...bigger potential problem is the loss of precise control over station orientation. Part of the reason for Atlantis's current visit is to install a new pair of solar arrays, just two of several such reflective wings that help supply the station with power. But collecting solar energy means being able to keep yourself pointed toward the sun, not so easy if you're drifting off center. The computers also help orient the station to avoid space debris and move into position for docking with the shuttle or arriving cargo ships. For now, the shuttle's thrusters and the station...
...short- and long-term energy solution. As U.S. vehicles burn through 9 million bbl. of gasoline a day, cornfield Cassandras fear that the home-brewed replacement may be only a pricey stepping-stone to a new generation of more efficient, lower-cost power sources like other biofuels, solar cells, wind and ethanol made from farm waste or other sources. Brazil, for instance, brews sugarcane-based ethanol, which is more efficient than corn-based...
...Solar power is now three to four times more expensive than fossil-fuel energy, but the ultra-efficient black silicon chip could reduce that cost substantially...
...won’t just transform the production of solar power. It also could make pollution detectors much more sensitive, and it could find its way into home appliances ranging from computer chips to flat-screen televisions...
...Charbonneau searches for extrasolar planets by looking for signs of planets crossing in front of stars outside our solar system. Through a series of NASA-funded telescopes located in southern California that monitor 10,000 stars at a time, Charbonneau and his researchers scour the data, measuring the brightness of the stars. If a star is dark, it could be due to an eclipse from a planet in orbit around...
