Team Lead for Cassini Ion and Neutral Mass Spectrometer, Southwest Research institute, Hunter Waite, points to a model of NASA's Cassini spacecraft at a news conference at Jet Propulsion Laboratory (JPL) as the spacecraft nears the end of its 20-year mission by crashing into Saturn, in Pasadena, California, Sept. 13, 2017. It took Cassini seven years to reach Saturn after its 1997 launch where it has been exploring the ringed planet and its many moons for the past 13 years. It will continue to transmit data and never before seen photos to Earth for as long as possible before breaking up and crashing. (Photo/Agencies)
