Abstract :

The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) Mars Lander Mission science goal is to understand the formation and evolution of terrestrial planets through investigation of the interior structure and processes of Mars. The science payload for InSight consist of a seismometer, heat flow probe and a precision tracking system to measure the size and state of the core, mantle and crust. Additional payload includes a meteorology package, a magnetometer, two color cameras and a 4 DOF robotic with a grapple at the end-effector. The InSight Instrument Deployment System (IDS) is comprised of the Instrument Deployment Arm (IDA), arm-mounted Instrument Deployment Camera (IDC), landermounted Instrument Context Camera (ICC) and control software. The IDS is responsible for precision instrument placement (seismometer and heat flow probe) on a planetary surface that will enable scientist to perform the first comprehensive surfacebased geophysical investigation of Mars. IDA has 1.9 m reach with four degrees of freedom: Yaw (shoulder azimuth) and three pitch joints (shoulder elevation, elbow and wrist). Each joint has a temperature sensor and heater with a dust seal to prevent contamination of the motor and gearbox. IDC allows visual confirmation of deployment steps, as well as acquisition of the stereo image pairs used to create a 3D map of the workspace. IDC also provides engineering images of solar arrays, payload deck and instruments. ICC provides context images and redundant worksite imagery. This talk will give a brief overview of InSight IDS and present test results and operations challenges for this first of kind instrument placement and installation on the Martian surface.
