Alexey Leonov (30 May 1934 - 11 October 2019) was a Human man, a Russian astronaut in the service of the Soviet Union who lived on the planet Earth during the 20th and 21st centuries.


Leonov was known for being jovial and good spirited. (ST reference: Spaceflight Chronology)

On 18 March 1965, Leonov piloted the Soviet Vostok-2 spacecraft into Earth orbit and became the first human to walk in space. Attached by a cable, he space-walked for 10 minutes, proving that humans could survive outside a spacecraft. (Star Trek Annual 1969 article: Who Was First?)

In 1975, Leonov commanded Soyuz 19, which docked with an Apollo program vessel in Earth orbit as part of the historic Apollo-Soyuz mission. Leonov joked with with Apollo's commander Thomas Stafford not to forget the breaking thrusters. In the docking collar between both ships, Leonov shook hands with Stafford.

Following his return to the 23rd century from 1969, James T. Kirk said he would have been honored to meet Leonov, among other astronauts. (DTI novel: Forgotten History)
