Re: [PSAS] Shuttle Launch Party
I'm in2 it. Gotta be at a meeting at 10 at PSU in any event... On Wed, Jul 6, 2011 at 11:29 PM, Nathan Bergey nat...@psas.pdx.edu wrote: I was hoping that a few people might want to get together to watch the very last shuttle launch ever live on screen somewhere. This is a pretty historic event for rocketry and for humans in general. Unfortunately it's going to be early in the morning here. The target launch time is 8:21:46 am Friday morning. There is a lot going on in the last few hours before launch, so if anyone does want to meet up, at least an hour before launch would be a good idea. Reply if you want to meet up, and if anyone can get us into the conference room where we normally meet that would be awesome because I know it has a projector and internet. Otherwise I highly recommend everyone setting apart some time on Friday morning and tune into http://www.spacevidcast.com/ and watch the launch live. They're already streaming coverage 24/7 now. As I write this the countdown clock is at T-13:34:15 and counting. Also watch your email because I will update with any information about scrubs or off-nominal conditions. -Nathan ___ psas-team mailing list psas-team@lists.psas.pdx.edu http://lists.psas.pdx.edu/mailman/listinfo/psas-team This list's membership is automatically generated from the memberships of the psas-airframe, psas-avionics, and psas-general mail lists.

Re: [PSAS] meeting tonight, including geometry/physics discussion
I have a copy of the same book Dan recommended for quaternions in the mail, so while I'm looking forward to your condensation of the important bits, I'm going to hold my own questions off for a few weeks while my book arrives and I wrap my head around the math.

We're going to look into reserving FAB 86-01 for future meetings, and we'll announce tonight if that worked out. Last week Ben and I chatted about taking an hour of the regular meetings to explore rocket physics and, at his request, geometry topics---first up, quaternions. So let's try that tonight. During tonight's regular weekly meeting, from 8pm to 9pm anyone who's interested is invited to chat about rocket physics: how physicists model the forces on a rocket in the abstract, and how a practical computer model of those forces should work. I took some time last week to wrap my head around quaternions so I'm prepared to discuss what they are, why you want to use them in practical physics models, and how the important operations on them work. If we have time, I'd like to follow that up with discussion of how to implement forces that cause rotation in rockets. Several people in PSAS have been trying to explain this stuff to me over a period of years and I'm hoping to get some of it to stick, preferably in the form of executable code. See you tonight!

Re: [PSAS] Fwd: staging designs, code inspection
I have some questions about masses as defined as well. If the proposed numbers mean anything, I'm not sure our final mass can be 1.22 kg. We need weight of last stage tanks, motor(s), etc. with the 1kg cube-sat. This is what I was talking to Dave about this past Saturday - I'll explain the estimation procedure to anyone interested tonight.
