A three-year trek on Mars

NASA has released a movie based on 309 images that were taken by the Mars Exploration Rover Opportunity as it traveled from Victoria crater to Endeavour crater - a 13 mile trek which lasted three years.

Endeavour launch postponed at least a week

The launch of space shuttle Endeavour, originally planned for last Friday, will be delayed at least until following the discovery of problems with a heater on a fuel line.
