Welcome to SESDA

  • SESDA Team Supports New Immersive Scientific Visualization System

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.

SESDA Engineers Help Deliver an Early Xmas Present

December 27, 2018


On 7 December 2018, the VISIONS-2 suborbital rocket pair successfully launched from Svalbard, Norway. The two rockets launched two minutes apart with sophisticated instrumentation designed to study ion outflow in the geomagnetic cusp. SESDA engineers in the Heliophysics Science Division played multifaceted roles in ensuring the success of the mission that ranged from designing and building key electrical and mechanical instrument components, performing critical integration and testing, and providing onsite launch support. Congratulations on a job well done!

Voyager 2 May Soon Be Joining Its Twin in Interstellar Space

October 29, 2018


In 2012, Voyager 1, one of a pair of deep-space probes launched in 1977, crossed into a part of space no other spacecraft had ever seen: the interstellar medium. At over 11 billion miles from the Sun, crucial changes were detected in the data Voyager 1 was sending back to Earth – key observations to show that Voyager 1 was entering interstellar space. The planets in the solar system are surrounded by an outpouring of material from the Sun, called the solar wind, which creates a giant bubble called the heliosphere. Eventually, the solar wind peters out, held back by the wind coming from other stars – and this is the boundary that Voyager 1 crossed. High energy particles are known to originate outside our heliosphere and don’t easily penetrate. Observation of an increase in flux of such particles is a strong indication that the boundary has been crossed. Data from the Cosmic Ray Subsystem (CRS) instrument on the spacecraft showed this increase at Voyager 1 and the CRS on Voyager 2 is now seeing the same effect. The image shown an artist’s drawing of the respective locations of the spacecraft. A SESDA staff member is responsible for processing the CRS data and assisting with data analysis.
