This image from InSight’s robotic-arm mounted Instrument Deployment Camera shows the instruments on the spacecraft’s deck, with the Martian surface of Elysium Planitia in the background. The color-calibrated picture was acquired on December 4, 2018 (Sol 8); in the foreground, a copper-colored hexagonal cover protects the SEIS seismometer; the gray dome behind SEIS is the wind and thermal shield, which will be placed over SEIS; to the left is a black cylindrical instrument, the Heat Flow and Physical Properties Probe (HP3); HP3 will drill up to 16 feet (5 m) below the Martian surface, measuring heat released from the interior of the planet; above the deck is InSight’s robotic arm, with the stowed grapple directly facing the camera; to the right can be seen a small portion of one of the two solar panels that help power InSight and part of the UHF communication antenna.

InSight flipped open the lens cover on its Instrument Context Camera (ICC) on November 30, 2018, and captured this view of Mars. Located below the deck of the InSight lander, the ICC has a fisheye view, creating a curved horizon. Some clumps of dust are still visible on the camera’s lens. One of the spacecraft’s footpads can be seen in the lower right corner. The seismometer’s tether box is in the upper left corner. Image credit: NASA / JPL-Caltech.

This image captured by NASA’s Juno orbiter shows a multitude of magnificent, swirling clouds in Jupiter’s North North Temperate Belt. The image was taken at 4:58 p.m. EDT on October 29, 2018 (1:58 p.m. PDT) as the spacecraft performed its 16th close flyby of Jupiter. At the time, Juno was about 4,400 miles (7,000 km) from the planet’s cloud tops, at a latitude of approximately 40 degrees north.

Three waves can be seen in this image, which is an excerpt of a JunoCam image taken on February 2, 2017, during Juno’s fourth flyby of Jupiter. The region imaged in this picture is part of the visibly dark band just north of Jupiter’s equator known as the North Equatorial Belt. Most of this belt is characterized by downwelling motions, but during the fourth flyby it had several bright areas of upwelling clouds. One of those upwelling clouds appears to be accompanied by dark regions, which are most likely shadows. The shadow associated with the center of the three waves is about 25 miles (40 km) long; from the angle of illumination, researchers deduced that the shadowed part of the wave must be around 4 miles (7 km) above the main cloud deck, with the peak of the wave probably close to 6 miles (10 km) above the main cloud deck.

This mosaic of images from the MDIS Narrow Angle Camera on NASA’s MESSENGER spacecraft shows the impact crater Hokusai, located on Mercury at a latitude of 58°N. The crater has an impressive system of rays, which extend as much as a thousand kilometers (more than 600 miles) across the planet and are the longest that have yet been identified on Mercury.

Mosaic of the Valles Marineris hemisphere of Mars projected into point perspective, a view similar to that which one would see from a spacecraft. The distance is 1,550 miles (2,500 km) from the surface of the planet. The mosaic is composed of 102 Viking Orbiter images of Mars. The center of the scene shows the entire Valles Marineris canyon system, over 1,240 miles (2,000 km) long and up to 5 miles (8 km) deep, extending form Noctis Labyrinthus, the arcuate system of graben to the west, to the chaotic terrain to the east. Many huge ancient river channels begin from the chaotic terrain from north-central canyons and run north. The three Tharsis volcanoes (dark red spots), each about 15.5 miles (25 km) high, are visible to the west. South of Valles Marineris is very ancient terrain covered by many impact craters.

This Pluto mosaic was made from New Horizons LORRI images taken on July 14, 2015, from a distance of 49,700 miles (80,000 km). This view is projected from a point 1,118 miles (1,800 km) above Pluto’s equator, looking northeast over the dark, cratered Cthulhu Regio toward the bright, smooth expanse of icy plains called Sputnik Planum. Pluto’s North Pole is off the image to the left. This mosaic was produced with panchromatic images from the New Horizons LORRI camera, with color overlaid from the Ralph color mapper onboard New Horizons. Image credit: S.A. Stern et al.
