Such structures are not particularly indicative of alien life. And other, vaguer faces dot the surface of the red planet. The Mars Express images captured a skull-shaped mesa. A lava flow pattern on the large volcano Alba Patera looks a great deal like the popular Muppet Kermit the Frog. Viking captured several other intriguing images, including the Galle crater in the southern highlands, boasting a curved mountain range and two mountain clusters that create the appearance of a smiley face. Both the Global Space Surveyor and the Mars Express captured enough data to create a three-dimensional look at the fascinating formation.Īlthough one of the most popular landmarks on Mars, the face is by no means the only group of rocks to lie in a visually pleasing configuration. The results revealed that there was nothing unique about the structural formation of the face itself it resembles its neighboring landforms. Other mesas are scattered across the Cydonia region, and the orbiters have measured them while circling over the area. It likely formed from a combination of landslides and collected debris. The rocky outcropping that creates the illusion is approximately a mile across and bears a resemblance to buttes or mesas from the American West. But at least one important revelation has already come out of his research.A close-up view (from above) the Martian Happy Face, Crater Galle, in false-color. Tanaka says he suspects that scientists around the world will make use of it. The new Mars data is already available through the geologic survey’s website, and Dr. “We were drafting maps by hand, using ink,” he said. Tanaka, who was a junior author on the original 1987 Mars map, recalled trying to chart the Martian surface before the digital age. “It’s based on a lot more data than the previous Mars map.”ĭigital mapping technology also played an important role in the research.

This tool, among others, “greatly improved topographic mapping accuracy of the planet,” said Kenneth L. The Planet Express crew's latest mission is to deliver a crate to Professor Farnsworth 's office at Mars University. By measuring the time it took to bounce a laser beam off the Martian landscape, the researchers estimated the heights of peaks and the depths of valleys. One important instrument was the laser altimeter, which could fire up to 600 million laser beams at a planet’s surface. “It was during that period that more water would have been around, which is one of the key aspects of the origin of life.”
“We are disproportionately interested in the early part of Martian history,” said David Beaty, the chief scientist for the Mars Exploration Directorate at the Jet Propulsion Laboratory in Pasadena, Calif., who was not involved in the research. Because the map highlights the location of the oldest rocks on Mars, it could help future missions chart a course for these areas. The new map shows that ancient rock - dating back billions of years ago, when Mars’s environmental conditions might have closely resembled Earth’s- exists in many more locations than previously thought. Now, scientists at the United States Geological Survey have used that data to create an updated map of the entire Martian surface.
Since then, four additional orbiters with superior imaging capabilities have journeyed into Martian orbit, collected data and transmitted their findings back to Earth. The last major effort in Martian cartography was published in 1987, scraped together from the early Viking probes’ scant images and datasets. The red planet is long overdue for a new one. What they have needed is a global geologic map. But to really understand the Martian landscape, scientists need to look at the entire surface. What really lies across the surface of Mars? Rovers have scurried about the red planet for years, drilling, scooping and analyzing for signs of life, past or present.
