The trio have now performed extravehicular activities on four occasions since they were launched into space in November 2022, setting a domestic record for the most spacewalks by a single crew.

During the latest extravehicular mission, they installed several items of equipment, including the extravehicular extended pump sets, the cross-module cables, and supporting devices for the extravehicular payload platform, laying a foundation for carrying out subsequent large-scale science and technology experiments outside the space station, the agency noted in a statement.
