Hangout With an Astronaut: Ask Your Questions

Since the year of mankind’s inaugural trip to space in 1961, 341 people have crossed the celestial borders of outer space. These new-age navigators represent the pinnacle of human achievement. What is it about their daring voyages that elicit wonderment in those watching from Earth? Becoming an astronaut is a difficult, but not impossible dream. Join us for our next Google+ Hangout to discover one astronaut’s path to becoming a crew member on the International Space Station.

Astronaut Piers Sellers has participated in not one, but three missions to the International Space Station (ISS), his most recent flight in 2010. He has performed multiple space walks and eaten plenty of astronaut food. With over a month’s worth of room and board on the ISS, Piers knows better than most what it’s like to live in space.

We’re also joined by space architect, Constance Adams and planetary geologist Bethany Ehlmann — two women working to make space more habitable for humans. Bethany is part of the famed Mars Rover Curiosity team based at NASA’s Jet Propulsion Laboratory (JPL). As a geologist, she’s analyzing the surface of Mars for evidence of water and environments suitable for life. Constance also hails from NASA and specializes in designing complex expandable living areas for the International Space Station and for the surface of Mars. When humans get to the red planet, it’ll be thanks in part to work these two National Geographic Explorers have done.

Want to ask Piers what it was like to live in zero-gravity? Or ask Constance how small a box she could fit a room into? Or ask Bethany for the latest news form Mars ? Tune into our next Hangout March 20th at  2:30 p.m. EST (6:30 p.m. UTC).

    i love all the question :) i read all the comments that people put here…
    i wanna say one thing. life is not possible except on this earth. never ever. only you can use space to facilitate you on earth i.e., for a global communication. and to other people except astronaut, i will say only that there is no planet in this world like earth. soo wonder full with lovely weathers. delicious fruits, sweets, ice cream, pizza, chocolates, Mac, KFC, Subways, Spicy food ;) so try to first make a trip of the world then think to go for space.

    While viewing the ISS passing overhead one night, I saw a momentary flash of brightness from the ISS. Could this be due to the solar panels changing their configuration at the time?

    I’ve always dreamed of becoming an astronaut. I let my astigmatism and nearsightedness stop me from pursuing that dream. Perhaps, I gave up too soon. Thanks for living the dream for me. My question is I know you look down on earth a lot from space, but do you ever look out at the stars, planets, nebulas, galaxies, or other celestial objects from your perspective? What’s that like?

    I am an old lady now, and it is amazing what has occurred in my lifetime. I have to admire you gentlemen for embarking on such a marvelous adventure. I can only remember being afraid to leave my home town of 500 population, and here you guys are completely out of this world. I do have a question as I continue to watch you trek – and have noticed that there is a specific area of what I think is three orbits around. Is there any reason for choosing this location to continue around the earth. Can you orbit in any other direction except the center of the earth? Have a wonderful day, and God Bless you marvelous creatures.

    Can you imagine applications of a 3D printer being useful on the ISS ?

    Hello,
    When I look up on a clear night to the stars, I have an overwhelming feeling of how small I am in comparison to how big the universe is, but most of the time in my day to day life. I hardly ever think about how big the universe is compared to me..
    So, my first question is…
    What is your feeling about the size of the universe when you are in space? When your return to earth does your view on life on our planet change from what it was before you were in space?

    My last question for you is …
    What is the first thing you crave, miss or wish you had with you when you are on a mission in space (besides family)?

    Thank you for your time and all of the work that you do. God Speed.

    Hello!

    Congratulations on growing vegetables in space! As we have learned earlier in the show, water is a tremendously valuable resource. Do you think we will see the growing application ISS uses in advancing agriculture and lifting up humanity in places where water and food are scarce?
    Also, space gardening must be an amazing reminder of home!

    I have heard that if astronauts spend a certain amount of time in space in a non-gravity environment, that they cannot return to earth as gravity would prevent them from even being able to breath, stand, walk and that their body would not be able to function properly to allow them to remain in a gravity environment such as earth. Is this true?
