The oldest and most seasoned spacewoman, Peggy Whitson broke Sunita William's record for the most spacewalks performed by a woman.
It was the eighth spacewalk of her career as Whitson floated out of ISS to set up a new parking spot on 30th March 2017.
Whitson and her spacewalking partner, station commander Shane Kimbrough, ventured out to complete prep work on a docking port.
The spacewalkers needed to hook up vital heater cables to the docking port and install shields to protect against strikes by micrometeorites.
This will serve as the second of two docking ports for the future SpaceX and Boeing crew capsules.
SpaceX will launch the final piece of this particular port later this year or early next year.
Whitson surpassed the current record for women of 50 hours and 40 minutes of total accumulated spacewalking time, held by former space station resident Sunita Williams.
Williams is one of four NASA astronauts who will make the initial test flights of the SpaceX Crew Dragon and Boeing Starliner capsules.
57-year-old Whitson has been in orbit since November. This is her third space station stint.
Altogether, she's spent more than 500 days off the planet, also more than any other woman.
