NASA astronauts Thomas Marshburn and Kayla Barron on Thursday will leave the confines of the International Space Station to conduct the spacewalk in order to repair a faulty communications antenna.
The spacewalk had previously been scheduled for Tuesday, but was called off the night before after NASA received a debris notification for the International Space Station.
The repair is expected to last about six hours and 30 minutes and the event marks the first spacewalk for Barron, as well as Expedition 66, NASA said.
