IO'S CURSE PLAGUES ME AGAIN
As many of noticed, I misidentified Io as Saturn's moon in the last issue of
Universe Today. Of course it's Jupiter's moon, and yes, I should have known
better, but if you look back at a few of the mistakes I've made in the last
few weeks, you'll see an unnerving trend.
In a previous newsletter I said that Io was Jupiter's closest moon. It's not,
that's Metis. I also said that after making a final pass of Io, the Galileo
spacecraft would be plunged into Jupiter later in January. Uh, no, Fraser,
that's going to happen in September 2003.
Sure, mistakes happen - I make my share. But they've all been Io-related.
Coincidence? I think not! So, watch my words carefully when I mention Io;
believe only half of what I say.
I leave it up to you to figure out which half.

ODYSSEY DEPLOYS COMMUNICATIONS ANTENNA
NASA's Mars Odyssey spacecraft deployed its high-gain antenna on
Tuesday night, establishing a high-speed connection between the
spacecraft and controllers back on Earth. Flight controllers
tested the boom to ensure it can communicate with different
locations on Earth and then pronounced the deployment
"successful". Science instruments on the spacecraft are expected
to begin collecting data later this month.
HUBBLE REVEALS BACKWARDS GALAXY
The latest image released from the Hubble Space Telescope shows
a spiral galaxy that seems to be rotating in the wrong
direction. Astronomers expected that galaxy NGC 4622, located
111 million light-years away in the constellation Centaurus,
should rotate counter-clockwise but it actually goes clockwise.
It's believed that the galaxy consumed a smaller companion
galaxy recently which helped reverse its spin.
ENTIRE EARTH IMAGED
NASA has released a new set of photographs which form the most
detailed true- colour image of the entire Earth ever created.
The photographs are taken at a resolution of 1km and include the
land, seas and even clouds and sea ice. Much of the data for
this image was gathered by NASA's Terra satellite, from an
altitude of 700km. An additional image shows actual city lights
superimposed over a darkened version of the photograph.
