TWO astronaut NASA performs a spacewalk mission or space trip to replace a faulty antenna in International Space Station (ISS), Thursday (2/12/2021). The mission was delayed to avoid the risk posed by orbital debris from Russia’s missile test a few weeks ago.
The planned 6.5-hour space journey begins at 07:10 AM. Two NASA astronauts Thomas Marshburn and Kayla Barron exit the ISS research laboratory orbiting 250 miles (400 km) above Earth.
The start of extra-vehicular activity (EVA) after a 48-hour delay to avoid risks posed by orbital debris from Russian missile tests. The origin of the debris is unclear by NASA, although a spokesman said there was no indication it was from the debris of the satellite that was destroyed by Russia.
The spacewalk is the fifth for Marshburn, (61), a medical doctor and former aviation surgeon and the first for Barron, (34), a US Navy submarine officer and spaceflight nuclear engineer.
Their task was to remove the faulty S-band radio communications antenna assembly, now more than 20 years old, and replace it with a spare one stored aboard the space station.
