The Unified Astronomy Thesaurus (UAT) is an open, interoperable and community-supported thesaurus which unifies the existing divergent and isolated Astronomy & Astrophysics vocabularies into a single high-quality, freely-available open thesaurus formalizing astronomical concepts and their inter-relationships. The UAT builds upon the existing IAU Thesaurus with major contributions from the astro...

NASA's Mars Geodesy/Cartography Working Group (MGCWG), established in 1998 and chaired since 2000 by one of us (TCD), consists of leading researchers in planetary geodesy and cartography at such diverse institutions as JPL, NASA Ames and Goddard Centers, Purdue and Ohio State Universities, Malin Space Science Ssystems, the German Center for Aerospace Research DLR, and the US Geological Survey, ...

The method of constructing of rotation curve for our galactic disk is developed. Simple physical model shows that the velocity of the Sun around the center of the Galaxy must be less than currently accepted IAU value 220 km/s. Independently obtained result for neutral hydrogen (λ = 21.1 cm) confirms the previous statement. The values of the Sun’s velocity is about 110 km/s. As a consequence, th...

Co-I Braun was on extended family leave for much of this quarter, due to the birth of his daughter on May 10. Other members spent considerable time preparing for, and attending, a number of summer workshops and conferences. These included the conference on “MHD Waves and oscillations in solar magnetic structures” in Palma de Mallorca, Spain (May 29 Jun 1), the SPD meeting in Durham, New Hampshi...
