This proposal line_4: provides an opportunity to make whatever changes are line_5: necessary to transition the FOC to the SMOV Hold line_6: state. ! ! end of abstract general_form_proposers: lname: MIEBACH fname: MANFRED inst: STSCI country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: This proposal comprises two activities. The first line_2: activity will allow for the transition of the FOC to line_3: the SAFE-MODE recovery state. The second, which line_4: occurs after the safe mode recovery, allows for the line_5: transition to the SMOV specific HOLD mode if it is line_6: different from the standard HOLD. line_7: The commanding in each activity will be determined line_8: based on the state of the FOC after the Shuttle line_9: portion of the servicing mission. line_10: Presently the shuttle portion of the servicing mission line_11: brings the FOC to the state needed for SMOV. Thus at line_12: present the instructions associated with these activities line_13: will not generate any commanding. ! question: 5 section: 1 line_1: These activities must be the first FOC activities on line_2: the SMOV SMS's. The only prerequisite for this activity line_3: is the beginning of SMOV SMS execution and it is a line_4: prerequisite for all FOC SMOV activities. line_6: The implementation of this proposal will change depending on line_7: the response to the following questions: line_8: 1. Does the FOC need to be recovered from Safe-mode? line_9: 2. Has the FOC high voltage pressure constraint been met? line_10: If the answer to the first question is yes, the instruction for line_11: Line 1 must be changed to SXRECOVER1. line_12: If the answer to both lines is yes, the instruction for Line 2 line_13: must be changed to SXKNOWN." ! !end of general form text general_form_address: lname: MIEBACH fname: MANFRED category: PI inst: STScI addr_1: 3700 San Martin Drive city: Baltimore state: MD zip: 21218 country: USA phone: 410-338-4544 ! ! end of general_form_address records !
