Planet Mercury
Title Planet Mercury
Full Description Mariner 10's first image of Mercury acquired on March 24, 1974. During its flight, Mariner 10's trajectory brought it behind the lighted hemisphere of Mercury, where this image was taken, in order to acquire important measurements with other instruments. This picture was acquired from a distance of 3,340,000 miles (5,380,000 km) from the surface of Mercury. The diameter of Mercury (3,031 miles, 4,878 km) is about 1/3 that of Earth. Images of Mercury were acquired in two steps, an inbound leg (images acquired before passing into Mercury's shadow) and an outbound leg (after exiting from Mercury's shadow). More than 2300 useful images of Mercury were taken, both moderate resolution (3-20 km/pixel) color and high resolution (better than 1 km/pixel) black and white coverage.

Mercury-Atlas Test Launch
Title Mercury-Atlas Test Launch
Full Description A NASA Project Mercury spacecraft was test launched at 11:15 AM EST on April 25, 1961 from Cape Canaveral, Florida, in a test designed to qualify the Mercury Spacecraft and all systems, which must function during orbit and reentry from orbit. The Mercury-Atlas vehicle was destroyed by Range Safety Officer about 40 seconds after liftoff. The spacecraft was recovered and appeared to be in good condition. Atlas was designed to launch payloads into low Earth orbit, geosynchronous transfer orbit or geosynchronous orbit. NASA first launched Atlas as a space launch vehicle in 1958. Project SCORE, the first communications satellite that transmitted President Eisenhower's pre-recorded Christmas speech around the world, was launched on an Atlas. For all three robotic lunar exploration programs, Atlas was used. Atlas/ Centaur vehicles launched both Mariner and Pioneer planetary probes. The current operational Atlas II family has a 100% mission success rating. For more information about Atlas, please see Chapter 2 in Roger Launius and Dennis Jenkins' book To Reach the High Frontier published by The University Press of Kentucky in 2002.

Title First Mercury-Atlas Attempted Launch
Full Description An Atlas vehicle is shown as it is raised into its launch gantry. This Atlas attempted to launch a Mercury spacecraft (without any astronauts aboard) into orbital flight. The launch vehicle developed 360,000 pounds of thrust and burned RP-1, a kerosene-like fuel, and liquid oxygen. It was about 60 feet in length and 10 feet in diameter at the tank section. This was the first attempt by NASA to put a Mercury spacecraft into Earth orbit. Unfortunately, this Atlas exploded at launch. Atlas was designed to launch payloads into low Earth orbit, geosynchronous transfer orbit or geosynchronous orbit. NASA first launched Atlas as a space launch vehicle in 1958.

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

Title Mercury: Closest Planet to the Sun
Explanation This picture was compiled from images taken by the NASA spacecraft Mariner 10 which flew by the planet three times in 1974. Mercury [ http://seds.lpl.arizona.edu/nineplanets/nineplanets/mercury.html ] is the closest planet to the Sun [ http://antwrp.gsfc.nasa.gov/apod/ap950813.html ], the second hottest planet (Venus gets hotter), and the second smallest planet (Pluto is smaller). Mercury [ http://www.c3.lanl.gov/~cjhamil/SolarSystem/mercury.html ] rotates so slowly that one day there - "day" meaning the normal time it takes from sunset to sunset - lasts 176 days on Earth [ http://antwrp.gsfc.nasa.gov/apod/ap950622.html ]. It is difficult to see Mercury [ http://nssdc.gsfc.nasa.gov/photo_gallery/photogallery-mercury.html ] not because it is dim but because it always appears near the Sun, and is therefore only visible for a short time just after sunset or just before sunrise. Mercury is made of rocky material like Earth. No one knows why Mercury has the magnetic field that it does. Tomorrow's picture: Venus: Earth's Sister Planet

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.

date 03.28.1974
description Mercury: The desert closest to the sun. Computer Photomosaic of the Caloris Basin The largest basin on Mercury (1300 km or 800 miles across) was named Caloris (Greek for "hot") because it is one of the two areas on the planet that face the Sun at perihelion. 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 Mariner 10 spacecraft imaged the region during its initial flyby of the planet. 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'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
Southwest Mercury
Title Southwest Mercury
Explanation The planet Mercury resembles a moon. Mercury [ http://seds.lpl.arizona.edu/nineplanets/nineplanets/mercury.html ]'s old surface is heavily cratered [ http://antwrp.gsfc.nasa.gov/apod/ap950924.html ] like many moons. Mercury [ http://bang.lanl.gov/solarsys/mercury.htm ] is larger than most moons but smaller than Jupiter [ http://antwrp.gsfc.nasa.gov/apod/ap951013.html ]'s moon Ganymede [ http://antwrp.gsfc.nasa.gov/apod/ap950904.html ] and Saturn [ http://antwrp.gsfc.nasa.gov/apod/ap960717.html ]'s moon Titan [ http://antwrp.gsfc.nasa.gov/apod/ap950923.html ]. Mercury is much denser and more massive than any moon, though, because it is made mostly of iron. In fact, the Earth [ http://antwrp.gsfc.nasa.gov/apod/ap960819.html ] is the only planet more dense. A visitor to Mercury's surface [ http://antwrp.gsfc.nasa.gov/apod/ap960121.html ] would see some strange sights. Because Mercury [ http://www.oulu.fi/~spaceweb/textbook/mercury.html ]rotates exactly three times every two orbits around the Sun [ http://antwrp.gsfc.nasa.gov/apod/ap951004.html ], and because Mercury [ http://nssdc.gsfc.nasa.gov/photo_gallery/PhotoGallery-Mercury.html ]'s orbit is so elliptical, a visitor to Mercury [ http://antwrp.gsfc.nasa.gov/apod/ap960912.html ] might see the Sun [ http://antwrp.gsfc.nasa.gov/htmltest/gifcity/interv.html ] rise, stop in the sky, go back toward the rising horizon [ http://antwrp.gsfc.nasa.gov/apod/ap951114.html ], stop again, and then set quickly over the other horizon. From Earth [ http://antwrp.gsfc.nasa.gov/apod/ap951118.html ], Mercury's proximity to the Sun [ http://antwrp.gsfc.nasa.gov/apod/ap960727.html ] cause it to be visible only for a short time [ http://www.maths.qmw.ac.uk/~lms/research/skyeye.html#planet ] just after sunset or just before sunrise.

Title Kuiper Crater
Original Caption Released with Image The Mariner 10 Television-Science Team has proposed the name "Kuiper" for this very conspicuous bright Mercury crater (top center) on the rim of a larger older crater. Prof. Gerard P. Kuiper, a pioneer in planetary astronomy and a member of the Mariner 10 TV team, died December 23, 1973, while the spacecraft was enroute to Venus and Mercury. Mariner took this picture (FDS 27304) from 88,450 kilometers (55,000 miles) some 2 1/2 hours before it passed Mercury on March 29. The bright-floored crater, 41 kilometers (25 miles) in diameter, is the center of a very large bright are which could be seen in pictures sent from Mariner 10 while Mercury was more than two million miles distant. The larger crater is 80 kilometers (50 miles) across. 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.

Title Hero Rupes Scarp
Original Caption Released with Image After passing Mercury the first time and making a trip around the Sun, Mariner 10 again flew by Mercury on September 21 at 1:59 PMPDT. This encounter brought the spacecraft in front of Mercury in the southern hemisphere. Hero Rupes, the large scarp visible running across the bottom of the image, is thought to thought to have been formed by global tectonic forces, possibly due to shrinkage of the planet as it cooled. Mariner 10 was looking obliquely across Mercury's southern hemisphere when it acquired this dramatic shot near the beginning of its southern hemisphere pass (FDS166618). 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.

3D Mercury Transit
Title 3D Mercury Transit
Explanation Mercury is now [ http://www.astronomy.com/ASY/CS/forums/314872/ ShowPost.aspx ] visible shortly before dawn, the brightest "star" just above the eastern horizon. But almost two weeks ago Mercury [ http://antwrp.gsfc.nasa.gov/apod/ap061114.html ] actually crossed the face of the Sun for the second time in the 21st century. Viewed with red/blue glasses [ http://photojournal.jpl.nasa.gov/Help/VendorList.html ], this stereo anaglyph combines space-based images of the Sun and innermost planet in a just-for-fun 3D [ http://www.sungazer.net/3dtransit.html ] presentation of the Mercury transit [ http://www.transitofvenus.org/mercury.htm ]. The solar disk image is from Hinode [ http://solarb.msfc.nasa.gov/index.html ]. (sounds like "hee-no-day", means sunrise). A sun-staring observatory, Hinode was launched from Uchinoura Space Center and viewed the transit [ http://solar-b.nao.ac.jp/news_e/20061109_e.shtml ] from Earth orbit. Superimposed on Mercury's dark silhouette is a detailed image [ http://antwrp.gsfc.nasa.gov/apod/ap011124.html ] of the planet's rugged surface based on data from the Mariner 10 [ http://nssdc.gsfc.nasa.gov/nmc/tmp/1973-085A.html ] probe that flew by Mercury in 1974 and 1975.
Mercury's Caloris Basin
Title Mercury's Caloris Basin
Explanation Mercury [ http://antwrp.gsfc.nasa.gov/apod/ap950814.html ], the closest planet to the Sun [ http://antwrp.gsfc.nasa.gov/apod/ap950813.html ], has a surface with so many craters it resembles the Earth [ http://antwrp.gsfc.nasa.gov/apod/ap950622.html ]'s Moon [ http://antwrp.gsfc.nasa.gov/apod/ap950707.html ]. The largest surface feature on Mercury [ http://seds.lpl.arizona.edu/nineplanets/nineplanets/mercury.html ] is the Caloris Basin, which resulted from a collision with an asteroid [ http://antwrp.gsfc.nasa.gov/apod/ap951020.html ]. The basin, which is more that 1000 kilometers across, is visible as the large circular feature at the bottom of the above photograph. Similar features, such as the Mare Orientale [ http://antwrp.gsfc.nasa.gov/apod/ap960112.html ], are seen on the Moon. The Caloris Basin gets very hot because it is near the "sub-solar point" - the point on Mercury [ http://bang.lanl.gov/solarsys/mercury.htm ]'s surface that is directly under the Sun [ http://antwrp.gsfc.nasa.gov/apod/ap951004.html ] when Mercury [ http://stardust.jpl.nasa.gov/planets/welcome/mercury.htm ] is closest to the Sun [ http://antwrp.gsfc.nasa.gov/apod/ap951024.html ].
Mercury And The Sun
Title Mercury And The Sun
Explanation Just days before the peak of the Leonid meteor shower [ http://www.arm.ac.uk/leonid/latest.html ], skywatchers were offered another astronomical treat as planet Mercury [ http://pds.jpl.nasa.gov/planets/welcome/mercury.htm ] crossed the face of the Sun on November 15. Viewed from [ http://space.jpl.nasa.gov/ ] planet Earth, a transit of Mercury [ http://sunearth.gsfc.nasa.gov/eclipse/OH/transit99.html ] is not all that rare. The last [ http://antwrp.gsfc.nasa.gov/apod/ap991106.html ] occurred in 1993 and the next will happen in 2003. Enjoying a mercurial transit does require an appropriately filtered telescope, still the event can be dramatic as the diminutive well-done [ http://antwrp.gsfc.nasa.gov/apod/ap991111.html ] world drifts past [ http://www2.astronomy.com/astro/Magazine/Astindex/1999/99Nov/ Transit.html ] the dominating solar disk. This slow loading gif animation [ http://lambic.physics.montana.edu/~handy/trace/mercury/ ] is based on images recorded by the earth-orbiting TRACE [ http://antwrp.gsfc.nasa.gov/apod/ap980515.html ] satellite. The false-color TRACE images [ http://canopy.lmsal.com/schryver/Public/mercury.html ] were made in ultraviolet light and tend to show the hot gas just above the Sun's visible surface. Mercury's disk is silhouetted [ http://chippewa.nascom.nasa.gov/~dcm/transit/transit.html ] against the seething plasma as it follows a trajectory near the edge of the Sun.
