CAPE CANAVERAL, FL -- Astronauts on the International Space Station completed a spacewalk Sunday despite the appearance of water inside an astronaut's helmet, NASA reported. <\/p>\n
In a tweet, the space agency said astronaut Terry Virts experienced water inside his helmet, just as he did Wednesday, but \"it's a known issue; no concern.\" <\/p>\n
The spacewalk lasted five hours and 38 minutes, NASA said. <\/p>\n
\"Crews have now spent a total of 1,171 hours and 29 minutes conducting space station assembly and maintenance during 187 spacewalks,\" the agency said in a release. <\/p>\n
NASA previously said the suit worn by NASA astronaut Virts has a history of \"sublimator water carryover.\" Water in the sublimator cooling component can condense when the suit is repressurized after a spacewalk, causing a small amount of water to push into the helmet, NASA said. <\/p>\n
NASA said International Space Station managers had \"a high degree of confidence\" in the suit. <\/p>\n
On the upcoming spacewalk, Virts and Barry Wilmore installed antennas to provide data to visiting vehicles and deploy 400 feet of cable along the edge of the station. <\/p>\n
Virts said he first noticed traces of fluid and dampness in his helmet Wednesday while he was waiting for the crew lock cabin to repressurize. <\/p>\n
He and Wilmore had been outside the space station for nearly seven hours working on the station's robotic arm and performing some maintenance. <\/p>\n
Virts immediately alerted fellow astronaut Samantha Cristoforetti about the water, and she alerted Mission Control in Houston.<\/p>\n
