Sending humans into space is very difficult. Astronauts need air, food, and some special protection. There are plenty more difficulties besides these, and if anything goes wrong, astronauts are a long way from home. With such difficulties, is it really worth it, especially as uncrewed missions（无人探测任务）have already been there? What’s your view—is it OK to send humans to space?
Yes—humans offer something special
Sending people into space feels more magical than just sending machines. The idea of people travelling to places no one has been to before is inspiring（令人鼓舞的）. Some people think humans will live on other planets one day, so it is necessary to get used to the difficulties of space. Besides, uncrewed missions will never create the same excitement as human astronauts. What’s more, humans make different observations（观察）from those of machines, and can talk about their experiences. Their stories and the descriptions of what they’ve done are more believable than a robot’s report.
No—it’s much safer to send robots
Humans are more important than machines, and it takes care and money to keep them alive in space. For example, machines don’t need food or air and don’t age in the same way people do. It’s far safer to send uncrewed missions on risky tasks. Are humans’ descriptions really so much more valuable than a computer’s observations? After all, uncrewed missions into space have made unbelievable discoveries and traveled huge distances. Machines can also survive conditions that humans couldn’t, such as extreme（极端的）heat. Machines have landed on the surface of Venus, where the average surface temperature is 464℃.
