NASA Aerospace Institute - Day 4: Today's workshop focused on the light spectrum and its relationship to satellite imaging and learning about distant stars. One experiment entailed utilizing spectroscopes, which is a method used to tell what gasses lie between us and a distant star. By looking at the color spectrum scientists can determine what the atmosphere is made of in a distant star! We also learned about NASA spin offs that have been used by society to help make our lives easier, and the list goes on and on. Some examples include imaging techniques for health and medicine, an all-terrain robot that saves lives, improving upon solar energy, a pesticide-free device to get rid of mosquitoes, germicides, satellite technology, enhancing high-speed data collection and much, MUCH more! For the day's finale we watched a realistic, 3D IMAX movie about future moon explorations as a taste of what's to come.

Today's factoid: Despite the high cost of space exploration endeavours, NASA only receives 7/10 of 1% of the US budget. That's less than a penny per tax dollar, and no price can be put on the tremendous benefits that mankind receives from NASA's ongoing discoveries in the fields of science, technology, engineering and mathematics!
