SpaceX’s 31st commercial resupply mission lifted off Nov. 4, launching a Dragon cargo vehicle to rendezvous with the Internation space station (ISS), docking to the station’s forward-facing port the next day. Today (Nov. 8), for the first time, Dragon performed an orbit-raising maneuver to stabilize the ISS’s trajectory in low-Earth orbit.
Such maneuvers are routine for the orbital lab, which requires periodic boosts to maintain its altitude above Earth and prevent its orbital decay into the planet’s atmosphere. Historically, this has been accomplished using Russia’s Soyuz and Progress vehicles, and other spacecraft, but, for the first time, it has now been performed SpaceX’s Dragon. The milestone marks a symbolic beginning of the end for the ISS, as data from the maneuver will be used toward the design of the deorbit vehicle NASA has contracted SpaceX to construct to plunge the decommissioned space station into the Pacific Ocean sometime after 2030.
