Space exploration as we know it is mysterious and magical.
But did you know that astronauts aboard the international space station conduct medical experiments year.
Studies in the past have looked at blood pressure pathologies, airway monitoring and telomere length in astronauts.
Astronauts aboard the iSS are even conducting ecological experiments and growing LETTUCE.
We hope Bob and Doug bring back some luscious microgravity grown lettuce.
