Evgeniya Khakhalova and Josh M. Feinberg IRM The main goal of many IRM visitors is to better understand the composition of the mag- netic remanence carriers in their samples. Typically, a material’s Curie or Néel temperature serves as the primary means for estimat- ing its mineralogical composi- tion. However, many of the most commonly used techniques, such as high temperature susceptibil- ity and thermal demagnetization experiments, have to be inter- preted carefully due to the com- plicating effects of grain size. For example, single-domain grains contribute less signal to suscep- tibility experiments than super- Fig 1.

A Retrospective Snapshot of the Planning Processes in MER Operations After 5 Years
A Retrospective Snapshot of the Planning Processes in MER Operations After 5 Years Anthony Barrett, Deborah Bass, Sharon Laubach, and Andrew Mishkin Jet Propulsion Laboratory California Institute of Technology 4800 Oak Grove Drive M/S 301-260 {firstname.lastname}@jpl.nasa.gov Abstract Over the past five years on Mars, the Mars Exploration Rovers have traveled over 20 kilometers to climb tall hills and descend into craters. Over that period the operations process has continued to evolve as deep introspection by the MER uplink team suggests streamlining improvements and lessons learned adds complexity to handle new problems. As such, the operations process and its supporting tools automate enough of the drudgery to circumvent staff burnout issues while being nimble and safe enough to let an operations staff respond to the problems that Mars throws up on a daily basis. This paper describes the currently used integrated set of planning processes that support rover operations on a daily basis after five years of evolution. Figure 1.

Calef1, R. G. Deen1, H. E. Gengl1, M. P. Golombek1, J. R. Hall1, O. Pariser1, M. Powell1, R. S. Sletten3, and the MSL Science Team. 1Jet Propulsion Labora- tory, California Inst of Technology ([email protected]), 2Malin Space Science Systems, San Diego, CA ([email protected] ), 3University of Washington, Seattle. Introduction: Localization is a process by which tactical updates are made to a mobile lander’s position on a planetary surface, and is used to aid in traverse and science investigation planning and very high- resolution map compilation. “Contextualization” is hereby defined as placement of localization infor- mation into a local, regional, and global context, by accurately localizing a landed vehicle, then placing the data acquired by that lander into context with orbiter data so that its geologic context can be better charac- terized and understood. Curiosity Landing Site Localization: The Curi- osity landing was the first Mars mission to benefit from the selection of a science-driven descent camera (both MER rovers employed engineering descent im- agers). Initial data downlinked after the landing fo- Fig 1: Portion of mosaic of MARDI EDL images. cused on rover health and Entry-Descent-Landing MARDI imaged the landing site and science target (EDL) performance.

Data are usually mission standards. Such a schedule requires rapid turnaround in understanding what happened during activities on the relayed through UHF frequencies to an orbiter at Mars previous Martian Solar Day (Sol).

Martian Rock Types Analysis of Surface Composition
Martian rock types Analysis of surface composition • Most of the knowledge from the surface compostion of Mars comes from: • Orbital spacecraft’s spectroscopic data • Analysis by rovers on the surface • Analysis of meteroites Southern Highlands • Mainly Basalts – Consists primarily of Olivine, Feldspars and Pyroxenes Northern Lowlands • Mainly Andesite – More evolved forms of magma – Highly volatile – Constitutes the majority of the crust Intermediate Felsic Types • High Silica Rocks • Exposed on the surface near Syrtis Major • Uncommon but include: • Dacites and Granitoids • Suggest diverse crustal composition Sedimentary Rocks • Widespread on the surface • Makes up the majority of the Northern lowlands deposists – May have formed from sea/lake deposits – Some show cross‐bedding in their layers – Hold the best chance to find fossilized life Carbonate Rocks • Formed through hydrothermal precipitation Tracks from rover unveil different soil types • Most soil consists of finely ground basaltic rock fragments • Contains iron oxide which gives Mars its red color • Also contains large amounts of sulfur and chlorine Tracks from rover unveil different soil types • Light colored soil is silica rich • High concentrations suggest water must have been involved to help concentrate the silica Blueberries • Iron rich spherules Meteorites on Mars What is a Martian meteorite? • Martian meteorites are achondritic meteorites with strong linear correlations of gases in the Martian atmosphere. Therefore, the gas trapped in each meteorite matches those that the Viking Lander found in Mar’s atmosphere. The graph below explains this correlation. • Image: http://www.imca.cc/mars/martian‐meteorites.htm Types of Martian Meteorites • 34 meteorites have been found that are Martian and they can be separated into 4 major categories with sub‐categories.
