A fire in a TsNIIMash building basement, the facility that houses Russian ISS mission control, was extinguished with no injuries reported.
what happened
A fire broke out around 1 p.m. local time on August 5, 2026 in the basement of a building at TsNIIMash, Roscosmos's main research center in Korolyov outside Moscow, per The Moscow Times and Ukrinform. Staff were evacuated and firefighters extinguished the blaze; no injuries were reported. TsNIIMash houses mission control for the Russian segment of the International Space Station. Roscosmos said an internal commission will determine the cause once the site is fully cleared; TASS cited anonymous sources pointing to a possible short circuit.
why it matters
TsNIIMash's mission control role makes any incident there relevant to ISS operations, which NASA and Roscosmos jointly run under the seat-swap arrangement the two agencies extended this same week. Roscosmos said ISS operations "remain fully under the control of specialists," with no disruption reported.
