  1. CHARACTERIZATION OF THE MER LANDING SITES F. Scott Anderson and Tim Parker 3/21/02 LS Workshop

  2. Introduction • Goal: Constrain the highest resolution local topography, slope and pulse width of the surface of Mars at the 2003 Landing Sites • Why: • Current maps made by Anderson, Bridges, Golombek, and Parker fail to show fine detail due to the large range of topography • Wanted to understand topographic structure of features in MOC • Approach: • Extract MOLA topo, slope, and PW for each MOC image in LS ellipse

  3. Data • MOLA data through rangefinding shutdown (ap20333) • MOC images • All data through E06 (all others after MOLA shutdown) • Basemaps and ellipses provided by T. Parker • Some MOLA/MOC pairs: • Missed orbit of MOLA data • MOLA data not in MOC image • Total: • Hematite: 8 images • Melas: 11 images • Athabasca: 5 images • Gusev: 9 images • Isidis: 8 images

  4. Method: MOLA over MOC • Visualize association between MOC structure and MOLA topography for images crossing LS ellipse • Read MOC image and determine sclk start/stop of image, and orbit number • Search specific MOLA orbit for matching sclk times • Track has previously empirically found to be in line 1674 of MOC image
