Final answer:
NASA scientists use infrared cameras to look for hot areas in a space shuttle during launch. Firefighters and building engineers also use infrared cameras for their respective purposes.
Step-by-step explanation:
When a space shuttle takes off, NASA scientists use an infrared camera to look for hot areas in the shuttle that might signal a problem. This camera is also used by firefighters, who can use it to identify hotspots and locate people in a burning building. Similarly, building engineers can use infrared cameras to identify energy leaks in a building's insulation and heating systems. In all these cases, the infrared camera is a valuable tool for detecting temperature differences and potential issues.
