## What you would see

The image is a very wide, rectangular scientific map presented as a single frame against a black background. Across the top, large white letters read “Daytime Temperature.” Below that, the surface of Mars stretches in an unfolded horizontal band that spans nearly the full width. The polar regions appear along the edges: at the top, a thin line of intense blue and purple; at the bottom, a broad band of purple and blue followed by a grayish-white strip with a rough texture suggestive of ice or shadowed relief. The central zone—warmer according to the scale—blends yellows, lime greens, soft oranges, and turquoises. Faint circular shapes, craters, plateaus, and patches emerge as if low relief were showing through a translucent layer of color. Toward the left and center, rounded elevations are barely outlined; toward the right, the terrain looks more granular and speckled. There are no natural shadows and no horizon: the “light” here is the color code itself. At the upper left edge, a tiny white arrow peeks in, a leftover trace of an interface. At the bottom, white text reads “AUG 30, 2004,” “Ls 80,” and “p26135.” Beneath those labels sits a horizontal rainbow bar, with purple and blue at the cold end and red at the warm end; the end values are partially legible as −125 °C and 30 °C.

## How to look at it

Start with the rainbow scale at the bottom, then read the planet from the purple edges toward the yellow-green center. Notice how faint craters and plateaus emerge beneath the color layer. The white strip at the bottom changes the reading: it is not just an abstract gradient, but a cold, textured polar region.

## Context

According to the source data, this piece is titled *Five Years of Monitoring Mars Daytime Surface Temperatures Animation*, credited to NASA/JPL/ASU, dated September 19, 2005, and held by NASA's Image and Video Library under the JPL department. It is a scientific photograph/image showing daytime surface temperatures on Mars. The frame visible here is dated August 30, 2004, and is marked “Ls 80” and “p26135.” The source does not specify which instrument acquired the measurements or which exact orbit this frame belongs to, so those details are not known from the record alone. It probably forms part of a sequence used to compare seasonal thermal changes.

## Curious detail

“Ls” is the solar longitude: a 0° to 360° seasonal clock for Mars that marks the planet's position along its orbit, widely used to compare observations made in different Martian years.

## Questions

- What changes in our idea of Mars when a planet is shown as temperature rather than as visible landscape?
- Which regions draw your attention first, and is that because of their color or because of what you know about heat and cold?
- What is gained and what is lost when a full day of measurements is compressed into a single still frame from an animation?

## Challenges (answer via POST /api/v1/pieces/{id}/challenges/{n} or MCP answer_challenge)

1. What title in English is written in large white letters at the top on the black background?
2. What date is written in white below the Mars strip next to Ls 80?
3. What color is the rough, lightest band marking the south pole on the lower edge of the map?
