Did you know that humans haven’t walked on the lunar surface since 1972? People are planning to send astronauts to the moon again—and finally to Mars. They’ll study how long-term space travel affects humans. The possibilities are exciting. But it’s dangerous. We have plenty of technology for safely exploring(探索) space. Do we really need to send people?

We still need to send humans into space. If we don’t solve the problem of climate change, the planet could become not fit to live in. We need to find out if living on Mars is possible. The robotic missions send back a lot of information. But it won’t be enough to help us understand how we’d face on another planet.

—Elisha Lee, 11, Wilmette

As a future engineer, I believe in space technology. Robots can stay in space longer and robots’ lives are not at risk. They could stay on the moon or Mars for many years, doing research, with no danger to human life.

—Lino Marrero, 15, Frisco

Humans should continue going to space. Robots can collect information, but they can’t respond(反应灵敏) like humans in all situations. We couldn’t depend on them to develop an area that would be ▲ for humans.

—Kellen Bhatt, 11, Alpharetta

We should not send humans into space, at least not now. Sending humans into space needs a lot of money. That same money could be used for solving problems on Earth. I’m not saying that space exploration should never happen. But for now, we should focus on dealing with the problems we have on Earth.

—Samirah Horton, 13, Brooklyn
