2、ion (EO-1) is a technology validation mission designed to flight-validate advanced imaging technologies applicable to a Landsat follow-on mission. It includes a pushbroom multispectral imager, a hyperspectral imager, an atmospheric corrector, and several spacecraft technologies applicable to future
3、remote sensing missions. The EO-1 advanced technologies are reflected in Figure 1.This figure, Figure 1 titled EO-1 Tecnologies, shows the list of advanced technologies considered for the New Millenium EO-1 mission.Provided by IHSNot for ResaleNo reproduction or networking permitted without license
4、from IHS-,-,-Lesson(s) Learned: Due to the risky nature of the advanced technologies to be flight-validated, we determined that our traditional project organization was not well suited to deal with this new kind of mission. More specifically, we identified the following shortfalls in our organizatio
5、n:1. We needed someone with insight into these new technologies who could devote all of their time to managing their maturation to flight status and to define the best way to validate them once on orbit.2. We needed additional help for the Mission Systems Engineer to devise a system and subsystem ar
6、chitectures to minimize the interaction between the advanced technologies and thereby maximize the likelihood of flight-validating them while remaining within the mission cost cap.3. We needed risk management well beyond what we would expect for a small science mission.Recommendation(s): Based on th
7、e above lessons learned, we make the following recommendations for future technology validation missions:1. Provide a full-time Mission Technologist to manage the technologies assigned to the mission for flight-validation.2. Provide sufficient system engineering to develop a cost-effective architect
8、ure that minimizes the interaction between the advanced technologies.3. Provide a Risk Manager to develop a more robust risk management than we typically employ.Evidence of Recurrence Control Effectiveness: Subsequent experience with other missions within the New Millennium Program has served to rei
