The Must Know Keys to any Great Case Study Presentation maximum megahertz project case study

On the NASA rover mission to Jezero crater, the remote determination of the texture, mineralogy and chemistry of rocks is essential to quickly and thoroughly characterize an area and to optimize the selection of samples for return to Earth. SuperCam operates at remote distances, primarily 2—7 m, while providing data at sub-mm maximum megahertz project case study mm scales. The instrument is made up of three separate subsystems: the Mast Unit is designed and built in France; the Body Unit is provided by the United States; the calibration target holder is contributed by Spain, and the targets themselves by the entire science team.

This publication focuses on the design, development, and tests of the Mast Unit; companion papers describe the other units. The goal of this work is to provide an understanding of the technical choices made, the constraints that were imposed, and ultimately the validated performance portfolio examples the flight model as it leaves Earth, and it will serve as the foundation for Mars operations and future processing of the cas.

On a mobile robotic mission to explore in-situ ancient sedimentary and aqueously altered deposits in a potentially habitable environment Mustard et al. This coordinated search will reveal the processes and environments responsible for the chemical alteration of primary igneous materials, their recycling as sedimentary rocks in an aqueous environment e.

Introduction

The suite provides a highly synergistic analysis of rocks and soils. The greatest discoveries are likely to be made at the crossroads of the different techniques Fig. Mast-Unit investigations and overall objectives. MIC: Microphone. The RMI and VISIR investigations can also observe targets at longer distances, up to the crater walls a few tens of kilometers awaydepending on atmospheric opacity.

Along with these long-distance capabilities, SuperCam also operates at fine scales. As shown later, this is at maximum megahertz project case study scale of major features of interest for the mission, including mineral grains and rock textures. Several observation points on the same target may be necessary to explore its spatial heterogeneity. Combining small investigation scales and large rasters, SuperCam returns a large quantity of information in relatively low data volume. Most SuperCam observations are performed in less than 2 min per point, per investigation.

The possibilities of combining the different investigations are numerous and provide the science team with many options for analyses. Thanks to this rapidity, SuperCam is expected to study many targets, including several around each location where maximum megahertz project case study are selected for Earth-return to fully characterize the diversity of their geological context.

SuperCam possesses these same capabilities, except that the RMI images will be in color. The different investigation methods of SuperCam operate seamlessly and with techniques usually being coordinated successively for optimized sample analysis. Moreover, when shooting the LIBS laser, the plasma expansion generates a shock wave, which both removes dust and can also be recorded with the SuperCam microphone, providing information on the physical properties of the stealth bomber in action Chide et al. This publication is the first of three which describe the SuperCam instrument and its expected performance for exploring Jezero crater, Mars.

First, it introduces the SuperCam science objectives in the context of the Mars rover mission Sect. In a methodical way, these objectives lead to science requirements, then to an instrument concept that can be accommodated on the rover, and finally, an overall architecture Sect.
