  • A United Launch Alliance Atlas V rocket lifts off from Space Launch Complex 3 at Vandenberg Air Force Base, California, carrying NASA's Interior Exploration using Seismic Investigations, Geodesy and Heat Transport, or InSight, Mars lander. Liftoff was at 4:05 a.m. PDT (7:05 a.m. EDT). The spacecraft will be the first mission to look deep beneath the Martian surface. It will study the planet's interior by measuring its heat output and listen for marsquakes. InSight will use the seismic waves generated by marsquakes to develop a map of the planet’s deep interior. The resulting insight into Mars’ formation will provide a better understanding of how other rocky planets, including Earth, were created.

  • Jun 22, 2017 - Space - This image was acquired by the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter on April 18, 2017, at 14:04 local Mars time. It reminded the HiRISE team of the rugged and open terrain of a stark shore-line, perhaps of the British Isles. A close-up in enhanced color produces a striking effect, giving the impression of a cloud-covered cliff edge with foamy waves crashing against it. The reality is that the surface of Mars is much dryer than our imaginations might want to suggest. Dunes visible below the cliff, give the impression of an ocean surface, complete with foam capped waves crashing against the 'shore line,' demonstrating the abstract similarity between the nature of a turbulent ocean and a Martian dune field.

  • On a clear day, Heard Island stands as a small drumstick-shaped patch of rock and snow amidst a vast expanse of blue. Located in the southwestern Indian Ocean and only accessible by boat, the small volcanic island is situated 4,000 kilometers southwest of Western Australia, 4,700 kilometers southeast of Africa, and 1,000 kilometers north of Antarctica.<br />
When the Operational Land Imager (OLI) on Landsat 8 captured this image of Heard Island, just the tip of Mawson Peak - the highest point on the island - was visible through the sheet of marine stratocumulus clouds swirling over this part of the Furious Fifties. Though just 2,745 meters (9,006 feet), the mountain was tall enough to stir up several cloud vortices that swirled downwind like eddies in a fast-moving river.<br />
Theodore von Kármán, a Hungarian-American physicist, was the first to describe the physical processes that create long chains of spiral eddies like the ones shown above. Known as von Kármán vortices, the patterns can form nearly anywhere that fluid flow is disturbed by an object. In this case, the unique flow occurs as winds streamed around Mawson Peak. As winds were diverted around the mountain, the disturbance in the flow propagated downstream in the form of vortices that alternate their direction of rotation.<br />
Often, von Kármán vortices form relatively straight lines of eddies; in this case, powerful southerly winds appear to be pushing the vortices northward. You can view the scene on the Worldview browser to get a broader view of the vortices trailing north.<br />

Zachariæ Isstrøm has become the latest Greenland glacier to undergo rapid changes in a warming world. Research published November 2015 in Science found that Zachariæ Isstrøm broke loose from a stable position in 2012 and entered a phase of accelerated retreat.<br />
The consequences will be felt for decades to come. The reason? Zachariæ Isstrøm is big. It drains ice from a 91,780 square kilometer (35,440 square mile) area of northeast Greenland. That's about 5 percent of the Greenland Ice Sheet. The glacier holds enough water to raise global sea level by more than 46 centimeters (18 inches) if it were to melt completely. It is already shedding billions of tons of ice into the far North Atlantic each year.<br />
"North Greenland glaciers are changing rapidly," said lead author Jeremie Mouginot of the University of California, Irvine (UCI). "The shape and dynamics of Zachariæ Isstrøm have changed dramatically over the last few years. The glacier is now breaking up and calving high volumes of icebergs into the ocean, which will result in rising sea levels for decades to come."<br />
The change is apparent in the images above. The top image was acquired by the Enhanced Thematic Mapper Plus (ETM+) on Landsat 7 on August 5, 1999, when the glacier was stable. The second image was acquired on August 2, 2015, with the Operational Land Imager (OLI) on Landsat 8. The second image shows how the ice shelf and glacier have melted and retreated substantially. Turn on the image comparison tool to see the difference.<br />
As of 2015, the glacier is losing 5 billion tons of ice every year. The time-lapse animation above shows the glacier's retreat during the 2015 melt season. The animation is composed of 26 natural-color images acquired by Landsat 8 from May 19 through October 1, 2015.<br />
To better understand the changes taking place at Zachariæ Isstrøm, Mouginot and his colleagues from NASA's Jet Propulsion Laboratory (JPL), and the University of Kansas compil

  • May 1, 2019 - Mars Surface - NASA's InSight lander used the Instrument Deployment Camera (IDC) on the end of its robotic arm to image this sunset on Mars on April 25, 2019, the 145th Martian day, or sol, of the mission. This was taken around 6:30 p.m. Mars local time. This color-corrected version more accurately shows the image as the human eye would see it. The first mission to send back such images was the Viking 1 lander, which captured a sunset on Aug. 21, 1976; Viking 2 captured a sunrise on June 14, 1978. Since then, both sunrises and sunsets have been recorded by the Spirit, Opportunity and Curiosity rovers, among other missions. (Credit Image: © JPL-Caltech/NASA via ZUMA Wire/ZUMAPRESS.com)

  • June 15, 2018 - Mars Surface - This HiRISE image from NASA's Mars Reconnaissance Orbiter (MRO) captures a new, dated (within about a decade) impact crater that triggered a slope streak. When the meteoroid hit the surface and exploded to make the crater, it also destabilized the slope and initiated this avalanche. The crater itself is only 5 meters across, but the streak it started is 1 kilometer long! Slope streaks are created when dry dust avalanches leave behind dark swaths on dusty Martian hills. The faded scar of an old avalanche is also visible to the side of the new dark streak. (Credit Image: © JPL-Caltech/NASA via ZUMA Wire/ZUMAPRESS.com)

  • August 7, 2017 - Space - The thin sliver of Saturn's moon Prometheus lurks near ghostly structures in Saturn's narrow F ring in this view from NASA's Cassini spacecraft. Many of the narrow ring's faint and wispy features result from its gravitational interactions with Prometheus (86 kilometers, or 53 miles across).Visible here is a distinct difference in brightness between the outermost section of Saturn's A ring (left of center) and rest of the ring, interior to the Keeler Gap (lower left). This view looks toward the sunlit side of the rings from about 13 degrees above the ring plane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on May 13, 2017. The view was acquired at a distance of approximately 680,000 miles (1.1 million kilometers) from Saturn. Image scale is 4 miles (6 kilometers) per pixel.

Along the limb (the planet's edge) at left can be seen a thin, detached haze. Cassini will pass through Saturn's upper atmosphere during the final five orbits of the mission, before making a fateful plunge into Saturn on Sept. 15, 2017. When Cassini plunges toward Saturn to meet its fate, contact with the spacecraft is expected to be lost before it reaches the depth of this haze. This view is a false-color composite made on July 16, 2017, at a distance of about 777,000 miles from Saturn. (Credit Image: © NASA/JPL-Caltech/ZUMA Wire/ZUMAPRESS.com)

  • Jul 21, 2017 - Mars Surface - Toward the right side of this enhanced-color scene is a broad notch in the crest of the western rim of Endeavour Crater on Mars. Wheel tracks in that area were left by NASA's Mars Exploration Rover Opportunity as it observed 'Perseverance Valley' from above in the spring of 2017. The valley is a major destination for the rover's extended mission. It descends out of sight on the inner slope of the rim, extending down and eastward from that notch. Opportunity's panoramic camera (Pancam) took the component images for this view from a position outside the crater during the span of June 7 to June 19, 2017, sols 4753 to 4765 of the rover's work on Mars. This scene includes features that might have been ancient channels from water, ice or wind moving toward the notch in the rim, which might have been a spillway. Perseverance Valley, just on the other side, was likely carved by action of some fluid, such as water, water-lubricated debris, or wind. The mission is investigating to learn more about that process from evidence in place. (Credit Image: © NASA/JPL-Caltech/Cornell/ZUMA Wire/ZUMAPRESS.com)

  • March 27, 2017 - Space - From high above Saturn's northern hemisphere, NASA's Cassini spacecraft gazes over the planet's north pole, with its intriguing hexagon and bullseye-like central vortex. Saturn's moon Mimas is visible as a mere speck near upper right. At 246 miles (396 kilometers across) across, Mimas is considered a medium-sized moon. It is large enough for its own gravity to have made it round, but isn't one of the really large moons in our solar system, like Titan. Even enormous Titan is tiny beside the mighty gas giant Saturn. This view looks toward Saturn from the sunlit side of the rings, from about 27 degrees above the ring plane. The image was taken in green light with the Cassini spacecraft wide-angle camera.

  • May 8, 2017 - Space - Saturn's hexagonal polar jet stream is the shining feature of almost every view of the north polar region of Saturn. The region, in shadow for the first part of the Cassini mission, now enjoys full sunlight, which enables Cassini scientists to directly image it in reflected light. Although the sunlight falling on the north pole of Saturn is enough to allow us to image and study the region, it does not provide much warmth. In addition to being low in the sky (just like summer at Earth's poles), the sun is nearly ten times as distant from Saturn as from Earth. This results in the sunlight being only about 1 percent as intense as at our planet. This view looks toward Saturn from about 31 degrees above the ring plane. The image was taken with the Cassini spacecraft wide-angle camera on Jan. 22, 2017 using a spectral filter which preferentially admits wavelengths of near-infrared light centered at 939 nanometers.

  • May 4, 2017 - U.S. - Thanks to observatories such as NASA's Kepler space telescope, we know that two-star systems can indeed support planets, although planets discovered so far around double-star systems are large and gaseous. It turns out, such a planet could be quite hospitable if located at the right distance from its two stars, and wouldn't necessarily even have deserts. This illustration shows a hypothetical planet covered in water around the binary star system of Kepler-35A and B. In reality, the stellar pair Kepler-35A and B host a planet called Kepler-35b, a giant planet about eight times the size of Earth, with an orbit of 131.5 Earth days.

  • April 30, 2019 - California, U.S. - The Orbiting Carbon Observatory 3, or OCO-3, sits on the large vibration table (known as the 'shaker') in the Environmental Test Lab at the Jet Propulsion Laboratory. The exposed wires lead to sensors used during dynamics and thermal-vacuum testing. Thermal blankets will be added to the instrument at Kennedy Space Center, where a Space-X Dragon capsule carrying OCO-3 is slated to launch it to the International Space Station to observe near-global measurements of carbon dioxide on land and sea, from just after sunrise to just before sunset. That makes it far more versatile and powerful than its predecessor. (Credit Image: ? JPL-Caltech/NASA via ZUMA Wire/ZUMAPRESS.com)

  • April 23, 2018 - Space - Image Released Today: Saturn's rings display their subtle colors in this view captured on Aug. 22, 2009, by NASA's Cassini spacecraft. The particles that make up the rings range in size from smaller than a grain of sand to as large as mountains, and are mostly made of water ice. The exact nature of the material responsible for bestowing color on the rings remains a matter of intense debate among scientists. Images taken using red, green and blue spectral filters were combined to create this natural color view. Cassini's narrow-angle camera took the images at a distance of approximately 1.27 million miles (2.05 million kilometers) from the center of the rings.

Until future missions are sent to Saturn, Cassini's image-rich legacy must suffice.Because Earth is closer to the Sun than Saturn, observers on Earth only see Saturn's day side. With spacecraft, we can capture views (and data) that are simply not possible from Earth, even with the largest telescopes.

  • Aug 14, 2017 - Space - NASA's Cassini spacecraft looks toward the night side of Saturn's moon Titan in a view that highlights the extended, hazy nature of the moon's atmosphere. During its long mission at Saturn, Cassini has frequently observed Titan at viewing angles like this, where the atmosphere is backlit by the Sun, in order to make visible the structure of the hazes. Titan's high-altitude haze layer appears blue here, whereas the main atmospheric haze is orange. The difference in color could be due to particle sizes in the haze. The blue haze likely consists of smaller particles than the orange haze. (Credit Image: © JPL-Caltech/SSI/NASA via ZUMA Wire/ZUMAPRESS.com)

  • Jun 28, 2017 - Mars Orbit - Various researchers are often pre-occupied with the quest for flowing water on Mars. However, this image from NASA's Mars Reconnaissance Orbiter (MRO), shows one of the many examples from Mars where lava (when it was molten) behaved in a similar fashion to liquid water. This image covers the three falls in the north-central region of the crater wall. The lava flows and falls are distinct as they are rougher than the original features that are smooth and knobby. In a close-up image the rough-textured lava flow to the north has breached the crater wall at a narrow point, where it then cascades downwards, fanning out and draping the steeper slopes of the wall in the process.

  • May 19, 2017 - Space - NASA's Juno spacecraft was racing away from Jupiter following its seventh close pass of the planet when JunoCam snapped this image on May 19, 2017, from about 29,100 miles (46,900 kilometers) above the cloud tops. The spacecraft was over 65.9 degrees south latitude, with a lovely view of the south polar region of the planet. This image was processed to enhance color differences, showing the amazing variety in Jupiter's stormy atmosphere. Four of the white oval storms known as the "String of Pearls" are visible near the top of the image. Interestingly, one orange-colored storm can be seen at the belt-zone boundary, while other storms are more of a cream color. (Credit Image: © JPL-Caltech/SwRI/MSSS/NASA via ZUMA Wire/ZUMAPRESS.com)

  • May 5, 2017 - Space - This 360-degree mosaic from the Mast Camera (Mastcam) on NASA's Curiosity Mars rover looks out over a portion of the Bagnold Dunes, which stretch for several miles. From early February to early April 2017, the rover examined four sites near linear dunes for comparison with what it found in late 2015 and early 2016 during its investigation of crescent-shaped dunes. This two-phase campaign is the first close-up study of active dunes anywhere other than Earth. The dark, rippled surface of a linear dune is visible at the center of the view and receding into the distance to the left. The bedrock of the Murray formation, made from sediments deposited in lakes billions of years ago, is in the foreground, along with some components of the rover. The location, called "Ogunquit Beach," is on the northwestern flank of lower Mount Sharp. (Credit Image: © JPL-Caltech/MSSS/NASA via ZUMA Wire/ZUMAPRESS.com)

  • Jun 9, 2017 - Space - This image from NASA's Dawn spacecraft shows the northeastern rim of Urvara Crater on Ceres at lower left. To the right of the crater, the long, narrow feature that appears to jut out toward the north is called Pongal Catena, which is about 60 miles (96 km) long. Catenae are large grooves or troughs that can have various origins. They refer to chains of closely connected craters formed by a series of impacts, as found on Jupiter's moon Ganymede. They can also represent large faults created by internal forces, for example in this example found on Mars (see PIA20441). The mechanism that formed Pongal Catena is not understood yet, but it likely formed as a consequence of the stresses generated by the large impacts that resulted in the formation of the Urvara and Yalode craters.
