It's always a good day when you're in outer space at work and you get a call from the Vice President of the United States! In a video exclusively released by Marie Claire, Vice President Kamala Harris, who is currently on a six-month scheduled stay on the International Space Station (ISS) in honor of Women's History Month She chatted with NASA astronauts Shannon Walker (opens in new tab) and Kate Rubins (opens in new tab).

"Greetings from the White House. I'm here now," Vice President Harris says excitedly at the beginning of the video. The Vice President then asks Astronauts Walker and Rubins to tell viewers what they are currently studying in space. Astronaut Walker, who has a Ph.D. in astrophysics, is working on a free-floating satellite that will help in future lunar and Mars missions (!). He explains that he is working on a free-floating satellite and that he is studying hundreds of worms to see how muscle strength changes in space.

"I don't think any of us really thought we would become astronauts," Astronaut Rubins, the first person to sequence DNA in space, tells Vice President Harris. So I would encourage anyone who wants to become an astronaut not to hold themselves back. All of our crew members do it because they love what they do. We love every minute of it."

At the end of the video, Vice President Harris thanked the astronauts and extended an invitation to them to visit the White House "when their feet hit the ground. Casually.
