Dr. NEWELL. Thank you, Mr. Chairman.

Mr. KARTH. Dr. Newell, I want to thank you very much for your

statement.

I might suggest that at this time we recess until 2 o'clock this afternoon since it is now about 12 minutes of noon and the House goes into session. We would like to get permission so that we can sit during the regular order of business of the House this afternoon.

If there are no objections, we will now recess until 2 o'clock this afternoon, at which time Mr. Nicks will be with us.

(Whereupon, at 11:48 a.m., the subcommittee was recessed to reconvene at 2 p.m. the same day.)

AFTERNOON SESSION

Mr. KARTH. The meeting will come to order.

This afternoon we are privileged to have with us the Director of the Interplanetary Programs of the Office of Space Science and Applications, Mr. Oran Nicks.

Mr. Nicks had suggested that he could summarize his statement in about 20 minutes. I felt that, because there may be materials in the prepared statement that the subcommittee would otherwise not be familiar with, he proceed with the prepared statement. Unless there is objection, we will proceed in that fashion.

Mr. Nicks, welcome to the subcommittee, and thank you very much for taking time out from your busy schedule to be here. You may proceed, if you will.

STATEMENT OF ORAN W. NICKS, DIRECTOR, LUNAR AND PLANETARY PROGRAMS, OFFICE OF SPACE SCIENCE AND APPLICATIONS, ACCOMPANIED BY N. W. CUNNINGHAM, RANGER PROGRAM MANAGER, NASA, AND H. M. SCHURMEIER, RANGER PROJECT MANAGER, JPL

Mr. NICKS. Thank you very much, Mr. Chairman.

Before proceeding, I would like to introduce Mr. N. W. Cunningham on my right. His name is Newton, but we call him Bill, program manager for Ranger, and Mr. H. M. Schurmeier on my left, whom we call Bud. Bud is the Ranger project manager at JPL on the Ranger. Before reviewing the Ranger program in detail, I should like to summarize some major points which are pertinent to the present investigation.

The Ranger concept of employing a basic spacecraft to carry different payloads was chosen because of a desire to amortize development experience and costs on all elements except the scientific payload, which must be tailored to the specific investigations desired at a given time. I believe the Ranger program has demonstrated the soundness of that concept. The Ranger VI carried the third type of scientific. payload to be adapted to the Ranger, the spacecraft bus retained basic elements and the original concept throughout, and it performed its functions as intended.

It is also believed that the concept of multiple flights, divided into blocks aimed at accomplishing specified objectives, has been validated. The block concept was initiated because it was recognized that existing statistics on vehicle performance indicated the probability of 50 to 75 percent launch successes.

Although the realization of these facts was the basis of the planning process, it should be emphasized that we have tried to regard each spacecraft as if it were the only one we had, and have endeavored to achieve 100 percent success on each flight. Never has the "Ordnance

51

philosophy" of accepting a certain percentage of success been adopted. Mr. KARTH. I assume there is considerable disagreement with that statement.

Mr. NICKS. The Ordnance concept?

Mr. KARTH. If that is the Ordnance philosophy.

Mr. NICKS. Well, sir, I meant by that the philosophy of knowing that in a certain number of rounds there could be some percentage of defective rounds which when recognized calls for an increased number of shots to overcome that deficit. I didn't mean it in a derogatory sense at all. I think it is a very common method of providing

Mr. KARTH. I didn't mean to argue with that. My point was that I had heard considerable comment about the philosophy that had been adopted for the Ranger program, at least the initial four or five. The time schedule, for example, was more important than reliability, and from that standpoint I would say that perhaps it did fit into the Ordnance philosophy.

Mr. NICKS. I think, sir, that our approval might have been challenged because we did have three firings the first year of the Ranger program. However, as you heard this morning, the first two of those spacecraft seemed to work satisfactorily. We knew what was wrong with the launch vehicle and were able to fix it, so we didn't have reason to hold up the regular schedule which had been set. After Ranger IV and Ranger V, we have had these long periods of waiting to try and fix what we thought was wrong. Although it may be that the later failures made it look as if we were firing without fixing things. There didn't seem to be anything to fix after the first two that there was not time enough to fix within the original schedule.

Mr. KARTH. I see. I am glad you made that explanation, because I have been aware of some criticisms which have been made. I think they have been official or semiofficial criticisms that the philosophy adopted generally was "shoot and hope it works" as opposed to extensive and reliable testing procedures prior to the launching of the craft.

Mr. NICKS. I hope we can give you a different viewpoint after this hearing today.

Although Mr. Cortright has covered this point, I should like to reiterate for the record that only four Rangers have been launched toward the Moon, and that two of these succeeded in hitting this difficult target. Because our goals were justifiably higher, the impacts alone were not satisfying. However, the evolutionary development of the launch vehicle system, the spacecraft, the operations techniques, and the deep space net work has been marked.

The initiation of this major effort 5 years ago was accompanied with many tasks of organizing diffuse elements across the country into a project team. At the present time, my staff and I are in daily contact with project management personnel. I would like to make it clear that we have been and are participating in all major program decisions in accordance with established NASA policies for the management of such projects, and that we know what is going on within the project. Mr. KARTH. Could you tell us, Mr. Nicks, approximately when this policy was adopted?
