Astounding! Mars rovers, Spirit & Opportunity (expected lifespan of 90 days from Jan 3 '04), roving on into 5 yrs
(quote)
The US space agency's (NASA) Mars rovers are celebrating a remarkable five years on the Red Planet. The first robot, named Spirit, landed on 3 January, 2004, followed by its twin, Opportunity, 21 days later. Their longevity in the freezing Martian conditions has surprised everyone.
The unmanned rovers Spirit and Opportunity are showing serious signs of wear after an astounding five years roaming Mars, U.S. space agency officials say. Scientists initially thought the remote-controlled machines would last only three months in Mars' freezing climate, said John Callas, rover project manager at the National Aeronautics and Space Administration's Jet Propulsion laboratory in Pasadena, Calif.
"These rovers are incredibly resilient considering the extreme environment the hardware experiences every day," Callas said, noting information sent by the rovers have proved water existed on Mars billions of years ago. read more »
10th anniversary of the first launched module of the International Space Station (ISS)
(quote)
Last month marks the 10th anniversary of the first launched module of the International Space Station (ISS). The module Zarya was lifted into orbit on November 20th, 1998 by a Russian Proton rocket lifting off from Baikonur, Kazhakstan. In the decade since, 44 manned flights and 34 unmanned flights have carried further modules, solar arrays, support equipment, supplies and a total of 167 human beings from 15 countries to the ISS, and it still has a ways to go until it is done. Originally planned to be complete in 2003, the target date for completion is now 2011. Aside from time spent on construction, ISS crew members work on a good deal of research involving biology and physics in conditions of microgravity. If humans are ever to leave the Earth for extended periods, the ISS is designed to be the place where we will discover the best materials, procedures and safety measures to make it a reality.
Nobel Prize’08: Japan attracts top talents. Share chemistry prize, split physics award with American scientists

The Nobel Prize (Swedish: Nobelpriset) is a Swedish prize, established in the 1895 will of Swedish chemist Alfred Nobel; in his will, he used his enormous fortune to institute the Nobel Prizes. The synthetic element nobelium was named after him. It was first awarded in Peace, Literature, Chemistry, Physiology or Medicine, and Physics in 1901. An associated prize, The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, was instituted by Sweden's central bank in 1968 and first awarded in 1969.
Bread-loaf-sized satellite Firefly on lightning & gamma rays, most powerful natural particle accelerator in atmos.
(quote)
Firefly is a new mission to study lightning and gamma rays with CubeSats, small satellites in the shape of a cube.
Firefly, it's called, this new small satellite mission sponsored by the National Science Foundation (NSF). It's designed to help solve the mystery of the most powerful natural particle accelerator in Earth's atmosphere: TGFs, or terrestrial gamma-ray flashes. TGFs likely result from thunderstorms.
The mission is the second project under the new NSF CubeSat program. A CubeSat satellite, about the size of a loaf of bread, consists of three cubes attached end to end in a rectangular shape.

Solar Energy: Spain takes lead with government commitment, enforces building code, erects more solar power plants
(quote)
As researchers continue to explore new ways to promote and improve solar power, Spain forges ahead with plans to build concentrating solar power plants, establishing the country and Spanish companies as world leaders in the emerging field. At the same time, the number of installed photovoltaic systems is growing exponentially, and researchers continue to explore new ways to promote and improve solar power. This is the seventh in an eight-part series highlighting new technologies in Spain and is produced by Technology Review, Inc.’s custom-publishing division in partnership with the Trade Commission of Spain.
World's first biofuel-powered flying car - Parajet Skycar drives like a car and flies like a plane
(quote)
To Timbuktu by flying car: it sounds the most unlikely journey on earth; a sci-fi voyage from the pages of Jules Verne. But this is no fantasy. The car really flies. And the journey will become reality early in the new year when two explorers set off from London in a propeller-powered dune buggy heading for the Sahara.
The seed of this improbable adventure was sown four years ago when Gilo Cardozo, a paramotor manufacturer, had a eureka moment. For those not familiar with paramotors, picture a parachutist with a giant industrial fan strapped to his back, which provides forward motion and boosts lift for the parachute - or wing - during takeoff. Cardozo’s brainwave was to attach a car to the fan. “I started making a paramotor on wheels that you sit on and take off and it suddenly occurred to me, ‘Why not just have a car that does everything?’” recalls Cardozo, whose Wiltshire-based company Parajet built the paramotor that the adventurer Bear Grylls used to fly near Everest last year.
World’s first, most ambitious, working wave farm, now generating electricity for 1,500 homes: Pelamis in Portugal
(quote)
Three red snakelike devices bobbing in the waves three miles (4.8 kilometers) off the coast of Agucadoura, Portugal, represent the first swell of what developers hope will be a rising tide of wave power projects. These big metallic sea snakes bobbing in the ever-restless waves of the North Atlantic are generating electricity for over a thousand homes on shore. The world’s most ambitious, working wave farm for generating electricity, it is part of Portugal’s national effort to become energy self-sufficient as Denmark has done since the 1970s oil crisis. Portugal is not a wealthy nation and has no coal or petroleum. So wind and water and sunshine are their favored sources of energy. Portugal is also one nation encouraging local cities to become zero emission communities.
Prefab, high-concept and green: an eco-house that’s low-maintenance, small-carbon-footprint and also a work of art
(quote)
Thomas Small is an accomplished cook, so it’s important for him to try new and exotic ingredients every now and then. When it came to the construction of his eco-friendly house, that’s exactly what his architects gave him. After all, crushed sunflower husks and shredded blue jeans don’t sound like typical building blocks. But in the world of green design, such ingredients are not rare. So now, Mr. Small and his wife, Joanna Brody, along with their two very young children and a pair of large French Briard dogs, share a prefabricated urban building that has become an example for others looking for creative ways to go green.
