Order These Space Exploration Milestones

Place these landmark events in space exploration history in the correct chronological order. The space age began with a Soviet beep heard around the world - Sputnik's launch in 1957 - And has accelerated ever since. In the decades that followed, humanity sent the first humans to orbit, walked on the Moon, dispatched robotic probes to the edges of the solar system, built a permanent international space station, and began the era of commercial spaceflight. Each milestone built on the last: Yuri Gagarin's orbit inspired the Mercury and Gemini programs, which enabled Apollo 11's historic Moon landing. Later achievements like the Hubble Space Telescope, Mars rovers, and the James Webb Space Telescope have expanded our view of the cosmos beyond what the early pioneers could have imagined. Order these milestones and test your space history.
