Powering Up Dragonfly’s Electronics

From left, Carlisa Drew, Seth Harvey, Anthony Fanelli, Emory Toomey and TJ Lee conduct power and functional testing on Dragonfly’s Integrated Electronics Module (IEM) and Power Switching Unit (PSU) in the cleanroom at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland. The IEM is Dragonfly’s “brain,” containing the spacecraft’s core avionics; the PSUs control the flow of power to Dragonfly’s instruments and systems.
