Tsien was a Chinese spaceship,that appeared in the novel 2010 but did not appear in the film 2010 , constructed secretly in Earth orbit under the guise of being a mere satellite. Tsien is named after Dr. Tsien Hsue-Shen, one of the founders of the United States and Chinese rocket programs.
2010: Odyssey TwoEdit
The Chinese crew planned to use Europa's water supply to refill their propellant tanks to enable further spaceflight (allowing them to exhaust their propellant supply in a terrifically fast approach). However, soon after landing, a Europan lifeform, apparently attracted by Tsien's powerful lights, broke through the ice, destroying the ship, and killing all but one crew member. The only survivor radios a message to Leonov, and is never heard from again.
2061: Odyssey ThreeEdit
By 2061, the native Europans have stripped Tsien of all metal, which is a material extremely rare in pure form on Europa. The Europans have started a small settlement next to the wreckage of the ship, aptly nicknamed Tsienville.
