The unpiloted Russian Progress 77 cargo spacecraft undocked from the International Space Station while attached to the Pirs docking compartment at 6:55 a.m. EDT.

The spacecraft will reenter Earth's atmosphere and harmlessly burn up over the south Pacific. The mission launched and docked to the space station in February delivering more than a ton of cargo to the Expedition 65 crew.

Deorbit and re-entry will not be covered on NASA TV.

With the port on the Earth-facing side of the Russian segment station vacated by the departure of Pirs and Progress, Russia's Multipurpose Laboratory Module (MLM) is scheduled to dock at the station Thursday, July 29.

Named Nauka, after the Russian word for "science," MLM launched on July 21 and will serve as a new science facility, docking port, and spacewalk airlock for future operations.
