Astronaut Scott Kelly may be drawing most of the world's attention, but he's not the only American to recently return to Earth after a stint aboard the International Space Station. Flight engineer Kjell Lindgren spent five months up there and returned in December. And—just to make sure you don't forget it—he's tapping into the most fearsome wellspring of power science has at its disposal: the devastating cuteness of kindergarteners.

In this video, Lindgren brings all of his finely-honed, NASA-sponsored scientific expertise to bear on burning questions like, "Have you seen an alien? Because I really want to see a picture of one."

Now, if this video was a Q&A with adults, it probably would have looked something like this:

“So, Kjell, what was it like to spend a year in space?”

“That wasn’t me.”

“How is your health different from your twin?”

“...Again, that’s the other guy.”"

But for Lindgren, the great thing about kindergarteners is that they don't really know or care who Scott Kelly is. For the rest of us, it's that their giddy enthusiasm for science (and life in general) is adorable. And that they'll ask the obvious questions we all secretly wonder about.

Lindgren's not bad either: In the span of three minutes, he jumps from the Aurora Borealis to a recipe for astronaut cheeseburgers that sounds like something a drunk frat boy would come up with. So whether you're here for cute kids or to discreetly figure out how the ISS stays aloft, this clip should do the trick.
