16 March 1926 · 100 years ago

Robert Goddard launched the first liquid-fuelled rocket

After failing to secure an army contract during the First World War, Goddard proceeded with private funding and flew the world's first liquid-fuelled rocket on 16 March 1926 in Massachusetts. The flight lasted only a few seconds and reached a modest height, but liquid propulsion became the basis of every large launch vehicle that followed, from the V-2 to today's orbital rockets.

June 1944 · 82 years ago

Germany launched the V-2, the first man-made object to reach space

The V-2, the first guided ballistic missile, was developed as a weapon for use against London and Antwerp, but on a test flight in June 1944 one reached an altitude of 189 kilometres, above the Kármán line. By the minimum criterion of launching an object beyond the Kármán line, Germany thereby became the first spacefaring nation, and its lead engineers later shaped both the American and Soviet rocket programmes.

United States and Soviet Union divided the V-2 rocket team and production facilities after the war

Most of the V-2 team, including Wernher von Braun, surrendered to the United States and was moved to work on American missiles at what became the Army Ballistic Missile Agency, yielding Juno I and Atlas. The Soviet Union captured V-2 production facilities and built replicas, seeding both superpowers' launch industries.

1950s · 76 years ago

Soviet Union developed intercontinental ballistic missiles that became its launch vehicles

ICBMs were built to carry nuclear weapons as a counter to US bombers, with Sergey Korolev as chief designer. Derivatives of his R-7 Semyorka missile became the world's first orbital launch vehicles, tying space access to military missile programmes.

12 April 1961 · 65 years ago

Yuri Gagarin became the first human to reach orbit

On 12 April 1961 the Soviet Vostok 1 mission carried Yuri Gagarin through one orbit of the Earth, the first human spaceflight.
