JAXA's photo of Hayabusa-2's capsule, at its landing on 2020 Dec 6, shows that its parachute canopy had some non-opaque sections. Why?
Transparency has no advantage for this mission. Compared to conventional parachute materials, transparent ones of the same strength tend to be heavier and less flexible. Or were these sections actually mesh, perhaps for stability at high speed?
One unauthoritative report claims, without elaboration, perhaps extrapolating from some rough diagrams circulating online, that
A cross-type parachute is used by the vehicle.
