...twice a day. How about generating electricity from floating pistons on the ocean? Unlike dams, floating pistons would be friendly to marine life; they would not silt up bays and would be far less expensive to construct. Just north of Maine, in the Bay of Fundy, a moon tide can be 15 m. If intermittent vibrations on a bridge are being used to generate 20 microwatts to 120 microwatts, why not think bigger? Robert F. Bourque, North Port, Florida...
This spring three of the rugged ships stand out from the rest. Near Saturn, the Cassini orbiter, launched by the Jet Propulsion Laboratory, just executed a dramatic dive through an icy geyser that reaches 950 miles (1,530 km) into space from the Saturnian moon Enceladus, and there are plans to follow that up with even higher-risk maneuvers. In May NASA's Phoenix Lander will set down in Mars' arctic region in search of water ice. And later this month NASA and the European Space Agency will retire their Ulysses solar surveyor after a 17-year mission that...
Before the orbiter attempts that maneuver, it will execute two flybys of the moon Titan, whose opaque orange atmosphere has been increasingly pierced by the spacecraft's radar. And this summer Cassini will make an unusually high orbit above Saturn's massive B ring, promising unique images of the ring, spread like an immense halo around the planet. The ship will also have the rare opportunity to observe the sun cross the plane of the ring from south to north, literally shedding light on the B ring's complex particle structure. "We want to know what a particle would look...
...diminishing power supply means the Ulysses mission ends on March 30, but the textbook rewrites will go on as fresh ships continue to take the place of old ones. The Lunar Reconnaissance Orbiter (LRO), which will launch later this year, will conduct the most comprehensive surveys of the moon the U.S. has ever attempted, using cameras that can spot an object as small as a football. The mission will help scout for landing sites, as NASA is holding fast to its plans to return astronauts to the moon by 2020. LRO will also hunt for signs of water...

Unlike dams, floating pistons would be friendly to marine life; they would not silt up bays and would be far less expensive to construct. Just north of Maine, in the Bay of Fundy, a moon tide can be 50 ft. If intermittent vibrations on a bridge are being used to generate 20 microwatts to 120 microwatts, why not think bigger...
