Purpose of DR/ISTR

PLEASE READ:

For RS-X 2013, I am combining details needed for the DR at Wallops in March with the ISTR review. I am doing this because even after Post-CDR, I still do not have a clear understanding of each team’s final design. The purpose of the DR with Wallops is to capture the final design of both the rocket systems and the payloads (you) that are going to fly. The purpose of the ISTR is for me to understand how much of your design is built and how much of your design is tested. During RS-X 2012, each team had to complete a second ISTR before moving onto their Full System Test Review, where all subsystems have been tested and are now being tested together as a system. This review is scheduled to take place around March 18th, one month after this review. YOU MUST ADDRESS AND FOLLOW EVERY ASPECT OF THIS TEMPLATE DURING YOUR TEAM’S REVIEW THE WEEK OF FEBRUARY 18th. PLEASE CONTACT ME IF YOU HAVE ANY QUESTIONS
