Science as an instrument to justify religious missions in secular society The relationship between religion and science is complex and continues to be a topical issue. However, it is seldom zoomed in on from both Protestant andCatholic perspectives. By doing so the contributing authors in this collection gain new insights into the origin and development of missiology. Missiology is described in this book as a “project of modernity,” a contemporary form of apologetics. “Scientific apologetics” was the way to justify missions in a society that was rapidly becoming secularized. Mission & Sciencedeals with the interaction between new scientific disciplines (historiography, geography, ethnology, anthropology, linguistics) and new scientific insights (Darwin’s evolutionary theory, heliocentrism), as well as the role of the papacy and what inspired missionary practice (first in China and the Far East and later in Africa). The renewed missiology has in turn influenced the missionary practice of the twentieth century, guided by apostolic policy. Some “missionary scholars” have even had a significant influence on the scientific discourse of their time.

"The Tropical Rainfall Measuring Mission (TRMM), a satellite program now being studied jointly by the United States and Japan, would carry out the systematic study of tropical rainfall required for major strides in weather and climate research ... This report presents the scientific justification for TRMM and outlines the implementation process for the scientific community."--Preface.

Principal-investigator (PI) Earth science missions are small, focused science projects involving relatively small spacecraft. The selected PI is responsible for the scientific and programmatic success of the entire project. A particular objective of PI-led missions has been to help develop university-based research capacity. Such missions, however, pose significant challenges that are beyond the capabilities of most universities to manage. To help NASA's Office of Earth Science determine how best to address these, the NRC carried out an assessment of key issues relevant to the success of university-based PI-led Earth observation missions. This report presents the result of that study. In particular, the report provides an analysis of opportunities to enhance such missions and recommendations about whether and, if so, how they should be used to build university-based research capabilities.

NASA's space and Earth science program is composed of two principal components: spaceflight projects and mission-enabling activities. Most of the budget of NASA's Science Mission Directorate (SMD) is applied to spaceflight missions, but NASA identifies nearly one quarter of the SMD budget as "mission enabling." The principal mission-enabling activities, which traditionally encompass much of NASA's research and analysis (R&A) programs, include support for basic research, theory, modeling, and data analysis; suborbital payloads and flights and complementary ground-based programs; advanced technology development; and advanced mission and instrumentation concept studies. While the R&A program is essential to the development and support of NASA's diverse set of space and Earth science missions, defining and articulating an appropriate scale for mission-enabling activities have posed a challenge throughout NASA's history. This volume identifies the appropriate roles for mission-enabling activities and metrics for assessing their effectiveness. Furthermore, the book evaluates how, from a strategic perspective, decisions should be made about balance between mission-related and mission-enabling elements of the overall program as well as balance between various elements within the mission-enabling component. Collectively, these efforts will help SMD to make a good program even better.

Lost in the Stars is a biographical study of Alexander William Roberts, a Free Church of Scotland missionary educator who in 1883 was posted to the Lovedale Institution at Alice, South Africa. Inspired by the night sky of the southern hemisphere, Roberts became a leading observer of variable stars and an early contributor to the theory of close interacting binary stars. He actively promoted the development of colonial scientific culture and was elected president of the South African Association for the Advancement of Science in 1913. His teaching career at Lovedale fostered a commitment to the interests of his African students and their communities. In 1920 Roberts was appointed to the South African senate to represent “native” Africans; he also served as senior member of the Native Affairs Commission. Despite his liberal instincts he acquiesced to the movement toward racial segregation as advanced in the Natives (Urban Areas) and Native Administration Acts. Roberts nonetheless militated against the erosion of the Cape non-racial franchise rights; he resigned from the Native Affairs Commission just as the all-white parliament was poised to remove Africans from the common voters’ roll. His engagement with the politics of race interfered with Roberts’s astronomical research. Although he published nearly one hundred papers in scientific journals most of his observational data remained unknown until the Boyden Observatory’s Roberts archive was digitized in 2006. His influence as a mission educator also has been little known, although among his pupils were journalist and academic D.D.T. Jabavu, the physician James Moroka, and Swazi king Sobhuza I.

Assessment of Mission Size Trade-offs for NASA's Earth and Space Science Missions addresses fundamental issues of mission architecture in the nation's scientific space program and responds to the FY99 Senate conference report, which requested that NASA commission a study to assess the strengths and weaknesses of small, medium, and large missions. This report evaluates the general strengths and weaknesses of small, medium, and large missions in terms of their potential scientific productivity, responsiveness to evolving opportunities, ability to take advantage of technological progress, and other factors that may be identified during the study; identifies which elements of the SSB and NASA science strategies will require medium or large missions to accomplish high-priority science objectives; and recommends general principles or criteria for evaluating the mix of mission sizes in Earth and space science programs. Assessment of Mission Size Trade-offs for NASA's Earth and Space Science Missions considers not only scientific, technological, and cost trade-offs, but also institutional and structural issues pertaining to the vigor of the research community, government-industry university partnerships, graduate student training, and the like.

NASA's Science Mission Directorate (SMD) ties together diverse researchers, sponsors, and resources to develop the science community's understanding of the universe. Within scientific organizations like NASA, it is important to establish clear strategies and goals to guide research and foster new discoveries across varying missions. SMD created a draft for their 2019 Science Plan, and a review of this draft is necessary to ensure that the plan establishes clear, attainable, relevant, and ambitious goals. Review of the Draft 2019 Science Mission Directorate Science Plan provides comments on and recommendations for SMD's draft. Comments in this report focus on the level of ambition of the specified strategies in light of current and emerging opportunities to advance Earth and space science over the next 5 years, the ability of SMD to meet the science objectives in the most recent decadal surveys through implementation of specified strategies, additional strategies for SMD's considerations, and the general readability and clarity of the draft. Recommendations in this report identify important improvements for the 2019 Science Plan.
