The violet and blue emitters, having a high S/P ratio (see also Table 3), show a mesopic luminance that is considerably higher than their photopic counterpart, while the red-emitting phosphor, with S/P = 0.37, performs considerably worse in the mesopic region.
The key to this technical advance is a high gain antenna that will be integrated into a commercially available 3U CubeSat solar array with minimal modification of the existing solar panel design. ISARA will fly a nominal 5 month SFV mission that demonstrates the 100 Mbps data rate and elevates the antenna technology from TRL 5 to TRL 7.
On December 6, 2016, a high-energy particle called an electron antineutrino hurtled to Earth from outer space at close to the speed of light carrying 6.3 petaelectronvolts (PeV) of energy. Deep inside the ice sheet at the South Pole, it smashed into an electron and produced a particle that quickly decayed into a shower of secondary particles.
