The PTD 2 (Pathfinder Technology Demonstrator) is a 6U CubeSat technology demonstration mission to flight qualify and characterize a novel thruster provided by Tethers Unlimited, Inc., which uses electrolyzed water as fuel for a small thruster.
Each PTD mission consists of a 6-unit (6U) CubeSat weighing approximately 12 kilograms and measuring 30 cm × 25 cm × 10 cm. Each PTD spacecraft will also be equipped with deployable solar arrays that provide an average of 44 watts of power while in orbit.
It was selected in 2018 by NASA to be launched as part of the ELaNa program.
