Excerpt: 1973 saw the launch of the first and only American Space station known as Skylab on a Saturn INT rocket. This is a list of spaceflights launched in 1973. Proton ( ) (formal designation: UR-500) is an expendable launch system used for both commercial and Russian government space launches. The first Proton rocket was launched in 1965 and the launch system is still in use as of 2011, which makes it one of the most successful heavy boosters in the history of spaceflight. All Protons are built at the Khrunichev plant in Moscow, and then transported for launch to the Baikonur Cosmodrome, where they are brought to the launch pad horizontally and then raised into vertical position for launch. Like many Soviet boosters, the names of recurring payloads became associated with their launchers. Thusly, the moniker "Proton" originates from a series of large scientific Proton satellites, which were among the rocket's first payloads. It is also known as the D-1/D-1e or SL-12/SL-13. Launch capacity to low Earth orbit is about 22 tonnes (49,000 lb). Geostationary transfer c...
