The research project, known as the Microwave Array for Power-transfer Low-orbit Experiment (MAPLE), is one of three ongoing initiatives conducted on board the SSPD-1. The effort involved the utilization of two separate receiver arrays and lightweight microwave transmitters equipped with custom chips. Caltech’s team further emphasized that the design of the transmission setup aimed to minimize fuel requirements for space travel and necessitated flexibility to enable folding the transmitters onto a rocket.
