cleaning equipment for the sinks and the head, instruments and equipment for 

 program tasks, soaps, the head, and storage areas for housekeeping equipment. 

 Numerous written comments were made by the aquanauts on the forms to clarify 

 the problems involved. For example, the head leaked, spit water back when 

 flushed, and was poorly ventilated; tools were not carefully matched to the 

 sizes and requi reman ts of what was in thehabitat; andworking areas were desi gned 

 so that too many activities occurred in them, making it difficult for several 

 aquanauts to do in-habitat research at the same time. Also, the areas for 

 private reflection (the cupola and the bunks) were considered too small and 

 were not private enough. 



On the other hand, the most popular elements of the habitat, rated close to very 

 good, included recorded music (there was a selection of about 20 audio cassettes 

 in the habitat, including classical, rock, western, folk, and other types of 

 music, the emphasis being on classical); the shower; the floor coverings (the 

 floor covering of the wet room, however, was not lilted as well as the carpet 

 used in the other rooms); and temperature regulation. 



Figure I illustrates the HARS ratings grouped into major clusters of like factors. 

 High numbers are good, and low numerical ratings are poorer. As shown, the 

 habitat generally was rated "above par" in terms of this particular scale. 



The composite results of the TEA are listed in Table I. Each of the 138 TEA 

 cells, as well as its 12 rows and 13 columns are shown. Of the 12 rows describ- 

 ing different types of environmental support in the habitat, temperature and 

 humidity score quite high; this agrees with the high rating on the HARS of the 

 air-conditioning or environmental control system. The two most significant 

 problem areas are (I) lack of noise control in the habitat and (2) lack of 

 variety. From this measure it is clear that the most unfavorably rated func- 

 tional areas are those reserved for in-habitat science. The lowest rating char- 

 acteristics of all the areas are acoustics and variety. 



This measure correlates well with the HARS measure; both emphasize the importance 

 of adequate work facilities. 



Aquanaut Moods 



What emerged in our findings about the moods of the aquanauts was somewhat 

 surprising. As shown in Table II, it appears that aquanauts felt very little 

 anxiety during their stay in the habitat and very little depression as well. 

 Positive moods, i ncl ud ing concentration, activation, social affection, pleasant- 

 ness, and nonchalance, strongly predominate.^^ 



"■■ This predominance of positive affect is much less apparent as mission 

 duration increases. Data pertinent to this problem are presented 

 subsequently.
