Rim of Endeavour Crater on Mars - This scene shows the "Murray Ridge" portion of the western rim of Endeavour Crater on Mars. The ridge is the NASA's Mars Exploration Rover Opportunity's work area for the rover's sixth Martian winter. The ridge rises about 130 feet (40 meters) above the surrounding plain, between "Solander Point" at the north end of the ridge and "Cape Tribulation," beyond Murray Ridge to the south. This view does not show the entire ridge. The visible ridge line is about 10 meters (33 feet) above the rover's location when the component images were taken. The rover team chose to call this feature Murray Ridge in tribute to Bruce Murray (1931-2013), an influential advocate for planetary exploration who was a member of the science teams for NASA's earliest missions to Mars and later served as director of NASA's Jet Propulsion Laboratory, in Pasadena. This view is presented in approximately true color, merging exposures taken through three of the Pancam's color filters, centered on wavelengths of 753 nanometers (near-infrared), 535 nanometers (green) and 432 nanometers (violet).

On this date in history, Dec. 7, 1972, the Apollo 17 crew snap this iconic "blue marble" photograph of the Earth. This is the original caption: View of the Earth as seen by the Apollo 17 crew traveling toward the moon. This translunar coast photograph extends from the Mediterranean Sea area to the Antarctica south polar ice cap. This is the first time the Apollo trajectory made it possible to photograph the south polar ice cap. Note the heavy cloud cover in the Southern Hemisphere. Almost the entire coastline of Africa is clearly visible. The Arabian Peninsula can be seen at the northeastern edge of Africa. The large island off the coast of Africa is the Malagasy Republic. The Asian mainland is on the horizon toward the northeast. The mission was the final in a series of three J-type missions planned for the Apollo Program. These J-type missions can be distinguished from previous G- and H-series missions by extended hardware capability, larger scientific payload capacity and by the use of the battery-powered Lunar Roving Vehicle, or LRV.

Astronaut Rick Mastracchio (@AstroRM) tweeted this image on Dec. 4 from the #ISS and wrote, “A wider view of New Caledonia with the sun glint you can see the water ways and other features.” Rick is taking photos from the orbiting outpost some 240 miles up circling the Earth every 90 minutes. The International Space Station (ISS) continues the NASA tradition of Earth observation from human-tended spacecraft. Operational since November 2000, the ISS is well suited for documenting Earth features and provides an excellent stage for observing most populated areas of the world. Images coming down from the International Space Station are processed on a daily basis and include over 1.2 million images through Nov. 1, 2013.

Thinking Inside the Box, Launching into Space – This image is an artist concept of two tiny, cube-shaped research satellites that hitched a ride to Earth orbit to validate new hardware and software technologies for future NASA Earth-observing instruments. The cube satellites, or “CubeSats,” which typically have a volume of exactly 33.814 ounces (1 liter), were launched on a United Launch Alliance Atlas V rocket at 11:14 p.m. PST, Dec. 5, from California's Vandenberg Air Force Base as part of the NROL-39 GEMSat mission. These two CubeSats will help enable near-real-time processing capabilities relevant to future climate science measurements. IPEX will demonstrate software that will enable future NASA missions to recognize science events such as flooding, volcanism and wildfires, and respond by sending alerts and autonomously acquiring follow-up imagery,” said Steve Chien of JPL, principal investigator for the IPEX mission. The other CubeSat launched is the Michigan Multipurpose Mini-satellite/CubeSat On-board processing Validation Experiment, or M-Cubed/COVE.

Beginning to build an engineering marvel - Assembly of the International Space Station began 15 years ago on Dec. 6, 1998, when the crew of space shuttle mission STS-88 attached the U.S.-built Unity node and the Russian-built Zarya module together in orbit. The crew carried a large-format IMAX camera, used to take this image of Unity lifted out of Endeavour's payload bay to position it upright for connection to Zarya. Zarya, launched on Nov. 20, 1998, was the first piece of the International Space Station. Also known as the Functional Cargo Block (FGB), it would provide a nucleus of orientation control, communications and electrical power while the station waited for its other elements. Two weeks later, on Dec. 4, 1998, NASA's space shuttle Endeavour launched Unity, the first U.S. piece of the complex, during the STS-88 mission.

The James Webb Space Telescope 's MIRI Shield Dropping in on Dropping Temperatures - Goddard Technicians Tony Kiem (left) and George Mooney (right) guide the craned structure holding the Webb telescope's Mid-Infrared Instrument, or MIRI Shield Environmental Test Unit, into place in a cryogenic (cooling) test chamber. This shield will be used to simulate the MIRI instrument during prelaunch testing to verify that the MIRI cooling system will function properly in space. Goddard Safety Engineer Richard Bowlan watches from above. The James Webb Space Telescope (sometimes called JWST) is a large, infrared-optimized space telescope. The project is working to a 2018 launch date. Webb will find the first galaxies that formed in the early Universe, connecting the Big Bang to our own Milky Way Galaxy. Webb will peer through dusty clouds to see stars forming planetary systems, connecting the Milky Way to our own Solar System. Webb's instruments will be designed to work primarily in the infrared range of the electromagnetic spectrum, with some capability in the visible range.

Orion Heat Shield Transported Aboard Super Guppy Plane: The heat shield for NASA's Orion spacecraft was loaded onto a Super Guppy plane in Manchester, N.H. on Dec. 4, for transport to Kennedy Space Center in Florida. The heat shield, the largest of its kind ever built, is being unloaded Thursday, Dec. 5, and is scheduled for installation on Orion in March 2014. The heat shield will be used in September 2014 during Exploration Flight Test-1, a two-orbit flight that will take an uncrewed Orion capsule to an altitude of 3,600 miles. The returning capsule is expected to encounter temperatures of almost 4,000 degrees Fahrenheit as it travels through Earth's atmosphere at up to 20,000 mph, faster than any spacecraft in the last 40 years. Data gathered during the flight will influence decisions about design improvements on the heat shield and other Orion systems, authenticate existing computer models, and innovative new approaches to space systems and development. It also will reduce overall mission risks and costs for future Orion missions, which include exploring an asteroid and Mars.

In Full View: Saturn's Streaming Hexagon - This colorful view from NASA's Cassini mission is the highest-resolution view of the unique six-sided jet stream at Saturn's north pole known as "the hexagon." This movie, made from images obtained by Cassini's imaging cameras, is the first to show the hexagon in color filters, and the first movie to show a complete view from the north pole down to about 70 degrees north latitude. This movie shows a view from directly over the north pole, keeping up with the rotation of the planet so that all the motion seen on the screen is the motion of the hexagonal jet stream or the storms inside of it, without any added motion from the spinning of the planet itself. The original images were re-projected to show this polar view. High-resolution views of the hexagon have only recently become possible because of the changing of the seasons at Saturn and changes in the Cassini spacecraft’s orbit. The north pole was dark when Cassini first arrived in July 2004. The sun really only began to illuminate the entire interior of the hexagon in August 2009, with the start of northern spring. In late 2012, Cassini began making swings over Saturn's poles, giving it better views of the hexagon.

Forty years ago, Pioneer 10 made its closest approach to Jupiter. On Dec. 4, 1973, NASA's Pioneer 10 spacecraft sent back images of Jupiter’s ever-increasing size. The most dramatic moment was after closest approach and after the spacecraft was hidden behind Jupiter. Here, images gradually build up into a very distorted crescent-shaped Jupiter. "Sunrise on Jupiter," a team member said. The giant planet crescent gradually decreased in size as the spacecraft sped away out of the Jovian system. Launched on Mar. 2, 1972, Pioneer 10 was the first spacecraft to travel through the asteroid belt, and the first spacecraft to make direct observations and obtain close-up images of Jupiter. Pioneer 10 passed within 81,000 miles of the cloudtops during its closest encounter with Jupiter. This historic event marked humans' first approach to Jupiter and opened the way for exploration of the outer solar system - for Voyager to tour the outer planets, for Ulysses to break out of the ecliptic, for Galileo to investigate Jupiter and its satellites, and for Cassini to go to Saturn and probe Titan. During its Jupiter encounter, Pioneer 10 imaged the planet and its moons, and took measurements of Jupiter's magnetosphere, radiation belts, magnetic field, atmosphere, and interior. These measurements of the intense radiation environment near Jupiter were crucial in designing the Voyager and Galileo spacecraft.

View of the Transantarctic Mountains: This image taken from the NASA P-3 airborne laboratory on Nov. 27, 2013, near the end of the 2013 IceBridge Antarctic campaign. NASA’s Operation IceBridge images Earth's polar ice in unprecedented detail to better understand processes that connect the polar regions with the global climate system. IceBridge utilizes a highly specialized fleet of research aircraft and the most sophisticated suite of innovative science instruments ever assembled to characterize annual changes in thickness of sea ice, glaciers, and ice sheets. In addition, IceBridge collects critical data used to predict the response of earth’s polar ice to climate change and resulting sea-level rise. IceBridge also helps bridge the gap in polar observations between NASA's ICESat satellite missions.

What was the fate of #Comet #ISON? Scientists are still unsure. There is no doubt that the comet shrank in size considerably as it rounded the sun and there's no doubt that something made it out on the other side to shoot back into space. The question remains as to whether the bright spot seen moving away from the sun was simply debris, or whether a small nucleus of the original ball of ice was still there. Regardless, it is likely that it is now only dust. By monitoring its changes in brightness over time, scientists can estimate whether there's a nucleus or not, but our best chance at knowing for sure will be if the Hubble Space Telescope makes observations later in December 2013. In this time-lapse image, Comet ISON comes in from the bottom right and moves out toward the upper right, getting fainter and fainter. This image is from the ESA/NASA Solar and Heliospheric Observatory. The image of the sun at the center is from NASA's Solar Dynamics Observatory.

Sunlit Edge of Saturn's Largest Moon, Titan: The sunlit edge of Titan's south polar vortex stands out distinctly against the darkness of the moon's unilluminated hazy atmosphere. The Cassini spacecraft images of the vortex led scientists to conclude that its clouds form at a much higher altitude -- where sunlight can still reach -- than the surrounding haze. Titan (3,200 miles, or 5,150 kilometers across) is Saturn's largest moon. This view looks toward the trailing hemisphere of Titan. North on Titan is up and rotated 32 degrees to the left. The image was taken with the Cassini spacecraft narrow-angle camera on July 14, 2013 using a spectral filter sensitive to wavelengths of near-infrared light centered at 938 nanometers. The view was obtained at a distance of approximately 808,000 miles (1.3 million kilometers) from Titan and at a Sun-Titan-spacecraft, or phase, angle of 82 degrees. Image scale is 5 miles (8 kilometers) per pixel. Image Credit: NASA/JPL-Caltech/Space Science Institute #nasa #space #saturn #titan #moon #cassini #clouds; -
What does a volcanic eruption look like from the #ISS? When viewing conditions are favorable, astronauts on the International Space Station (ISS) can take unusual and striking images of the Earth. This photograph provides a view of an eruption plume emanating from Kliuchevskoi, one of the many active volcanoes on the Kamchatka Peninsula. The nadir views—looking straight down—acquired by most satellites tend to flatten the landscape and reduce our sense of three-dimensional topography. In contrast, this photo was taken from the ISS with an oblique viewing angle that gives a strong sense of three dimensions, which are also accentuated by the shadows cast by the volcanic peaks. The result is a view similar to what you might see from a low-altitude airplane. The image was taken when the ISS was located over a ground position more than 1,500 kilometers (900 miles) to the southwest. The plume—likely a combination of steam, volcanic gases, and ash—stretched to the east-southeast due to prevailing winds. The dark region to the north-northwest is likely a product of shadows and of ash settling out. Several other volcanoes are visible in the image, including Ushkovsky, Tolbachik, Zimina, and Udina. To the south-southwest of Kliuchevskoi lies Bezymianny Volcano, which appears to be emitting a small steam plume (at image center).
