Results from the Mars Phoenix Lander Robotic Arm experiment
[1] The Mars Phoenix Lander was equipped with a 2.4 m Robotic Arm (RA) with an Icy Soil Acquisition Device capable of excavating trenches in soil deposits, grooming hard icy soil surfaces with a scraper blade, and acquiring icy soil samples using a rasp tool. A camera capable of imaging the scoop interior and a thermal and electrical conductivity probe were also included on the RA. A dozen tren...
متن کاملReproducing Meteorological Observations at the Mars Phoenix Lander Site Using the Nasa Ames
The mission began in late Spring (L s ~77˚) and ended in midSummer (L s ~148˚), lasting for 151 sols [2]. In situ measurements by the lander characterized the local atmospheric conditions (i.e. temperature, pressure, wind speeds and direction, opacity of dust and water ice, and the detection of surface water ice frost) [3,4]. Phoenix measured a steady decline in near surface atmospheric pressur...
متن کاملThe MECAWet Chemistry Laboratory on the 2007 Phoenix Mars Scout Lander
[1] To analyze and interpret the chemical record, the 2007 Phoenix Mars Lander includes four wet chemistry cells. These Wet Chemistry Laboratories (WCLs), part of the Microscopy, Electrochemistry, and Conductivity Analyzer (MECA) package, each consist of a lower ‘‘beaker’’ containing sensors designed to analyze the chemical properties of the regolith and an upper ‘‘actuator assembly’’ for addin...
متن کاملMars Surveyor '98 Lander MVACS robotic arm control system design concepts
This paper describes the control system design concepts for the Mars Volatiles and Climate Surveyor (MVACS) Robotic Arm which supports the scientiic investigations to be conducted as part of the Mars Surveyor '98 Lander project. Solutions are presented to some of the problems encountered in this demanding space application with its tight constraints on mass, power, volume, and computing resourc...
متن کاملMars Science Laboratory Robotic Arm
The Mars Science Laboratory Robotic Arm (MSL RA) is a critical, single–fault-tolerant mechanism in the MSL science mission that must deliver 5 of the rover’s 12 science instruments to the Martian surface. This paper will describe the design, build, and test methodology which evolved as the science payload matured over the course of the 4-year project. Lessons learned based on the EM and Flight ...
