Two NASA astronauts completed a spacewalk on Sunday outside the International Space Station (ISS) despite the appearance of water inside the helmet of one of them.
The American space agency announced the news of a successful spacewalk by its astronauts Terry Virts and Barry Wilmore on the micro-blogging site Twitter.
According to the space agency, the spacewalk outside the space station lasted five hours and 38 minutes.
“Crews have now spent a total of 1,171 hours and 29 minutes conducting space station assembly and maintenance during 187 spacewalks,” NASA said in a news release.
In a tweet, the space agency said Virts again witnessed water inside his helmet as he experienced during his previous spacewalk on Wednesday. The agency, however, allayed the fear of any known threat.
The NASA scientists had earlier said that the suit worn by Virts holds a “sublimator water carryover” history. Water present in the sublimator cooling component can begin condensing when the suit is repressurized following a spacewalk and can cause a little amount of water to push into helmet, NASA explained.
NASA, however, continued to impose trust on the suit, saying the managers at International Space Station had “a high degree of confidence”.
During the spacewalk, Wilmore and Virts installed antennas meant for providing data to the visiting vehicles and also deployed 400 feet of cable along the edge of the space station.
