Scott Manly did a video explaining it: https://www.youtube.com/watch?v=Wg2Juylb9nY https://www.youtube.com/watch?v=Wg2Juylb9nY I guess it was launched too close to Earth to maintain orbit (intentional due to the launcher's limits and other missions) and will eventually burn up as it's periapsis dips too low. The angle of eccentricity of the orbit means that the craft can only lower it's periapsis using light pressure from the sun.
