Zond 5 was a spacecraft of the Soviet Zond program. In September 1968 it became the first spaceship to travel to and circle the Moon in a circumlunar trajectory, the first Moon mission to include animals, and the first to return safely to Earth. Zond 5 carried the first terrestrial organisms to the vicinity of the Moon, including two tortoises, fruit fly eggs, and plants. The Russian tortoises underwent biological changes during the flight, but it was concluded that the changes were primarily due to starvation and that they were little affected by space travel.
Zond 6 was a formal member of the Soviet Zond program, and an unpiloted version of the Soyuz 7K-L1 crewed Moon-flyby spacecraft. It was launched on a lunar flyby mission on November 10, 1968, from a parent satellite (68-101B) in Earth parking orbit. The spacecraft carried a biological payload of turtles, flies, and bacteria. It also carried scientific probes including cosmic ray, micrometeoroid detectors, and photographic equipment.
This is the timeline of known spaceflights, both crewed and uncrewed, sorted chronologically by launch date. Owing to its large size, the timeline is split into smaller articles, one for each year since 1951. There is a separate list for all flights that occurred before 1951.
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.
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.
1972 saw humanity's last crewed mission to the Moon of the 20th century, Apollo 17.
This article outlines notable events occurring in 2003 in spaceflight, including major launches and EVAs.
The following is an outline of 1981 in spaceflight.
The following is an outline of 1983 in spaceflight.
This article outlines notable events occurring in 1994 in spaceflight, including major launches and EVAs.
Spaceflight in 1977 included some important events such as the roll out of the Space Shuttle orbiter, Voyager 1 and Voyager space probes were launched. NASA received the Space Shuttle orbiter later named Enterprise, on 14 January. This unpowered sub-orbital space plane was launched off the top of a modified 747 and was flown uncrewed until 13 August until a human crew landed the Enterprise for the first time.
In 1975 several notable events happened in spaceflight such as the launch and arrival at Venus of Venera 9 and 10, the launch to Mars of the Viking orbiter/landers missions, the joint Apollo–Soyuz Test Project, and the launch of satellite Aryabhatta.
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.
This is a list of spaceflights launched between January and June 1961. For launches between July and December, see 1961 in spaceflight (July–December). For an overview of the whole year, see 1961 in spaceflight.
