The International Space Station went into an uncontrolled mode on 4 Feb when the Russian-built computer that handles navigation data lost two of its three data streams. The station went into free drift and rolled, which meant that the solar panels were no longer facing the sun and the communications antennae were no longer facing their ground stations. The crew went into manual mode, "flying" the station and manually pointing its arrays and antennae, until the computer could be restarted several hours later.--Stephen V Cole
