NASA’s SkyFall Helicopters at Work (Artist’s Concept)
NASA’s SkyFall Helicopters at Work (Artist’s Concept)

Description 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. […]

Antenna Testing for NASA’s SkyFall Mission
Antenna Testing for NASA’s SkyFall Mission

Description 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 […]

NASA’s Perseverance Captures Phobos and Earth
NASA’s Perseverance Captures Phobos and Earth

Description This composite of seven images from the Mastcam-Z instrument aboard NASA’s Perseverance Mars rover shows Earth, visible as a small bright dot moving from upper left to lower right, passing behind the Martian moon Phobos on July 2, 2026, 1,907th Martian day, or sol, of the mission. The black background is the result of […]

NASA’s Curiosity Views a Sand-Capped Butte
NASA’s Curiosity Views a Sand-Capped Butte

Description NASA’s Curiosity Mars rover captured this sand-capped butte, nicknamed “Miraflores,” estimated to be about 20 feet (6 meters) tall, with its Mast Camera, or Mastcam, on June 11, 2026, the 4,923rd Martian day, or sol, of the mission. The butte was left behind as surrounding rock eroded away over time, deepening the broad valley […]

NASA’s Curiosity Discovers a Field of Martian Polygons
NASA’s Curiosity Discovers a Field of Martian Polygons

Description NASA’s Curiosity Mars rover captured this 360-degree view of an expanse of terrain covered in surface features called polygons on June 19 and 20, 2026, the 4,930th and 4,931st Martian days, or sols, of the mission. The rover has found polygons several times in the past, but never so many in one place. Across […]

Mapping Io’s Hidden Heat With NASA’s Juno
Mapping Io’s Hidden Heat With NASA’s Juno

Description This graphic illustrates the areas of Jupiter’s moon Io sampled by the Microwave Radiometer (MWR) instrument aboard NASA’s Juno spacecraft during two close flybys. The black overlapping lines show the instrument’s footprints during Perijove 57 on Dec. 30, 2023, when the spacecraft primarily mapped the northern hemisphere. The blue lines represent Perijove 58 on […]

NASA’s Juno Peers Beneath Io’s Surface
NASA’s Juno Peers Beneath Io’s Surface

Description This map represents data captured by the Microwave Radiometer (MWR) aboard NASA’s Juno spacecraft, indicating heat rising from just beneath the surface of Jupiter’s moon Io. While infrared instruments measure the temperature of the moon’s surface, the lowest frequency microwave channels (0.6 and 1.25 gigahertz) on the MWR can penetrate between about 6 and […]

NISAR’s L-Band Radar Reveals ‘Hummingbird’ in Antarctica
NISAR’s L-Band Radar Reveals ‘Hummingbird’ in Antarctica

Description Data from the Earth-orbiting U.S.-India NISAR (NASA-ISRO Synthetic Aperture Radar) satellite’s L-band radar was used to produce an image of Nunatak Zaterjavshijsja — a mountaintop in East Antarctica — poking out amid a stream of ice flowing northeast to the ocean. The obstruction causes stresses in the ice, heavily fracturing the surrounding surfaces with […]

NASA’s Psyche Mission Images Details of Martian Surface During Flyby
NASA’s Psyche Mission Images Details of Martian Surface During Flyby

Description Captured by the multispectral imager instrument on NASA’s Psyche mission, this is an enhanced-color mosaic created from four individual images acquired on May 15, 2026, during the spacecraft’s flyby of Mars.  Psyche was traveling from right to left (northeast to southwest on Mars) during the six minutes that it took to acquire the images for […]

Curiosity Finds Evidence of an Ancient Sandstorm
Curiosity Finds Evidence of an Ancient Sandstorm

Description Billions of years ago, an hours-long Martian sandstorm blew so intensely that sand ripples began to climb upon one another as they moved across the surface. These layers of sediment eventually hardened into the multilayered rocks seen in this image, which was taken by NASA’s Curiosity rover on Dec. 12, 2024, the 4,391st Martian […]
