Fuel Leak Delays Titan Launch

Aug 14, 2003 - The launch of a Titan 4B rocket was delayed after 200 litres of toxic nitrogen tetroxide propellant spilled out and created a dangerous gas cloud. Fortunately, none of the workers were injured by the cloud, and it dissipated before it reached the adjacent Kennedy Space Center. It's unknown when the Titan rocket will be ready again to launch its cargo of a National Reconnaissance Office satellite. Investigators are still determining what caused the accident.

Gamma Ray Bursts May Propel Fast Moving Particles

Aug 13, 2003 - Astronomers believe that gamma-ray bursts, the most powerful explosions in the Universe, may be generating ultrahigh-energy cosmic rays, the most energetic particles in the Universe. These cosmic rays have baffled Astronomers because they're moving faster than if they were thrown out of a supernova. Evidence gathered by NASA's de-orbited Compton Gamma-Ray Observatory showed that in one instance of a gamma ray burst, these high-energy particles dominated the area giving a connection between them, but this is hardly enough evidence to say they're conclusively linked.

SCISAT Successfully Launched

Aug 13, 2003 - The Canadian Space Agency's SCISAT satellite was successfully launched Wednesday morning on board a Pegasus XL rocket. The L-1011 carrier aircraft deployed the three-stage Pegasus rocket at 0210 GMT (22:10 EDT Tuesday) at 12,000 metres, which then blasted up to a 650 km polar orbit. During its two-year mission, SCISAT will help a team of international scientists improve their understanding of ozone layer depletion - especially over Canada and the Arctic.
