The year 1966 saw the peak and the end of the Gemini program. The program proved that docking in space and human EVA's could be done safely. It saw the first launch of the Saturn IB rocket, an important step in the Apollo program, and the launch of Luna 9, the first spacecraft to make a soft landing on a celestial object.
The year 1967 in spaceflight saw the most orbital launches of the 20th century and more than any other year until 2021, including that of the first Australian satellite, WRESAT, which was launched from the Woomera Test Range atop an American Sparta rocket. The United States National Space Science Data Center catalogued 172 spacecraft placed into orbit by launches which occurred in 1967.
The United States National Space Science Data Center catalogued 157 spacecraft placed into orbit by launches which occurred in 1968. The first crewed Apollo missions occurred in 1968. It was also the year in which Earth lifeforms first left low Earth orbit, during the successful Zond 5 mission to the Moon and the Zond 6 lunar mission which crashed upon return, and the year that humans first left low Earth orbit, during the successful Apollo 8 mission to the Moon.
1969 saw humanity step onto another world for the first time. On 20 July 1969, the Apollo 11 Lunar Module, Eagle, landed on the Moon's surface with two astronauts aboard. Days later the crew of three returned safely to Earth, satisfying U.S. President John F. Kennedy's 1962 challenge of 25 May 1961, that "this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth."
Japan and China each launched their first satellites in 1970, bringing the total number of nations with independent launch capability to five.
Luna 1 was the first spacecraft to leave the gravitational influence of Earth. Also in 1959, Luna 2 was the first spacecraft to reach the surface of another celestial body, impacting the Moon, and Luna 3 returned the first images of the far side of the Moon.
Explorer 1 was the first American satellite to reach orbit on 31 January 1958.
1973 saw the launch of the first American Space station known as Skylab on a Saturn V rocket.

The year 1986 saw the destruction of Space Shuttle Challenger shortly after lift-off, killing all seven aboard, the first in-flight deaths of American astronauts. This accident followed the successful flight of Columbia just weeks earlier, and dealt a major setback to the U.S. crewed space program, suspending the Shuttle program for 32 months.
The following is an outline of 1989 in spaceflight.
In 1975, several notable events occurred in spaceflight, including the launches of Venera 9 and 10 and their Venus arrivals, the launches of the Viking Mars missions, the joint American-Soviet Apollo–Soyuz Test Project (ASTP), the failure of Soyuz 7K-T 39, and the launch of Aryabhatta, India's first satellite.
1978 saw the launch of the Pioneer Venus missions launched by the United States, on 20 May and 8 August. The Pioneer Venus Multiprobe landed four spacecraft on the planet, one of which transmitted data for 67 minutes before being destroyed by atmospheric pressure. ISEE-C, which was launched on 8 December, flew past comet 21P/Giacobini–Zinner in 1985, and Halley's Comet in 1986.
