Two NASA astronauts completed the 13th spacewalk at the International Space Station ISS this year, the agency said, days after the event was postponed due to a debris risk.
Astronauts Thomas Marshburn and Kayla Barron walked outside the space laboratory on Thursday, replacing a faulty antenna and restoring its capability.
It was awesome! Barron said after completing her first spacewalk, she said, according to a tweet posted by NASA.
The US agency said that the astronauts returned to the station after six hours and 32 minutes and did some get-ahead tasks for future spacewalks.
The spacewalk, scheduled to take place on Tuesday, was postponed after NASA received a debris notification for the orbital outpost.
The agency said in a statement that Houston experts are assessing a fresh risk from orbital rocket debris that may pass close to the ISS on Friday.
Mission Control is working with NASA's international partners to prepare for a possible debris avoidance maneuver.
Marshburn was caught on the robotic arm by NASA to move around the ISS before getting to work on the antenna.
The spacewalk was the fifth for the astronaut, a doctor who flew aboard a Space Shuttle in 2009 and a Russian Soyuz spacecraft in a 2012 -- 13 mission.
Barron, who was selected to the NASA astronaut corps in 2017, previously served as a submarine warfare officer for the US Navy.
The pair arrived at the ISS on November 11 aboard SpaceX's Crew Dragon Endurance with NASA's Crew 3 mission for a six-month stay.
The ISS has had 21 years of continuous human presence this month, NASA said on its website.
They said it had hosted 249 people from 19 nations who had taken part in thousands of research projects during that period.
