Coolest places you will find LINUX directing operations
This list of interesting Linux uses is by no means exhaustive. I just picked linux uses that interested me and I hope you will find it interesting too. Most of the picks came from Linuxdevices.com. You can check it out and see their cool stuff.
1. Spacecraft Embedded Control Computer
FlightLinux is a customized copy of a standard Linux distribution, adapted to the unique environment of a spacecraft embedded control computer. The first instance of FlightLinux will be on the 80386EX processor of the currently in-orbit UoSat-12 spacecraft, of Surrey Space Technology, Ltd (UK). As a basis, we are currently using the ELKS distribution, due to its small size. We will migrate to BlueCat Linux from LynuxWorks, and add real-time features as required. Custom device drivers will address the unique aspects of the spacecraft architecture.
2. Linux-based lunar rovers
[Updated Sept. 16] -- Two Linux-based lunar rovers are on maneuvers -- and Internet webcams -- this week in the Arizona desert near Meteor Crater. The maneuvers are related to a NASA project tasked with developing extra-vehicular activity (EVA) hardware and procedures for planetary surface exploration.
