Satellite Shows Major Winter Storm Hitting the U.S. South - Clouds associated with the major winter storm that is bringing wintry precipitation and chilly temperatures to the U.S. south is the focus in an image from NOAA's GOES-East satellite today, Feb. 11 at 1815 UTC/1:15 p.m. EST. Rain, freezing rain, sleet and snow are part of the large front that stretches from eastern Texas to the Carolinas in the Geostationary Operational Environmental satellite or GOES image. NOAA's weather maps show several areas of low pressure along the frontal boundary. One low pressure is in the northern Gulf of Mexico, while the other is in the Atlantic Ocean, just south of South Carolina. NOAA's National Weather Service has been issuing watches and warnings throughout the south that extend along Mid-Atlantic east coast. The clouds and fallen snow were overlaid on a true-color image of land and ocean created by data from the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua and Terra satellites.

Landsat 8's First Year - On Feb. 11, 2013, the Landsat 8 satellite rocketed into a sunny California morning onboard a powerful Atlas V and began its life in orbit. In the year since launch, scientists have been working to understand the information the satellite has been sending back. Some have been calibrating the data—checking it against ground observations and matching it to the rest of the 42-year-long Landsat record. At the same time, the broader science community has been learning to use the new data. The map above—one of the first complete views of the United States from Landsat 8—is an example of how scientists are testing Landsat 8 data. The strips in the image above are a result of the way Landsat 8 operates. Like its predecessors, Landsat 8 collects data in 185-kilometer (115-mile) wide strips called swaths or paths. Each orbit follows a predetermined ground track so that the same path is imaged each time an orbit is repeated. It takes 233 paths and 16 days to cover all of the land on Earth.

With the help of a natural "zoom lens" in space, Hubble astronomers are looking farther than anyone has before. The first of a set of unprecedented, super-deep views of the universe contain images of some of the intrinsically faintest and youngest galaxies ever detected. This is just the first of several primary target fields in the program. The immense gravity in this foreground galaxy cluster, Abell 2744, warps space to brighten and magnify images of far-more-distant background galaxies as they looked over 12 billion years ago, not long after the big bang. The Hubble exposure reveals nearly 3,000 of these background galaxies interleaved with images of hundreds of foreground galaxies in the cluster.

Color-Coded Clues to Composition Superimposed on Martian Seasonal-Flow Image - This image combines a photograph of seasonal dark flows on a Martian slope with a grid of colors based on data collected by a mineral-mapping spectrometer observing the same area. The area is at Palikir Crater in the southern hemisphere of Mars. The photograph is from the High Resolution Imaging Science Experiment (HiRISE) camera. The composition information, as an image with pixels appearing as a grid of squares, is from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM). Both of these instruments are on NASA's Mar Reconnaissance Orbiter. The view is oriented with north toward the bottom. The scale bar at lower left indicates 90 meters (295 feet). These dark, warm-season flows are called "recurring slope lineae" or RSL. Researchers are using observations from Mars orbiters to study the possibility that RSL result from action of salty liquid water.

Until 2010, Indonesia’s Sinabung volcano was dormant, with no confirmed eruptions in the historical record. Fresh gas and ash plumes marked the arrival of a new series of eruptions. The Advanced Land Imager (ALI) on the Earth Observing-1 (EO-1) satellite collected this natural-color image of an ash plume from Sinabung on February 6, 2014. Frequent collapses from the unstable lava dome near Sinabung’s summit create pyroclastic flows that have swept at least 4.5 kilometers (2.8 miles) down the volcano’s slopes. The flow deposits are visible southeast of Sinabung’s summit and appear light gray. The eruption has coated much of the surrounding landscape with ash, causing green dark green forests to appear tan.

This view of the twilight sky and Martian horizon taken by NASA's Curiosity Mars rover includes Earth as the brightest point of light in the night sky. Earth is a little left of center in the image. Researchers used the left eye camera of Curiosity's Mast Camera (Mastcam) to capture this scene about 80 minutes after sunset on the 529th Martian day, or sol, of the rover's work on Mars (Jan. 31, 2014). The image has been processed to remove effects of cosmic rays. A human observer with normal vision, if standing on Mars, could easily see Earth and the moon as two distinct, bright "evening stars." The distance between Earth and Mars when Curiosity took the photo was about 99 million miles (160 million kilometers).

It's not often that the Winter Olympic Games come with an ocean view, but that's what we are getting this year at the Black Sea resort of Sochi, Russia. Sochi is the warmest city ever to host the winter games, which officially run from Feb. 7 through Feb. 23. This image of the Sochi Olympic venues was acquired on Jan. 4, 2014, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft. This image centers on the Rosa Khutar ski resort in the mountains near Sochi. That's where the alpine Olympic events will be held. The resort is in the valley at center, and the ski runs are visible on the shadowed slopes on the left-hand side of the valley. The runs may be rated double black diamond, but they're not quite as steep as they appear in this image. Height is exaggerated 1.5 times to bring out topographic details. In this images, red indicates vegetation, white is snow, buildings appear in gray, and the ocean is dark blue.

Orion Stage Adapter Aces Structural Loads Testing: A test article of the stage adapter that will connect the Orion spacecraft to a United Launch Alliance (ULA) Delta IV rocket for its first mission, Exploration Flight Test-1, aced structural loads testing Jan. 30. Now, the stage adapter that will fly on the Delta IV is officially ready for the journey to its final exam -- a flight more than 15 times farther into deep space than the International Space Station. For the structural loads test, the hardware was attached with lines running in different directions on the hardware. Hydraulic pressure was added to those lines in increments, which pushed on the adapter to evaluate its integrity. The test was similar to the recent "can-crush" tests on a rocket fuel tank, but the adapter wasn't purposefully buckled for the structural test as it was on the fuel tank. Twenty-five test cases were completed on the adapter. Image credit: NASA/MSFC/David Olive #nasa #orion #eft1 #exploration #flighttest #rockets #deltaiv #launch #space; -
Just weeks after NASA’s Chandra X-ray Observatory began operations in 1999, the telescope pointed at Centaurus A. This galaxy, at a distance of about 12 million light years from Earth, contains a gargantuan jet blasting away from a central supermassive black hole. Since then, Chandra has returned its attention to this galaxy, each time gathering more data. And, like an old family photo that has been digitally restored, new processing techniques are providing astronomers with a new look at this old galactic friend. As in all of Chandra’s images of Cen A, this one shows the spectacular jet of outflowing material – seen pointing from the middle to the upper left – that is generated by the giant black hole at the galaxy’s center. This new high-energy snapshot of Cen A also highlights a dust lane that wraps around the waist of the galaxy. Astronomers think this feature is a remnant of a collision that Cen A experienced with a smaller galaxy millions of years ago. Image credit: X-ray: NASA/CXC/U. Birmingham/M.

Crescent Moon Rising and Earth's Atmosphere - On Feb. 1, 2014, Japan Aerospace Exploration Agency astronaut Koichi Wakata tweeted this view of a crescent moon rising and the cusp of Earth's atmosphere. Distinct colors are visible because the dominant gases and particles in each layer of the atmosphere act as prisms, filtering out certain colors of light.

A Spectacular New Martian Impact Crater - A dramatic, fresh impact crater dominates this image taken by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter on Nov. 19, 2013. Researchers used HiRISE to examine this site because the orbiter's Context Camera had revealed a change in appearance here between observations in July 2010 and May 2012, bracketing the formation of the crater between those observations. The crater spans approximately 100 feet (30 meters) in diameter and is surrounded by a large, rayed blast zone. Because the terrain where the crater formed is dusty, the fresh crater appears blue in the enhanced color of the image, due to removal of the reddish dust in that area. Debris tossed outward during the formation of the crater is called ejecta. In examining ejecta's distribution, scientists can learn more about the impact event. The explosion that excavated this crater threw ejecta as far as 9.3 miles (15 kilometers). Image credit: NASA/JPL-Caltech/Univ. of Arizona #nasa #space #mars #crater #science #planets; -
Today in 1974, NASA's Mariner 10 mission took this first close-up photo of Venus. Made using an ultraviolet filter in its imaging system, the photo has been color-enhanced to bring out Venus's cloudy atmosphere as the human eye would see it. Venus is perpetually blanketed by a thick veil of clouds high in carbon dioxide and its surface temperature approaches 900 degrees Fahrenheit. Launched on Nov. 3, 1973 atop an Atlas-Centaur rocket, Mariner 10 flew by Venus in 1974. #nasa #space #science #venus #atlas;
