What Hype is tracking

The EVA reinforces Tiangong's operational tempo: two astronauts spent about six hours outside the station on the mission's fourth series of spacewalks, demonstrating repeatable on-orbit maintenance and assembly capability and extending station sustainment.
This activity builds on recent on-orbit support and autonomy developments — including the deployment of an AI system for autonomous EVA planning and prior long-duration EVAs used to reinforce debris protection — and is enabled by resupply missions such as Tianzhou-9's delivery of EVA gear and supplies.
