Welcome to SESDA

  • SESDA Supports Mars Landing

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 Supports Another Successful Sounding Rocket Launch

August 30, 2021

Congratulations to the NASA GSFC and Wallops Flight Facility (WFF) teams on successful launches of two Black Brant suborbital sounding rockets on July 7 and 11, 2021. The twin rockets (named Dynamo-2) deployed identical latest technology payloads designed to measure DC electric fields, plasma density, currents, neutral winds, neutral density and temperature, and ion mass distributions. SESDA hardware and software engineers played vital roles in supporting the mechanical design, fabrication, assembly, integration and test (I&T) of the onboard instruments, and developing a ground-based magnetometer to monitor ionospheric dynamo region conditions.

Congratulations to the NASA GSFC and Wallops Flight Facility (WFF) teams on the successful launch of a Black Brant XII suborbital sounding rocket at 8:44 p.m. EDT on May 16, 2021. The rocket was launched from WFF and carried the KiNETic eXperiment (KiNet-X) which aims to study how energy and momentum are transported between different regions of space that are magnetically connected. SESDA hardware and software engineers played critical roles in supporting the mechanical design, fabrication, assembly, integration and test (I&T) of the onboard instruments, and developing decommutation software to read and decode the instrument telemetry stream.
