Hello! Do you know any specific mass for the lightsail of Breakthrough Starshot? I've only found an mass-surface ratio for the lightsail.
"8.6×10−4 gram m−2" 8.6e-4/16^-2 equals to 0.22. 220mg. The same with multiplication instead of division gives me 3,35 micrograms for the sail, which sounds a little physics defying to me for a 16m² sail.

The sail is assumed to be nano-coated graphene. It would only probably be only a few (dozen) atoms thick.

It's a metamaterial made out of a Graphene-composite, most sources say few hundred atoms thick, which is still practically nothing when scaled up. But I want to know it's mass to calculate some numbers for Laser sails.
