What Would You Ask An Astronaut In Space?

On Friday morning, I have a once-in-a-lifetime opportunity, thanks to our Innovations Editor here at The Huffington Post, Jake Bialer. I'll be sitting down for a chat with two NASA astronauts, Daniel Burbank and Donald Pettit. But here's the coolest part: they will be talking to me FROM SPACE.

Burbank and Pettit are currently working at the International Space Station (ISS ), which orbits the Earth 240 miles above its surface and travels at 17,500 miles per hour. So, I want to reach out to you, our readers at HuffPost Science.

What should we talk about? If you could ask an astronaut in space any question, what would it be?

Leave your questions in the comments section below, or tweet to me @CaraSantaMaria , using the hashtag #spacechat, and your question could be transmitted all the way to the ISS. Then meet us right back here at HuffPost Science on Friday, January 6th to watch the entire satellite interview.

Here's a little bit more information, straight from Houston, about the two brave astronauts that I'll be speaking with:

Daniel Burbank, a veteran of two space shuttle missions to assemble the station, will launch with Russian crewmates on a Soyuz spacecraft from Kazakhstan on Sunday, Nov. 13. Arriving at the complex on Nov. 16 for a four-month mission, Burbank will command the Expedition 30 crew through mid-March.

Donald Pettit will join Burbank in late December when he launches from Kazakhstan with Russian and European crewmates in another Soyuz spacecraft. Pettit will remain on the station for five months, returning to Earth in mid-May after serving as part of the Expedition 30 and 31 crews. He is a veteran of a long-duration mission on the station as part of the Expedition 6 crew in 2002 and 2003, as well as a subsequent space shuttle mission to assemble the station.
