NASA : A Mass of Viscous Flow Features .- Características de una masa de viscosidad

https://www.nasa.gov/image-feature/jpl/pia21554/a-mass-of-viscous-flow-features

Viscous, lobate flow features are commonly found at the bases of slopes in the mid-latitudes of Mars, and are often associated with gullies.

These features are bound by ridges that resemble terrestrial moraines, suggesting that these deposits are ice-rich, or may have been ice-rich in the past. The source of the ice is unclear, but there is some thought that it is deposited from the atmosphere during periods of high obliquity, also known as axial tilt.

The flow features in this image are particularly massive and the bounding scarps appear very high standing and are layered as well. Take a look at the stereo anaglyph for a 3D view.

The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. [The original image scale is 25.9 centimeters (10.2 inches) per pixel (with 1 x 1 binning); objects on the order of 82 centimeters (32.2 inches) across are resolved.] North is up.

This is a stereo pair with ESP_048979_1330.

NASA : Looking Back: Dr. George Carruthers and Apollo 16 Far Ultraviolet Camera/Spectrograph .- Mirando hacia atrás: Dr. George Carruthers y la lejana Cámara ultravioleta / Espectrógrafo del Apollo 16 ...............

https://www.nasa.gov/image-feature/looking-back-dr-george-carruthers-and-apollo-16-far-ultraviolet-cameraspectrograph

Dr. George Carruthers, right, and William Conway, a project manager at the Naval Research Institute, examine the gold-plated ultraviolet camera/spectrograph, the first moon-based observatory that Carruthers developed for the Apollo 16 mission. Working for the Naval Research Laboratory, Carruthers had three years earlier received a patent for a Far Ultraviolet Electrographic Camera, which obtained images in electromagnetic radiation in short wavelengths.

Apollo 16 astronauts placed the observatory on the moon in April 1972, where it sits today on the moon’s Descartes highland region, in the shadow of the lunar module Orion. Asked to explain highlights of the instrument's findings for a general audience, Dr. Carruthers said "the most immediately obvious and spectacular results were really for the Earth observations, because this was the first time that the Earth had been photographed from a distance in ultraviolet light, so that you could see the full extent of the hydrogen atmosphere, the polar auroris and what we call the tropical airglow belt."

Dr. Carruthers made the first detection of molecular hydrogen in space, in 1970, using a sounding rocket. He developed a rocket instrument that obtained an ultraviolet image of Comet Halley, and an instrument with two cameras, with different far-UV wavelength sensitivities, used on the STS-39 space shuttle mission in 1991. He has worked on UV imaging of Earth’s polar auroras and of the faint photochemical luminescence found in the upper atmosphere, with an instrument, Global Imaging Monitor of the Ionosphere (GIMI), on a Department of Defense satellite, the Advanced Research and Global Observation Satellite (ARGOS), launched in 1999. In 2012, he was awarded the National Medal of Technology and Innovation, the nation's highest honor for technology achievement.

NASA : Juno’s Close Look at a Little Red Spot ,. La mirada cercana de Juno en una pequeña mancha roja

https://www.nasa.gov/image-feature/jpl/pia21378/juno-s-close-look-at-a-little-red-spot

The JunoCam imager on NASA’s Juno spacecraft snapped this shot of Jupiter’s northern latitudes on Dec. 11, 2016 at 8:47 a.m. PST (11:47 a.m. EST), as the spacecraft performed a close flyby of the gas giant planet. The spacecraft was at an altitude of 10,300 miles (16,600 kilometers) above Jupiter’s cloud tops. 

This stunning view of the high north temperate latitudes fortuitously shows NN-LRS-1, a giant storm known as a Little Red Spot (lower left). This storm is the third largest anticyclonic reddish oval on the planet, which Earth-based observers have tracked for the last 23 years. An anticyclone is a weather phenomenon with large-scale circulation of winds around a central region of high atmospheric pressure. They rotate clockwise in the northern hemisphere, and counterclockwise in the southern hemisphere. This Little Red Spot shows very little color, just a pale brown smudge in the center. The color is very similar to the surroundings, making it difficult to see as it blends in with the clouds nearby. Citizen scientists Gerald Eichstaedt and John Rogers processed the image and drafted the caption.

JunoCam's raw images are available at

www.missionjuno.swri.edu/junocam

for the public to peruse and process into image products.

JPL manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio.

NASA : New Weather Satellite Sends First Images of Earth .- Nuevo satélite meteorológico envía las primeras imágenes de la Tierra

https://www.nasa.gov/image-feature/new-weather-satellite-sends-first-images-of-earth

The release of the first images today from NOAA’s newest satellite, GOES-16, is the latest step in a new age of weather satellites. This composite color full-disk visible image is from 1:07 p.m. EDT on Jan. 15, 2017, and was created using several of the 16 spectral channels available on the GOES-16 Advanced Baseline Imager (ABI) instrument. The image shows North and South America and the surrounding oceans. GOES-16 observes Earth from an equatorial view approximately 22,300 miles high, creating full disk images like these, extending from the coast of West Africa, to Guam, and everything in between.

 

GOES-16, formerly known as GOES-R, is the first spacecraft in a new series of NASA-built advanced geostationary weather satellites. NASA successfully launched the satellite at 6:42 p.m. EST on Nov. 19, 2016, from Cape Canaveral Air Force Station in Florida. NOAA manages the GOES-R Series Program through an integrated NOAA-NASA office. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, oversees the acquisition of the GOES-R series spacecraft and instruments.

NASA : Well-Preserved Impact Ejecta on Mars .- Efectamiento de impacto bien conservado en Marte

https://www.nasa.gov/image-feature/jpl/well-preserved-impact-ejecta-on-mars

This image of a well-preserved unnamed elliptical crater in Terra Sabaea, is illustrative of the complexity of ejecta deposits forming as a by-product of the impact process that shapes much of the surface of Mars.

 

Here we see a portion of the western ejecta deposits emanating from a 10-kilometer impact crater that occurs within the wall of a larger, 60-kilometer-wide crater. In the central part is a lobe-shaped portion of the ejecta blanket from the smaller crater. The crater is elliptical not because of an angled (oblique) impact, but because it occurred on the steep slopes of the wall of a larger crater. This caused it to be truncated along the slope and elongated perpendicular to the slope. As a result, any impact melt from the smaller crater would have preferentially deposited down slope and towards the floor of the larger crater (towards the west).

Within this deposit, we can see fine-scale morphological features in the form of a dense network of small ridges and pits. These crater-related pitted materials are consistent with volatile-rich impact melt-bearing deposits seen in some of the best-preserved craters on Mars (e.g., Zumba, Zunil, etc.). These deposits formed immediately after the impact event, and their discernible presence relate to the preservation state of the crater. This image is an attempt to visualize the complex formation and emplacement history of these enigmatic deposits formed by this elliptical crater and to understand its degradation history.

NASA : Breaking Boundaries in New Engine Designs .- Cómo romper fronteras en nuevos diseños de motores....

https://www.nasa.gov/image-feature/breaking-boundaries-in-new-engine-designs

Back to Gallery

In an effort to improve fuel efficiency, NASA and the aircraft industry are rethinking aircraft design. Inside the 8’ x 6’ wind tunnel at NASA Glenn, engineers recently tested a fan and inlet design, commonly called a propulsor, which could use four to eight percent less fuel than today’s advanced aircraft.

The new propulsor is designed to be embedded in the aircraft’s body, where it would ingest the slower flowing air that normally develops along an aircraft’s surface, called boundary layer, and use it to help propel the aircraft.

The tests showed that the new fan and inlet design could withstand the turbulent boundary layer airflow and increase efficiency. Results of the tests can be applied to cutting-edge aircraft designs that NASA and its partners are pursuing.

NASA : Send in the Clouds .- Enviar en las nubes............del Titán.....

https://www.nasa.gov/image-feature/jpl/send-in-the-clouds

Floating high above the hydrocarbon lakes, wispy clouds have finally started to return to Titan's northern latitudes.

Clouds like these disappeared from Titan's (3,200 miles or 5,150 kilometers across) northern reaches for several years (from about 2010 to 2014). Now they have returned, but in far smaller numbers than expected. Since clouds can quickly appear and disappear, Cassini scientists regularly monitor the large moon, in the hopes of observing cloud activity. They are especially interested in comparing these observations to predictions of how cloud cover should change with Saturn’s seasons. Titan’s clear skies are not what researchers expected.

See PIA18421 for more on the disappearance and return of the clouds. For a movie of the clouds in motion, see PIA21051.

This view looks toward the Saturn-facing side of Titan. North on Titan is up and rotated 3 degrees to the left. The image was taken with the Cassini spacecraft narrow-angle camera on Oct. 29, 2016 using a spectral filter that preferentially admits wavelengths of near-infrared light centered at 938 nanometers.

The view was obtained at a distance of approximately 545,000 miles (878,000 kilometers) from Titan. Image scale is 3 miles (5 kilometers) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.

NASA : James Webb Space Telescope Mirrors Will Piece Together Cosmic Puzzles.- Los espejos del Telescopio Espacial James Webb, Juntos Puzzles Cósmicos

https://www.nasa.gov/image-feature/prototype-capture-system-mock-asteroid-help-simulate-mission-sequence

The primary mirror of NASA's James Webb Space Telescope consisting of 18 hexagonal mirrors looks like a giant puzzle piece standing in the massive clean room of NASA's Goddard Space Flight Center in Greenbelt, Maryland. Appropriately, combined with the rest of the observatory, the mirrors will help piece together puzzles scientists have been trying to solve throughout the cosmos.

Webb's primary mirror will collect light for the observatory in the scientific quest to better understand our solar system and beyond. Using these mirrors and Webb's infrared vision scientists will peer back over 13.5 billion years to see the first stars and galaxies forming out of the darkness of the early universe. Unprecedented infrared sensitivity will help astronomers to compare the faintest, earliest galaxies to today's grand spirals and ellipticals, helping us to understand how galaxies assemble over billions of years. Webb will see behind cosmic dust clouds to see where stars and planetary systems are being born. It will also help reveal information about atmospheres of planets outside our solar system, and perhaps even find signs of the building blocks of life elsewhere in the universe.

The Webb telescope was mounted upright after a "center of curvature" test conducted at Goddard. This initial center of curvature test ensures the integrity and accuracy, and test will be repeated later to verify those same properties after the structure undergoes launch environment testing. In the photo, two technicians stand before the giant primary mirror.

The Webb telescope is an international collaboration between NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA).

NASA : Prototype Capture System, Mock Asteroid Help Simulate Mission Sequence.-

http://www.nasa.gov/image-feature/prototype-capture-system-mock-asteroid-help-simulate-mission-sequence

A prototype of the Asteroid Redirect Mission (ARM) robotic capture module system is tested with a mock asteroid boulder in its clutches at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The robotic portion of ARM is targeted for launch in 2021.

Located in the center’s Robotic Operations Center, the mockup helps engineers understand the intricate operations required to collect a multi-ton boulder from an asteroid’s surface. The hardware involved here includes three space frame legs with foot pads, two seven degrees of freedom arms that have with microspine gripper “hands” to grasp onto the boulder. 

NASA and students from West Virginia University built the asteroid mockup from rock, styrofoam, plywood and an aluminum endoskeleton. The mock boulder arrived in four pieces and was assembled inside the ROC to help visualize the engagement between the prototype system and a potential capture target. 

Inside the ROC, engineers can use industrial robots, a motion-based platform, and customized algorithms to create simulations of space operations for robotic spacecraft. The ROC also allows engineers to simulate robotic satellite servicing operations, fine tuning systems and controllers and optimizing performance factors for future missions when a robotic spacecraft might be deployed to repair or refuel a satellite in orbit.

NASA's Juno spacecraft obtained this color view on June 21, 2016, at a distance of 6.8 million miles (10.9 million kilometers) from Jupiter. Juno will arrive at Jupiter on July 4.

 

As Juno makes its initial approach, the giant planet's four largest moons -- Io, Europa, Ganymede and Callisto -- are visible, and the alternating light and dark bands of the planet's clouds are just beginning to come into view.

 

Juno is approaching over Jupiter's north pole, affording the spacecraft a unique perspective on the Jupiter system. Previous missions that imaged Jupiter on approach saw the system from much lower latitudes, closer to the planet's equator.

 

The scene was captured by the mission's imaging camera, called JunoCam, which is designed to acquire high resolution views of features in Jupiter's atmosphere from very close to the planet.

NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio.

Hola amigos: A VUELO DE UN QUINDE EL BLOG., Con 14 motores eléctricos girar las hélices y todos ellos integrados en un ala de diseño único, la NASA probará nueva tecnología de propulsión utilizando un avión experimental designado ahora el X-57 y apodado: "Maxwell."  Esta concepción artística  X-57 muestra el ala especialmente diseñado de avión y 14 motores eléctricos. los investigadores de la NASA Aeronáutica utilizarán el Maxwell para demostrar que la propulsión eléctrica puede hacer aviones más silenciosos, más eficientes y más respetuosos con el medio ambiente.

More information.........

http://www.nasa.gov/image-feature/nasas-x-57-electric-research-plane

 

“With the return of piloted X-planes to NASA’s research capabilities – which is a key part of our 10-year-long New Aviation Horizons initiative – the general aviation-sized X-57 will take the first step in opening a new era of aviation,” said NASA Administrator Charles Bolden, during his keynote speech Friday in Washington at the American Institute of Aeronautics and Astronautics (AIAA) annual Aviation and Aeronautics Forum and Exposition.

NASA’s aeronautical innovators hope to validate the idea that distributing electric power across a number of motors integrated with an aircraft in this way will result in a five-time reduction in the energy required for a private plane to cruise at 175 mph.

Several other benefits would result as well. “Maxwell” will be powered only by batteries, eliminating carbon emissions and demonstrating how demand would shrink for lead-based aviation fuel still in use by general aviation.

Energy efficiency at cruise altitude using X-57 technology could benefit travelers by reducing flight times, fuel usage, as well as reducing overall operational costs for small aircraft by as much as 40 percent. Typically, to get the best fuel efficiency an airplane has to fly slower than it is able. Electric propulsion essentially eliminates the penalty for cruising at higher speeds.

Finally, as most drivers of hybrid electric cars know, electric motors are more quiet than conventional piston engines. The X-57’s electric propulsion technology is expected to significantly decrease aircraft noise, making it less annoying to the public.

NASA : NASA's OSIRIS-REx Spacecraft Prepared for Mission to an Asteroid.- Nave espacial Osiris-Rex de la NASA preparado para la misión a un asteroide

http://www.nasa.gov/image-feature/nasas-osiris-rex-spacecraft-prepared-for-mission-to-an-asteroid

NASA's OSIRIS-REx spacecraft is revealed after its protective cover is removed inside the Payload Hazardous Servicing Facility at Kennedy Space Center in Florida, on May 21, 2016. The spacecraft traveled from Lockheed Martin's facility near Denver, Colorado to Kennedy to begin processing for its upcoming launch, targeted for Sept. 8 aboard a United Launch Alliance Atlas V rocket. After launch, OSIRIS-REx - which stands for Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer - has an approximately two-year cruise to reach the asteroid Bennu in 2018.

 

Upon arrival, OSIRIS-REx will spend a year flying in close proximity to Bennu, its five instruments imaging the asteroid, documenting its lumpy shape, and surveying its chemical and physical properties. In 2020, OSIRIS-REx will collect a pristine sample of at least two ounces of the asteroid's surface material that will be returned back to Earth in 2023 for analysis. Bennu is part of the debris left over from the formation of the solar system. It is pristine enough to hold clues to solar system's origin and the source of water and organic molecules found on Earth.

Hola mis amigos: A VUELO DE UN QUINDE EL BLOG., Cassini en órbita alrededor de plano de los anillos de Saturno - alrededor del ecuador del planeta - la mayor parte de 2015. Esto permitió una temporada de sobrevuelos de las lunas heladas del planeta, pero no permitió puntos de vista en ángulo de los anillos y los polos del planeta, como éste. Sin embargo, a principios de 2016, la nave espacial comenzó a aumentar su inclinación orbital, subiendo más sobre los polos en preparación para las órbitas finales espectaculares de la misión en 2017.
Esta vista se dirige hacia el lado iluminado de los anillos desde unos 16 grados por encima del plano de los anillos. La imagen fue tomada con la cámara de gran angular de la Cassini el 26 de febrero el año 2016 usando un filtro espectral que preferentemente se admite longitudes de onda de luz casi infrarroja centrada en 752 nanómetros................."

Cassini orbited in Saturn's ring plane -- around the planet's equator -- for most of 2015. This enabled a season of flybys of the planet's icy moons, but did not allow for angled views of the rings and the planet's poles, like this one. But in early 2016, the spacecraft began to increase its orbital inclination, climbing higher over the poles in preparation for the mission's final spectacular orbits in 2017.

This view looks toward the sunlit side of the rings from about 16 degrees above the ring plane. The image was taken with the Cassini spacecraft wide-angle camera on Feb. 26 2016 using a spectral filter which preferentially admits wavelengths of near-infrared light centered at 752 nanometers.

The view was obtained at a distance of approximately 1.7 million miles (2.8 million kilometers) from Saturn. Image scale is 103 miles (165 kilometers) per pixel.

The Cassini mission is a cooperative project of NASA, ESA (the European Space Agency) and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colorado.

NASA : Celebrating Ten Years of NASA's Consolidated Space Communications Program .- Celebrando diez años del programa consolidado Comunicaciones Espaciales de la NASA

This photograph shows NASA’s newest Deep Space Network antenna, Deep Space Station 35 in Canberra, Australia. Together, the Deep Space Network, Near Earth Network and Space Network -- managed and directed by the Space Communications and Navigation (SCaN) program office -- provide communication and tracking services to hundreds of NASA and non-NASA missions.

 

Created on May 16, 2006, Space Communications and Navigation (SCaN) serves as the program office for all of NASA’s space communications activities. SCaN's major accomplishments over the past decade include the first optical communications link from the moon at 622 Mbps; three new Tracking and Data Relay Satellites; construction of an 11-meter Near Earth Network antenna in Alaska; and construction of the 34-meter Deep Space Network (DSN) antenna pictured above. In the future, SCaN will continue to develop leading-edge technologies and enhance communications capabilities, including communications for the Space Launch System and Orion spacecraft through an advanced tracking antenna under construction at NASA's Kennedy Space Center.

NASA : Full of Science, Dragon Spacecraft Undocks for Return to Earth .- Satélite Dragon.lleno de ciencia, se prepara para su retorno a La Tierra....

Hola amigos: A VUELO DE UN QUINDE EL BLOG., la Agencia Espacial NASA, nos informa que la nave espacial Dragón, que es una nave de servicios de llevar abastecimiento retorna a La Tierra llena de datos científicos desde la Estación Espacial Internacional.

European Space Agency astronaut Tim Peake captured this photograph of the SpaceX Dragon cargo spacecraft as it undocked from the International Space Station on May 11, 2016. The spacecraft was released from the station’s robotic arm at 9:19 a.m. EDT. Following a series of departure burns and maneuvers to move beyond the 656-foot (200-meter) “keep out sphere” around the station, Dragon began its return trip to Earth. It is currently scheduled to splashdown in the Pacific Ocean at 2:55 p.m., about 261 miles southwest of Long Beach, California.

The spacecraft will return the final batch of human research samples from former NASA astronaut Scott Kelly’s historic one-year mission. These samples will be analyzed for studies such as Biochemical Profile, Cardio Ox, Fluid Shifts, Microbiome, Salivary Markers and the Twins Study. Additional samples taken on the ground as Kelly continues to support these studies will provide insights relevant for the journey to Mars, as NASA learns more about how the human body adjusts to weightlessness, isolation, radiation and the stress of long-duration spaceflight.

NASA : Hubble Spies the Barred Spiral Galaxy NGC 4394 .- Telescopio Espacial Hubble, espía a la Galaxia NGC 4394

http://www.nasa.gov/image-feature/goddard/2016/hubble-spies-the-barred-spiral-galaxy-ngc-4394

Discovered in 1784 by the German–British astronomer William Herschel, NGC 4394 is a barred spiral galaxy situated about 55 million light-years from Earth. The galaxy lies in the constellation of Coma Berenices (Berenice's Hair) and is considered to be a member of the Virgo Cluster.

NGC 4394 is the archetypal barred spiral galaxy, with bright spiral arms emerging from the ends of a bar that cuts through the galaxy’s central bulge. These arms are peppered with young blue stars, dark filaments of cosmic dust, and bright, fuzzy regions of active star formation. At the center of NGC 4394 lies a region of ionized gas known as a low-ionization nuclear emission-line region (LINER). LINERs are active regions that display a characteristic set of emission lines in their spectra— mostly from weakly ionized atoms of oxygen, nitrogen and sulphur.

Although LINER galaxies are relatively common, it’s still unclear where the energy comes from to ionize the gas. In most cases it is thought to be the influence of a black hole at the center of the galaxy, but it could also be the result of a high level of star formation. In the case of NGC 4394, it is likely that gravitational interaction with a nearby neighbor has caused gas to flow into the galaxy’s central region, providing a new reservoir of material to fuel the black hole or to make new stars.
