Based on prior studies of cost growth in NASA and Department of Defense projects, this book identifies specific causes of cost growth associated with NASA Earth and space science missions and provides guidance on how NASA can overcome these specific problems. The recommendations in this book focus on changes in NASA policies that would directly reduce or eliminate the cost growth of Earth and space science missions. Large cost growth is a concern for Earth and space science missions, and it can be a concern for other missions as well. If the cost growth is large enough, it can create liquidity problems for NASA's Science Mission Directorate that in turn cause cost profile changes and development delays that amplify the overall cost growth for other concurrent and/or pending missions. Addressing cost growth through the allocation of artificially high reserves is an inefficient use of resources because it unnecessarily diminishes the portfolio of planned flights. The most efficient use of resources is to establish realistic budgets and reserves and effective management processes that maximize the likelihood that mission costs will not exceed reserves. NASA is already taking action to reduce cost growth; additional steps, as recommended herein, will help improve NASA's mission planning process and achieve the goal of ensuring frequent mission opportunities for NASA Earth and space science."--Publisher's description. 606 $aSpace shuttles$xCosts 606 $aSpace sciences$zUnited States$xFinance 606 $aAstronautics$zUnited States$xCosts 615 0$aSpace shuttles$xCosts. 615 0$aSpace sciences$xFinance. 615 0$aAstronautics$xCosts. 676 $a354.79 712 02$aNational Research Council (U.S.).$bSpace Studies Board. 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910791761803321 996 $aControlling cost growth of NASA Earth and Space Science Missions$93833836 997 $aUNINA LEADER 00935nas 2200385 c 450 001 9910895006003321 005 20260218111217.0 035 $a(CKB)3790000000122894 035 $a(DE-599)ZDB2719664-1 035 $a(OCoLC)854725648 035 $a(DE-101)1035677806 035 $a(DE-599)2719664-1 035 $a(EXLCZ)993790000000122894 100 $a20130611b19151918 |y | 101 0 $ager 135 $aur||||||||||| 181 $ctxt$2rdacontent 182 $cc$2rdamedia 183 $acr$2rdacarrier 200 00$aPolen$eWochenschrift für polnische Interessen 210 31$aWien$d1915-1918 215 $aOnline-Ressource 517 $aPolen 608 $aZeitung$2gnd-content 676 $a320 676 $a070 676 $a910 676 $a940 801 0$b0355 801 1$bDE-101 801 2$b9999 906 $aJOURNAL 912 $a9910895006003321 996 $aPolen$91378785 997 $aUNINA
