Check out his awesome new base! Centaur.

My addition to the poster being gifted to NASA/JPL Tweetup staff in appreciation from the group. I forgot to close a parenthesis. Oops.

If you ever get the chance to go to a NASA tweetup, do it. Even besides the amazing access and the people we got to meet, we were also laden with swag. Handouts, sure, but also a mission pin, mission patch, mission sticker, mission info book, mission info CD, a picture of the STS-129 crew, plus more pics and infopacks and an Ares mission pin and stickers and a chunk of insulation that's been on a flight and a "Celebrate Apollo" DVD with 4 hours of footage and features from 40 years of spaceflight. I mean, geez. Added to the bus tour we received, which went closer than the paid tour goes, we received well over $100 worth of loot.

This was a bit of a memory experiment. Before the launch, I remember @schierholz gave us some advice. She said when the time comes, put down the tech. Nasa has millions of dollars of cameras and video (and they're better than yours!). She wanted us to just feel it, whatever that meant for us.

I decided on a personal experiment: no tech at launch, and after the launch I wouldn't look at others photos or video from my vantage point. I wanted to experience, then keep the experience, until I could record it myself, without help.

This is a recording.

New trucks had started to arrive on the potential launch day.

I'm probably just a little too happy to be sitting there

It's like Canaveral's own Chocolate Hills.

I'm not sure if these are a permanent installation, or if they're just put out when folks from NASA at Cape Canaveral are visiting, but they sure seemed out of place on the primordial California base.

We found it amusing the night before the #nasatweetup we went shopping for snacks and found this amazin 0.01 savings.... Really...

The NTF is a high-pressure, cryogenic, closed-circuit wind tunnel that uses supercold nitrogen gas at high pressure to duplicate true flight aerodynamics.
