Space Geodesy Project Hosts Tour

The Space Geodesy Project (SGP) hosted NASA Acting Administrator Steve Jurczyk, Associate Administrator for Science Mission Directorate Thomas Zurbuchen, and the NASA Goddard Executive Council for a tour of the geodetic stations at the Goddard Geophysical and Astronomical Observatory (GGAO). Stephen Merkowitz (61A), Jan McGarry (61A), Evan Hoffman (61A), Mark Clampin (600), Jim Irons (610), and several other members of SGP supported the tour. The clear sky that evening provided excellent viewing of the laser from the MOBLAS-7 Satellite Laser Ranging Station as seen in this tweet by Dr. Zurbuchen.

NCSA Science Story Features SAA Work

National Center for Super Computing Applications (NCSA) featured a science story on geomagnetic South Atlantic Anomaly (SAA) prediction results from 61A's Geomagnetic Group.

Kuang, Sabaka, and Tangborn Highlight the SAA

Weijia Kuang (61A), Terence J. Sabaka (61A) and Andrew Tangborn (UMBC) contributed texts and figures of South Atlantic Anomaly (SAA) to the EOS Science News article entitled “The Herky-Jerky Weirdness of Earth’s Magnetic Field” by J. Duncombe.

The laboratory performs broad research, in the areas of Earth time variable and static geopotential and geomagnetic fields, Earth orientation, surface deformation, characterization and change, tides, land ice mass evolution, global and regional sea level, and airborne and spaceborne laser altimetry. The laboratory also supports many NASA missions in fundamental and core capabilities including satellite radar and laser altimetry precise positioning, pointing, ranging, timing, geolocation and calibration and validation. The laboratory is a leader in the design, development, implementation and application of airborne and spaceborne geodetic laser altimeter technology and instruments including NASA’s Land, Vegetation, and Ice Sensor (LVIS) and the Global Ecosystem Dynamics Investigation Lidar (GEDI). The laboratory is the home of the Space Geodesy Project which encompasses the management, development, operation and maintenance of NASA’s Space Geodetic Network that is comprised of the four major space geodetic observing systems: Very Long Baseline Interferometry (VLBI), Satellite Laser Ranging (SLR), Global Navigation Satellite System (GNSS), and the Doppler Orbitography and Radio-positioning by integrated Satellite (DORIS) system. It is also home to the Crustal Dynamics Data Information System dedicated to the archive and distribution of space geodesy related data sets; as well as the home to GEODYN, NASA’s state-of-the-art geodetic parameter estimation and precision orbit determination system.
