Photo by Voyager 1 (JPL) The spacecraft took this photo of the planet Jupiter on Jan 24, while still more than 25 million miles (40 million kilometers) away. As the spacecraft draws closer to the planet (about 1 million kilometers a day) more details are emergng in the turbulent clouds. The Great Red Spot shows prominently below center, surrounded by what scientists call a remarkably complex region of the giant planet's atmosphere. An elongated yellow cloud within the Great Red Spot is swirling around the spot's interior boundary in a counterclockwise direction with a period of a little less than six days, confirming the whirlpool-like circulation that astronomers have suspected from ground-based photographs. Ganymede, Jupiter's largest satellite, can be seen to the lower left of the planet. Ganymede is a planet-sized body larger than Mercury. This color photo was assembled at Jet Propulsion Laboratory's Image Processing Lab from there black and white images taken through filters. The Voyagers are managed for NASA's Office of Space Science by Jet Propulsion Laboratory.  (ref: P-20945C  Mission Image 1-9) ARC-1979-AC79-0143-3

Range :  1 illion km. ( 600,000 mi. ) Resolution :  140 km. ( 90 mi. ) P-29539C This Voyager 2 image of Uranus was captured as the spacecraft was leaving Uranus behind on its cruise to Neptune. The image is a color composite of three photographs taken through blue, grren, and orange filters. Thin thin crecent seen here is at an angle of 153 degrees between the the spacecraft, the planet, and the sun. Even at this extreme angle, uranus retains the pale blue-green color seen  by the ground based astronomers and recorded by Voyager 2 during its historic encounter, this color results from the presence of methane in Uranus' atmosphere. The gas absorbs red wavelengths of light, leaving the predominant hue seen here. The tendency for the cresent to become white at the extreme edge is cased by the presence of a high-altitude haze. Voyager 2, having encountered Jupiter in 1979, Saturn in 1981, and Uranus in 1986, will proceed on its jouney to Neptune. Closest approach is scheduled for August 24, 1989. ARC-1986-AC86-7042

Artist: Rick Guidice SIRTF Artwork update - cutaway  Space Infrared Telescope Facility's  will orbit at 900 kilometers aboard a platform-type spacecraft, providing power, pointing, and communications to Earth. The telescope and its infrared instruments, will reside within a cylindrical cryogen tank. The hollow walls of the tank will contain the superfluid helium that cools the telescope to its operating temperature, a few degrees above absolute zero.   SIRTF will carry three versatile instruments to analyze the radiation it collects, the Multiband Imaging Photometer, the Infrared Array Camera, and the Infrared Spectrograph. SIRTF long lifetime - 5 years or more - will permit astronomers of all disciplines to use the facililty to carry out a wide variety of astrophysical programs. It will provide ongoing coverage of variable objects, such as quasars, as well as the capability to study rare and transient events such as comets and supernovae. SIRTF's long lifetime will also allow it to distinguish nearby objects by detecting their gradual motions relative to the more distant background stars. ARC-1988-AC88-0595

P-34578 BW One of two new ring arcs, or partial rings, discovered by Voyager 2, is faintly visible just outside the orbit of the Neptunian moon 1989N4.The 155-second exposure taken by the spacecraft's narrow-angle camera shows the glare of an overexposed Neptune to the right of the moon and ring arc. The two bright streaks below the moon and ring arc are stars. The ring arc is approximately 50,000 kilometers (30,000 miles) long. The second ring arc, not apparent here, is about 10,000 kilometers (6,000 miles) long and is assoiciated with moon 1989N3. The ring arc, along with 1989N4, orbits about 62,000 kilometers (38,000 miles) from the planet's cloud tops. Astronomers long suspected the existence of such an irregular ring system around Neptune. Data from repeated ground-based observations hinted at the existence of irregular strands of partial rings orbiting Neptune. Voyager's photographs of the ring arcs are the first photographic evidence that such a ring system exists. Voyager scientists said the ring arcs may be comprised of debris associated with the nearby moons, or may be the remnants of moons that have been torn apart or ground down through collisions. Close-up studies of the ring arcs by Voyager 2 will help determine their composition. ARC-1989-A89-7042

This image is the first full picture showing both asteroid 243 Ida and its newly discovered moon to be transmitted to Earth from NASA's Galileo spacecraft--the first conclusive evidence that natural satellites of asteroids exist.  Ida is the large object to the left, about 56 kilometers (35 miles long).  Ida's natural satellite is the small object to the right.  This portrait was taken by Galileo's charge-coupled device (CCD) camera on August 28, 1993, about 14 minutes before the spacecraft's closest approach to the asteriod, from a range of 10,870 kilometers (6,755 miles).  Ida is a heavily cratered, irregularly shaped asteroid in the main asteroid belt between Mars and Jupiter-- the 243rd asteroid to be discovered since the first one was found at the beginning of the 19th century.  It is a member of a group of asteroids called the Koronis family.  The small satellite, which is about 1.5 kilometers (1 mile) across in this view, has yet to be given a name by astronomers.  It has been provisionally designated '1993 (243) 1' by the International Astronomical Union.  (The numbers denote the year the picture was taken, the asteroid number and the fact that it is the first moon of Ida to be found.)  ALthough the satellite appears to be 'next' to Ida it is actually slightly in the foreground, closer to the spacecraft than Ida.  Combining this image with data from Galileo's near-infrared mapping spectrometer, the science team estimates that the object is about 100 kilometers (60 miles) away from the center of Ida.  This image is one of a six-frame series taken through different color filters, this one in green.  The spatial resolution in this image is about 100 meters (330 feet) per pixel.  The Galileo spacecraft flew past Ida en route to its final destination, Jupiter, where it will go into orbit in December 1995.  The Jet Propulsion Laboratory manages the galileo Project for NASA's Office of Space Science. (JPL ref. No. P-43731) ARC-1994-A91-2018

KENNEDY SPACE CENTER, FLA. -- In the Multi-Payload Processing Facility, NASA's Galaxy Evolution Explorer spacecraft is moved to a rotation stand in preparation for mating with the Pegasus XL launch vehicle. The GALEX, set to launch April 2 from Cape Canaveral Air Force Station, will carry into space an orbiting telescope that will observe a million galaxies across 10 billion years of cosmic history to help astronomers determine when the stars and elements we see today had their origins. From its orbit high above Earth, the spacecraft will sweep the skies for 28 months using state-of-the-art ultraviolet detectors.  Looking in the ultraviolet will single out galaxies dominated by young, hot, short-lived stars that give off a great deal of energy at that wavelength.  These galaxies are actively creating stars, and therefore provide a window into the history and causes of star formation in galaxies. KSC-03pd0621

KENNEDY SPACE CENTER, FLA. -  In the early morning light, the mated Pegasus XL and Galaxy Evolution Explorer (GALEX) satellite are seen near the Orbital Sciences L-1011 aircraft at Cape Canaveral Air Force Station.  The GALEX, to be launched April 28 from the L-1011, will carry into space an orbiting telescope that will observe a million galaxies across 10 billion years of cosmic history to help astronomers determine when the stars and elements we see today had their origins. The spacecraft will sweep the skies for 28 months using state-of-the-art ultraviolet detectors to single out galaxies dominated by young, hot, short-lived stars that give off a great deal of energy at that wavelength.  These galaxies are actively creating stars, and therefore provide a window into the history and causes of star formation in galaxies. KSC-03pd1240

KENNEDY SPACE CENTER, FLA. - Orbital Sciences’ L-1011 aircraft takes off from Cape Canaveral Air Force Station carrying the Pegasus XL rocket/Galaxy Evolution Explorer (GALEX) under its belly.  Release of the Pegasus was scheduled for about 8 a.m. over the Atlantic Ocean at an altitude of 39,000 feet at a location approximately 100 nautical miles offshore east-northeast of Cape Canaveral. Spacecraft separation from the Pegasus occurs 11 minutes later. At that time the satellite will be in a circular orbit of 431 statute miles (690 km) at a 29-degree inclination.
