Как один баг чуть не убил марсоход за $400 млн, и почему везде важна конфигурация

3 января 2004 года марсоход «Спирит» коснулся поверхности Марса в кратере Гусева. Двадцать один день спустя он перестал отвечать на команды, ушёл в бутлуп и чуть не погиб от своей же операционки. О том, почему инженерам JPL этот инцидент до сих пор снится в кошмарах, как NASA дважды чуть не потеряло марсоходы из-за одной и той же ОС и почему везде важна правильная конфигурация — в статье.

Great news, the NASA SPHEREx satellite has started talking to the ground stations, so it is orbiting and working well.

NASA Radar Imagery Reveals Details About Los Angeles-Area Landslides. Landslides on Palos Verdes peninsula have been moving rapidly in last two years. NASA airborne radar called UAVSAR flies on piloted NASA planes and measures displacements of the ground surface using InSAR analysis. We requested flights in three directions to map motion of landslides on the Palos Verdes peninsula next to Los Angeles. #NASA #NASA_JPL #InSAR #radar #landslides

8% of #NASA_JPL being laid off. The mood on lab was already dire when I left two years ago. I worry that this isn't the only hammer that will drop on the space sciences this year, with the House fighting to cut federal spending levels.
