New ISS Deal: NASA Astronauts on Russian Rockets, Cosmonauts on SpaceX Rockets
"NASA astronauts will go back to riding Russian rockets under an agreement announced Friday," reports the Associated Press, "and Russian cosmonauts will catch lifts to the International Space Station with SpaceX beginning this fall."The agreement ensures that the space station will always have at least one American and Russian on board to keep both sides of the orbiting outpost running smoothly, according to NASA and Russian officials. The swap had long been in the works and was finalized despite tensions over Moscow's war in Ukraine, a sign of continuing Russia-U.S. cooperation in space.... No money will exchange hands under the agreement, according to NASA.... Friday's news came just hours after the blustery chief of the Russian space agency, Dmitry Rogozin, was replaced by President Vladimir Putin, although the move did not appear to have any connection to the crew swap. Rogozin was expected to be given a new post. CBS News explains the NASA-Roscosmos agreement:"The station was designed to be interdependent and relies on contributions from each space agency to function," the NASA statement said. "No one agency has the capability to function independent of the others..." Russia provides the propellant and thrusters, either on the station or visiting Progress cargo ships, to change the station's orbit and offset the effects of atmospheric drag. NASA provides the bulk of the lab's electrical power, the massive gyroscopes that help maintain the station's orientation and a station-wide computer and communications network. Russian cosmonauts are not trained to operate U.S. systems and vice versa, meaning at least one astronaut and one cosmonaut must be aboard at all times. If either side pulled out, the other likely would have to depart as well, or quickly come up with alternative systems. "NASA wants to operate the space station through 2030," adds CBS, "but Russian cooperation is required. And it's not yet known whether Russia will go along."
