Proposed questions generated by the ASU Preparatory STEM Academy students:
1. How does your daily routine on the ISS help keep you healthy and safe in space?
2. How does living in space affect your senses – like how things smell, taste, or sound – and how do you adjust to that?
3. Why is it important for scientists to do experiments that they can’t do on Earth?
4. How do astronauts keep track of time on the ISS when you see many sunrises each day?
5. What do you think humans need to learn or practice on the ISS before we can live on Mars?
6. When you look out the window of the space station, what do you look for first?
7. If your mission was unexpectedly extended by a month, what would be the hardest part?
8. What observation or experiment in space surprised you the most, and why was it unexpected?
9. What view from space made you stop and think, “I’ll never forget this!”?
10. When you look at Earth and see city lights, then look into dark space, how does that change the way you think about our planet and your place in the universe?
11. When everything floats, how do you stay organized and make sure nothing gets lost?
12. How does it feel to move your body without gravity, and what was the hardest thing to learn at first?
13. Which space experiment do you think will make the biggest difference in everyday life on Earth, and how?
14. How do you sleep without a bed, and how does sleeping in space affect your body?
15. What special techniques help plants grow in space, and why is learning this important for future missions?
16. When you miss your family, what helps you feel connected even though you are far away?
17. Do you have a favorite constellation you can see from space, and does it look different than from Earth?
18. How are astronauts trained to handle medical emergencies in space, and how is it different than what doctors do on Earth?
19. If humans were going to live on another planet someday, which planet do you think would be the best choice, and what challenges would people need to solve first?
20. We hear the ISS may be decommissioned around 2030. Does this possible end date affect the type of research you do now, and what do you hope scientists learn before then?
