- HarHarVeryFunny 2y agoWhat about the port currently used by the Northrup Grumman supply ship - is that not compatible with Dragon ? Is there no adaptor to make the Russian Soyuz/Progress ports usable by Dragon ?
- richardwhiuk 2y agoI believe there's a difference between the cargo ports and ports suitable for manned vehicles. [Edit] The difference, is that Cygnus berth by Candarm to a berthing port, while Crew Dragon, Starliner and Cargo Dragon dock to a docking port.
- HarHarVeryFunny 2y agoThanks! Googling more about this, it seems the Russian portion of the ISS has 4 docking ports, but US portion has 2 docking + 2 berthing ports, and the Russian ports are not compatible with the US ones. There is also apparently a US "pressurized mating adaptor" (PMA) that adapts a "common berthing mechanism" (CBM) port to a docking one, which sounds as if it might (if one were available, and could be installed) be able to adapt one of the US berthing ports for use by Dragon.
