Welcome to SESDA II
Welcome to the Sciences and Exploration Data Analysis (SESDA II) home page. SESDA II is the premier space and Earth science contract at NASA’s Goddard Space Flight Center, held by ADNET Systems, Inc. ADNET, Wyle and Honeywell form TEAM ADNET.
About 300 scientists and engineers provide vital support to NASA under the SESDA II contract. Watch this site for exciting SESDA II news, events and job opportunities.

What a Long, High-Energy Trip It’s Been!
January 12, 2012
After 16 years of discovery, the mission of the Rossi X-ray Timing Explorer (RXTE) has reached the end of science operations. The spacecraft began the decommissioning process during the week beginning Monday, January 2, 2012, and science observations concluded at the end of the day on January 3, 2012. Fittingly, the final observation was of Scorpius X-1, the first X-ray source ever discovered outside the Solar System and still the most energetic known. The RXTE mission was launched on December 30, 1995 and SESDA II scientists, programmers, and mission planners have been a proud part of the support team throughout the mission’s highly productive scientific lifetime.
Superfast Networks on Display
December 28, 2011
Network researchers, including ADNET HECN staff, troubleshoot the high-bandwidth connection between Seattle and Greenbelt.
SESDA's High End Computing Network (HECN) group continues to break new ground in network speeds. The group operates out of GSFC Code 606.1, the Networks and IT Security branch, and their project was cited as one of the top exhibits at the Super Computing 2011 (SC11) convention in Seattle last November. The team demonstrated unprecedented high-speed data transfer rates using custom built RAID servers that achieved a lightning-fast 60 Gbits/sec disk-to-disk transfer rates across the nearly 3000-mile distance between Seattle and Goddard Space Flight Center, and 72 Gbits/sec locally.
The HECN group also had a successful proposal to the Department of Energy that allows them to use DOE’s Advanced Networking Initiative (ANI) 100G test bed. Their project will allow them to evaluate advanced network cards as well as next-generation servers, performance measurement tools, and applications that will support highly parallel, multi-core architectures. Their goal is to keep pushing the envelope as they approach 100 Gbit/sec transfer rates. These enormously high bandwidths will prove critical as both NASA and the commercial world move towards cloud computing.
