4.3 ISS Windows contaminated by virusIndexup to index

Most International Space Station [ISS] computers already run GNU/Linux:

GNU/Linux chosen as operating system of the International Space Station: Gnus now join astronauts of many countries in humanity’s biggest space station. This is a wise choice for the space station, and a high-profile victory for software freedom. It brings good publicity for free software, demonstrating its respected position in the world of science and technology.

They finally had to fix the laptops on the ISS:

Although Windows 8 offers built-in anti-virus software called Windows Defender, the ISS really needs an operating system that is less targeted for cyber-attacks than Windows, according to ExtremeTech. The ISS has already experienced the headache of having infected computers onboard after a Russian cosmonaut accidentally brought a laptop infected with the W32.Gammima.AG worm to the station, which ended up contaminating all the other laptops on the station.

The solution was to dump Windows in favour of Linux:

The United Space Alliance, which manages all of the space station’s computers in association with NASA, made the decision to migrate key functions from Windows to Linux, “because we needed an operating system that [is] stable and reliable,” Keith Chuvala of United Space Alliance said in a Linux Foundation press release.

Most systems on the space station already use some form of Linux, including the Robonaut 2, which is expected to take over some of the “tasks too dangerous or mundane for astronauts in microgravity.” The R2 is already a Linux-bot, so both the on-board astronauts and the ground crew are trying to learn to use the platform to better communicate with the first humanoid robot in space.
