BAIKONUR, Kazakhstan: The space-age version of knights in shining armor blasted off to the rescue of Mir today. Commander Anatoly Solovyov and flight engineer Pavel Vinogradov are racing to the troubled space station to perform vital repairs — and they were never more needed. True to form, Mir's oxygen generators broke down this morning. TIME's Dick Thompson says this latest mishap is no cause for alarm: "To the Russians, this is just life as normal," he says. The two cosmonauts are expected to dock Thursday.
