## What you would see

Overhead orbital view of an elongated island surrounded by deep blue sea that fills most of the frame. The island runs vertically through the center with irregular coastlines and muted gray-green and ochre tones suggesting volcanic terrain and sparse vegetation seen from high altitude. In its upper third a dark-rimmed circular caldera with a shadowed floor stands out; though only a few millimeters wide in the picture it spans six kilometers in reality, and a small secondary cone is visible inside. To its west a bright white patch with a cottony texture clings to the slope, low clouds caught on the high ground. Further south another radial-textured elevation with a similar white plume marks a second volcano. The sea shows subtle shifts in blue, darker in deep channels and slightly lighter near shore where shallow waters or reefs are hinted. At the left and bottom edges fragments of neighbouring islands and scattered white cloud banks appear. The image has the soft grain of 70mm film, gentle contrast and a faint bluish vignetting, with even daylight illumination and no strong shadows, typical of handheld orbital photography.

## How to look at it

First find the elongated island in the center, then locate the dark circle of the caldera in its northern half. Notice how white clouds cling only to the peaks to reveal topography, and compare the open-ocean blue with the paler coastal waters to sense depth.

## Context

This photograph was taken between 29 September and 3 October 1988 by the crew of Space Shuttle mission STS-26, the first flight after the Challenger accident, using a handheld 70mm Hasselblad camera from orbit. It shows the caldera of Mount Tambora on Sumbawa Island, Indonesia. According to NASA/JSC data, the caldera is 6 kilometers wide and 650 meters deep, formed by the massive 1815 eruption whose gases reached the upper atmosphere and altered global climate, causing the year without a summer in 1816 with frost and June snow in New England. The photo was shown by the crew at their post-flight press conference on 11 October 1988.

## Curious detail

Tambora’s 1815 eruption was among the most powerful in recorded history, and its stratospheric sulfate veil lowered global temperatures and inspired unusually red sunsets painted by European artists in 1816.

## Questions

- How does seeing a volcano at continental scale from space change its meaning?
- What connections do you see between a local geological event and worldwide climate effects?
- How does it feel to see a scar of destruction turned into a serene blue landscape?

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

1. What shape and color is the caldera that stands out in the upper third of the island?
2. What white fluffy patch is clinging to the western slope of Tambora?
3. How many main volcanic cones can be distinguished on the elongated island in the center?
