Title Cassiopeia A - The Colorful Aftermath of a Violent Stellar Death
General Information What is Hubble Heritage? A monthly showcase of new and archival Hubble images. Go to the Heritage site. A new image taken with NASA's Hubble Space Telescope provides a detailed look at the tattered remains of a supernova explosion known as Cassiopeia A (Cas A). It is the youngest known remnant from a supernova explosion in the Milky Way. The new Hubble image shows the complex and intricate structure of the star's shattered fragments. The image is a composite made from 18 separate images taken in December 2004 using Hubble's Advanced Camera for Surveys (ACS).
Sequence of images recorded …
Description Sequence of images recorded by the LASCO C2 coronagraph showing the big coronal mass ejection of April 7, 1997 (see also EIT image eit022.gif and the special page of the April 7-9 event at http://www-istp.gsfc.nasa.gov/istp/cloud_apr97). A coronagraph is a device to observe the faint outer solar atmosphere by blocking out the brightness of the sun itself. The circle in the images shows where the sun would be if it wasn't blocked out. The first frame shows the corona just before the eruption. The first stage of the eruption is seen in the upper right-hand corner. The eruption proceeds into a "halo" event: in the fourth image one can see a brightening around the entire sun, instead of in just one direction. Material ejected in this event reached the Earth in the night of April 10-11. A significant amount of geomagnetic activity was observed in northern regions all over the world, reaching as far south as New Hampshire and Montana.

THEMIS Mission and Substorm …
Title THEMIS Mission and Substorm Simulation
Abstract This visualization combines simulations of the THEMIS (Time History of Events and Macroscale Interactions during Substorms) mission orbits with a GGCM (Geospace General Circulation Model) simulation. It illustrates how the five THEMIS satellites will work together to detect substorm events in the magnetosphere. One goal of the THEMIS mission is to test how these substorm events are related to the formation of the aurora. This mission consists of five identical spacecraft (usually designated P1, P2, P3, P4 and P5) with orbits aligned so they reach their apogee along the same line from the Earth. This alignment remains fixed in space so as the Earth moves around the Sun, the constellation of spacecraft will extend on the nightside of the Earth in winter to sample the Earth's magnetosphere, and on the dayside of the Earth in summer to sample the incoming solar wind. This way they can better map the geospace environment. Probes P1 and P2 are called the 'outer probes' and P3, 4, and 5 are the 'inner probes'. P3 and P4 share the same orbit. The outer probes will detect the onset of the substorm, while the inner probes will monitor the Earthward plasma flows from the event.

Digital Data Matrix Scanner …
Name of Image Digital Data Matrix Scanner Developnent At Marshall Space Flight Center
Date of Image 2004-01-08
Full Description Research at NASA's Marshall Space Flight Center has resulted in a system for reading hidden identification codes using a hand-held magnetic scanner. It's an invention that could help businesses improve inventory management, enhance safety, improve security, and aid in recall efforts if defects are discovered. Two-dimensional Data Matrix symbols consisting of letters and numbers permanently etched on items for identification and resembling a small checkerboard pattern are more efficient and reliable than traditional bar codes, and can store up to 100 times more information. A team led by Fred Schramm of the Marshall Center's Technology Transfer Department, in partnership with PRI,Torrance, California, has developed a hand-held device that can read this special type of coded symbols, even if covered by up to six layers of paint. Before this new technology was available, matrix symbols were read with optical scanners, and only if the codes were visible. This latest improvement in digital Data Matrix technologies offers greater flexibility for businesses and industries already using the marking system. Paint, inks, and pastes containing magnetic properties are applied in matrix symbol patterns to objects with two-dimensional codes, and the codes are read by a magnetic scanner, even after being covered with paint or other coatings. The ability to read hidden matrix symbols promises a wide range of benefits in a number of fields, including airlines, electronics, healthcare, and the automotive industry. Many industries would like to hide information on a part, so it can be read only by the party who put it there. For instance, the automotive industry uses direct parts marking for inventory control, but for aesthetic purposes the marks often need to be invisible. Symbols have been applied to a variety of materials, including metal, plastic, glass, paper, fabric and foam, on everything from electronic parts to pharmaceuticals to livestock. The portability of the hand-held scanner makes work faster and easier. It reads marks in darkness, under bright light that might interfere with optical reading of visible marks, and can detect symbols obscured by discoloration or contamination. Through a license with NASA, another partner, Robotic Vision Systems, Inc., of Nashua, New Hampshire, will sell the scanner on the commercial market. NASA continues to seek additional companies to license the product. Joint efforts by Marshall researchers and industry partners are aimed at improving dentification technology as part of NASA's program to better life on Earth through technology designed for the space program.

Suncook River Shifts Course
Title Suncook River Shifts Course
Description In mid-May 2006, the U.S. Northeast experienced days of heavy rain. Several states declared a state of emergency as floods strained dams and forced people to evacuate. Near the New Hampshire town of Epsom, the flooding Suncook River abandoned its meandering course around Bear Island and carved a more direct course southwest, the most dramatic change in a New Hampshire river course in recorded history. This image of the old and new channels was captured by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) [ http://asterweb.jpl.nasa.gov ] sensor on NASA's Terra [ http://terra.nasa.gov ] satellite. The bottom image shows a regional perspective, including the city of Concord. A white box outlines the Suncook River close-up view (top). Because narrow rivers can be hard to distinguish from dense vegetation in photo-like satellite images, this image uses ASTER's observations of shortwave and near-infrared light to make water (blue) and bare ground (gray) stand out from vegetation (red). Before the floods, the Suncook River flowed southward around Bear Island in two streams that joined up again to the west of Round Pond. During the flood, the river rushed past the old bend in the river and plowed its way more directly southwest, abandoning the riverbeds around the west and northeast sides of Bear Island. On either side of the river at the point where the new channel starts, charcoal-colored patches show where the land was scoured. The state is studying the event and trying to determine what the impacts will be on fish and other river life, as the stretch of river was a popular angling spot. In addition, owners of former riverside restaurants, campgrounds, and other tourist spots hope the state will try to divert the river back into its former bed. Geologists and engineers are studying the change and trying to determine what, if anything, should be done about the river's new path.

A Lenticular Cloud Over New …
Title A Lenticular Cloud Over New Hampshire
Explanation Why does this cloud look so strange? Actually, pictured above are several clouds [ http://seaborg.nmu.edu/Clouds/types.html ] all stacked up into one striking lenticular cloud [ http://sa1.star.uclan.ac.uk/~prn/lenticular/clouds.html ]. Normally, air moves much more horizontally than it does vertically. Sometimes, however, such as when wind comes off of a mountain [ http://antwrp.gsfc.nasa.gov/apod/ap020723.html ] or a hill [ http://antwrp.gsfc.nasa.gov/apod/ap030416.html ], relatively strong vertical oscillations take place as the air stabilizes. The dry air at the top of an oscillation [ http://snrs.unl.edu/amet351/noehrenberg/lenticularclouds.html ] may be quite stratified in moisture content, and hence forms clouds [ http://www.stemnet.nf.ca/CITE/cloudsform.htm ] at each layer where the air saturates with moisture. The result can be a lenticular cloud [ http://antwrp.gsfc.nasa.gov/apod/ap030326.html ] with a strongly layered appearance. The above picture [ http://vortex.plymouth.edu/lenticular1.html ] was taken in 1999 over Plymouth, New Hampshire [ http://www.state.nh.us/ ], USA [ http://www.cia.gov/cia/publications/factbook/geos/us.html ]. The same lenticular cloud [ http://vortex.plymouth.edu/clouds.html ] also looks strange when photographed from 30 kilometers away [ http://vortex.plymouth.edu/lenticular2.html ].
A Hale-Bopp Triple Crown
Title A Hale-Bopp Triple Crown
Explanation It was truly a busy sky. In one of the more spectacular photos yet submitted to Astronomy Picture of the Day [ http://www.phy.mtu.edu/apod/ ], Don Cooke of Lyme, New Hampshire [ http://www.state.nh.us/soiccnh/lyme.htm ] caught the Sun [ http://www.seds.org/nineplanets/nineplanets/sol.html ], Moon [ http://antwrp.gsfc.nasa.gov/apod/lib/moon.html ], Earth [ http://antwrp.gsfc.nasa.gov/apod/ap970130.html ], night sky [ http://antwrp.gsfc.nasa.gov/apod/ap970403.html ], Pleiades star cluster [ http://antwrp.gsfc.nasa.gov/apod/ap960903.html ], and Comet Hale-Bopp [ http://www.jpl.nasa.gov/comet/ ] all in one frame. The first leg of this "triple crown" exposure was of the Sun [ http://antwrp.gsfc.nasa.gov/apod/ap960518.html ], taken at 6:55 pm on April 10th 1997. Through a dark filter, the Sun [ http://antwrp.gsfc.nasa.gov/apod/lib/sun.html ] appears as the bright dot on the lower right of the image. A second filtered exposure was then taken after the Sun had set, one hour and 40 minutes later - this time featuring the Moon [ http://nssdc.gsfc.nasa.gov/photo_gallery/photogallery-moon.html ]. The Moon appears as a crescent superimposed on an odd-shaped dark circle protruding into the left of the image. This shadow is actually a silhouette of a driveway reflector mounted on an aluminum rod used to block out the bright moon - so as to allow a third exposure, this time unfiltered, of the background night sky. And what a beautiful sky it is. Highlights include Comet Hale-Bopp [ http://antwrp.gsfc.nasa.gov/apod/ap970610.html ], on the right, and the Pleiades star cluster [ http://www.seds.org/billa/twn/m45x.html ], near the center. But what, you may wonder, is that bright light near the center of the picture? Don't worry if you can't guess: it's a porch light from a house across the river!

Title Alan B. Shepard Jr. 1923-1998
Explanation On another Friday (May 5, 1961), at the dawn of the space age [ http://www.hq.nasa.gov/office/pao/History/sputnik/index.html ], NASA controllers "lit the candle" and sent Alan B. Shepard Jr. arcing into space atop a Redstone rocket [ http://antwrp.gsfc.nasa.gov/apod/ap980404.html ]. The picture shows the pressure-suited Shepard before the launch in his cramped space capsule [ http://images.jsc.nasa.gov/images/pao/MERC_OV/10073402.htm ] dubbed "Freedom 7" [ http://images.jsc.nasa.gov/images/pao/MR3/10073523.htm ]. This historic flight [ http://www.ksc.nasa.gov/history/mercury/mr-3/mr-3.html ] - the first spaceflight by an American - made Shepard a national hero [ http://www.nasm.edu/GALLERIES/GAL114/SpaceRace/ ]. Born in East Derry, New Hampshire on November 18, 1923, Shepard graduated from the United States Naval Academy in 1944 and went on to train and serve as a Naval Aviator. Chosen as one of the original seven Mercury Program [ http://www.hq.nasa.gov/office/pao/History/SP-4201/toc.htm ] astronauts, he considered this first flight [ http://www.hq.nasa.gov/office/pao/History/SP-4201/ch11-4.htm ] the greatest challenge and actively sought the assignment. Shepard's accomplishments in his career as an astronaut spanned a remarkable period in human achievement and in 1972 he walked on the moon [ http://www.hq.nasa.gov/office/pao/History/alsj/ ] as commander of the Apollo 14 mission. A true pioneer and intrepid explorer, Alan Shepard died Tuesday [ http://www.nasa.gov/shepard.html ] at age 74 after a lengthy illness.

Title Summer Turns to Autumn in New England
Original Caption Released with Image The green hues of summer give way to the reds and browns of autumn in this pair of MISR nadir-camera views acquired on August 26, 2000 (left) and October 20, 2000 (right). The images include eastern Vermont, New Hampshire, and western Maine, as well as the southeastern corner of Quebec province. New Hampshire's White Mountains run roughly north-south through the center of each image. Linear patterns associated with forest clear cuts are apparent in the upper left quadrant of the images. Some scattered cumulus clouds are present, and urban centers show up as patches of gray. The city of Portland, Maine, is at the lower right corner, to the southeast of Sebago Lake. Sherbooke, Quebec, is visible to the northeast of Lake Memphremagog, which straddles the US-Canadian border. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, MD. JPL is a division of the California Institute of Technology.

Title Smoke Signals from the Alaska and Yukon Fires
Original Caption Released with Image . Some of the smoke from these fires was detected as far away as New Hampshire. These visualizations were captured on June 30th by the Multi-angle Imaging SpectroRadiometer (MISR) on NASA's Terra spacecraft. Here, MISR distinguishes clouds from smoke and retrieves heights and optical depths for the smoke -- information which will help to improve models of how smoke aerosols are transported. The images cover an area extending from the Mackenzie Bay in northwest Canada, through the Alaskan Interior and along the Alaska-Yukon border, south to the Wrangell Mountains. The first panel in the series is a natural-color image from MISR's 60° forward viewing camera. Smoke plumes notable along the right-hand edge are situated southwest of the Peel River in the Yukon Territory, and plumes extending west from the left-hand edge are situated in the vicinity of the Yukon River and the town of Eagle at the Alaska-Canada border. In the lower portion of the image, thick smoke obscures the Wrangell Mountain range. The next panel in the series is a stereoscopic height field, in which topography, smoke plumes and clouds are all being detected. Analysis indicates that most of the smoke and many low clouds are situated at heights between about 1 and 4 kilometers above the surface, while a few high clouds attained much greater altitudes. The third panel from the left is a smoke mask, in which the image is classified as either non-smoke, or as smoke with low confidence (lc) or high confidence (hc), represented by the blue, red and green pixels, respectively. Many of the actual smoke "plumes" were identified as high-confidence smoke, including parts of plumes in the Peel River region (upper right) and Yukon River/Alaska-Canada border region (left-hand edge). This smoke mask is produced by a computerized "machine-learning" classifier which detects smoke by examining the spectral, textural, and angular features in the radiances from three oblique-viewing MISR cameras. Ultimately, the classifier will be trained to identify plume-like shapes, thus making it possible to automatically isolate plume heights from the stereo product. The right-hand panel displays MISR's aerosol optical depth retrieval, in which the brightness and contrast changes of the surface at different view angles are used to measure the attenuation of sunlight as it passes through a column of the atmosphere. Increasing amounts of smoke aerosol appear as green, yellow, orange and red pixels, and clearer skies are indicated by blue pixels. Areas where the aerosol optical depth could not be retrieved, either because the smoke was too thick to see the surface contrast or because the presence of clouds precluded a retrieval, are shown in dark gray. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuously and every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. The non-animated data products were generated from a portion of the imagery acquired, Large lightning-induced fires were active in Alaska and the Yukon Territory from mid-June to mid-July, 2004. Thick smoke particles filled the air during these fires, prompting Alaskan officials to issue air quality warnings [ http://airnow.gov/ ], during Terra orbits 24123. The still panels cover an area of about 400 kilometers 898 kilometers, and use data from blocks 35 to 41 within World Reference System-2 path 64. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, Calif., for NASA's Office of Earth Science, Washington, DC. The Terra satellite is managed by NASA's Goddard Space Flight Center, Greenbelt, Md. JPL is a division of the California Institute of Technology.

Title New England from Boston to Lake Champlain and up to southern Main from STS-58
Description This photograph includes much of the heart of New England, stretching from Boston and Boston Harbor (lower left) across New Hampshire and Vermont to Lake Champlain (upper left), and up to southern Maine (Portland is just off the photo at right center). North of Boston flows the Merrimack River (which forms part of the state boundary between Massachuesetts and New Hampshire). It is delineated by the small industrial towns (Concord, Manchester, Nashua, Lowell) which grew up on its banks. The White Mountains of New Hampshire are seen near the center, and Mt. Washington (6,288 feet) is capped with snow. Fort Sam Houston is contained within the northeast quadrant of the city, Brooks Air Force Base lies at the southeastern corner, and Lackland and Kelly Air Force Bases are within the suburban fringe to the southwest. San Antonio International Airport can be seen at the foot of the escarpment in the northern part of the city.
