1Program Implementation Plan Review. This is an initial meeting to describe the plan for implementing the Commercial Crew Integrated Capability Program, to include management planning for achieving CDR; Design, Development, Testing, and Evaluation activities; risk management to include mitigation plans, and certification activities planned during the CCiCap Base Period.August 2012Complete$30 Million
2Integrated System Baseline Review. The Integrated System Baseline Review (ISBR) demonstrates the maturity of the baseline CTS integrated vehicle and operations design of the Dream Chaser Space System (DCSS) consisting of Dream Chaser spacecraft, Atlas launch vehicle, Mission Systems, and Ground Systems supports proceeding with the detailed CTS design.October 2012Complete$45 Million
3Integrated System Safety Analysis Review #1. The purpose of the Integrated System Safety Analysis Review #1 is to demonstrate that the systems safety analysis of the Dream Chaser Space System (DCSS) has been advanced to a preliminary maturity level, incorporating changes resulting from the Preliminary Design Review, The DCSS consists of the Dream Chaser spacecraft, launch vehicle, ground systems and mission systems.January 2013Complete$20 Million
4AEngineering Test Article Flight Testing. At least one free flight of the Engineering Test Article to characterize the aerodynamics and controllability of the Dream Chaser Orbital Vehicle outer mold line configuration during the subsonic approach and landing phase.April 2013Complete$7 Million
5SNC Investment Financing #1. This funding represents SNC’s commitment for significant investing financing. SNC to provide program co-investment of [REDACTED].July 2013Complete$12.5 Million
6Integrated System Safety Analysis Review #2. The purpose of the Integrated System Safety Analysis Review #2 is to demonstrate that the systems safety analysis of the Dream Chaser Space System.October 2013Complete$20 Million
7Certification Plan Review. The Certification Plan Review defines the top level strategy for certification of the DCSS that meets the objectives for the ISS Design Reference Mission described in CCT-DRM-1110 Rev Basic. SNC shall conduct a review of the verification and validation activities planned for the Dream Chaser Space System (Dream Chaser spacecraft, Atlas launch vehicle, Ground and Mission Systems).November 2013Complete$25 Million
8Wind Tunnel Testing. The purpose of this testing is to reduce risk on both the DC vehicle and the DC/Atlas stack by maturing the DC and DCiAtias aerodynamic databases, providing improved fidelity in Reynolds number effects and control surface interactions, and will help determine pre-CDR required updates to the OML or control surface geometry if required.February 2014Complete
$20 Million
9Risk Reduction and TRL Advancement Testing. The purpose of these tests is to significantly mature all Dream Chaser systems to or beyond a CDR level.May 2014Complete
$17 Million
9AMain Propulsion and RCS Risk Reduction and TRL Advancement Testing. The purpose of these tests is to significantly mature the Dream Chaser Main Propulsion System and Reaction Control System to or beyond a CDR level. Risk reduction and Technology Readiness Level improvement tests will be completed for these systems.May 2014Complete
