Apollo–Soyuz: when American astronauts and Soviet cosmonauts shook hands in space

In May 1972, US President Richard Nixon and Soviet Premier Alexei Kosygin signed an agreement in Moscow paving the way for the historic Apollo–Soyuz mission. The Americans officially called the mission the Apollo–Soyuz Test Project (ASTP) while the Soviets named it Experimental flight "Soyuz"–"Apollo."

Working in Soyuz simulators and mock-ups -

Besides the Apollo Command Module, the crewmen also trained in the docking module, Soyuz simulators and mock-ups, and continued training in each other's languages, including spacecraft-to-spacecraft communications. They also received briefings on the science experiments planned for their joint mission.

Facing the press -

As the launch date approached, the crews held a press conference at the Kennedy Space Center in Cape Canaveral, Florida. They provided an overview of their mission to the media and were feted during a farewell reception. The cosmonauts departed Houston on March 1 to return to the Soviet Union. The crews would meet one more time before their historic mission, at Star City near Moscow in late April.

A call from the president -

During the first exchange between the astronauts and the cosmonauts, the crews received a telephone call from US President Gerald Ford congratulating them on the historic achievement. They were also read a statement from Soviet General Secretary Leonid Brezhnev.

Joint effort -

While the two ships were docked 137 miles (222 km) above the Earth's surface, the three Americans and two Soviets conducted joint scientific experiments.

Facing each other -

Flags and gifts were exchanged, and Alexei Leonov, the Soviet mission commander, even found time to sketch a portrait of his American counterpart, Thomas Stafford.

Overcoming the language barrier -

The crews visited each other's ships, ate together, and conversed the best they could in each other's languages.

Role reversal -

One of the more delicate technical procedures were the docking and redocking maneuvers, during which the two spacecraft reversed roles and the Soyuz became the "active" ship.

Separate ways -

After 44 hours together, the two ships separated and went their separate ways. However, both remained in orbit, the Apollo craft for a further five days, the Soviet ship for two.

Mission accomplished -

The Soviet cosmonauts soft-landed near Baikonur on July 21, 1975. Photographers were on hand to capture the moment for posterity as Valery Kubasov autographed the Soyuz-19 space capsule.

Splashdown -

The ASTP Apollo command module splashed down in the Pacific Ocean west of Hawaii on July 24, 1975, ending the American crew's historic nine-day mission into space.

Reunion -

On July 16, 2010, Valery Kubasov, Thomas Stafford, and Vance Brand reunited with one another at the New York Stock Exchange in honor of the 35th anniversary of the mission.

Museum pieces -

Scale models of the joined Apollo and Soyuz spaceships can be admired at the National Air and Space Museum in Washington, D.C. and at the RKK Energia Museum near Moscow.

Emblematic of success -

This is the official emblem of the Apollo-Soyuz Test Project, chosen by NASA and the Soviet Academy of Sciences. The badge features the words Apollo, in English, and Soyuz, which actually means "union" in Russian.

Apollo–Soyuz: when American astronauts and Soviet cosmonauts shook hands in space

Remembering the historic linkup in space

11/03/25 | StarsInsider

LIFESTYLE Science

In an unpredictable era that has seen the Cold War rekindled, it's worth remembering a remarkable event that took place 50 years ago when the first crewed international space mission, carried out jointly by the United States and the Soviet Union, took place. It resulted in an historic handshake in space that was televised around the world.

The purpose and catalyst of what was known as the Apollo–Soyuz Test Project was the policy of détente between the two superpowers. It briefly united two different countries and two different ideologies. Half a century later, however, relations between America and Russia are at their lowest point since the Cold War.

Click through the following gallery and be reminded of that extraordinary moment in 1975 high above the Earth.
