Opportunity’s last Mars panorama is a showstopper

The Opportunity Mars Rover may be officially offline for good, but its legacy of science and imagery is ongoing — and NASA just shared the last (nearly) complete panorama the robot sent back before it was blanketed in dust.

After more than 5,000 days (or rather sols) on the Martian surface, Opportunity found itself in Endeavour Crater, specifically in Perseverance Valley on the western rim. For the last month of its active life, it systematically imaged its surroundings to create another of its many impressive panoramas.

Using the Pancam, which shoots sequentially through blue, green and deep red (near-infrared) filters, it snapped 354 images of the area, capturing a broad variety of terrain as well as bits of itself and its tracks into the valley. You can click the image below for the full annotated version.

It’s as perfect and diverse an example of the Martian landscape as one could hope for, and the false-color image (the flatter true-color version is here) has a special otherworldly beauty to it, which is only added to by the poignancy of this being the rover’s last shot. In fact, it didn’t even finish — a monochrome region in the lower left shows where it needed to add color next.

This isn’t technically the last image the rover sent, though. As the fatal dust storm closed in, Opportunity sent one last thumbnail for an image that never went out: its last glimpse of the sun.

After this the dust cloud so completely covered the sun that Opportunity was enveloped in pitch darkness, as its true last transmission showed:

All the sparkles and dots are just noise from the image sensor. It would have been complete dark — and for weeks on end, considering the planetary scale of the storm.

Opportunity had a hell of a good run, lasting and traveling many times what it was expected to and exceeding even the wildest hopes of the team. That right up until its final day it was capturing beautiful and valuable data is testament to the robustness and care with which it was engineered.
