1\30 ISS On-Orbit Status 30-01-2003
Part 2 of 2

Today's targets for the CEO (crew earth observations program) were 
Mekong River Delta (pass crossed the entire width of the delta from 
southwest to northeast. Detailed nadir mapping pass requested [looking 
a touch left for sun glint views]), Saigon, Vietnam (nadir pass; ESC 
[electronic still camera]. The city lies inland about 20 km on the 
easternmost river course of the delta), Industrialized SE Africa haze 
(pass paralleled the Great Escarpment: looking left for aerosol 
loadings on the plateau and right for a probably different airmass on 
the coastal plain. Smog loadings should increase with distance north 
from the coast as ISS approached the industrial heartland of the 
Witwatersrand, off-track left ~1.5. [Nadir views of the knot of 
mountains that make up the Kingdom of Lesotho are of great interest 
since major new dams have been built to supply Johannesburg with water 
250 miles to the north]), Delhi, India (looking right of track for the 
city which lies on both banks of the upper Ganges [looking for 
converging pattern of railroads/highways. Crew was also to shoot high 
obliques, looking right, along the Himalayan Mt front, to document the 
remnants of major fog banks that have dominated the Ganges Plain for 
weeks), Mt Cameroon (Dynamic event.  Unusual clear weather in the 
Bight of Benin should make this major volcano visible [the volcano 
drops into the sea from 13000 feet]. Looking right for recent lava 
flows as well as a major collapse canyon on the west side of the 
volcano. There are almost no handheld images of Mt Cameroon), West 
Africa dust (Dynamic event. ISS track crossed over the southern dust 
front of a new outblow of Saharan dust. This plume was centered over 
the Guineas, aligned SW. If possible, crew was to try to document the 
source region[s] of this plume. Since the plume lies further south 
than most, sources probably lie in the zone of disturbed Sahelian 
soils), and Bamako, Mali (looking slightly right of track on the Niger 
River. ESC requested).
