Thanks for the insight!
I guess it IS very different to believe, for decades, in a mission that includes space telescopes than in the latest SaaS or productivity app or something more "mundane". Not that there's anything bad working on those kind of projects, but it sure has a different scope (no pun intended)
On a less sarcastic vein, some people find a job that they really like and enjoy. The pay may not be as much as somewhere else, but a satisfying job that is stable and provides for ones needs seems to be a concept lost in the tech (silicon valley) world. It's all about rocketships to the moon type of salary wants. If I found a gig like that sending manmade thing to another planet/moon that ultimately advanced human understanding, I'd definitely be willing to retire in that role. In today's world, there are plenty of other side hustles to help offset income needs. I'm a survey of 1 though.
As someone who hires people, lots of 18 month stints would certainly turn me off the candidate.
The project I worked one was migrating data from their in house ticket tracking system to Jira. I was importing tickets from 1985 into Jira which obviously didn't exist at that time.
