1964 in science

The year 1964 in science and technology involved some significant events, listed below.

Astronomy and space exploration

• January 30 – The Soviet Union launches the first Elektron satellites.
• Spring – First recognition of cosmic microwave background radiation as a detectable phenomenon.<ref>In a brief paper by Soviet astrophysicists A. G. Doroshkevich and Igor Novikov. Template:Cite web</ref> The discovery and confirmation of the Cosmic microwave background in 1964 secured the Big Bang as the best theory of the origin and evolution of the universe.
• March 20 – The precursor of the European Space Agency, ESRO (European Space Research Organization) is established (under an agreement of June 14, 1962).
• July 31 – Ranger program: Ranger 7 sends back the first close-up photographs of the Moon; images are 1,000 times clearer than anything ever seen from Earth-bound telescopes.
• October 12 – The Soviet Union launches the Voskhod 1 into Earth orbit as the first spacecraft with a multi-person crew and the first flight without space suits (the crew wouldn't fit in the space capsule otherwise).
