  2. MRO Mission Overview Launch Interplanetary Cruise Approach and Orbit Insertion Aug 2005 Aug 2005 - Mar 2006 Mar 2006 Capture Orbit --- Period: 35 hrs Asc Node: 8:30 pm LMST LC-41 Atlas V-401 Aerobraking Primary Science/Relay Nov 2006 - Dec 2010 Mar-Sep 2006 Primary Science/Relay Orbit --- Period: 112 min Hp: 255 km Ha: 320 km, Frozen Ascending Node: 3:00 pm LMST (Sun-Sync) Science Data Acquisition/Return

  4. Data Return Comparison

  5. HiRISE Objectives HiRISE Capabilities at 300 km altitude • Study the full range of processes affecting the surface of Mars. • Precision mapping of future landing sites and rover traverses. Part of Upheaval Dome, Utah, 61 cm/pixel.

  6. Metering Structure Sunshade Focal Plane Electronics Baffle Tube Power Supply Spacecraft Structure Remote Electronics HiRISE Camera Installed on MRO

  7. HiRISE Ray Trace Focus Mechanism Primary Mirror Primary Mirror Baffle 2nd Fold Mirror 1st Fold Mirror Filters Focal Plane Focal Plane Electronics Secondary Mirror Tertiary Mirror Secondary Mirror Baffle

  8. HiRISE Focal Plane Assembly • 14 CCDs (2048 x 128 pixels): • 10 CCDs Form Red Channel (20,000 pixels) • 2 CCDs Form Blue-Green Channel (4000 pixels) • 2 CCDs Form NIR Channel (4000 pixels)

  9. Non-Flight Alignment Cube Near IR CCDs Lightweight Baseplate Broadband Red CCDs (10 Total) Blue-Green CCDs 14 CCDs Mounted to FPA Baseplate S/C flight direction

  10. Data Compression • Pixel binning (2x2, 3x3, 4x4, 8x8, 16x16) • Use to reduce data volume and/or increase SNR • Convert from 14 to 8 bits with Look-Up Tables (LUTs) • 28 stored tables, most non-linear • Can compute additional tables • Fast and Efficient Image Compression System (FELICS) • Lossless compression in hardware attached to Solid State Recorder (SSR). • Expect slightly < 2:1 compression on full-res images and slightly > 2:1 on binned images • Only compresses 8-bit images

  11. Spaccecraft Jitter: What’s the Problem? • TDI imaging with 1 radian IFOV is very sensitive to spacecraft motions: • Motion over time scales up to 12.7 msec broadens the PSF and reduces spatial resolution. • Motion over all time scales up to that of the full image (up to 6.5 s at full resolution) distorts the image geometry. These distortions are significant to stereo analyses and must be corrected to ~1/3 pixel to achieve 0.5 m vertical precision.

  13. 11 0.384 12 3 7 1 5 9 10 2 4 6 8 7.3 typ 13 14 Jitter and Geometry Knowledge from CCD Layout • Ground features in image data are correlated between overlapping pairs or triplets of CCDs. • 7.3 mm offsets are too large (608 rows or lines), so selected CCDs (see arrows) are offset by 32 rows (384 µm) and 3 CCDs are needed per solution. • There are 5 triplets of CCDs for 32-line solutions (1-2-3, 3-4-5, 5-6-7, 7-8-9, 8-9-10). • Some solutions could fail for lack of surface features or data gaps within 48 x 48 pixel areas. • Red CCD overlaps only 48 pixels wide. NIR and Blue-Green CCD overlaps of 4000 pixels provide high-reliability solutions every 1250 lines. • Solutions allow us to model the broadening of the PSF both cross-track and along-track to an accuracy of 1/5 pixel or better.

  14. Geometric Reconstruction Is Essential to Stereo Measurements • Image at left is an anaglyph of the simulated 48-pixel overlap with LMA jitter model (worst time period). • Colors indicate false topography without geometric reconstruction. • Preliminary results of simulations show high correlation accuracy for 48 x 48 pixel overlaps.

  17. Acquire ~1000 stereo pairs (50% with 2x2 binning) Digital Elevation Model (DEM) resolution ~1.2-2.4 m Require q1+q2 >15° for 0.2 m vertical precision Stereo Data Acquisition Left: Topographic model with 10-m contours of Mars residual south polar cap (Soderblom, Kirk, and Herkenhoff, 2002).

  18. MOC DEM with jitter: Jitter corrected: (cosmetic correction to MOC-derived model) Production of Digital Elevation Models (DEMs) • Work will be led by R. Kirk at USGS/Flagstaff. • Integrated Software for Imagers and Spectrometers (ISIS) used to correct image geometry. • Commercial photogrammetry software (SOCET SET) used to produce DEM. • ISIS/SOCET synergy is especially important for correcting errors in image orientation, which include • high frequency vibrations (“jitter”) —> undulations of DEM • absolute pointing/position errors —> offsets of DEM from true location In ISIS • HiJITTER: estimate pointing jitter by automatic matching of overlapping areas of CCD images; compare/combine with gyro data • HiGEOM: resample image data to remove jitter effects; also remove optical distortion & knit CCDs together into one image

  19. High-Resolution DEMs Will Enable Quantitative Geomorphology Controls on bedrock incision in the Grand Canyon are being studied with high-resolution DEMs by J. Pelletier et al.; see http://geomorphology.geo.arizona.edu//geomorphology.html Other things being equal, one effect of lithology is to increase stream gradients in strongly resistant bedrock such as in Hack's classic example of steeper gradients in sandstone than in shale of the Shenandoah Valley, Virginia. (From J. Pelletier’s class notes for Introduction to Geomorphology.)

  20. HiRISE and Surface Exploration • Past Landing Sites: • Viking (2), Pathfinder, MER (2) • Detailed orbital views may resolve arguments. • Ground truth for interpretation of orbital observations • Future Landing Sites • Candidate landing site evaluations for Phoenix and MSL; maybe other Scouts, sample return, human precursor missions • Meter-scale resolution and topography are essential to evaluate landing hazards and rover trafficability. • Active surface missions during MRO • Phoenix, MSL, others? • Precisely locate landers and rovers • Monitor surface changes

  21. “The People’s Camera” • HiRISE will welcome and encourage participation from all scientists and the general public: • Anyone may submit proposals for images. • Processed images, useful for science analyses, will be released ASAP, hopefully within weeks of acquisition. • These will be official PDS releases! • Web-based interface (HiWeb) • HiWeb will begin accepting target suggestions soon after launch. • HiRISE teams thinks this approach will result in the greatest possible science return: • We will image ~1% of Mars (0.1% at full resolution), so images must be carefully placed to address key questions. • The dataset is huge, so we want outside help for earlier discoveries, to influence future research and exploration.

  22. HiWeb Roles: • -Uplink: HiRISE Image Suggestions, Mars data perusal. • -Downlink: HiRISE image viewing, analysis & distribution • -Public website http://marsoweb.nas.nasa.gov/HiRISE • HiWeb development led by V. Gulick, NASA-Ames/SETI
