Behnken and Hurley are currently part way through their 19-hour journey to reach the ISS, where they are expected to dock at 3.29pm UK time today.
The duo, who both joined NASA in the 2000 intake, have also made their own history this weekend.
Almost two hours after the launch on Saturday, the pair become the first to pilot a spaceship using only touchscreen controls.
The Crew Dragon capsule has ditched the clunky maze of controls seen on retired craft like the Space Shuttle or Apollo missions.
Instead, the SpaceX ship just features three large touchscreen panels.
And you can watch the former pilots navigate the Dragon towards the ISS thanks to the NASa live cam, installed in the capsule.
