High Resolution Imaging Science Experiment

The High Resolution Imaging Science Experiment is a spacecraft camera instrument carried by the Mars Reconnaissance Orbiter that produces high-resolution images of Mars surface features, polar caps, stratigraphy, and landing sites. Developed by a team led at the University of Arizona and managed by the Jet Propulsion Laboratory, the instrument supports studies by investigators from institutions such as California Institute of Technology, Smithsonian Institution, Massachusetts Institute of Technology, and international partners including European Space Agency teams. It has informed missions and analyses associated with programs like Mars Science Laboratory, Mars Odyssey, Mars Global Surveyor, ExoMars, and operations for landed assets including Curiosity (rover), Perseverance (rover), and Opportunity (rover).

Overview

The instrument was proposed and built through collaborations including the University of Arizona’s Lunar and Planetary Laboratory, the Jet Propulsion Laboratory, and contractors such as Ball Aerospace and Lockheed Martin, with scientific guidance from investigators at Brown University, University of Colorado Boulder, University of California, Berkeley, California Institute of Technology, and Smithsonian Institution. It images at scales valuable for contextualizing observations from Mars Reconnaissance Orbiter instruments like the Compact Reconnaissance Imaging Spectrometer for Mars and the Mars Climate Sounder, and complements datasets from missions such as Viking program, Mars Pathfinder, Mars Odyssey, and Phoenix (spacecraft). Principal investigators, instrument team members, and users have presented results at conferences including American Geophysical Union, Lunar and Planetary Science Conference, and European Geosciences Union.

Instrument Design and Specifications

The optical design employs a large aperture telescope coupled to a charge-coupled device manufactured with heritage from projects at Ball Aerospace and patterned after telescopes used by observatories such as Palomar Observatory and Mauna Kea Observatories. The instrument’s focal plane and electronics were developed with contributions from teams at Lockheed Martin, Massachusetts Institute of Technology, and NASA Ames Research Center. Key specifications include panchromatic imaging capability at sub-meter scale, multiple filters for multispectral imaging, high data-rate downlink requirements coordinated with Deep Space Network, and precise pointing provided by Mars Reconnaissance Orbiter avionics derived from designs by Lockheed Martin and guidance from Jet Propulsion Laboratory. Components underwent testing at facilities such as Goddard Space Flight Center thermal vacuum chambers and vibration tables used by United States Air Force launch contractors.

Science Objectives and Discoveries

Primary objectives targeted geomorphology, sedimentary stratigraphy, aeolian processes, seasonal frost cycles, and potential glacial and fluvial features relevant to astrobiology and exploration. Results refined site selection for Mars Science Laboratory Curiosity (rover) at Gale Crater and Perseverance (rover) at Jezero Crater, and informed geological interpretations alongside datasets from Thermal Emission Imaging System on Mars Odyssey and orbiter radar instruments like SHARAD. Discoveries include identification of recurring slope lineae correlated with observations by European Space Agency teams, mapping of layered deposits comparable to analogs studied by Smithsonian Institution curators, detection of viscous flow features analogous to terrestrial glaciers studied in Antarctica and Greenland, and high-resolution stratigraphic records that advanced comparisons with formations examined by field teams at Grand Canyon, Mojave Desert, and Atacama Desert analog sites. The instrument’s images supported research cited in journals such as Science (journal), Nature (journal), Journal of Geophysical Research, and proceedings from American Geophysical Union meetings.

Data Products and Processing

Data products include panchromatic mosaics, multispectral products, stereo pairs for digital elevation models, and targeted subframing for rover operations. Raw telemetry is received via the Deep Space Network and processed by pipelines at Jet Propulsion Laboratory and the University of Arizona to produce calibrated data archived at distributed repositories used by teams from NASA, European Space Agency, Canadian Space Agency, and institutions like University of Oxford, Brown University, Cornell University, and University of Texas at Austin. Processing steps apply radiometric calibration, geometric correction tied to Mars Global Surveyor topography and datasets from Mars Orbiter Laser Altimeter, and photogrammetric techniques comparable to procedures employed at United States Geological Survey mapping centers. Public archives and mission data use policies facilitate use by investigators at Stanford University, Imperial College London, Max Planck Institute for Solar System Research, and other research centers.

Mission Operations and Flight History

Launched on an Atlas V from Cape Canaveral Air Force Station in August 2005 as part of the Mars Reconnaissance Orbiter payload, the camera began routine operations after aerobraking and orbit insertion maneuvers planned and executed by teams at Jet Propulsion Laboratory and Lockheed Martin. Over the mission lifetime the instrument supported targeted campaigns during global dust storms observed in cycles compared with records from Mars Climate Orbiter and Mars Global Surveyor, executed coordinated observations with Mars Express and Mars Odyssey, and provided reconnaissance for landing sites assessed by Mars Science Laboratory and ExoMars teams. Operations have been maintained through mission extensions overseen by NASA program offices and science management entities at California Institute of Technology.

Collaborations and Funding

Funding and oversight involved NASA Science Mission Directorate, the Jet Propulsion Laboratory managed by California Institute of Technology under contract to NASA, and academic partner support from institutions including the University of Arizona, Massachusetts Institute of Technology, Brown University, Cornell University, University of Colorado Boulder, and international collaborators from European Space Agency, Canadian Space Agency, and research institutes such as Max Planck Society and Centre National de la Recherche Scientifique. Industrial partners included Ball Aerospace and Lockheed Martin; launch services were provided by United Launch Alliance under contracts involving United States Air Force ranges. Scientific output has been disseminated through publication venues like Science (journal), Nature (journal), and conference series hosted by American Geophysical Union and Lunar and Planetary Science Conference.
