A United Space Alliance team supporting International Space Station crew laptops moved key functions from Windows to Linux to gain stability, reliability and control over patches and adaptations, according to a Linux Foundation case study published March 27, 2013. The Foundation says it arranged tailored developer training for the team. The account concerns specific laptop and network functions—not a claim that every computer aboard the ISS switched operating systems.
What the ISS team was changing
Keith Chuvala, identified in the case study as a United Space Alliance leader for the Laptops and Network Integration Teams, oversaw developers writing and integrating software for OpsLAN, a network of laptops supporting crew tasks. The case study names location information, equipment inventory and camera interfaces as examples of its functions.

Chuvala described the reason for the change: “We migrated key functions from Windows to Linux because we needed an operating system that was stable and reliable – one that would give us in-house control. So if we needed to patch, adjust or adapt, we could.” The decision, as presented in the account, was about operational requirements and the team’s ability to manage its software—not a published benchmark showing Linux outperforming Windows in general.

The Linux Foundation says its training staff arranged two courses for the USA/NASA team: “Introduction to Linux for Developers” and “Developing Applications For Linux.” The sessions were tailored to a group with varying levels of experience and a mixed distribution environment.
#1 Best Overall
That environment included a substantial Debian deployment as well as multiple versions of RHEL/CentOS. The case study reports that the team moved from Scientific Linux to Debian 6 in the laptop-support context. Instructor Dominic Duval characterized the environment as highly heterogeneous and said the training could address different distributions in a single session. These are historical details from the 2013 account, not a description of current ISS software or currently available courses.
How Linux fit into the ISS computing context
A NASA technical reference, The International Space Station: Operating an Outpost in the New Frontier, separately describes the station’s Portable Computer System as using Scientific Linux and as an interface through which crew members could interact with station systems. This gives technical context for Linux-based portable computing on the ISS, but it does not independently verify the Windows-to-Linux migration timeline described in the Foundation’s account.

The Linux Foundation case study also mentions Robonaut 2 (R2) as a development challenge and says the robot ran Linux. That is what the 2013 story reported; it should not be read as a statement about R2’s present status or software configuration.
What the account does—and does not—establish
The case study describes “dozens of laptops” and quotes Chuvala saying the ISS user constellation “maxes out at six,” in reference to users with specific requirements and duties. Those figures are attributed to the 2013 account, not independently verified current counts or station-wide totals. Neither source provides a quantified before-and-after performance result, and neither establishes the ISS’s current laptop operating systems.
