The Crustal Dynamics Data Information System (CDDIS) supports data archiving and distribution activities for the space geodesy and geodynamics community. The poster provided background information about the system and its user communities, archive contents and updates, enhancements for data discovery, new system architecture, and future plans.
NASA’s Space Geodesy Project (SGP) is developing a prototype core site for a next generation Space Geodetic Network (SGN). The status of the prototype next generation space geodetic core site, results from the analysis of data from the established geodetic stations, and results from the ongoing network design studies were presented.

Evolution of Timescales from Astronomy to Physical Metrology
Seasons, the phases of the Moon and the changing aspect of the Sun in the sky have long provided us with opportune means to mark the changes in our environment. Devices of various degrees of sophistication have been developed throughout history to make the necessary observations, and along with those devices, create timescales. The evolution of devices, algorithms and the underlying philosophical concepts of time itself continues today, and is likely to continue into the future.

The Crustal Dynamics Data Information System (CDDIS) has supported the archive and distribution of geodetic data products acquired by NASA as well as national and international programs since 1982. This talk will discuss the CDDIS, including background information about the system and its user communities, archive contents, and future plans. Presented by Carey Noll
Scientists specializing in Titan research presented the newest findings from the Cassini spacecraft. The latest images and results were highlighted during four 10-minute presentations geared toward members of the public and students high-school age and older. Afterward, the speakers answered questions from the audience. Following the presentations, visitors were treated to movies on the mesmerizing Science on a Sphere and gazed at the planets through telescopes provided by the Goddard Astronomy Club.
Conor Nixon from code 693 moderated the panel.
