Nine Galileo images of the Jovian moon Europa taken in December of 1997 have recently been released by the National Aeronautics and Space Administration's Jet Propulsion Laboroatory. The images support the theory that slush or liquid water exists below the surface of the satellite. The site contains links to the images (available in several resolutions and formats) and descriptive captions, along...

The NASA Jet Propulsion Laboratory has devised a remarkable new type of sensor that could revolutionize the way scientists gather data. A Sensor Web is a network of many individual sensors that are about the size of a ping-pong ball. By themselves, they collect a single measurement-like temperature or humidity. But an entire Sensor Web can be spread out over a very large area and collect vast...

Scheduled for launch in 2003, two NASA rovers will set out to explore Mars and determine whether water ever existed on the planet. This is the home page of the Mars rovers, and it has a great deal of information about the specifications and technology of the missions. Detailed descriptions of the scientific instruments equipped on each rover are provided. Color diagrams show the main components of...
