1、Lessons Learned Entry: 1795Lesson Info:a71 Lesson Number: 1795a71 Lesson Date: 2007-4-30a71 Submitting Organization: MSFCa71 Submitted by: Leslie CurtisSubject: NASA Mishap Investigation Report Review, application to LRO and LCROSS Abstract: One of NASAs earliest activities for implementing the visi
2、on for space exploration is the initiation of a series of robotic missions to the moon to prepare for and support future human exploration activities. The Exploration Systems Mission Directorate (ESMD) is sponsoring two robotic missions to the moon in late 2008. The Lunar Reconnaissance Orbiter (LRO
3、) will spend at least one year in low, polar orbit gathering data to map the lunar surface. LRO will collect the highest resolution and most comprehensive data set ever returned from the moon to help achieve NASAs goal of returning human explorers safely to the moon. The Lunar Crater Observations an
4、d Sensing Satellite (LCROSS) will investigate the presence and nature of water ice on the moon by impacting a lunar crater and observing the ejecta plume created. The LCROSS mission will provide valuable information about the existence of water on the moon, which will be used for future human lunar
5、mission designs. To help ensure the success of these two important missions, an assessment of previous NASA missions which had mishaps or failures was performed. Mishap Investigation Board (MIB) Reports were reviewed for eight missions, and the root causes and contributing causes of these mission mi
6、shaps were organized into recurring areas or themes. The recurring causes for these mishaps were reviewed with emphasis on potential application to LRO and LCROSS. It is hoped that this assessment of past missions that experienced mishaps and failures will prove valuable to the LRO and LCROSS projec
7、t teams. Description of Driving Event: This report was written with the objective of researching, reviewing, and consolidating NASA failures that would potentially be of interest to the LRO and LCROSS project teams for consideration. By reviewing previous failures and mishaps the LRO and LCROSS proj
8、ects may increase their ability to achieve mission success.Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-Lesson(s) Learned: The goal for NASA is to achieve mission success in all of its projects and programs. To accomplish this goal proven engineer
9、ing and design processes must be used, accompanied by adequate reviews and a healthy test and verification program. Risks must be constantly assessed and accounted for during implementation of the project. NASA has accomplished many missions successfully and there have also been quite a number of mi
10、ssion mishaps which could have been avoided. An assessment of recent mission mishaps should prove valuable to preventing a similar occurrence on future missions.Recommendation(s): The importance of the LRO and LCROSS missions to the Vision for Exploration is recognized by the project teams as well a
11、s organizations within NASA. Much help and advice has been and will be offered to these two projects as they work through the implementation phase. It is hoped that this assessment of past missions that experienced failures and mishaps will prove valuable to the LRO and LCROSS project teams. There i
12、s always value in looking at what NASA has done and learning from the failures and successes of previous missions.Evidence of Recurrence Control Effectiveness: N/ADocuments Related to Lesson: Click here to download document.
