Question

What were some important milestones in space travel?

Answer 1

April 12 marks two huge milestones in the history of human spaceflight. On that date in 1961, the Soviet Union's Yuri Gagarin became the first person in history to reach outer space. And exactly 20 years later, NASA launched the first space shuttle mission, debuting the workhorse vehicle that would carry astronauts to and from low-Earth orbit for the next three decades.
