Engineers at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, conduct power and functional testing on Dragonfly’s Integrated Electronics Module (IEM) and Power Switching Unit (PSU) in the cleanroom. The IEM houses the spacecraft’s core avionics, while the PSUs control and distribute power to Dragonfly’s instruments and systems. Dragonfly is NASA’s rotorcraft mission that will explore Saturn’s moon Titan, investigating the moon’s chemistry and habitability.
