Coronavirus Impacts Field Work

Goddard Space Flight Center airborne campaigns are highlighted in a recent Capital Weather Gang article in The Washington Post. The article describes the novel coronavirus's impact on scientific research and field campaigns.

NASA Code61A personnel received Honor Awards in 2019

Bryan Blair (Code 61A) David Rowlands (Code 61A) received NASA Honor awards in 2019. Carey Noll received an SLR Pioneer Certificate from the International Laser Ranging Service (ILRS). David Gordon received the Peter McGregor Prize of the Astronomical Society of Australia, as part of the DiFX Collaboration.

Bryan Blair (Code 61A) received the NASA Honor Award - Exceptional Technology Achievement Medal, with the citation: "For pioneering development of waveform lidar sensor technology for land surface characterization, vegetation structure, biomass, and mapping land and sea ice change. "

David Rowlands (Code 61A) received the NASA Honor Award - Exceptional Service Medal, with the citation, "For nearly four decades of sustained exemplary performance delivering technical innovations and capabilities that have advanced numerous NASA Earth and planetary missions."

Dr. Toshimichi Otsubo, Chair of the International Laser Ranging Service (LRS), presented Carey Noll (Code 61A) with a "Pioneer Certificate" at the 2019 SLR Technical Workshop in Stuttgart, Germany (Oct. 21-24, 2019), "In recognition of her dedication, vision and creativity in supporting all aspects of the ILRS".

David Gordon (NVI @ Code 61A, NASA GSFC) received the Peter McGregor Prize of the Astronomical Society of Australia as part of the DiFX Collaboration (an international team) for contributing to the development of the DiFX software with the following Citation:
"The Distributed FX Correlator (DiFX) is a software package that contains tools necessary to turn an array of radio telescope signals into a functioning radio interferometer. The DiFX has contributed significantly to reducing the barrier to entry and play a major role in radio astronomy research internationally. The system has enabled a wide range of science, as testified by the very high number of references to the key technical papers. The open-access nature of the software has put a new tool in the hands of astronomers, with demonstrated positive results. Its scalability and adaptability has and continues to enable researchers to tailor its behaviour and pursue what would otherwise be difficult science goals."
The members of the DiFX collaboration include: Adam Deller (Leader, Swinburne University of Technology, Australia), Walter Alef (Max Planck Institute for Radio Astronomy, Bonn, Germany), James Anderson (GFZ/Potsdam, Germany), Matthias Bark (NRAO, USA), Matthew Bailes (Swinburne University of Technology, Australia), Walter Brisken (NRAO, USA). Roger Cappallo (MIT Haystack Observatory, USA), Geoff Crew (MIT Haystack Observatory, USA), Richard Dodson (The University of Western Australia), David Gordon (NVI @ Code 61A, NASA GSFC), Zheng Meyer-Zhao (Netherlands Institute for Radio Astronomy, The Netherlands), John Morgan (Curtin University, Australia), Chris Phillips (CSIRO Australia), Cormac Reynolds (CSIRO Australia), Jon Romney (NRAO, USA), Helge Rottman (Max Planck Institute for Radio Astronomy, Bonn, Germany), John Spitzak (US Naval Observatory), Matteo Stagni (National Institute for Astrophysics, Italy), Steven Tingay (Curtin University, Australia), Jan Wagner (Max Planck Institute for Radio Astronomy, Bonn, Germany), Mark Wainright (NRAO, USA) Randall Wayth (Curtin University, Australia).

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.
