Deep space one integration and test challenges: getting to the launch pad in the faster, better, cheaper world

Abstract

This paper describes the integration and test challenges of verifying and validating the avionics hardware and flight software which have been experienced in meeting the New Millennium Program Deep Space One (DS1) project's faster, better, cheaper requirements. This paper gives a high level overview of the development and application of the two flight system testbeds (DSI Hotbench), the testbed activities supported the DSI Spacecraft Assembly, Test and Launch Operations (ATLO), and the testing performed to prepare for and support post-launch mission operations. In the "Faster, Better, Cheaper" environment of the New Millennium Program, DSI Integration and Test (I&T) has defined new methods and decision criteria to meet our requirements and goals while assessing and minimizing the risk in the paths we have taken. Our successes and failures are largely yet to be seen as we approach our July 1 launch date. This paper describes the challenges that have been faced and some that have been overcome during the DSI I&T phase. It presents the risks that have been accepted in our attempts to test completely the DSI Avionics system in preparation for launch and mission operations.
