Welcome to SESDA

  • SESDA Supports Development of NICER Repair Tools

ADNET Systems Inc. has been awarded the Space and Earth Science Data Analysis (SESDA-V) contract by the National Aeronautics and Space Administration (NASA) to support the Goddard Space Flight Center (GSFC) in Greenbelt, Maryland. SESDA-V is a five-year cost-plus fixed-fee contract with a total potential value of approximately $342 million.

Under SESDA-V, ADNET will provide a broad range of services to support Space and Earth 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 fourth consecutive time ADNET Systems has been selected for this prestigious contract. More than 300 scientists, engineers, IT professionals, and education outreach specialists support the SESDA contract across a broad range of science disciplines, including solar and space plasma physics, astrophysics and astronomy, planetary studies, 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 fourth time.” said Ashok Jha, President and CEO of ADNET.

SESDA Supports Server Migration

 June 13, 2025

GISS server racks

Several SESDA System Administrators, Network & Security Engineers and Facility Specialists supported server migrations from New York to Greenbelt (including the physical move of the servers, installations of racks & servers in a dedicated GSFC server room, configuring network devices, arranging and setting up power and cooling, etc.) after NASA cancelled the GISS facility lease with Columbia University on short notice. The whole effort took less than 3 weeks and the GISS website was down for less than an hour, thanks to careful planning of staff in both NY and MD and outstanding efforts from all involved. We received congratulations and acknowledgements from the Director of GSFC, Makenzie Lystrup.

The pictures show the GSFC location and server installation as of June 5, 2025 – more equipment arrived that day to be installed.

SESDA Supports Development of NICER Repair Tools

 August 6, 2024

NICER-repair-caddy: The NICER caddy is an aluminum box containing two of the mission’s spare sunshades, which are attached to the bottom. Inside the sunshades, 12 patches are locked into place. Astronauts will take the complete caddy assembly with them during a future spacewalk to address damage to NICER’s thermal shields.

The extremely successful GSFC project, NICER (Neutron star Interior Composition Explorer), was launched in June of 2017. In 2023 it was damaged by debris and its operating time became limited to nighttime observations only. SESDA personnel contributed to the rapid development and fabrication of the repair parts, and a repair plan was put in place. After a successful Florida launch on August 4, 2024, the capsule carrying the repair kit was captured by the robotic arm of the space station. An astronaut will perform a space walk later this year to install the repair components. NICER will be the first X-ray telescope in orbit to be serviced by astronauts. The repairs should restore NICER to full time operation studying the X-ray sky.
