On July 1st a bright dust cloud spilled out of Hellas Basin, a giant impact crater on Mars' southern hemisphere. The cloud quickly spread and by the Fourth of July was 1100 miles wideabout one-fourth the diameter of Mars itself. Above: These pictures of Mars spanning July 2nd through 6th were captured by Donald Parker of Coral Gables, FL, using a 16-inch telescope. The stubby black arrows indicate the growing cloud. More images: July 1st "The cloud can be seen now through a telescope as small as 6 inches," says Donald Parker, executive director of the Association of Lunar and Planetary Observers (ALPO). "Its core is quite bright." Sign up for EXPRESS SCIENCE NEWS delivery Parker has been tracking the cloud through his own 16-inch telescope. "A red filter helps," he notes. "Even a piece of red or orange gelatin held between the eye and ocular will improve the visibility of the dust."

Mars The Bringer of War Mars is the fourth planet from the Sun and the seventh largest: orbit : 227,940,000 km (1.52 AU ) from Sun diameter : 6,794 km mass : 6.4219e23 kg Mars (Greek: Ares ) is the god of War. The planet probably got this name due to its red color; Mars is sometimes referred to as the Red Planet. (An interesting side note: the Roman god Mars was a god of agriculture before becoming associated with the Greek Ares; those in favor of colonizing and terraforming Mars may prefer this symbolism.) The name of the month March derives from Mars. Mars has been known since prehistoric times. Of course, it has been extensively studied with ground-based observatories . But even very large telescopes find Mars a difficult target, it's just too small. It is still a favorite of science fiction writers as the most favorable place in the Solar System (other than Earth!) for human habitation. But the famous "canals" "seen" by Lowell and others were, unfortunately, just as imaginary as Barsoomian princesses.

Earth Sciences Division The current version of Mars24 is 6.0.3, released 2008-08-05. Mars24 is a Java application which displays a Mars sunclock, a graphical representation of the planet Mars showing its current sun- and nightsides, along with a numerical readout of the time in 24-hour format. Other displays include a plot showing the relative orbital positions of Mars and Earth and a diagram showing the solar angle for a given location on Mars. Mars24 runs on many different types of computers, including Windows, Mac OS X, Linux, and more, but it requires Java 1.5 or better be installed on the computer. The associated MER Spirit/Opportunity Clock Applet requires only Java 1.1.8 and is compatible with many older web browsers, but it does not include Mars Phoenix timing or the sunclock or other graphic displays of Mars24.

Technology Mars World Mythology Dictionary: Mars Home Library World Mythology (European mythology) Next to Jupiter, Mars enjoyed the highest honours at Rome. Exalting military power and glory, the Romans raised this war god far above the status of his Greek counterpart Ares. The Greeks had conceived Ares as an unpopular deity—bloodthirsty, brutal, he was a braggart , even a coward . Mars, on the contrary, was considered the father of Romulus, who built the walls of Rome. The war god also protected farmers and herdsmen, and sometimes used the title Silvanus. March, the month of Mars, possessed a succession of festivals dedicated to the god of war and protector of growth. On 1 March the sacred flame in the shrine of Vesta was relit, and the homes of priests and other sacred buildings were decorated with laurel branches, a tree always associated with Mars. On 14 March there was horse racing in the massive Campus Martius, to which the Roman citizenry thronged. On 23 March holy war trumpets were purified.

20. The Planet Mars (Ares), God Of War. mars, mars Greek Ares, Roman god of war (fourth planet from the sun). Like a badge of blood in the sky, the Red Planet has long stood for the gods of war. http://www.wordsources.info/mars.html

Mars, Mars [Greek: Ares], Roman god of war (fourth planet from the sun). Like a badge of blood in the sky, the Red Planet has long stood for the gods of war. It seems natural that the Greeks named the fourth planet after Ares, since the fourth planet shines with a red color, resembling blood, which is appropriate for the god of war. The Romans identified their god of war, Mars, with the Greek Ares, so now we know the planet as Mars. He was one of the most important of the Roman gods and an entire month of the year was dedicated to him. We still call the third month of the year, March, in his honor. He was also a god of agriculture before becoming associated with Ares. The month was so named because Mars, the patron god of the Romans, was a war-god, and spring campaigns usually began about that time. The Roman year once began with March before it became January. He is characterized as the god who took a savage delight in slaughter, and the hordes of slain upon the battlefield filled him with a fierce joy. In the poems of Homer, there are such epithets as these applied to him: scourge of mortals, piercer of shields, the bloodstained one.
