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.
Japan and China each launched their first satellites in 1970, bringing the total number of nations with independent launch capability to five.
Explorer 1 was the first American satellite to reach orbit on 31 January 1958.
1972 saw humanity's last crewed mission to the Moon of the 20th century, Apollo 17.
1973 saw the launch of the first American Space station known as Skylab on a Saturn 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.
This article outlines notable events occurring in 1994 in spaceflight, including major launches and EVAs.
On March 29, 1974 Mariner 10 became the first spacecraft to fly by Mercury, that saw a spacecraft for the first and last time in the 20th century.

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.
