🌌 Spacewalk Progress and Ingress

This paragraph continues the narration of the spacewalk, focusing on Sarah's progress as she performs various tests. She is stepping into different positions and translating vertically, with the crew monitoring her oxygen flow and time. The script mentions a preference for horizontal bars and Sarah's ability to stabilize herself with a single hand. The crew also checks the visibility and reach from different bars on the space station. The mission specialist, Sarah Gillis, is highlighted as she completes the test matrix and provides readings from her suit, including pressure, temperature, and humidity. The communication between the crew and ground control is intermittent due to ground station coverage gaps, but the team remains in contact through satellites. As Sarah finishes her tasks, she prepares to head back inside, with the crew providing guidance and support.
