CAPE CANAVERAL, Fla. (AP) - NASA says astronauts encountered a few snags as they undertook some plumbing work Friday on the International Space Station.
Dealing with leaking ammonia and minor glove damage caused such a delay that the astronauts had to leave a radiator job undone. But neither problem posed any danger to Kjell Lindgren or Scott Kelly, making their second spacewalk in 1 1/2 weeks. Their main job was to undo jury-rigged repairs made to a leaky cooling line three years ago.
NASA says Friday's spacewalk ended up lasting nearly eight hours, much longer than intended. It also marked Kelly's 224th consecutive day in orbit, already a U.S. record.
This was the 190th spacewalk in the station's 17-year history.
Astronauts have been on board, continuously, for 15 years.
