In the past few years, space travel has become a hot topic. Humans have always been interested in what is in space. In 1969, the Apollo 11 made history when American astronauts Neil Armstrong and Buzz Aldrin landed on the moon. They walked on the lunar surface（月球表面）, collecting rocks and taking photos. This was a small step for them, but a huge and meaningful step for people.
Now, many countries around the world are working on new space programs. Scientists want to send astronauts to Mars in the future. Mars is the fourth planet from the sun and is often called the "Red Planet" because of its red color. It has a thin atmosphere（大气层）, and the temperature there can be very low. However, it is also like the Earth in some ways, such as the changes of seasons. Space travel is not only exciting but also very challenging. Astronauts need to train for a long time to get used to the zero-gravity（失重）environment in space. Spaceships have to be carefully made to protect the astronauts from the dangers in space.
11. Who made history by landing on the moon in 1969?（不超过5个词）
12. Why is Mars sometimes considered similar to Earth?（不超过10个词）
13. What do you think is the main difficulty for humans to live on Mars?（不超过15个词）
