1 Day until the launch of the next element in the communications network that links NASA's ground controllers to orbiting spacecraft. TDRS-L will become the 11th member of the Tracking and Data Relay Satellite System orbiting Earth following its launch from Cape Canaveral Air Force Station in Florida aboard a United Launch Alliance Atlas V rocket. Liftoff is scheduled for Jan. 23 during a launch window that opens at 9:05 p.m. EST. The constellation of satellites orbiting Earth at 22,300 miles revolutionized communications for the nation's space agency by allowing nearly continuous transmission of information during a mission. Before the TDRS network was established, NASA relied on a patchwork of ground stations based around the world to stitch together coverage zones. Astronauts and Earth-orbiting scientific spacecraft would relay messages only when they passed over or near one of the ground stations. The TDRS-L will ride into space on an Atlas V booster and Centaur upper stage, a combination that has become a workhorse for the agency's recent missions. The Centaur, which takes over after the Atlas V booster's stage has exhausted its fuel, will place the TDRS on a path to reach its 22,300-mi Image credit: NASA #roadsign #countdown #321launch #launch #tdrs #nasa #nasakennedy #centaur #atlasv #mars #sign #streetsign #ula #space; -
Dwarf Planet Ceres (Artist's Impression)- Ceres is located in the main asteroid belt, between the orbits of Mars and Jupiter, as illustrated in this artist's conception. Observations by the Herschel space observatory between 2011 and 2013 find that the dwarf planet has a thin water vapor atmosphere. This is the first unambiguous detection of water vapor around an object in the asteroid belt. Herschel is a European Space Agency mission, with science instruments provided by consortia of European institutes and with important participation by NASA. While the observatory stopped making science observations in April 2013, after running out of liquid coolant, as expected, scientists continue to analyze its data.

Volcanic Smog and Sunglint in the Vanuatu Archipelago- The archipelago is a collection of volcanic islands about 1,800 kilometers (1,100 miles) northeast of Australia. Two of the islands, Gaua and Ambrym, frequently vent sulfurous gases. On Jan. 7, 2014 NASA's Aqua satellite passed over Vanuatu, allowing the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard to capture this true-color image. A broad plume of volcanic vog and ash rises from Ambrym and spreads across the South Pacific. Vog is a combination of “volcanic” and “smog”, and is formed when gases from a volcano react with sunlight, oxygen and moisture. The vog appears as a light blue-gray plume which arcs from the volcanic island both to the northwest and to the northeast. In the northeast, the vog crosses a mirror-like swath of silver-gray which runs from north to south. That swath is not volcanic in origin, but is an artifact called “sunglint” – the reflection of the sun off the ocean in a satellite image.

A fresh apple floating freely near a window in the Cupola of the International Space Station is featured in this image photographed by an Expedition 38 crew member. Attached to the Harmony node, the Orbital Sciences Corp. Cygnus commercial cargo craft, which brought the fresh fruit, is visible at center. The bright sun, Earth's horizon and the blackness of space provide the backdrop for the scene. The expansive International Space Station is a working laboratory orbiting 260 miles above the Earth, traveling at 17,500 mph, and is home to an international crew. It is the most complex scientific and technological endeavor ever undertaken. As a research outpost, the station is a test bed for future technologies and a research laboratory for new, advanced industrial materials, communications technology, medical research and much more.

Satellite View of the Central and Eastern U.S. in the Deep Freeze: This NOAA GOES satellite image from January 21 at 1601 UTC/11:01 a.m. EST shows a snow-covered Mid-west behind the clouds associated with the cold front that is expected to bring snowfall from Virginia to Maine. The GOES image was created at NASA/NOAA's GOES Project at NASA's Goddard Space Flight Center in Greenbelt, Md. At the NASA/NOAA's GOES Project, the GOES data (clouds) were laid down as "primer" over the land and ocean areas, which are derived from Moderate Resolution Imaging Spectroradiometer or MODIS instrument data. MODIS is an instrument that flies aboard NASA's Aqua and Terra satellites. In the image, the colder, higher clouds appear whiter and brighter.

This before-and-after pair of images of the same patch of ground in front of NASA's Mars Exploration Rover Opportunity 13 days apart documents the arrival of a bright rock onto the scene. The rover had completed a short drive just before taking the second image, and one of its wheels likely knocked the rock -- dubbed "Pinnacle Island" -- to this position. The rock is about the size of a doughnut. The images are from Opportunity's panoramic camera (Pancam). The one on the left is from 3,528th Martian day, or sol, of the rover's work on Mars (Dec. 26, 2013). The one on the right, with the newly arrived rock, is from Sol 3540 (Jan. 8, 2014). Much of the rock is bright-toned, nearly white. A portion is deep red in color. Pinnacle Island may have been flipped upside down when a wheel dislodged it, providing an unusual circumstance for examining the underside of a Martian rock. The site is on "Murray Ridge," a section of the rim of Endeavour Crater where Opportunity is working on north-facing slopes during the rover's sixth Martian winter.

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.
