The invention provides a damping unfolding locking joint with on-orbit adjustable unfolding speed and a spacecraft, and relates to the field of spacecraft structures and mechanisms. The damping unfolding locking joint comprises a first double-wing driving constant-torque unfolding hinge, a rotary damping mechanism and a second double-wing driving constant-torque unfolding hinge, the first double-wing driving constant-torque unfolding hinge, the rotating damping mechanism and the second double-wing driving constant-torque unfolding hinge are connected to the unfolding structure, and spherical rotating pairs of the first double-wing driving constant-torque unfolding hinge and the second double-wing driving constant-torque unfolding hinge form an unfolding locking joint rotating shaft. A rotating shaft of the unfolding locking joint is coaxial with a rotating shaft of the rotating damping mechanism. The damping unfolding locking joint with the on-orbit adjustable unfolding speed has the beneficial effects that the system is simplified, the on-orbit adjustable unfolding speed is achieved, and the locking impact is small, and better application adaptability and expansibility are achieved.
