Lab ship
From Tardis Wiki, the free Doctor Who reference
A lab ship was a type of spaceship. Its crew consisted of scientists.
After a planet was devastated by Praxeus the survivors were assigned to lab ships and instructed to find an antidote for the few of them left alive. Suki Cheng was of these survivors. By the early 2020s, Suki's spaceship travelled across three galaxies to find Earth, which was the perfect living laboratory. A shuttle was launched towards Earth, but it crash-landed. With the deaths of Suki and her crew, it is unknown what became of their lab ship. (TV: Praxeus)
