official news from : https://bit.ly/2QkyIbY In our modern wireless world, almost all radio frequency (RF) spectrum bands are shared among multiple users. In some domains, similar users technically coordinate to avoid interference. The spectrum management team, part of NASA’s SCaN (Space Communications and Navigation) Program, represents the collaborative efforts across U.S. agencies and the internationalContinue reading “NASA Collaborates to Enable Spectrum-Dependent Science, Exploration, and Innovation   “

official news from : https://bit.ly/2QkyIbY Spectrum is a shared resource. Since the discovery of radio waves and the invention of the telegraph, humanity has exponentially increased its use of the radio frequency (RF) spectrum.  Consider how many wireless devices are around you right now.  You’re probably reading this on a smartphone or laptop connected toContinue reading “Management and Regulation Ensure Effective Spectrum Sharing “

official news from : https://bit.ly/2QkyIbY As associate administrator for NASA’s Space Operations Mission Directorate Ken Bowersox puts it, “nothing happens without communications.”   And effective communications require the use of radio waves.   None of NASA’s exciting science and engineering endeavors would be possible without the use of radio waves to send data, communications, and commands betweenContinue reading “NASA’s Use of the Radio Frequency Spectrum”

official news from : https://bit.ly/2QkyIbY When a planet’s orbit brings it between Earth and a distant star, it’s more than just a cosmic game of hide and seek. It’s an opportunity for NASA to improve its understanding of that planet’s atmosphere and rings. Planetary scientists call it a stellar occultation and that’s exactly what happenedContinue reading “Planetary Alignment Provides NASA Rare Opportunity to Study Uranus”
