📖 课文原文 · LIVING IN SPACE
Stephen Hawking, one of the world’s most famous scientists, believed that to survive, humans will one day have to move into space. “Once we spread out into space and establish independent colonies, our future should be safe,” he said. Today, the United States, Europe, Russia, China, and Japan are all planning to send astronauts back to Earth’s closest neighbor: the moon. Some of these countries want to create space stations there within the next 10 years. These stations will prepare humans to visit and later live on Mars or other Earthlike planets.
Robert Zubrin, a rocket scientist, thinks humans should colonize space. He wants to start with Mars. Why? He thinks sending people to Mars will allow us to learn a lot of things—for example, the ability of humans to live in a very different environment. Eventually, we could create new human societies on other planets. In addition, any advances we make in the fields of science, technology, medicine, and health will benefit people here on Earth.
SpaceX is a company that builds rockets. Its founder and CEO, Elon Musk, also believes we should colonize Mars. He doesn’t want to send just “one little mission,” though. He wants to build a full city on the Red Planet with a million people. Living in space may sound like science fiction, but with the rapid pace of technology, it may happen sooner than we think.
