  22. Safety • Current Progress • Safety designs incorporated into PDR design • Good knowledge for what safety aspects must be included • Next Step • Safety courses in September • Safe parts-manufacturing • Safe handling of electrical components • Buddy System! • Prototyping • Future Plans • Follow DINO’s safety regulations Colorado Space Grant Consortium

  23. Subsystem Risk Assessment = low risk = medium risk = high risk = N/A Colorado Space Grant Consortium

  24. Contingency Plans Colorado Space Grant Consortium

  25. Issues and Concerns • Mass • Structures / Solar Panels do not have enough mass allocated to them • Others are swiftly approaching mass limits • Power • Loss of structural size – less room for body-fixed solar panels • Increased mission activation / deployable timeline • Close to budget • Complete all trade studies • Comm antenna • Science imaging design • Spacecraft configuration (FITS arrays locations) Colorado Space Grant Consortium
