We were headed toward a branch of an access backbone, which was a space for moving cargo to and from the port and between station levels, and was also an access and transport system for station engineering bots and teams. There were strips of emergency lighting here and lots of marker paint, giving off bursts of light and feed signals, mostly temporary instructions and guides for bots and human workers. Mensah’s grip on my jacket relaxed and I could tell from her breathing the light was a relief.
