However, the cognitive effects of long-term space travel are less well documented. New research has looked at the cognitive performance of 25 astronauts during their time on the International Space Station (ISS). The team put the astronauts through the same set of 10 tests both on Earth and on the ISS. These were repeated once before, twice during, and twice after the mission, within 10 and 30 days of landing. The researchers found that the astronauts took longer to complete tests measuring processing speed, working memory and attention on the ISS than on Earth, but they were just as accurate. While there was no overall cognitive harm or lasting effect on the astronauts’ abilities, some of the measures, like processing speed, took longer to return to normal after they came back to Earth. Having clear data on the cognitive effects of space travel will be crucial for future human spaceflight, says Elisa Ferrè at the University of London. “A mission to Mars is not only longer in terms of time, but also in terms of autonomy (自主性),” says Ferrè. “People there will have a completely different interaction with ground control because of distance and delays in communication, so they will need to be fully autonomous in making decisions. You definitely don't want to have astronauts on Mars with slow reaction time.” “It's not necessarily a great cause for an alarm, but it's useful to be aware so that you know your limits when you' re in these extreme environments. It's not just how you perform in those tests, but also the awareness of your ability. For instance, we know that if you lack sleep, your performance will often decline, but you won't realize your performance has declined.” says Jo Bower at the U ... ...
