China conducts secretive space walk ignoring international norms

China this week revealed that two of its astronauts had conducted a secretive space walk around the Tiangong space station, marking the second extravehicular operation over the last three months.

Two members of the Shenzhou 15 crew, dubbed the “Dream Crew,” successfully exited the space station to complete “scheduled tasks” with the aid of another crew member, who remained in the cabin along with one on ground support, its space agency CMSA reported.

But the announcement came after the operation was successfully completed, which according to Space News has raised concern regarding why China’s space agency chose not to announce the latest out-of-cabin excursion.
