Two cosmonauts and an American astronaut arrived at the International Space Station safely, but damage caused by their launch may delay future Russian crew and cargo flights to the orbiting complex.

Russia’s successful launch of three new crew members to the International Space Station on Thursday (Nov. 27), resulted in damage to country’s only active launch pad for crewed spaceflights to the orbiting lab, Russia’s federal space corporation has confirmed.

The maintenance cabin (also referred to as a service platform) located in the flame trench at the Baikonur Cosmodrome’s Site 31/6 in Kazakhstan reportedly collapsed in the wake of the Soyuz MS-28 crew launching to the space station atop a Soyuz 2.1a rocket. The platform is needed in the preparation of boosters launching from the pad.
