Description The Interstellar Boundary Explorer (IBEX) mission is a NASA-funded satellite that orbits Earth and maps the boundary of our Solar System from Earth's point of view looking outward. IBEX has completed the first all-sky maps of this boundary by detecting particles traveling inward from the boundary toward our region of the Solar System. The map appears to be oval in shape for the same reason that two-dimensional maps of spherical Earth look oval. The boundary of our Solar System is created by the interaction between charged particles from the Sun that are streaming outward, called the solar wind, and material between the stars, called the interstellar medium (ISM). The solar wind flows outward into space and carves out a protective bubble, called the heliosphere, in the ISM around our Solar System. At the boundary, the interactions between the solar wind particles and the ISM particles create energetic neutral atoms (ENAs). ENAs are particles with no charge that move very fast. Some of the ENAs happen to be traveling in just the right way so that they move inward through the Solar System toward Earth where IBEX can collect them. Using two sensors, called IBEX-Hi and IBEX-Lo, the spacecraft measures and counts these ENAs. The scientists can create maps of the boundary using this information. For each small area of the sky, IBEX has measured the number of ENAs coming from that direction. This map shows the distribution of ENAs ranging in energy from 2.8 to 5.6 keV. Red indicates the highest number of ENAs measured by the spacecraft. Yellow and green indicate lower numbers of ENAs, and blue and purple show the lowest number of ENAs.

Explorer I
Title Explorer I
Explanation Inaugurating the era of space exploration [ http://www.hq.nasa.gov/office/pao/History/SP-4406/contents.html ] for the US, the First Explorer [ http://antwrp.gsfc.nasa.gov/apod/ap970518.html ] was launched [ http://newproducts.jpl.nasa.gov/calander/explorer1.html ] into Earth orbit forty years ago [ http://www.jpl.nasa.gov/releases/98/expl1rel.html ] (February 1, 1958) by the Army Ballistic Missle Agency [ http://www.redstone.army.mil/history/arspace/welcome.html ]. The Explorer I satellite [ http://history.msfc.nasa.gov/history/mm/lk_inst.html ] weighed about 30 pounds, was 6 feet long, 6 inches in diameter and consisted of batteries, transmitters, and scientific instrumentation [ http://www-spof.gsfc.nasa.gov/Education/wexp13.html ] built into the fourth stage of a Jupiter-C rocket. Foreshadowing NASA and the adventurous [ http://www.osf.hq.nasa.gov/history/explorer.html ] and successful Explorer Program [ http://msl.jpl.nasa.gov/Programs/explorer.html ], Explorer I bolstered national prestige in the wake of Sputnik [ http://antwrp.gsfc.nasa.gov/apod/ap970427.html ]. The satellite also contributed to a spectacular scientific bonanza - the discovery of Earth-girdling belts of magnetically trapped charged particles now known as the Van Allen Radiation Belts [ http://www-spof.gsfc.nasa.gov/Education/Iradbelt.html ].

The First Explorer
Title The First Explorer
Explanation The first US spacecraft was Explorer 1 [ http://history.msfc.nasa.gov/history/mm/sect001.html#Explorer I ]. The cylindrical 30 pound satellite [ http://antwrp.gsfc.nasa.gov/apod/ap980213.html ] was launched (above) as the fourth stage of a Jupiter-C rocket (a modified US Army [ http://www.redstone.army.mil/history/firsts/firsts.html ] Redstone [ http://antwrp.gsfc.nasa.gov/apod/ap970406.html ] ballistic missile) and achieved orbit on January 31, 1958. Explorer I carried instrumentation [ http://history.msfc.nasa.gov/history/mm/lk_inst.html ] to measure internal and external temperatures, micrometeorite impacts, and an experiment designed by James A. Van Allen [ http://www.jamesvanallen.com/productionbiography.html ] to measure the density of electrons and ions in space. The measurements made by Van Allen's experiment led to an unexpected and startling discovery [ http://www-spof.gsfc.nasa.gov/Education/wexp13.html ] -- an earth-encircling belt of high energy electrons and ions trapped in the magnetosphere [ http://www-spof.gsfc.nasa.gov/Education/Intro.html ] now known as the Van Allen Belt [ http://es91-server1.msfc.nasa.gov/ssl/pad/sppb/MI/imagers.html ]. Explorer I ceased transmitting on February 28 of that year but remained in orbit until March of 1970.

GALEX Telescope
Title Nearby Newborns
Original Caption Released with Image Figure 1 This image shows six of the three-dozen "ultraviolet luminous galaxies" spotted in our corner of the universe by NASA's Galaxy Evolution Explorer. These massive galaxies greatly resemble newborn galaxies that were common in the early universe. The discovery came as a surprise, because astronomers had thought that the universe's "birth-rate" had declined, and that massive galaxies were no longer forming. The galaxies, located in the center of each panel, were discovered after the Galaxy Evolution Explorer scanned a large portion of the sky with its highly sensitive ultraviolet-light detectors. Because young stars pack most of their light into ultraviolet wavelengths, young galaxies appear to the Galaxy Evolution Explorer like diamonds in a field of stones. Astronomers mined for these rare "gems" before, but missed them because they weren't able to examine a large enough slice of the sky. The Galaxy Evolution Explorer surveyed thousands of nearby galaxies before finding three-dozen newborns. While still relatively close in astronomical terms, these galaxies are far enough away to appear small to the Galaxy Evolution Explorer. Clockwise beginning from the upper left, they are called: GALEX_J232539.24+004507.1, GALEX_J231812.98-004126.1, GALEX_J015028.39+130858.5, GALEX_J021348.52+125951.3, GALEX_J143417.15+020742.5, GALEX_J020354.02-092452.5.

Full Description This illustration shows the main characteristics of the Jupiter C launch vehicle and its payload, the Explorer I satellite. The Jupiter C, America's first successful space vehicle, launched the free world's first scientific satellite, Explorer 1, on January 31, 1958. The four-stage Jupiter C measured almost 69 feet in length. The first stage was a modified liquid fueled Redstone missile. This main stage was about 57 feet in length and 70 inches in diameter. Fifteen scaled down SERGENT solid propellant motors were used in the upper stages. A "tub" configuration mounted on top of the modified Redstone held the second and third stages. The second stage consisted of 11 rockets placed in a ring formation within the tub. Inserted into the ring of second stage rockets was a cluster of 3 rockets making up the third stage. A fourth stage single rocket and the satellite were mounted atop the third stage. This "tub", all upper stages, and the satellite were set spirning prior to launching. The complete upper assembly measured 12.5 feet in length. The Explorer I carried the radiation detection experiment designed by Dr. James Van Allen and discovered the Van Allen Radiation Belt.
Marjorie Townsend and SAS-1
Title Marjorie Townsend and SAS-1
Full Description Marjorie Townsend discusses the X-ray Explorer Satellite's performance with a colleague during preflight tests at NASA's Goddard Space Flight Center. Townsend, a Washington DC native, was the first woman to receive an engineering degree from The George Washington University. She joined NASA in 1959 and later advanced to become the project manager of the Small Astronomy Satellite (SAS) Program. The satellite shown in the picture, SAS-1, was the 42nd in NASA's Explorer series, a family of small, simple satellites sent to perform important scientific missions for minimal cost. The first Explorer satellite launched in 1958, months prior to the formation of NASA, initiating a program of exploration that has continued into the twenty-first century. SAS-1 continued the tradition of crucial science projects by carrying the first set of sensitive instruments designed to map X-ray sources both within and beyond our own galaxy, the Milky Way. Also known as Explorer 42 and the X-ray Explorer, it became the first American spacecraft launched by another country when an Italian space team launched it on December 12, 1970 from a mobile launch platform located in international waters off the coast of East Africa. It mapped the universe in X-ray wavelengths and discovered X-ray pulsars and evidence of black holes. The satellite was named Uhuru, which means freedom in Swahili, because it was launched from San Marco off the coast of Kenya on Kenya's Independence Day. In the 1970's the Italian Government made Townsend a Knight of the Italian Republic Order for her contributions to the United States-Italian space efforts. In 1990, Townsend joined BDM International Inc., as the director of Space Systems Engineering with the Space Science and Applications Division.
