The Russian Prichal docking module arrives at the International Space Station.

The five-ton Prichal docking module arrived at the International Space Station at 10:19 a.m. EST, propelled by a modified Russian Progress propulsion compartment.

They docked to the Nauka module on the Earth-facing side of the Russian segment two days after lifting off from the Baikonur Cosmodrome in Kazakhstan Wednesday, Nov. 24 at 8:06 a.m. EST (6:06 p.m. Baikonur time). The spacecraft were flying about 260 miles over Ukraine at the time of docking.

To make room for Prichal, the uncrewed Progress 78 cargo craft undocked from Nauka at 6:23 a.m. Thursday, Nov. 25, and burned up upon reentry in the Earth's atmosphere later that morning.

Prichal, named for the Russian word for pier, has five available docking ports to accommodate multiple Russian spacecraft and provide fuel transfer capability to the Nauka module. Named for the Russian word for "science," Nauka launched to the space station in July.

The modified Progress transport spacecraft that guided Prichal to the station will remain in place until late December.
