These are all real pictures, sent recently by our planetary missions throughout the solar system. You’ll find more of our images at solarsystem.nasa.gov/galleries, images.nasa.gov and www.jpl.nasa.gov/spaceimages.
Applying Wallpaper: 1. Click on the screen resolution you would like to use. 2. Right-click on the image (control-click on a Mac) and select the option ‘Set the Background’ or 'Set as Wallpaper’ (or similar).
1. The Fault in Our Mars
This image from our Mars Reconnaissance Orbiter (MRO) of northern Meridiani Planum shows faults that have disrupted layered deposits. Some of the faults produced a clean break along the layers, displacing and offsetting individual beds.

2. Jupiter Blues
Our Juno spacecraft captured this image when the spacecraft was only 11,747 miles (18,906 kilometers) from the tops of Jupiter’s clouds – that’s roughly as far as the distance between New York City and Perth, Australia. The color-enhanced image, which captures a cloud system in Jupiter’s northern hemisphere, was taken on Oct. 24, 2017, when Juno was at a latitude of 57.57 degrees (nearly three-fifths of the way from Jupiter’s equator to its north pole) and performing its ninth close flyby of the gas giant planet.

3. A Farewell to Saturn
After more than 13 years at Saturn, and with its fate sealed, our Cassini spacecraft bid farewell to the Saturnian system by firing the shutters of its wide-angle camera and capturing this last, full mosaic of Saturn and its rings two days before the spacecraft’s dramatic plunge into the planet’s atmosphere on Sept. 15, 2017.

4. All Aglow
Saturn’s moon Enceladus drifts before the rings, which glow brightly in the sunlight. Beneath its icy exterior shell, Enceladus hides a global ocean of liquid water. Just visible at the moon’s south pole (at bottom here) is the plume of water ice particles and other material that constantly spews from that ocean via fractures in the ice. The bright speck to the right of Enceladus is a distant star. This image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 6, 2011.

5. Rare Encircling Filament
Our Solar Dynamics Observatory came across an oddity this week that the spacecraft has rarely observed before: a dark filament encircling an active region (Oct. 29-31, 2017). Solar filaments are clouds of charged particles that float above the Sun, tethered to it by magnetic forces. They are usually elongated and uneven strands. Only a handful of times before have we seen one shaped like a circle. (The black area to the left of the brighter active region is a coronal hole, a magnetically open region of the Sun).

6. Jupiter’s Stunning Southern Hemisphere
See Jupiter’s southern hemisphere in beautiful detail in this image taken by our Juno spacecraft. The color-enhanced view captures one of the white ovals in the “String of Pearls,” one of eight massive rotating storms at 40 degrees south latitude on the gas giant planet. The image was taken on Oct. 24, 2017, as Juno performed its ninth close flyby of Jupiter. At the time the image was taken, the spacecraft was 20,577 miles (33,115 kilometers) from the tops of the clouds of the planet.

7. Saturn’s Rings: View from Beneath
Our Cassini spacecraft obtained this panoramic view of Saturn’s rings on Sept. 9, 2017, just minutes after it passed through the ring plane. The view looks upward at the southern face of the rings from a vantage point above Saturn’s southern hemisphere.

8. From Hot to Hottest
This sequence of images from our Solar Dynamics Observatory shows the Sun from its surface to its upper atmosphere all taken at about the same time (Oct. 27, 2017). The first shows the surface of the sun in filtered white light; the other seven images were taken in different wavelengths of extreme ultraviolet light. Note that each wavelength reveals somewhat different features. They are shown in order of temperature, from the first one at about 11,000 degrees Fahrenheit (6,000 degrees Celsius) on the surface, out to about 10 million degrees in the upper atmosphere. Yes, the sun’s outer atmosphere is much, much hotter than the surface. Scientists are getting closer to solving the processes that generate this phenomenon.

9. High Resolution View of Ceres
This orthographic projection shows dwarf planet Ceres as seen by our Dawn spacecraft. The projection is centered on Occator Crater, home to the brightest area on Ceres. Occator is centered at 20 degrees north latitude, 239 degrees east longitude.

10. In the Chasm
This image from our Mars Reconnaissance Orbiter shows a small portion of the floor of Coprates Chasma, a large trough within the Valles Marineris system of canyons. Although the exact sequence of events that formed Coprates Chasma is unknown, the ripples, mesas, and craters visible throughout the terrain point to a complex history involving multiple mechanisms of erosion and deposition. The main trough of Coprates Chasma ranges from 37 miles (60 kilometers) to 62 miles (100 kilometers) in width.

The Artemis I Mission: To the Moon and Back
The Artemis I mission was the first integrated test of the Orion spacecraft, the Space Launch System (SLS) rocket, and Exploration Ground Systems at NASA’s Kennedy Space Center in Florida. We’ll use these deep space exploration systems on future Artemis missions to send astronauts to the Moon and prepare for our next giant leap: sending the first humans to Mars.
Take a visual journey through the mission, starting from launch, to lunar orbit, to splashdown.
Liftoff
The SLS rocket carrying the Orion spacecraft launched on Nov. 16, 2022, from Launch Complex 39B at NASA’s Kennedy Space Center in Florida. The world’s most powerful rocket performed with precision, meeting or exceeding all expectations during its debut launch on Artemis I.
"This is Your Moment"
Following the successful launch of Artemis I, Launch Director Charlie Blackwell-Thompson congratulates the launch team.
“The harder the climb, the better the view,” she said. “We showed the space coast tonight what a beautiful view it is.”
That's Us
On Orion’s first day of flight, a camera on the tip of one of Orion’s solar arrays captured this image of Earth.
Inside Orion
On the third day of the mission, Artemis I engineers activated the Callisto payload, a technology demonstration developed by Lockheed Martin, Amazon, and Cisco that tested a digital voice assistant and video conferencing capabilities in a deep space environment. In the image, Commander Moonikin Campos occupies the commander’s seat inside the spacecraft. The Moonikin is wearing an Orion Crew Survival System suit, the same spacesuit that Artemis astronauts will use during launch, entry, and other dynamic phases of their missions. Campos is also equipped with sensors that recorded acceleration and vibration data throughout the mission that will help NASA protect astronauts during Artemis II. The Moonikin was one of three “passengers” that flew aboard Orion. Two female-bodied model human torsos, called phantoms, were aboard. Zohar and Helga, named by the Israel Space Agency (ISA) and the German Aerospace Center (DLR) respectively, supported the Matroshka AstroRad Radiation Experiment (MARE), an experiment to provide data on radiation levels during lunar missions. Snoopy, wearing a mock orange spacesuit, also can be seen floating in the background. The character served as the zero-gravity indicator during the mission, providing a visual signifier that Orion is in space.
Far Side of the Moon
A portion of the far side of the Moon looms large in this image taken by a camera on the tip of one of Orion’s solar arrays on the sixth day of the mission.
First Close Approach
The Orion spacecraft captured some of the closest photos of the Moon from a spacecraft built for humans since the Apollo era — about 80 miles (128 km) above the lunar surface. This photo was taken using Orion’s optical navigational system, which captures black-and-white images of the Earth and Moon in different phases and distances.
Distant Retrograde Orbit
Orion entered a distant retrograde orbit around the Moon almost two weeks into the mission. The orbit is “distant” in the sense that it’s at a high altitude approximately 50,000 miles (80,467 km) from the surface of the Moon. Orion broke the record for farthest distance of a spacecraft designed to carry humans to deep space and safely return them to Earth, reaching a maximum distance of 268,563 miles (432,210 km).
Second Close Approach
On the 20th day of the mission, the spacecraft made its second and final close approach to the Moon flying 79.2 miles (127.5 km) above the lunar surface to harness the Moon’s gravity and accelerate for the journey back to Earth.
Cameras mounted on the crew module of the Orion spacecraft captured these views of the Moon’s surface before its return powered flyby burn.
Heading Home
After passing behind the far side of the Moon on Flight Day 20, Orion powered a flyby burn that lasted approximately 3 minutes and 27 seconds to head home. Shortly after the burn was complete, the Orion spacecraft captured these views of the Moon and Earth, which appears as a distant crescent.
Parachutes Deployed
Prior to entering the Earth’s atmosphere, Orion’s crew module separated from its service module, which is the propulsive powerhouse provided by ESA (European Space Agency). During re-entry, Orion endured temperatures about half as hot as the surface of the Sun at about 5,000 degrees Fahrenheit (2,760 degrees Celsius). Within about 20 minutes, Orion slowed from nearly 25,000 mph (40,236 kph) to about 20 mph (32 kph) for its parachute-assisted splashdown.
Splashdown
On Dec. 11, the Orion spacecraft splashed down in the Pacific Ocean off the coast of California after traveling 1.4 million miles (2.3 million km) over a total of 25.5 days in space. Teams are in the process of returning Orion to Kennedy Space Center in Florida. Once at Kennedy, teams will open the hatch and unload several payloads, including Commander Moonikin Campos, the space biology experiments, Snoopy, and the official flight kit. Next, the capsule and its heat shield will undergo testing and analysis over the course of several months.
