...faces of SOHO's solar panels tilt more and more toward the sun, controllers are alternately charging the batteries and using them to warm SOHO's slushy on-board hydrazine fuel, which nearly froze during the craft's dormancy. The hydrazine, when fully thawed, will be used to fire thrusters in a series of brief burns. That procedure should halt SOHO's spin, stabilize the observatory and face its solar panels directly toward...
...example, Daimler plans to use methanol in its fuel cell cars and extract the hydrogen on-board. But experts have said that it will also be difficult to supply methanol to customers...
Slide the REX into a notebook's PCMCIA slot or a special desktop docking station and all your data is transferred in seconds. Despite the lack of on-board data entry, the sheer size of the REX has made it a big hit. Look for it to be a big seller in the coming year...
...between Earth and Mars, it's impossible for controllers to stop Sojourner from running into an obstacle or over a cliff. The car thus moves excruciatingly slowly--just 2 ft. per minute--reducing the likelihood that it will stumble into trouble. Built-in gyroscopes serve as a sort of on-board vestibular system, helping the rover feel for bumps and potholes; a tracery of five laser beams helps it feel for obstructions. In addition, when Sojourner ventures out it will transmit a regular, pulselike signal back to the lander, which will serve as a sort of vehicular EKG, constantly confirming...
...rocket's first stage engines 48 seconds after launch, Russian Space Agency officials said. No injuries were reported. It was the twenty-eighth launch and seventh failure of a Zenit-2 since 1985. For Russia, the disaster is the latest in a string of setbacks, which have included fires on-board Mir and delays in the construction of critical components for the international space station. But TIME's Jeffrey Kluger reports that such difficulties are to be expected from an aging and underfunded space program. "The lack of funding has led to a weaker infrastructure in which the Mir used...
