DEMONSTRATION INPUT PACK · Coverage Review Kit v1.0.0

This is a human-annotated teaching example, not an AI benchmark or a review of NASA’s actual PR goals. The three messages below are invented demonstration goals. Only the listed excerpts are reviewed; absence means absent from these excerpts, not the full article.

Audience: General readers learning what an asteroid-deflection test demonstrated.
Objective: Explain the measured result and its limits without presenting a test as an immediate threat response.

Intended messages (demonstration goals, not NASA campaign claims):
1. The mission demonstrated asteroid deflection.
2. The measured orbital change was 32 minutes, with about two minutes of uncertainty.
3. These particular asteroids were not a threat to Earth.

REVIEW SCOPE: Only the following selected excerpts, not the complete article. A-prefix = article; R-prefix = NASA reference. All are exact short quotations.

A1 · Article headline
NASA's DART impact changed asteroid's orbit forever in planetary defense test

A2 · Opening, paragraph 2 (short excerpt)
although NASA knows of no such threats in the foreseeable future

A3 · Opening, paragraph 3 (short excerpt)
shortening Dimorphos' nearly 12-hour orbit by a whopping 32 minutes

A4 · Body, paragraph beginning “The DART spacecraft” (short excerpt)
which cost about $314 million

R1 · NASA release, paragraph beginning “Prior to DART’s impact” (short excerpt)
the spacecraft’s impact altered Dimorphos’ orbit around Didymos by 32 minutes

R2 · Same NASA paragraph, final sentence
This measurement has a margin of uncertainty of approximately plus or minus 2 minutes.

R3 · NASA release, paragraph beginning “Neither Dimorphos”
Neither Dimorphos nor Didymos poses any hazard to Earth before or after DART’s controlled collision with Dimorphos.
