2\14 ISS On-Orbit Status 14-02-2003
Part 2 of 2

MSG (Microgravity Science Glovebox) Update: Progress by ESA/Astrium in
developing safe troubleshooting procedures is slower than anticipated. 
They now appear to become available "very late next week" (~2/21). 
Actual on-board troubleshooting of the MSG rack would then take place 
during the week of 2/24.

The crew conducted a Russian TV press interview at ~8:00am EST with 
the VESTI (News) Program in Moscow.

Today's targets for the CEO (crew earth observations program) were
Congo-Zimbabwe Biomass Burning (with especially fair weather over 
Zimbabwe this pass, looking right of track for burn scars from 
previous fire seasons and the coincident land use patterns), Lake 
Nasser, Toshka Lakes; Egypt (scientists are continuing to monitor the 
Lake Nasser region for indications of change in the flow of the Nile 
River or changes in lake levels, especially the new lakes to the 
west), Subtropical Jet Stream (the subtropical jet stream is active 
over western Africa and persists, producing dramatic cloud formations. 
As ISS tracked northeastward off the coast, crew was to look obliquely 
inland to the right of track to document details of the cloud 
structures), Eastern Mediterranean Smog (high pressure has held over 
the central Med for days now allowing the buildup of aerosols in the 
region. On this pass, the crew was to look right of track down the 
length of the Adriatic Seas for smog plumes over the water and 
adjacent land areas), Everglades in Sun Glint (crew was to take 
advantage of special lighting conditions to capture much of far south 
Florida in sun glint as it enhances the detection of water bodies and 
control structures), and Gulf of St Lawrence Sea Ice (it has been a 
cold, hard winter over eastern North America. The crew was to use this 
break in the weather to document the extent of sea ice over this 
important seaway).
