January 4

[103] John H. Disher, Deputy Director of Saturn Apollo Applications, established specific design criteria for the OWS mission. These criteria required MSFC to proceed with the design of the MDA and the integration of experiments into it for launch stowage. It also required MSFC to perform systems engineering analyses on the OWS ensuring its compatibility with the baseline configuration of the MDA. MSC was required to take action necessary for integration of government-furnished solar cells into the MDA and to examine the rechargeable battery capacity required for independent operation from the CSM.

Letter, John H. Disher to R. F. Thompson, MSC, and L. F. Belew, MSFC, "Orbital Workshop Configuration for 1968-1969 AAP Missions," 4 January 1967.


January 10

A Science and Applications Directorate was established at MSC to plan and implement MSC programs in space science and applications, act as the MSC focal point in these programs, and provide the Center's point of contact with the scientific community. Establishment of the Science and Application Directorate reflected the growing significance and responsibilities of MSC in these areas. The position of Director for the new organization was not filled at this time. Wilmot N. Hess was later named Director; Robert 0. Piland, Deputy Director.

MSC Announcement 67-7, 10 January 1967; MSC Announcement 67-27, 17 February 1967.


January 16

MSC requested assistance from LaRC through use of the Langley full-scale rendezvous docking simulator to provide data for AAP docking requirements. It was anticipated that the docking of the lunar mapping and survey system to the OWS would partially obstruct the pilots' view, and that the CSM payload configuration would have sluggish handling qualities in both translation and rotation. A study using the Langley full-scale rendezvous docking simulator would provide useful data for the AAP docking requirements.

January 26

At a NASA Hq briefing, Associate Administrator for Manned Space Flight George E. Mueller stated that NASA planned to form an "embryonic space station" in 1968-69 by clustering four AAP payloads launched at different times. The first mission would be the launch of a manned spacecraft followed several days later [104] by a spent S-IVB stage converted into an OWS. After the two spacecraft had docked, the crew would enter the Workshop through an airlock. Twenty-eight days later they would passivate the OWS and return to Earth in their spacecraft. In three to six months, a second manned spacecraft would be launched on a 56-day mission to deliver a resupply module to the OWS and to rendezvous with an unmanned ATM, the fourth and last launch of the series. The cluster would be joined together using the multiple docking adapter. Emphasizing the importance of manning the ATM, Mueller said that "if there is one thing the scientific community is agreed on it is that when you want to have a major telescope instrument in space it needs to be manned."

NASA Apollo Applications Briefing, 26 January 1967


January 27

Apollo Spacecraft Program Manager Joseph F. Shea sent a flash report to NASA Hq: "During a simulated countdown for mission AS-204 on January 27, 1967, an accident occurred in CM 012. This was a manned test with the prime astronaut crew onboard. A fire occurred inside the command module resulting in the death of the three astronauts [Virgil I. Grissom, Roger B. Chaffee, and Edward H. White, II] and as yet undetermined damage to the command and service modules." (See also 24 May 1967 entry.)

TWX, Joseph F. Shea to NASA Hq, Attn: Apollo Program Director, 28 January 1967.


February 1

Despite the fact that crew assignments for the ATM flight had not yet been made, Saturn/Apollo Applications Program Director Charles W. Mathews recommended to MSC AAP Manager Robert F. Thompson that scientist astronauts who had been participating in the ATM program at Huntsville be given an opportunity to visit a number of leading astronomical observatories in the country. In this manner, Mathews said, potential crew members could derive a better understanding of the equipment being employed, operation techniques being used, and the nature and types of observations being made.

February 2

The AAP experiments program was divided into two primary phases of activity- definition and development. During the definition phase, one of the major problems was the selection and definition of high-quality experiments from which a well-rounded experiments program could be identified in time to effectively support the planning of future missions and flight programs. Once the experiments were defined and approved for flight, the experiment passed into the development phase with somewhat different problems. During this second phase, such facets as program direction, resource requirements, program status, and problems encountered in experiment implementation were of primary concern.

February 23-25

A meeting at NASA Hq reviewed the status of mission configurations for the AAP-l/AAP-2, AAP- 3, and AAP-4. Agreement was reached on a baseline description for the first four flights.

Letter, Charles W. Mathews, NASA Hq, to Robert F Thompson, MSC, 9 March 1967.


February 28

A fundamental principle of AAP planning and implementation was the use of Apollo-developed components, subsystems, and operating procedures with no modifications wherever possible. By rigorous application of this principle, the cost of doing business in manned space exploration would be reduced, thus helping to ensure a continuing program leading to the next generation of manned space systems.

March 9

To facilitate program management operations involving inter-Center activities, Saturn/AAP Director Charles W. Mathews created an AAP Inter-Center Interface Panel structure. Panels included mechanical, electrical, instrumentation and communications, and mission evaluation. Two weeks later, Mathews added three more panels to the structure: mission requirements, systems integration, and systems safety.

March 15

[106] The Naval Research Laboratory awarded a subcontract to Ball Brothers Research Corporation for the production of the Apollo telescope mount NRL experiments. Prior subcontracts had been let with Ball for production of the High Altitude Observatory experiment on 11 January 1965, and for the Harvard College Observatory experiment on 27 December 1966. Development responsibility was transferred from Goddard Space Flight Center to MSFC.

NRL Contract N00014-67-C-0470, 1 June 1967.


March 17

Donald K. Slayton, MSC Director of Flight Crew Operations, expressed concern over the excessive number of experiments assigned to the first AAP mission. Experimenters had requested 672 man- hours for inflight accomplishment of experiments, where only 429 man-hours were available, creating a deficit of 243 inflight man-hours. The same problem was applicable to premission experiment training. Experimenters were requesting 485 hours per man for premission experiment training, where only 200 hours per man were available, creating a deficit of 285 hours per man.

Memorandum, Donald K. Slayton to Assistant Manager AAP, "Apollo Applications Mission 'A' experiments," 17 March 1967.


March 20

MSFC awarded Bendix Corporation a contract for development and production of the ATM pointing control system. The control system would enable astronauts to point a telescope at selected regions of the Sun during periods of maximum solar flare activity. MSFC had earlier awarded American Optical Company a contract to build a dynamic simulator for use in developing the pointing control system.

March 24

In response to AAP Assistant Manager Robert F. Thompson's request for technical support for AAP from existing Apollo contractors, Robert G. Chilton of the Guidance and Control Division recommended that the Massachusetts Institute of Technology Instrument Laboratory (MIT/IL), designer of the Apollo guidance and navigation system, be given the task of determining the suitability of the Apollo guidance and navigation system to perform the AAP missions. Since this task was of "prime importance at this stage of AAP planning," Chilton recommended that it have "immediate priority."

Memorandum, Robert G. Chilton, MSC, to Assistant Manager, AAP Office, "Apollo Applications Program (AAP) design analysis task for MIT/IL," 24 March 1967.


March 24

In accordance with design discussions and decisions reached during discussions several days earlier, AAP Director Charles W. Mathews directed Center AAP Managers to implement a modified OWS electrical power system. Because of increased electrical power requirements resulting from making the OWS a habitable [107] laboratory, solar cell arrays were added to each side of the S IVB stage to provide most of the electrical power used during AAP cluster operation. (Before this design shift, the CSM's fuel cells had been considered the primary source of power.) In addition, the ATM would still have its own solar array panels and power system.

April 3-12

Technicians from MSC's Landing and Recovery Division conducted demonstrations of land- landing at Ft. Hood, Texas, on 6, 11, and 12 April. The demonstrations were part of MSC's effort to develop an advanced system to provide a land-landing capability for the Apollo Applications Program, an improved launch abort situation, and reduced horizontal velocities for water landings.

Memorandum, C. C. Kraft, Jr., MSC, to Dist., "Advanced Landing System Operational Demonstration," 3 April 1967.


April 6

Donald K. Slayton, MSC Director of Flight Crew Operations, requested that the proposed T-020 "Jet Shoes" experiment be removed from all AAP flights. The "Jet Shoes" experiment was an astronaut maneuvering system consisting of two small thrusters mounted one beneath each foot and oriented so that the thrust vectors passed close to the center of body mass with legs and feet in a comfortable position.

During January, an engineering development model of the "Jet Shoes" was tested by several astronauts on the MSC air bearing facility in cooperation with the Principal Investigator. Although the tests by the astronauts were shirt-sleeve runs, [108] an LaRC test pilot made several runs in an inflated pressure suit. The results were unsatisfactory. In his objections to the experiment, Slayton suggested that its attempted use by an astronaut wearing a life support unit would provide extremely poor visibility.

Memorandum, Donald K. Slayton to Assistant Manager, MSC AAP, "Request for removing the T- 020 'Jet Shoes' Experiment from all AAP flights," 6 April 1967.


April 11

An AAP schedules meeting attended by the Center AAP Managers and the Headquarters' Directors was held on 31 March 1967 at NASA Hq. Consensus was that the airlock-multiple docking adapter tasks were well detailed and that the projected schedule for AAP-2 (Orbital Workshop operations) was realistic.

Memorandum, C. W. Mathews, NASA Hq, to M/Associate Administrator for Manned Space Flight, "Schedule Assessment of AAP 1-4," 11 April 1967


April 13

An informal presentation was made to NASA-KSC by Grumman Aircraft Engineering Corporation proposing Grumman as the integrating contractor for the hardware and facility modification phase at Launch Complex 37 (LC-37) for all phases of AAP activities on LC-37. The presentation defined the work and schedules confronting NASA at LC-37 for the AAP.

April 18-19

A meeting was held at MSFC to review the S-IVB stage for acceptability as a habitable vehicle. Personnel from MSC and MSFC attended. A presentation on the flammability testing of the liquid hydrogen tank insulation with an aluminum foil flame retardative liner was made by MSFC personnel. During the course of the meeting, various actions were established relating to habitability requirements of the S-IVB.

April 27

NASA awarded contracts to General Electric and Lockheed to conduct four-month parallel studies of a medical laboratory to support AAP missions. Designated the integrated medical and behavioral laboratory measurement system, the laboratory would permit detailed evaluation of body systems and crew functions during flight. It could be flown as a complete laboratory or as selected groups of measurement instruments on specific missions.

May 1

Both MSFC and MSC recognized the existence of a potential interference of contaminant materials in the vicinity of manned spacecraft with the optical equipment on the ATM. It was also recognized that certain building materials that might create contaminate problems needed to be avoided in the ATM structure. A considerable activity concerning this contamination problem had already developed at MSFC, MSC, NASA OSSA, some contractor plants, and the ATM Principal Investigators.

Letters, Wernher von Braun, MSFC, to Robert R. Gilruth, MSC, 8 March 1967; Robert R. Gilruth to Wernher von Braun, 1 May 1967.


May 2-10

A preliminary design review was conducted at MSFC during 2-10 May 1967 to evaluate the basic design approach of the MSFC/MSC/McDonnell Douglas team relative to the spent-stage aspects of the Orbital Workshop project. Purpose of the review was to define a baseline design on as many subsystems as possible and to define steps leading to a baseline on the remaining subsystems.

May 4

Confidence in any selected course of action in committing man to the space vehicle environment had grown slowly, based on actual experience. In this respect NASA had followed the philosophy of incremental exposure, generally doubling the duration of successive manned missions as long as no unforeseen medical problems were encountered in crews returning from space flight. This enabled NASA to acquire biomedical information from which to begin formulation of general statements about the effects of the space flight environment on human physiology.

May 5

Some significant features of a revised Apollo and AAP-integrated program plan were: CSM would be available to support the first four AAP launches; AAP-1/ AAP-2 in early 1969 were to accomplish OWS objectives; AAP-3/AAP-4 in mid-1969 were to accomplish the 56-day ATM objectives in conjunction with reuse of the OWS. Two additional AAP flights were planned for 1969 to revisit the OWS and the ATM using refurbished command modules flown initially on Earth-orbit Apollo flights in 1968. AAP missions planned for low Earth orbit during 1970 would utilize two dual launches (one manned CSM and one unmanned experiment module per dual launch) and two single-launch, long-duration CSM to establish and maintain near- continuous operation of the OWS cluster and a second ATM.

May 8

Required changes in the Apollo Applications Program flight schedules resulted in plans for the Earth-orbital test of the lunar mapping and scientific survey (LM&SS) as part of a single launch mission unrelated to the Orbital Workshop. The mission would have the primary objective of conducting manned experiments in space sciences and advanced technology and engineering, including the Earth-orbital simulation of LM&SS lunar operations. The LM&SS would be jettisoned after completing its Earth-orbital test. Planned launch date for the mission was 15 September 1968.

May 11

The AAP Office (NASA Hq) was preparing a draft task definition for a proposed command module modification contract. It would include primary and alternate locations for work; proposed interface of the modification contractor with North American; timing of the work effort; and definition of the work to be performed. Purpose of the proposed contract was to modify and refurbish Apollo hardware for AAP.

Release of a staff paper by J. Bollerud and C. Berry recommending a 35-kilonewtons-per-sq- m 69-percent-oxygen, 31-percent-nitrogen, shirt-sleeve atmosphere in the OWS initiated a discussion as to its impact on engineering design and operational plans, as well as the physiological response of test subjects to a one-gas (pure oxygen) system over extended periods of time. The consensus was that the 35-kilonewton (5 psia) oxygen-nitrogen for the OWS would best serve the needs of the OWS Earth-orbiting program.

May 15

[111] Guidelines and a set of minimum requirements to be met by each Center in establishing their configuration management systems for AAP were prescribed by NASA Hq. Configuration management systems would be progressively applied as individual projects matured. Once documentation such as a program or project baseline description had been officially issued, or documentation approved at formal design reviews such as a preliminary design review or critical design review, changes to such documentation would require formal approval through configuration management procedures, thereby establishing full configuration control at the critical design review.

W. Mathews to R. F. Thompson, L. F. Belew, and R. C. Hock, "Configuration Management," 15 May 1967.


May 23

Flight training hardware, identical in configuration to the flight hardware except that it need not be flight qualified, was required for training purposes. The training hardware consisted of those components of experiment hardware that required manipulation, handling, observation, or other usage by astronauts during flight. Neutral buoyancy training hardware was also required for underwater zero-g simulation training.

May 24

The ATM would offer a unique combination of several important advantages over previous manned orbital astronomical experiments, ground-based observatories, and unmanned orbital observatories. It would be the first U.S. manned mission with a primary goal of recovering scientific data. The ability to observe the Sun in previously inaccessible but important regions of the electromagnetic spectrum, to observe the details on the solar disk and in the corona for nearly two solar rotations, and to react rapidly to unpredictable and unexpected...

[112] ...occurrences with instruments of high data acquisition capabilities would be an unprecedented combination of opportunities available only to the crewman operating the ATM. However, it was essential to recognize that the crewman's ability to observe, exercise judgment, and efficiently conduct the routine experiment tasks, as well as to rapidly respond to unpredictable phenomena would be contingent upon the existence of displays in the proper wavelength regions with sufficient resolution to observe the important features on the solar disk. Also necessary would be controls which would combine simplicity and versatility to facilitate equipment setup for data acquisition.

May 24

Because of the Apollo 204 accident in January and the resulting program delays, NASA realigned its Apollo and AAP launch schedules. The new AAP schedule called for 25 Saturn IB and 14 Saturn V launches. Major hardware for these launches would be two Workshops flown on Saturn IB vehicles, two Saturn V Workshops, and three ATMs. Under this new schedule, the first Workshop launch would come in January 1969.

NASA Hq Schedule, 24 May 1967.


May 29

NASA announced that LaRC had selected Northrop Ventura Company to negotiate a contract to conduct a research program (including flight tests) of a flexible parawing for potential use in manned spacecraft landing systems. Northrop Ventura would evaluate the suitability of using a parawing (instead of conventional parachutes) to allow controlled descent in a shallow glide and thus offer wide flexibility in choosing a touchdown point, as well as provide a soft landing impact. The parawing would be evaluated for possible use on the Apollo Applications Program during the early 1970s to achieve a true land-landing mission capability.

May 31

A status review of the studies being conducted by North American Aviation on the AAP command and service modules' electrical power system was held at MSC. It was agreed that North American Aviation should pursue a two-regulator power control and regulation configuration and redundant battery changer configuration. The baseline fuel cell for AAP-1 would use 31- cell, ceria-coated, cobalt-activated fuel cells.

MSC, "AAPO Weekly Activity Report," 31 May 1967.


June 1

The Apollo Applications missions were designed to build upon the base of flight experience, ground facilities, and trained manpower developed in past programs.

[113] Each mission was designed to take full advantage of the Apollo Saturn system to make significant contributions to a wide range of objectives. Missions were planned to gain experience, test theory, perform experiments, and collect data.

Key elements of the planning included the decision to use, modify, and expand Apollo systems capabilities and to reuse basic hardware for multiple missions. Principal objectives of the AAP were the development of an extended flight capability to determine the usefulness of man in space; the conduct of manned astronomical observations from space; and the development of economical space flight through hardware reuse and long-duration flight.

June 1

During an informal discussion held in the Office of the Deputy Administrator, the AAP Office recommended that steps be taken to select a modification and refurbishment contractor to engage in a study of modification and refurbishment task requirements. The study would enable NASA to determine the feasibility of following a modification and refurbishment route for AAP.

June 5 -13

An Apollo Applications Program test review group, consisting of personnel from MSC, MSFC, and McDonnell, met in St. Louis on 5 June. The purpose of the meeting was a further definition of the ground rules governing the proposed integrated structural testing of the MDA/AM and to review the test requirements for compatibility. A second meeting of the group was held 13 June to review MSC, MSFC, and McDonnell facilities schedules to select a test site.

MSC, "AAPO Weekly Activity Report," 14 June 1967.


June 6

Kurt H. Debus, KSC Director, expressed concern that a proposal, if adopted, for a separate command and service modules launch contractor for AAP would create a very difficult operational environment. Debus said it was difficult to see how KSC could have two separate contractor teams responsible for checking out substantially the same kind of stage hardware on the same test equipment, when the schedule would require simultaneous operations or at least intermittent sequential activity by both contractors in the same facilities. KSC was already coping with the challenge of integrating, within common facilities, the work of six Apollo contractors preparing separate stages with separately assigned checkout equipment. A most serious problem would be the interference with ongoing mainline Apollo operations created by the activity of a new contractor attempting to familiarize himself with facilities, equipment, and procedures in the same timeframe as the most critical Apollo missions.

Letter, Kurt H. Debus to George E. Mueller, NASA Hq, 6 June 1967.


June 6

[114] At an American Institute of Aeronautics and Astronautics meeting in Washington, Associate Administrator for Manned Space Flight George E. Mueller outlined a number of innovations in AAP to achieve reductions in the unit cost of future space missions: (1) reuse of command modules; (2) land landing, which would greatly facilitate such spacecraft reuse; (3) "double use" of the S-IVB as both a propulsive stage and an OWS once in orbit; (4) repeated use of the OWS during a series of missions; (5) flights of increasingly longer duration (approaching perhaps a year or more); and employment of existing Apollo flight hardware, physical facilities, management expertise, and industrial organizations once they became available. Thus, said Mueller, AAP would evaluate man's usefulness in space at a relatively low cost, and that measurement would be "obtained by doing useful things-astronomical observation, extended exploration of the moon and experiments with sensing equipment that can lead to benefits of enormous significance to all mankind."

Astronautics and Aeronautics, 1967, p. 178.


June 19

The purposes of the AAP 1/AAP-2 mission were (1) to conduct a low-altitude, low-inclination, Earth- orbital mission with a crew of three men, open ended to 28 days' duration, using a spent S-IVB stage as an OWS; (2) to provide for reactivation and reuse of the OWS during subsequent missions occurring up to 1 year later; (3) to conduct inflight experiments in the areas of science, applications, technology, engineering, and medicine; and (4) to qualify man, evaluate his support requirements, and determine human task performance capability on long-duration manned space flight missions.

Objectives of the mission were to (1) demonstrate rendezvous and hard docking of the command and service modules to the multiple docking adapter; (2) determine the feasibility of operating the OWS as a habitable space structure for an extended period; and (3) obtain data to evaluate space flight environmental effects on the crew of a mission duration of 28 days.

June 30

Prenegotiation fact-finding sessions with Grumman were completed at MSC. Agreement was reached on the statement of work for the final definition (phase C) of the LM for the first LM/ATM mission and continued definition study (phase B) for utilization of the LM. Grumman cost proposals were discussed from the manning aspect only. Dollar figure discussion was delayed pending verification of bid rates.

MSC, "AAPO Weekly Activity Report," 5 July 1967.


July 3

MSC established an Apollo Applications Program Mission Design Information Group within the Mission Planning and Analysis Division. Function of the new group was to establish mission planning information requirements, acquire the necessary information, and integrate and publish the information in support of mission planning milestones. Data categories included such items as configuration, propulsion, aerodynamics, sequences of events inherent in spacecraft design, consumables, electrical power, environmental control, communications, thrust vector control, guidance and navigation, and mass properties.

MSC Announcement 67-101, "Apollo Applications Program Mission Design Information Group," 3 July 1967.


July 5

MSFC and MSC personnel met at MSC to resolve action items from a Headquarters test meeting held on 30 March. The action items involved the LM/ATM thermal vacuum test program. General agreement was reached on test configuration, with MSC supporting the MSFC position that a thermal vacuum test was necessary on the ATM flight unit. MSC agreed to conduct a chamber contamination test with jointly agreed upon procedures.

[116] MSC, "AAPO Weekly Activity Report," 5 July 1967.


July 11

Increased activity and interest in the ATM project created the necessity for conducting ATM monthly project reviews in the Office of Manned Space Flight. MSFC provided the principal inputs on such aspects as schedules, funding, and technical performance. Material covered progress achieved during the month, current problems, and actions taken.

July 24

A fact-finding tour of NASA's major manned space flight facilities at the end of June by Deputy Administrator Robert C. Seamans, Jr., and top members of the Administrator's immediate staff produced a broad evaluation of the program roles and workloads of the various Centers in light of coming Apollo accomplishments and transition to other manned space flight programs. In regard to AAP, staff members recommended to Seamans that flight schedules be stretched out to reduce costs, and that the agency investigate the feasibility of including Earthsensing payloads aboard the basic Apollo AAP spacecraft. In part, study of Earth-sensing payloads should include definition of those payloads per se; launch vehicle requirements to achieve high-inclination Earth orbits; development status of the AAP cluster hardware for the Orbital Workshop; definition of biomedical technology; and experiment requirements at MSC.

NASA Administrator James E. Webb testified on the NASA FY 1968 authorization bill before the Senate Committee on Appropriations' Subcommittee on Independent Offices. Asked by Sen. Spessard Holland (D Fla.) to make a choice between a substantial cut in funding for the Apollo Applications Program and the Voyager program, Webb replied that both were vital to the U.S. space effort. "The Apollo Application is a small investment to expend on something you have already spent $15 billion to get and it seems to me that this is important.

"On the other hand, the United States, if it retires from the exploration of the planetary field, in my view-, . . . [will face] the most serious consequences because the Russians are going to be moving out there and our knowledge of the forces that exist in the Solar System can affect the Earth and can be used for many purposes to serve mankind or for military power ...." Criticized by Sen. Holland for refusing to make a choice, Webb said he did not want "to give aid and comfort to anyone to cut out a program. I think it is essential that we do them both."

August 23

The ATM required a closely controlled environment during manufacture, quality checkout, and flight checkout activities. To ensure the required control of cleanliness, temperature, and humidity, two buildings were required at MSFC-one for the manufacturing process, the other for quality checkout. An environmentally controlled area was also required at KSC for flight checkout of the ATM.

August 29

In a letter to Saturn Apollo Applications Director Charles W. Mathews, MSC's AAP Assistant Manager Robert F. Thompson presented Houston's philosophy regarding major AAP reprogramming. Two factors, Thompson said, underlay the necessity for planning alterations: (1) the likelihood of funding cutbacks during 1968 and 1969 and (2) a clearer picture of how much Apollo hardware AAP might inherit, as Apollo reprogramming matured after the 204 accident. Thompson then set forth MSC's recommendations for the next phase of AAP planning: a manned Earth-orbital mission during 1969; two manned flights of 28 and 56 days using the OWS during 1970; a manned AAP/ATM flight during 1971; long-duration (two months to one year) manned flights during late 1971 and 1972; and manned lunar missions (including surface operations) in the post-Apollo period. In defining the AAP missions, however, Thompson stressed that until the Apollo goal of landing on the Moon had been achieved, AAP must be looked on as an "alternate to" rather than an "addition to" the main thrust of Apollo. It must be clear throughout the NASA manned space flight establishment [120] that Apollo and AAP would not be overlapping programs and that AAP must not compete with or detract from the main Apollo design.

The NASA Directors of the Apollo and Apollo Applications Programs Samuel C. Phillips and Charles W. Mathews, in a letter to their MSC counterparts, George M. Low and Robert F. Thompson, said: "Within the scope of the AAP program, it is desirable that an in-depth evaluation of a recovered CM be made as early as possible to fully determine the technical feasibility and economy of refurbishment and reuse of recovered Apollo Command Modules . "

They added that as a prerequisite to test and evaluation for refurbishment potential, salt water corrosive effects must be minimized on recovered spacecraft. This would involve some postflight operations to be performed aboard the recovery ship: dropping the aft heat shield, flushing the pressure shell, and drying and packaging for subsequent test and evaluation.

Low and Thompson were requested to coordinate and jointly establish postflight handling and test requirements for spacecraft 020 in a manner ensuring no impact on the Apollo 6 schedule or the postflight evaluation of the recovered spacecraft.

As originally conceived, the AM consisted of a simple tunnel and truss structure that provided access to the S-IVB OWS from the CSM. The AM subsystems provided distribution of power from the CSM to the OWS, a temperature regulated, clean atmosphere for the Workshop, and limited instrumentation.

After a year of program evolution, the AM, although similar in appearance and utilizing more than 60 percent of the effort expended on the original AM, had become physically different, with a considerably more complex role to play. The AM had become the hub and central "engine room" of the cluster by incorporating the electric power conditioning, storage, and distribution system. It was designed to receive and store power from the solar arrays, the CSM, and LM and to make distribution of power to the OWS, AM, MDA, CSM, and, in emergencies, the LM. The AM was designed to provide the central environmental control system for distributing a dehumidified, cleansed, odor free, temperature...

Saturn V OWS study teams were examining a range of concepts in two distinct categories, OWS B and OWS C. OWS B would be a relatively simple, generic evolution from the Saturn I OWS being developed for the first AAP missions. It would retain the basic elements of the Saturn I OWS but would incorporate the ATM solar astronomy payload as an integral part of the OWS. Other modifications to improve overall effectiveness would be incorporated where this could be achieved with small increments of funds or time. OWS C would be a more advanced concept in the evolution toward a flexible operational system for sustained operations in Earth orbit. It would provide living and working quarters for a crew of nine and would be operable for two or more years.

AAP was first presented as a separate Research and Development program in NASA's FY 1968 budget request, which was submitted to Congress in January 1967. As originally conceived, AAP was designed to take full advantage of the Nation's investment in Apollo-developed hardware, facilities, and manpower. However, in making adjustments to considerably lower funding, the program was pared down to the minimum level for maintaining a reasonable manned space flight program in the early part of the next decade and preserving any basic capability for future U.S. manned operations in space.

During the OWS preliminary design review, it was suggested that the AAP vehicles contain a library of material of an operational, technical, and recreational nature for use by the flight crews. Loewy and Snaith, Inc., had made a similar suggestion. A survey of AAP crew members was being conducted to determine the type and quantity of such materials the crews might desire so that design engineers could arrive at a preliminary systems approach to an inflight library and evaluate the impact.

March 28

MSC adopted the position that only mixed gas atmospheres should be considered for missions longer than 30 days in duration. Conceding that studies of the physiologic effects of mixed gas atmospheres, other than air, were new in number and controversial in nature, MSC suggested that such evidence as did exist indicated that nitrogen was a superior choice as a second atmospheric constituent from an overall medical standpoint.

April 3-15

Following discussions at the Manned Space Flight Management Council meeting at KSC on 21- 24 March, Associate Administrator for Manned Space Flight George E. Mueller and MSC Director Robert R. Gilruth concluded that, with the stringent funding restraints facing the AAP, the most practical near-term program was a Saturn IB OWS designed to simplify operational modes and [134] techniques in Earth orbit. It was agreed that a special task force would be set up to define and implement any changes necessary to the MDA, incorporate new experiments into the program, and plan and program the critical series of medical experiments required for AAP in order to collect vital data regarding crew performance during the early phases of AAP long-duration flights.

The MDA task force held an initial meeting at MSC on 10-11 April. Requirements for the critical medical experiments were identified, and potential Earth Applications experiments were reviewed. MSFC was requested to make a preliminary design analysis of the impact of incorporating critical medical experiments and to determine which Earth applications experiments could be accommodated.

In a speech before the National Space Club in Washington, AAP Director Charles W. Mathews stated that, beyond the goal of landing on the Moon, NASA's overall plan for manned space exploration comprised "a balanced activity of lunar exploration and extension of man's capabilities in Earth orbit." The AAP, Mathews declared, contained sufficient flexibility so that it could be conducted in harmony with available resources: "We are also prepared to move forward at an increased pace when it is desirable and possible to do so." He said contingency planning left room for both budgetary and mission goal changes, thus answering congressional criticism that NASA had not provided sufficient flexibility regarding long-term goals.

April 19

The OWS passivation sequence was described at a flight operations plan meeting held at MSC. Solar arrays would be deployed on the first stateside pass, since the liquid portion of the passivation would have been completed. Gaseous passivation was expected to require approximately 24 hours. The meteoroid bumper would not be deployed until crew arrival because it would interfere thermally with the passivation.

April 26

A briefing was held at Andrews Air Force Base, Maryland, on a recovery support study conducted by the Department of Defense Manager for Manned Space Flight Operations. NASA requirements provided for the study were based on two concepts of support. The "current concept" implied support requirements similar to those required for the Gemini program. The other was the "future [136] concept" which would be employed when sufficient reliability of spacecraft systems had been demonstrated. The "future concept" would employ two recovery zones (primary and secondary) as opposed to the four zones designated in the "current concept." Defense forces allocated to meet NASA requirements would be significantly reduced under the "future concept."

NASA, "AAP Weekly Progress and Problem Summary,' 26 April 1968.


April 30

A primary objective of the Apollo Applications reliability program would be to identify all significant single failure point potentials of equipment for various modes of operation. Single failure point potentials would be examined for each mission, and a summary of single failure points would be prepared and kept current. Supporting information from the Apollo program would be used to the maximum extent possible.

A LM/ATM Evaluation Board, established to make an in-depth review of the planned LM/ATM module configuration and mission, issued its final report. The Board review concentrated on the operational and programmatic aspects related to use of the LM with the ATM. At a meeting held on 9 March, the ATM experiment status was the subject of discussion. Principal Investigators and the MSFC ATM Program Office representatives summarized progress on each experiment and on the total ATM package.

At meetings held on 15 16 March, presentations were made by MSC and MSFC. MSC stressed the operational complexities of the dual-rendezvous, dualdocking capability of the LM, extravehicular activity, crew training, and mission critical sequencing. MSFC stressed the desirability of the cluster mission and, while recognizing the problems of dual rendezvous, suggested that the system and mission as configured was the best possible choice.

Final Report, LM/ATM Evaluation Board, 25 May 1968.


May 27

Center Directors Robert R. Gilruth (MSC) and Kurt H. Debus (KSC) approved a joint memorandum of understanding on MSC KSC relations that laid down guidelines and procedures for execution of Center responsibilities within areas of mutual interest. The document thus sought to ensure an effective programmatic interface between the two Centers and also provided for subsequent agreement, spelling out in detail specific inter-Center policies and procedures.

A review of the AM test program was held at MSC to examine the existing baseline AM testing plan in terms of programwide AAP test requirements and [138] guidelines. Participants included representatives from Headquarters, MSFC, MSC, and the AM contractor, McDonnell Douglas. Spokesmen for McDonnell Douglas recommended additional subsystem development testing, as well as thermal-vacuum testing of airlock flight hardware (a recommendation being evaluated by experts at both MSFC and MSC).

NASA, "Manned Space Flight Weekly Report," 3 June 1968.


June 4

NASA released a new AAP launch readiness and delivery schedule. The schedule decreased the number of Saturn flights to 11 Saturn IB flights and one Saturn V flight. It called for three Workshops. One of the Workshops would be launched by a Saturn IB, and another would serve as a backup. The third Workshop would be launched by a Saturn V. The schedule also included one ATM. Launch of the first Workshop would be in November 1970. Lunar missions were no longer planned in the AAP.

June 8

NASA launched two Aerobee 150 sounding rockets from White Sands Missile Range, New Mexico. The first rocket carried a Naval Research Laboratory and University of Maryland payload to a 179-km altitude to flight test a design verification unit of the high-resolution spectroheliograph planned for use on the ATM. The second rocket carried an American Science and Engineering, Inc., payload to a 150-km altitude to obtain high-resolution x-ray pictures of active regions of the Sun during solar flare and general x-ray emission of solar corona. The rocket and instrumentation performed satisfactorily, but the payload of the first rocket failed to separate, thus preventing functioning of the parachute recovery system.

July 23-24

At NASA Hq, movements were underway to select a new name for post-Apollo manned space flight (AAP)-one that would be more descriptive of the agency's real goals and objectives. At the Planning Study Group meeting, Douglas R. Lord, Chairman of the Working Group on Extension of Manned Space Flight, was asked to recommend a new name for NASA's Earth- orbital flight program of the mid-1970s. However, AAP Director Charles W. Mathews urged that the name AAP be retained because NASA had a good deal invested in it. On 26 July, Julian M. West wrote Lord recommending that NASA choose some other name to cover both AAP and an interim space base of the mid-1970s (dubbed the "IOWS" program, for Interim Orbital Workshop). West urged that all such names as "AAP," "Workshop," and "Extension of Manned Space Flight," be dropped because they did not accurately describe what he saw as "the major goal-manned space flight itself." West voted for a name put forward by George Trimble of MSC, "Space Base Program," which he believed covered NASA's mid-1970s missions. "We are establishing a foothold for man in space."

NASA, "Manned Space Flight Weekly Report," 16 August 1968.


August 9

ATM experiments would be designed to observe and record solar features or regions of interest by using a variety of scientific instruments and recording devices. Observations would be made over a wide range of energy wavelengths in the form of both solar images and solar spectra. They would be preserved for future study by recording them on photographic film or magnetic tape. These experiments would provide new knowledge of the Sun, solar features, solar phenomena, and the solar processes of energy release.

MSC, "ATM Mission Review," 9 August 1968.


August 12

MSFC issued a request for proposals to design and develop an actuator system for the ATM. The device, expected to weigh about 9 kg, would deploy the ATM's solar panels once the vehicle was placed in orbit and docked with the Workshop.

MSFC News Release 67 -178, 12 August 1968.

MSFC informed MSC that General Electric Company had been awarded a contract for "Human Engineering Criteria for Maintenance and Repair Study." The contract would yield data directly applicable to the AAP-2 and AAP-4 flights, as well as later missions. The underwater testing portion of the study required the use of space suits, and it was felt that the most useful data would be achieved if Apollo-type space suits could be used. MSC was requested to furnish two suits for that portion of the study to be performed at General Electric's Valley Forge, Pennsylvania, facility in October 1968.

September 17

Supporting development work in AAP was eliminated, except that of an urgent or critical nature, such as the integrated medical and behavioral laboratory measurement system. This reduction in program supporting development work was the result of budget restrictions when available appropriated funds were reduced from $32.0 million to $18.2 million for Apollo and AAP.

Letter, George E. Mueller, NASA Hq, to Robert R. Gilruth, MSC, 17 September 1 968.


September 23-26

An analysis was made of CSM modifications proposed for AAP. The AAP spacecraft requirements and the subsequent subsystem modifications from the Apollo spacecraft resulted from the longer mission duration, increased mission support, docked attitude constraints, and cost and weight factors involved in AAP.

MSC responded to a 4 October 1968 request from NASA Hq to further study selected SLA modifications and a short MDA docking tunnel. MSFC asked North American to study two cases involving SLA modifications. In both cases, North American utilized the probe cover configuration: (1) case I utilized a nose cone, rocket jettison motor, a modified Apollo SLA, and the Apollo SLA ordnance separation system; (2) case II utilized a lightweight segmented nose section designed as an integral portion of a modified Apollo SLA. This case also used the Apollo SLA ordnance separation system with a lateral jettison of the integral nose section/SLA enclosure.

[146] Review of this study indicated that in either case, although both could be considered technically feasible, additional analyses would be required including dynamic analysis (recontact), thermodynamic analysis, and modifications to ground support equipment. MSFC had reexamined the possibility of shortening the MDA docking tunnel, which would eliminate the need for a SLA modification. Two constraining factors governing the modification were (1) sufficient tunnel standoff distance from MDA pressure to assure no LM contact with the MDA and (2) launch clearance between the MDA Port I cover and the interior surface of the SLA.

It was felt that any compromises that would necessarily complicate the design and operation of orbiting spacecraft hardware (MDA) as opposed to modification of expendable (SLA) hardware would not be the best choice, and MSFC therefore recommended that the "short tunnel" not be pursued further.

MSC awarded a contract to Allis-Chalmers Manufacturing Company to flightqualify the improved fuel cell electrical power system for AAP. The fuel cell system had been developed under three previous contracts that began in 1962. Under the present contract (to run through February 1970), Allis-Chalmers would try to achieve fuel cell lifetimes of 2500 hours to ensure adequate margins to satisfy 1500-hour manned AAP missions. (See 18 July 1969 entry.)
