After two years of hammering out details and wording, President Nixon and Soviet Premier Alexei Kosygin sign an international agreement to share science and technology between the United States and Soviet Union, including an agreement to mount a joint space mission culminating in the docking of an Apollo spacecraft and a Soyuz spacecraft in Earth orbit in 1975. Both nations’ space agencies begin crew selection and technical preparations for a joint venture that seemed impossible during the Cold War-fueled race to the moon.
ITV broadcasts the sixth and final episode of Escape Into Night, adapted by Ruth Boswell from the Catherine Storr novel Marianne Dreams. Originally shown in color, the color master tapes are lost over time, and the series survives only in black & white recordings. It is those recordings that will allow the series to resurface on DVD in the 21st century.

With planning already well underway for the Apollo-Soyuz mission which won’t take place until 1975, NASA commissions a study from McDonnell Douglas to explore the feasibility of a follow-up to the international space mission, possibly involving joining the backup of the Skylab space station (known as “Skylab B”) and a yet-to-be-launched Soviet Salyut space station at some point in the latter half of the 1970s, effectively creating a joint international space station. Although the study goes so far as to specify issues of concern regarding the structure of the two stations and their respective standard atmospheric pressures, the recommendations are shelved pending the outcome of the Apollo-Soyuz flight. Significant political developments in the late 1970s will prevent the idea of an international station from moving forward for at least a quarter century.

In Santa Clara, California, Atari is formed by Nolan Bushnell and Ted Dabney. The company is initially part of Bushnell’s desire to continue competing in the coin-operated game market, where he believes video games can take part of the market share from pinball, but consumer products are not far from Bushnell’s mind either: two weeks before Atari’s incorporation, he attends a Magnavox product fair and gets a first-hand look at the first home video game console.
The fourth Planet Of The Apes film, Conquest Of The Planet Of The Apes is released in theaters, starring Roddy McDowall, Natalie Trundy, Severn Darden, and Ricardo Montalban. The Apes film franchise shifts to a near-future setting that picks up the threads of Escape.

Space shuttle contractor North American Rockwell submits a safety study to NASA concerning safety and escape systems for the upcoming space shuttle, including a study of smaller vehicles with potential use as “lifeboats” in the event that a shuttle is unfit for return to Earth due to heat shield or other catastrophic damage. The various proposals, which include the possibility of permanently berthing an Apollo command module (another vehicle contracted to North American Rockwell) in the shuttle’s cargo bay for use as a lifeboat, are rejected by NASA due to the impact that each proposal would have on available space and weight for cargo.
En route to becoming the first human-made spacecraft to visit Jupiter, NASA’s Pioneer 10 also becomes the first human-made spacecraft to enter the asteroid belt between the orbits of Mars and Jupiter. Whether or not the spacecraft will survive this crossing is indeed one of the mission’s major experiments, and is a topic of active debate between scientists with differing views of how densely populated the asteroid belt may be. The spacecraft will survive the crossing without incident.

Originally named ERTS-1 (Earth Resource Technology Satellite), NASA’s Landsat satellite, based on the Nimbus weather satellites, is launched to begin constant observations of Earth’s land, air and oceans. Landsat 1’s tour of duty lasts just under six years, during which it discovers a previously unknown island – never before spotted from land or sea – off the northeastern Canadian coast. Landsat 1 remains in service through 1978.

In the broad daylight of mid-afternoon, an asteroid measuring somewhere between 10 and 50 feet in diameter plows through Earth’s atmosphere over North America, creating a long-tailed fireball across the sky. Undetected before its close pass – only 35 miles from Earth’s surface – asteroid US19720810 skips off of the atmosphere and back into space, having lost half of its mass to the frictional heating of plummeting through the atmosphere. The spectacle lasts only a couple of minutes, and US19720810 will make another pass by the Earth in 1997 (though not at such a close distance). 
BBC1 airs the 37th episode of Doomwatch. This episode no longer exists in the BBC’s archives. Due to its controversial content, the following episode, Sex And Violence, is never broadcast by the BBC, and production on the series is shut down before the planned 13th and final episode of the season can be filmed, effectively making Killer Doplhins the series’ broadcast swan song.

NASA launches the third and final Orbiting Astronomical Observatory satellite, given the nickname “Copernicus” when it successfully enters service near the 500th anniversary of the birth of the famed astronomer of the same name. OAO-3 is a joint venture between NASA and universities in the U.S. and the U.K., again focusing largely on ultraviolet observation of the sky, and it is instrumental in the discovery and study of long-period pulsars. OAO-3 will remain in service through February 1981, its successful nine-year mission lending weight to the ongoing construction and planning of NASA’s Space Telescope project, later to be known as the Hubble Space Telescope.
The British science fiction series Doctor Who is broadcast in the United States for the first time on WPHL, an independent commercial TV station in Philadelphia. WPHL is among the first American stations to have purchased a syndication package of Doctor Who episodes, starrring Jon Pertwee as the third Doctor, from BBC Enterprises by way of Time-Life Television. The package includes the series’ first two color seasons, plus the first story from the 1972 season (the relatively recent Day Of The Daleks). The success of Star Trek reruns in syndication may well have indie stations convinced that Doctor Who is the next big thing…
