题目内容
Since 1936, many female space explorers have followed Russian astronaut Valentina Tereshkova. Let’s look at the missions（任务）of four important female astronauts to find out what astronauts do in space.
In 1983, Sally Ride became the first American women in space. Her team carried out scientific experiments in space and put two communications satellites in space. Satellites make it possible for us to communicate instantly with each other across the world through TV, radio, and telephones.
In 1984, Kathryn Sullivan became the first American women to walk in space. During her mission, she discovered important information about the sun’s energy and how it affects the climate in very hot and very cold places on Earth. She also took photographs of Earth and measured air pollution.
In 1992, Mae Jemison became the first African-American in space. During her mission, she did scientific experiments using the weightless atmosphere. In space, there is no gravity, so everything floats! Dr. Jemison’s experiments gave important information about the human body to produce better medicines and healthcare.
In 2012, Liu Yang became the first Chinese women in space. She did experiments in space medicine, which look at how astronauts can survive and stay healthy in space. The conditions in space are very hard on the body and space medicine helps astronauts work safely.
