WHERE'S ALL THE ANTIMATTER?
Experiments at the Fermi Particle Accelerator, located near
Chicago, have begun to provide clues as to why the universe
is mostly made up of matter, instead of anti-matter. If the
numbers had been equal, the universe would have annihilated
itself in a flash of energy.
SUN'S HEAT PUSHES asteroids OUT OF THEIR ORBIT
Because of their irregular shapes, asteroids are warmed
unevenly by the Sun. This force, called the 'Yarkovsky
effect' is thought to slowly push asteroids out of their
regular main-belt orbit. Astronomers believe that some of
these strays are picked up by Mars' gravity and hurled
into Earth-crossing orbits.
STARDUST ENTERS SAFE MODE
During testing and transmission of its first few images from
space, Stardust's main computer shut down non-critical systems,
and entered safe mode. The spacecraft resumed normal operations
later in the day when NASA engineers re-established contact.
ORBITAL SCIENCES SIGNS CONTRACT FOR TVSAT DEAL
B-SAT, Japan's Broadcasting satellite System Corporation recently
awarded the contract to Orbital Sciences to build and launch
two GEO orbit satellites.
