Its interior shows a surface which is shaped by 'aeolian' (wind-caused) activity as seen in numerous dunes and dark dust devil tracks which removed the bright dusty surface coating. The 'face' was first pointed out in images taken during NASA's Viking Orbiter 1 mission. Galle (1812-1910), is informally known as the 'happy face' crater. Several parallel gullies, possible evidence for liquid water on the Martian surface, originate at the inner crater walls of the southern rim.Ĭrater Galle, named after the German astronomer J.G. The images of the 230 km diameter impact crater are mosaics created from five individual HRSC nadir and colour strips, each tens of kilometres wide.Ī large stack of layered sediments forms an outcrop in the southern part of the crater. The images show Crater Galle lying to the east of the Argyre Planitia impact basin and south west of the Wirtz and Helmholtz craters, at 51° South and 329° East. The HRSC obtained these images during orbits 445, 2383, 2438, 24 with a ground resolution ranging between 10-20 metres per pixel, depending on location within the image strip. Mars News and Information at MarsDaily.These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, show the Galle Crater, an impact crater located on the eastern rim of the Argyre Planitia impact basin on Mars.
The image's ground resolution ranges from 10 meters to 20 meters (32.5 feet and 65 feet) per pixel, depending on the image strip – although technicians reduced the resolution to 50 meters (162.5 feet) for use on the Internet. They also derived the color from three separate HRSC image-data channels during the overlapping passes. Conventional wisdom holds that the markings inside. A large meteor impacted the Martian surface to form the crater. Such markings were originally discovered in the late 1970s in pictures taken by the Viking Orbiter. Face on Mars equivalents offered RIGHT: Happy-face crater, 1999, Mars by NASA. The Martian crater Galle has internal markings reminiscent of a smiley face symbol.
Each pass produced an image strip covering an area tens of kilometers wide. Explanation: Even Mars can put on a happy face. Ground technicians compiled the single image from five separate passes using the spacecraft's High Resolution Stereo Camera. The crater's interior shows a surface shaped by Aeolian, or wind-caused, activity manifested in numerous dunes and dark dust-devil tracks which removed the bright dusty surface coating. Two years into his trademark, Loufrani secured a lucrative partnership with the candy company Mars, which printed the smiley face on its chocolate Bonitos (the forerunner to M&Ms in Europe). The face was first noticed in images taken during NASA's Viking Orbiter 1 mission in the late 1970s. Franklin Loufrani (photo illustration by The Hustle). Galle (1812-1910), is known informally known as the 'happy face' crater.

The image shows a large stack of layered sediments forming an outcrop in the southern part of the crater. Mars Express captured this image showing the Galle Crater, a feature 230 kilometers (143 miles) wide located on the eastern rim of the red planet's Argyre Planitia impact basin.Ĭrater Galle lies to the east of Argyre Planitia and southwest of the Wirtz and Helmholtz craters, at 51 degrees South latitude and 329 degrees East longitude. The Galle Crater on Mars displays a distinctive happy face. MARSDAILY Mars Express Captures Happy-Face Crater In fact, the original Mars Happy Face photo was featured on that site on March 15, 1999.
