| Description |
Australia's capital city, Canberra, is shown in the center of this spaceborne radar image. Images like this can help urban planners assess land use patterns. Heavily developed areas appear in bright patchwork patterns of orange, yellow and blue. Dense vegetation appears bright green, while cleared areas appear in dark blue or black. Located in southeastern Australia, the site of Canberra was selected as the capital in 1901 as a geographic compromise between Sydney and Melbourne. Design and construction of the city began in 1908 under the supervision of American architect Walter Burley-Griffin. Lake Burley-Griffin is located above and to the left of the center of the image. The bright pink area is the Parliament House. The city streets, lined with government buildings, radiate like spokes from the Parliament House. The bright purple cross in the lower left corner of the image is a reflection from one of the large dish-shaped radio antennas at the Tidbinbilla, Canberra Deep Space Network Communication Complex, operated jointly by NASA and the Australian Space Office. This image was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR- C/X-SAR) on April 10, 1994, onboard the space shuttle Endeavour. The image is 28 kilometers by 25 kilometers (17 miles by 15 miles) and is centered at 35.35 degrees south latitude, 149.17 degrees east longitude. North is toward the upper left. The colors are assigned to different radar frequencies and polarizations as follows: red is L-band, horizontally transmitted and received, green is L-band, horizontally transmitted and vertically received, and blue is C-band, horizontally transmitted and vertically received. SIR-C/X-SAR, a joint mission of the German, Italian, and United States space agencies, is part of NASA's Office of Mission to Planet Earth. ##### |

Deep Space Network |
| description |
The NASA Deep Space Network - or DSN - is an international network of antennas that supports interplanetary spacecraft missions and radio and radar astronomy observations for the exploration of the solar system and the universe. The network also supports selected Earth-orbiting missions. The DSN currently consists of three deep-space communications facilities placed approximately 120 degrees apart around the world: at Goldstone, in California's Mojave Desert, near Madrid, Spain, and near Canberra, Australia. This strategic placement permits constant observation of spacecraft as the Earth rotates, and helps to make the DSN the largest and most sensitive scientific telecommunications system in the world. NASA's scientific investigation of the Solar System is being accomplished mainly through the use of unmanned automated spacecraft. The DSN provides the vital two-way communications link that guides and controls these planetary explorers, and brings back the images and new scientific information they collect. All DSN antennas are steerable, high-gain, parabolic reflector antennas. The network is managed and operated for NASA by the Jet Propulsion Laboratory. The Interplanetary Network Directorate (IND) manages the program within JPL. For more on the Deep Space Network, visit http://deepspace.jpl.nasa.gov/dsn/index.html *Image Credit*: NASA |

Bushfires Raging in Southeast Australia |
| Description |
In southeastern Australia, bushfires are raging out of control. At the border of southeast New South Wales and northeast Victoria in the Great Dividing Range Mountains, dozens of out-of-control fires have destroyed at least 400 homes and killed four people according to local news reports from Tuesday, January 21. The fires blazed through portions of Australia?s capital city of Canberra in the Australian Capital Territory (ACT) along corridors of natural bush that are mixed with the urban landscape. Among the devastating losses, more than two dozen farms have been destroyed and hundreds of livestock have perished. Many farmers are being forced to rapidly sell remaining livestock as the fires have destroyed all available pasture. This true-color Moderate Resolution Imaging Spectroradiometer (MODIS) image from the Terra satellite on January 19, 2003, shows the numerous bushfires marked with red dots, as well as the thick, choking smoke. The ACT is almost completely shrouded in smoke from the densest concentrations of fires (left of center). Fires are also burning northwest of Sydney (top center). Conditions are expected to worsen as the week progresses, with high temperatures and winds up to 65 knots (71 miles per hour) whipping the blazes further out of control. More than 900 firefighters are battling the fires, and more continue to pour in from surrounding territories to lend a hand. The high-resolution image available here is 500 meters per pixel. Visit the MODIS Rapid Response Team, for a copy of this scene at MODIS? full resolution of 250 meters per pixel. Image courtesy Jacques Descloitres, MODIS Rapid Response Team, NASA GSFC |

Bushfires Raging in Southeast Australia |
| Description |
Ribbons of flame trace across the parched landscape of southeast Australia. Prolonged, severe drought (exacerbated by an El Ni¤o), high winds, and high temperatures have sparked scores of fires across New South Wales and Victoria, Australia. Lives, homes, farmland, and livestock have been lost to the blazes. This scene, situated roughly 30 km southwest of Canberra, shows smoke billowing from one of the numerous fires in the region. This unusual image was made from data collected on January 26, 2003, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on the Terra satellite. The image is a combination of radiation in the visible and shortwave infrared parts of the electromagnetic spectrum, using ASTER bands 3, 2, and 1. Fires burning in vegetation tend to emit radiation very strongly in the short wave infrared wavelengths of radiation, and this strong signal can be used to locate areas of open flame. In this image, the strong shortwave infrared signal of the flames has been colored bright yellow. Vegetation is red, and naturally bare soil is tan. The full scene is roughly 40 km by 60 km in area.

Severe Thunderstorms Across Southeastern Australia |
| Description |
Severe thunderstorms deluged southeastern Australia with heavy rain and isolated hail on December 3, 2003. Six people were hospitalized after being struck by lightning. The storms had been developing for several days, and culminated on December 3. High pressure off of the east coast of Australia pumped warm humid air southward from the tropics ahead of an advancing cold front, a scenario favorable for thunderstorm development. The TRMM-based, near-real time Multi-satellite Precipitation Analysis (MPA) at the NASA Goddard Space Flight Center shows rainfall totals between November 29 and December 3. One to three inches of rain fell over a widespread area from western New South Wales inland to near Melbourne and Canberra along the southeast coast (green areas). Locally heavier amounts are shown north-northwest of Melbourne in red. Clusters of white dots show where the TRMM Lightning Imaging Sensor (LIS) dectected lightning activity in a single overpass on December 3. LIS saw multiple flashes, including cloud-to-cloud, cloud-to-ground, and intracloud flashes in what amounts to a quick snapshot. TRMM is a joint mission between NASA and the Japanese space agency NASDA. Image produced by Hal Pierce (SSAI/NASA GSFC) and caption by Steve Lang (SSAI/NASA GSFC) |

The Regolith of Asteroid Ero
…
| Title |
The Regolith of Asteroid Eros |
| Explanation |
From fifty kilometers above asteroid Eros, the surface inside one of its largest craters appears covered with an unusual substance: regolith [ http://science.canberra.edu.au/rcentres/cars/regolith.html ]. The thickness and composition of the surface dust that is regolith [ http://adsabs.harvard.edu/cgi-bin/nph-bib_query?bibcode=1998DPS....30.0703C ] remains a topic of much research. Much of the regolith on 433 Eros [ http://near.jhuapl.edu/eros/sum.html ] was probably created by numerous small impacts during its long history. In this representative-color view [ http://near.jhuapl.edu/NEAR/iod/20000707/index.html ] taken by the robot spacecraft NEAR-SHOEMAKER [ http://near.jhuapl.edu/spacecraft/ ] that orbited Eros [ http://near.jhuapl.edu/intro/faq.html ] in 2000 and 2001, brown areas indicate regolith [ http://near.jhuapl.edu/iod/20000713/ ] that has been chemically altered by exposure to the solar wind [ http://antwrp.gsfc.nasa.gov/apod/ap000318.html ] during micrometeorite [ http://www.solarviews.com/eng/edu/micromet.htm ] impacts. White areas are thought to have undergone relatively less exposure. The boulders visible [ http://antwrp.gsfc.nasa.gov/apod/ap000824.html ] inside the crater appear brown, indicating either that they are old enough to have a surface itself tanned by the solar wind [ http://www-istp.gsfc.nasa.gov/Education/wsolwind.html ], or that they have somehow become covered with some dark surface regolith [ http://antwrp.gsfc.nasa.gov/apod/ap011110.html ]. |

B-57B in flight |
| Description |
This is a photograph of the Martin B-57 Canberra light bomber in flight. The aircraft has a bare-metal finish. The "V" insignia is from its use in the Viking Mars Lander parachute test program. In the early 1970s, a Martin B-57B Canberra light bomber was used in several NASA joint flight test programs at the NASA Flight Research Center (now Dryden Flight Research Center) located at Edwards Air Force Base, California. The early 1970s showed a growing interest in continuing atmospheric research. The B-57B was at the NASA Flight Research Center for a joint program with NASA Langley Research Center, Hampton, Virginia and was having a special set of instrumentation installed. Delays in completing the instruments provided an opportunity to support the NASA space program. The B-57B was used in proof-of-concept testing of the Viking Mars landers. The deceleration drop testing part of the program took place at the Joint Parachute Test Facility, El Centro, California. With completion of the Viking parachute tests, the B-57B was flown for measuring and analysis of atmospheric turbulence research in 1974-75 as part of a joint NASA program between the Flight Research Center and Langley Research Center. Additional atmospheric testing provided samples of aerosols for the University of Wyoming and clear-air turbulence data for the Department of Transportation. The aircraft was tested over a span of many years at Edwards Air Force Base by various NASA centers for other types of research. Earlier, in the 1960s, the aircraft was flown at the Flight Research Center by the Lewis Research Center (now the John Glenn Research Center) in support of the newly established NASA Electronics Center in Boston, Massachusetts. Later, in 1982, the B-57B aircraft returned to the Flight Research Center (then the Ames-Dryden Flight Research Facility) for more Langley-sponsored turbulence testing. The atmospheric research conducted using the B-57B Canberra provided information on mountain waves, jet streams, convective turbulence, and clear-air turbulence. |

| Description |
A converted Martin B-57B Canberra medium bomber sits on the ramp at the NASA Ames-Dryden Flight Research Facility, Edwards, California. The rugged NASA aircraft was flown by Dryden in the early 1970s to learn more about the atmosphere. Instrumented with a data acquisition system, Dryden pilots measured atmospheric conditions and clear-air turbulence at various altitudes and sampled the upper atmosphere for various aerosols. The research - to give scientists a better understanding of mountain waves, jet streams, convective turbulence, clear-air turbulence, and atmospheric contaminants - was sponsored by NASA's Langley Research Center, the University of Wyoming, and the Department of Transportation. The aircraft was retired from flight status in 1987. In the early 1970s, a Martin B-57B Canberra light bomber was used in several NASA joint flight test programs at the NASA Flight Research Center (now Dryden Flight Research Center) located at Edwards Air Force Base, California.

Venus - Crater Golubkina
| Title |
Venus - Crater Golubkina |
| Description |
This Magellan image mosaic shows the impact crater Golubkina, first identified in Soviet Venera 15/16 data. The crater is named after Anna Golubkina (1864-1927), a Soviet sculptor. The crater is about 34 kilometers (20.4 miles) across, similar to the size of the West Clearwater impact structure in Canada. The crater Golubkina is located at about 60.5 degrees north latitude, 286.7 degrees east longitude. Magellan data reveal that Golubkina has many characteristics typical of craters formed by a meteorite impact including terraced inner walls, a central peak, and radar bright rough ejecta surrounding the crater. The extreme darkness of the crater floor indicates a smooth surface, perhaps formed by the pounding of lava flows in the crater floor as seen in many lunar impact craters. The radar bright ejecta surrounding the crater indicates a relatively fresh or young crater. Craters with central peaks in the Soviet data range in size from about 10.60 km (6.36 miles) across. The largest crater identified in the Soviet Venera data is 140 km (84 miles) in diameter. This Magellan image strip is approximately 20 km (12 miles) wide and this piece of the image is approximately 100 km (62 miles) long. The image is a mosaic of two orbits obtained in the first Magellan radar test and played back to Earth to the Deep Space Network stations near Goldstone, Calif. and Canberra, Australia, respectively. The resolution of this image is approximately 120 meters (400 feet). The see-saw margins result from the offset of individual radar frames obtained along the orbit. The spacecraft moved from the north (top) to the south, looking to the left. |

| Title |
Fires in the Australian Capital Territory |
| Original Caption Released with Image |
The height and extent of billowing smoke plumes from bushfires near Canberra, the Australian capital, are illustrated by these views from the Multi-angle Imaging SpectroRadiometer (MISR). The images were acquired on January 18, 2003. Never before had fires of this magnitude come so close to Australia's capital. Four people lost their lives and over 500 homes were destroyed, mostly in the southwestern suburbs. Australia's famous Mount Stromlo Observatory, located immediately west of the city, was also incinerated by the fires. The top panel portrays a natural-color view from MISR's nadir camera, in which the eastern portion of the Australian Capital Territory is located south of a pale, ephemeral lake in the upper left-hand corner (Lake George). Several smoke plumes originate within the eastern part of the Australian Capital Territory, while the major plumes originate to the west of the image area. The Australian Capital Territory and much of New South Wales are completely obscured by the smoke, which is driven by fierce westerly winds and extends eastward to the coast and over the Pacific Ocean. The lower panel provides a stereoscopically retrieved height field of the clouds and smoke plumes. The greenish areas indicate where smoke plumes extend several kilometers above a bank of patchy stratus clouds below. A few high clouds appear near the bottom of the image. Wind retrievals were excluded from this image in order to generate a smooth and continuous field. Although relative height variations are well-represented here, the inclusion of wind retrievals for this scene reduces the actual cloud height results by 1 to 2 kilometers. Areas where heights could not be retrieved are shown as dark gray. The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuouslyand every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. This data product was generated from a portion of the imagery acquired during Terra orbit 16421. The panels cover an area of 380 kilometers x 253 kilometers, and utilize data from blocks 118 to 120 within World Reference System-2 path 89.

Venus - First Radar Test |
| Original Caption Released with Image |
After traveling more than 1.5 billion kilometers (948 million miles), the Magellan spacecraft was inserted into orbit around Venus on Aug. 10, 1990. This mosaic consists of adjacent pieces of two Magellan image strips obtained on Aug. 16 in the first radar test. The radar test was part of a planned In Orbit Checkout sequence designed to prepare the Magellan spacecraft and radar to begin mapping after Aug. 31. The strip on the left was returned to the Goldstone Deep Space Network station in California, the strip to the right was received at the DSN in Canberra, Australia. A third station that will be receiving Magellan data is located near Madrid, Spain. Each image strip is 20 km (12 miles) wide and 16,000 km (10,000 miles) long. This mosaic is a small portion 80 km (50 miles) long. This image is centered at 21 degrees north latitude and 286.8 degrees east longitude, southeast of a volcanic highland region called Beta Regio. The resolution of the image is about 120 meters (400 feet), 10 times better than previous images of the same area of Venus, revealing many new geologic features. The bright line trending northwest southeast across the center of the image is a fracture or fault zone cutting the volcanic plains. In the upper left corner of the image, a multiple ring circular feature of probable volcanic origin can be seen, approximately 4.27 km (2.65 miles) across. The bright and dark variations seen in the plains surrounding these features correspond to volcanic lava flows of varying ages. The volcanic lava flows in the southern half of the image have been cut by north south trending faults. This area is similar geologically to volcanic deposits seen on Earth at Hawaii and the Snake River Plains in Idaho. |

| Title |
Venus - Rhea Mons Volcano |
| Original Caption Released with Image |
Two mosaiced pieces of Magellan image strips display the area east of the Rhea Mons volcano on Venus. This image is centered at about 32.5 degrees north latitude and 286.6 degrees east longitude. The mosaic is 47 kilometers (28 miles) wide and 135 km (81 miles) long. This region has been previously identified as "tessera" from Earth-based radar (Arecibo) images. The center of the image is dominated by a network of intersecting ridges and valleys. The radar bright north south trending features in this image range from 1 km (0.6 mile) to 3 km (1.8 miles) in length. The average spacing between these ridges is about 1.5 km (0.9 mile). The dark patches at the top of the image are smooth surfaces and may be lava flows located in lowlands between the higher ridge and the valley terrain. This image is a mosaic of two orbits obtained in the first Magellan radar test and played back to Earth to the Deep Space Network stations near Goldstone, Calif. and Canberra, Australia, respectively. The resolution of this image is approximately 120 meters (400 feet). |

| Title |
Venus - Crater Golubkina |
| Original Caption Released with Image |
This Magellan image mosaic shows the impact crater Golubkina, first identified in Soviet Venera 15/16 data. The crater is named after Anna Golubkina (1864-1927), a Soviet sculptor. The crater is about 34 kilometers (20.4 miles) across, similar to the size of the West Clearwater impact structure in Canada. The crater Golubkina is located at about 60.5 degrees north latitude, 286.7 degrees east longitude. Magellan data reveal that Golubkina has many characteristics typical of craters formed by a meteorite impact including terraced inner walls, a central peak, and radar bright rough ejecta surrounding the crater. The extreme darkness of the crater floor indicates a smooth surface, perhaps formed by the pounding of lava flows in the crater floor as seen in many lunar impact craters. The radar bright ejecta surrounding the crater indicates a relatively fresh or young crater. Craters with central peaks in the Soviet data range in size from about 10.60 km (6.36 miles) across. The largest crater identified in the Soviet Venera data is 140 km (84 miles) in diameter. This Magellan image strip is approximately 20 km (12 miles) wide and this piece of the image is approximately 100 km (62 miles) long. The image is a mosaic of two orbits obtained in the first Magellan radar test and played back to Earth to the Deep Space Network stations near Goldstone, Calif. and Canberra, Australia, respectively. The resolution of this image is approximately 120 meters (400 feet). The see-saw margins result from the offset of individual radar frames obtained along the orbit. The spacecraft moved from the north (top) to the south, looking to the left. |
