## What you would see

In the foreground stretches a vast, pale concrete apron, almost empty, crossed on the right by a thin white painted line. Parked diagonally across the middle ground, pointing to the left, is an enormous white Boeing 747, seen from its front quarter. A horizontal blue stripe runs along its fuselage beneath two rows of small windows, and its rounded nose dominates the left side of the image. Mounted on top, like a second, smaller aircraft riding piggyback, sits the space shuttle: white and gray, with a dark, heat-worn underside, a blunt nose, a swept triangular wing, and a raised tail fin marked with dark details. Its scale only becomes clear against the 747 and the tiny ground vehicles below: a mobile stairway pressed against an open door, with two small human figures at the top, a dark service vehicle, and a luggage cart to the far left. The aircraft's four engines hang beneath long wings that extend toward the right. Above, a bright blue sky filled with scattered, wispy white clouds takes up half the frame, lit by clear daylight. In the far distance, a low line of trees closes the horizon.

## How to look at it

Start with the enormous nose of the 747 on the left, then follow the blue stripe until you find the small stair vehicle: that contrast gives you the true scale. Next, lift your gaze to the shuttle and notice its darkened underside, so different from the carrier aircraft's clean white surface. Finally, look for the tiny figures at the top of the stairs.

## Context

According to the source, this photograph by Sean Smith, dated April 17, 2012, and preserved by the NASA Image and Video Library, shows the space shuttle Discovery mounted atop a NASA 747 Shuttle Carrier Aircraft at Washington Dulles Airport. The source describes Discovery as the first orbiter retired from NASA's shuttle fleet. These specially modified 747s were used to carry orbiters piggyback between landing sites and launch or maintenance facilities, since shuttles could fly in space and glide back to Earth but could not travel such distances on their own power.

## Curious detail

Discovery completed 39 space missions, more than any other orbiter in NASA's shuttle fleet.

## Questions

- What does it say about a technology when its most advanced machine has to be carried by another, older machine?
- How does the presence of tiny people and ordinary service vehicles change your sense of the shuttle's scale and importance?
- What should happen to great exploration machines when they retire: should they keep working, or become objects of memory?

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

1. What color is the horizontal stripe that runs along the 747 fuselage under the windows?
2. How many engines are seen hanging under the long wings of the 747?
3. What object with tiny people is attached to an open door of the 747?
