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.

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. […]
