Ask NASA Astronauts Your Question With #HelloFromEarth

Want to chat with the astronauts on the International Space Station? National Geographic Channel is taking viewers into orbit with Live From Space, a live event broadcast from the ISS.

As part of the broadcast, NASA astronauts Rick Mastracchio and Koichi Wakata located on the ISS will answer your questions about life in space.

Want to make your voice heard? We’re using Instagram to collect questions and waves for the astronauts. Here’s how to submit:

    Hey, can you guys see the Black Knight Alien Satellite from where you are? Any other UFO’s flying around up there? We know they exist, but NASA likes to keep the general public in the dark.

    I was wondering if we could find the black hole and send out a drone and through it will we be able to get information on the location or will the black hole destroy the drone with its mass?

    1. Is space debris a real problem as it is shown in the film gravity?
    2. How do you take care of yourself from direct sun rays…I have heard that you are not supposed to see the sun directly.
    3. IF you get bored, you should be allowed to go around in a space transportation of yours 🙂 do you agree?
    4. We all are sexual beings. How this affects astronauts who are put to stay for longer duration?
    5. Lastly I have a heartbeat in Dubai. Can you please snap Dubai from space for me:)

    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!

    Hey guys, I’ve always wondered what re-entry into Earth’s atmosphere is like? I bet it’s pretty intense.

    It would be cool if you could get some footage inside the capsule on the way down. 🙂

    Some questions to the Astronauts that 1) when they travells in the space with sudden change in gravity what happened to their condition, whether their old disease condition got relief? what Are the disease condition they did suffered while in space?

    We know nasal have found over 60 new planets in another solar system but to get there would it be possible to create a gravitational pull by using the satellites around our system to either pull them to us or us the them or would that vaporise us/them
