S/C: - GOT: The problem with hang-up of scripts, such as happened during last week's LETG insertion and retraction, is being worked by Lockheed-Huntsville. They have been testing the script and think they have found a problem related to the latest release of the ONLS. They are planning to send a patch shortly, to be tested at OCC 3rd string, and then presented to the FDB for approval. Roger instructed that regression testing in the future should include checking such script operations. SOT: Radiation is low. ASCDS: several QLs. The Grinch disabled our color printers. OCC Mgr: Trip to JPL DSN Friday, presented our results that we have more problems on the 26m antennae than on the 34m ones. These problems are not correlated with altitude. We proposed that in 2003 for the 4 month period we just decrease the use of 34m, not eliminate it entirely. This was received positively by JPL.
