Space Exploration II: Always Looking up

In happier space news, Blue Ghost 1 is still working on the moon. Starting to do some drilling tests. Working hard enough that it's scheduling power cycling to keep it cool enough. Good for them!

SpaceX Has Finally Figured Out Why Starship Exploded, And The Reason Is Utterly Embarrassing

This should never have happened.

And Elon's vanity project is turning out to be a more expensive and less useful Saturn rocket. NASA of 50 years ago was more capable than the Starship project.

What a fantastic article. And a trendline I have been seeing for over 30 years during my career in supporting Engineers and their work.

Wait, they aren't x-raying their welds or pressure testing their fuel systems?

That will compromise build speed.

But the other issue is that they know what the vibration is, but don't seem to be capable of replicating it on the ground to test, understand the failure, and fix it.

Pretty sad.

That's not the engineer making the decision to skip processes, it's the management. Who are the same management who told the engineers to find a process to prevent the failure in the first place.

It's boring to blame the engineers and pretend they are the cause- it's always the people telling them to skip things.

They need to improve the back half of that quote.

The pace of producing the product is way faster than pace of development, and managers hate that. I can't tell you how many times flaws went to production at F because steps were skipped due to development issues. And then they stayed in because the cost of warrantee were put into other groups instead of development.

I also recall when managers openly mocked the movie Titanic because they had so many delays. Titanic cost a lot of money to make, but more than made up for it being such a well made movie. But no manager or VP looked back on that and noted that 2-3 months late and a better product would be better than paying billions in warrantee costs.

S-X is doing that to make elmo look "good", and it's the opposite. But he doesn't care, as we are all paying for S-X's failures.

Trump's newest issue with Butch and Suni is, per government rules, they get their base salary plus $5 / day for being away on a business trip. All meals and lodging are (obviously) taken care of on the ISS.

Astronauts get paid based on a 40/hr work week, even when stationed on the ISS. They don't not get OT or holiday pay on the ISS.

Its been this way since the start of the space program. And now Trump thinks they're owed something extra because of the delay bringing them home. He's even said he'll pay it out of pocket.

Wilmore and Williams' ride to the Space Station was wilder than anyone let on.

arstechnica.com

Starliner’s flight to the space station was far wilder than most of us thought

“Hey, this is a very precarious situation we’re in.”…
arstechnica.com arstechnica.com

We're already past the point where we were supposed to leave, and now we're zero-fault tolerant and I'm manual control. And, oh my, the control is sluggish. Compared to the first day, it is not the same spacecraft. Am I able to maintain control? I am. But it is not the same."

"And this is the part I'm sure you haven't heard. We lost the fourth thruster. Now we've lost 6DOF control. We can't maneuver forward."

Just as the thrusters were needed to control the vehicle during the docking process, they were also necessary to position Starliner for its deorbit burn and reentry to Earth's atmosphere. So Wilmore had to contemplate whether it was riskier to approach the space station or try to fly back to Earth. Williams was worrying about the same thing.

"I don't know that we can come back to Earth at that point. I don't know if we can. And matter of fact, I'm thinking we probably can't. So there we are, loss of 6DOF control, four aft thrusters down, and I'm visualizing orbital mechanics. The space station is nose down. So we're not exactly level with the station, but below it. If you're below the station, you're moving faster. That's orbital mechanics. It's going to make you move away from the station. So I'm doing all of this in my mind. I don't know what control I have. What if I lose another thruster? What if we lose comm? What am I going to do?"

The more I read about Space-X the more you realize that Musk is just a pobzi scheme with a pyramid scheme on top of it. If Space-X doesn't fix its issues even a bailout won't save it and if it goes down pretty much all of Musks businesses are dead.
 
Sent Katy Perry into space for 5 minutes to "inspire women," while simultaneously removing all bios of women and their accomplishments from the NASA website.

My brain hurts.

They are definitely not on the GPS side. L3Harris has had to bail them out numerous times (I know, because I used to work on the GPS project at L3Harris, including the contracts which were transferred from Boeing to us because Boeing couldn't deliver squat).

Boeings loss turned into Ford's gain. They turned away from the right choice, and thankfully, Bill Ford saw that Mullaly was available- who literally saved Ford Motor Company. Boeing's demise started with the Mc-D acquisition, they kept the inept Mc-D management- who literally ran Mc-D into the ground- to help run Boeing- the end got going. When they made the hard split to no promote Alan Mullaly to CEO, it was over.

It's going to take more than 20 years to repair Boeing, if they ever can. It's too bad the union has suffered so much that they can't buy their way onto the board.
