Faster than the speed of light.
Oct 16, 2003 Einstein’s Special theory of Relativity says that information can’t travel faster than the speed of light in a vacuum, and a new experiment carried out by researchers at the University of Arizona seems to support this. By creating what’s called "Gaussian Pulses", experimenters can send light through a medium of pumped potassium gas which causes part of the light wave to travel faster than the speed of light. But when they tried to send information along the wave as discontinuities in the signal, they didn’t travel through faster than the speed of light.
Oct 16, 2003 On Saturday, October 18 the crew of Expedition 8 (Michael Foale and Alexander Kaleri) will blast off in a Russian Soyuz rocket to begin their six-month mission on the International Space Station. Spanish Astronaut Pedro Duque will also be on board, but he will spend only 10-days in space, performing a series of experiments for the European Space Agency. Then Duque and the crew of Expedition 7 will return in the previous Soyuz spacecraft currently docked with the station.
Oct 16, 2003 NASA investigators have come up with four possible reasons why the Comet Nucleus Tour (CONTOUR) mission failed in August 2002. The mission launched in July 2002, and was supposed to visit at least two comets and study their icy nuclei, but something went wrong that caused the spacecraft to disappear from ground tracking stations. The most probably cause of the failure was a structural failure of the spacecraft while its solid rocket motor was firing, but the investigators are also considering a collision with debris, a catastrophic failure of the rocket motor, and loss of the spacecraft’s control systems.
