The Shenzhou-13 astronauts wear a new spacesuit for their first extravehicular activities. The suit has three colors - red and yellow for the Chinese national flag, and space blue. They were carried on the Tianzhou-3 cargo craft to the space station in September. On November 2, the astronauts tried on the new suits for the first time. The chief designer of the spacesuit said the lower limb and joint parts are optimized to better fit thin astronauts. And the suit can support extravehicular activities for eight hours.
