  • SESDA Supports Successful Rocket Launch From Norway

ADNET Systems Inc. has been awarded the Space and Earth Science Data Analysis (SESDA-IV) contract by the National Aeronautics and Space Administration (NASA) to support the Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. SESDA-IV is a five-year cost-plus fixed-fee contract with a total potential value of approximately $250 million.

Under SESDA-IV, ADNET will provide a broad range of services to support Earth and Space science research and development, data operations, as well as activities in information system technologies, engineering, and science communication, education and public outreach that enable the Sciences and Exploration Directorate to successfully carry out its science missions at the Goddard Space Flight Center (GSFC).

SESDA is the premier Space and Earth science contract at GSFC and this award represents the third straight time ADNET Systems has been selected for this prestigious contract. Over 300 scientists, engineers, and education outreach specialists support the SESDA contract through a broad range of science disciplines, including solar and space plasma physics, astrophysics and astronomy, planetary studies, atmospheric science and climatology, oceanography, land processes, geodynamics, and solid earth geographics. “All of us at ADNET are pleased and excited to continue our partnership with NASA and we are thrilled to be selected as the SESDA contractor for the third time.” said Ashok Jha, President and CEO of ADNET.

ADNET Scientists Analyze Micronesian Phytoplankton

Cover of Earth journal issue featuring Phytoplankton Bloom analysis

ADNET scientists Jim Acker and Alexis Hunzinger recently authored a study that was featured on the cover of the journal Earth. In October 2013, ocean color remote sensing data acquired by the Moderate-resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite showed a unique elevated phytoplankton chlorophyll feature extending eastward from Chuuk Lagoon in the Federated States of Micronesia. Analysis of Modern-Era Retrospective analysis for Research and Applications (MERRA-2) windspeed and wind direction data, enabled with the NASA Giovanni system, indicated that alternating high and low windspeed periods, combined with seasonal wind directions and the physiography of the atoll, likely created ideal surface ocean conditions for a phytoplankton bloom in and adjacent to the lagoon. Light availability for photosynthesis may also have contributed to bloom timing and development.
