Mission details:

• The D-SAT cubesat from D-Orbit of Italy was launched in June, 2017 to demonstrate a solid motor deorbit system. The satellite was in a 496 x 508 km x 97.4 deg orbit. The motor was fired at 2018 UTC on Oct 2, 2017; however a misalignment of the motor with the satellite centre of gravity apparently caused the vehicle to tumble during the burn, and instead of achieving an estimated 180 m/s retrograde to put it in a -117 x 507 km deorbit path, the burn contributed 51 m/s posigrade and 40 m/s out of plane, raising perigee 190 km and leaving D-SAT in a 506 x 686 km x 97.6 deg orbit, increasing its expected orbital lifetime.
