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.

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.
