Serebrov flew on Soyuz T-7, Soyuz T-8, Soyuz TM-8 and Soyuz TM-17. He was one of very few cosmonauts to fly for both the Soviet Union and the Russian Federation that followed it. He held the record for most spacewalks, 10, until Anatoly Solovyev surpassed it. In all, he spent 371.95 days in space. Serebrov contributed to the design of Salyut 6, Salyut 7, and the Mir space stations. He helped design, and, according to a New York Times obituary, "was the first to test a one-person vehicle - popularly called a space motorcycle - to rescue space crews in distress and repair satellites." This vehicle, known as Icarus, was tested in February 1990, and remained onboard Mir for several years but was never used after that.Serebrov died suddenly in Moscow on 12 November 2013, aged 69, and was buried on November 15 at Ostankinsky cemetery.

He is also known for playing Tetris on a Game Boy in the spacecraft, making it the first time a video game has ever been played in space.
