...year, 2.3 billion-mile odyssey will culminate Thursday when the Galileo spacecraft swings into orbit around Jupiter. "The accuracy of this is really amazing," says TIME's Leon Jaroff. "Scientists were able to make incredibly precise calculations to place Galileo in exactly the right place, using Venus and the Earth in a 'crack-the-whip' maneuver to boost the probe's velocity to give it sufficient speed to make it all the way to Jupiter." Also Thursday, a smaller probe released from Galileo 147 days earlier will enter Jupiter's atmosphere. "There won't be any dramatic pictures, just...
Data transmission will be considerably slowed because the probe's main antenna has failed to open, forcing engineers to rely on a much slower backup antenna. Jaroff says the problem can be traced back to 1987, when Galileo's launch was delayed by the Challenger explosion. "After the Challenger, they trucked the probe back to California to be put into storage. What engineers think happened is that the vibrations of the transcontinental trip may have worn out some of the lubricants that should have helped the antenna to open." Because of the delay, the spacecraft will only transmit hundreds...
Researchers at the Los Alamos National Laboratory announced they have developed a flexible superconducting tape that can carry 100 times more current than similar materials. There are two key developments here, says TIME science contributor Leon Jaroff. One is flexibility. Previous materials had been brittle, and snapped easily at the extremely low temperatures necessary for superconductivity. The other key is that the new material conducts electricity with no resistance at the temperature of liquid nitrogen, minus 320 degrees Fahrenheit. This makes it much cheaper to maintain and use than other superconducting materials that need to be cooled to a much...
