  • Mars Reconnaissance Orbiter
    Chapter 6 Mars Reconnaissance Orbiter Jim Taylor, Dennis K. Lee, and Shervin Shambayati 6.1 Mission Overview The Mars Reconnaissance Orbiter (MRO) [1, 2] has a suite of instruments making observations at Mars, and it provides data-relay services for Mars landers and rovers. MRO was launched on August 12, 2005. The orbiter successfully went into orbit around Mars on March 10, 2006 and began reducing its orbit altitude and circularizing the orbit in preparation for the science mission. The orbit changing was accomplished through a process called aerobraking, in preparation for the “science mission” starting in November 2006, followed by the “relay mission” starting in November 2008. MRO participated in the Mars Science Laboratory touchdown and surface mission that began in August 2012 (Chapter 7). MRO communications has operated in three different frequency bands: 1) Most telecom in both directions has been with the Deep Space Network (DSN) at X-band (~8 GHz), and this band will continue to provide operational commanding, telemetry transmission, and radiometric tracking. 2) During cruise, the functional characteristics of a separate Ka-band (~32 GHz) downlink system were verified in preparation for an operational demonstration during orbit operations. After a Ka-band hardware anomaly in cruise, the project has elected not to initiate the originally planned operational demonstration (with yet-to-be­ used redundant Ka-band hardware). 201 202 Chapter 6 3) A new-generation ultra-high frequency (UHF) (~400 MHz) system was verified with the Mars Exploration Rovers in preparation for the successful relay communications with the Phoenix lander in 2008 and the later Mars Science Laboratory relay operations.

  • Operation and Performance of the Mars Exploration Rover Imaging System on the Martian Surface
    Operation and Performance of the Mars Exploration Rover Imaging System on the Martian Surface Justin N. Maki Jet Propulsion Laboratory California Institute of Technology Pasadena, CA USA [email protected] Todd Litwin, Mark Schwochert Jet Propulsion Laboratory California Institute of Technology Pasadena, CA USA Ken Herkenhoff United States Geological Survey Flagstaff, AZ USA Abstract - The Imaging System on the Mars Exploration Rovers has successfully operated on the surface of Mars for over one Earth year. The acquisition of hundreds of panoramas and tens of thousands of stereo pairs has enabled the rovers to explore Mars at a level of detail unprecedented in the history of space exploration. In addition to providing scientific value, the images also play a key role in the daily tactical operation of the rovers. The mobile nature of the MER surface mission requires extensive use of the imaging system for traverse planning, rover localization, remote sensing instrument targeting, and robotic arm placement. Each of these activity types requires a different set of data compression rates, surface Figure 1. The Mars Exploration Spirit Rover, as viewed by coverage, and image acquisition strategies.

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).

  • The Mars Science Laboratory Engineering Cameras
    Space Sci Rev DOI 10.1007/s11214-012-9882-4 The Mars Science Laboratory Engineering Cameras J. Maki · D. Thiessen · A. Pourangi · P. Kobzeff · T. Litwin · L. Scherr · S. Elliott · A. Dingizian · M. Maimone Received: 21 December 2011 / Accepted: 5 April 2012 © Springer Science+Business Media B.V. 2012 Abstract NASA’s Mars Science Laboratory (MSL) Rover is equipped with a set of 12 en- gineering cameras. These cameras are build-to-print copies of the Mars Exploration Rover cameras described in Maki et al. (J. Geophys. Res. 108(E12): 8071, 2003). Images returned from the engineering cameras will be used to navigate the rover on the Martian surface, de- ploy the rover robotic arm, and ingest samples into the rover sample processing system. The Navigation cameras (Navcams) are mounted to a pan/tilt mast and have a 45-degree square field of view (FOV) with a pixel scale of 0.82 mrad/pixel. The Hazard Avoidance Cameras (Hazcams) are body-mounted to the rover chassis in the front and rear of the vehicle and have a 124-degree square FOV with a pixel scale of 2.1 mrad/pixel. All of the cameras uti- lize a 1024 × 1024 pixel detector and red/near IR bandpass filters centered at 650 nm. The MSL engineering cameras are grouped into two sets of six: one set of cameras is connected to rover computer “A” and the other set is connected to rover computer “B”. The Navcams and Front Hazcams each provide similar views from either computer. The Rear Hazcams provide different views from the two computers due to the different mounting locations of the “A” and “B” Rear Hazcams.

It is based on mechanically realistic rover models and the use of classical terramechanics expressions to model spatially variable wheel-soil and wheel-bedrock properties. Artemis’s capabilities and limitations for the Mars Exploration Rovers (Spirit and Opportunity) were explored using single-wheel laboratory-based tests, rover field tests at the Jet Propulsion Laboratory Mars Yard, and tests on bedrock and dune sand surfaces in the Mojave Desert. Artemis was then used to provide physical insight into the high soil sinkage and slippage encountered by Opportunity while crossing an aeolian ripple on the Meridiani plains and high motor currents encountered while driving on a tilted bedrock surface at Cape York on the rim of Endeavour Crater. Artemis will continue to evolve and is intended to be used on a continuing basis as a tool to help evaluate mobility issues over candidate Opportunity and the Mars Science Laboratory Curiosity rover drive paths, in addition to retrieval of terrain properties by the iterative registration of model and actual drive results.

Advantages of a low profile for shielding Mars looks like Arizona but feels like Antarctica Rover Opportunity at edge of Endeavor Crater Designing railroads and trains for Mars Designing planes that can fly in Mars’ thin air Breeding plants to be “Mars-hardy” Outposts between dunes, pulling sand over them These are just a few of the Mars-related topics covered in the past 25+ years. Read on for much more! Why Mars? The lunar and Martian frontiers will thrive much better as trading partners than either could on it own. Mars has little to trade to Earth, but a lot it can trade with the Moon. Both can/will thrive together!

In short, particularly in safety-critical systems like unmanned vehicle Curiosity was sent to Mars in order to determine the planet’s operation. Thus, the ability to understand the components of risk habitability [1]. perception can be extremely valuable in developing either operational strategies or decision support technologies. To this The Curiosity rover left Earth on November 26th, 2011. end, this paper analyzes the differences in human supervisory Approximately nine months later, the MSL curiosity rover control of Mars Science Laboratory rover operation before and th after the discovery of wheel damage. This paper identifies four landed on Mars on August 6 , 2012.
