Ukrainian orbital launch vehicle. Version of the Zenit-3SL modified for launch from existing ground facilities at Baikonur, using the common Zenit-2SB core vehicle with an upper stage Block DM-SLB designed by RSC Energia (Russia) and a new payload fairing designed by NPO Lavochkin (Russia).

The Sea Launch Board of Directors voted on September 30, 2003, to offer launch services from Baikonur Cosmodrome in Kazakhstan, in addition to its sea-based launches at the Equator. The new offering, Land Launch, was based on the collaboration of Sea Launch Company and Space International Services, of Russia, to meet the launch needs of commercial customers with medium weight satellites.

The Land Launch system uses a version of the Sea Launch Zenit-3SL rocket, the Zenit 3SLB, to lift commercial satellites in the 2,000 to 3,500-kilogram range to GTO and heavier payloads to inclined or lower orbits. The three stages on the Zenit 3SLB were the same as those on the Sea Launch Zenit-3SL, with the only significant difference between two being the fairing. A two-stage configuration of the same rocket, the Zenit 2SLB, was also available for launching heavy payloads, or groups of payloads, to LEO. Payloads and vehicles would be processed and launched from existing Zenit facilities at the Baikonur launch site. The first Land Launch mission, carrying the PAS-11 satellite for PanAmSat, was scheduled for the second quarter of 2007.12 Expanding on its Sea Launch marketing efforts, Boeing Launch Services, Inc., managed marketing and sales for this new offering.

  • Zenit Zenit was to be a modular new generation medium Soviet launch vehicle, replacing the various ICBM-derived launch vehicles in use since the 1960's (Tsiklon and Soyuz). A version of the first stage was used as strap-ons for the cancelled Energia heavy booster. But it was built by Yuzhnoye in the Ukraine; when the Soviet Union broke up planned large-scale production for the Soviet military was abandoned (Angara development was begun as an indigenous alternative). Launch pads were completed only at Baikonur; those at Plesetsk were never finished and are planned to be completed as Angara pads. However the vehicle found new life as a commercial launch vehicle, launched from a sea platform by an American/Ukrainian consortium. More...

  • Baikonur Russia's largest cosmodrome, the only one used for manned launches and with facilities for the larger Proton, N1, and Energia launch vehicles. The spaceport ended up on foreign soil after the break-up of Soviet Union. The official designations NIIP-5 and GIK-5 are used in official Soviet histories. It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.
