For the last
three years, the grating experiments on Chandra and
|
|
|
XMM-Newton have
been providing magnificent spectra of nearly all
|
|
|
classes of
cosmic X-ray sources. In most cases,
these are the very first
|
|
|
high resolution
X-ray spectra we have had available.

As an
introduction to this meeting, I thought it might be fun to look
|
|
|
back to where we
came from, to get to where we are today in this field.

I have chosen
three snapshots in time:
|
|
|
|
– |
Then:
Summer 1980 - I was driving across the U.S. (Berkeley to Boston).
|
|
|
We had results
from Uhuru, Ariel V, OSO 8, HEAO 1, and were just
|
|
|
starting to get
results from Einstein.
|
|
|
|
– |
Then
Again: Summer 1995 - I was driving across the U.S. (Berkeley to
|
|
|
NY). EXOSAT, BBXRT and ROSAT had flown in the
interim. We were
|
|
|
starting to get
results from ASCA.
|
|
|
|
– |
Now:
Summer 2002 - Chandra has been up for three years, XMM-
|
|
|
Newton for 2
1/2. Astro-E tragically lost, but
Astro-E2 in development.
