A long way to Mars
When Alyssa Carson was 3, she said that she wanted to become an astronaut and go to Mars(火星). Over the next 17 years, she worked hard for her dream. Carson is 20 now-and in the year 2033, her dream may come true. By that time, she hopes to become a NASA(美国航空航天局) astronaut and fly to the red planet. Let's take a look at how she is getting ready for her future space journey.
At 7, Carson went to a NASA space camp in the US for the first time. There, she saw a real rocket. At 12, she visited all 14 NASA visitor centers across nine different states in the US.
When she was older, she took part in a special project where she learned more about space. . She learned about-microgravity(微重力).
- She learned how her body reacts(反应) when losing oxygen(氧气). - She learned about robotics(机器人技术) and built her own rockets. - She learned about different parts of spaceship and how spacesuit work.
·Early in 2018, Carson did some underwater training. The underwater world is very quiet. People can easily lose their sense of direction there. It is just like being in space.
