grouchyy304 karma

From my daughter, 4th Grader from Walnut, CA....

Hi I'm Melanie, and I participate in First Lego League. We are learning about space. Our theme is "Into Orbit". Humans are trying to get to Mars. If they get to Mars, will they get Mars germs? Will humans get sick from Mars germs? If so, they can't go to a doctor so how will they get better? How are astronauts protected from getting germs in space? Thank you!
