About

Masashi Iwashita is a pioneering aerospace engineer whose work centers on space-based microwave power transmission and large-scale orbital structure deployment. His research addresses one of the most ambitious challenges in space technology: constructing enormous antennas in orbit for applications like Solar Power Satellites (SPS), which could one day beam clean energy to Earth. Iwashita’s major contributions stem from a series of groundbreaking rocket experiments using the innovative "Furoshiki" deployment system—a concept inspired by the Japanese wrapping cloth, where a flexible membrane is unfurled in space and supported by small robotic modules. His 2009 paper on microwave power transmission via the S-310-36 sounding rocket, with 14 citations, remains a key reference in the field, demonstrating the first integrated test of deployment and power beaming. Earlier work in 2004 and 2006 further validated the feasibility of constructing huge transmitting antennas with robotic assistance. Though citation counts are modest, Iwashita’s experiments represent critical proof-of-concept milestones for SPS and large space structures, influencing subsequent research in space robotics and wireless energy transfer. His work exemplifies the bold, hands-on experimentation needed to turn visionary space concepts into reality.
