The two-decade-old Pirs airlock and docking chamber were removed from the International Space Station by a Russian Progress cargo ship early Monday, clearing a path for the delivery of Russia’s new Nauka multifunctional lab module on Thursday. At 6:55 a.m. EDT, the Progress MS-16/77P supply ship was instructed to return from Pirs, with hooks and latches securing the docking container to the Zvezda service module’s Earth-facing port commanded open. The Progress activated its engines at 10:01 a.m., setting up a 41-minute devastating descent into the air after relocating a reasonable distance.
