Space Mission Milestones
Landmark missions in the history of space exploration.
Milestones in space exploration from Sputnik 1 to the James Webb Space Telescope, each with its year and what it achieved. Added entries cover the first human in space, first Moon landings and orbits, the first planetary landers, comet landing, rovers and helicopter flight, and the Artemis I test flight.
Use it when
- You need a dated list of firsts in spaceflight and space science.
- You are building a timeline of exploration.
Watch out for
- The year is that of the headline achievement, which can differ from the launch year.
- 'First' claims are specific: for example, the first human in space was Yuri Gagarin in 1961 and the first crewed lunar landing was Apollo 11 in 1969.
