1 AstroMesh -Lite (AM -Lite)

2 AM -Lite Configuration • Meter Optimized Mass Design for 3 to 8- AM -1 6 to 25- Meter – -1 heritage configuration 50% reduction over AM Class AM -Lite -1 designs Same deployment kinematics as AM & AM • Meter 3 to 8- Class • Swivel Axis Hinge minimize the non- recurring cost for changes in reflector optics Reduce Reflector The shape of the ellipse is determined by the webs in the reflector – Mass by 50% surface and the rim truss follows that shape. The rim does not require radial stiffness. – Detailed parts remain the same regardless of F/D or aperture between 3 and 8 meters. Allows the truss to stow in a circular shape so that all stowed – trusses can use the same tie downs. 27 lbs 6 -Meter Reflector Light enough to lift with one finger

3 High Frequency Performance Independently Tested Northrop Grumman Near Field Range at Space Park • NGST Near Field Testing Fixed Truss with 20 & 30 OPI Mesh – – Frequency Range 18 to 65 GHz – Measured beam location and beam width match predictions Antenna efficiency*: 66% at 32 GHz, 61% at 40 GHz for – 5-meter reflector NASA Glenn Research Center Near Field Range in Cleveland, OH – Independent Test Verification • NASA Glenn Research Deployable Truss, 40 OPI mesh – Pre & Post Deployment Measurements – Frequency Range 30 to 50 GHz – Laser Radar Surface Mapping – Antenna efficiency*: 55% at 31 GHz & 45% at 50 GHz for 5.2- – meter reflector * Antenna efficiency includes feed performance
