Three facts I learnt were that On April 12, Yuri Gagarin became the first person to make it into space. On July 20, 1969 Neil Armstrong and Buzz Aldrin became the first two people to step onto the lunar surface. And there are hundreds of Satellites that orbit earth. Two understandings I had were that human love exploring space and it must be expensive to go to space. Something I’m wondering is when will humans live on Mars?
