Excellent work!

Great educational videos! I am an Assistant English Teacher in a small town in Japan. I am constantly looking for simple podcasts to show to my students. Although the English in these videos is too difficult for junior high students I may still show a few. The videos are fun and easy to understand. They are also a good review of my physics class from college :) Good work NASA!


I have children who are constantly wanting to use my Ipod when we are out. I appreciate the alternative! Thank you for giving us the option to view podcasts that are not only interesting, but also educational -for all ages! If anyone has any interest at all in the world/universe in which we live, these podcasts are an excellent choice!

Great for all ages

My 5 year old loves space and will watch these over and over. While he does not understand everything, it provides information to him and me making him even more curious. more please...
