Question
I was wondering whether you think it is likely that people will eventually move to space to live there perminantly. If so, do you think it is more probable that they will move onto other planets or into 'space stations' which orbit the planet.
Additionally, I was wondering, on rockets, is gravity simulated or do astronauts just live in a gravity free zone? Is it possible for plants to grow in a gravity free environment?
Cathy:
I would hope that in the future people will be living on other places in the Universe.
Well, there is NO SUCH THING as no gravity. There is gravity in every square inch of the universe. What we sometime call "Zero G" or "Zero Gravity" actually means very little gravity.
On the space station or shuttle, the Astronauts are in "Zero G", however, by "spinning" a space station, you can simulate more gravity.
I am not sure about the plant growth. I THINK that astronauts have grown plants in zero G.

| Comment | Question regarded the purpose of an antique scientific instrument. Steve researched the question and came up with a photo of a very similar instrument made in 1895. Great work! | ||

Expertise
As a space science educator in a planetarium, my work centers around teaching people about the night sky and the solar system. I have a strong background in those areas, plus the history of NASA and spaceflight, and meteorology.
Experience
Experience in the area. I have been an amateur astronomer for 47 years, and have been teachng space science in planetariums for 34 years. For 15 years I was a radio and television meteorologist, and for the past 20 years I have been a space science writer for two newspapers in New York State. I am a member of the Middle Atlantic Planetarium Society and the International Planetarium Society. I have had a number of articles published in several astronomy journals, including "The Constellation" and the "Planetarian". Education/Credentials. I hold a B. S. from Wagner College and an M. S. from State University of New York at Oswego. Awards and Honors. I have been awarded the "Fellows" award from the International Planetarium Society for more than 20 years of continuous service in the planetarium field.
