NASA Orbiter Spots Curiosity Rover Making Tracks to Next Science Stop

The image marks what may be the first time one of the agency’s Mars orbiters has captured the rover driving. NASA’s Curiosity Mars rover has never been camera shy, having been seen in selfies and images taken from space. But on Feb. 28 — the 4,466th Martian day, or sol, of the mission — Curiosity […]

NASA’s Lucy Spacecraft Images Asteroid Donaldjohanson

NASA’s Lucy spacecraft took this image of the main belt asteroid Donaldjohanson during its flyby on April 20, 2025, showing the elongated contact binary (an object formed when two smaller bodies collide). This was Lucy’s second flyby in the spacecraft’s 12-year mission. Launched on Oct. 16, 2021, Lucy is the first space mission sent to […]

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.

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 comma
