## What you would see

At the center of the frame floats an irregular, lumpy celestial body, seen in three-quarter view against the deep blackness of space dotted with faint, tiny stars. It is not a perfect sphere; its outline is bulging and knobbly, with hollows and mounds that suggest a long history of impacts. The surface is densely pitted with craters of varying sizes, some with raised rims and shadowed floors, others more worn. Two large basins dominate the visible hemisphere, with steep walls and bluish shadows that emphasize the topography. Color is a patchwork of earthy and metallic tones: golden ochres and reddish browns intermingle with areas of bluish gray and dark silvery blue, as if rock and metal formed separate provinces. Light appears to come from one side, creating sharp highlights on metallic edges and dense shadows in lowlands, giving the surface a rugged, almost sculptural texture that looks both shiny and dusty. In the lower left corner the word «Illustration» appears in discreet lettering. The scale feels monumental despite the absence of any human reference; the surrounding empty void reinforces its cosmic isolation.

## How to look at it

First notice the contrast between golden and bluish areas and imagine them as separate rock and metal terrains. Then focus on the two large central craters and how light casts deep shadows there; that interplay reveals the volume and metallic texture the mission aims to measure.

## Context

This is a scientific illustration created in March 2021 by Peter Rubin for NASA / JPL-Caltech / ASU, according to source data. It depicts asteroid Psyche, about 226 kilometers wide, located in the main belt between Mars and Jupiter. It is the target of NASA's Psyche mission, which at that time was scheduled to launch in August 2022, arrive in 2026 and orbit for 21 months. Based on Earth-based data, scientists believe Psyche is a mixture of metal and rock; this rendering illustrates the hypothesis that the two materials form large, distinct provinces, as opposed to an alternative hypothesis of intimate mixing at a scale too small to see from orbit. The image was made to visualize that possible surface pattern.

## Curious detail

Unlike a photograph, this image is a visual hypothesis: scientists do not yet know whether Psyche's metal and rock are segregated into large patches as shown here or intimately mixed beyond orbital resolution, and solving that puzzle is a key goal of the mission.

## Questions

- What does it suggest to you that an asteroid could be largely made of metal rather than just rock or ice?
- How does your perception of space change when seeing such a detailed object floating in pure black emptiness?
- What visual clues would you use to tell a metallic area from a rocky one if you were the orbiting spacecraft?

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

1. In the image, what small English word can you read in the lower left corner?
2. How many large and very prominent basins stand out on the illuminated side of the asteroid?
3. Besides ochre and brown tones, what bluish and silvery color family appears in the zones suggesting metal?
