Long shadows are cast by the recently completed Deep Space Station 23 at the Deep Space Network’s Goldstone complex near Barstow, California, in August 2026. A 34-meter (114-foot) multifrequency beam-waveguide antenna, DSS-23 will boost the DSN’s capacity and enhance NASA’s deep space communications capabilities for decades to come. NASA leadership and personnel as well as

This map of Addis Ababa, the capital of Ethiopia, shows the locations of 10 air sensors that NASA’s Multi-Angle Imager for Aerosols (MAIA) mission is using to provide one of the most detailed looks ever at the city’s air pollution. Over the course of three years, these sensors measured particulate matter that is 2.5 micrometers or less in
This roof-mounted air sensor in Addis Ababa, the capital of Ethiopia, is one of 10 used by NASA’s Multi-Angle Imager for Aerosols (MAIA) to study the city’s air quality. MAIA’s air sensors provide a detailed look at particulate matter that is 2.5 micrometers or less in diameter, also known as PM2.5, one of the world’s deadliest forms of
SkyFall ground-penetrating radar engineer Maya Román connects a coaxial cable to a test antenna in the Environmental Test Lab’s electromagnetic interference testing chamber at NASA’s Jet Propulsion Laboratory in Southern California. The antenna was pointed up during test to minimize reflections and interferences with the antenna pattern during the measurement. Equipped with four instruments each, the three
This artist’s concept depicts NASA’s three SkyFall Mars helicopters collecting data while flying over the surface of the Red Planet. The green frequency waves emanating from the helicopters’ large antennas depict collection of subsurface radar data. The red beams depict collect near-infrared imagery data from regolith (crushed rock and dust) and other surface features. Equipped
