I came across upper free flyer last night, while scanning the sky. All I
can say, is wow,

What someone who wrote on the project wrote awhile back.

Two dragsail systems were installed on the "Free Flyer" deployers used on
the SSO-A launch from 3rd December 2018 (
The free flyers separated from the launch vehicle and in turn deployed
multiple satellites each including Microsats and CubeSats over the course
of several hours. The Upper Free Flyer (NORAD ID: 43763) is a large
structure at approximately 1,000kg and the Lower Free Flyer is
approximately 260kg (NORAD ID: 43760). Each Free Flyer hosts one of our
16m2 aluminised kapton sail which was set to deploy 24 hours after launch.
