The USS Trosper was an Oberth-class Federation science vessel in service to Starfleet in the 24th century. It was named in honor of Jennifer Trosper, mission manager for the Spirit rover of the early-21st century Mars Exploration Rover mission.
The Trosper was one of the first three ships to arrive at Veridian III following the crash of the USS Enterprise-D in 2371. It was their crew that discovered the visual signal being broadcast by a microtransmitter from Geordi La Forge's VISOR, which had been used by Lursa and B'Etor to penetrate the Enterprise's shields.
