An apparatus, comprising: a first net extending from a first net center to a first net perimeter edge , said first net having a first net inner surface and a first net outer surface ; a second net extending from a second net center to a second net perimeter edge , said second net having a second net inner surface facing said first net inner surface ; a first reflector disposed at said first net outer surface ; a truss engaged to said first net at a first plurality of points along said first net perimeter edge , said truss engaged to said second net at a second plurality points along said second net perimeter edge , each of said first plurality of points being aligned with one of said second plurality of points ; and a truss deployment assembly including: a spool configured to rotate about a spool longitudinal center axis; and a plurality of ribs each having a rib length disposed between a corresponding plurality of rib first ends and rib second ends , said plurality of rib first ends coupled to said spool , said plurality of rib second ends correspondingly coupled to said truss , wherein said spool is configured to rotate about said spool longitudinal center axis to reversibly wind said plurality of ribs around said spool to radially extend or retract said plurality of rib second ends to move said truss between a truss stowed condition and a truss deployed condition . a first net extending from a first net center to a first net perimeter edge , said first net having a first net inner surface and a first net outer surface ; a second net extending from a second net center to a second net perimeter edge , said second net having a second net inner surface facing said first net inner surface ; a first reflector disposed at said first net outer surface ; a truss engaged to said first net at a first plurality of points along said first net perimeter edge , said truss engaged to said second net at a second plurality points along said second net perimeter edge , each of said first plurality of points being aligned with one of said second plurality of points ; and a truss deployment assembly including: a spool configured to rotate about a spool longitudinal center axis; and a plurality of ribs each having a rib length disposed between a corresponding plurality of rib first ends and rib second ends , said plurality of rib first ends coupled to said spool , said plurality of rib second ends correspondingly coupled to said truss , wherein said spool is configured to rotate about said spool longitudinal center axis to reversibly wind said plurality of ribs around said spool to radially extend or retract said plurality of rib second ends to move said truss between a truss stowed condition and a truss deployed condition . a spool configured to rotate about a spool longitudinal center axis; and a plurality of ribs each having a rib length disposed between a corresponding plurality of rib first ends and rib second ends , said plurality of rib first ends coupled to said spool , said plurality of rib second ends correspondingly coupled to said truss , wherein said spool is configured to rotate about said spool longitudinal center axis to reversibly wind said plurality of ribs around said spool to radially extend or retract said plurality of rib second ends to move said truss between a truss stowed condition and a truss deployed condition . <EOS>
