  • Space programs have pioneered technologies such as medical imaging, including the computed axial tomography (CAT) scan and Magnetic Resonance Imaging (MRI) scanners.
  • Ear thermometers were developed and first used by space scientists. It is a camera-like lens that detects infrared energy emitted as heat.
