Looking Closely at 'Yuri' |
| Original Caption Released with Image |
This picture from the microscopic imager on NASA's Mars Exploration Rover Opportunity is a mosaic of a target called "Gagarin" on a rock referred to as "Yuri." Opportunity brushed the target with the rock abrasion tool during the rover's 401st martian day, or sol, (March 10, 2005) and then took the individual images that are combined into this mosaic. The rock abrasion tool ground into the same target on the following sol. The circle from which the tool's wire brush has scoured dust off the rock surface is about 5 centimeters (2 inches) in diameter. This rock is near the rim of "Vostok" crater. Yuri Gagarin was the first man to orbit Earth. The Russian cosmonaut's spacecraft was named Vostok NASA/JPL/Cornell/USGS1. |

Springtime Dunes, 2004 |
| Original Caption Released with Image |
12 April 2004 Today is April 12, 2004, the 43rd anniversary of the first human flight into space (Yuri Gagarin, 1961) and the 23rd anniversary of the first NASA Space Shuttle flight (Columbia, 1981). Meanwhile, on Mars, spring is in full swing in the martian northern hemisphere. With spring comes the annual defrosting of the north polar dunes. This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image, acquired on April 7, 2004, shows a field of small barchan (crescent-shaped) dunes covered with the remains of wintertime frost. The dark spots around the base of each dune mark the first signs of the spring thaw. The sand in these dunes is dark, like the black sand beaches of Hawaii or the dark, sandy soil of the rover, Opportunity, landing site, but in winter and spring their dark tone is obscured by bright carbon dioxide frost. This picture is located near 75.9°N, 45.3°W, and covers an area about 3 km (1.9 mi) across. Sunlight illuminates the scene from the lower left. |
