Deep Impact I&T Report, Monday, January 28 and Tuesday, January 29, 2003  CML 
                                                                              
Monday was a day of slow progress. Some difficulties were                     
found in the instrument testing, on both the flyby and Impactor sides.        
                                                                              
The Impactor camera test setup is having power supply problems and a          
cooling valve froze yesterday; both are minor issues which are expected       
to be fixed today. Images of the interior of the Ball 8 chamber from          
the ITS camera CCD have already been taken, so we have a live imaging         
system. This morning, Tuesday, a series of warm functional tests will be run. 
Cold (-20 to -30 C) calibration data should begin to be taken by              
early afternoon on Wednesday.                                                 
                                                                              
The vibration test of the Flyby instrument platform showed some worrisome     
changes from the instrument tests, suggesting that there may be a loose       
fitting between the camera assemblies and the instrument platform that        
needs to be found. We just had a meeting to figure out how to do this in      
the lowest risk, fastest possible way. So today they will do a quick check    
of the alignment of the instruments on the vibration table, then do a small   
shake to see if the problem is still there, and if it is, take the assembly   
back to the clean room and look at the loose connections which most likely    
 are causing the decrease in vibration amplitude seen. We should have more    
on the issue by mid-afternoon.
