SL 4 planning issues.

The key points resulting from this discussion were:

(1) The normal mission launch would be scheduled to allow the first fifth orbit rendezvous opportunity occurring on or after 9 November 1973. Current estimates indicated an 11 November launch.

(2) The mission would be planned for a nominal 56- to 59-day duration. Splashdown date would be adjusted so that a return to port would be accomplished within 24 hours after recovery.

(3) There would be no primary recovery ship utilization planned for other than a normal end-of- mission recovery.

(4) KSC would continue the present rescue vehicle flow through 9 September 1973 (readiness for hypergolic loading), at which time a hold mode with a nine-day launch capability would be maintained. The decision to load hypergolics would be made by the Program Director.

(5) A review to examine the Workshop systems fully would be held on 17 September 1973, at which time the capability of the Workshop to perform the normal scheduled mission on the scheduled date would be established. For planning purposes, a minimum of 21 days' preparation would be allowed for an orderly launch acceleration if the review showed such a necessity.

(6) At SL 3 splashdown, the SL-4 KSC flow would revert to the normal mode. Retesting and additional tests would be performed as necessary.

(7) The SL-4 mission was not to be predicated on the availability of the S201 far ultraviolet camera. However, attempts would be made to accomplish its development.

(8) Onboard consumables would be reserved for comet observations. Film was to be budgeted to ensure that an ample quantity was available for the comet viewing period. Mission planning would assume no additional film or tapes beyond those currently baselined.

(9) Three EVAs would be baselined for conduct of scientific experiments. However, expendables to enable one unscheduled EVA for system contingencies would be provisioned. Mission planning would reserve those expendables.

(10) Comet observation would be given the highest priority over other experiment activities during the period from 16 December 1973 to the end of the mission.

(11) One maneuver per day would be baselined for comet observation, with a goal to conduct an added maneuver to meet established experiment objectives . Maneuvers would be constrained as outlined in the systems management criteria document.

(12) Funding for the experiment modifications would be the responsibility of the development center after 16 August 1973.
