Submit a Lesson Learned

Submit lessons learned to Please provide a point of contact (POC) with your submittal. We will contact the POC for additional and/or clarifying information if needed during the review process. Although we will accept and make every attempt to validate anonymous submittals, the lessons learned submittals that we are unable to validate will be discarded. Unless granted permission otherwise, we will not identify individuals submitting lessons learned. Public Lesson Learned Submittal Form (MS Word)

Before accepting a lessons learned, we will validate each submittal to ensure that:

  • It meets the needs of the commercial space transportation industry;
  • It is factually and technically correct; and
  • Its recommendations identify a decision, design, or process that prevents the recurrence of an unsuccessful outcome or promotes the recurrence of a successful outcome.

The review also ensures the removal of all sensitive information and approves the document for public release.
