## What you would see

A large, irregular asteroid dominates the center of a deep black space flecked with faint, distant stars. The body has a lumpy, potato-like silhouette with a heavily cratered and craggy surface. Multiple impact craters mark the visible face, including a pair of small, sharp, dark-rimmed bowls near the upper center and a larger, softer depression to their left, all casting subtle shadows. The terrain is highly textured, with jagged ridges, pitted plains, and blocky outcrops. Color shifts with topography: sunlit crests glow in warm tan, beige and rusty brown, while shadowed slopes and lowlands turn to cool slate-blue and charcoal gray, suggesting a blend of rocky and metallic materials. Light appears to strike from the upper left, sculpting strong highlights and deep blue shadows that emphasize roughness and relief. In the lower left corner, the faint word «Illustration» is barely visible against the black background. There is no atmosphere or horizon, only the solitary, 226-kilometer-wide world suspended in darkness, conveying both immense scale and quiet isolation.

## How to look at it

First take in the whole silhouette against the starry void to feel its isolation. Then follow the light across the surface from the bright upper edge into the deep blue shadows below. Look closely at the paired craters near the top; their contrast between highlight and shadow holds the clue to the imagined metal-rock texture.

## Context

This is a scientific illustration created in March 2021 by artist Peter Rubin for NASA/JPL-Caltech/Arizona State University, catalogued as PIA24472. It depicts the 226-kilometer-wide main-belt asteroid (16) Psyche, located between Mars and Jupiter. Based on Earth-based data, scientists believe Psyche is a mixture of metal and rock. This view illustrates one hypothesis: that metal and rock are intimately mixed on a scale too fine to resolve from orbit, as opposed to a companion illustration (PIA24471) showing large distinct provinces. At the time, NASA's Psyche mission was scheduled to launch in August 2022, arrive in 2026, and orbit for 21 months to study composition, topography and magnetic field with a magnetometer, multispectral imager and gamma-ray and neutron spectrometers.

## Curious detail

If Psyche is indeed a stripped planetary core, studying it from orbit could help scientists understand how Earth and other rocky planets formed their own metallic cores, without being able to visit them directly.

## Questions

- How does knowing this is an informed guess rather than a photograph affect how you trust the image?
- What might the coexistence of shiny metal and dull rock on one surface tell us about violent collisions in the early solar system?
- How does the emptiness around the asteroid shape your sense of time and scale?

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

1. In the lower left part of the image, what English word, almost hidden against the black background, indicates this is not a photograph?
2. According to the data sheet, how wide is this irregular potato-shaped body?
3. What two materials form the intimate mixture that this illustration wants to show on the surface?
