Deep Impact Delta II Launch Vehicle Cracked Thick Film Coating on Electronic Packages Technical Consultation Report
The Deep Impact spacecraft was launched on a Boeing Delta II rocket from Cape Canaveral Air Force Station (CCAFS) on January 12, 2005. Prior to the launch, the Director of the Office of Safety and Mission Assurance (OS&MA) requested the NASA Engineering and Safety Center (NESC) lead a team to render an independent opinion on the rationale for flight and the risk code assignments for the hazard of cracked Thick Film Assemblies (TFAs) in the E-packages of the Delta II launch vehicle for the Deep Impact Mission. The results of the evaluation are contained in this report. Cameron, Kenneth D. and Kichak, Robert A. and Piascik, Robert S. and Leidecker, Henning W. and Wilson, Timmy R.

To Reach the High Frontier
Access -- no single word better describes the primary concern of the exploration and development of space. Every participant in space activities -- civil, military, scientific, or commercial -- needs affordable, reliable, frequent, and flexible access to space. To Reach the High Frontier details the histories of the various space access vehicles developed in the United States since the birth of the space age in 1957. Each case study has been written by a specialist knowledgeable about the vehicle described and places each system in the larger context of the history of spaceflight. The technical challenge of reaching space with chemical rockets, the high costs associated with space launch, the long lead times necessary for scheduling flights, and the poor reliability of the rockets themselves show launch vehicles to be the space program's most difficult challenge.
NASA
NASA has long relied on the Delta II medium class launch vehicle (MCLV) to launch science missions. Delta II, however, is no longer in production, and no other vehicle in the relative cost and performance range is currently certified for NASA use. This report assessed: (1) NASA's and the contractor's steps to ensure resources are available to support safe Delta II oper. through 2011; (2) NASA's plans and contingencies for ensuring a smooth transition from current small and MCLV to other launch vehicles; (3) the risks associated with NASA's planned approach to fill the MCLV capability gap; and (4) technical and programmatic implications if NASA commits to new launch vehicles before they are certified and proven.
