* First Odyssey Photos Released
* Cooling Problem Threatens Shuttle Mission
* Shuttle on its Way to Upgrade Hubble
* Ariane 5 Launches Envisat Successfully
FIRST ODYSSEY PHOTOS RELEASED
It's only the first few photographs from Mars Odyssey, but
scientists are already excited about what the spacecraft has
turned up on the surface of Mars. Odyssey, which began mapping
the planet last week, has detected significant amounts of
hydrogen near the planet's south pole. Scientists believe this
hydrogen is evidence of water ice - and not just surface frost,
but a large quantity of frozen water.
COOLING PROBLEM THREATENS SHUTTLE MISSION
Space shuttle managers are debating whether to end the space
shuttle Columbia's mission to upgrade the Hubble Space Telescope
because one of its two cooling systems isn't working properly.
Although the shuttle is equipped with two redundant systems,
NASA flight rules demand that the shuttle return to Earth if
either completely fail - right now, one is just blocked and not
working at full capacity. Mission controllers will make a
decision to scrub the mission or keep going Friday evening.
SHUTTLE ON ITS WAY TO UPGRADE HUBBLE
The space shuttle Columbia roared into the Florida sky Friday
morning, beginning an 11-day mission to upgrade the Hubble Space
Telescope. The mission had originally been delayed a day because
of unusually chilly weather, but everything was "go for launch"
this morning. Columbia lifted off at 1122 GMT (6:22am EST) and
is scheduled to meet up with the telescope early Sunday
ARIANE 5 LAUNCHES ENVISAT SUCCESSFULLY
After much anticipation, an Ariane 5 rocket blasted off from
Kourou, French Guiana last night, carrying the European Space
Agency's Envisat environmental monitoring satellite into an
800km orbit. Once it reaches its final orbit, the 8000 kg
Envisat will observe the Earth's environment using ten
instruments which measure the state of the land, ocean, ice
cover and atmosphere. This is the first launch of an Ariane 5
since a problem last July that placed two satellites into
