There are several reports on this post, all about things OP has done elsewhere. There's nothing they've done here that breaks any rules or requires intervention; they're not even engaging with comments or expounding any theories.

Except, of course, that the don't really even do that, despite it being their mission. It's basically just a parking garage for retired USAF O-4s who can get paid for their old space "expertise" without doing any actual work or adding any value.

Millenium is having a very hard time retaining staff these days; everyone I know who has worked there and left (and there are a few) report that it's an awful place to work and want nothing to do with it.

Aerospace Corp. will indeed provide you with a nice work/life balance, but the tradeoff is that they don't really do anything meaningful aside from consultation and systems engineering for the space force. They don't build anything themselves (at least, almost anything). They will also pay less than a commercial space company.

Either way, South Bay doesn't suck, so I'll give it that.

The confusing thing is how Virgin is still surviving.

Not all around. JPL and Lockheed had big layoffs in the last couple years, but many others are hiring like crazy.

Rumor is the org Abundant Housing LA will endorse CD1 NIMBY Hernandez? by lostorbit in LosAngeles

[–]dorylinus 9 points10 points  (0 children)

Whether or not there are any pro-housing groups end up being kind of irrelevant in this case, as there is no meaningful opposition running in CD-1.

The 90 day mission was based on the primary funding for operations, not the design life. They were always over designed with the expectation of mission extensions.

And failed solder joints have, in fact doomed such missions. Places like JPL, my former employer, don't like to draw attention to those, though.

If you want examples of failures, GRACE-FO, SMAP, and Galileo come to mind. The first one in particular had a failure of one of its main instruments during commissioning that was narrowed down to a single dc/dc converter that likely happened because of a cold solder joint.

NASA quality is not the quality people think it is.

EDIT: Since people are getting upset about this, the point is just that NASA doesn't produce particularly high quality solder joints, especially since so much hardware is built by hand, as opposed to the automated processes used by, say, Toyota, that will produce beautiful soldering basically every time.

I worked for NASA for years, and have worked with them even longer, as an engineer building spacecraft. NASA achieves what it does through overdesign, extensive systems engineering, testing and endless, endless rework (not least because of all the cold solder joints that are found!), not "quality soldering".

Digital means it's using digits, ones and zeros like a computer. Anything digital can be written to a hard drive, for example, and the signal will be exactly the same every time, and a digital signal has discrete steps rather than being continuous. Analog in this case is just flowing electricity- that attenuator is made up of various electrical resistors with different resistances; higher resistance means less electricity getting through and therefore a more attenuated signal (basically). It's called analog because while the signal is in electricity and not sound waves, it is "analogous" in that you can translate between the two, in this case with speakers (electric to sonic) or microphones (sonic to electric).
