A major scientific interest
Beyond this anecdotal Martian weather report, the data transmitted by the APSS sensors will serve above all a very essential scientific cause: the seismic study of the Red Planet, as Don Banfield points out:
“APSS will help us filter the background noise caused by the environment in the seismic data and know when we will observe a Martian earthquake, and when that will not be the case. By operating continuously, we will also get a more detailed view of the weather than most surface missions, which usually collect data only intermittently during a Martian day. “A weather regularly marked by events still mysterious: the “Dust Devils”, dust whirlwinds characterized by a local pressure drop, and which can now be detected thanks to the ultra-sensitive sensor InSight, and its cameras.
“Our data has already shown that there are many Dust devils at the [probe] location. Having such a sensitive pressure sensor allows us to observe the passage of more of them, “concludes Don Banfield. Scientists dreamed about it, NASA did it!
