THIS DIRECTED PROPOSAL PRESENTS A WORK PLAN AND COST ESTIMATE FOR CONTINUING THE JOURNALS FLIGHT EXPERIMENT, WHICH CONCLUDED SUCCESSFULLY IN APRIL OF 2010; THE PROPOSAL REQUESTS SUPPORT AND AUTHORIZATION TO RECRUIT TEN ADDITIONAL ASTRONAUTS TO MAINTAIN CONFIDENTIAL JOURNALS WHILE SERVING AS MEMBERS OF SIX-PERSON CREWS ONBOARD THE INTERNATIONAL SPACE STATION (ISS) AND TO PERFORM A SYSTEMATIC ANALYSIS OF JOURNALS CONTENT. THE ULTIMATE OBJECTIVE OF THE STUDY IS TO PROVIDE DATA-DRIVEN RECOMMENDATIONS TO INFORM DECISIONS CONCERNING THE PRIORITIES THAT SHOULD BE PLACED ON THE VARIOUS BEHAVIORAL ISSUES TO PREPARE FOR AND MANAGE FUTURE SPACE EXPEDITIONS. STUDY RESULTS CAN BE APPLIED TO IMPROVE SELECTION, TRAINING, SUPPORT, SCHEDULING, AND THE DESIGN OF EQUIPMENT AND PROCEDURES.
