This Week @ NASA: We’re exploring #Eclipse2017, which occurs on Aug. 21. Scientists will use the event to learn more about the universe. Eclipses, and similar events, help astronomers learn more about an object’s atmosphere. Also, SpaceX launches science & supplies to Space Station, new Communications satellite launches & Cassini begins final orbits around Saturn! Watch: http://go.nasa.gov/2fUlTT9
