Nice. I'm working on an experiment that'll fly on the ISS next year, using 4 ARM processors. It will also be running debian: Linux stick1 2.6.39 #1 Mon Aug

Nice. I'm working on an experiment that'll fly on the ISS next year, using 4 ARM processors. It will also be running debian:
Linux stick1 2.6.39 #1 Mon Aug 15 19:04:09 PDT 2011 armv7l GNU/Linux
And:
root@stick1:/usr/share# cat /etc/issue.net
Debian GNU/Linux 7.0
Should be interesting. :-)
- DavidSJ 13y agoWhat experiment? And is it flying on Dragon out of curiosity?
- jzawodn 13y agoIt's going to be testing 4 Gumstix modules on the external NanoRack platform. Here's the grant announcement: http://www.iss-casis.org/NewsEvents/PressReleases/tabid/111/ArticleID/61/ArtMID/586/CASIS-Announces-Grant-Awards-for-Materials-Science.aspx http://www.iss-casis.org/NewsEvents/PressReleases/tabid/111/... And, yes, I believe it'll be flying on Dragon.
- DavidSJ 13y agoCool! We'll do our best to get it there safely. :)
- voidlogic 13y agoDo you have to use radiation hardened components, shielding, and a multi-core compute and vote kind of system?
- jzawodn 13y agoThe watchdog circuit is built using radiation hard components, but aside from maybe light shielding on the micro SDCards we'll be flying the modules as-is. The goal is to characterize them in that environment and determine failure rates to see if it's reasonable to then build a fault-tolerant system (using voting, as you suggest) later on.
- voidlogic 13y agoVery cool, thanks. I'm envious of your assignment.
