<span style="font-family: Arial,Helvetica,sans-serif;">It's the season for sequels. Not only in Hollywood, but over the high desert of California as well.For the second time in as many years, NASA researchers beginning in early May will take to the skies with a DC-8 and other aircraft to conduct a series of flight tests designed to study the effects on emissions and contrail formation of burning alternative fuels in jet engines.<br /><br />And just like a good movie sequel, this year's Alternative Fuel Effects on Contrails and Cruise Emissions flight tests, known as ACCESS II for short, will feature a number of new plot twists to keep the research story interesting and moving forward. Among them are new science instruments, new flight profiles to follow and a decidedly new international flavor to the effort thanks to the direct participation of research aircraft and scientists from Germany and Canada.<br /><br />"We’re going to have quite a few people speaking German. We’ll have some Canadians present and the pilot for the Canadian aircraft is Australian, so it should be a real international crowd out there," said Brian Beaton, NASA's ACCESS II integration manager. ACCESS II involves flying NASA's workhorse DC-8 as high as 40,000 feet while its four CFM56 engines burn either JP-8 jet fuel, or a 50-50 blend of JP-8 and renewable alternative fuel of hydro processed esters and fatty acids produced from camelina plant oil.<br /><br />Meanwhile, a trio of instrumented research aircraft will take turns flying behind the DC-8 at distances ranging from 300 feet to more than 10 miles in order to take measurements on emissions, and to study contrail formation as the different fuels are used.<br /><br />The aircraft will include NASA's HU-25C Guardian jet based at NASA's Langley Research Center in Virginia, a Falcon 20-E5 jet owned by the German <a href="http://nasa-spacestation-info.blogspot.in/2011/09/nasas-wise-mission-captures-black-holes.html" target="_blank"><span style="color: orange;" title="Aerospace Center"><b>Aerospace Center</b></span></a>, and a CT-133 jet provided by the National Research Council of Canada.<br /><br />"We are excited to be working with our international partners in this very important research that could lead to worldwide environmental benefits and enable the growth in global air travel forecast for the decades ahead," said Ruben Del Rosario, manager of NASA's Fixed Wing Project.</span></div>

These tides occur for the reason that Europa travels around Jupiter in a slightly oval-shaped range to after Europa comes closer to the planet, the moon gets stretched like a rubber band, with the ocean height at the long ends increasing nearly 100 feet (30 meters). That's approximately as high as the 2004 tsunami in the Indian Ocean, but it happens on a body that events only about one-quarter of Earth's diameter as Europa moves farther from Jupiter, it relaxes back into the shape of a ball.</span></div>

<br />
The group, using a high-pixel imaging spectrograph called OSIRIS, exposed the chemical fingerprints of exact molecules, informative a cloudy atmosphere holds carbon monoxide and water vapor. They can evaluate the amount of carbon to the amount of oxygen nearby in the planet's atmosphere, and this chemical mix offers clues as to how the whole terrestrial system shaped. <br />
<br />
There has been significant hesitation about how systems of planets shape, with two leading models, called core buildup and gravitational volatility. Planetary properties, such as the composition of a planet's atmosphere, are clues as to whether a system produced according to one model or the other.

Astrophysicists trust it will give a pristine view of the element in the exterior Solar System 4.6 billion years before, when ISON produced.<br />
<div align="justify">
<br />
Russian researchers have up till now exposed a comet that is temporary by our plant and will be capable to be seen in 2013 with naked eyes over the western hope. The examination, called ISON, is credible to shine up to 15 times the moon depending on how giant its end will get when it catches sooner to the sun.<br />
<br />
Even though the technicians are unsure to estimate its actions, but the positioning of ISON comet at recent details that it will be fine obvious over India in 2013. It will reside a two thousand mile distance from the sun.<br />
<br />
Due to the glow expected, the comet will be manifest even in day time. If so, ISON will be the clearest comet always revealed by technicians in the last century. But some technicians think that the outing by our planet may be ISON’S last as it may drive into the sun appropriate to its irregular way.<br />
<br />
ISON is a two mile wide body formed out of rocks and ice. It is currently passing by Saturn, and is gaining speed. It is satisfying brighter day by day as it closer to our planet.<br />
<br />
As the black hole, called Sagittarius A, gathers a mere 25,000 light years gone - on our space entry - the crash must provide a matchless idea of substance restricting into a black hole.<br />
<br />
It could even give up imperative hints about what happened 300 years ago, when the <b><a href="http://nasa-spacestation-info.blogspot.in/2012/10/black-hole-in-milky-way.html"><span style="color: blue;">black hole</span></a></b> was much brighter than currently.<br />

<div align="justify">
New observations by the herald spaceship give convincing sustain for the long-held theory that Mercury port copious water ice and further freezing fickle resources in its enduringly outlined polar craters.<br />
<b><br /></b>
<b>Three independent ways of facts maintain this conclusion:</b><br />
<b><br /></b>
The first dimensions of surplus hydrogen at Mercury's north pole among herald‘s Neutron <span style="color: cyan;"><a href="http://www.nasa-spacestation-info.blogspot.in/2012/01/pasadena-calif.html" target="_blank"><span style="color: cyan;">Spectromete</span>r</a>,</span> the first measurement of the reluctance of Mercury's polar places at close to ultraviolet wavelengths among the Mercury Laser Altimeter (MLA), and the first complete models of the exterior and close to external heat of Mercury's north polar constituencies that exploit the definite geography of Mercury's surface calculated by the MLA.<br />

<br />
Herald’s advent at Mercury last year altered that. Visions from the spacecraft's Mercury twin Imaging System taken in 2011 and former this year inveterate that radar-vivid features at Mercury's north and south limits are within outlined areas on Mercury's exterior, conclude that are reliable with the water-ice theories.<br />
<br />
Currently the latest information from emissary sturdily specify that water ice is the main ingredient of Mercury's north glacial dumps, that ice is showing at the exterior in the most icy of those places, other than that the ice is covered below an curiously dark objects cross ways most of the leaves, regions where heats are a bit too temperate for ice to be constant at the exterior itself. <br />

<span style="text-align: left;">Information from emissary’s Mercury Laser Altimeter (MLA) which has redundant more than 10 million laser beats at Mercury to create complete records of the planet's geography confirm the radar results and Neutron Spectrometer dimensions of Mercury's polar expanse. In a second report, that the first MLA dimensions of the outlined north Polar Regions expose unequal murky and light place at near to ultraviolet wavelength close to Mercury's North edge.</span></div>

The classification of minerals in rocks and soil is crucial for the charge’s aim to review precedent ecological conditions. Each mineral proof the setting below which it shaped.

<a href="http://post.jagran.com/nasas-swift-satellite-discovers-new-black-hole-in-milky-way-1349602485">NASA's Swift satellite</a> freshly spotted an increasing wave of high-energy X-rays from a starting place to the middle of our Milky Way galaxy. The explosion, created by an atypical X-ray nova, publicized the occurrence of an earlier strange stellar-mass black hole.<br />

<br />
An X-ray nova is short-term X-ray sources that emerge rapidly, achieves its production crest in some days and then become paler out over a time of months. The explosions begin when a gush of gathering gas rapidly runs near one of the densest objects known, moreover a neutron star or a <a href="http://www.nasa-spacestation-info.blogspot.in/2012/02/ultra-fast-outflows-help-monster-black.html">black hole</a>. <br />

<br />
<br />
The black hole must be a part of a low-mass X-ray binary (LMXB) system, which includes a standard, sun-like star. A flow of gas pours from the ordinary star and come into a storage diskette around the black hole. In most LMXBs, the gas in the disk curves inmost warms up as it top toward the black hole, and makes a stable stream of X-rays.

Preliminary data recommences that one of the rocket’s nine Merlin engines, Engine 1, lost force suddenly and an engine shutdown command was issued. Gastronomes know the engine did not burst, because they sustained to get data from it. Panels designed to reduce stress within the engine cove were evicted to shield the stage and other engines. Finally their review of flight data points out that neither the sky rocket phase nor any of the further eight engines were unenthusiastically precious by this experience.<br />
<br />
When intended, the flight workstation after that recomputed a new climb contour in real time to make sure Dragon’s access into orbit for succeeding meeting and berthing with the ISS. This was accomplished, and here be no result on Dragon or the cargo resupply assignment. <br />

While some galaxies are rotund and others are slender disks like our spiral Milky Way, new observations from NASA's Spitzer Space Telescope show that the Sombrero galaxy is both. The galaxy, which is a round elliptical galaxy with a thin disk embedded inside, is one of the first known to exhibit characteristics of the two different types. The findings will lead to a better understanding of <a style="color: rgb(51, 102, 255); font-weight: bold;" href="http://nasa-spacestation-info.blogspot.in/2012/04/spiral-galaxy-in-hydra.html" title="galaxy">galaxy</a> evolution, a topic still poorly understood.</span><br /><br /><span style="font-family:arial;">"The Sombrero is more complex than previously thought," said Dimitri Gadotti of the European Southern Observatory in Chile and lead author of a new paper on the findings appearing in the Monthly Notices of the Royal Astronomical Society.

The image was captured by the NASA/ESA Hubble Space Telescope's Wide Field Planetary Camera 2.<br /><br />The stellar grouping is known to stargazers as NGC 2040 or LH 88. It is essentially a very loose star cluster whose stars have a common origin and are drifting together through space. There are three different types of stellar associations defined by their stellar properties. NGC 2040 is an OB association, a grouping that usually contains 10 to 100 stars of type O and B these are high-mass <a style="color: rgb(51, 102, 255); font-weight: bold;" href="http://nasa-spacestation-info.blogspot.in/2012/04/cosmic-leaf-blower-robs-galaxy-of-star.html" title="stars">stars</a> that have short but brilliant lives.<br /><br />It is thought that most of the stars in the Milky Way were born in OB associations.<br /><br />There are several such groupings of stars in the LMC. Just like the others, LH 88 consists of several high-mass young stars in a large nebula of partially ionized hydrogen gas, and lies in what is known to be a supergiant shell of gas called LMC 4.<br /><br />Over a period of several million years, thousands of stars may form in these supergiant shells, which are the largest interstellar structures in <a style="color: rgb(51, 102, 255); font-weight: bold;" href="http://nasa-spacestation-info.blogspot.in/2012/04/spiral-galaxy-in-hydra.html" title="galaxies">galaxies</a>.

Herschel’s new images of the belt show it in much more detail at longer infrared wavelengths than ever before.<br /><br />The results indicate the grains in the dust belt are fluffy and tiny, only a few millionths of a meter across (one meter is about 3 feet). They are similar to dust particles released from comets in our own solar system.<br /><br />Bram Acke of the University of Leuven in Belgium led the observations. He and his colleagues say the dust is being regenerated in the belt through continuous collisions between comets. Each day, the equivalent of either two comets 6.2 miles in size (10 kilometers) or 2,000 comets .62 miles in size (1 <a style="color: rgb(51, 102, 255); font-weight: bold;" href="http://nasa-spacestation-info.blogspot.in/2011/04/wise-delivers-millions-of-galaxies.html" title="kilometer">kilometer</a>) must be completely crushed into small fluffy, dust particles. What's more, there are a ton of comets: the team estimates between 260 billion and 83 trillion in the belt!<br /></div>NASA Satelliteshttp://www.blogger.com/profile/17324021915700247663noreply@blogger.com0tag:blogger.com,1999:blog-6088603898521102418.post-6886737425465352162012-04-12T11:44:00.005-07:002012-04-12T11:50:14.157-07:00Flying Formation Around the Moon at 3,600 MPH<div style="text-align: justify;"><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/-9I3Nls6t1OI/T4ci1yrNZbI/AAAAAAAACDY/LrUM5PdFjv0/s1600/Flying%2Bformation.jpg"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 320px; height: 275px;" src="http://2.bp.blogspot.com/-9I3Nls6t1OI/T4ci1yrNZbI/AAAAAAAACDY/LrUM5PdFjv0/s320/Flying%2Bformation.jpg" alt="" id="BLOGGER_PHOTO_ID_5730587358383662514" title="Flying formation" border="0" /></a><span style="font-family:arial;">The act of two or more aircraft <a style="color: rgb(51, 102, 255); font-weight: bold;" href="http://nasa-spacestation-info.blogspot.in/2010/07/nasa-to-fly-into-hurricane-research.html" title="flying">flying</a> together in a disciplined, synchronized manner is one of the cornerstones of military aviation, as well as just about any organized air show. But as amazing as the U.S. Navy's elite Blue Angels or the U.S. Air Force's Thunder birds are to behold, they remain essentially landlocked, anchored if you will, to our planet and its tenuous atmosphere.

"We need to do this so our scientists can get the data they need."</span><br /><br /><span style="font-family:arial;">Essentially, trail formation means one aircraft (or spacecraft in this case), follows directly behind the other. Ebb and Flow, the twins of NASA's GRAIL (Gravity Recovery And Interior Laboratory) mission, are by no means the first to synch up altitude and "air" speed while zipping over the craters, mountains, hills and rills of Earth's natural satellite. That honor goes to the crew of Apollo 10, who in May 1969 performed a dress rehearsal for the first lunar landing. But as accurate as the astronauts aboard lunar module "Snoopy" and command module "Charlie Brown" were in their piloting, it is hard to imagine they could keep as exacting a position as Ebb and Flow. "It is an apples and oranges comparison," said Lehman. "Lunar formation in Apollo was about getting a crew to the lunar surface, returning to lunar orbit and docking, so they could get back safely to <a style="color: rgb(51, 102, 255); font-weight: bold;" href="http://nasa-spacestation-info.blogspot.in/2010/07/microsoft-and-nasa-bring-mars-down-to.html" title="Earth">Earth</a>. For GRAIL, the formation flying is about the science, and that is why we have to make our measurements so precisely." </span><br /></div>NASA Satelliteshttp://www.blogger.com/profile/17324021915700247663noreply@blogger.com0tag:blogger.com,1999:blog-6088603898521102418.post-19088696890499970252012-04-11T11:11:00.003-07:002012-04-11T11:20:24.277-07:0012-Mile-High Martian Dust Devil Caught in Act<div style="text-align: justify;"><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/-gG_60sRJSqI/T4XJ_WNluBI/AAAAAAAACDA/3NSc9DZ4g9E/s1600/dust%2Bdevil%2Bcaught.jpg"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 320px; height: 238px;" src="http://2.bp.blogspot.com/-gG_60sRJSqI/T4XJ_WNluBI/AAAAAAAACDA/3NSc9DZ4g9E/s320/dust%2Bdevil%2Bcaught.jpg" alt="" id="BLOGGER_PHOTO_ID_5730208191030343698" title="Dust Devil Caught" border="0" /></a><span style="font-family:arial;">A Martian dust devil roughly 12 miles high (20 kilometers) was captured whirling its way along the Amazonis Planitia region of <a style="color: rgb(51, 102, 255); font-weight: bold;" href="http://nasa-spacestation-info.blogspot.in/2011/02/northern-mars-landscape-actively.html" title="Northern">Northern</a> Mars on March 14.

These cells looked somewhat like a cell pattern that occurs on the sun's surface similar to the bubbles that rise to the top of boiling water but it was a surprise to find this pattern higher up in the corona, which is normally dominated by bright loops and dark coronal <a style="color: rgb(51, 102, 255); font-weight: bold;" href="http://nasa-spacestation-info.blogspot.in/2010/11/nasas-chandra-finds-youngest-nearby.html" title="holes">holes</a>.</span><br /><br /><span style="font-family:arial;">Sheeley discussed the images with his Naval Research Laboratory colleague Harry Warren, and together they set out to learn more about the cells. Their search included observations from a fleet of NASA spacecraft called the Heliophysics System Observatory that provided separate viewpoints from different places around the sun. They describe the properties of these previously unreported solar features, dubbed "coronal cells," in a paper published online in The <a style="color: rgb(51, 102, 255); font-weight: bold;" href="http://nasa-spacestation-info.blogspot.in/2010/11/astronomers-probe-sandbar-between.html" title="Astrophysical">Astrophysical</a> Journal on March 20, 2012 that will appear in print on April 10.</span><br /><br /><span style="font-family:arial;">The coronal cells occur in areas between coronal holes colder and less dense areas of the corona seen as dark regions in images and "filament channels" which mark the boundaries between sections of upward-pointing magnetic fields and downward-pointing ones. Understanding how these cells evolve can provide clues as to the changing magnetic fields at the boundaries of coronal holes and how they affect the steady emission of solar material known as the solar wind streaming from these holes.</span><br /></div>NASA Satelliteshttp://www.blogger.com/profile/17324021915700247663noreply@blogger.com0tag:blogger.com,1999:blog-6088603898521102418.post-47297525580001425872012-04-09T11:49:00.003-07:002012-04-09T11:59:09.628-07:00Look Out for Those Rocks!<div style="text-align: justify;"><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/-RanAy0mN6pw/T4Mv587w40I/AAAAAAAACCo/sf-SUyBnxPU/s1600/Kennedy%2527s%2BShuttle%2BLanding.jpg"><img style="display: block; margin: 0px auto 10px; text-align: center; cursor: pointer; width: 320px; height: 183px;" src="http://1.bp.blogspot.com/-RanAy0mN6pw/T4Mv587w40I/AAAAAAAACCo/sf-SUyBnxPU/s320/Kennedy%2527s%2BShuttle%2BLanding.jpg" alt="" id="BLOGGER_PHOTO_ID_5729475823601247042" title="Kennedy's Shuttle Landing" border="0" /></a><span style="font-family:arial;">The words "hazard field" certainly never were associated with the Shuttle Landing Facility at <a style="color: rgb(51, 102, 255); font-weight: bold;" href="http://nasa-spacestation-info.blogspot.in/2012/03/nasa-researchers-on-snow-patrol.html" title="National Aeronautics and Space Administration">NASA's</a> Kennedy Space Center in Florida. To the contrary, the goal was to keep the runway area free of any hazards that might endanger the shuttle and crew during landing.
