I'd like to preface this question with the fact that I know very little about seismology. On the Insight page with the most recently taken photos, I found two images with data on them, and very little accompanying explanation of what I'm looking at.
Can somebody explain what the MS Paint looking spray-painted area actually is in this image?
Also, I'd like a little bit of clarification on what this image is showing us as well
, I understand this is the spectrogram of the first vibrations detected on Mars. The device hasn't been deployed yet according to the answers. Can somebody put a frame of reference around this for me?
