Destination: Space

Will humans ever be able to live on other planets? Former astronaut Dr. Dave Williams has the answers for you. Even though Earth is a pretty good place to live, there are other places in our galaxy that many be future destinations. Could it be Mercury, where the temperatures are 10 times hotter than on Earth? Or how about Neptune, where winters last 40 years? Join Dr. Dave on some space travels to other planets in our galaxy to explore which planet holds the most promise for our next space exploration.
