On September 21, the Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft successfully entered orbit about Mars with a goal to investigate the planet’s atmosphere and ionosphere. SESDA engineers were core to the design and fabrication of components for two of the instruments, the Neutral Gas and Ion Mass Spectrometer (NGIMS) and the magnetometer (MAG). Going forward, SESDA staff will support instrument operations and science telemetry processing as well.

SESDA Staff Expose “Jack-o’-Lantern” Sun

An image taken by NASA’s Solar Dynamics Observatory on October 8 bears an eerie resemblance to a familiar Halloween sight. “Active regions on the Sun combined to look something like a solar jack-o’-lantern’s face,” said Joe Witte of NASA’s Goddard Space Flight Center. “The active regions in this image appear brighter because those are areas that emit more light and energy,” explained Witte. He also noted that: “This image blends together two sets of extreme ultraviolet wavelengths.” The report was picked up by CNN and numerous other news outlets. More details are available in a story written by ADNET’s Karen Fox, with additional support from ADNET Senior System Administrator Aaron Lepsch of Goddard’s Scientific Visualization Studio.
