Understanding the region of interstellar space through which the solar system travels is no easy task. Interstellar space begins beyond the heliosphere, the bubble of charged particles surrounding the sun that reaches far beyond the outer planets. Voyager 1 has crossed into this space, but it’s difficult to gain a complete global picture from measurements in only one direction. Spacecraft data in the past five years from near Earth and cosmic ray observations have painted a better picture of the magnetic system that surrounds us, while at the same time raising new questions. Scientists are challenging our current understanding in a new study that combines observations of massively energetic cosmic ray particles streaming in from elsewhere in the Milky Way. The data sets show a magnetic field that is nearly perpendicular to the motion of our solar system through the galaxy. In addition to shedding light on our cosmic neighborhood, the results offer an explanation for a decades-old mystery on why we measure more incoming high-energy cosmic rays on one side of the sun than on the other. This image is a model of the interstellar magnetic fields – which would otherwise be straight -- warping around the outside of our heliosphere, based on data from NASA's Interstellar Boundary Explorer. The red arrow shows the direction in which the solar system moves through the galaxy.

No, this isn’t used for clearing snow. The crawler-transporter that will carry NASA’s Space Launch System (SLS) and Orion spacecraft to Launch Pad 39B for launch on Exploration Mission-1 in 2017 recently passed the first phase of an important milestone test at Kennedy Space Center in Florida. Testing of new traction roller bearings on crawler-transporter 2 (CT-2) was completed in late January. Engineers and technicians performed visual inspections of the roller bearing pumps, valves and lines to ensure they were working properly. For more than 45 years the crawler-transporters were used to transport the mobile launcher platform and the Apollo-Saturn V rockets and, later, space shuttles to Launch Pads 39A and B. Upgrades to CT-2 are necessary in order to increase the lifted-load capacity from 12 million to 18 million pounds to support the weight of the mobile launcher and future launch vehicles, including the SLS and Orion.

A new NASA video of NOAA's GOES satellite imagery shows three days of movement of the massive winter storm that stretches from the southern U.S. to the northeast. Visible and infrared imagery from NOAA's GOES-East or GOES-13 satellite from Feb. 10 at 1815 UTC/1:15 p.m. EST to Feb. 12 to 1845 UTC/1:45 p.m. EST were compiled into a video made by NASA/NOAA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. In the video, viewers can see the development and movement of the clouds associated with the progression of the frontal system and related low pressure areas that make up the massive storm. The video also shows the snow covered ground over the Great Lakes region and Ohio Valley that stretches to northern New England. The clouds and fallen snow data from NOAA's GOES-East satellite 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. On February 12 at 10 a.m. EST, @NOAA's National Weather Service or NWS continued to issue watches and warnings from Texas to New England. Specifically, NWS cited Winter Storm Warnings and Winter Weather Advisories were in effect from eastern Texas eastward across the interior section of southeastern U.S. states and across much of the eastern seaboard including the Appalachians. Winter storm watches are in effect for portions of northern New England as well as along the western slopes of northern and central Appalachians. For updates on local forecasts, watches and warnings, visit NOAA's www.weather.gov webpage.

Floating off into space… a set of NanoRacks CubeSats are deployed from International Space Station - The Small Satellite Orbital Deployer (SSOD), in the grasp of the Kibo laboratory robotic arm, is photographed by an Expedition 38 crew member on the space station as it deploys a set of NanoRacks CubeSats. The CubeSats program contains a variety of experiments such as Earth observations and advanced electronics testing. Station solar array panels, Earth’s horizon and the blackness of space provide the backdrop for the scene. Image Credit: NASA #nasa #satellite #space #nasa #iss #spacestation #cubesat #exp38; -
Movie of Curiosity's View Backwards While Crossing Dune - The series of nine images making up this animation were taken by the rear Hazard-Avoidance Camera (rear Hazcam) on NASA's Curiosity Mars rover as the rover drove over a dune spanning "Dingo Gap" on Mars. The Hazcam, mounted low on the vehicle's chassis, provides a wide-angle view. Curiosity made this 23-foot (7 meter) drive during the 535th Martian day, or sol, of its work on Mars (Feb. 6, 2014). At the start of the drive, the rover's right-front wheel was already at the crest of the 3-foot-tall (1-meter-tall) dune, with the rover still pointed uphill. By the last three images in the series, the rover was headed downhill. The light-toned dome on the right side of the horizon is part of Mount Sharp. This drive was westward. The rover's long-term destination on the lower slope of Mount Sharp is still farther west and south from the rover's current location. Dingo Gap provided an entryway into a valley to the west. The valley appealed to the rover team as a driving route because its terrain includes fewer sharp rocks than alternative routes considered.

Sochi Olympic Park Viewed From the International Space Station - An Expedition 38 crew member aboard the #ISS took this photograph of Sochi Olympic Park at night. Fisht Olympic Stadium and the flame are visible. The station 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.

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.
