SLS Avionics System Sees the (First) Light - The modern avionics system that will guide the most powerful rocket ever built saw the light -- the "first light," that is. Hardware, software and operating systems for NASA's Space Launch System (SLS) recently were integrated and powered up for an inaugural run -- referred to as "first light." When completed, SLS will be capable of powering humans and potential science payloads to deep space. It has the greatest capacity of any launch system ever built, minimizing cost and risk of deep space journeys. The Integrated Avionics Test Facilities team provided and installed the structure and simulation capability to model the environments the vehicle will experience during launch. With the avionics hardware units arranged in flight configuration on the structure and with the flight software, the facility will replicate what will actually fly the rocket. From left, Wayne Arrington, Gerald Clayton and Ryan MacKrell, all of The Boeing Company, work on setting up the avionics system in flight configuration in the Systems Integration and Test Facility at NASA's Marshall Space Flight Center.

Frozen Lake Sharpe, South Dakota - The Missouri River rises in the Rocky Mountains of western Montana, and flows generally to the southeast for 3,767 kilometers (2,341 miles) to its confluence with the Mississippi River north of St. Louis, Missouri. It is the longest river in North America. The river does not follow a straight southeasterly course along this distance, but includes many meander bends such as the one in this astronaut photograph from the International Space Station. This particular bend is occupied by Lake Sharpe, an approximately 130 kilometer (80 mile) long reservoir formed behind the Big Bend Dam on the Missouri River near Lower Brule, South Dakota. The lake surface is frozen and covered with snow, presenting a uniform white appearance. As meander bends develop, they tend to assume a distinctive U shape. Over time, the river channel can continue to cut into the ends of the “U,” eventually bringing them so close together that the river then cuts across the gap to achieve a shorter flow path and cut off the meander bend. When this happens and the meander ceases to be part of the active river channel, it may become an oxbow lake. The distance across the narrow neck of land (image lower right) associated with this meander is approximately 1 kilometer (0.62 miles). However, the river flow is controlled by the Big Bend Dam downstream, so the natural process of meander cutoff has been significantly slowed. The image was taken by the space station’s Expedition 38 crew. It has been cropped and enhanced to improve contrast, and lens artifacts have been removed.

Astronauts aboard the International Space Station Sunday used a robotic arm to capture and attach the Cygnus supply spacecraft, which carried dozens of new science experiments from across the country and the world to the orbiting laboratory. The arrival capped the first successful contracted cargo delivery by Orbital Sciences Corp. of Dulles, Va., for NASA. Astronaut Mike Hopkins of NASA grappled the spacecraft at 6:08 a.m. EST and Koichi Wakata of the Japan Aerospace Exploration Agency attached Cygnus to the space station's Harmony Node at 8:05 a.m.The Expedition 38 crew members aboard the station will begin unloading the 2,780 pounds (1,261 kilograms) of supplies aboard Cygnus following hatch opening which is currently on the crew’s timeline for Monday. The cargo is comprised of vital science experiments, crew provisions, spare parts and other hardware. This includes 23 student-designed science experiments. One newly arrived investigation will study the decreased effectiveness of antibiotics during spaceflight. Another will examine how different fuel samples burn in microgravity, which could inform future design for spacecraft materials. Orbital's Cygnus was launched on the company's Antares rocket Thursday from the Mid-Atlantic Regional Spaceport Pad 0A at NASA’s Wallops Flight Facility in Virginia. Cygnus will remain attached to Harmony until a planned unberthing in February sends the spacecraft toward a destructive re-entry in Earth's atmosphere.

Back in November, the team behind NASA's James Webb Space Telescope engineering test unit move a primary mirror segment in a protective case, returning it to the cleanroom at NASA Goddard after undergoing some tests at our new Calibration, Integration, and Alignment Facility. The James Webb Space Telescope will be a large infrared telescope with a 6.5-meter primary mirror. The project is working to a 2018 launch date. The Webb will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It will study every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

Hubble Sees a Star Set to Explode: Floating at the center of this new Hubble image is a lidless purple eye, staring back at us through space. This ethereal object, known officially as [SBW2007] 1 but sometimes nicknamed SBW1, is a nebula with a giant star at its center. The star was originally twenty times more massive than our sun, and is now encased in a swirling ring of purple gas, the remains of the distant era when it cast off its outer layers via violent pulsations and winds. But the star is not just any star; scientists say that it is destined to go supernova. Twenty-six years ago, another star with striking similarities went supernova — SN 1987A. Early Hubble images of SN 1987A show eerie similarities to SBW1. Both stars had identical rings of the same size and age, which were travelling at similar speeds; both were located in similar HII regions; and they had the same brightness. In this way SBW1 is a snapshot of SN1987a's appearance before it exploded, and unsurprisingly, astronomers love studying them together. At a distance of more than 20 000 light-years it will be safe to watch when the supernova goes off. If we are very lucky it may happen in our own lifetimes.

Can you see the shape of a hand in this new X-ray image? The hand might look like an X-ray from the doctor's office, but it is actually a cloud of material ejected from a star that exploded. The new 'Hand' image shows a nebula 17,000 light-years away, powered by a dead, spinning star called PSR B1509-58, or B1509 for short. The dead star, called a pulsar, is the leftover core of a star that exploded in a supernova. The pulsar is only about 19 kilometers (12 miles) in diameter but packs a big punch: it is spinning around nearly seven times every second, spewing particles into material that was upheaved during the star's violent death. These particles are interacting with magnetic fields around the ejected material, causing it to glow with X-rays. The result is a cloud that, in previous images, looked like an open hand. One of the big mysteries of this object, called a pulsar wind nebula, is whether the pulsar's particles are interacting with the material in a specific way to make it appear as a hand, or if the material is in fact shaped like a hand.

NASA's Curiosity Mars rover and tracks left by its driving appear in this portion of a Dec. 11, 2013, observation by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter. The rover is near the lower-left corner of this view. For scale, the two parallel lines of the wheel tracks are about 10 feet (3 meters) apart. Curiosity has been on the move. By the time this image was taken, it had driven about 2.86 miles (4.61 kilometers) since its August 2012 landing in Gale Crater. This view shows where the rover has driven generally southwestward, with some variation to get around obstacles, on its route toward its long-term destination on the lower slopes of Mount Sharp.

NASA's Swift Catches X-ray Action at Milky Way's Center - Recent observations by NASA's Swift spacecraft have provided scientists a unique glimpse into the activity at the center of our galaxy and led to the discovery of a rare celestial entity that may help them test predictions of Albert Einstein's theory of general relativity. This week, at the annual meeting of the American Astronomical Society in National Harbor, Md., scientists presented their research into images captured by Swift, explaining how these images will help decipher the physical nature of X-ray flares and enabled their discovery of a rare subclass of neutron star. Swift's seven-year campaign to monitor the center of the Milky Way has doubled the number of images available to scientists of bright X-ray flares occurring at the galaxy's central black hole, dubbed Sagittarius A* (Sgr A*). Sgr A* sits in the center of the Milky Way's innermost region, 26,000 light-years away in the direction of the constellation Sagittarius. Its mass is at least 4 million times that of the sun. Despite its considerable size, it is not nearly as bright as it could be if it was more active, according to one expert. This X-ray image of the galactic center merges Swift XRT observations through 2013. Sgr A* is at center. Low-energy X-rays (300 to 1,500 electron volts) are shown in red, medium-energy (1,500 to 3,000 eV) in green, and high-energy (3,000 to 10,000 eV) in blue. The total exposure time is 12.6 days.

Sun Unleashes First X-class Flare of 2014, Delaying Rocket Launch - The sun emitted a significant solar flare peaking at 1:32 p.m. EST on Jan.7, 2014. This is the first significant flare of 2014, and follows on the heels of mid-level flare earlier in the day. Each flare was centered over a different area of a large sunspot group currently situated at the center of the sun, about half way through its 14-day journey across the front of the disk along with the rotation of the sun. Early this morning, Orbital Sciences Corp. decided to scrub today’s launch attempt of the Antares rocket and the Cygnus cargo spacecraft on the company’s first resupply mission to the International Space Station due to an unusually high level of space radiation that exceeded constraints imposed on Antares. The solar flux activity resulted in an increasing level of radiation beyond what the Antares engineering team monitored earlier in the day. At Mission Control in Houston, the flight control team reported that the ISS crew is not affected by this solar event and does not require any special precautionary measures. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel. This disrupts the radio signals for as long as the flare is ongoing, anywhere from minutes to hours. This pictures combines two images from NASA's Solar Dynamics Observatory captured on Jan. 7, 2013.

'Twas the night before launch… An Orbital Sciences Corporation Antares rocket is seen on launch Pad-0A at NASA's Wallops Flight Facility on the evening of Tuesday, Jan. 7, 2014 in advance of a planned Wednesday, Jan. 8th, 1:32 p.m. EST launch. The Antares will launch a Cygnus spacecraft on a cargo resupply mission to the International Space Station. The Orbital-1 mission is Orbital Sciences' first contracted cargo delivery flight to the space station for NASA. Among the cargo aboard Cygnus set to launch to the space station are science experiments, crew provisions, spare parts and other hardware. There is a 95 percent chance of favorable weather at the time of launch. High, thick clouds are the primary concern for a weather violation. If needed, multiple back-up launch opportunities are available through Jan. 12. Live launch coverage on Jan. 8 will be carried live on NASA TV and the agency's website at www.nasa.gov/ntv beginning at 1:00 p.m. EST (18:00 UCT).

This long-exposure Hubble Space Telescope image of massive galaxy cluster Abell 2744 (foreground) is the deepest ever made of any cluster of galaxies. It shows some of the faintest and youngest galaxies ever detected in space. Abell 2744 is a massive galaxy cluster located in the constellation Sculptor. The immense gravity in Abell 2744 is being used as a lens to warp space and brighten and magnify images of more distant background galaxies. The more distant galaxies appear as they did longer than 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. NASA's Hubble Space Telescope is providing a new perspective on the remote universe, including new views of young and distant galaxies bursting with stars. Scientists described the findings Tuesday in a news conference sponsored by the American Astronomical Society (AAS).

NEOWISE's New Find - The three red dots in this composite picture indicate the location of the first new near-Earth asteroid seen by NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) since the spacecraft came out of hibernation in December 2013. The asteroid, called 2013 YP139, is the first of hundreds of space-rock discoveries expected during its renewed mission. The inset shows a zoomed-in view of one of the detections of 2013 YP139. 2013 YP139 was discovered by NEOWISE on Dec. 29, 2013. The mission's sophisticated software picked out the moving object against a background of stationary stars. Near-Earth objects are asteroids and comets with orbits that come close to Earth's path around the sun. 2013 YP139, is currently about 27 million miles (43 million kilometers) from Earth. Based on its infrared brightness, scientists estimate it to be approximately 0.4 miles (650 meters) in diameter and extremely dark. Because NEOWISE is an infrared telescope, it senses heat from asteroids. 2013 YP139 is as dark as a piece of coal, and it glows brightly at infrared wavelengths. The shortest infrared wavelength, 3.4 microns, is color-coded blue, and the longer wavelength, 4.6 microns, is color-coded red. The asteroid appears as a string of red dots because it is much cooler than the stars. Stars are thousands of degrees, but the asteroid is close to room temperature, so it is red in these images. While asteroid 2013 YP139 orbits the sun in an elliptical orbit nearly in the plane of our solar system and is classified as a potentially hazardous asteroid, it is not likely to approach within Earth's vicinity anytime over the next 100 years. However, the asteroid’s future motion can bring it within about 300,000 miles (490,000 kilometers) of Earth’s orbit, so its long-term motion will be closely monitored.

Stormy Stars? This Just In: Storms Expected on Brown Dwarfs - This artist's concept shows what the weather might look like on cool star-like bodies known as brown dwarfs. These giant balls of gas start out life like stars, but lack the mass to sustain nuclear fusion at their cores, and instead, fade and cool with time. New research from NASA's Spitzer Space Telescope suggests that most brown dwarfs are racked with colossal storms akin to Jupiter's famous "Great Red Spot." These storms may be marked by fierce winds, and possibly lightning. The turbulent clouds might also rain down molten iron, hot sand or salts -- materials thought to make up the cloud layers of brown dwarfs.

Polar Vortex Enters Northern U.S. - The polar vortex is a whirling and persistent large area of low pressure, found typically over both North and South poles. The northern polar vortex was pushing southward over western Wisconsin and eastern Minnesota on Monday, Jan. 6, 2014, and was bringing frigid temperatures to half of the continental United States. It is expected to move northward back over Canada toward the end of the week. This image was captured by NOAA's GOES-East satellite on Jan. 6, 2014, at 11:01 a.m. EST (1601 UTC). A frontal system that brought rain to the coast is draped from north to south along the U.S. East Coast. Behind the front lies the clearer skies bitter cold air associated with the polar vortex. The image also revealed snow on the ground in Minnesota, Wisconsin, Illinois, Indiana, Ohio, Michigan, Iowa and Missouri, stretching into the Great Plains. Clouds over Texas are associated with a low pressure system centered over western Oklahoma that is part of the cold front connected to the movement of the polar vortex. The GOES image was created at NASA's GOES Project, located at NASA's Goddard Space Flight Center in Greenbelt, Md. Both the northern and southern polar vortexes are located in the middle and upper troposphere (lowest level of the atmosphere) and the stratosphere (next level up in the atmosphere). The polar vortex is a winter phenomenon. It develops and strengthens in its respective hemispheres’ winters as the sun sets over the polar region and temperatures cool. They weaken in the summer. In the Northern Hemisphere, they circulate in a counterclockwise direction, so the vortex sitting over western Wisconsin is sweeping in cold Arctic air around it.

NASA's Fermi Makes First Gamma-ray Study of a Gravitational Lens - An international team of astronomers, using NASA's Fermi observatory, has made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source. This accomplishment opens new avenues for research, including a novel way to probe emission regions near supermassive black holes. It may even be possible to find other gravitational lenses with data from the Fermi Gamma-ray Space Telescope. Fermi detected a series of bright gamma-ray flares from a source known as B0218+357, located 4.35 billion light-years from Earth in the direction of a constellation called Triangulum. These powerful flares, in a known gravitational lens system, provided the key to making the lens measurement. Astronomers classify B0218+357 as a blazar -- a type of active galaxy noted for its intense emissions and unpredictable behavior. At the blazar's heart is a supersized black hole with a mass millions to billions of times that of the sun. As matter spirals toward the black hole, some of it blasts outward as jets of particles traveling near the speed of light in opposite directions. This Hubble image of gravitational lens B0218+357 reveals two bright sources separated by about a third of an arcsecond, each an image of the background blazar. Spiral arms belonging to the lensing galaxy also can be seen. B0218+357 boasts the smallest separation of lensed images currently known.
