One of the astronauts was Steve Swanson, who chose to team up with students at Boise State University for interactive opportunities before heading up to the ISS. It's a part of a program which NASA does with schools around the country to get students interested in STEM fields.
During the more than 20 minute live stream students with Space Broncos asked questions related to current experiments on the ISS. This included mini satellites, and even a veggie experiment meant to see how food grows in space.
Swanson admitted that even though he's been to space several times, there are things that he always has to get used to every time he goes up.
"For me, every time I come up I just have to get used to just floating in space again. My body has to get used to floating in space again," said Swanson.
Swanson's parents were also on hand for the event.
Students will continue to keep in contact with Swanson throughout his mission.
He is set to become commander of the ISS in a couple of weeks.
