NASA and SpaceX have showcased the Dragon spacecraft's capacity to reboost the ISS, successfully adjusting its orbit with a precise burn of Draco thrusters. This milestone illustrates the spacecraft's capability, similar to those of Roscosmos' Progress and Northrop Grumman's Cygnus, ensuring multiple options for maintaining the ISS's altitude.
The ISS requires regular reboost operations to avoid a potential tumble towards Earth. With the retirement of earlier systems like the ESA's Automated Transfer Vehicle, the successful demonstration of Dragon shows its viability as a future reboost vehicle.
The recent operation not only boosts the ISS but also serves as a preparatory step towards its eventual deorbiting. The data from this maneuver will inform the design of systems aimed at a controlled descent when the station's life concludes.
As the ISS approaches its expected retirement in 2030, the effectiveness demonstrated by the Dragon reboost provides NASA with options, although Russia’s commitment beyond 2028 remains uncertain, suggesting potential challenges ahead.
