Psychology of Space Exploration At that time, lack of diversity at NASA was not limited to the astronaut corps. In 1974, Congress held a hearing on NASA’s Equal Employment Opportunity Program. The chairman’s introductory remarks included the statement “It is clear that the NASA equal employment opportunity effort over the years has been inad - equate . . . .” 75 In the congressional report, NASA admitted that as of the end of scal year (FY) 1971, of all NASA employees, only 16.6 percent were women and 4.6 percent minorities. 76 Only 3 percent of the supervisors and 2.4 percent of the engineers were women. Kim McQuaid points out that many forces worked against increasing the pro - portion of women and blacks at NASA. 77 Nationally, efforts to increase diversity through new employment strategies began at about the same time as NASA our - ished in the late 1960s and early 1970s. Special hurdles at NASA included an organizational culture that was built on the white-male stereotypes of the time and demanded prior training and experience in science and engineering at a time when very few women or minorities were earning (or were allowed to earn) degrees in science and engineering. In 1973, then–NASA Administrator James Fletcher hired Ruth Bates Harris as a high-level deputy director to oversee NASA’s equal opportunity employment processes—but, when it turned out that she would be a fearless leader rather than a compliant bureaucrat, he red her and then, under pressure, attempted to rehire her at a lower level. This initiated bad press, conicts with Congress, and a series of internal struggles that brought about diversication. In the 1990s, Administrator Dan Goldin could complain that NASA was still too male, pale, and stale, although, two decades earlier, NASA had responded to new domestic political issues by changing from a civil rights sham to the beginnings of a demonstrably effective, if imperfect, afrmative action program. Aside from the 1965 selection cycle, when the National Academy of Sciences handled selection and allowed women to apply (none were accepted), it was not until the Shuttle era that women were added to the astronaut corps.

Some of the women who had participated in the informal wom - en’s astronaut selection program of the early 1960s felt vindicated in 1995, when they watched pilot Eileen Collins lift off, carrying their dreams with her. 78 Today, female astronauts routinely participate in Shuttle and Space Station missions in many different roles. Despite the long road that American women and minorities traveled to prove their worth, the U.S. experience has shown that talented women and minorities, given no special treatment because of gender or ethnicity, are as adept as their white, male colleagues in the world of space. PSYCHOLOGICAL SUPPORT Initially, psychological support for astronauts came from helpful ight surgeons, ak-catchers who tried to minimize interference on the part of the media and the public, as well as cheering family and friends. By means of shortwave radio, astronauts on the ground encouraged astronauts in orbit. It is clear from Wolfe’s The Right Stuff that the astronauts’ wives provided strong support for one another, as well as for their husbands. 79 The larger community of astronauts and their families still provides psy - chological support for astronauts before, during, and after their ights. Professional psychological support for the astronauts and their families evolved over time and gained momentum in the early space station era. 80 Today, psycho - logical support is provided in three stages: preight, in-ight, and postight. 81 78.

Family readiness is addressed in a brief - ing focused on the astronaut’s spouse to explain processes such as crew care pack - ages and private family conferences. Crew care packages are containers of personal items from family and friends that are sent via Russian Soyuz supply missions and U.S. Space Shuttle missions to astronauts residing on the ISS. Favorite foods, sur - prise gifts from the family, and holiday decorations are a few of the items that have been sent to the ISS in these shipments. During the ight stage, in addition to the crew care packages and private weekly videoconferences with families, psychological support services include extensive communication with people on the ground (including Mission Control person - nel, relatives, and friends), psychological support hardware and software, special events such as surprise calls from celebrities, and semimonthly videos with a behav - ioral health clinician. Astronauts in ight have e-mail accessibility and can use an Internet protocol phone on board the ISS to call back to Earth. As in the past, ham radio allows contact between the ISS and schools throughout the world. A month before their return to Earth, ISS astronauts are briefed on the stresses and joys of returning home following the deployment. Postight, there are a series of debriengs intended to benet the astronaut and ne-tune the psychological sup - port program. The astronaut’s spouse is given the opportunity to meet with opera - tional psychological support personnel to provide the latter with feedback on the psychological support provided during the mission. Of course, astronauts and their families can use counseling psychological support services at any time. While this briey covers the current state of the art of psychological support for astronauts on the ISS, psychological support for lunar and Mars missions may have greater con - straints and force a return to the mindset of earlier explorers and their families. CONCLUSION Spaceight is both demanding and rewarding, and for many years, psychol - ogists focused on the demanding environment and stressful effects. Throughout the history of spaceight, psychologists, psychiatrists, and many other professionals 42 Behavioral Health have expressed concern that the physical, psychological, and interpersonal stress - ors of spaceight could endanger a crew, undercut performance, and lower the qual - ity of life. Episodes in spaceight-analogous environments and a few incidents in space suggest that although no astronauts have been recalled to Earth on the basis of psychological and social challenges, adaptation must be taken into account. Astronaut participation in extended-duration missions, the prospects of a return to the Moon, continuing public enthusiasm for a mission to Mars, the reformula - tion of research questions following the publication of Safe Passage , and the coevo - lution of NASA’s Bioastronautics Critical Path Roadmap and the National Space Biomedical Research Institute initiated a new era for psychology. According to our analysis, since the dawn of the modern space station era, there has been an increase in both research and operational interest in spaceight behavioral health. Slowly, and perhaps painfully, psychology has gained greater recognition within the U.S. space program, and there is a growing convergence of interests to target research at operational problems. 82 Current NASA administration has mandated that human research be oper - ationally relevant. This is partly driven by funding shortages and partly by needs to meet NASA performance standards and requirements when astronauts once again venture beyond low-Earth orbit. The new Human Research Program docu - ments including the “Human Research Program Requirements Document” and the “Human Research Program Integrated Research Plan” are the bases for dening, documenting, and allocating human research program requirements as they have evolved from the older Bioastronautics Critical Path Roadmap and new NASA standards and requirements that emphasize future missions. As explained on the NASA Web site, “The Human Research Program (HRP) delivers human health and performance countermeasures, knowledge, technologies, and tools to enable safe, reliable, and productive human space exploration. This Integrated Research Plan (IRP) describes the program’s research activities that are intended to address the needs of human space exploration and serve IRP customers. The timescale of human space exploration is envisioned to take many decades. The IRP illus - 82. Albert A.

A comprehensive program in spaceight behavioral health will have to be broad-based; be interdisciplinary; and address issues at the individual, small-group, and organizational levels. It will require mul - tiple, convergent methods including archival research, eld observations, and both eld and laboratory experiments. Research falling under this umbrella must meet high scientic standards, achieve ight certication, and be palatable to astronauts. Only with continued interest and support from NASA—and from psychologists— will spaceight behavioral health ourish. Long-term success will require accessi - ble, peer-reviewed publications and efforts to target young investigators to replace those who retire. An ongoing behavioral database could prove very useful. For over 15 years, David Musson, Robert Helmreich, and their associates have been devel - oping a database that includes astronauts as well as professionals who work in other demanding environments. 84 As they point out, this kind of database provides many opportunities for studies in such areas as the effectiveness of recruiting and selec - tion procedures, performance changes over time, and attrition. Psychology is in a better position to be of help. Many of the theories and tools that are proving useful today were not available at the dawn of the Space Age. New (relative to 1960) resources include cognitive models, which emphasize our information processing power, and humanistic or “positive psychology” models that stress people’s positive, striving nature. 85 These new models have allowed psychol - ogists a fresh take on many important issues. Human factors psychologists bene - t from modern computer modeling technologies and increasing evidence of the importance of taking the person into account when developing a human or human- robotic system. 83.

Suedfeld, “Invulnerability, Coping, Salutogenesis, Integration.” 44 Behavioral Health Research technology has changed dramatically over the past 50 years, and the new technology has also been useful for increasing psychology’s contributions to NASA. These changes are evident wherever we look, from questionnaire construc - tion to data analysis. Today, miniaturization and computer technology enable psy - chological assessments and evidence-based countermeasures that would have been impossible in the 1960s. Minimally intrusive techniques are particularly useful, and one of these is based on nonintrusive computer monitoring of facial expression. 86 Another approach is mon - itoring cognitive functioning through computer analysis of speech. 87 Encouraging astronauts to monitor their own behavior reduces the threat that performance lapses could lead to ight disqualication. This self-monitoring has been accomplished by means of computers and personal digital assistants (PDAs) that are programmed to measure several dimensions of cognitive functioning (attention, information pro - cessing, and recall). Astronauts may use the results of these tests to gauge their own preparedness to engage in a particular activity. 88 While we see evidence of an expanding role, our profession’s future in space - ight is by no means assured. NASA’s resistance to psychology is by no means fully overcome. NASA Administrators must still concern themselves with public rela - tions. Project managers and engineers must still get on with their tasks within the real constraints of cost and practicality. Astronauts remain sensitive to possible threats to ight assignments and careers. The focusing events of Mir and the ISS were less than two decades ago, and it is too early to tell if the new interest and infrastructure can withstand the vagaries of funding variations or national and orga - nizational politics. 86.

Bishop Department of Preventive Medicine and Community Health and School of Nursing University of Texas Medical Branch ABSTRACT The need to nd relevant terrestrial substitutes, that is, analogs, for teams oper - ating in extraterrestrial and microgravity environments is driven by extraordinary demands for mission success. Unlike past frontiers where failure on the part of vari - ous groups to succeed represented far more limited implications for continued prog - ress within these environments, accidents like Challenger in 1986 and Columbia in 2003 underscored the magnied cost of failure for space missions. Where past human frontiers were characterized by centralized decisions to engage in exploration and development largely under the dictates of authoritarian governments or individual sponsors, the exploration of space has been signicantly inuenced by the general public’s perception of “acceptable risk” and scal worthiness. To date, space mis - sions have failed due to technological deciencies. However, history is replete with examples of exploration and colonization that failed due to human frailties, includ - ing those that reect failures of the group. Both historical literature and research on teams operating within extreme environments, including space, have clearly indi - cated that psychological and sociocultural factors are components critical for indi - vidual and group success. Given the limited access to the space frontier and the investment in collective effort and resources, our ability to study individual and group functioning in the actual space environment has been, and will continue to be, severely limited. Thus, studying groups in terrestrial extreme environments as analogs has been sought to provide predictive insight into the many factors that impact group performance, health, and well-being in challenging environments. This chapter provides an overview of the evolution of research utilizing ter - restrial analogs and addresses the challenges for selecting, training, and sup - porting teams for long-duration space missions. An examination of how analog 47 Psychology of Space Exploration environments can contribute to our knowledge of factors affecting functioning and well-being at both the physiological and the psychological levels will help dene the focus for future research. INTRODUCTION Humans have long speculated about, studied, and striven to explore the heav - ens. Many of our earliest myths, such as the ight of Daedalus and Icarus too close to the Sun on wings made of wax, expressed our desire to explore beyond the bound - aries of Earth as well as our willingness to push current technology to its limits. Considerations by the earliest philosophers and scientists, including Archimedes, Galileo Galilei, Nicolaus Copernicus, Leonardo da Vinci, Sir Isaac Newton, Jules Verne, H.G. Wells, or Percival Lowell, eventually generated a whole new genre of ctional literature built upon scientic extrapolations, dubbed “science ction,” and gave voice to their speculations about the nature of extraterrestrial environ - ments. Modern scientists and pioneers led by the Wright brothers, Robert Goddard, Konstantin Tsiolkovsky, Hermann Oberth, Wernher von Braun, Sergey Korolev, Yuri Gagarin, and Neil Armstrong pushed the boundaries of knowledge about ight and extended human inquiry beyond our terrestrial boundaries into our local and extended galactic neighborhood. For serious considerations of how humans will fare in space, we have had to extrapolate from human experience on Earth in envi - ronments that challenge us in, ideally, similar ways. However, the search for space analog environments in which to systematically study individual and group adap - tation has had to grapple with some signicant limitations, i.e., the impossibility of a substitute for a microgravity or reduced-gravity environment or environments that holistically mimic radiation proles and their inherent danger for those beyond Earth’s magnetic eld. Since there is no direct equivalent for space, all analog envi - ronments are simulations of greater or lesser delity along varying dimensions of interest. Some analog environments provide extremely good characterizations of expected challenges in testing equipment or hardware, e.g., environmental cham - bers such as the Space Shuttle mock-ups of the various decks or the cargo bay in NASA’s Weightless Environmental Training Facility (WET-F), but lack any rel - evance to assessing how human operators will fare psychologically or as a team. Others, like chamber studies, address important components of human adaptation, 48 From Earth Analogs to Space: Getting There from Here e.g., connement, but fail utterly to incorporate true environmental threats. Others allow for the impact of true dangerous, unpredictable environments but lack any way to systematically compare across specic environments. The spectrum of del - ity to space among terrestrial analogs ranges from laboratory studies where the impact of environmental threat and physical hardship, as well as true isolation and connement, are limited and, even, sometimes absent, to real teams in real, extreme environments characterized by very little control over extraneous variables. This, then, is the challenge. Unlike the testing of hardware, where various components can be reliably evaluated separately, the study of humans, and teams in particular, is a dynamic endeavor requiring in situ study of the collective. To develop reliable protocols based on empirical evidence to select, monitor, and sup - port teams effectively in space necessarily involves the demand to study teams in analog environments that replicate a wide range of physiological, psychological, and psychosocial factors interacting both with the environment and within the team. The high degree of reliance on technology for life support, task performance, and communication must be integrated with new measurement methodologies to overcome heretofore intrusive measurement modalities. The growing frequency of multinational and multicultural teams and the demand for longer-duration mis - sions both further compound the complexity of the challenge. While the primary goal has been the insurance of human health and well-being, the expectation has been that such priorities will naturally lead to improved chances for performance and mission success. Yet achieving this goal depends largely on how well our ana - logs prepare us for living and working in space. Analogs for human individual and group performance in space has involved two basic approaches: 1) constructing an environment within a laboratory setting with maximum control over extraneous variables and utilizing volunteer research subjects or 2) studying naturally occurring real-world groups in real environments characterized by a number of confounds. 1 Each comes with its own limitations and strengths. In any evaluation of the value of the analog, the pros and cons of each environment need to 1. W. Haythorn and I. Altman, “Personality Factors in Isolated Environments,” in Psychological Stress: Issues in Research , ed. M. Trumbull (New York: Appleton-Century-Crofts, 1966); J. P. Zubek, Sensory Deprivation: Fifteen Years of Research (New York: Appleton-Century- Crofts, 1969). 49 Psychology of Space Exploration be kept in mind. This is especially true when assessing the generalizability of insight of psychosocial factors from substitute environments for space. Before we began deliberately constructing controlled laboratory environments, there were the records of early expeditionary explorations into various places on Earth. 2 The tradition of publishing personal diaries and mission recounts has been similarly observed by the earliest explorers of space. 3 Secondary analyses of his - torical expeditions have become increasingly popular in recent years. 4 The very character of natural environments typically guarantees that there will be at least some, if not substantial, periods of inaccessibility, lack of communication or con - tact, little accessibility of real-time support, and great demands on individuals and groups to engage in autonomous decision-making, problem-solving, conict reso - lution, self-monitoring, and self-regulation. These demands inherently build in the potential for conict with external mission support personnel and researchers who nd adherence to mission schedules and timelines far easier to maintain than do those actually on the mission. Shared perspective between these groups becomes increasingly difcult to promote as mission duration, distance, and environmental demands play larger roles in daily decisions of the teams than do seemingly arbi - trary mission schedules. Measurement of these factors is compromised as teams become preoccupied with dealing with the environment, become antagonistic to external evaluation, become noncompliant with schedules that become unimportant to participants, and engage in a general reprioritization of activities that emphasizes near-term, more salient goals (e.g., personal comfort, leisure) over and above long-term mission goals (e.g., study data). Such difculties have raised questions about the worth of studying groups in real-world environments. In actuality, these conditions are exactly what is needed to simulate space missions that have grown in duration, 2. A.

However, space missions will also be, at least for the foreseeable future, characterized by an extraordinary degree of control, from selecting who goes to establishing the daily details of mission tasks and schedules—elements that are far more variable in real-world groups, such as those in Antarctica or part of polar or mountaineering expeditions. In real-world groups that have higher degrees of structure and control, such as military teams, the command and control structure is distinctly different from the current scientist- astronaut organizational structure of space missions. Fundamental differences in group structures, such as leadership and authority, represent signicant elements in whether ndings from terrestrial analogs translate to future space crews. The need for control over the inherent chaos of real-world environments in order to denitively identify critical factors that affect individual and group perfor - mance was the driver behind the development of constructed environments of vari - ous complexities. Useful data from such articial environments depend on whether participants are truly immersed in the ction of a simulation and are responding in the same way they would if the environment were real. This is the paradox researchers in analog environments face: In laboratory studies, the very attributes of the environment that have the greatest impact on performance are removed (e.g., real danger, uncontrolled events, situational ambiguity, uncertainty, or the inter - action with the extreme environment itself). If these features are compromised, as many have argued, then is there value in conducting such laboratory studies? 5 On the pro side, laboratory chamber studies have provided opportunities to evaluate methods of monitoring psychological and interpersonal parameters for subsequent application during real ights and have identied issues that might cause psycho - logical and interpersonal problems in space. They have also provided empirical evi - dence for a number of behavioral issues anecdotally reported from space, e.g., the tendency of crews to direct aggression toward personnel at Mission Control. 6 They 5.

However, com - plexity is a key dening trait of stressed operational environments. Total reliance on laboratory studies and the presumption of broad generalizability, particularly for research on high-stress, high-risk environments, is highly likely to lead to dissoci - ation between actual operational ndings and laboratory and experimental stud - ies. 7 Conversely, data on real-world groups situated in extreme environments has provided insight into a host of factors that impact group performance, health, and well-being emergent from the interaction between the individual, the team, and the environment. The differences found between studies conducted in experimen - tally controlled chambers and those conducted in messy, noisy, in situ real environ - ments appears to be due to the critical presence of real environmental threat and physical hardship, as well as true isolation and connement, which have proven to be key factors in individual and group coping. Additionally, when comparing extreme environments with non-extreme natural environments in which people normally operate, the level, intensity, rate of change, and diversity of physical and social stimuli, as well as behavior settings and possible behaviors within an extreme environment, are far more restricted. 8 Thus, real teams in extreme environments have validated or corrected ndings from chamber studies where critical environmental factors are typically absent or blunted. Real extreme environments allow us to examine various aspects of the psy - chophysiological relationship that are essential to fully understanding the adaptation Environmental Medicine 66 (1995): 617; V.

Space, of course, will be the nal testing ground for our accumulated knowledge. But are we stuck with choosing between chamber studies and naturally occurring opportunistic teams in real extreme environments? A more recent, hybrid approach of situating research facilities within extreme environments offers a good compromise between the articial conditions of the laboratory and the open-ended, full access of an expe - ditionary mission. When teams or individuals operate in extreme environments, their responses are more purely a product of either situational drivers or internal per - sonal characteristics. To the extent that an extreme environment is well character - ized and known, it gains in delity and allows more accurate inferences about key phenomena to be drawn. For these very reasons, Palinkas has strongly argued that the cumulative experience with year-round presence in Antarctica makes it an ideal laboratory for investigating the impact of seasonal variation on behavior, gaining understanding about how biological mechanisms and psychological processes inter - act, and allowing us to look at a variety of health and adaptation effects. 9 PSYCHOLOGY AND SPACE One important fact, which has emerged during decades of research, is that in the study of capsule environments there are few main effect variables. Almost every outcome is due to an interaction among a host of physical and social environmental variables and personality factors. Thus, although we conceptually deconstruct the situation into particular sources of variance, we must remem - ber that how people experience an environment is more impor - tant than the objective characteristics of the environment. 10 Investigations into psychological and psychosocial adaptation to extreme envi - ronments as substitutes for space are recent phenomena. Expeditions and forays 9. Palinkas, “On the ICE.” 10. P. Suedfeld and G. D. Steel, “The Environmental Psychology of Capsule Habitats,” Annual Review of Psychology 51 (2000): 230. 53 Psychology of Space Exploration into these environments have historically been for the purposes of exploration, and the primary metric of successful adaptation was survival. One could argue that chronicles such as the Iliad and the Odyssey were early examples of more recent dia - ries such as those that recounted the historic race to reach the South Pole between modern polar expeditions lead by Roald Amundsen, who reached the South Pole in 1911, and Robert F. Scott, who reached the South Pole in 1912. Humans have been periodically living and working in Antarctica, one of the most challenging envi - ronments on Earth, for over a hundred years. The rst winter-over in Antarctica occurred during 1898–99 on board an icebound ship, the Belgica , on which Amundsen served as a second mate. A continuous presence on our furthermost southern continent has only been in place since the International Geophysical Year of 1956–57. Systematic research on isolated, conned environments can arguably be dated as beginning as recently as the late 1950s by the military, and much of the early work focused on purely physiological parameters. In their seminal collection of papers dealing with isolated environments from Antarctica to outer space, A.A. Harrison et al. pointed out that early work on psychological factors in extreme envi - ronments is often recounted as beginning with C.S. Mullin’s research on states of consciousness; E.K.E. Gunderson and colleagues’ comprehensive work on adapta - tion to Antarctica; and classic laboratory studies on group dynamics conducted by I.Altman, W.W. Haythorn, and associates. 11 Regardless of which analog is used to understand what helps or hinders individ - uals and groups in functioning well under extreme environmental challenges, it is necessary to characterize what we need to know for space. Although specic condi - tions of the setting vary, most extreme environments share common characteristics: 1)a high reliance on technology for life support and task performance; 2)nota - ble degrees of physical and social isolation and connement; 3)inherent high risks 11.

The accumulated knowledge to date is still fairly rudimentary, given the short histor - ical emergence of the “Space Age.” Drawing on research from a number of elds (e.g., social psychology, human factors, military science, management, anthropol - ogy, and sociology), researchers easily identied a number of factors that need further investigation. As early as the 1980s, psychological and sociocultural issues had been acknowledged by the National Commission on Space (1986), the National Science Board (1987), and the Space Science Board (1987) to be critical components to mis - sion success, as robust evidence from Antarctica clearly showed psychological issues to impact human behavior and performance signicantly in most challenging envi - ronments, especially those characterized by isolation and connement. 13 Studies in a variety of analog environments, e.g., Antarctica, underwater capsules, submarines, caving and polar expeditions, and chamber studies, have conrmed that mission parameters have a signicant inuence upon the type of “best-t” crew needed and have isolated a number of psychosocial issues that may negatively affect crewmem - bers during multinational space missions. 14 These issues include 1)tension resulting 12.

Of particular uniqueness to challenging environments is the fact that successful performance requires com - petent team interaction, including coordination, communication, and cooperation. The functioning of the operational team often determines the success or failure of the mission. Experience in spaceight, aviation, polar, and other domains indicates that the stressors present in extreme environments, such as fatigue, physical dan - ger, interpersonal conict, automation complexity, risk, and confusion, often chal - lenge team processes. The contribution of interpersonal and intrapersonal factors is substantial. For instance, a robust body of evidence from both civilian and mili - tary aviation identies the majority of aircraft accidents as due to human and crew- related performance factors. 15 Analyses of critical incidents in medical operating Environmental Medicine 71 (2000): 619; S.L.

It is therefore critical that teamwork in these environments be examined and understood. A fundamental need to enable these investigations is developing reliable, minimally intrusive and valid methodologies for assessing individual and group responses to these stressors and identifying dysfunctional and functional coping responses. The use of extreme environments with characteristics relevant to those inherent in space travel and habitation will play a crucial role in preparing humans for egress from planet Earth. Given the disparate nature of these various environments, Peter Suedfeld has proposed ve key principles that may be useful guides in assessing the relevance of various extreme environments as viable analogs for space or providing the basis for cross-comparisons: Principle 1: Researchers should think in terms of experiences within environ - ments rather than of environmental characteristics; Principle 2: Researchers should study differences and similarities between experiences, which are not the same as those between environments; Principle 3: Analogies should be based on similarities of experience, not nec - essarily of environment; Principle 4: Research should look at systematic links between personality fac - tors and experience; and Principle 5: Experience is continuous and integrated. 17 Error,” International Journal of Aviation Psychology 7 (1997): 67; D.W.

The intent here is not to recite the spectrum of ndings across analogs within these areas, but to articulate how analog environ - ments can address these areas. • Selection issues deal with the evaluation of existing ability, trainability, and adapt - ability of prospective team members. It is not merely a matter of selecting-out pathological tendencies, but, as importantly, selecting-in desirable characteris - tics. How can analog environments allow us to investigate the impact of vari - ous individual and group characteristics upon individual and group performance? • The impact of isolation and connement has been shown to be signicantly impacted by various moderator variables, e.g., the difculty of rescue. While an emergency on the International Space Station certainly poses difculties regarding time to rescue, one can argue that the difculties inherent in a Mars mission or even here on Earth from the Antarctic in midwinter, where weather conditions may absolutely make rescue impossible for long periods, carry a qual - itatively different psychological impact. An emergency on a mission to Mars will preclude any chance of rescue and necessitate a high degree of autonomy for the crew in making decisions without any real-time mission support. The degree to which such factors magnify the negative effects of isolation and con - nement is critical to assess. • Group interaction and group processes are not a simple sum of the individuals that make up the group. Complex interactions can reinforce, undermine, or create new behaviors in the individuals involved. Identication of group fusion (fac - tors that encourage group cohesion) and ssion (factors that contribute to group conict) variables are elementary to creating habitats and work schedules, com - posing groups, and a myriad of other factors that will enable groups to function effectively and ensure individual and group well-being. For instance, in a study of Antarctic winter-over personnel, Palinkas found that personnel at Palmer (a small station) spent 60 percent of their waking hours alone and retreated to their bedrooms extensively for privacy. These behaviors could be considered s - sion factors as they promote withdrawal, social isolation, and distancing from one’s teammates. On the other hand, if the use of privacy served to control the amount of contact and decreased tensions and group conict, they would be 58 From Earth Analogs to Space: Getting There from Here considered fusion factors. He also found that intermittent communication was a major source of conict and misunderstanding between crews and external sup - port personnel, a clear source of ssion inuence. Examples of fusion factors for this group were effective leadership styles, which played a signicant role in sta - tion and crew functioning, as well as the ability to move furniture and decorate both common and private areas, which facilitated adaptation and adjustment. 18 • Individual and crew performance is perhaps the clearest, most frequently studied outcome. Yet there are challenges in dening what constitutes acceptable out - comes at both the individual and group levels. They are not always the same thing, as investigations into missions that failed to meet expectations have repeatedly conrmed. It is a mistake to try to assess and maximize performance without understanding group dynamics, the effects of isolation and connement or the environment in general on inhabitants. Given that our selection crite - ria have been little more than ruling out pathology and matching task require - ments with technical prociency within individuals, it is of little surprise that our efforts to implement performance improvements have been only modestly suc - cessful and fraught with inconsistent results. It is necessary to take the next steps to identify which individual and group characteristics are maximally associated with adaptation and functioning in these high-challengeenvironments. TERRESTRIAL ANALOGS FOR SPACE There are surprising similarities and differences found across environments. G.M. Sandal et al. found that coping strategies during connement on polar expe - ditions were different from those in hyperbaric chambers. 19 Whereas polar teams evidenced a delay interval with a marked drop in aggression until after the rst quarter, with concomitant increase in homesickness, chamber teams displayed a steady gradual increase in coping over time. A number of researchers have noted that it is not the site that seems to matter, but rather it is the differences in the mis - 18.

In fact, studies addressing Suedfeld’s Principle 4 investigating personality char - acteristics have produced supporting evidence for a focus on the experience as the dening factor rather than the environment per se. The most persistently investigated personality assessment for the last 15 years has been the NEO-PI by P.T. Costa and R.R. McCrae. 20 This instrument assesses ve global dimensions of personality: neu - roticism, extraversion, openness to experience, agreeableness, and conscientiousness. These dimensions have been found to be associated with the previous personality “right stuff/wrong stuff/no stuff” proles identied by Helmreich et al. in longitudi - nal studies of American astronaut candidate performance. 21 Additionally, measures of achievement motivation, interpersonal orientation, Type A, stress, and coping have been frequently evaluated. Recent studies have found evidence that agreeableness and conscientiousness seem to better predict performance at the global level, along with specic facets of extraversion. 22 Conscientiousness, extraversion, and agreeable - ness have been found to be related more strongly to constructive change-oriented communication and cooperative behavior than to task performance. Cognitive ability appears to be related more strongly to task performance than to constructive change- oriented communication or cooperative behavior. Results also demonstrate contrast - ing relationships for agreeableness (positive with cooperative behavior and negative with constructive change-oriented communication). 23 However, another personal - 20.

In other words, only individ - uals with this inward, self-focused personality would nd such challenges rewarding and be successful at these tasks. Similarly, an apparently adaptive personality prole has emerged from winter-overers that is characterized by low levels of neuroticism, desire for affection, boredom, and need for order, as well as a high tolerance for lack of achievement, which would t well in an environment where isolation and conne - ment prevented accomplishments and the participants experienced frequent short - ages and problems. 25 Those that would best adapt would be those who could more quickly adjust their expectations to the immediate situation and tolerate such obsta - cles. If this hypothesis is substantiated, then we must carefully match the character - istics of the individual to the environment as well as the group in order to maximize successful adaptation and performance.

Insomuch as it is possible to select for hardier and better-t per - sonalities by ltering individuals and teams through environmental challenges, selecting analogs with highly salient and relevant characteristics that match space mission proles (e.g., long versus short duration, stationkeeping versus expedition proles) will be important. The Expeditionary Analog Expeditions, by denition, revolve around movement. Expeditionary ana - logs (e.g., oceanic, polar, desert, caving, mountaineering) include various explor - atory goals that are characterized by moving from one place to another rather than inhibiting a locale. Historical exploratory expeditions typically involved long dura - tions (i.e., months to years) characterized by signicant known and unknown risks, broad goals, a high degree of situationally driven contingency decision-making, and expectations of autonomy and self-sufciency. Modern expeditions, in contrast, are typically of short duration (i.e., two weeks to three months), utilize the advantages of technology to minimize risks (e.g., weather forecasts to take advantage of the best weather of a region and satellite communications to maintain contact), are more narrowly goal-oriented and task-focused, and involve members with special - ized roles and skills. In both expeditionary scenarios, teams were/are formed around appropriate skill sets and availability and a notable lack of any attempt to screen individuals psychologically except for medical factors. Research on team function - ing is often secondary to expedition goals, personal goals, schedules, and contingen - cies. The expedition may be intended to recreate experiences of earlier explorers, such as the Polynesian Kon-Tiki oceanic traverse; set records or discover new terri - tory, e.g., discover a route to India or explore a cave system; achieve personal chal - lenges, such as climbing mountains or skiing to the North Pole; conduct scientic research, e.g., by means of oceangoing research vessels or polar ice drilling teams; or conduct commercial exploration, such as mineral and oil exploration. 26 26.
