The InSight science team has completed the deployment of the spacecraft’s seismometer by the placement of its protective domed shield over it.
The Wind and Thermal Shield helps protect the supersensitive instrument from being shaken by passing winds, which can add “noise” to its data. The dome’s aerodynamic shape causes the wind to press it toward the planet’s surface, ensuring it won’t flip over. A skirt made of chain mail and thermal blankets rings the bottom, allowing it to settle easily over any rocks, though there are few at InSight’s location.
The shield also helps protect the instrument from temperature changes.
With this deployment completed they will next deploy the heat flow package to the surface, where it will begin to drill its probe sixteen feet into the ground.
