NASA Collaborates to Enable Spectrum-Dependent Science, Exploration, and Innovation   

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 international community to protect and enable […]

Management and Regulation Ensure Effective Spectrum Sharing 

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 to the internet through Wi-Fi or […]

NASA’s Use of the Radio Frequency Spectrum

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 between researchers or flight controllers and […]

Eye on Infinity: NASA Celebrates Hubble’s 35th Year in Orbit

In celebration of the Hubble Space Telescope’s 35 years in Earth orbit, NASA is releasing an assortment of compelling images recently taken by Hubble, stretching from the planet Mars to star-forming regions, and a neighboring galaxy. After more than three decades of perusing the universe, Hubble remains a household name — the most well-recognized and […]

NASA Stennis Continues Prep for Future Artemis Testing

Crews at NASA’s Stennis Space Center recently completed activation of interstage gas systems needed for testing a new SLS (Space Launch System) rocket stage to fly on future Artemis missions to the Moon and beyond. The activation marks a milestone in preparation for future Green Run testing of NASA’s exploration upper stage (EUS) in the […]

Nine Finalists Advance in NASA’s Power to Explore Challenge

NASA has named nine finalists out of the 45 semifinalist student essays in the Power to Explore Challenge, a national writing competition for K-12 students featuring the enabling power of radioisotopes. Contestants were challenged to explore how NASA has powered some of its most famous science missions, and to dream up how their personal “superpowers” […]

NASA Wins Six Webby Awards, Six Webby People’s Voice Awards

NASA was recognized today by the 29th Annual Webby Awards with six Webby Awards and six Webby People’s Voice Awards, the latter of which are awarded by the voting public. The Webbys honors excellence in eight major media types: websites and mobile sites; video and film; advertising, media and public relations; apps and software; social; podcasts; artificial intelligence, […]

Planetary Alignment Provides NASA Rare Opportunity to Study Uranus

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 happened with Uranus on April 7. […]
