Hello From Above Our Magnificent Planet Earth.

Life Science Research Can Be Done On Multiple Platforms. Since We Have A Very Small Number Of People Flying Into Space, The More People You Have, The Better.

The Microgravity Or The Very, Very Low Amount Of Gravity That We Have Up In Space Forces Some Changes In Different Processes. It Forces Changes In Us As Human Beings.

I Can't Think Of Anything Specific Growing Up That Pointed Me Toward Nasa At All. I Was Interested In The Moon Landings Just About The Same As Everyone Else Of My Generation. But I Never Really Thought About Being An Astronaut Or Working In Space Myself.

Gravity Is One Variable In A Lot Of Scientific Processes. If You Can Remove Gravity Or Minimize Its Effect, Then You Can Understand The Other Processes That Are Going On.

Some Things Are Only Capable Of Being Done In Space. Examples Of That Are Looking At Our Earth From That Far Away, And Understanding The Entire Processes Of Storms And Weather Patterns, And Oceans, And Coastlines.
