The command module (CM) would now be required to provide the crew with a one-day habitable environment and a survival environment for one week after touching down on land or water. In case of a landing at sea, the CM should be able to recover from any attitude and float upright with egress hatches free of water. Additional Details: here....
The mission constraints to be used for this study were :
Four days earlier, MSC had added specifications for an extravehicular suit communications and telemetry (EVSCT) system to the space suit contract with Hamilton Standard Division of United Aircraft Corporation. The EVSCT system included equipment for three major operations:
Those attending the meeting foresaw a number of problems:
Also MSC advised Grumman that estimates of the metabolic rates for astronauts on the lunar surface had been increased. The major effect of this change was an increase in the requirements for oxygen and water for the portable life support system.
SED requested that a study be initiated to:
Charles A. Bassett - operations handbooks, training, and simulators
Alan L. Bean - recovery systems
Michael Collins - pressure suits and extravehicular activity
David R. Scott - mission planning and guidance and navigation
Clifton C. Williams - range operations, deep space instrumentation, and crew safety.
Donn F. Eisele - CSM and LEM
William A. Anders - environmental control system and radiation and thermal systems
Eugene A. Cernan - boosters, spacecraft propulsion, and the Agena stage
Roger B. Chaffee - communications, flight controls, and docking
R. Walter Cunningham - electrical and sequential systems and non-flight experiments
Russell L. Schweickart - in-flight experiments and future programs.
Since the baffled injector represented the final hardware configuration, it was highly desirable to use the design for these tests. MSC requested that availability of the injector constrain the tests and that Grumman take necessary action to ensure compliance.
The same rationale would be applicable to the LEM and Block II vehicle chamber tests. Only flight configured spacecraft hardware and extravehicular mobility unit garments would be used by test subjects.
As a result of this analysis, MSC directed Grumman to design the LEM ECS with an all-gaseous oxygen storage system.
Seeking some answer to this problem, CSD engineers began in-house studies of temperature changes in the spacecraft's oxygen. There was some optimism that Grumman's estimates would be proved much too high, and MSC thus far had made no changes either to the ECS or to the PLSS.
At an MSC meeting attended by ASPO, CSD, and Lunar Sample Receiving Laboratory representatives, it was decided that the following directions would be sent to Grumman:
He suggested that if an SPS failed the service module be jettisoned for a time-critical abort and both LEM propulsion systems be used for earth return, reducing the total time to return by approximately 60 hours. As an example, if the time of abort was 10 hours after translunar injection, he said, this method would require about 36 hours; if the SM were retained the return time would require about 96 hours.
He added that the LEM/CM-only configuration should be studied for any constraints that would preclude initiating this kind of time-critical abort. Some of the factors to be considered should be:
Flight Operations Director Christopher C. Kraft, Jr., conducted the discussion, with Rodney G. Rose, Carl Kovitz, Morris V. Jenkins, William E. Platt, James E. Hannigan, Bruce H. Walton, and William L. Davidson participating.
The major factors (philosophy) identified at the meeting were:
On October 26, the Director of Flight Crew Operations stated that his Directorate was formulating and implementing a training program for flight crews to give them experience in coping with fire in and around the spacecraft. "In total, the crew training for cockpit fires will consist of: Review of BP 1224 and M-6 'burn test' film; demonstration briefings on the fire extinguishers and their most effective use; procedural practice simulating cockpit fire situations in conjunction with one 'g' spacecraft/mockup/Apollo Mission Simulator walkthroughs and in the egress trainer placed in the altitude chamber; and as a part of the overall launch pad emergency and evacuation procedures training at the fire service training area at KSC."
