Welcome to SESDA

  • The Total Solar Eclipse of 2017

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.

The Total Solar Eclipse of 2017

August 28, 2017


Over the last three years, SESDA staff comprising the NASA Heliophysics Education Consortium (HEC) has been planning and designing the largest education event that NASA has ever attempted – the August 21st, 2017 Total Solar Eclipse. Staff scientists, computer system professionals, web developers, education technology specialists, and educators successfully brought the event to fruition in Carbondale, IL for a weekend of eclipse programs and celebrations at Southern Illinois University culminating with a 4 hour NASA EDGE webcast. SESDA staff coordinated the efforts of over 100 NASA and external groups, 300 Subject Matter Experts, and 94 official NASA eclipse sites around the country. Preliminary results indicate over five billion web hits and 200 TB of downloaded data..

Early Movies of Cassini’s First Dive

Still from Cassini’s ‘Porthole’ Movie of Saturn


In preparation for its grand finale plunge into Saturn in mid-September, 2017, the Cassini spacecraft has begun a series of orbits which bring it to within 5,000 miles of the planet’s cloud tops. Its new trajectory allows for the collection of exceptionally high resolution science data that hasn’t been possible since Cassini was first inserted into orbit in 2004. In particular, several movies taken April 26 have been created by the Cassini imaging team of the first, low altitude dive showing the north pole’s hexagonal-shaped jet stream and the spacecraft’s path along the planet’s surface. Future passes will include science and engineering data from the Composite Infrared Spectrometer (CIRS) using instrument command sequences created by Team ADNET/SESDA instrument operators and programmers.
