State media agency RIA says that NASA and Roscosmos are negotiating an agreement that would eventually allow SpaceX Dragon spacecraft and other future visiting vehicles to dock to a new Russian ‘node’ module recently installed on the International Space Station (ISS).

Weighing almost four tons (3890kg/8600lb), Prichal is a 3.3m (~11ft) wide spherical pressure vessel whose sole purpose is to receive visiting cargo and crew vehicles and (in theory) enable further expansion of the space station’s Russian segment.

Only fourteen years later – in July 2021 – did Roscosmos finally manage to finish and launch the module, which then proceeded to perform a long, uncommanded thruster firing that could have easily damaged or destroyed the entire station on the same day it arrived.

Now, while odds are firmly against Prichal ever supporting another Russian ISS module, the ‘node’ still has plenty of potential operating solely as a docking hub or (per its namesake) a pier.

Outfitted with six docking ports, one of which now connects it to Nauka and the rest of the ISS, the other five ports are effectively free to be used by any arriving Russian spacecraft – including Progress cargo ships, Soyuz crew vehicles, and next-generation Orel (Eagle) spacecraft.

However, according to Roscosmos and state media outlet RIA, SpaceX’s Crew and Cargo Dragons and other US spacecraft set to use the western International Docking Adapter (IDA) standard could be added to the list of possible tenants.

Even now, with just two spacecraft (Crew and Cargo Dragon) to worry about, NASA is forced to very carefully schedule arrivals and departures and has already had to have SpaceX perform multiple Crew Dragon port relocation maneuvers to prepare for the arrival of other Dragons.
