  • Designed to simulate Mars rover operations
  • Deployed in Silver Lake, CA, area April 1999

FIDO Field Trial Accomplishments
  • Remote commanding by Core Operations Team (COT)
    using Web Interface for Telescience (WITS)
  • Approximately one gigabyte of data acquired,
    including Presidential Pan, near-simultaneous
    image and IR spectral data
  • Traversed over 300 meters using active hazard
    avoidance techniques based on Navcam planning and
    Hazcam stereo models
  • Mini-Corer acquired dolomite and meta-diorite
    rock cores

5
FIDO Field Trial Accomplishments
  • Several overnight Mössbauer measurements obtained
    using FIDO/arm in trailer
  • Numerous Raman Spectra of rocks and soils
    obtained in the RV using UAB PIDDP Raman
    Spectrometer
  • Rover controlled by high school science teams
    from Los Angeles, Phoenix, Ithaca, St. Louis as
    pilot educational activity called LAPIS

FY 99 FIDO Enhancements
  • Include gyroscope, accelerometer, and sun sensor
    data into telemetry for FIDO orientation and
    position as function of time
  • Include differential GPS as tool for
    independently tracking FIDO position
  • Generate stereo models for Pancam and Belly cam
    imaging systems
  • Improved S/N, faster acquisition times, and
    remove instrument artifacts for Infrared Point
    Spectrometer

16
FIDO FY99 Enhancements, Continued
  • Fix Pancam banding and determine MTF of system
  • Finish WITS implementation for arm deployment
  • Add shielded container for Mössbauer Spectrometer
    head
  • Improvements in Mini-Corer performance using
    yaw-pitch deployment
  • Update telemetry files to include information
    necessary to generate SPICE files, particularly
    rover position and orientation and instrument
    translation and rotation information as a
    function of time

17
FIDO Archiving and Analysis Plans
  • Back to Silver Lake with improved Pancam and IPS
    to finish collection of high quality imaging and
    spectroscopy for break-out channel walls.
    Probably September 1999
  • April mission results published on
    http//wufs.wustl.edu/rover
  • Digital Video Disk (DVD) to be published with
    documentation, data, field data (e.g., video)
    documenting April tests. Spin off educational
    (LAPIS) CD-ROM. Probably September 1999
  • Data analyses to help test procedures for ops
    analyses of Mars data, e.g., rock coatings

18
FIDO-Global Lessons-Learned
  • Orbital and descent data are crucial to providing
    regional geomorphic and geologic context
  • Ancient fluvial and lacustrine environment of
    Silver Lake
  • Strategic planning important to provide mission
    vision and objectives
  • Divided mission into sampling and
    exploration/discovery modules that provided
    context and schedule drivers
  • Tactical planning is equally important since
    events will not proceed as planned
  • Lots of rain and high winds led to continual
    re-planning
  • IPS hardware problems and the importance of
    on-site Raman Spectroscopy to determine dolomite,
    calcite, aragonite

19
FIDO-Global Lessons-Learned
  • Develop minimum success criteria to help in
    tactical planning
  • Successful core acquisition was of paramount
    importance, followed by traversing through
    complex terrain and acquisition of remote sensing
    and analytical data
  • Planning and quick look tools need to be
    interactive, intuitive and well understood by
    planners, maximizing visualization capabilities
    of humans
  • Led to preference for use of Rover Control
    Workstation system adapted for APEX/Athena
    instrument commanding since this system will be
    developed for flight (with appropriate
    configuration control) and has superior
    visualization capabilities

20
FIDO-Global Lessons-Learned
  • Use common formats from beginning to end
  • Will publish as PDS archive using SPICE kernels
    once we retrofit the data sets
  • Document as you go to avoid information loss and
    degradation
  • Loss of some sample context information because
    of the rapidity of the tests and the lack of
    documentation tools
  • Move expeditiously to flight-like operational
    conditions, even though time scale is compressed.
  • Move from WITS to RCW asap
  • Adopt SPICE kernels as standards
  • Time tags to delineate simulated uplink/downlink
    cycles

21
FIDO-Paramount Lessons-Learned
  • We can do the mission, including finding,
    sampling, and caching samples and then moving
    into an exploration and discovery mode!
  • Practice makes perfect. We would not send
    astronauts to Mars without extensive training.
    Similarly we need to continue to practice field
    operations with increasingly flight-like
    operating conditions (timescale excluded)

22
FIDO-Longer Term Enhancements
  • June 2001 include Athena-like Raman Spectrometer
  • Develop capability to command FIDO using Rover
    Control Workstation (RCW) system using command
    dictionary translator to and from FIDO and Athena

23
Future Field Work
  • One major blind field deployment per year for
    fy2000 and fy2001 with Core Operations Team (COT)
    sequestered off-site and remotely commanding FIDO
    to acquire and cache samples and to simulate
    exploration and discovery tasks
  • Two to three deployments per year in arroyo at
    JPL to test systems and operational concepts,
    e.g., SPICE tests
  • Monthly Mars Yard tests at JPL to test specific
    operational scenarios and procedures, e.g., test
    Athena operational scenarios
