KOROLYOV /Moscow Region/, November 26. /TASS/. NASA and Roscosmos have begun talks on harmonizing technical standards of Crew Dragon spaceships with the Russian module and Russian spacecraft with the US segment on the International Space Station (ISS), Roscosmos Chief Dmitry Rogozin said at the Flight Control Center on Friday.
"NASA and Roscosmos have launched talks on harmonizing technical standards that will allow not only Crew Dragon or Russian spaceships to dock with the American segment but, in general, this docking is possible and will require an adapter," Rogozin said, replying to a question about whether US spacecraft would be able to dock to Russia’s new Prichal nodal module.
The Prichal module’s docking completed the formation of the ISS Russian segment, the Roscosmos chief said.
The Prichal nodal module will also serve as a prototype for similar modules for the future Russian Orbital Service Station (ROSS) that will be the ‘joints’ of its space body, Rogozin said.
"This is one of the most important prototypes for creating the ROSS whose architecture will differ from the ISS. It should employ the principle of eternal service life: modules that use up their potential will be detached from the station and it will be augmented in a different direction with the help of such nodal modules that will serve as some joints of a new and large metal design engineering body," Rogozin said.
A Soyuz-2.1b carrier rocket with the Progress M-UM space freighter and the Prichal nodal module blasted off from Launch Pad No. 31 (‘Vostok’) of the Baikonur spaceport to the orbital outpost at 16:06 Moscow time on November 24. The flight to the orbital outpost took two days. The Prichal module docked with the Russian Nauka research lab on November 26.
The new module will boost the capabilities of Russian spaceships, including the latest Oryol spacecraft, to dock with the ISS. Overall, the new module will have five docking ports. The first docking of a manned spacecraft with the Prichal module is scheduled for March 18.
The spacecraft-module also delivered about 700 kg of various cargo to the ISS, including equipment and consumables, water purification, medical control including sanitary and hygienic supplies, maintenance and repair tools, as well as standard food rations for the 66th Main Expedition crew.
