Baikonur Cosmodrome: Russia’s Historic Space Launch Hub

Why in the News ?

A Soyuz-2.1a rocket mishap on November 27, 2025 at Baikonur Cosmodrome damaged Launch Site 31/6, halting crewed missions. Engineers are now assessing repairs, renewing focus on the spaceport’s strategic relevance, safety concerns, and Russia’s long-term dependence on Kazakhstan-based launch facilities.

Baikonur’s Origins and Global Space Legacy:

• The Baikonur Cosmodrome in Kazakhstan, operated by Russia, is the world’s oldest and largest functioning spaceport.
• Built in the 1950s as a missile testing range, it later became the heart of the Soviet space programme.
• Landmark launches include the R-7 rocket that placed Sputnik 1 into orbit in 1957, marking the start of the space age.
• In 1961, Vostok 1 carrying Yuri Gagarin, the first human in space, launched from Baikonur—cementing its historic status.
• Over decades, Baikonur has hosted launches of cosmonauts, space station modules, and planetary probes, strengthening its global scientific and geopolitical importance.

Present-Day Operations and Safety Concerns

• The spaceport hosts multiple facilities: launch complexes, assembly buildings, tracking stations, and residential areas.
• It supports major rockets such as the Proton and Soyuz, including missions to the International Space Station (ISS).
• Two major crewed-launch pads exist: Site 1 and Site 31/6, with the latter now used for regular Soyuz missions.
• Baikonur has witnessed several accidents, including the 1960 Nedelin catastrophe, where an R-16 missile explosion caused heavy casualties.
• On November 27, 2025, the Soyuz MS-28 mission led to structural damage at Site 31/6 when a falling service platform collapsed into the flame trench, forcing suspension of crewed launches.
• Russia is evaluating repairs even as it expands alternative spaceports within its territory, such as Vostochny Cosmodrome.
