Mysterious is not a good word because these types of launches are launched by all major sspace angencies routinely like CNSA , ROSCOSMOS and NASA . Therefore , I would suggest you to please rename it to "Classified" as obviously no one would be able to know the details of some of those launches.
Normally, there is a manufacturer stated that eventually allows for figuring out the mission and technology being tested. Without that, it is mysterious what the spacecraft is doing.
