InSight's Marsquake Detector Gets a Nifty Dome to Protect It From the Harsh Martian Environment

A dome placed over InSight’s seismometer will now protect the sensitive device from Martian wind and extreme temperature fluctuations.

Since NASA’s stationary InSight lander made it to Mars on 19 December, mission controllers have been steadily deploying its various instruments.

During the past several weeks, the team has been adjusting the Seismic Experiment for Interior Structure, otherwise known as SEIS.

Yesterday, the space agency issued a release highlighting the latest accomplishment in the mission—the placing of a protective dome-like covering, called the Wind and Thermal Shield, over the Marsquake detector.

On Earth, seismometers are buried about four feet underground to protect them from the elements.

The InSight probe isn’t capable of digging a sufficiently large hole, but it does have a robot arm, which it used to place the protective covering over SEIS.
