the United Space Alliance, which handles the computers boarded on the International Space Station in association with +NASA , has announced that the Windows XP computers aboard the ISS have been switched to +Linux . “We migrated key functions from Windows to Linux because we needed an operating system that was stable and reliable.”
This changing, it's not a surprise. +Linux is the scientific community’s operating system of choice. The +CERN Large Hadron Collider is controlled by Linux. +NASA and +SpaceX ground stations use Linux. Actually, for critical applications that require absolute stability, which most scientific experiments are, Linux is the obvious choice. The fact that the entire OS is open source and can be easily customized for each experiment is obviously a very big draw, too.
