Remember when you went to see Avengers Endgame and the audience reactions were as much fun as the movie?

20% of my ‘following’ feed is ads. When I login with a non blue account: 20% ads. So the ‘half the ads’ part isn’t working either.
I mean twitter blue isn’t intentionally a scam, but the current company clearly doesn’t have the ability to deliver what they’re promising.

So I contacted twitter support about tweet editing not working:
* 1st response: Are you sure you did it right, and know the time limits?
* Yes I’m doing it right.
* 2nd response: ”Oh, this is a known bug.”

I think Anna Kikina may have heard about the biggest hair record and decided to give it a go.

So, does Marsha Ivins hold some kind of record for the biggest hair in space?

Hey !
It can be hard to meet new people in the terrifying vacuum of space.
How’s it been going?

Bad news - was supposed to show a flight instructor I can fly solo, weather is not accommodating.
Good News - I now have all the parts to my new PC.

Honestly this balloon is living a dream. Grew up in China, took a really risky trip across the Pacific, shows up in the United States and boom: overnight celebrity. It's experiencing its own American dream and I say it's wonderful. We should get him/her a few brand partnerships.

Every time I see a game include a 'High Contrast Mode' in the graphics settings my mind immediately wants to turn it on and hear some tunes in the soundtrack.

Price is twice what we paid in 2004. It still has 'flow issues' which make it hard to get to the back yard. Still has the same bathtub. The master bedroom no longer has the amazing view. And I notice there's now a deck over the manhole cover in the back yard.

I just wasted the last hour looking at how they remodeled my old house. Glad they kept my brick patio, I spend a long time laying that. At the same time they could have replaced the ancient windows.

Sad News.
I googled it and it's been removed, The house is now two separate units.
But they now have a tiki bar in the back yard.

In the 1950’s the CIA were flying spy balloons over the USSR. Those balloons were made by General Mills, maker of breakfast cereals.
And the story got crazier.

The CPU heat sink is bigger than I expected, bigger than the power supply.
I hope it’ll fit in the case…..

There's a surprising amount of video from STS-107 showing the crew loving what they're doing, here's a clip showing how they dealt with trash.

I put this together this video showing Columbia's breakup in real time, starting with the recovered cockpit footage, following through the telemetry failures and finally the breakup simulation based on all the evidence.
Sensitive content obviously.

NEW from NOAA SOS: This dataset shows the tsunami wave caused by the asteroid that hit Earth 66 million years ago. The wave was so impressive because the asteroid is estimated to have been 6+ miles (10+ km) in diameter! Want to learn more? sos.noaa.gov/catalog/datase

That's one way to avoid stalling the development program with heat shield problems still to solve.

There were many other difficulties which made this impractical, getting to the work site without the RMS, and also the importance of shaping the surface to keep the airflow smooth and reduce the aerothermodynamic hotspots.
I’m mostly interested in ice composites vs entry heating.

So has anyone seen any research testing an ice composite in a plasma wind tunnel or similar? Any considerations as to what would be an ideal reinforcing material? Paper is easy to find, towels and other fabrics also. But there were things like Nomex insulation on hand too.

Pycrete is one famous example using wood fiber to increase strength but also decrease thermal conductivity. This material was featured in Mythbusters youtu.be/UMKis4FPykw and they showed you could use if for ships, I’m sure it would be better than plain ice for spaceships.

Does anyone know if there’s a more detailed analysis, or investigation on what scavenged materials might make the best heat shield. Every mention just talks about bags of water, but I can’t imagine NASA engineers wouldn’t consider mixing some fiber reinforcement.

You might think that blocks of ice can’t even remotely compete with the carbon-carbon, but it’s important to remember that the heat shield is designed to be light, but a local ‘repair’ would involve stuffing a lot of mass in one location, increasing the time it takes to fail.

There’s been lots written about a hypothetical rescue concept for Columbia requiring launching the next shuttle in line. However there was some consideration given to an on-orbit repair, filling the space behind the RCC panel with material and bags of water, which would freeze.

I currently have an i7 6700K, and I guess top of the line CPUs once deliver single core performance that’s about twice as fast. And, with more cores available.

Another thing driving this is I gave Orion a new GPU for Christmas and his 10 year old PC doesn’t like it. So if I give him my old system he’ll be better setup for everything.

I kept looking to upgrade in the past but single thread performance hadn’t shown much movement from the build I did. Will probably keep my 3070 GPU initially and most of my disks. New Mobile, CPU, Case etc.
Hard part is moving things over, this isn’t iOS.

Remember that image of an astronaut using a flight sim on the space shuttle in orbit? I've found a slightly cooler one.
That's STS-90 Pilot Scott Altman, the pilot who flew the F-14 for Top Gun, getting in some landing practice.
And yes, during launch they were flying inverted.

An astronaut once said wasn't realistic because astronauts don't fly spacecraft with computer keyboards. But I found the keyboard controls for AERCam which was a camera drone tested for flying around in space during EVAs.
