Project Red Socks

title	Project Red Socks
date	10.01.1957
description	Project RED SOCKS was to be "the world's first useful moon rocket," proposed by the Jet Propulsion Laboratory/California Institute of Technology in October 1957. These artist's renditions show the configuration of motors and a diagram of the moon orbit. RED SOCKS was to respond to the Sputnik launch challenge with a significant technological advance over the Soviet Union instead of merely matching them with another earth-orbiting satellite. The objectives of the project were to "1) get photos, 2) refine space guidance techniques, and 3) impress the world" with a series of nine rocket flights to the moon. The second of the nine flights was to take pictures of the back of the moon. The necessary technology had already been developed for earlier projects, such as the Re-entry Test Vehicle and the Microlock radio ground tracking system. Project RED SOCKS received no support in Washington. In December 1957, JPL and the Army Ballistic Missile Agency (ABMA) were instead asked to orbit an Earth satellite. Explorer 1 was launched 81 days later, on January 29, 1958. A modified RED SOCKS plan was carried out in the Pioneer 4 project in March 1959. Image Credit: NASA Jet Propulsion Laboratory

COBE's View of the Milky Way

title	COBE's View of the Milky Way
date	01.01.1990
description	From its orbit around Earth, the Goddard Space Flight Center's Cosmic Background Explorer (COBE) captured this edge-on view of our Milky Way galaxy in infrared light, a form of radiation that humans cannot see but can feel in the form of heat, as part of its mission to test the "Big Bang" theory of the creation of the universe. The theory, first proposed in 1927 by Belgian cosmologist Georges Lematre, holds that the universe began as an incredibly dense "primeval atom" that exploded with tremendous force, unleashing matter and space at the speeds of light. NASA set out to prove the theory with the help of COBE. In addition to proving the Big Bang, the satellite discovered that the cosmic background radiation had indeed been produced in the Big Bang just as scientists originally speculated. The satellite's data even discovered the primordial temperature and density fluctuations that eventually gave rise to the Milky Way and other large-scale objects found in space today.

Nanorover

title	Nanorover
description	This prototype Nanorover is only 20 cm (8 inches) long. One possible use for this type of miniature explorer is to send back information from the surface of an asteroid to an orbiting spacecraft. The rover's camera can be focused to take panoramic shots as well as microscopic images. Solar cells will be placed on all sides of the rover so that even if it flips over on an asteroid's low-gravity surface, the rover will always have enough power to activate motors that will allow it to right itself. Wheel struts will allow the rover to position its chassis such that the camera can be pointed straight down at the surface or straight up at the sky.

Title	Galaxy Mission Completes Four Star-Studded Years in Space
Original Caption Released with Image	NASA's Galaxy Evolution Explorer is celebrating its fourth year in space with some of M81's "hottest" stars. In a new ultraviolet image, the magnificent M81 spiral galaxy is shown at the center. The orbiting observatory spies the galaxy's "sizzling young starlets" as wisps of bluish-white swirling around a central golden glow. The tints of gold at M81's center come from a "senior citizen" population of smoldering stars. "This is a spectacular view of M81," says Dr. John Huchra, of the Harvard Smithsonian Center for Astrophysics, Cambridge, Mass. "When we proposed to observe this galaxy with GALEX we hoped to see globular clusters, open clusters, and young stars...this view is everything that we were hoping for." The image is one of thousands gathered so far by GALEX, which launched April 28, 2003. This mission uses ultraviolet wavelengths to measure the history of star formation 80 percent of the way back to the Big Bang. The large fluffy bluish-white material to the left of M81 is a neighboring galaxy called Holmberg IX. This galaxy is practically invisible to the naked human eye. However, it is illuminated brilliantly in GALEX's wide ultraviolet eyes. Its ultraviolet colors show that it is actively forming young stars. The bluish-white fuzz in the space surrounding M81 and Holmberg IX is new star formation triggered by gravitational interactions between the two galaxies. Huchra notes that the active star formation in Holmberg IX is a surprise, and says that more research needs to be done in light of the new findings from GALEX. "Some astronomers suspect that the galaxy Holmberg IX is the result of a galactic interaction between M81 and another neighboring galaxy M82," says Huchra. "This particular galaxy is especially important because there are a lot of galaxies like Holmberg IX around our Milky Way galaxy. By understanding how Holmberg IX came to be, we hope to understand how all the little galaxies surrounding the Milky Way developed.""Four years after GALEX's launch, the spacecraft is performing magnificently. The mission results have been simply amazing as it helps us to unlock the secrets of galaxies, the building blocks of our universe," says Kerry Erickson, GALEX project manager. M81 and Holberg IX are located approximately 12 million light-years away in the northern constellation Ursa Major. In addition to leading the GALEX observations of M81, Huchra and his team also took observations of the region with NASA's Spitzer and Hubble space telescopes. By combining all these views of M81, Huchra hopes to gain a better understanding about how M81 has developed into the spiral galaxy we see today. The California Institute of Technology in Pasadena, Calif., leads the Galaxy Evolution Explorer mission and is responsible for science operations and data analysis. NASA's Jet Propulsion Laboratory, also in Pasadena, manages the mission and built the science instrument. The mission was developed under NASA's Explorers Program, managed by the Goddard Space Flight Center, Greenbelt, Md. Researchers from South Korea and France collaborated on this mission.

James Ross Island captured by NASA photographer James Ross(no relation), from NASA's DC-8 aircraft during an AirSAR 2004 mission over the Antarctic Peninsula. James Ross Island, named for 19th century British polar explorer Sir James Clark Ross, is located at the northern tip of the Antarctic Peninsula. The island is about 1500 m high and 40-60 km wide. In recent decades, the area has experienced significant atmospheric warming (about 2 degrees C since 1950), which has triggered a vast and spectacular retreat of its floating ice shelves, glacier reduction, a decrease in permanent snow cover and a lengthening of the melt season. AirSAR 2004 is a three-week expedition in Central and South America by an international team of scientists that is using an all-weather imaging tool, called the Airborne Synthetic Aperture Radar (AirSAR), located onboard NASA's DC-8 airborne laboratory. Scientists from many parts of the world are combining ground research with NASA's AirSAR technology to improve and expand on the quality of research they are able to conduct. These photos are from the DC-8 aircraft while flying an AirSAR mission over Antarctica. The Antarctic Peninsula is more similar to Alaska and Patagonia than to the rest of the Antarctic continent. It is drained by fast glaciers, receives abundant precipitation, and melts significantly in the summer months. This region is being studied by NASA using a DC-8 equipped with the Airborne Synthetic Aperture Radar developed by scientists from NASA?s Jet Propulsion Laboratory. AirSAR will provide a baseline model and unprecedented mapping of the region. This data will make it possible to determine whether the warming trend is slowing, continuing or accelerating. AirSAR will also provide reliable information on ice shelf thickness to measure the contribution of the glaciers to sea level.

Photo Description	James Ross Island captured by NASA photographer James Ross(no relation), from NASA's DC-8 aircraft during an AirSAR 2004 mission over the Antarctic Peninsula. James Ross Island, named for 19th century British polar explorer Sir James Clark Ross, is located at the northern tip of the Antarctic Peninsula. The island is about 1500 m high and 40-60 km wide. In recent decades, the area has experienced significant atmospheric warming (about 2 degrees C since 1950), which has triggered a vast and spectacular retreat of its floating ice shelves, glacier reduction, a decrease in permanent snow cover and a lengthening of the melt season. AirSAR 2004 is a three-week expedition in Central and South America by an international team of scientists that is using an all-weather imaging tool, called the Airborne Synthetic Aperture Radar (AirSAR), located onboard NASA's DC-8 airborne laboratory. Scientists from many parts of the world are combining ground research with NASA's AirSAR technology to improve and expand on the quality of research they are able to conduct. These photos are from the DC-8 aircraft while flying an AirSAR mission over Antarctica. The Antarctic Peninsula is more similar to Alaska and Patagonia than to the rest of the Antarctic continent. It is drained by fast glaciers, receives abundant precipitation, and melts significantly in the summer months. This region is being studied by NASA using a DC-8 equipped with the Airborne Synthetic Aperture Radar developed by scientists from NASA?s Jet Propulsion Laboratory. AirSAR will provide a baseline model and unprecedented mapping of the region. This data will make it possible to determine whether the warming trend is slowing, continuing or accelerating. AirSAR will also provide reliable information on ice shelf thickness to measure the contribution of the glaciers to sea level.
Project Description	AirSAR collects multi-frequency and multi-polarization radar data for a variety of science applications. It also acquires data in interferometric modes, providing topographic information (cross-track mode) or ocean current information (along-track interferometry). This March 2004 deployment was planned to: * Study the extent and distribution of archeological Mayan civilization (using foliage-penetrating radar) * Study the glaciers of Patagonia and the Antarctic peninsula * Investigate new techniques for the measurement of the forest structure of dense tropical forests * Fill in the largest "void" in the SRTM-derived map of South American topography * Collect additional data for various research initiatives During the deployment data is collected over Central and South America and Antarctica. During the approximately 100 flight hours, AirSAR is acquiring polarimetric and/or interferometric data along a 20,000 km track, or about 200,000 sq. km of data over 40 sites for 30 scientists. AirSAR will collect data related to the following NASA Code YS science programs: * Cryospheric Science * Land Cover/Land Use Change * Natural Hazards * Physical Oceanography * Terrestrial Ecology * Hydrology NASA used a DC-8 aircraft as a flying science laboratory. The platform aircraft, was based at NASA's Dryden Flight Research Center, Edwards, Calif., collected data for many experiments in support of scientific projects serving the world scientific community. Included in this community were NASA, federal, state, academic and foreign investigators. Data gathered by the DC-8 at flight altitude and by remote sensing has been used for scientific studies in archeology, ecology, geography, hydrology, meteorology, oceanography, volcanology, atmospheric chemistry, soil science and biology.

Title	Artist concept of Magellan spacecraft in elliptical orbit around Venus
Description	Magellan spacecraft is shown in elliptical orbit around Venus, collecting data (radar mapping), and then transmitting data back to Earth in this artist concept. When the spacecraft orbit is close to Venus the synthetic aperature radar (SAR) will image a swath between 9 and 15 nautical miles (10 and 17 statute miles) (highlighted in image), beginning at or near the north pole and continuing to the southern hemisphere. Subsequent swaths will slightly overlap and, during its primary mission, the spacecraft will map most of the planet. When the spacecraft moves into the part of its elliptical orbit farthest from Venus, the spacecraft high-gain antenna will be turned toward Earth and will send the data collected during the imaging to Earth. Magellan, named after the 16th century Portuguese explorer, will orbit Venus about once every three hours, acquiring radar data for 37 minutes of each orbit.

Title	Green Summer and Icy Winter in James Bay
Original Caption Released with Image	One year ago, in late February 2000, MISR began acquiring Earth imagery. Its "first light" images showed a frozen James Bay in the Ontario-Quebec region of Canada. These more recent nadir-camera views of the same area illuminate stark contrasts between summer and winter. The left-hand image was acquired on August 9, 2000 (Terra orbit 3427), and the right-hand image is from January 16, 2001 (Terra orbit 5757). James Bay lies at the southern end of Hudson Bay. It is named for the English explorer Thomas James, who first explored the area in 1631 while searching for the Northwest Passage. Visible in these images are some of the many rivers that flow into the bay, starting at the southern tip and moving clockwise on the western side are the Harricana, Moose, Albany, and Attawapiskat. The latter enters the bay just to the west of the large, crescent-shaped Akimiski Island. 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	MISR Sights the Bering Strait
Original Caption Released with Image	With the Seward Peninsula of Alaska to the east, and Chukotskiy Poluostrov of Siberia to the west, the Bering Strait separates the United States and the Russian Federation by only 90 kilometers. It is named for Danish explorer Vitus Bering, who spotted the Alaskan mainland in 1741 while leading an expedition of Russian sailors. This view of the region was captured by MISR's vertical-viewing (nadir) camera on August 18, 2000 during Terra orbit 3562. The boundary between the US and Russia lies between Big and Little Diomede Islands, which are visible in the middle of the Bering Strait. The Arctic Circle, at 66.5 degrees north latitude, runs through the Arctic Ocean in the top part of this image. This circle marks the southernmost latitude for which the Sun does not rise above the horizon on the day of the winter solstice. At the bottom of this image is St. Lawrence Island. Situated in the Bering Sea, it is part of Alaska and home to Yupik Eskimos. MISR was built and is managed by NASA's Jet Propulsion Laboratory, Pasadena, CA, for NASA's Office of Earth Science, Washington, DC.

Title	Grace and Beauty
Original Caption Released with Image	Our robotic explorer Cassini regards the shadow-draped face of Saturn. This view looks toward the unilluminated side of the rings from about 14 degrees above the ringplane. In this viewing geometry all of the main rings, except for the B ring, appear transparent. The rings cast their mirror image onto the planet beyond. Images taken using red, green and blue spectral filters were combined to create this natural color view. The images were acquired with the Cassini spacecraft wide-angle camera on June 9, 2007, at a distance of approximately 1.6 million kilometers (972,000 miles) from Saturn. Image scale is 90 kilometers (56 miles) per pixel. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.
