Reddish Bands on Europa: This colorized image of Jupiter's moon Europa is a product of clear-filter grayscale data from one orbit of our Galileo spacecraft, combined with lower-resolution color data taken on a different orbit. The blue-white terrains indicate relatively pure water ice, whereas the reddish areas contain water ice mixed with hydrated salts, potentially magnesium sulfate or sulfuric acid. The reddish material is associated with the broad band in the center of the image, as well as some of the narrower bands, ridges, and disrupted chaos-type features. It is possible that these surface features may have communicated with a global subsurface ocean layer during or after their formation.

Our Next Giant Leap: The first humans who will step foot on Mars are walking the Earth today. It was 45 years ago that Neil Armstrong took the small step onto the surface of the moon that changed the course of history. The years that followed saw a Space Age of scientific, technological and human research, on which we have built the modern era. We stand on a new horizon, poised to take the next giant leap—deeper into the solar system. The Apollo missions blazed a path for human exploration to the moon and today we are extending that path to near-Earth asteroids, Mars and beyond. This is an artist's concept image of a boot print on the moon and on Mars. Image Credit: NASA #nasa #nextgiantleap #apllo45 #path2mars #mars #moon #apollo11 Instagram ดารา @nasa 3,828

Changes Near Downhill End of a Martian Gully: This image of the surface of Mars covers a location that has been captured several times by the HiRISE camera aboard our Mars Reconnaissance Orbiter to look for changes in gullies. Changes have now been seen in many gullies on Mars, and show that these landforms are evolving rapidly. The timing of the changes is often in winter or early spring, suggesting that they are caused by the carbon dioxide frost that forms in and around most gullies every year.

Orbital Sciences' Antares rocket carrying the Cygnus cargo spacecraft lifted off at 12:52 p.m. EDT and is on its way to the International Space Station. At the time of launch, the International Space Station was traveling at an altitude of 260 miles over northwest Australia. The Cygnus spacecraft is safely on orbit with solar arrays deployed. The cargo ship will rendezvous with the International Space Station on Wednesday, July 16. It will be grappled at approximately 6:39 a.m. by Commander Steve Swanson of NASA. He will be assisted in a backup position by Flight Engineer Alexander Gerst of the European Space Agency. Cygnus will be attached to the Earth-facing port of the station's Harmony node and will remain in place for approximately one month. It is scheduled depart the space station on August 15.

Today marks 5,000 consecutive days of humans living & working aboard the International Space Station. That's almost 14 years going strong. The space station, including its large solar arrays, spans the area of a U.S. football field, including the end zones, and weighs 924,739 pounds. The complex now has more livable room than a conventional six-bedroom house, and has two bathrooms, a gymnasium and a 360-degree bay window. The orbiting outpost has been a platform for hundreds of science experiments. This image shows the ISS in May 2010 from the undocking STS-132 Space Shuttle mission to the orbiting outpost.

Galaxy With a Glowing Heart: This view, captured by the Hubble Space Telescope, shows a nearby spiral galaxy known as NGC 1433. At about 32 million light-years from Earth, it is a type of very active galaxy known as a Seyfert galaxy — a classification that accounts for 10% of all galaxies. They have very bright, luminous centers that are comparable in brightness to that of our entire galaxy, the Milky Way. The centers of most galaxy cores, if not all, galaxies are thought to contain a supermassive black hole, surrounded by a disk of in-falling material.

A Spiral Bridge of Young Stars Linking Two Ancient Galaxies: Our Hubble Space Telescope photographed an unusual structure 100,000 light years long, which resembles a corkscrew-shaped string of pearls and winds around the cores of two colliding galaxies. The unique structure of the star spiral may yield new insights into the formation of stellar superclusters that result from merging galaxies and gas dynamics in this rarely seen process.

Typhoon Neoguri in Moonlight: The storm pounded Okinawa and other Western Pacific islands with torrential rain and damaging winds in mid-July 2014, en route to a likely landfall in Japan. The Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite captured this nighttime image of the storm at 2:07 a.m. Japan Standard Time on July 9, 2014 (17:07 Universal Time on July 8). At the time, Neoguri was a category 2 typhoon moving through the East China Sea. The storm was imaged by a special “day-night band” that detects light in a range of wavelengths from green to near-infrared and uses light intensification to detect dim signals. The instrument can sense light as much as 100,000 times fainter than conventional visible-light sensors, making it very sensitive to moonlight and city lights. In this case, the cloud tops were lit by the nearly full Moon. Image Credit: NASA #nasa #space #satellite #weather #climate #nhc #typhoonneoguri #typhoon #neoguri Instagram ดารา @nasa 18,206

Prototype Robot With Smartphone to Test 3-D Mapping, Navigation Inside Space Station: Orbital Sciences Corporation's Cygnus spacecraft will carry 3,293 pounds (1,493.8 kg) of cargo on its upcoming commercial resupply mission to the station, including crew supplies, nanosatellites, student research and this prototype free-flying space robot equipped with a smartphone, known as Smart SPHERES (Synchronized Position Hold, Engage, Reorient Experimental Satellites). We've been testing SPHERES on the space station since 2011. This summer, astronauts will upgrade these existing space robots to use Google’s "Project Tango" smartphone, which features a custom 3-D sensor and multiple cameras. We will then use the Smart SPHERES to test free-flying 3-D mapping and navigation inside the space station.

Saturn's Vortex and Rings The Cassini spacecraft captures three magnificent sights at once: Saturn's north polar vortex and hexagon along with its expansive rings. The hexagon, which is wider than two Earths, owes its appearance to the jet stream that forms its perimeter. The jet stream forms a six-lobed, stationary wave which wraps around the north polar regions at a latitude of roughly 77 degrees North. This view looks toward the sunlit side of the rings from about 37 degrees above the ringplane. The image was taken with the Cassini spacecraft wide-angle camera on April 2, 2014 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 1.4 million miles (2.2 million kilometers) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 43 degrees. Image scale is 81 miles (131 kilometers) per pixel. Credit: NASA/JPL-Caltech/Space Science Institute #nasa #cassini #saturn #solarsystem #saturnrings #space Instagram ดารา @nasa 19,631
