SS Lydia

The SS Lydia was an early warp-capable human starship operated by Earth. The ship was part of a three ship expedition to Alpha Centauri that also included the SS Tempest and SS Acheron and lasted from 2066-2068.

The Lydia continued on the return journey to Earth after the Acheron's warp drive failed, stranding it in interstellar space. While the Tempest stayed with the Acheron, the Lydia returned to Earth, taking on fresh supplies and a repair team, which it then ferried back to the Acheron. Once repairs were completed, all three vessels returned to Earth, completing the Alpha Centauri Expedition in 2068.

Afterwards, the ship was used as a testbed for new warp technology before being retired in 2078. It was disassembled and placed in Smithsonian storage in 2101.
