Two astronauts completed maintenance tasks outside the International Space Station as the world watched live on Tuesday.
Italian astronaut Luca Parmitano (European Space Agency) and U.S. astronaut Chris Cassidy (NASA) connected power lines, fixed broken parts and staged equipment that would be used to remove failed radiators, if needed, according to Florida Today.
"These are just a mixture of different, unrelated tasks, for the most part, that we're trying to burn down," spacewalk flight director David Korth, of NASA's Johnson Space Center in Houston, told reporters last week.
The astronauts wore protective spacesuits and were equipped with emergency jet backpacks, which are a safety precaution that allows the duo the ability to fly back if the safety tethers were to break.
"Life is good," Cassidy told the live viewers as the two headed into the last minutes of their excursion.
"Couldn't be better," Parmitano responded.
NASA Mission Commentator Rob Navias said the two worked "with maximum efficiency," and the team was preparing for their next Tuesday's spacewalk.
The spacewalk was reportedly the 170th conducted in the assembly and maintenance of the station, according to Florida Today. It was also the fifth for Cassidy, the leader of the excursion, wearing the red stripes on his spacesuit.
For Parmitano, it was his first spacewalk ever, and is also the first ever for an Italian astronaut.
Both astronauts were eager to go on the excursion, and Cassidy recalled his first spacewalk.
"I remember distinctly the feeling the first time I opened the hatch and looking down at the planet," Cassidy said in a NASA interview. "I remember thinking, wow, holy cow, I'm really here!"
Cassidy and Parmitano are set for another 6 ½ hour excursion at 8:10 a.m. EDT on July 16, where they will continue their work on the space station. You can watch the live spacewalk, here.
