SOCD Mission Purpose o o The purpose of this “path finder” mission is to demonstrate the feasibility of launching Cube. Sats from the Wallops 17” sounding rocket form-factor. Once ejected, the Cube. Sats will carry out experiments and return data via telemetry to mobile ground stations deployed at Wallops and existing ground stations in Kentucky.

Cube. Sat Standard NEEDS THE DRAWING FROM THE CDS o Started in 1999 through Cal. Poly and Stanford Universities. o Allows the use of higher risk components and encourages student innovation. o Must conform to 10 cm cube and weight less than 1 Kg. o Because of relatively cheap launch cost many universities have gained access to space. o Much shorter development schedules. o Planned missions include the first university payloads to be launch by NASA September 2008 Draft 26 March 2009 Draft V 1. 0 Kentucky Space Proprietary Information o 13

MK III (I’m not sure what to call it) o o o NEEDS DRAWINGS/PICS OF PPODS Adapted from a Cube. Sat deplorer developed by Cal. Poly. Has flight heritage from several previous Cube. Sat missions. Simple design with rail and spring system that assures insertion into space environment. Has three iterations of the initial design with the third, and revision that will fly, having larger access ports to the payloads. Made of 7075 -T 73 Aluminum and anodized with Teflon impregnation.
