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 on Mars
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 : 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


Jupiter
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
for the public to peruse and process into image products.

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

 Elliptical crater in Terra Sabaea 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 : Send in the Clouds .- Enviar en las nubes............del Titán.....

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

Titan
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.

NASA : Juno on Jupiter's Doorstep .- Juno a las puertas de Júpiter..............

http://www.nasa.gov/image-feature/juno-on-jupiters-doorstep

Jupiter and four moons photographed from a distance
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 : Chasma Boreale and North Polar Ice Cap of Mars .- Chasma Boreal y el Norte de casquete glaciar polar de Marte

http://www.nasa.gov/image-feature/chasma-boreale-and-the-north-polar-ice-cap

3-D perspective of Mars
Mars has bright polar caps of ice that are easily visible from telescopes on Earth. A seasonal cover of carbon-dioxide ice and snow is observed to advance and retreat over the poles during the Martian year. Scientists using radar data from NASA's Mars Reconnaissance Orbiter (MRO) have found a record of the most recent Martian ice age recorded in the planet's north polar ice cap.
 
This image is a simulated 3-D perspective view of Chasma Boreale, a canyon that reaches 570 kilometers (350 miles) into the north polar cap. It was created from image data taken by the THEMIS instrument on NASA's Mars Odyssey spacecraft. Canyon walls rise about 1,400 meters (4,600 feet) above the floor of Chasma Boreale. Where the edge of the ice cap has retreated, sheets of sand are emerging that accumulated during earlier ice-free climatic cycles. Winds blowing off the ice have pushed loose sand into dunes, then driven them down-canyon in a westward direction.

NASA : Up and Over.- Arriba y por encima

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................."
More information.............

Saturn
      
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.

NASA to Provide Coverage of May 9 Mercury Transit of the Sun

NASA is inviting media and viewers around the world to see a relatively rare celestial event, with coverage of the Monday, May 9 transit of the sun by the planet Mercury. Media may view the event at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Agency scientists will be available at the Goddard viewing event for live media interviews from 6 to 11:30 a.m. EDT. To attend, media must contact Michelle Handleman at michelle.z.handleman@nasa.gov. To schedule an interview with a NASA scientist at the event, contact Claire Saravia, claire.g.desaravia@nasa.gov.

Mercury passes between Earth and the sun only about 13 times a century, its last trek taking place in 2006. Due to its diminutive size, viewing this event safely requires a telescope or high-powered binoculars fitted with solar filters made of specially-coated glass or Mylar.

NASA is offering several avenues for the public to view the event without specialized and costly equipment, including images on NASA.gov, a one-hour NASA Television special, and social media coverage.

Mercury will appear as a small black dot as it crosses the edge of the sun and into view at 7:12 a.m. The planet will make a leisurely journey across the face of the sun, reaching mid-point at approximately 10:47 a.m., and exiting the golden disk at 2:42 p.m. The entire 7.5-hour path across the sun will be visible across the Eastern United States – with magnification and proper solar filters – while those in the West can observe the transit in progress after sunrise.
NASA also will stream a live program on NASA TV and the agency’s Facebook page from 10:30 to 11:30 a.m. -- an informal roundtable during which experts representing planetary, heliophysics and astrophysics will discuss the science behind the Mercury transit. Viewers can ask questions via Facebook and Twitter using #AskNASA.

Roundtable participants include:
  • Jim Green, planetary science director at NASA Headquarters in Washington
  • Lika Guhathakurta, heliophysics program scientist at NASA Headquarters
  • Nicky Fox, project scientist for the Solar Probe Plus mission at Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland
  • Doug Hudgins, Exoplanet Exploration Program scientist at NASA Headquarters

Media accreditation now is open for events around the arrival of NASA’s Juno spacecraft at Jupiter on July 4. The spacecraft, which will reveal the story of the formation and evolution of the planet Jupiter, will enter into orbit around the gas giant that evening, five years after leaving Earth.

The event and related news conferences will be carried live on NASA Television and the agency's website. Further details and updates will be announced as they become available.

To cover Juno arrival events at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, media can begin the process of applying for credentials by sending all of the following information to: jplmediacredentials@jpl.nasa.gov.

  • Your name (as spelled on your driver’s license with middle name), title, phone number and work email
  • Country of citizenship
  • If not a U.S. citizen, are you a green card holder?
  • Media outlet name, address, phone number, and website
  • Editor's name, phone number and work email

To allow time for processing and approval, foreign nationals and representatives of foreign media outlets must apply by May 11. U.S. citizens and green card holders representing U.S. media outlets must apply by June 2. For more information about media accreditation, contact Elena Mejia at 818-354-1712 or elena.mejia@jpl.nasa.gov.

Media should confirm they have been credentialed before making travel arrangements. Credentialed media will have access to interview, photo and b-roll opportunities, and media briefings before and after spacecraft orbital insertion. The JPL Juno newsroom will open on June 30.

Juno will make two 53-day elliptical laps around Jupiter, before beginning the mission's science phase. At that point, the spacecraft will begin orbiting the Jovian world every 14 days, from a distance as close as 3,100 miles (5,000 kilometers). It will peer beneath Jupiter's cloud tops to learn about the planet's origins, composition and magnetosphere. Jupiter lies in the harshest radiation environment in our solar system, so this particular spacecraft orbit insertion will mark a new achievement in planetary exploration.

JPL manages the Juno mission for NASA. The principal investigator for the mission is Scott Bolton, of Southwest Research Institute in San Antonio. The Juno mission is part of the New Frontiers Program managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama for the agency’s Science Mission Directorate. Lockheed Martin Space Systems, in Denver, built the spacecraft. JPL is a division of the California Institute of Technology in Pasadena.

NASA's solar-powered Juno spacecraft successfully executed a maneuver to adjust its flight path today, Feb. 3. The maneuver refined the spacecraft’s trajectory, helping set the stage for Juno's arrival at the solar system’s largest planetary inhabitant five months and a day from now.

"This is the first of two trajectory adjustments that fine tune Juno’s orbit around the sun, perfecting our rendezvous with Jupiter on July 4th at 8:18 p.m. PDT [11:18 p.m. EDT]," said Scott Bolton, Juno principal investigator at the Southwest Research Institute in San Antonio.

The maneuver began at 10:38 a.m. PST (1:38 p.m. EST). The Juno spacecraft's thrusters consumed about 1.3 pounds (0.6 kilograms) of fuel during the burn, and changed the spacecraft's speed by 1 foot (0.31 meters), per second. At the time of the maneuver, Juno was about 51 million miles (82 million kilometers) from Jupiter and approximately 425 million miles (684 million kilometers) from Earth. The next trajectory correction maneuver is scheduled for May 31. 

Juno was launched on Aug. 5, 2011. The spacecraft will orbit the Jovian world 33 times, skimming to within 3,100 miles (5,000 kilometers) above the planet's cloud tops every 14 days. During the flybys, Juno will probe beneath the obscuring cloud cover of Jupiter and study its aurorae to learn more about the planet's origins, structure, atmosphere and magnetosphere.

Juno's name comes from Greek and Roman mythology. The god Jupiter drew a veil of clouds around himself to hide his mischief, and his wife -- the goddess Juno -- was able to peer through the clouds and reveal Jupiter's true nature.

NASA's Jet Propulsion Laboratory, Pasadena, California, manages the Juno mission for the principal investigator, Scott Bolton, of Southwest Research Institute in San Antonio. Juno is part of NASA's New Frontiers Program, which is managed at NASA's Marshall Space Flight Center in Huntsville, Alabama, for NASA's Science Mission Directorate.

NASA : Haze Layers Above Pluto .- Las capas de neblina encima de Plutón

Hola amigos: A VUELO DE UN QUINDE EL BLOG., Esta imagen de capas de neblina por encima del miembro de Plutón fue tomada por la cámara de imagen visible Ralph / multiespectral (CIVM) en la nave espacial New Horizons de la NASA. se observan alrededor de 20 capas de neblina; las capas se han encontrado para extender típicamente horizontalmente sobre cientos de kilómetros, pero no son estrictamente paralelos a la superficie. Por ejemplo, los científicos señalan una capa de neblina de unos 3 millas (5 kilómetros) sobre la superficie (zona inferior izquierda de la imagen), que desciende a la superficie de la derecha.
MORE INFORMATION.....

Haze layers over limb of Pluto imaged during flyby
This image of haze layers above Pluto’s limb was taken by the Ralph/Multispectral Visible Imaging Camera (MVIC) on NASA’s New Horizons spacecraft. About 20 haze layers are seen; the layers have been found to typically extend horizontally over hundreds of kilometers, but are not strictly parallel to the surface. For example, scientists note a haze layer about 3 miles (5 kilometers) above the surface (lower left area of the image), which descends to the surface at the right.
 
This week, in the journal Science, New Horizons scientists have authored the first comprehensive set of papers describing results from last summer’s Pluto system flyby. Above the surface, scientists discovered Pluto’s atmosphere contains layered hazes, and is both cooler and more compact than expected. This affects how Pluto’s upper atmosphere is lost to space, and how it interacts with the stream of charged particles from the sun known as the solar wind.

Researchers from NASA and other institutions will present science results from the agency’s Mars missions, New Horizons flyby of Pluto, and Dawn mission observations of the dwarf planet Ceres during the 47th Lunar and Planetary Science Conference March 21-25 near Houston.  

The conference will take place at the Woodlands Waterway Marriott Hotel and Convention Center at 1601 Lake Robbins Drive in The Woodlands, Texas. Briefing times (all CDT) are as follows:
  • Noon, Monday, March 21 -- New Horizons mission media briefing  
  • Noon, Tuesday, March 22 -- Dawn mission media briefing
  • 7:30 p.m., Tuesday, March 22 -- Alan Stern, principal investigator for the New Horizons mission, will deliver a lecture, “The Exploration of Pluto.” This lecture is free and open to the public.

Media may register to attend. For information including links to the program, media advisories and contact information, visit:


Briefings will be live streamed and/or archived online. The schedule is available at:


In July 2015, NASA’s New Horizons became the first spacecraft to fly past Pluto, observing a wide range of surface expressions and geology that raise fundamental questions about how small planets can have active processes billions of years after they formed.

Results from the first year of Dawn’s exploration of Ceres mission will be presented, including new insights about the dwarf planet’s surface and composition.  

The science presentations at the conference will include what researchers have learned from recent investigation by NASA's Curiosity rover of an active Martian sand dune and diverse findings from other NASA missions to Mars.

The conference is presented by the Lunar and Planetary Institute (LPI) in Houston. LPI is managed by the Universities Space Research Association (USRA), a national, nonprofit consortium of 105 leading research universities chartered in 1969 by the National Academy of Sciences at the request of NASA. USRA operates programs and institutes focused on research and education in several disciplines engaged in space-related science and engineering.

NASA : Floating Hills on Pluto's Sputnik Planum .- Colinas flotantes en Plutón Sputnik Planum

Hola amigos: A VUELO DE UN QUINDE EL BLOG., Los glaciares de hielo de nitrógeno en Plutón parecen llevar una carga intrigante: numerosas colinas, aisladas que pueden ser fragmentos de hielo de agua desde las tierras altas de los alrededores de Plutón. Estas colinas miden individualmente una a varias millas o kilómetros de diámetro, de acuerdo con las imágenes y los datos de la misión New Horizons de la NASA.

Pluto Terrain
The nitrogen ice glaciers on Pluto appear to carry an intriguing cargo: numerous, isolated hills that may be fragments of water ice from Pluto’s surrounding uplands. These hills individually measure one to several miles or kilometers across, according to images and data from NASA’s New Horizons mission.
 
The hills, which are in the vast ice plain informally named Sputnik Planum within Pluto’s ‘heart,’ are likely miniature versions of the larger, jumbled mountains on Sputnik Planum’s western border. They are yet another example of Pluto’s fascinating and abundant geological activity.

NASA : Pluto’s Wright Mons in Color .- De Plutón Wright Lunas en color

Hola amigos: A VUELO DE UN QUINDE EL BLOG.,Esta característica, conocida como Wright Mons, fue nombrado de manera informal por el equipo de New Horizons en honor de los hermanos Wright. A unas 90 millas (150 kilómetros) de ancho y 2,5 millas (4 kilómetros) de altura, esta característica es enorme. Si en realidad es un volcán de hielo, como se sospecha, sería la más grande de estas características descubierto en el sistema solar exterior....

highest-resolution color view of one of two potential cryovolcanoes spotted on the surface of Pluto by the New Horizons
Scientists with NASA’s New Horizons mission have assembled this highest-resolution color view of one of two potential cryovolcanoes spotted on the surface of Pluto by the New Horizons spacecraft in July 2015.
 
This feature, known as Wright Mons, was informally named by the New Horizons team in honor of the Wright brothers. At about 90 miles (150 kilometers) across and 2.5 miles (4 kilometers) high, this feature is enormous. If it is in fact an ice volcano, as suspected, it would be the largest such feature discovered in the outer solar system.
Mission scientists are intrigued by the sparse distribution of red material in the image and wonder why it is not more widespread. Also perplexing is that there is only one identified impact crater on Wright Mons itself, telling scientists that the surface (as well as some of the crust underneath) was created relatively recently. This is turn may indicate that Wright Mons was volcanically active late in Pluto’s history.
This composite image includes pictures taken by the New Horizons spacecraft’s Long Range Reconnaissance Imager (LORRI) on July 14, 2015, from a range of about 30,000 miles (48,000 kilometers), showing features as small as 1,500 feet (450 meters) across. Sprinkled across the LORRI mosaic is enhanced color data from the Ralph/Multispectral Visible Imaging Camera (MVIC) gathered about 20 minutes after the LORRI snapshots were taken, from a range of 21,000 miles (34,000 kilometers) and at a resolution of about 2,100 feet (650 meters) per pixel. The entire scene is 140 miles (230 kilometers) across.

NASA : Student-Built Experiment Integrated onto NASA’s OSIRIS-REx Mission .- La Misión NASA Osiris, tiene un experimento estudiante de la piedra integrada....

Hola amigos: A VUELO DE UN QUINDE EL BLOG., The Regolith X-ray Imaging Spectrometer (REXIS), El regolito de rayos X Espectrómetro de Imágenes (REXIS) determinará las abundancias elementales en la superficie del asteroide Bennu, complementando las capacidades de minerales y cartografía química proporcionadas por otros dos instrumentos en la nave espacial.
"Los estudiantes trabajaron muy duro para llegar a este punto", dijo Mike Donnelly, director del proyecto OSIRIS-Rex en el Centro de Vuelo Espacial Goddard de la NASA en Greenbelt, Maryland. "Es un gran logro para desarrollar un instrumento de vuelo y lo han integrado a un nave espacial que dirige a un asteroide ".

A student-built experiment aboard NASA’s Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) mission has been integrated onto the spacecraft.

The Regolith X-ray Imaging Spectrometer (REXIS) will determine elemental abundances on the surface of asteroid Bennu, complementing the mineral and chemical mapping capabilities provided by two other instruments on the spacecraft.

"The students worked incredibly hard to get to this point,” said Mike Donnelly, OSIRIS-REx project manager at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “It is quite an accomplishment to develop a flight instrument and have it integrated to a spacecraft that's headed to an asteroid."

REXIS will observe the solar X-rays and their interaction with the asteroid’s surface material, or regolith. The surface responds to this incoming energy by glowing faintly, or fluorescing, by emitting X-rays. These X-rays have an energy that is uniquely characteristic of the elements. REXIS is a telescope that images this X-ray fluorescence, allowing the production of maps of the different elements present on Bennu's surface.

REXIS brings together students and faculty from Massachusetts Institute of Technology (MIT) and Harvard University, both in Cambridge. After a competitive process REXIS was selected as a student collaboration experiment as part of OSIRIS-REx.
The instrument will involve more than 100 students throughout the mission. Students at Harvard and MIT will perform data analysis as part of their coursework.
“The REXIS instrument has already achieved its primary objective – to train the next generation of scientists and engineers,” said Dante Lauretta, principal investigator for OSIRIS-REx at the University of Arizona, Tucson. “This team should be proud of all they have accomplished. I look forward to seeing the REXIS data from Bennu and using it to learn more about the chemistry of the asteroid surface.”
OSIRIS-REx will be the first U.S. mission to sample an asteroid. After launch in September 2016, the OSIRIS-REx spacecraft will travel to the near-Earth asteroid Bennu and retrieve at least 60 grams (2.1 ounces) of surface material and return it to Earth for study. Scientists expect that Bennu may hold clues to the origin of the solar system and the source of the water and organic molecules that may have made their way to Earth. OSIRIS-REx’s investigation will also inform future efforts to develop a mission to mitigate an asteroid impact on Earth, should one be required.
NASA's Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering and safety and mission assurance for OSIRIS-REx.  Dante Lauretta is the mission's principal investigator at the University of Arizona. Lockheed Martin Space Systems in Denver is building the spacecraft. OSIRIS-REx is the third mission in NASA's New Frontiers Program. NASA's Marshall Space Flight Center in Huntsville, Alabama, manages New Frontiers for the agency's Science Mission Directorate in Washington.
