Here's what we learned...
They actually use the fancy ~space language~ like you see in the movies.
The Space Station has space coffee!
Kelly: "It had a little frothiness on top and everything — it was a real treat."
Virts: "It's been pretty unique to have an espresso machine... That's definitely been a pretty cool first in space."
The Space Station crew has movie nights with their new big-screen projector.
Virts also explained they get episodes of daily news broadcasts to watch and keep up with what's going on back down on planet Earth.
They also get to enjoy sports!
The astronauts said NASA will send games about a day after they happen, or if it's a day game, the Space Station might receive it later that night when they have satellite coverage.
"One of the best ways that I've connected with Earth is watching baseball... On Earth I love keeping track with some of my favorite teams, the Orioles and the Astros," said Virts.
Kelly predicts humans will set foot on Mars within the next two decades.
Do you guys see humans stepping foot on Mars in the next 50 years?
Kelly: "Oh absolutely in the next 50 years. I would like to think it'll be in the next 15 to 20 years."
The Space Station crew exercises more in space than they do on Earth.
Some astronauts come back from space stronger than when they left.
And last but not least, the crew members LOVE the observation cupola.
According to NASA, the observation cupola provides the largest set of windows ever flown in space. The windows provide the astronauts with an incredible view of planet Earth, as well as a direct view of the station's robotic operation.
Here's astronaut Terry Virts' top three views of Earth while in the observation copula:
Virts: "You could see this thing dancing around and moving... That was truly amazing."
