1. The bounded alpha for this small `Scout PowerSail', 0.89 to 1.61kg/kW is in good agreement with JAXA's most recent work on the PowerSail mission `OKEANOS', an explorer to the Jupiter Trojan asteroid. The JAXA team built a prototype showing a path to a 108.2kW array at ~1.30kg/kW, with potential to reach 0.84kg/kW.55, 56Though not directly stated, these arrays appear to be based off SOA CIGS technology (~10-12% efficiency AM0; ~110g/m2). Transformational Advancements: ≤TRL2, speculative, flight in >50 years
