The year 1959 in science and technology involved some significant events, listed below.
Astronomy and space exploration
January 2 – Soviet spacecraft Luna 1 is launched by a Vostok rocket from the Baikonur Cosmodrome; intended to impact Earth's Moon, an error causes it instead to become the first spacecraft to fly by the Moon and the first man-made object to enter heliocentric orbit.
March 3 – Lunar probe Pioneer 4 becomes the first American object to escape dominance by Earth's gravity.
May 28 – Jupiter AM-18 rocket launches two primates, Miss Baker and Miss Able, into space from Cape Canaveral in the United States along with living microorganisms and plant seeds. Successful recovery makes them the first living beings to return safely to Earth after space flight.
June 25 – A KH-1 Corona satellite, believed to be the first operational spy satellite, is launched as science mission "Discoverer 4" from Vandenberg Air Force Base, California, aboard a Thor-Agena rocket.
August 7 – The United States launches Explorer 6 from the Atlantic Missile Range in Cape Canaveral.
September 15 – Russian probe Luna 3 sends back the first photographs of the far side of Earth's Moon.
September 19 – Giuseppe Cocconi and Philip Morrison establish the scientific rationale for SETI with the publishing of their seminal paper "Searching for Interstellar Communications" in Nature.
November 24 – Yardymli meteorite makes a landfall in Azerbaijan.
December 4 – Little Joe 2, a mission in the Mercury program, carries Sam the monkey into space.
July 17 – Paranthropus boisei (originally designated Zinjanthropus) is found in the Olduvai Gorge of Tanganyika by Mary and Louis Leakey. It dates from between 2.6 and 1.1 million BP.
First femur of Arlington Springs Man is found on Santa Rosa Island, California, by Phil C. Orr. The remains are subsequently dated to 13,000 years BP, making them potentially the oldest known human remains in North America.

Radiation doses were intense, being estimated at 205, 320, 410, 415, 422, and 433 rem.74 Of the six persons present, one died and the other five recovered after severe cases of radiation sickness.
