NASA : Curiosity's Stars and Stripes .- Barras y estrellas para el Curiosity

 Hola amigos: A VUELO DE UN QUINDE EL BLOG., hemos recibido información de la Agencia Espacial NASA, lo que ellos llaman: Barras y Estrellas para el Curiosity..
NASA nos dice....El medallón circular de la bandera está hecho de aluminio anodizado y mide 2,68 pulgadas (68 milímetros) de diámetro. El medallón fue fijada con pernos a los lugares en los balancines donde el hardware de vuelo una vez fue considerado, pero en última instancia consideró innecesario.

Curiosity's Stars and Stripes
This view of the American flag medallion on NASA's Mars rover Curiosity was taken by the rover's Mars Hand Lens Imager (MAHLI) during the 44th Martian day, or sol, of Curiosity's work on Mars (Sept. 19, 2012). The flag is one of four "mobility logos" placed on the rover's mobility rocker arms.

› View Presidential Plaque

The circular medallion of the flag is made of anodized aluminum and measures 2.68 inches (68 millimeters) in diameter. The medallion was affixed with bolts to locations on the rocker arms where flight hardware was once considered, but ultimately deemed unnecessary.

The other three medallions adorning the rover's rocker arms are the NASA logo, the JPL logo and the Curiosity mission logo.

The main purpose of Curiosity's MAHLI camera is to acquire close-up, high-resolution views of rocks and soil at the rover's Gale Crater field site. The camera is capable of focusing on any target at distances of about 0.8 inch (2.1 centimeters) to infinity, providing versatility for other uses, such as views of the rover itself from different angles.

NASA: NASA’s New Horizons Spacecraft Stays the Course to Pluto .- Nave espacial New Horizons de la NASA Estancias del Curso a Plutón

Hola amigos: A VUELO DE UN QUINDE EN BLOG., hemos recibido información de la Agencia Espacial NASA, sobre las actividades del Satélite NASA’s New Horizons spacecraft, en sus investigaciones sobre el planeta Plutón.
NASA, nos dice: Estas imágenes muestran la diferencia entre dos conjuntos de 48 exposiciones combinadas de 10 segundos con New Horizons 'Long Range Reconocimiento Imager (LORRI) cámara, tomada a las 8:40 GMT y 10:25 GMT el 26 de junio de 2015, de un rango de 21.5 millones de kilómetros (aproximadamente 13 millones de millas) a Plutón. Los satélites  pequeñas conocidas, Nix, Hidra, Kerberos y Styx, son visibles como brillante adyacente y pares oscuras de puntos, debido a su movimiento en los 105 minutos entre los dos conjuntos de imágenes.

Two sets of 48 combined 10-second exposures with New Horizons' Long Range Reconnaissance Imager (LORRI) camera
These images show the difference between two sets of 48 combined 10-second exposures with New Horizons' Long Range Reconnaissance Imager (LORRI) camera, taken at 8:40 UTC and 10:25 UTC on June 26, 2015, from a range of 21.5 million kilometers (approximately 13 million miles) to Pluto. The known small moons, Nix, Hydra, Kerberos and Styx, are visible as adjacent bright and dark pairs of dots, due to their motion in the 105 minutes between the two image sets.
NASA’s New Horizons spacecraft is getting a final “all clear” as it speeds closer to its historic July 14 flyby of Pluto and the dwarf planet’s five moons.
After seven weeks of detailed searches for dust clouds, rings, and other potential hazards, the New Horizons team has decided the spacecraft will remain on its original path through the Pluto system instead of making a late course correction to detour around any hazards. Because New Horizons is traveling at 30,800 mph (49,600 kph), a particle as small as a grain of rice could be lethal.
“We’re breathing a collective sigh of relief knowing that the way appears to be clear,” said Jim Green, director of planetary science at NASA. “The science payoff will be richer as we gather data from the optimal flight path, as opposed to having to conduct observations from one of the back-up trajectories.”
Mission scientists have been using the spacecraft’s most powerful telescopic camera, the Long Range Reconnaissance Imager (LORRI), to look for potential hazards, such as small moons, rings, or dust, since mid-May. The decision on whether to keep the spacecraft on its original course or adopt a Safe Haven by Other Trajectory, or "SHBOT" path, had to be made this week since the last opportunity to maneuver New Horizons onto an alternate trajectory is July 4.
“Not finding new moons or rings present is a bit of a scientific surprise to most of us,” said principal investigator Alan Stern of the Southwest Research Institute (SwRI) in Boulder, Colorado. “But as a result, no engine burn is needed to steer clear of potential hazards. We presented these data to NASA for review and received approval to proceed on course and plan. We are ‘go’ for the best of our planned Pluto encounter trajectories.”
New Horizons formed a hazard analysis team in 2011, after the discovery of Pluto’s fourth moon, Kerberos, raised concerns the cratering of these moons by small debris from the outer area of the solar system known as the Kuiper Belt, could spread additional hazardous debris into New Horizons’ path. Mission engineers re-tested spare spacecraft blanketing and parts back on Earth to determine how well they would stand up to particle impacts, and scientists modeled the likely formation and locations of rings and debris in the Pluto system. By the time New Horizons’ cameras were close enough to Pluto to start the search last month, the team had already estimated the chances of a catastrophic incident at far less than one percent.
The images used in the latest searches that cleared the mission to stay on its current course were taken June 22, 23 and 26. Pluto and all five of its known moons are visible in the images, but scientists saw no rings, new moons, or hazards of any kind. The hazards team determined that satellites as faint as about 15 times dimmer than Pluto’s faintest known moon, Styx, would have been seen if they existed beyond the orbit of Pluto’s largest and closest moon, Charon.
If any rings do exist, the hazard team determined they must be extremely faint, reflecting less than one 5-millionth of the incoming sunlight.
“The suspense – at least most of it – is behind us,” says John Spencer, of SwRI, who leads the New Horizons hazard analysis team. “As a scientist I’m a bit disappointed that we didn’t spot additional moons to study, but as a New Horizons team member I am much more relieved that we didn’t find something that could harm the spacecraft. New Horizons already has six amazing objects to analyze in this incredible system.”
The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, designed, built, and operates the New Horizons spacecraft, and manages the mission for NASA’s Science Mission Directorate. The Southwest Research Institute, based in San Antonio, leads the science team, payload operations and encounter science planning. New Horizons is part of the New Frontiers Program managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama.

NASA : Light Toned Deposit in the Aureum Chaos Region on Mars .- Luz virada fuerte en laRegión Caos Aureum en Marte

Hola amigos: A VUELO DE UN QUINDE EL BLOG, hemos recibido información de la Agencia Espacial NASA, que el satélite orbital alrededor de Marte, NASA's Mars Reconnaissance Orbiter; ha captado unas luces.
NASA, nos dice: El Experimento de Imágenes de Alta Resolución Science (HiRISE) de la cámara a bordo del Mars Reconnaissance Orbiter de la NASA tomó esta imagen de cerca de un depósito de color claro en the Aureum Chaos Region on Mars, un 368 kilometros (229 millas) de ancho área en la parte oriental de Valles Marineris, el 15 de enero de 2015, a las 2:51 pm hora local de Marte.
El objetivo de esta observación es examinar un depósito de color claro en una región de lo que se denomina "terreno caótico." Hay indicios de capas en la imagen. Algunas formas sugieren la erosión por un movimiento fluido al norte y al sur. La parte superior del depósito de color claro parece áspero, en contraste con la suavidad de su entorno.

Light toned deposit with shadow on rough terrain
The High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA's Mars Reconnaissance Orbiter acquired this closeup image of a light-toned deposit in Aureum Chaos, a 368 kilometer (229 mile) wide area in the eastern part of Valles Marineris, on Jan. 15, 2015, at 2:51 p.m. local Mars time.
The objective of this observation is to examine a light-toned deposit in a region of what is called “chaotic terrain.” There are indications of layers in the image. Some shapes suggest erosion by a fluid moving north and south. The top of the light-toned deposit appears rough, in contrast to the smoothness of its surroundings.

The University of Arizona, Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., Boulder, Colorado. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project and Mars Science Laboratory Project for NASA's Science Mission Directorate, Washington.
