The surface of the planet Mercury is not without fault. In this case, however, "fault" refers to unusual surface features that are the topic of much speculation. The above fault line is called Santa Maria Rupes, and runs through many prominent craters.
Degas Ray Crater on Mercury
7.12.1996
Like the Earth's Moon, Mercury is scarred with craters, testifying to an intense bombardment during the early history of the Solar System. In 1974, the Mariner 10 spacecraft surveyed this innermost planet up close, producing the only detailed images of its tortured surface.
Unknown Dark Material on Mercury

What is that strange material on Mercury? When flying by Mercury last October, the robotic MESSENGER spacecraft imaged much of the solar system's innermost planet in unprecedented detail. As common in science, new data bring new mysteries.
Pioneer 10: The First 7 Billion Miles
25.08.2001
Q: What was made by humans and is 7.3 billion miles away? A: Pioneer 10 -- and 1997 was the 25th anniversary of its launch. Almost 11 light-hours distant, Pioneer 10 is presently about twice as far from the Sun as Pluto, and bound for interstellar space at 28,000 miles per hour.
Deep Impact Spacecraft Hurtles Toward Comet
16.05.2005
What happens when you crash into a comet? That was a question considered by astronomers when they designed the Deep Impact mission, launched in January. This coming July 4, the Deep Impact spaceship will reach its target - Comet Tempel 1 -- and release an impactor over five times the mass of a person toward its surface.
Sail On Stardust
24.01.2001
Spacecraft on long interplanetary voyages often use the planets themselves as gravitational "sling shots" to boost them along their way. Launched in February of 1999 on a historic voyage to a comet, the Stardust spacecraft is no different.
Surveyor Hops
29.11.2002
This panorama of the cratered lunar surface was constructed from images returned by the US Surveyor 6 lander. Surveyor 6 was not the first spacecraft to accomplish a soft landing on the Moon ... but it was the first to land and then lift off again!

"Safe!" In September 1967 (during regular season play), the Surveyor 5 lander actually slid several feet while making a successful soft landing on the Moon's Mare Tranquillitatis. Equipped with television cameras and soil...
