  • 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.

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.

SESDA Scientist Spots a Rare Rectangular Iceberg

October 25, 2018


NASA’s longest-running aerial survey of polar ice flew over the northern Antarctic Peninsula on Oct. 16, 2018. During the survey, designed to assess changes in the ice height of several glaciers draining into the Larsen A, B and C embayments, IceBridge senior support scientist Jeremy Harbeck spotted a very sharp-angled, tabular iceberg floating among sea ice just off of the Larsen C ice shelf. A photo of the iceberg (below) was widely shared after it was posted on social media. “I thought it was pretty interesting; I often see icebergs with relatively straight edges, but I’ve not really seen one before with two corners at such right angles like this one had,” Harbeck said. The rectangular iceberg appeared to be freshly calved from Larsen C, which in July 2017 released the massive A68 iceberg, a chunk of ice about the size of the state of Delaware. The flight originated from Punta Arenas, Chile, as part of a five-week-long IceBridge deployment, which began Oct. 10 and is scheduled to conclude Nov. 18.
