POLAR LANDER FINE-TUNES FLIGHT PATH
The Mars Polar Lander fired its manoeuvring engines for 30 seconds
to make a minor flight correction on its way to the Red Planet. The
lander increased its velocity by 2.3 meters per second, and will
actually arrive an hour earlier than planned at Mars' South Pole
on December 3rd.
BLACK HOLE COLLISION MODELED
Physicists at the Albert Einstein Institute are working on a computer
simulation of what would happen in the grazing collision of two black
holes. They hope to use the simulation to predict the kinds of
gravitational waves they should detect when such a collision actually happens.
AS SOLAR MAXIMUM APPROACHES, EXPECT DISRUPTION
Solar activity follows a predictable 11-year cycle, and the next peak
will happen in mid-2000 and last for a year or two. With more satellites
in orbit than ever before, researchers are concerned that the constant
stream of solar ejecta will interfere with their sensitive instruments.
AUSTRALIAN FOSSIL AIDS SEARCH FOR MARTIAN LIFE
Chemical traces of fossilized bacteria over 3.46 billion years old
have been found in rocks from Australia. Researchers hope to use
these remnants as a way to research the possible evolution of life on
Mars by comparing the structure of the fossils to those found in the
meteor that supposedly contains fossils of Martian life.
CASSINI CAPTURES Moon IMAGES AS IT PASSES EARTH
During its flyby of the Earth, NASA had an opportunity to test
Cassini's imaging system - they pointed it at the Moon and captured
a detailed series of images. Cassini was approximately 80 minutes
away from its flyby, and 377,000 kilometres away from the Moon when
it took the pictures.
EXTRASOLAR STARQUAKES DISCOVERED
Declared a launch failure when its cooling Hydrogen leaked, the
Wide-Field Infrared Explorer (WIRE) satellite has found a new
lease on life. Using its secondary telescope Astronomer Dr. Derek
Buzasi has discovered the first starquakes on a star other than
64 CASES OF WIRING FAILURE
NASA technicians inspecting the Space Shuttle fleet have found
a tremendous number of wire defects on all of the shuttles. 38 have
been found on the Endeavour and 26 on the Discovery. The inspectors
have 100 miles of wiring to explore on the fleet. Their next
launches have been delayed until the repairs are complete.
HUBBLE CAPTURES Galaxy QUARTET
Using the Wide Field and Planetary Camera 2, the Hubble Space
Telescope recently captured striking images of a quartet of
galaxies known as the Hickson Compact Group 87. The Galaxies
orbit one another, over a timespan that takes hundreds of
millions of years.
JUPITER'S MOONS GATHER SIGNIFICANT DUST
During close flybys of the various Jovian moons, the Galileo spacecraft
picked up increased levels of microscopic particles of dust crashing
into its ionisation dust detector. The velocity of the dust is low,
eading researchers to believe they originate from the moons
themselves - a constant hail of dust impacting the surface and
being ejected back into space.
KOREAN satellite LAUNCHES
A Korean Koreasat 3 telecommunications satellite was launched on board
an Ariane 42P rocket from the European launch site at Kourou in French
Guiana. The launch was delayed one day because of a minor technical glitch
which was resolved in time for a smooth lift-off Sunday.
PROSPECTOR CRASH DIDN'T CREATE A DUST CLOUD
After first proposing a crash-landing of the Lunar Prospector spacecraft
into the Moon's South pole in search of water, professor David Goldstein
from the University of Texas announced that no dust cloud had been created.
This lack of dust doesn't completely rule out the search for water after
the explosion, however.
