Reply to a paper on the use of two magnetometers for magnetic field measurements on a spacecraft
The use of two magnetometers for measuring the ambient magnetic field of spacecraft is compared with the single magnetometer variance method. It is shown that the dual magnetometer concept was developed for missions which are conducted with attitude stabilized spacecraft which have been constructed without an adequate magnetics control program. Specific methods for applying the dual magnetometer technique are described and an error analysis is conducted to determine the accuracy of the results.

Symposium on Uranium Plasmas: Research and Applications, 2nd, Atlanta, Ga., November 15-17, 1971, Collection of Technical Papers.
Results of theoretical and applied research related to fissioning uranium plasmas. Topics examined include uranium plasma instabilities, diagnostic techniques, radiant heat transfer characteristics, nuclear pumping of lasers, and various fission engine concepts. Engineering aspects considered for open-cycle gas core engines include effects of buoyancy on fuel containment, flow and criticality problems, effects of injection conditions, and radiation hazards. The nuclear light bulb engine, the mini-cavity reactor, the dust-bed reactor, and the colloid core reactor are also examined in terms of design and control considerations. Individual items are abstracted in this issue.

Discussion of paper by A. E. Ringwood, Petrogenesis of Apollo 11 basalts and implications for lunar origin.
Critical review of statements put forward by Ringwood about the origin of the moon. The composition of the lunar basalts is discussed, and it is shown that many theories for the origin of the moon can explain this composition satisfactorily. It is pointed out that the closeness of the relationship between Martian basalts and earth basalts is a matter of opinion, and that the major geochemical features that must be explained are certainly the low iron content in the moon and the depletion of volatiles. The manner in which various hypotheses of lunar origin deal with this explanation is examined.
