    Mars, invisible vision and the virtual landscape: immersive encounters with contemporary rover images

    Get PDF
    How do contemporary imaging devices and the forms in which images are displayed affect our perception of Mars? How are scientists and engineers visually exploring, experiencing and navigating this uninhabitable terrain? Can we better understand this virtual landscape through immersive imaging techniques, or are these simply illusions? At what point does the glitch invade these immersive spaces, throwing us back into the realm of the image? And finally, can the glitch be seen as a method towards another kind of visibility, enabling us to ‘see’ and encounter Mars in productive ways? Through the analysis of contemporary representations of the Martian terrain, Mars, Invisible Vision and the Virtual Landscape: Immersive Encounters with Contemporary Rover Images offers a new contribution to studies of the digital and virtual image. Specifically addressing immersive image forms used in Mars exploration the research is structured around four main case studies: life-size illusions such as panoramas; 3D imaging; false colour imaging; and the concept of a ‘Mars Yard’. The thesis offers a new understanding of human interaction with a landscape only visible through a screen, and how contemporary scientific imaging devices aim to collapse the frame and increase a sense of immersion in the image. Arguing that these representations produce inherently virtual experiences, their transportive power is questioned, highlighting the image as reconstructed – through the presence of a glitch, illusion is broken, revealing the image-as-image. This thesis takes an interdisciplinary approach in which scientific images are analysed through the prism of photography’s relationship to reality, theories of vision and perception, representations of landscape, and digital and virtual image theory. At the heart of this thesis is the act of looking; critical and speculative writing is used to convey immersive encounters with images at NASA and the Jet Propulsion Laboratory (USA); University College London’s Regional Planetary Imaging Facility; Airbus Defence and Space (UK); the photographic archive at the V&A; and the Panorama Mesdag (Netherlands). The research re-examines scientific forms of images against examples from the history of visual culture (be it art or popular culture) to draw parallels between different ways of seeing, representing and discovering the unknown. The eyes of the Mars rovers provide viewpoints through which we regard an alien terrain: windows upon unknown worlds. Rover images bridge a gap between what is known and unknown, between what is visible and invisible. The rover is our surrogate, an extension of our vision that portrays an intuitively comprehensible landscape. Yet this landscape remains totally out of reach, millions of miles away. This distance is an impenetrable boundary – both physically and metaphorically – that new technologies are trying to break. Mars, Invisible Vision and the Virtual Landscape offers a two-way impact, constituting a new approach to the relationship between real and imagined images in order to demonstrate that the real Mars, however it is represented and perceived, remains distant and detached

    Adams-Based Rover Terramechanics and Mobility Simulator - ARTEMIS

    Get PDF
    The Mars Exploration Rovers (MERs), Spirit and Opportunity, far exceeded their original drive distance expectations and have traveled, at the time of this reporting, a combined 29 kilometers across the surface of Mars. The Rover Sequencing and Visualization Program (RSVP), the current program used to plan drives for MERs, is only a kinematic simulator of rover movement. Therefore, rover response to various terrains and soil types cannot be modeled. Although sandbox experiments attempt to model rover-terrain interaction, these experiments are time-intensive and costly, and they cannot be used within the tactical timeline of rover driving. Imaging techniques and hazard avoidance features on MER help to prevent the rover from traveling over dangerous terrains, but mobility issues have shown that these methods are not always sufficient. ARTEMIS, a dynamic modeling tool for MER, allows planned drives to be simulated before commands are sent to the rover. The deformable soils component of this model allows rover-terrain interactions to be simulated to determine if a particular drive path would take the rover over terrain that would induce hazardous levels of slip or sink. When used in the rover drive planning process, dynamic modeling reduces the likelihood of future mobility issues because high-risk areas could be identified before drive commands are sent to the rover, and drives planned over these areas could be rerouted. The ARTEMIS software consists of several components. These include a preprocessor, Digital Elevation Models (DEMs), Adams rover model, wheel and soil parameter files, MSC Adams GUI (commercial), MSC Adams dynamics solver (commercial), terramechanics subroutines (FORTRAN), a contact detection engine, a soil modification engine, and output DEMs of deformed soil. The preprocessor is used to define the terrain (from a DEM) and define the soil parameters for the terrain file. The Adams rover model is placed in this terrain. Wheel and soil parameter files can be altered in the respective text files. The rover model and terrain are viewed in Adams View, the GUI for ARTEMIS. The Adams dynamics solver calls terramechanics subroutines in FORTRAN containing the Bekker-Wong equations
