There is an abnormality with the thrusters. It may be nothing, but they can do all the work they want in the current orbit so they are not risking changing the orbit. I love that they dump the raw images on the internet and the astrophotography community is playing with the data almost in real time.

Yup. It turns out no one thought about vacuum degradation of the material used in the moving parts making up the thruster valves. And it was a five year trip to Jupiter in the hardest of hard vacuums.

Is that really what happened? I work at JPL and am tempted to walk across lab and give someone a very stern look if so. I haven't been able to keep up with Juno as much as I've wanted to just out of being too busy on MSL. :P

That is indeed what happened. Lockheed made the spacecraft, but stern looks are pretty cool, don't let me keep you from giving some out.

I take it you don't work on the pre-launch side of things, then. The QA and red tape have grown into a bureaucratic nightmare, and although Juno is only one example, I'd wager that the return on the investment into all the additional oversight is right around nothing. I'm so glad to be done with that phase of my project (MMS).

Is this geeking out? Do we tag kleinbl00 yet?

Ahh ok. It's hard to remember which spacecraft are made in house.

Oh man don't even get me started on JPL bureaucracy! I've worked on the pre-launch side of a few missions (SMAP, ARRM, Starshade), and yeah it's crazy the things we don't have oversight for, and the things we do. Part of the issue is not contracting out the positions that make so much red tape for projects trying to get their work done. Sometimes it's like they think we're toddlers...

MMS is cool though! That's out of Goddard, right? In my early research days I did some heliophysics/solar wind stuff, but anything not related to that is about as far as my magnetosphere knowledge goes. What's your take on the findings so far with Jupiter? I've heard the magnetosphere is much different than Saturn's, which is interesting to me since I figured the gas giants would be pretty similar.

I guess that was pretty geeky, so hey kleinbl00

Currently, I don't have time to put together any insight more thorough than what you could find by googling. I'll be looking at all that stuff in about a year or so from now, but until then, my singular focus is publishing my own papers.

SoooOO0oOoO0o... did you ever sell your soul to a graduate school?

rocketyak  ·  336 days ago  ·  link  ·  

Ahh ok. Was just curious.

Yep - University of Cincinnati for a MS in aerospace engineering (controls focus). And yourself?

kleinbl00  ·  338 days ago  ·  link  ·  

fuck yes

Just do me a solid and be sure to tag me whenever y'all geek out.
