Russia is set to launch a node module called Prichal to the International Space Station. It is expected to be attached to the space-facing port of the Nauka module.

Prichal is expected to launch atop a Soyuz rocket using a modified Progress spacecraft service module. It’s official mission designation is Progress M-UM. Following a successful arrival, the service module will be jettisoned to fly away from the outpost and eventually burn up in Earth’s atmosphere.
