2\18 ISS On-Orbit Status 18-02-2002
Part 2 of 2

Early in the morning, at 2:59am EST, amateur radio operator Don Pettit
chatted with students of Hirano Elementary School in Kobe, Japan, 
during a 10-min. ham radio pass. [Hirano Elementary School, opened in 
1876, is a small school with only 180 students now, located in the 
western part of Kobe-city.]

The crew participated in a PAO TV interview with the Russian HTB TV 
program "Morning Channel", via SM video and audio downlink to TsUP 
(subject: ISS assembly plans).

Late in the day, Budarin set up the equipment for tomorrow's planned 
Russian biochemical urine test (PZE MO-9), which uses the 
sophisticated in-vitro diagnostic "Urolux" apparatus developed years 
ago for the Mir program. [MO-9 is one of several Russian medical 
assessments that have been accepted by US MedOps officials in the 
interest of working more jointly as an Integrated Medical Group (IMG). 
It is performed every 30 days, also before and after Orlan EVAs.]

Today's targets for the CEO (crew earth observations) program were 
Lake Chad in Sun Glint (after nearly disappearing completely during 
the Sahelian drought of the 1980's, this once-large lake has been 
making a slow recovery during the past decade. Crew was to take 
advantage of this sunglint-enhanced view well to right of track to 
help detect and map water between sand dunes on the lakebed), Dakar, 
Senegal (the city of Dakar may not have been visible this pass, but 
oblique views to the left of track should have picked up dust moving 
westward out to sea. Crew was asked to try to include landmarks in 
your views, if possible), Eastern Mediterranean Dust (with a winter 
storm tracking eastward from the western Med, dust from Libya is 
expected to move northward toward Italy. Looking left of track to 
document this event), and Newfoundland Ice Floes (a major winter storm 
is approaching from the SW, but crew was to try looking right of track 
this pass to capture the massive, swirling ice floe pattern off of 
Newfoundland's jagged eastern coastline).
