This page intentionally left blank The Geology of Mars Evidence from Earth-Based Analogs With the prospect of a manned mission to Mars still a long way in the future, research into the geological processes operating there continues to rely on interpretation of images and other data returned by unmanned orbiters, probes, and landers Such interpretations are necessarily based on our knowledge of processes occurring on Earth Terrestrial analog studies therefore play an important role in understanding the origin of geological features observed on Mars This book presents contributions from leading planetary geologists to demonstrate the parallels and differences between these two neighboring planets, and to provide a deeper understanding of the evolution of the Solar System Mars is characterized by a wide range of geological phenomena that also occur on Earth, including tectonic, volcanic, impact cratering, aeolian, fluvial, glacial, and possibly lacustrine and marine processes This is the first book to present direct comparisons between locales on Earth and Mars and to provide terrestrial analogs for newly acquired data sets from Mars Global Surveyor, Mars Odyssey, Mars Exploration Rovers, and Mars Express The results of these analog studies provide new insights into the role of different processes in the geological evolution of Mars This book will therefore be a key

457 Preface: the rationale for planetary analog studies Just before I left to attend the June 2001 Geologic Society of London/Geologic Society of America Meeting in Edinburgh, Scotland, I received two e-mail messages The first was from a UK-based freelance science writer, who was producing a proposal for a six-part television series on various ways that studies of the Earth produce clues about Mars He requested locations where he might film, other than Hawaii I was amazed that he seemed not to be aware of all of the locations on Earth where planetary researchers have been studying geologic processes and surfaces that they believe are analogous to those on Mars In retrospect, his lack of knowledge is understandable, as no books were in existence on the topic of collective Earth locales for Martian studies and no planetary field guides had been published that included terrestrial analogs of the newly acquired data sets: Mars Global Surveyor, Mars Odyssey, Mars Exploration Rovers, and Mars Express [Historically, NASA published a series of four Comparative Planetary Geology Field Guides with four locales having analog features for comparison with Mars, each book on a different subject and area (volcanic features of Hawaii, volcanism of the eastern Snake River Plain, aeolian features of southern California, and sapping features of the Colorado Plateau) However, all of these books were based on Viking data, intended for researchers in the field, were not widely distributed, and are now out of print (NASA has not published any more field guides).] The second e-mail was from Science Editor Susan Francis of Cambridge University Press, requesting that I stop by their booth at the Edinburgh meeting to discuss a possible topic for a new book on the geology of Mars Following this e-mail correspondence, I came up with a topic that highlights the current research of geologists who study various environments on Mars using Earth-based analogs vii viii Preface: the rationale for planetary analog studies Planetary geologists commonly perform terrestrial analog studies in order to better understand the geology of extraterrestrial worlds, in order to know more about our solar system Especially Mars, because although the radius of Mars is about half that of the Earth, its gravity is about a third of our own, and the current Martian atmosphere is very thin, dry, and cold À it is the one planet in the solar system whose surface is most similar to our own The geology of Mars is characterized by a wide range of geological processes including tectonic, volcanic, impact cratering, aeolian, fluvial, glacial and possibly lacustrine and marine However, other than the ongoing processes of wind, annual carbon dioxide frosts, and impact cratering, most active geologic processes on Mars shut down millennia ago, leaving a red planet frozen in time Many of the almost perfectly preserved surface features and deposits of Mars appear visually very similar to analogous terrestrial locales, leading researchers to propose similar processes and origins for deposits on both planets In order to test their hypotheses, logically researchers visit and study these analog areas on Earth to determine characteristics that (1) provide evidence for the origin of surfaces on Mars and (2) can be detected by instruments and astronauts on current and future missions Currently, the Mars Global Surveyor, Mars Odyssey, and Mars Express spacecraft and onboard instruments continue to orbit the planet and acquire data, while the active Mars Exploration Rovers explore the surface of Gusev Crater and the Meridiani plains Recent data from these missions show that our earlier interpretations of Mars geology need to undergo expansion and revision In this book, examples of new insights into these processes on Mars underline the need for study of Earth processes and analogs and the application of these results to a better understanding of the geological evolution of Mars In addition, future rover and spacecraft missions are also being planned for upcoming launch opportunities Within the next 20 years, perhaps astronauts may be sent to Mars Missions to Mars are expensive It is necessary and cost effective to attempt to be certain that our mission instruments and personnel are equipped and trained to detect and discern the nature of Martian terrains before they are deployed on that planet Therefore, research geologists investigate terrestrial analog environments to develop criteria to better identify the nature of planetary deposits from remote surface measurements and orbiting spacecraft data The first chapter in this book by Jim Head discusses how our Viking-based view of Mars has changed based on the new data we are receiving from the current Mars missions The rest of the chapters detail how specific rocks and environments on Earth are studied in order to better interpret data from Mars I would like to thank all the authors that participated in this 446 Integrated analog mission design NASA-run summer field camp adjacent to the crater provided necessary logistical and scientific support 17.3.5 Remote science experiment design Local and trunk wireless networks As shown in Figure 17.3, the simulated rover tests required that the ATV operator in the Arctic remain in continuous data communication with a remote science team in California Building on previous work in wireless exploration networks (Gilbaugh et al., 2001), field communications with the rover/ATV were maintained via a tactical network of 802.11b repeaters, which were in turn connected to base camp by high-speed point-to-point digital spread-spectrum trunk radio links (Braham, 1999) A commercially leased 768 Kbps satellite link provided connectivity from the field camp to NASA-Ames Research Center Including transmission, error-checking, and buffering effects, the typical data transmission times from the rover back to NASA-Ames ranged from a few seconds for still images of rock specimens to 70 to 90 s or more for MB three-color panoramic images The rover tests were run with no added delays, as though they were being operated locally (i.e., from a surface habitat or Mars orbit) This arrangement was consistent with the goal of assessing tele-presence performance Figure 17.3 Local and trunk wireless datalinks from the FFC backroom to the rover A detailed case study of the Haughton remote science experiment 447 (also, it was not feasible to recruit scientists with the patience to voluntarily operate with inserted two-way 20-minute delays to/from the rover) Transmissions to/from the rover were therefore logged with timestamps and a separate post-facto analysis was conducted to construct a similar timeline with EarthÀMars delays inserted Virtual presence capability during rover tests One of the expected capabilities of a 2015-class rover and operations facility is some degree of virtual visual ‘‘presence’’ for the remote science team (whether on Earth or Mars) The Future Flight Central (FFC) facility at NASA-Ames is a full-scale (8 m diameter) virtual air traffic control tower with computergenerated projected 360° out-the-window visuals For this study, the FFC consoles were used to provide image displays (panoramas, targeted higher resolution images, close-ups of samples) to the science team, as well as compose commands for the rover Panoramic images from the rover were displayed on the FFC ‘‘windows,’’ creating a sense of visual immersion for the science team (Note: the returned imaging data can be processed to create a virtual environment through which a remote scientist can ‘‘move’’ and, in doing so, achieve a startling level of immersion: this capability was not available to the team.) Responsibilities for data capture (rover tests, maximum 3-hour runs): Science team: command traverses, image acquisition, and sample acquisition Maintain personal notes to be combined and turned into a 1À2 page written report afterwards Support staff: open and log communications between science team and ‘‘rover,’’ archive images by test run, by type, daily Rover operator: acquire images as commanded, dump local image files daily to CDs, clear the onboard storage daily, acquire samples as commanded Test director: note stop/start/locations, take GPS waypoints, count total number of samples at the end of each run Tests using HS prototype spacesuit Prototype spacesuits were provided through the Hamilton-Sundstrand Company (HS) Geologist test subjects were organized by the SETI Institute The HS suit, shown in Figure 17.4, was an unpressurized ‘‘engineering prototype.’’ Retired Shuttle suit gloves were used with the rigid torso assembly, but there were no leggings HS provided a crew of two to monitor the safety and health of the geologist test subjects and to transport and maintain the suit A real pressurized spacesuit would introduce significantly greater restrictions on the suit subject which were not quantifiable in this experiment 448 Integrated analog mission design Figure 17.4 Hamilton-Sundstrand prototype at Site T11 Responsibilities for data capture (human in suit, maximum 3-hour runs): Geologist in suit: audio recording of personal observations (in suit or external via RF), turned later into a 1À2 page summary; close-up images on camera; choose samples to retain (up to kg limit) Suit assistant: carry specimen bag, camera, and hammer Support staff: monitor geologist health and safety, download and archive camera images after each deployment, capture handheld video in the field Test director: note stop/start/locations, take GPS waypoints, count total number of samples at the end of each run ‘‘Shirtsleeved’’-geologist surveys Ground-truth surveys by unencumbered geologists were conducted beginning at identical site starting points as in the other test series An assistant carried cameras, tools, and samples Responsibility for data capture (unencumbered human, unconstrained test time): ‘‘Shirt-sleeve’’ geologist: written report Assistant: download and archive camera images Given the figures of merit, tallies of observations, conclusions, and hypotheses were compiled from each report Figure 17.5 shows a paragraph from a ‘‘raw’’ report and a corresponding breakout A detailed case study of the Haughton remote science experiment 449 Figure 17.5 Survey report and observation tally sheet 17.3.6 Case study results Four remote science team traverses, three simulated EVA traverses, two unencumbered geologist traverses The three-person science team assembled at NASA-Ames at the FFC facility during the week of 22 July 2002 A total of four tele-operated rover test runs were made over a week’s time at three separate sites (see Table 17.4) Weather conditions at the Haughton Crater site were poor throughout: this limited the number of sites visited, time spent at each site, and also reduced the contrast of the images returned from the four remote runs Better weather prevailed in the subsequent traverses to these same three locations by space-suited (Figure 17.4) and by unencumbered geologists However, no descriptive report was turned in by the suited participants at Site T9 or the ‘‘shirt-sleeved’’ visit to T11 (Table 17.4) 17.3.7 Discussion Although a comparative assessment of the scientific productivity of the several approaches to field exploration was carried out, this assessment should be viewed as highly preliminary because of the limited duration of the tests resulting from poor weather, technical difficulties, the lack of remote team 450 Integrated analog mission design Table 17.4 Field tests in July 2002 with teleoperated rover ID Date Location UTM-E UTM-N Stops Comments

commanded into comms hole at 2.5 h ‘‘safing procedure’’ Science team wanted multiple pans at each stop Found water Surprise starting point of landing ellipse à Lost comms at 1.5 h training, and the choice of scientifically less interesting sites within the Haughton Impact Crater Technical improvements include a reduction in the still-substantial latency of communications between the remote science team and the ATV, increasing the panoramic camera’s coverage to a full 360°, and providing the team with some imaging coverage during the traverses to maintain situational awareness The remote science team’s limited time (four days) operating the simulated rover without prior training meant that the tests were primarily a learning experience for the team rather than a real operational test Table 17.5 lists the science return (as defined above in Section ) from each test The elapsed times for the rover tests not include MarsÀEarth equivalent inserted time delays Assuming that commands would be grouped whenever possible and that communications were continuous between Earth and Mars, post-test analysis indicates that inserting delays into the transmission transcripts increased the typical test duration by a factor of five If team deliberation time were less for a Mars-based science team (likely of no more than two astronauts) compared to that typical for a large Earth-based science team then this factor might be more like twenty And, if Earth access to a rover were further constrained (i.e., only to typical Deep Space Network twice/day access periods), it is estimated that that would reduce productivity by roughly another factor of five Among the pre-selected metrics, the number-of-hypotheses metric proved not to be useful This was perhaps because during the short tests there were relatively few observations made by the remote science team from which A detailed case study of the Haughton remote science experiment 451 Table 17.5 Summary of 2002 field results

Averages by type Remote Suited Free 192 78 19 14 26 37 2 hypotheses could be drawn The most differentiation between the three test types proved to be in the total observation count The observation averages by test type show, as expected, that human geologists in shirtsleeves are far more productive than either spacesuited humans or tele-operated robots And, not surprisingly, simulated EVA crew were more productive than the 2015-simulated rovers even if operated from a Mars base with reduced latency compared to Earth-based operations Figure 17.6 shows the relative observational rates À observations per unit time, normalized Preliminary results imply that a local spacesuited human would achieve about 25 times the science productivity of a 2015-class Earth-controlled rover Given that 2015-class rovers are expected to be 10 to 20 times as productive as the current state-of-the-art (Mars Exploration Rover), this further implies a relative productivity advantage per unit time of around 300À400 times for local EVA vs current capability As sketched in Figure 17.7, rather than the rover becoming an extension of the remote human science team, the science team became more mechanistic in their planning and execution during the rover tele-operated tests Targets of opportunity were bypassed if they were not on the original traverse plan, or would significantly slow the arrival of the rover at its next waypoint Conversely, both the simulated suit subjects and shirt-sleeved humans diverted their traverses to cover nearby targets of interest (such as hydrothermal vents, or a large ejecta block containing macrofossils at site T11) We anticipate that, with more training and experience, the remote science team would rapidly learn to function more as they would in person in the field 452 Integrated analog mission design Figure 17.6 Observations per unit time for the given test cases Figure 17.7 Sketch of rover and human paths in field exploration Conclusions 453 17.3.8 HoRSE case study conclusions The authors re-emphasize the need to avoid inferring too much from this first experiment This study compares human exploration performance to that of a hypothetical 2015 rover at only three test sites in a single geological setting (Haughton Crater) Small changes in mission profile or in the rate of robotic technology maturation can easily skew results in either direction Given that three test points are far from enough to be significant, additional field tests of this type are needed Follow-on studies must address at least two needs: first, to incorporate all the lessons learned regarding technical implementation, team training, and metrics into an improved system Second, to add more data points to the field science evaluations begun in 2002, probably by finding an appropriate Mars analog site in the US desert southwest where weather conditions are better than at Haughton Crater A total of 8À10 three-way science site productivity comparisons between humans and robots would be the minimum needed to provide results that could be used with some confidence in future costÀbenefit tradeoffs and other mission planning activities 17.4 Conclusions Case studies like those discussed in this chapter illustrate a need for a more comprehensive Analog Missions Program Work to date has been driven by the needs or interests of specific researchers or projects, has generally been under-funded, and has therefore been limited in scope and level of integration Current plans for the human exploration of the Moon and Mars require the use of analogs for the development, testing, and integration of new exploration technologies, scientific methodologies, and operational protocols Analogs are also needed for training the astronauts and ground crews, researching the effects of planetary exploration on humans, and demonstrating readiness for flight Thousands of testbeds and independent scientific investigations refine each system and subsystem, and Analog Missions provide the opportunity to integrate systems together in higher fidelity simulations Some of these simulations will go beyond even the ‘‘full-up sims’’ of Apollo 17, using advanced technologies, automation, intelligent systems, new management techniques, new models of international cooperation, and new platforms in space Using the Earth and Moon as analogs for Mars will be one of the keys to meeting the needs in the next era of human exploration 454 Integrated analog mission design Acknowledgments The authors wish to thank Bill Muehlberger, Dean Eppler, and
