  36. 36. Low Impact Docking System (LIDS)• Background – LIDS has been in advanced development since approximately 1996 – Baselined to have flight hardware complete in 2010 – To be used on first CEV launch to ISS with an APAS adapter – Fully androgynous system with both soft and hard capture features • Soft capture uses electromagnetic • Hard capture uses hooksJanuary 11, 2007 36
  37. 37. Active LIDS vs. Proposed Passive LIDS for AdapterActive LIDS• All passive functions plus: – Fully Androgynous – 6-DOF Soft Capture Platform – Electromagnets (soft capture) – Latches (hard capture) – Primary/secondary latch drives – Pyro sep system – Push-off system for sep – Seals• Avionics boxesPassive LIDS for Adapter• Passive functions – Soft capture ring • Guide Petals • Magnetic striker plates – Latch tabs (passive hooks) – Umbilical connectors and cables• Custom LIDS tunnel interfaces to APAS• Static structure to support soft capture ringJanuary 11, 2007 37
