NASAs 'Curiosity' Search for Life Targets Water-Altered Rock. This rock's composition is unlike any other Opportunity has investigated during nine years on Mars -- higher in aluminum and silica, lower in calcium and iron.
"Based on our current solar-array dust models, we intend to reach an area of 15 degrees northerly tilt before Opportunity's sixth Martian winter," said JPL's Scott Lever, mission manager. "Solander Point gives us that tilt and may allow us to move around quite a bit for winter science observations. " Northerly tilt increases output from the rover's solar panels during southern-hemisphere winter. Daily sunshine for Opportunity will reach winter minimum in February 2014. The rover needs to be on a favorable slope well before then. What is the relationship between the moon and the tide? a WebQuest.

" The gruff inspector snarled as he spoke to your team of detectives. "For a long time people have been blamin' things on the moon! The Moon l Phases, Orbit and distance from the Earth. The Moon is the only natural satellite of Earth: orbit: 384,400 km from Earth diameter: 3476 kmmass: 7.35e22 kg History of The Moon Called Luna by the Romans, Selene and Artemis by the Greeks, and many other names in other mythologies.
The Earth's Moon. The Earth's Moon NASA.
The Earth's one natural satellite, the Moon, is more than one quarter the size of Earth itself (3,474 km diameter). Because of its smaller size, the Moon's gravity is one-sixth of the Earth's gravity, as we saw demonstrated by the giant leaps of the Apollo astronauts. While there are only two basic types of regions on the Moon's surface, there are many interesting surface features such as craters, mountain ranges, rilles, and lava plains.
The structure of the Moon's interior is more difficult to study. The Moon's top layer is a rocky solid, perhaps 800 km thick. Solar System, Solar System Information. Our Cosmic Neighborhood From our small world we have gazed upon the cosmic ocean for thousands of years.

Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2002 November 14 Explanation: This stunning image shows remarkable and mysterious details near the dark central region of a planet-sized sunspot in one of the sharpest views ever of the surface of the Sun. Just released, the picture was made using the Swedish Solar Telescope now in its first year of operation on the Canary Island of La Palma. Along with features described as hairs and canals are dark cores visible within the bright filaments that extend into the sunspot, representing previously unknown and unexplored solar phenomena.
