For more than two decades, the International Space Station has relied on regular boosts to keep it from slowly drifting toward Earth. These reboosts counter the drag caused by the thin atmosphere still present 400 kilometers up. And for most of that time, one country handled the job almost entirely on its own — Russia. Whether through Progress cargo ships or the station’s own thrusters, this was their domain. The United States, despite being a leading partner in the ISS program, never had a dedicated, independent system to take over that role.
But that balance of power in orbit may be about to change. In recent months, a quiet shift has been taking place — one that changes how the ISS is maintained and could influence international partnerships in space. NASA has recently tested a new capability using SpaceX’s Dragon spacecraft, marking the first time a U.S.-built vehicle has executed this operation independently. This upgrade is designed to deliver higher thrust than Russia’s Progress vehicles, and its adoption could shift long-standing operational roles aboard the station while reducing reliance on Russian hardware.
