What does the news item mainly talk about?
(8)The US space agency NASA has warned that astronauts on any future mission to Mars would be exposed to so much radiation getting there that they probably develop a fatal cancer. The findings come from data gathered by a NASA spaceship, the Curiosity rover. NASA’s Curiosity rover measured the radiation falling on it as it cruises through space for eight months to get the red planet. It allows scientists to put some realistic numbers on the risks astronauts would face making the same trip. They will be bombarded with damaging particle from the Sun and from deep space, raising the probability of getting a fatal cancer and developing neurological and eyesight problems. The only real solution, say researchers, is simply to get to Mars and the relative protection of its surface as quickly as possible.

B、NASA launched a new spaceship—the Curiosity rover.
