Orbit of Sedna
Title Orbit of Sedna
Description This animation shows the location of the newly discovered planet-like object, dubbed "Sedna," in relation to the rest of the Solar System. Starting at the inner Solar System, which includes the orbits of Mercury, Venus, Earth, and Mars (all in yellow), the view pulls away through the asteroid belt and the orbits of the outer planets beyond (green). Pluto and the distant Kuiper Belt objects are seen next until finally Sedna comes into view. As the field widens the full orbit of Sedna can be seen along with its current location. Sedna is nearing its closest approach to the Sun, its 10,000-year orbit typically takes it to far greater distances. Moving past Sedna, what was previously thought to be the inner edge of the Oort cloud appears. The Oort cloud is a spherical distribution of cold, icy bodies lying at the limits of the Sun's gravitational pull. Sedna's presence suggests that this Oort cloud is much closer than scientists believed.

Description SOHO images show Saturn on the left moving toward the Sun
Full Description Saturn has a date to keep with Earth and the Sun. Since the Cassini spacecraft is orbiting Saturn, it's tagging along. Once a year Saturn and Earth find themselves almost directly opposite each other with the Sun in between, an event called conjunction. This year, conjunction will occur on Aug. 7. NASA's Solar and Heliospheric Observatory, known as SOHO (http://sohowww.nascom.nasa.gov/), keeps close watch on the Sun. SOHO images show Saturn on the left moving toward the Sun, which is shielded from view but represented by a white circle in the image center. When Saturn emerges from conjunction, it will appear in SOHO images heading toward the right and away from Sun. As Earth and Saturn play peekaboo with each other, radio communications with Cassini get very noisy, so most of Cassini's science operations are temporarily suspended. "We'll still be in constant communication," says David Doody, Cassini flight operations lead, "and we'll see the quality degrading as it nears the Sun. The last high-rate science data playback, at 14,220 bits per second, will occur Aug. 4, after which Cassini switches to low-rate telemetry downlink, at 1896 bps." During conjunction, the mission switches gears. "Finally, a break," says Doody. "We know the spacecraft is safe, especially since it won't be doing lots of commanded science activities, instead just staring at Earth with its high gain antenna. We'll be carrying out radio science studies of the solar corona, using carrier signals coming down from Cassini to study the sun's extended, super-hot atmosphere. Meanwhile, the spacecraft team's radio communications engineers will watch how many out of 100 test commands sent each day are received aboard the spacecraft with the noisy Sun in the way.""We'll also be using this low-activity period to conduct an operational readiness test, realistic training using contrived problems, for many of the new members of the flight team," adds Doody. Cassini will resume returning high-rate science data on Aug. 10, when it is well past the Sun. Note for sky watchers: The first time that Saturn will be visible again to the unaided eye from here on Earth will be about two weeks after conjunction. On the morning of Aug. 20, Saturn will rise in the east an hour before the sun does. Early birds in the United States will be able to spot swift Mercury one degree above Saturn. The next morning, they can spot Mercury one degree to the lower left of the planet. On Aug. 26 and 27 Saturn pairs with much brighter Venus. To see the latest image from SOHO click here.

Description August 2006: View of the Planets
Full Description Just before the eastern sky brightens with sunrise, three planets and the waning crescent moon join the starry twilight tapestry. Then, as the bright stars of Gemini and Orion fade with oncoming dawn, the planets rise and shine. About 45 minutes before sunrise on Aug. 20 to 22 the planets Venus, Mercury and Saturn dance on the ecliptic -- the plane of Earth's orbit and the imaginary line tracing it in the sky. The sun, moon and planets appear to move along this line. Venus, rising an hour and a half before sunrise, is the easiest to see in the morning sky. Two hundred forty-one million kilometers (150 million miles) distant, Venus is Earth-sized. Mercury, at a distance of 183 million kilometers (114 million miles), is the fastest and smallest of the inner planets and appears brighter than the more distant Saturn. Saturn, 1,517 million kilometers (943 million miles) distant, was at conjunction with the sun just two weeks ago and now rises nearly an hour before sunrise. On Aug. 26 and 27, Saturn pairs with much brighter Venus at dawn. What other planets can we see in late August? Mars sets 45 minutes after sunset by month's end but is lost from view in the twilight, while brilliant Jupiter remains prominent as the only planet visible for a few hours during the late August evenings.

Terrestrial Planet Interiors
title Terrestrial Planet Interiors
description *Mercury* Mercury has an average density of 5430 kilograms per cubic meter, which is second only to Earth among all the planets. It is estimated that the planet Mercury, like Earth, has a ferrous core with a size equivalent to two-thirds to three-fourths that of the planet's overall radius. The core is believed to be composed of an iron-nickel alloy covered by a mantle and surface crust. *Venus* It is believed that the composition of the planet Venus is similar to that of Earth. The planet crust extends to around 10-30 kilometers below the surface, under which the mantle reaches to a depth of some 3000 kilometers. The planet core comprises a liquid iron-nickel alloy. Average planet density is 5240 kilograms per cubic meter. *Earth* The Earth comprises three separate layers: a crust, a mantle, and a core (in descending order from the surface). The crust thickness averages 30 kilometers for land masses and 5 kilometers for seabeds. The mantle extends from just below the crust to some 2900 kilometers deep. The core below the mantle begins at a depth of around 5100 kilometers, and comprises an outer core (liquid iron-nickel alloy) and inner core (solid iron-nickel alloy). The crust is composed mainly of granite in the case of land masses and basalt in the case of seabeds. The mantle is composed primarily of peridotite and high-pressure minerals. Average planet density is 5520 kilograms per cubic meter. *Mars* Mars is roughly one-half the diameter of Earth. Due to its small size, it is believed that the martian center has cooled. Geological structure is mainly rock and metal. The mantle below the crust comprises iron-oxide-rich silicate. The core is made up of an iron-nickel alloy and iron sulfide. Average planet density is 3930 kilograms per cubic meter. *Pluto* The structure of Pluto is not very well understood at present. Nevertheless, spectroscopic observation from Earth in the 1970s has revealed that the planet surface is covered with methane ice. Surface temperature is -230?C (-382?F), and the frozen methane exhibits a bright coloration. However, with the exception of the polar caps, the frozen methane surface is seen to change to a dark red when eclipsed by its moon Charon. Average planet density is 2060 kilograms per cubic meter. The low average density requires that the planet must be a mix of ice and rock. *Image Credit*: Lunar and Planetary Institute
Planet Temperatures
title Planet Temperatures
description In general, the surface temperature of the planets decreases with increasing distance from the Sun. Venus is an exception because its dense atmosphere acts as a greenhouse and heats the surface to above the melting point of lead (3280C). Mercury rotates slowly and has a thin atmosphere, and consequently, the nightside temperature can be more than 5000C lower than the dayside temperature shown on the diagram. Temperatures for the gas giants (Jupiter, Saturn, Uranus, and Neptune) are shown at a level in the atmosphere equal in pressure to sea level on Earth. Temperatures are in both Fahrenheit and Celsius, and the planets are not shown to scale. *Image Credit*: Lunar and Planetary Institute
Brahms Crater
title Brahms Crater
date 03.30.1974
description Thirty years ago, NASA's Mariner 10 spacecraft made the first of three passes by Mercury, sending back intriguing images of the planet's battered terrain. NASA will launch the world's second probe to Mercury - named MESSENGER - this summer.This image of the crater was taken on the first flyby. Note the central peak. North is up. (Mariner 10, Atlas of Mercury, Fig. 3-2) This crater (98 km diameter) illustrates the narrow hummocky rim facies, radial ridges, and surrounding extensive field of secondary craters. The well-developed interior terraces and central peaks are typical for mercurian craters in this size range. Note that the smaller craters in the foreground (25-km diameter) also are terraced. This image(FDS 80)was taken during the spacecraft's first encounter with Mercury. The Mariner 10 mission, managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, explored Venus in February 1974 on the way to three encounters with Mercury-in March and September 1974 and in March 1975. The spacecraft took more than 7,000 photos of Mercury, Venus, the Earth and the Moon. *Image Credi*: NASA
Terrestrial Planet Sizes
title Terrestrial Planet Sizes
description The terrestrial planets are the four innermost planets in the solar system, Mercury, Venus, Earth, and Mars. They are called terrestrial because they have a compact, rocky surface like the Earth's. The planets Venus, Earth, and Mars have significant atmospheres, while Mercury has almost none. This diagram shows the approximate relative sizes of the terrestrial planets. Distances are not to scale. *Image Credit*: Lunar and Planetary Institute
Solar System Family Portrait
title Solar System Family Portrait
description These six narrow-angle color images were made from the first ever 'portrait' of the solar system taken by Voyager 1, which was more than 4 billion miles from Earth and about 32 degrees above the ecliptic. The spacecraft acquired a total of 60 frames for a mosaic of the solar system which shows six of the planets. Mercury is too close to the sun to be seen. Mars was not detectable by the Voyager cameras due to scattered sunlight in the optics, and Pluto was not included in the mosaic because of its small size and distance from the sun. These blown-up images, left to right and top to bottom are Venus, Earth, Jupiter, and Saturn, Uranus, Neptune. The background features in the images are artifacts resulting from the magnification. The images were taken through three color filters -- violet, blue and green -- and recombined to produce the color images. Jupiter and Saturn were resolved by the camera but Uranus and Neptune appear larger than they really are because of image smear due to spacecraft motion during the long (15 second) exposure times. Earth appears to be in a band of light because it coincidentally lies right in the center of the scattered light rays resulting from taking the image so close to the sun. Earth was a crescent only 0.12 pixels in size. Venus was 0.11 pixel in diameter. The planetary images were taken with the narrow-angle camera (1500 mm focal length). *Image Note*: This 'Portrait' contains 18 frames taken through the Narrow Angle camera using the Violet, Blue, and Green Filters. The label information describes only 3 of these frames. *Image Credit*: NASA
Jupiter Flyby

Outward from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. Jupiter's diameter is about 11 times that of the Earth's and the Sun's diameter is about 10 times Jupiter's. Pluto's diameter is slightly less than one-fifth of Earth's. The planets are not shown at the appropriate distance from the Sun. *Image Credit*: Lunar and Planetary Laboratory
Young Craters
title Young Craters
description Young craters (the largest of which is about 100 kilometers in diameter) superposed on smooth plains. Larger young craters have central peaks, flat floors, terraced walls, radial ejecta deposits, and surrounding fields of secondary craters. Smooth plains have well-developed ridges extending northwest and northeast. This image (FDS 167) was acquired during the Mariner 10's first encounter with Mercury, is located approximately 60 degrees N, 175 degrees W. The Mariner 10 mission was managed by the Jet Propulsion Laboratory for NASA's Office of Space Science.

Mercury's South Pole
title Mercury's South Pole
date 09.21.1974
description Mercury's south pole was photographed by one of Mariner 10's TV cameras as the spacecraft made its second close flyby of the planet September 21. The pole is located inside the large crater (180 kilometers, 110 miles) on Mercury's limb (lower center). The crater floor is shadowed and its far rim, illuminated by the sun, appears to de disconnected from the edge of the planet. Just above and to the right of the South Pole is a double ring basin about 100 kilometers (125 miles) in diameter. A bright ray system, splashed out of a 50 kilometer (30 mile) crater is seen at upper right. The stripe across the top is an artifact introduced during computer processing. The picture (FDS 166902) was taken from a distance of 85,800 kilometers (53,200 miles) less than two hours after Mariner 10 reached its closest point to the planet. The Mariner 10 mission, managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, explored Venus in February 1974 on the way to three encounters with Mercury-in March and September 1974 and in March 1975. The spacecraft took more than 7,000 photos of Mercury, Venus, the Earth and the Moon. *Image Credit*: NASA/JPL/Northwestern University

Date of Image 1961-01-01
Full Description Progress in the Saturn program, depicted below, was described by Dr. Wernher von Braun, Marshall Space Flight Center (MSFC) Director, in an appearance before the Senate Committee of Aeronautical and Space Sciences. "The flight configuration of the giant three-stage Saturn C-1 rocket (later called Saturn I Block I) is seen in the Fabrication and Assembly Engineering Division at MSFC. Dwarfed by the 180-foot C-1 are a Juno II rocket (left rear) and a Mercury-Redstone rocket (front foreground). The C-1 (first version of the Saturn rocket) is composed of an S-1 first stage or booster (rear), powered by eight H-1 engines having a thrust of 1,500,000 pounds, followed by a dummy S-IV second stage and a dummy S-V third stage. The "live" S-IV for later flights, under development by Douglas Aircraft Co., will be powered by four Pratt Whitney LR-119 engines having 17,500,000 pounds thrust each. The live S-V, under development by Convair Division of General Dynamics Corp., will use two LR-119 engines. With all three stages live, the C-1 will be capable of placing 19,000 pounds into a 300-mile Earth orbit, sending 5,000 pounds to escape velocity, or lofting 2,500 pounds to Mars or Venus. The second version Saturn C-2 (later called Saturn 1 Block II) would double these capabilities. Early C-1 flights will employ a live S-1 with dummy upper stages. The first such flight is scheduled late this year.

Title Mercury at First Encounter Closest Approach
Description Taken only minutes after Mariner 10 made its closest approach to the planet Mercury on March 29, this is one of the highest resolution pictures obtained during the mission. Craters as small as 150 meters (500 feet) across can be seen. The picture, taken from a distance of about 5900 kilometers (3700 miles), measures 50 by 40 kilometers 931 by 25 miles). The relativity level surface contrasts with the abundant relief seen in some close-up views on the opposite side of the planet. The long, narrow area of hills and scarps to the left resembles ridges in the mare of Earth's moon. Abundant craters in various stages of degradation dot the surface. The Mariner 10 mission, managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, explored Venus in February 1974 on the way to three encounters with Mercury-in March and September 1974 and in March 1975. The spacecraft took more than 7,000 photos of Mercury, Venus, the Earth and the Moon. NOTE: This image was scanned from physical media.

Field of Bright Rays
Title Field of Bright Rays
Description A field of bright rays--created by ejecta from a crater--radiating to the north (top) from off camera (lower right) is seen in this view of Mercury taken September 21 by Mariner 10. Source of the rays is a large new crater to the south, near Mercury's South Pole. Mariner 10 was about 48,000 kilometers (30,000 miles) from Mercury when the picture (FDS 166749) was taken at 2:01 p.m. PDT, just three minutes after the spacecraft was closest to the planet. Largest crater in this picture is 100 kilometers (62 miles) in diameter. The Mariner 10 mission, managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, explored Venus in February 1974 on the way to three encounters with Mercury-in March and September 1974 and in March 1975. The spacecraft took more than 7,000 photos of Mercury, Venus, the Earth and the Moon. Image Credit: NASA/JPL/Northwestern University

Title Heavily Cratered Terrain at South Pole
Description Mariner 10 obtained this picture (FDS 166619) of an area 460 by 640 kilometers (285 by 400 miles) in the Southern hemisphere of Mercury during its second encounter with the planet on September 21, 1974. Taken from a distance of 78,000 kilometers (48,000 miles), the photo reveals a heavily cratered terrain with a prominent scrap extending several hundred kilometers across the upper left. A 40-kilometer-diameter (25 miles) crater, nested in a larger crater, 120 kilometers (75 miles), is at top center. A basin about 240 kilometers (15 miles) in diameter is barely discernible at lower right. Crater chains produced by material ejected from a larger crater located outside the field of view appear at lower left. The smallest details measure about 1.7 kilometers (one mile). The Mariner 10 mission, managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, explored Venus in February 1974 on the way to three encounters with Mercury-in March and September 1974 and in March 1975. The spacecraft took more than 7,000 photos of Mercury, Venus, the Earth and the Moon. Image Credit: NASA/JPL/Northwestern University

Title Large Circular Basin - 1300-km diameter
Description Close-up view of one-half of a 1300-km diameter circular basin the largest observed on Mercury. The other half is hidden beyond the terminator to the left. Hills and valleys extend in a radial fashion outward from the main ring. Interior of the large basin is completely flooded by plains materials, adjacent lowlands are also partially flooded and superimposed on the plains are bowl shaped craters. Wrinkle ridges are abundant on the plains materials. The area shown is 1008 miles (1600 km) from the top to the bottom of the picture. Sun's illumination is from the right. Blurred linear lines extending across the picture near bottom are missing data lines that have been filled in by the computer. Mariner 10 encountered Mercury on Friday, March 29th, 1974, passing the planet on the darkside 431 miles (690-km) from the surface. The Mariner 10 mission, managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, explored Venus in February 1974 on the way to three encounters with Mercury-in March and September 1974 and in March 1975. The spacecraft took more than 7,000 photos of Mercury, Venus, the Earth and the Moon. NOTE: This image was scanned from physical media.

First HiRISE image of Mars
title First HiRISE image of Mars
Description . NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter for NASA's Science Mission Directorate, Washington. Lockheed Martin Space Systems is the prime contractor for the project and built the spacecraft. The HiRISE camera was built by Ball Aerospace and Technology Corporation and is operated by the University of Arizona. Credit: NASA/JPL/University of Arizona, The first image of Mars by the High Resolution Imaging Science Experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter shows a story of geologic change in the eastern Bosporos Planum region. Old stream valleys cut into the flanks of a gently sloping mountain range in the center of the image. Layers of smooth-textured deposits have mantled the stream valleys and many impact craters. Wind and sublimation of water or carbon dioxide ice have partially eroded patches of the smooth-textured deposits, leaving behind areas of layered and hummocky terrain. A prominent ridge that extends from the top to the bottom of the image dominates the scene. This ridge formed above a thrust fault, a type of fault that occurs when the surface of a planet is compressed. On planetary surfaces, such fault-related ridges are termed "wrinkle ridges." They are commonly observed on Mars, as well as on Earth's moon and on Venus and Mercury. The wrinkle ridge imaged here is named Ogygis Rupes. This wrinkle ridge has deformed several valleys and impact craters. Throughout the scene, geologically young sand dunes are present within stream valleys and some impact craters. The area is also sprinkled with many small young impact craters, which are distinguished by sharp crater rims and bright or dark halos of ejected material. This image demonstrates how a single HiRISE image can capture a multitude of geologic processes. Image AEB_000001_0000_Red was taken by HiRISE on March 24, 2006. The image is centered at 33.65 degrees south latitude, 305.07 degrees east longitude. It is oriented such that north is 7 degrees to the left of up. The range to the target was 2,493 kilometers (1,549 miles). At this distance the image scale is 2.49 meters (8.17 feet) per pixel, so objects as small as 7.5 meters (24.6 feet) are resolved. In total this image is 49.92 kilometers (31.02 miles) or 20,081 pixels wide and 23.66 kilometers (14.70 miles) or 9,523 pixels long. The image was taken at a local Mars time of 07:33 and the scene is illuminated from the upper right with a solar incidence angle of 78 degrees, thus the sun was 12 degrees above the horizon. At an Ls of 29 degrees (with Ls an indicator of Mars' position in its orbit around the sun), the season on Mars is southern autumn.

Title Mercury: Photomosaic of the Kuiper Quadrangle H-6
Original Caption Released with Image The Kuiper Quadrangle was named in memory of Dr. Gerard Kuiper, a Mariner 10 Venus/Mercury imaging team member and well-known astronomer, who passed away several months before the spacecraft's arrival at Mercury. The Kuiper crater, located left of center, is the brightest and perhaps youngest crater is 60 km in diameter located at -11 degrees latitude and 31 degrees longitude. The Image Processing Lab at NASA's Jet Propulsion Laboratory produced this photomosaic using computer software and techniques developed for use in processing planetary data. The images used to construct the Kuiper Quadrangle were taken during Mariner's first and third flybys of Mercury. The Mariner 10 spacecraft was launched in 1974. The spacecraft took images of Venus in February 1974 on the way to three encounters with Mercury in March and September 1974 and March 1975.

Title Mercury: Photomosaic of the Shakespeare Quadrangle of Mercury (Southern Half) H-3
Original Caption Released with Image This computer generated photomosaic from Mariner 10 is of the southern half of Mercury's Shakespeare Quadrangle, named for the ancient Shakespeare crater located on the upper edge to the left of center. This portion of the quadrangle covers the geographic region from 20 to 45 degrees north latitude and from 90 to 180 degrees longitude. The photomosaic was produced using computer techniques and software developed in the Image Processing Laboratory of NASA's Jet Propulsion Laboratory. The pictures have been high-pass filtered and contrast enhanced to accentuate surface detail, and geometrically transformed into a Lambert conformal projection. Well defined bright streaks or ray systems radiating away from craters constitute another distinctive feature of the Mercurian surface, remarkably similar to the Moon. The rays cut across and are superimposed on all other surface features, indicating that the source craters are the youngest topographic features on the surface of Mercury. The above material was taken from the following publication... Davies, M. E., S. E. Dwornik, D. E. Gault, and R. G. Strom, Atlas of Mercury,NASA SP-423 (1978). The Mariner 10 mission was managed by the Jet Propulsion Laboratory for NASA's Office of Space Science.

Title Mercury: Photomosaic of the Shakespeare Quadrangle (Northern Half) H-3
Original Caption Released with Image This computer generated photomosaic from Mariner 10 is of the northern half of Mercury's Shakespeare Quadrangle, named for the ancient Shakespeare crater located on the lower edge to the left of center. This portion of the quadrangle covers the geographic region from 45 to 70 degrees north latitude and from 90 to 180 degrees longitude. The photomosaic was produced using computer techniques and software developed in the Image Processing Laboratory of NASA's Jet Propulsion Laboratory. The pictures have been high-pass filtered and contrast enhanced to accentuate surface detail, and geometrically transformed into a Lambert conformal projection. The illuminated surface observed by Mariner 10 as it first approached Mercury is dominated by craters and basins. In marked contrast to this view, the surface photographed after the flyby exhibited features totally different, including large basins and extensive relatively smooth areas with few craters. The most striking feature in this region of the planet is a huge circular basin, 1300 kilometers in diameter, that was undoubtedly produced from a tremendous impact comparable to the event that formed the Imbrium basin on the Moon. This prominent Mercurian structure in the Shakespeare and Tolstoj quadrangles (lower left corner of this image), named Caloris Planitia, is filled with material forming a smooth surface or plain that appears similar in many respects to the lunar maria. The above material was taken from the following publication... Davies, M. E., S. E. Dwornik, D. E. Gault, and R. G. Strom, Atlas of Mercury, NASA SP-423 (1978). The Mariner 10 mission was managed by the Jet Propulsion Laboratory for NASA's Office of Space Science.

Title Mercury: Photomosaic of the Tolstoj Quadrangle H-8
Original Caption Released with Image This computer generated photomosaic from Mariner 10 is of Mercury's Tolstoj Quadrangle, named for the ancient Tolstoj crater located in the lower center of the image. This quadrangle covers the geographic region from 25 degrees south to 25 degrees north latitude and from 144 to 216 degrees longitude. The photomosaic was produced using computer techniques and software developed in the Image Processing Laboratory of NASA's Jet Propulsion Laboratory. The pictures have been high-pass filtered and contrast enhanced to accentuate surface detail, and geometrically transformed into a Mercator conformal projection. The extensive areas of smooth surfaces or plains depicted in this mosaic have been classified into three types. The most widespread type forms a level to gently rolling ground between and around large craters and basins, and characterized by an extremely high density of superimposed small craters. A second type, "hummocky" plains, occurs within a broad ring that is 600 to 800 kilometers wide and circumscribes the Caloris Planitia (in the upper left corner of the image). These plains consist of low, closely spaced to scattered hills. "Smooth" plains are the third type and form relatively level tracts with a very low population of craters, both within and external to the basins. The above material was taken from the following publication... Davies, M. E., S. E. Dwornik, D. E. Gault, and R. G. Strom, Atlas of Mercury, NASA SP-423 (1978).

Title Mercury: Photomosaic of the Michelangelo Quadrangle H-12
Original Caption Released with Image The Michelangelo Quadrangle, which lies in Mercury's southern polar region, was named in memory of the famous Italian artist. The Mercurian surface is heavily marred by numerous impact craters. Ejecta deposits, seen as bright lines or rays, radiate outward from the point of impact, along the planet's surface indicating the source craters are young topographical features. The rays found on Mercury are similar to ones found on the surface of Earth's moon. Several large lobate scarps, steep and long escarpments which usually show a largely lobate outline on a scale of a few to tens of kilometers, are clearly visible in the lower left side of the image slicing through a variety of terrains including several large impact craters. The Image Processing Lab at NASA's Jet Propulsion Laboratory produced this photomosaic using computer software and techniques developed for use in processing planetary data. The images used to construct the Michelangelo Quadrangle were taken during Mariner 10's second flyby of Mercury. The Mariner 10 spacecraft was launched in 1974. The spacecraft took images of Venus in February 1974 on the way to three encounters with Mercury in March and September 1974 and March 1975.

Title Solar System Portrait - Views of 6 Planets
Original Caption Released with Image These six narrow-angle color images were made from the first ever 'portrait' of the solar system taken by Voyager 1, which was more than 4 billion miles from Earth and about 32 degrees above the ecliptic. The spacecraft acquired a total of 60 frames for a mosaic of the solar system which shows six of the planets. Mercury is too close to the sun to be seen. Mars was not detectable by the Voyager cameras due to scattered sunlight in the optics, and Pluto was not included in the mosaic because of its small size and distance from the sun. These blown-up images, left to right and top to bottom are Venus, Earth, Jupiter, and Saturn, Uranus, Neptune. The background features in the images are artifacts resulting from the magnification. The images were taken through three color filters -- violet, blue and green -- and recombined to produce the color images. Jupiter and Saturn were resolved by the camera but Uranus and Neptune appear larger than they really are because of image smear due to spacecraft motion during the long (15 second) exposure times. Earth appears to be in a band of light because it coincidentally lies right in the center of the scattered light rays resulting from taking the image so close to the sun. Earth was a crescent only 0.12 pixels in size. Venus was 0.11 pixel in diameter. The planetary images were taken with the narrow-angle camera (1500 mm focal length).
