...on Mars?
quote:
Sere and silent Mars is no dead planet, but in many ways its surface is dynamic and ever-changing, with gullies actively forming, rocks tumbling and asteroids blasting fresh craters in the sand, new images released Tuesday show.
Even the planet's climate appears to be changing -- perhaps indicating that Mars, like Earth, is undergoing a period of global warming, said scientists interpreting the images.
The pictures, taken by high-resolution cameras aboard the 8-year-old orbiting Mars Global Surveyor spacecraft, "reveal a planet that can change not only in the mind-boggling millions or billions of years, but on the order of merely years or decades," said Michael Meyer, chief scientist of NASA's Mars Exploration Program in a teleconference Tuesday from the Jet Propulsion Laboratory in Pasadena. |
