In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

Space telescopes can offer us better, clearer views of the universe (and of our own planet) than Earth-based telescopes can, but getting these large, delicate pieces of equipment into orbit is tricky.

In this activity (pages 42-49), learners discover the methods and challenges of building nanoscale structures with macroscale equipment.
