Watch SpaceX’s Starship splashdown in the Indian Ocean at end of fifth test The job of boosting the space station has traditionally been performed by Russian Soyuz spacecraft, but NASA has been looking for another solution to lessen its dependence on Russia, particularly following the invasion of Ukraine. The idea of using a Crew Dragon for reboosting not only the ISS, but also other missions such as the Hubble Space Telescope, has been raised in recent years as the vehicles have been frequently used for carrying both astronauts and cargo to the station and back. There were also occasional tests of using Northrop Grumman Cygnus cargo vehicles to reboost the station, but these cargo vehicles are designed to be expendable — they are sent to the station to carry cargo, but then are disposed of in space rather than landing back on Earth — so they are not ideally suited to reboosting. The Dragon is also not specifically designed to do this job, as its main task is to carry cargo, but the option to use it will give more data on eventual ISS deorbit plans. The Dragon arrived at the station carrying around 6,000 pounds of supplies this week and will stay docked until it returns to Earth. There have been some unusual issues with SpaceX launches using its Falcon 9 rocket recently, which are notable as the rocket is generally so reliable. But NASA said it was confident that SpaceX could continue to do the job. “We work very closely with SpaceX on everything that we do relative to these Dragon launches,” said Bill Spetch, operations integration manager for the NASA’s International Space Station Program. “They share data with us very freely, and we work through all the issues jointly. We obviously always maintain a top priority on the safety of the vehicles coming to ISS, and so that really hasn’t changed for us.” Editors’ Recommendations
