ISS On-Orbit Status 27 Jun 2003

Part 2 of 3

Today's CEO (crew earth observation) targets, limited in the current
XPOP attitude by flight rule constraints on the use of the Lab
nadir/science window, and including the targets of the Lewis & Clark
200-year memorial locations, were Lisbon, Portugal (nadir pass),
Berlin, Germany (nadir pass. Good weather persists.  Panoramas of the
North European plain and Baltic Sea also possible), Gulf of Maine
plankton (pass along the coast:  look right into the gulf for any
discoloration in the water due to plankton blooms), Tucson, Arizona
(major wildfire coming under control.  High satellite images of the
long smoke plume are making the news.  A handheld image would be
posted on the web immediately to complement these), Albuquerque, New
Mexico (looking right for a view of the urban region, sited along the
easy-to-see Rio Grande), Montana sites (LEWIS & CLARK SITES:  A swath
of detailed nadir views should have captured several close-spaced
sites along the Missouri River.  Here in the spring of 1805, the
explorers opted to use the Missouri. By taking the Yellowstone their
journey could have been shortened by two months), Baghdad, Iraq (good
pass along the Zagros mountain front:  looking right for views of
cities and the Mesopotamian plain), Western Mediterranean Haze (haze
loadings are increasing left of track in the Genoa/Pisa region of
northern Italy [visibilities reduced to 1-3 mi.].  Then Rome
immediately left of track.  Then Etna volcano immediately right),
Angolan Biomass Burning (offshore flow continues:  the crew had an
ideal vantage point on this southeasterly pass to document aerosolic
haze from the subcontinentwhich is mainly smoke from biomass burning,
but now after several days of this weather pattern, includes
industrial haze from the distant Witwatersrand line of cities.
Images of this haze phenomenon are of great interest.  Okavango swamp
delta appears as a dark green "hand" in the dun colors of the desert
just left of track), San Francisco, California (panorama of The Bay
region off right of track), and Los Angeles, California (nadir pass
over the basin). CEO images can be viewed at the websites
