NASA astronauts complete spacewalk which was postponed due to debris risk .
Two NASA astronauts completed an hours-long spacewalk on Thursday morning that was earlier postponed due to a risk of space debris.
Astronauts Thomas Marshburn and Kayla Barron left the hatch at 6:15 a.m. EST and successfully conducted a spacewalk that lasted 6 hours and 32 minutes to replace a faulty antenna.
The duo replaced "a degrading SASA unit with a spare onboard," NASA tweeted.
The spacewalk ended at 12:47 p.m. EST with both the astronauts back in the hatch.
