Like a ship plowing through cosmic seas, runaway star Zeta Ophiuchi produces the arcing interstellar bow wave or bow shock seen in this stunning infrared portrait. In the false-color view, bluish Zeta Oph, a star about 20 times more massive than the Sun, lies near the center of the frame, moving toward the left at 24 kilometers per second. Its strong stellar wind precedes it, compressing and heating the dusty interstellar material and shaping the curved shock front. Around it are clouds of relatively undisturbed material. What set this star in motion? Zeta Oph was likely once a member of a binary star system, its companion star was more massive and hence shorter lived. When the companion exploded as a supernova catastrophically losing mass, Zeta Oph was flung out of the system. About 460 light-years away, Zeta Oph is 65,000 times more luminous than the Sun and would be one of the brighter stars in the sky if it weren't surrounded by obscuring dust. The image spans about 1.5 degrees or 12 light-years at the estimated distance of Zeta Ophiuchi. via NASA ift.tt/1fcAp39

NASA’s first completed Orion crew module sits atop its service module at the Neal Armstrong Operations and Checkout Facility at Kennedy Space Center in Florida. The crew and service module will be transferred together on Wednesday to another facility for fueling, before moving again for the installation of the launch abort system. At that point, the spacecraft will be complete and ready to stack on top of the Delta IV Heavy rocket that will carry it into space on its first flight in December. For that flight, Exploration Flight Test-1, Orion will travel 3,600 miles above the Earth – farther than any spacecraft built to carry people has traveled in more than 40 years – and return home at speeds of 20,000 miles per hour, while enduring temperatures near 4,000 degrees Fahrenheit.

In this 1945 photo, test pilots (from left) Mel Gough, Herb Hoover, Jack Reeder, Steve Cavallo and Bill Gray stand in front of a P-47 Thunderbolt. The photo was taken at the then-named Langley Memorial Aeronautical Laboratory, which was a research facility for the National Advisory Committee for Aeronautics, or the NACA. The NACA was the main institutional basis for creating NASA in 1958. On March 3, 1915 – one hundred years ago -- the U.S. Congress established the NACA in order "to supervise and direct the scientific study of the problems of flight with a view to their practical solution." From humble beginnings with a $5000 budget, no paid staff and no facilities, the NACA won the Collier trophy five times. Its researchers made critical contributions to victory in World War II, spawned a world-leading civil aviation manufacturing industry, propelled supersonic flight, supported national security during the Cold War, and laid the foundation for modern air travel and the space age.

NASA has started an airborne science campaign to get a better understanding of what affects the composition of the atmosphere and the climate. The project is using specially equipped research planes.
NASA satellites have watched as wind shear has torn Cyclone Iggy apart over the last day. NASA infrared satellite imagery showed that Iggy's strongest thunderstorms have been pushed away from the storm's center and visible imagery shows the storm is being stretched out. Iggy is weakening and heading for a landfall between Geraldton and Perth.
When NASA's Aqua satellite passed over Tropical Cyclone Iggy on Feb. 1 at 1805 UTC (1:05 p.m. EST), the Atmospheric Infrared Sounder (AIRS) instrument aboard captured an infrared look at the cyclone. AIRS data showed that the strongest thunderstorms (with the coldest cloud top temperatures) had been pushed to the southeast of Iggy's center. That convection was pushed by vertical wind shear from the northwest. Once convection is pushed away from a tropical cyclone's center, the storm begins to fall apart. Tropical cyclones must be stacked in the atmosphere like a haystack. If the middle (convection in this case) gets pushed out, then the storm collapses.
The Moderate Resolution Imaging Spectroradiometer (MODIS) instrument aboard NASA's Aqua satellite captured a true color image of Iggy when it passed overhead on Feb. 2, 2012 at 0615 UTC (1:15 a.m. EST). The MODIS image clearly shows how the wind shear is affecting the tropical depression because Iggy appears elongated from northwest to southeast, which is the direction of the wind shear.
The Australian Bureau of Meteorology (ABM) issued severe weather warnings for residents from Kalbarri to Morawa, and from Morawa to Wongan Hills; and Wongan to Narrogin and Harvey. The ABM website noted that the warning includes people in, near or between the following towns: Geraldton, Jurien Bay, Perth, Mandurah, York and Narrogin. Those areas can expect thunderstorms with heavy rainfall, and gusty winds as Iggy continues moving east. Flash flooding is also a possibility from the heavy rainfall.
On February 2, 2012, Tropical Depression Iggy had maximum sustained winds near 30 knots (~35 mph/~56 kph). It was located about 170 nautical miles (~196 miles/~315 km) northwest of Perth, Western Australia, and its center was near 29.9 South latitude and 114.2 East longitude. Iggy was moving to the east at 14 knots (16 mph/~26 kph) and is expected to continue in that direction making landfall before 0300 UTC on February 3, 2012 (or before 10 p.m. EST, Feb. 3). Iggy is expected to quickly weaken to a remnant low as it moves further inland in Western Australia.

What's happening in this strange juxtaposition of moon and planet? First and foremost, Saturn's moon Dione was captured here in a dramatic panorama by the robotic Cassini spacecraft currently orbiting the giant planet. The bright and cratered moon itself spans about 1100-km, with the large multi-ringed crater Evander visible on the lower right. Since the rings of Saturn are seen here nearly edge-on, they are directly visible only as a thin horizontal line that passes behind Dione. Arcing across the bottom of the image, however, are shadows of Saturn's rings, showing some of the rich texture that could not be seen directly. In the background, few cloud features are visible on Saturn. The featured image was taken during the last planned flyby of Dione by Cassini, as the spacecraft is scheduled to dive into Saturn's atmosphere during 2017. via NASA ift.tt/1Jf3ODS
There is no sea on Earth large enough to contain the Shark nebula. This predator apparition poses us no danger, though, as it is composed only of interstellar gas and dust. Dark dust like that featured here is somewhat like cigarette smoke and created in the cool atmospheres of giant stars. After being expelled with gas and gravitationally recondensing, massive stars may carve intricate structures into their birth cloud using their high energy light and fast stellar winds as sculpting tools. The heat they generate evaporates the murky molecular cloud as well as causing ambient hydrogen gas to disperse and glow red. During disintegration, we humans can enjoy imagining these great clouds as common icons, like we do for water clouds on Earth. Including smaller dust nebulae such as Lynds Dark Nebula 1235 and Van den Bergh 149 & 150, the Shark nebula spans about 15 light years and lies about 650 light years away toward the constellation of the King of Aethiopia (Cepheus). via NASA ift.tt/1NX1OEk

Check this out from NASA -- This close-up from the Mars Reconnaissance Orbiter's HiRISE camera shows weathered craters and windblown deposits in southern Acidalia Planitia. A striking shade of blue in standard HiRISE image colors, to the human eye the area would probably look grey or a little reddish. But human eyes have not gazed across this terrain, unless you count the eyes of NASA astronauts in the scifi novel The Martian by Andy Weir. The novel chronicles the adventures of Mark Watney, an astronaut stranded at the fictional Mars mission Ares 3 landing site corresponding to the coordinates of this cropped HiRISE frame. For scale Watney's 6-meter-diameter habitat at the site would be about 1/10th the diameter of the large crater. Of course, the Ares 3 landing coordinates are only about 800 kilometers north of the (real life) Carl Sagan Memorial Station, the 1997 Pathfinder landing site. (go.nasa.gov/2ZEWoH2)
