TRACKING THE ORIGINS OF SPEEDY SPACE PARTICLES

NASA's Time History of Events and Macroscale Interaction during Substorms (THEMIS) spacecraftcombined with computer models have helped track the origin of the energetic particles in Earth's magnetic atmosphere that appear during a kind of space weather called a substorm. Understanding the source of such particles and how they are shuttled through Earth's atmosphere is crucial to better understanding the Sun's complex space weather system and thus protect satellites or even humans in space.





The results show that these speedy electrons gain extra energy from changing magnetic fields far from the origin of the substorm that causes them. THEMIS, which consists of five orbiting satellites, helped provide these insights when three of the spacecraft traveled through a large substorm on February 15, 2008. This allowed scientists to track changes in particle energy over a large distance. The observations were consistent with numerical models showing an increase in energy due to changing magnetic fields, a process known as betatron acceleration.

NASA TESTING OF COMMERCIAL ENGINE FLIES HIGH

You see a lot of smiles around the E-1 Test Stand at John C. Stennis Space Center these days. Engineers involved in testing Aerojet's AJ26 rocket engine for Orbital Sciences Corporation's Taurus II space launch vehicle have good reason to smile.


In fact, they have several good reasons given that the partnership between NASA, Orbital and Aerojet is off to such an impressive start. Two successful tests of an AJ26 engine that will power the first stage of Orbital's Taurus II rocket recently wrapped up at Stennis. The two tests were so successful that Orbital engineers decided a planned third test was unnecessary. The AJ26 engine used in the testing was removed from the E-1 stand on Jan. 24, and will be returned to Aerojet in Sacramento, Calif. to be refurbished and used on an upcoming Taurus II mission.

NASA'S HUBBLE FINDS MOST DISTANT GALAXY CANDIDATE EVER SEEN IN UNIVERSE


Astronomers have pushed NASA's Hubble Space Telescope to its limits by finding what is likely to be the most distant object ever seen in the universe. The object's light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder. The age of the universe is approximately 13.7 billion years.



The tiny, dim object is a compact galaxy of blue stars that existed 480 million years after the big bang. More than 100 such mini-galaxies would be needed to make up our Milky Way. The new research offers surprising evidence that the rate of star birth in the early universe grew dramatically, increasing by about a factor of 10 from 480 million years to 650 million years after the big bang.

NASA'S FIRST SOLAR SAIL NANOSAIL-D DEPLOYS IN LOW-EARTH ORBIT


HUNTSVILLE, Ala. – Friday, Jan. 21 at 10 a.m. EST, engineers at NASA's Marshall Space Flight Center in Huntsville, Ala., confirmed that the NanoSail-D nanosatellite deployed its 100-square-foot polymer sail in low-Earth orbit and is operating as planned. 



Actual deployment occurred on Jan. 20 at 10 p.m. EST and was confirmed today with beacon packets data received from NanoSail-D and additional ground-based satellite tracking assets. In addition, the NanoSail-D orbital parameter data set shows an appropriate change which is consistent with sail deployment. "This is tremendous news and the first time NASA has deployed a solar sail in low-Earth orbit," said Dean Alhorn, NanoSail-D principal investigator and aerospace engineer at the Marshall Center.

NASA’S GLORY MISSION WILL STUDY KEY PIECES OF THE CLIMATE PUZZLE


Earth’s climate continues to change at a rapid pace. Last week, NASA announced that 2010 was tied as the warmest year on record. Likewise, the last decade was the warmest in the 130-year global temperature record maintained by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York City.


Meanwhile, at Vandenberg Air Force Base in California, engineers are preparing NASA’s next Earth-observing mission  a satellite called Glory for launch in late February. The satellite, which contains two instruments that will monitor key parts of the climate system, aims to offer a new stream of data that climatologists will use as part of an ongoing effort to improve the accuracy of climate models.

SWIFT SURVEY FINDS 'MISSING' ACTIVE GALAXIES


Seen in X-rays, the entire sky is aglow. Even far away from bright sources, X-rays originating from beyond our galaxy provide a steady glow in every direction. Astronomers have long suspected that the chief contributors to this cosmic X-ray background were dust-swaddled black holes at the centers of active galaxies. The trouble was, too few of them were detected to do the job.


An international team of scientists using data from NASA's Swift satellite confirms the existence of a largely unseen population of black-hole-powered galaxies. Their X-ray emissions are so heavily absorbed that little more than a dozen are known. Yet astronomers say that despite the deeply dimmed X-rays, the sources may represent the tip of the iceberg, accounting for at least one-fifth of all active galaxies.

A FIRST LOOK AT FLIGHT IN 2025


In late 2010, NASA awarded contracts to three teams Lockheed Martin Northrop Grumman, The Boeing Company  to study advanced concept designs for aircraft that could take to the skies in the year 2025.

At the time of the award, the team gave NASA a sneak peek of the particular design they plan to pursue.Each design looks very different, but all final designs have to meet NASA's goals for less noise, cleaner exhaust and lower fuel consumption. Each aircraft has to be able to do all of those things at the same time, which requires a complex dance of tradeoffs between all of the new advanced technologies that will be on these vehicles.

THE TWO-FACED WHIRLPOOL GALAXY


These images by NASA's Hubble Space Telescope show off two dramatically different face-on views of the spiral galaxy M51, dubbed the Whirlpool Galaxy.The image at left, taken in visible light, highlights the attributes of a typical spiral galaxy, including graceful, curving arms, pink star-forming regions, and brilliant blue strands of star clusters.


In the image at right, most of the starlight has been removed, revealing the Whirlpool's skeletal dust structure, as seen in near-infrared light. This new image is the sharpest view of the dense dust in M51. The narrow lanes of dust revealed by Hubble reflect the galaxy's moniker, the Whirlpool Galaxy, as if they were swirling toward the galaxy's core.

NASA TELESCOPES HELP FIND MOST DISTANT GALAXY CLUSTER


Astronomers have uncovered a burgeoning galactic metropolis, the most distant known in the early universe. This ancient collection of galaxies presumably grew into a modern galaxy cluster similar to the massive ones seen today.


The developing cluster, named COSMOS-AzTEC3, was discovered and characterized by multi-wavelength telescopes, including NASA's Spitzer, Chandra and Hubble space telescopes and the ground-based W.M. Keck Observatory and Japan's Subaru Telescope.

NASA SATELLITES FIND HIGH-ENERGY SURPRISES IN 'CONSTANT' CRAB NEBULA


The combined data from several NASA satellites has astonished astronomers by revealing unexpected changes in X-ray emission from the Crab Nebula, once thought to be the steadiest high-energy source in the sky.

"For 40 years, most astronomers regarded the Crab as a standard candle," said Colleen Wilson-Hodge, an astrophysicist at NASA's Marshall Space Flight Center in Huntsville, Ala., who presented the findings today at the American Astronomical Society meeting in Seattle. "Now, for the first time, we're clearly seeing how much our candle flickers."

IN DISTANT GALAXIES, NEW CLUES TO CENTURY-OLD MOLECULE MYSTERY


In a study that pushes the limits of observations currently possible from Earth, a team of NASA and European scientists recorded the "fingerprints" of mystery molecules in two distant galaxies, Andromeda and the Triangulum. Astronomers can count on one hand the number of galaxies examined so far for such fingerprints, which are thought to belong to large organic molecules, says the team's leader, Martin Cordiner of the Goddard Center for Astrobiology at NASA's Goddard Space Flight Center in Greenbelt, Md.


Figuring out exactly which molecules are leaving these clues, known as "diffuse interstellar bands" (DIBs), is a puzzle that initially seemed straightforward but has gone unsolved for nearly a hundred years. The answer is expected to help explain how stars, planets and life form, so settling the matter is as important to astronomers who specialize in chemistry and biology as determining the nature of dark matter is to the specialists in physics.

ANDROMEDA IS SO HOT 'N' COLD


This mosaic of the Andromeda spiral galaxy highlights explosive stars in its interior, and cooler, dusty stars forming in its many rings. The image is a combination of observations from the Herschel Space Observatory taken in infrared light (seen in orange hues), and the XMM-Newton telescope captured in X-rays (seen in blues). NASA plays a role in both of these European Space Agency-led missions.


Herschel provides a detailed look at the cool clouds of star birth that line the galaxy's five concentric rings. Massive young stars are heating blankets of dust that surround them, causing them to glow in the longer-wavelength infrared light, known as far-infrared, that Herschel sees.

Under Pressure: Stormy Weather Sensor for Hurricane Forecasting


It’s hard to believe that, in this day and age, we don’t have a way to measure sea-level air pressure during hurricanes. NASA researchers however, are working on a system that will improve forecasting of severe ocean weather by doing just that. The device measures sea-level air pressure, a critical component of hurricane formation – and one that has been extremely difficult to capture.


The Differential Absorption Barometric Radar (DIABAR) prototype is scheduled to make its second flight early this year.DIABAR remotely senses barometric pressure at sea level, which is important in the prediction and forecasting of severe weather, especially hurricanes over oceans.

HOTSPOTS IN FOUNTAINS ON THE SUN'S SURFACE HELP EXPLAIN CORONAL HEATING MYSTERY

Among the many constantly moving, appearing, disappearing and generally explosive events in the sun's atmosphere, there exist giant plumes of gas as wide as a state and as long as Earth that zoom up from the sun's surface at 150,000 miles per hour. Known as spicules, these are one of several phenomena known to transfer energy and heat throughout the sun's magnetic atmosphere, or corona.

Thanks to NASA's Solar Dynamics Observatory (SDO) and the Japanese satellite Hinode, these spicules have recently been imaged and measured better than ever before, showing them to contain hotter gas than previously observed. Thus, they may perhaps play a key role in helping to heat the sun's corona to a staggering million degrees or more. (A number made more surprising since the sun's surface itself is only about 10,000 degrees Fahrenheit.)

NASA RESEARCH TEAM REVEALS MOON HAS EARTH-LIKE CORE


State-of-the-art seismological techniques applied to Apollo-era data suggest our moon has a core similar to Earth's.


Uncovering details about the lunar core is critical for developing accurate models of the moon's formation. The data sheds light on the evolution of a lunar dynamo a natural process by which our moon may have generated and maintained its own strong magnetic field. The researchers used extensive data gathered during the Apollo-era moon missions. The Apollo Passive Seismic Experiment consisted of four seismometers deployed between 1969 and 1972, which recorded continuous lunar seismic activity until late-1977.
