ISS Spacewalk Cut Short

RobertB-DC writes "The spacewalk that was intended to replace a balky power supply ended almost before it started, according to Spaceflight Now's Mission Status Center play-by-play. The Russian Orlan spacesuit worn by US astronaut Mike Fincke developed a problem with its oxygen supply (!), forcing both spacewalkers back to the airlock after less than 15 minutes. Mission control and the ISS crew are still debating what to do next."

The American suits have been used and are preferred for spacewalks (the US airlock recycles the air which is useful).

Unfortunately when they tested the US suits shortly after getting onboard they found problems (air bubbles in the cooling system IIRC) so they had to use the Russian equipment. This meant a much more dangerous/risky spacewalk but it was the only working kit they had.

Now it is a question of which kit they can fix/replace first.

Teathers have never broken when connected to a astronaught-type in orbit. Satellites have done experiements with teathers before where those have broken but it was a completly different environment.

As for jet packs, the airlocks are not able to handle them. They would need to be mounted outside, but they would deteriorate, so they would need a locker.....and the problems keep mounting.
