• Soviet Union: The USSR issued numerous stamps to celebrate milestones in space exploration, such as the launch of Sputnik 1 (the first artificial satellite) in 1957, and Yuri Gagarin, the first human in space, in 1961.
• United States: NASA’s achievements are frequently commemorated. Early stamps include the Project Mercury missions (John Glenn’s orbit of Earth), and Apollo 11, celebrating the first human landing on the Moon in 1969.

2. Astronauts and Cosmonauts

• Similarly, Russian cosmonauts such as Gagarin and Valentina Tereshkova, the first woman in space, have appeared on stamps in multiple nations.

3. Spacecraft and Missions

• Stamps often feature iconic spacecraft like Apollo, Soyuz, Space Shuttle, Voyager, and Mars rovers. For example, the U.S. released a series of stamps honoring the Space Shuttle missions.
• Robotic space exploration has also been commemorated with stamps featuring probes like Pioneer, Voyager, and Curiosity.

4. Space Agencies and Collaborations

• The anniversaries of space agencies, such as NASA’s 60th anniversary in 2018, are often marked with commemorative stamps.

7. Futuristic Space Exploration

• Some stamps depict futuristic visions of space travel, space colonies, and exploration beyond our solar system, offering a glimpse of what future space missions might entail.

Stamp collecting related to outer space is a popular niche, with some rare issues becoming valuable over time, especially those tied to historical space events.
