Welcome to NSSDC's General Public Page! T HIS PAGE is intended to guide members of the general public to NASA/NSSDC data and services most likely to be of interest to the non-researcher/scientist segment of the internet community. Our Role T HE National Aeronautics Space Administration (NASA) carries out its functions through several offices. NASA's Office of Space Sciences sponsors the National Space Science Data Center (NSSDC). NSSDC is primarily responsible for the archiving of space science data from past, present, and future NASA missions. We serve the science community and the general public in areas related to the space sciences (astrophysics and astronomy, solar physics, space plasma physics, lunar and planetary science). N SSDC is not intended as, nor is it, an encyclopedic source of information about NASA, its space activities, or space science in general. We provide data, and such information as we happen to have. There are many alternative sources of information about NASA, its activities, and space; several of these are identified below. Access to NSSDC's online WWW files, data, and information is free; nominal charges are made for dissemination of data on media, as, for instance, NSSDC's Planetary Images CD-ROM.

Credit: Lawrence Berkeley National Laboratory Catching neutrinos from the Sun. The Sudbury Neutrino Observatory (SNO) is hardly your average physics experiment: buried in a 2000 meter deep mine in Ontario and filled with 1000 tons of heavy water, its purpose is to catch neutrinos, spritely particles which form in the center of the Sun and usually fly through the Earth without being captured. Recent results from this experiment have solved a long-standing discrepancy; we now know that the number of neutrinos observed from the Sun is equal to the predictions of theoretical nuclear physics and that neutrinos can oscillate between three different "flavors" during the course of their trip. General Physics Links Questions Although our website is about astronomy, we receive many questions that are related, in whole or in part, to the science of physics. This isn't a surprise, because astronomy and physics are intimately tied together. Physics is the study of the laws that govern the universe, and to the best of our knowledge, those laws are the same here and now as they were long ago and far away. In order to explain what we see in the night sky, therefore, we appeal to theories originally developed to explain physical phenomena on the Earth. In addition, the extreme environments encountered in astrophysical situations provide a "laboratory" to test these theories under conditions that we could never hope to recreate ourselves.
