Heliophysicists Blaze a CubeSat Trail

September 29, 2014

SESDA 3 engineers are supporting NASA/GSFC in developing micro-electronics for a new-generation miniaturized mass spectrometer payload to be launched on a CubeSat. The spectrometer will measure the composition and density of ions and neutral elements in Earth’s lower exosphere and upper ionosphere. The objective is to fly many of these instruments to gather simultaneous multipoint measurements, which is only possible with CubeSat platforms.

Big solar storm hitting Earth (so CNN says)

September, 2014 coronal mass ejection

SESDA 3 staff braced for the possible next “big” one – a significant X-class flare erupted on September 10, 2014 and produced two Coronal Mass Ejections (CME’s) directed towards Earth. By combining real-time imagery from three spacecraft – SOHO, STEREO, and SDO, staff helped provide accurate space weather forecasts of the speed and intensity of the powerful storms as they impacted Earth’s magnetosphere. Fortunately, the storms did not knock out the power grid and instead generated beautiful aurora at high latitudes.
