Things got a little hectic around here, and this is the first message to
this list in almost 2 weeks. Sorry! Here's the recent news at
Scientists catching cosmic rays have tightened the constraints on the
evolving theory of how atoms travelling at nearly the speed of light are
produced and strewn across the Universe through supernovae. These results
come from our Advanced Composition Explorer spacecraft.

One longstanding mystery of the sun is why its outer atmosphere - the
corona - is 200 times hotter than its surface. Now, a trio of scientists
says it's because the corona is heated by incessant mini-explosions, called
microflares. Nice story at
We have taken all appropriate actions to mitigate issues raised regarding
the Inertial Upper Stage and have decided to proceed with preparing
Inertial Upper Stage-27, beginning today, for launch of the Chandra X-ray
Observatory on STS-93 no earlier than July 22. You can read more, and
follow future preparations for the launch of Chandra, the "x-ray Hubble",
An impact basin deep enough to swallow Mount Everest and surprising slopes
in Valles Marineris highlight a global map of Mars that will influence
scientific understanding of the red planet for years. The topographical
map is just the latest output from Mars Global Surveyor.

The Hubble Space Telescope Key Project Team announced last week that it has
completed efforts to measure precise distances to far-flung galaxies, an
essential ingredient needed to determine the age, size and fate of the
universe. "Before Hubble, astronomers could not decide if the universe was
10 billion or 20 billion years old," said team leader Wendy Freedman.
Combining Hubble's new measurement with estimates for the density of the
universe, the team determined that the universe is approximately 12 billion
years old. Press release and images at
A second test of Deep Space 1's Remote Agent experiment, a package of
onboard software designed to run parts of the spacecraft automatically
without intervention from the ground, has been completed. All Remote Agent
objectives have now been met.

Finally, there seems to be a big wave of new subscribers to this list
today. I'm guessing that the list got some publicity somewhere. Can any
of you new subscribers confirm that for me? I'm just curious, and would
like to know where my audience is coming from. Thanks!
