Army Communication-Electronics Command and the Fort Monmouth community was instrumental in the success of Project Diana, an effort by scientists at Camp Evans to pierce the earths outer atmosphere with high frequency radio signals (radar) that ultimately helped launch America into the space age.
Mira is approximately 500 times the diameter of the Sun and so cool (for a star) that it has water vapor in its outer atmosphere.
Since the core of the sun is where the star generates its heat, the fact that the outer atmosphere - farther from the core than the photosphere - is hotter than the surface requires an explanation.
Using its satellite broadband network coupled with its airborne satcom terminals mounted onto two of NASA's WB-57 high altitude research aircraft, ViaSat enabled a successful HD video live stream of high-resolution images of the Sun's corona, its outer atmosphere, during totality of Monday's total solar eclipse, and provided two-way communication between the planes and controllers on the ground.
One telescope will observe green emissions from ionised iron atoms in the sun's outer atmosphere.
