A laboratory still in operation
The ISS encounters a small amount of atmospheric drag even at its orbital altitude and periodically needs manoeuvres to raise its orbit. NASA has stated its commitment to operate the station through 2030; the plan and operational dates may evolve. Reboost manoeuvres did not cease in 2026.
Why a controlled re-entry?
The station is large and some parts could survive passage through the atmosphere. NASA and its partners evaluated several options and plan a controlled re-entry towards a remote ocean area to reduce risk to populated regions.
A complex transition
The plan includes a dedicated deorbit vehicle and coordination among international partners. At the same time NASA intends to support a transition to commercial destinations in low Earth orbit. Milestones depend on system development and partners’ decisions; they are not fixed forever.
