Apollo 11 Objectives

 

 

Spacecraft Primary Objective

 

1.      To perform a manned lunar landing and return. Achieved.

 

Spacecraft Secondary Objectives

 

1.     To perform selenological inspection and sampling.

 

A.     Contingency sample collection. Achieved.

 

E.      Lunar surface characteristics. Achieved.

 

F.      Bulk sample collection. Achieved.

 

H.     Lunar environment visibility. Achieved.

 

2.     To obtain data to assess the capability and limitations of the astronaut and his equipment in the lunar surface environment.

 

B.     Lunar surface extravehicular operations. Achieved.

 

C.     Lunar surface operations with extravehicular mobility unit. Achieved.

 

D.     Landing effects on lunar module. Achieved.

 

G.     Location of landed lunar module. Partially achieved. The LM crew was unable to make observations of lunar features during descent. The command module pilot was therefore unable to locate the lunar module through the sextant. Toward the end of the lunar surface stay, the location of the lunar module was determined from the lunar module rendezvous radar tracking data, which was confirmed post‑mission using descent photographic data.

 

I.     Assessment of contamination by lunar material. Achieved.

 

L.      Television coverage. Achieved.

 

M.   Photographic coverage. Achieved.

 

1)      Long distance coverage from the command module.

 

2)      Lunar mapping photography from orbit.

 

3)      Landed lunar module location.

 

4)      Sequence photography during descent, lunar stay, and ascent.

 

5)      Still photographs through the lunar module window.

 

6)      Still photographs on the lunar surface.

 

7)      Close‑up stereo photography.

 

Experiments

 

1.      S-031: Passive seismic experiment. Achieved.

 

2.      S-059: Lunar field geology. Partially achieved. Although two core tube samples and 15 pounds of additional lunar samples were obtained, time constraints precluded collection of these samples with the degree of documentation originally planned. In addition, time did not permit the collection of a lunar environmental sample or a gas analysis sample in the two special containers provided. It was, however, possible to obtain the desired results using other samples contained in the regular sample return containers.

 

3.      S-078: Laser ranging retroreflector experiment. Achieved.

 

4.      S-080: Solar wind composition. Achieved.

 

5.      S-151: Cosmic ray detection. Achieved.

 

6.      M-151: Pilot describing function. Achieved.

 

 

Launch Vehicle Objectives

 

1.      To launch on a variable 72 to 108 flight azimuth and insert the S‑IVB, instrument unit, spacecraft into a circular Earth parking orbit. Achieved.

 

2.      To restart the S‑IVB during either the second or third revolution, and injection of the S‑IVB, instrument unit, spacecraft into the planned translunar trajectory. Achieved.

 

3.      To provide the required attitude control for the S‑IVB, instrument unit, spacecraft during the transposition, docking, and ejection maneuver. Achieved.

 

4.      To use residual S‑IVB propellants and auxiliary propulsion system after final launch vehicle/spacecraft separation, to safe the S‑IVB, and to minimize the possibility of the following, in order of priority:

 

a.       S‑IVB/instrument unit recontact with the spacecraft. Achieved.

 

b.      S‑IVB/instrument unit Earth impact. Achieved.

 

c.       S‑IVB/instrument unit lunar impact. Achieved.
