ISS Canadarm2 fault forces spacewalk repair planning for Expedition 74

NASA says a section of the ISS’s Canadarm2 robotic arm broke in May, requiring repairs by spacewalking astronauts no earlier than June 30. Expedition 74 advanced biomedical and other research work while preparing for the on-orbit fix, with a spare already installed on the station.

Briefing

What Hype is tracking

Canadarm2 is central to ISS operations and payload handling; a robotic arm malfunction adds mission-critical activity to the already high-tempo maintenance cycle described in the ISS habitability/leak response, including NASA’s Dragon-shelter directive.
Expedition 74’s workplan shows how crews manage science continuity while preparing extravehicular repairs on a tight timeline, in a context where NASA has previously escalated contingency posture—see orders to prepare for a hasty departure.
The confirmation that a spare component is already on ISS constrains logistics risk and informs decision-making around EVA scheduling, repair scope, and downstream station capabilities.
