HiRISE has been monitoring the InSight landing site for changes such as new dust-devil tracks, but the lander itself may appear different in each image.

" }, { "role": "body", "format": "html", "layout": "hipodMarginLayout", "text": "

This new image is our best view yet of the lander, clearly showing the two circular solar panels on either side of the lander body, and the bright spot which is the cover over the seismometer. Why is this lander image clearer than past images?

" }, { "role": "body", "format": "html", "layout": "hipodMarginLayout", "text": "

There are multiple contributors that improve the contrast. First, the air is clearer of dust this time of year. Second, this is an oblique view looking west, so the shadows are offset from the lander. Third, the illumination and viewing directions do not lead to any bright mirror-like reflections from the lander or solar panels, which can obscure surrounding pixels.

The seismometer cover to the south of the lander is still bright because its hemispherical shape always produces a mirror-like reflection over some small area.
