NASA has defined a set of Space and Earth science questions and a new website to address them. What “big questions” would you like to know more about?
Planets Questions, such as “How did the sun’s family of planets and minor bodies originate?”
Astrophysics Questions, such as “What are the origin, evolution and fate of the Universe?”
Earth Questions, such as “How does the earth system respond to natural and human-induced changes?” and
Heliophysics Questions, such as “How does solar variability affect human society, technological systems and the habitability of planets?”
The site offers details on the many NASA missions that have gathered data relevant to each of the “big questions.” It’s a nice looking site, with some pages directed specifically to students and teachers.
