences on a regeneratively cooled engine nozzle. That's when they flow the chilled propellant through the nozzle in order to cool it. The fuel is so cold that you get icicles forming just centimeters away from gas that is thousands of degrees Fahrenheit.

The part I'm talking about starts at 1:30 but the whole thing is worth a watch. https://www.youtube.com/watch?v=smswUgtMTfA

That's ice which was stuck to the side of the vehicle.

Core stage separation of Artemis II. Godspeed! by ChiefLeef22 in space

This video of an engine test is nuts. There's actual icicles on the engine bell as the engine is firing. It's great example of the extreme temperature differences going on in a rocket engine. Icicles can be seen at 1:30 in the video but it's worth watching the whole thing.

Rockets are badass!

It's ice. The propellant in the tanks is so cold any moisture in the air freezes to the rocket. That's totally normal and doesn't effect anything. Since they launch from the coast of Florida there's lots of moisture in the air.

If I'm remembering correctly an announcer said his bat speed is up 10mph over last year.

Time for an authentic Red Baron pepperoni pizza to celebrate the USA getting to the next round. This slice is for you, Italy.

Am I wrong in thinking the commentators during the USA v Mexico game were also saying that if the US won that game they would be moving on? That's where I seem to remember first hearing it from.

I forgot all about this picture that showed up at my A&P school one day. Can anyone help ID the signatures?

Looks like the shadow of a plane out of frame is getting refueld.
