Greetings, travelers,
Here’s what’s new at http://spacescience.nasa.gov/ :

More than 20,000 new images of the planet Mars taken by Mars Global
Surveyor are now available in a web-based photo album. Hey, look — if you
squint, you can see a toaster oven!

Galileo has successfully flown past Jupiter’s moon Ganymede, dipping to 809
kilometers above the surface early Saturday, May 20. Galileo is getting
ready for joint science operations with Cassini in December, as Cassini
flies by Jupiter en route to Saturn.

Meanwhile, detailed analysis of Jupiter’s moon Io reveals a colorful,
active world full of surprises, based on new results from Galileo and
Hubble. http://www.jpl.nasa.gov/releases/2000/gllmay182000.html

A new report from the National Research Council of the National Academies
maps out the priorities for investments in astronomy research over the next
decade. This report will factor into funding decisions, both here and at
the National Science Foundation, for years to come. This url will require
some cutting and pasting:

Using our Chandra X-ray Observatory, astronomers have made the first
long-duration x-ray survey of the Hubble Deep Field North. They detected
x-rays from six of the galaxies in the field, and were surprised by the
lack of x-rays from some of the most energetic galaxies in the field.

Europe’s XMM x-ray observatory (with some U.S. hardware on it) was launched
in December. During the current calibration campaign of its science
instruments, XMM has chanced on a sudden alteration in a binary star
system, one containing a likely black hole, whose properties had not
changed for thirty years. It dimmed by a factor of 100, like me after a
long day.
