CSM Block I Chronology


1962 August 2 - .
  • Heatshield for Apollo boilerplate 1 completed - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. Summary: The heatshield for Apollo command module boilerplate model 1 was completed five days ahead of schedule..

1962 September 7 - .
  • Apollo boilerplate model BP-1 accepted by NASA - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. Apollo command module boilerplate model BP-1 was accepted by NASA and delivered to the NAA Engineering Development Laboratory for land and water impact tests. On September 25, BP-1 was drop-tested with good results. Earth-impact attenuation and crew shock absorption data were obtained.

1964 April 28-30 - .
  • Mockup inspection and review for Block II Apollo CSM - . Nation: USA. Related Persons: Johnson, Caldwell; Slayton. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. At Downey, Calif., MSC and North American officials conducted a mockup review on the Block I CSM. Major items reviewed were:

    • Cabin interior (complete except for hatches, display panel lighting, survival equipment, umbilical connections, and zero-g restraints).
    • CM exterior (complete except for hatches and boost protective cover).
    • Earth landing system.
    • Launch escape system.
    • SM.
    One hundred and eleven request for change forms were submitted to the mockup review board, composed of Robert O. Piland (Chairman), Christopher C. Kraft, Jr., Donald K. Slayton, Caldwell C. Johnson, Owen E. Maynard, and Clinton L. Taylor of MSC; and H. G. Osbon and Charles H. Feltz of North American.

    For the first time, three representative Apollo space suits were used in the CM couches. Pressurized suit demonstrations, with three suited astronauts lying side by side in the couches, showed that the prototype suit shoulders and elbows overlapped and prevented effective operation of the CM displays and controls. Previous tests, using only one suited subject, had indicated that suit mobility was adequate. Gemini suits, tested under the same conditions, proved much more usable. Moreover, using Gemini suits for Apollo earth orbital missions promised a substantial financial saving. As a result of further tests conducted in May, the decision was made to use the Gemini suits for these missions. The existing Apollo space suit contract effort was redirected to concentrate on later Apollo flights. A redesign of the Apollo suit shoulders and elbows also was begun.


1964 June 11 - .
  • Mandatory changes to Apollo Block I and Block II spacecraft - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I; CSM Block II. Summary: NASA directed North American Aviation, Inc. (NAA), to make certain mandatory changes to both Block I and Block II spacecraft systems..

1964 October 8-15 - .
  • Apollo CM instrument changes recommended - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. On the basis of reentry simulations, North American recommended several CM instrument changes. An additional reaction control system display was needed, the company reported. Further, the flight attitude and the stabilization and control system indicators must be modified to warn of a system failure before it became catastrophic. The entry monitor system for Block I spacecraft would have to be replaced and the sample g-meter was not wholly satisfactory.

1964 October 8-15 - .
  • Block I Apollo CM's heat rejection capability inadequate - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. Summary: Analysis by MSC of the performance of the environmental control system radiators for Block I CM's placed their heat rejection capability at 4,000 Btus per hr, far below the anticipated mission load of 7,220.. Additional Details: here....

1964 October 8-15 - .
  • Configuration established of the reaction control system engines - . Nation: USA. Program: Apollo. Spacecraft: Apollo LM; CSM Block I; LM RCS. MSC established the configuration of the reaction control system engines for both the service module (SM) and the LEM, and informed North American and Grumman accordingly. The Center also directed North American to propose a design for an electric heater that would provide thermal control in lunar orbit and during contingency operations. The design would be evaluated for use in Block I spacecraft as well.

1964 November 26-December 3 - .
  • Radiator for the environmental control system in Apollo Block I inadequate - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. Crew Systems Division (CSD) engineers evaluated the radiator for the environmental control system in Block I CSM's. The division was certain that, because of that item's inadequacy, Block I missions would have to be shortened.

    During the same period, however, the Systems Engineering Division (SED) reported "progress" in solving the radiator problem. SED stated that some "disagreement" existed on the radiator's capability. North American predicted a five-day capability; CSD placed the mission's limit at about two days. SED ordered further testing on the equipment to reconcile this difference.


1964 December 18 - .
  • North American delivered Apollo CM 001 - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. Summary: North American delivered spacecraft 001's CM to White Sands.

1965 January 14 - .
  • Apollo CM/SM umbilical cutter caused damage to the heatshield - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. During testing, it was found that blast effects of the linear charge for the CM/SM umbilical cutter caused considerable damage to the heatshield. To circumvent this problem, North American designed a vastly improved pyrotechnic-driven, guillotine-type cutter. MSC readily approved the new' device for both Block I and II spacecraft.

1965 February 4-11 - .
  • Real-time commands added to the up-data link equipment on Apollo command modules 012 and 014 - . Nation: USA. Program: Apollo. Flight: Apollo 204. Spacecraft: Apollo CSM; CSM Block I.

The two subjects' average donning times were nine min 33 sec and 10 min; mean doffing times were four min five sec and five min 23 sec.

1965 March 3 - .
  • Apollo Block I environmental control increased coolant - . Nation: USA. Program: Apollo. Flight: Apollo 204. Spacecraft: Apollo CSM; CSM Block I. To prevent radiator freezing - and consequent performance degradation - in the Block I environmental control system, MSC ordered North American to supplement the system's coolant. Forty-five kg (100 lbs) of water would be stored in the SMs of airframes 012 and 014.

1965 March 9 - .
  • Cracking of Apollo heatshield during cure - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. Avco found that cracking of the ablator during cure was caused by incomplete filling, leaving small voids in the material. The company ordered several changes in the manufacturing process: a different shape for the tip of the "filling gun" to facilitate filling those cells that were slightly distorted; manual rather than automatic retraction of the gun; and x-raying of the ablator prior to curing. Using these new methods, Avco repaired the aft heatshield and toroidal corner of airframe 006, which was then re-cured. No cracking was visible. The crew compartment heatshield for airframe 009 came through its cure equally well. Voids in the ablator had been reduced to about two percent. "It appears," Structures and Mechanics Division reported, "that the problem of cracking . . . has been solved by better manufacturing."

1965 March 11-18 - .
  • 27½ degrees Apollo CM hang angle during parachute descent retained - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I.

On June 25, the last five experiments were deleted and a cytogenic blood studies experiment was added.

1965 March 16-April 15 - .
  • Apollo high-angle water impact tests - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. North American dropped boilerplate 1 twice to measure the maximum pressures the CM would generate during a high-angle water impact. These figures agreed quite well with those obtained from similar tests with a one-tenth scale model of the spacecraft, and supported data from the model on side wall and tunnel pressures.

1965 March 24 - .
  • Apollo spacecraft AFRM 009 test paces the CSM program - . Nation: USA. Related Persons: Shea. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. Summary: ASPO Manager Joseph F.

1965 March 26 - .
  • Water impact tests with Apollo CM boilerplate - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. North American began a series of water impact tests with boilerplate 1 to obtain pressure data on the upper portions of the CM. Data on the side walls and tunnel agreed fairly well with those obtained from 1/10 scale model drops; this was not the case with pressures on the top deck, however.

1965 April 2 - .
  • Electrical power system for Apollo spacecraft 011 - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. North American presented final results of their modification to the electrical power system for spacecraft 011 to solve the power and energy problem. This consisted of the addition of three batteries which would be mounted on the center platform and used to supply instrumentation and mission control programmer loads during flight. These batteries would be paralleled with the entry and landing batteries at impact to provide power for postlanding recovery loads. MSC concurred with this approach.

1965 April 5-16 - .
  • Evaluation by simulator of the Apollo Block 11 CSM's manual thrust vector control - . Nation: USA. Program: Apollo. Spacecraft: Apollo CSM; CSM Block I. To evaluate the Block 11 CSM's manual thrust vector control, five pilots, among them two astronauts, flew the Apollo simulator at Honeywell. These mock flights demonstrated that the manual control was sufficiently accurate for transearth injection. Also, researchers determined that the optical alignment sight provided the crewmen with attitude references adequate for midcourse maneuvers.
