Infrared Image of Saturn's Rings - Although it may look to our eyes like other images of the rings, this infrared image of Saturn's rings was taken with a special filter that will only admit light polarized in one direction. Scientists can use these images to learn more about the nature of the particles that make up Saturn's rings. The bright spot in the rings is the "opposition surge" where the Sun-Ring-Spacecraft angle passes through zero degrees. Ring scientists can also use the size and magnitude of this bright spot to learn more about the surface properties of the ring particles. The image was taken with the Cassini spacecraft wide-angle camera on Aug. 18, 2013, using a spectral filter sensitive to wavelengths of near-infrared light centered at 705 nanometers.

Rosetta Spacecraft (Artist's Concept) – The European Space Agency's Rosetta spacecraft, which carries three NASA instruments, is expected to "wake up" on Jan. 20. The Rosetta mission is set to observe a space-bound icy dirt ball from up close -- for months on end. The spacecraft, festooned with 25 instruments between its lander and orbiter (including three from NASA) will monitor comet 67P/Churyumov-Gerasimenko as it makes its nosedive into, and then climb out of, the inner solar system. An artist's view of Rosetta: The spacecraft is covered with dark thermal insulation in order to retain its warmth while venturing into the coldness of the outer solar system, beyond Mars orbit. NASA's contribution includes three of the orbiter's instruments (the Microwave Instrument for Rosetta Orbiter, the Ion and Electron Sensor and an ultraviolet spectrometer called Alice). NASA is also providing part of the electronics package for an instrument called the Double Focusing Mass Spectrometer, which is part of the Swiss-built Rosetta Orbiter Spectrometer for Ion and Neutral Analysis instrument. NASA is also providing U.S. science investigators for selected non-U.S. instruments and is involved in seven of the mission's 25 instruments. NASA's Deep Space Network provides support for ESA's Ground Station Network for spacecraft tracking and navigation.

The first day of March 1780 was a particularly productive night for Charles Messier. Combing the constellation of Leo for additions to his grand astronomical catalog, he struck on not one, but two, new objects. One of those objects is seen here in an image from the Hubble Space Telescope: Messier 65. "Nebula discovered in Leo: It is very faint and contains no star," he jotted down in his notebook. But he was wrong — as we now know, Messier 65 is a spiral galaxy containing billions upon billions of stars. All Messier saw was a faint diffuse light, nothing like the fine detail here, so we can forgive his mistake. If he had had access to a telescope like Hubble, he could have spied these stunning, tightly wound purple spiral arms and dark dust lanes, encircling a bright center crammed with stars. Almost exactly 233 years later in March of 2013, one of the stars within Messier 65 went supernova (not seen in this image), rivaling the rest of the entire galaxy in brightness. This, the first Messier supernova of 2013, is now fading, and the serene beauty of M65 is returning.

Stellar Genesis in the Southern Pinwheel - The full beauty of nearby barred spiral galaxy M83 is unveiled in all of its glory in this Hubble Space Telescope mosaic image. The vibrant magentas and blues reveal the galaxy is ablaze with star formation. The galaxy, also known as the Southern Pinwheel, lies 15 million light-years away in the constellation Hydra. The Hubble photograph captures thousands of star clusters, hundreds of thousands of individual stars, and "ghosts" of dead stars called supernova remnants. The galactic panorama unveils a tapestry of the drama of stellar birth and death spread across 50,000 of light years.

Engineers and safety specialists from NASA and Space Exploration Technologies (SpaceX) gathered in Morro Bay, Calif., in late December to demonstrate how the company's Dragon spacecraft's parachute system would function in the event of an emergency on the launch pad or during ascent. The test was part of an optional milestone under NASA's Commercial Crew Integrated Capability (CCiCap) initiative and approved by the agency in August. Through the Commercial Crew Program, SpaceX is one of NASA's commercial partners working to develop a new generation of U.S. spacecraft and rockets capable of transporting humans to and from low-Earth orbit from American soil. NASA intends to use such commercial systems to fly U.S. astronauts to and from the International Space Station. The 12,000-pound test craft was lifted 8,000 feet above sea level by an Erickson Sky Crane helicopter and flown over the Pacific Ocean. Following Dragon's release, two drogue parachutes were released from the top of the spacecraft to slow its decent, before the three main parachutes deployed. The craft splashed down and was quickly recovered by the Sky Crane and carried back to shore.

Congratulations to the Morpheus Lander team on yesterday's free flight test. The 57-second test began at 1:15 p.m. EST on Thursday with the Morpheus lander launching from the ground over a flame trench and ascending approximately 187 feet, nearly doubling the target ascent velocity from the last test. Morpheus then flew forward, covering about 154 feet in 20 seconds before descending and landing on a dedicated pad inside the automated landing and hazard avoidance technology (ALHAT) hazard field. Morpheus landed within 11 inches of its target. Project Morpheus tests NASA's automated landing and hazard avoidance technology and an engine that runs on liquid oxygen and methane, or "green" propellants. These new capabilities could be used in future efforts to deliver cargo to planetary surfaces. Morpheus and ALHAT are examples of the partnerships that exist within the agency since seven of the 10 NASA centers have contributed time, energy and resources to both.

NASA Center Renamed in Honor of Neil A. Armstrong - President Barack Obama has signed HR 667, the congressional resolution that redesignates NASA's Hugh L. Dryden Flight Research Center as the Neil A. Armstrong Flight Research Center, into law. Armstrong was a naval aviator from 1949 to 1952. During the Korean War he flew 78 combat missions. In 1955 he joined the National Advisory Committee for Aeronautics (NACA), NASA's predecessor, as a research pilot at Lewis Laboratory in Cleveland. He later transferred to NACA's High Speed Flight Research Station at Edwards AFB, Calif., later named NASA's Dryden Flight Research Center. As a research project test pilot over the course of seven years at the center from 1955 through 1962, he was in the forefront of the development of many high-speed aircraft. This photograph shows Neil Armstrong next to the X-15 rocket-powered aircraft after a research flight. He was one of only 12 pilots to fly the hypersonic X-15 as well as the first of 12 men to later walk on the moon. In all, he flew more than 200 different types of aircraft.

A wildfire started and spread quickly in the foothills northeast of Los Angeles on Jan. 16, 2014. The plume of smoke blanketed much of the metropolitan area and prompted air quality warnings across the region. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra and Aqua satellites captured these images of the Colby fire in Angeles National Forest just before (top) and just after noon on January 16. The morning image is clearer because the scene was centered under the satellite, while the afternoon image is fuzzy because the satellite was observing from an angle. According to InciWeb, the fire started around 6 a.m. Pacific Time on January 16 near the Glendora Mountain Road and the Colby Truck Trail in Glendora, California. As of 3 p.m. local time, nearly 500 firefighters were working the fire, which had destroyed 1,700 acres and at least two homes.

NASA is inviting people around the world to submit their names to be etched on a microchip aboard a spacecraft headed to the asteroid Bennu in 2016. The "Messages to Bennu!" microchip will travel to the asteroid aboard the agency's Origins-Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) spacecraft. The robotic mission will spend more than two years at the 1,760-foot (500-meter)-wide asteroid. The spacecraft will collect a sample of Bennu's surface and return it to Earth in a sample return capsule. Those wishing to participate in "Messages to Bennu!" should submit their name online no later than Sept. 30 at: http://planetary.org/bennu Image credit: NASA/Goddard/Chris Meaney #bennu #asteroid #asteroid #asteroidbennu #osirisrex #nasa #space #spacecraft #name #sendyournametospace;

Vigorous mixing in the air above large cracks in Arctic sea ice that expose seawater to cold polar air pumps atmospheric mercury down to the surface, finds a NASA field campaign. This process can lead to more of the toxic pollutant entering the food chain, where it can negatively affect the health of fish and animals who eat them, including humans. Scientists measured increased concentrations of mercury near ground level after sea ice off the coast of Barrow, Alaska, cracked, creating open seawater channels called leads. The researchers were in the Arctic for the NASA-led Bromine, Ozone, and Mercury Experiment (BROMEX) in 2012. The mercury-pumping reaction takes place because open water in a lead is much warmer than the air above it, according to study lead author Chris Moore of the Desert Research Institute, Reno, Nev in a paper reporting the discovery published in Nature on Jan. 15. Because of that temperature difference, the air above the lead churns like the air above a boiling pot. Almost all of the mercury in the Arctic atmosphere is transported there in gaseous form from sources in areas farther south. Scientists have long known that mercury in the air near ground level undergoes complex chemical reactions that deposit the element on the surface. Once the mercury is completely removed from the air, these reactions stop. However, this newly discovered mixing triggered by leads in the sea ice forces down additional mercury to restart and sustain the reactions.

Spitzer's Orion - Few cosmic vistas excite the imagination like the Orion Nebula, an immense stellar nursery some 1,500 light-years away. This stunning false-color view spans about 40 light-years across the region, constructed using infrared data from the Spitzer Space Telescope. Compared to its visual wavelength appearance, the brightest portion of the nebula is likewise centered on Orion's young, massive, hot stars, known as the Trapezium Cluster. But the infrared image also detects the nebula's many protostars, still in the process of formation, seen here in red hues. In fact, red spots along the dark dusty filament to the left of the bright cluster include the protostar cataloged as HOPS 68, recently found to have crystals of the silicate mineral olivine within its protostellar envelope.
