NASA’s Ingenuity Mars Helicopter, right, stands near the apex of a sand ripple in an image taken by Perseverance on Feb. 24, 2024, about five weeks after the rotorcraft’s final flight. Part of one of Ingenuity’s rotor blades lies on the surface about 49 feet (15 meters) west of helicopter (at left in image). Credit: NASA/JPL-Caltech/LANL/CNES/CNRS

This artistic illustration shows how the early Earth might have looked under bombardment, with circular impact features dotting the daylight side, while hot lava glows on the night side. A thick, yellowish hazy atmosphere is also present. SwRI scientists created a new model for impact-generated outgassing on the early Earth. Image Courtesy of Simone Marchi (SwRI).

The north polar region of Jupiter’s volcanic moon Io was captured by NASA’s Juno during the spacecraft’s 57th close pass of the gas giant on Dec. 30, 2023. Data from recent flybys is helping scientists understand Io’s interior. Credit: Image data: NASA/JPL-Caltech/SwRI/MSSS Image processing by Gerald Eichstädt
