Soyuz TM-21 - First Shuttle -MIR docking FLOWN cover - Norman Thagard

Soyuz TM-21 / Mir-18 — Mir-Flown Cover Signed by Thagard, Dezhurov and Strekalov

A historic space-flown cover carried aboard the Mir space station during the pioneering Soyuz TM-21 and Mir-18 expedition, hand-signed by the complete three-person crew:

• Norman E. Thagard — NASA astronaut and research cosmonaut
• Vladimir N. Dezhurov — Soyuz TM-21 and Mir-18 commander
• Gennady M. Strekalov — flight engineer

The cover features an attractive printed Soyuz TM-21 mission emblem and was cancelled aboard Mir on May 11, 1995, while Thagard, Dezhurov and Strekalov were living and working aboard the Russian orbital station.

Norman Thagard’s historic Soyuz flight

Soyuz TM-21 launched from the Baikonur Cosmodrome on March 14, 1995, carrying the three members of the Mir-18 expedition. With that launch, Norman Thagard became the first American astronaut to launch into space aboard a Russian spacecraft.

Thagard’s presence aboard Mir represented a major turning point in relations between the American and Russian space programs. Only a few years after the end of the Cold War, an American astronaut was living aboard a Russian space station, launching with Russian cosmonauts and participating in a joint scientific program.

The Mir-18 crew conducted medical and life-sciences research focused particularly on the effects of long-duration weightlessness. They also helped prepare Mir for the arrival of the Spektr research module and for the forthcoming first docking by an American Space Shuttle.

The crew that welcomed the first Space Shuttle to Mir

The Soyuz TM-21 crew played a central role in one of the defining achievements of the Shuttle–Mir program.

On June 29, 1995, Space Shuttle Atlantis docked with Mir during mission STS-71—the first docking between a Space Shuttle and the Russian station. The joined spacecraft formed what was then the largest orbital complex ever assembled and briefly brought ten astronauts and cosmonauts together in a single connected spacecraft.

Thagard, Dezhurov and Strekalov subsequently returned to Earth aboard Atlantis on July 7, 1995, while replacement cosmonauts Anatoly Solovyev and Nikolai Budarin remained aboard Mir. This was also the first exchange of a Mir resident crew using the Space Shuttle.

Thagard completed approximately 115 days in space, establishing a new American space-endurance record at the time. His mission demonstrated that American astronauts could train, launch and operate successfully within the Russian spaceflight system—experience that later proved invaluable in the development and operation of the International Space Station.

A landmark artifact of American–Russian cooperation

This exceptional cover combines several important elements:

• Flown aboard the Mir space station
• Postmarked in orbit on May 11, 1995
• Hand-signed by the complete Soyuz TM-21 crew
• Includes Norman Thagard, the first American launched aboard a Russian spacecraft
• Signed by Mir-18 commander Vladimir Dezhurov
• Signed by veteran cosmonaut Gennady Strekalov
• Attractive printed Soyuz TM-21 mission emblem
• Directly associated with the preparations for the first Shuttle–Mir docking
• Connected with the historic STS-71 crew exchange

A highly desirable artifact from the opening chapter of the Shuttle–Mir partnership, documenting the mission that placed an American aboard Mir and helped pave the way for the first Shuttle docking and the later International Space Station.
