2\13 ISS On-Orbit Status 13-02-2002
Part 2 of 2

Progress Water Delivery: The "Rodnik" water storage system of a 
Progress M vehicle can deliver 420 kg H2O. The M1 "tanker" version had 
the Rodnik tanks removed and replaced with propellant tanks, but it 
can deliver water in portable EDV containers in the pressurized Cargo 
Module, each EDV holding 22 kg of water. It is generally assumed that 
approximately 10 EDV's can be loaded into a Progress (M and M1), but 
the actual number flown is a function of the other cargoes (dry, gas, 
propellant) that are also scheduled for that flight.

Instructions were uplinked for closing out the RED (resistive exercise
device) canister inspection, during which the crew discovered that the
failed canister has a damaged Flexpack. Resupply options as well as
salvage/refurbishment plans are currently being considered.

Today's targets for the CEO (crew earth observations program) were 
Angolan Biomass Burning (although this is not burning season in this 
part of the world, crew was advised to use this good pass in fair 
weather to look for burn scars from last season, primarily to the 
right of track), High Central Andean Glaciers (cloud cover was 
expected to be below normal over this target. As ISS crossed the crest 
of the Andes, crew was to try for context views of the snow and ice 
patterns either side of track), Eastern Mediterranean Dust (a series 
of winter storms continues to raise dust over Egypt and the eastern 
Med. Looking left or right of track this pass), Tigris-Euphrates, 
Turkey (crew was to use this break in the weather to shoot context 
views of the Tigris-Euphrates valley looking right of track, 
southeastward towards Syria and Iraq), Eastern Mediterranean Smog (as 
the crew tracked across southern Italy, they were to look obliquely 
left of track to document smog patterns over the mainland, the 
Adriatic Sea and the Balkan Peninsula), and Great Lake Ice (DYNAMIC 
EVENT TARGET: The time of maximum ice coverage of the Great Lakes is 
normally in February. As the crew tracked over northern Wisconsin, 
they were to document the ice extent of Lake Superior, left of track, 
and Lake Michigan, right).
