Book Description
Space-based Telescopes for Actionable Refinement of Ephemeris (STARE) is a nano-sat based mission designed to better determine the trajectory of satellites and space debris in orbit around earth. In this paper, we give a brief overview of the mission and its place in the larger context of Space Situational Awareness (SSA). We then describe the details of the central optical payload, touching on the optical design and characterization of the on-board image sensor used in our Cubesat based prototype. Finally, we discuss the on-board star and satellite track detection algorithm central to the success of the mission.

Book Description
This book was compiled from contributions given at the 7th IAA Symposium on Small Satellites for Earth Observation, May 4–8, 2009, Berlin (IAA – International Academy of Astronautics). From the 15 sessions for oral presentations and two poster sessions, 52 contributions were selected which are representative for the new developments and trends in the area of small satellites for Earth observation. They re ect the potentials of a diversity of missions and related technologies. This may be based on national projects or international co-operations, single satellites of constellations, pico-, nano-, micro- or mini-satellites, developed by companies, research institutions or agencies. The main focus is on new missions to monitor our Earth’s resources (Part I), and the environment in which our Earth is emb- ded (Part II). Part III deals with distributed space systems, a unique feature of small satellites and in most cases impractical to do with large satellites. Here we concentrate on constellations of satellites with focus on future missions relying on co-operating satellites. For all the new developments and projects we need well e- cated specialists coming from the universities. Many universities included already the development and implementation of small satellites in their curriculum. The u- versity satellites chapter (Part IV) shows the high quality which is already reached by some of the universities worldwide.

Book Description
This book describes prominent technological achievements within a very successful space science mission: the Herschel space observatory. Focusing on the various processes of innovation it offers an analysis and discussion of the social, technological and scientific context of the mission that paved the way to its development. It addresses the key question raised by these processes in our modern society, i.e.: how knowledge management of innovation set the conditions for inventing the future? In that respect the book is based on a transdisciplinary analysis of the programmatic complexity of Herschel, with inputs from space scientists, managers, philosophers, and engineers. This book is addressed to decision makers, not only in space science, but also in other industries and sciences using or building large machines. It is also addressed to space engineers and scientists as well as students in science and management.

Book Description
In this paper, we introduce the concept of a stare-mode astrometric space mission. The traditionally accepted mode of operation for a mapping astrometric space mission is that of a continuously scanning satellite, such as the successful Hipparcos and planned Gaia missions. With the advent of astrometry missions mapping out stars to 20th magnitude, the stare mode has become competitive. A stare mode of operation has several advantages over a scanning mission if absolute parallax and throughput issues can be successfully addressed. Requirements for a stare-mode operation are outlined here. The mission precision for a stare-mode astrometric mission is derived as a function of instrumental parameters, and examples are given. The stare-mode concept has been accepted as a baseline for the NASA road map study of the Origins Billions Star Survey (OBSS) mission and the proposed Milliarcsecond Pathfinder Survey (MAPS) microsatellite project.

Book Description
The Orbiter Camera Payload System (OCPS) is an integrated photographic system which is carried into earth orbit as a payload in the Space Transportation System (STS) Orbiter vehicle's cargo bay. The major component of the OCPS is a Large Format Camera (LFC), a precision wide-angle cartographic instrument that is capable of producing high resolution stereo photography of great geometric fidelity in multiple base-to-height (B/H) ratios. A secondary, supporting system to the LFC is the Attitude Reference System (ARS), which is a dual lens Stellar Camera Array (SCA) and camera support structure. The SCA is a 70-mm film system which is rigidly mounted to the LFC lens support structure and which, through the simultaneous acquisition of two star fields with each earth-viewing LFC frame, makes it possible to determine precisely the pointing of the LFC optical axis with reference to the earth nadir point. Other components complete the current OCPS configuration as a high precision cartographic data acquisition system. The primary design objective for the OCPS was to maximize system performance characteristics while maintaining a high level of reliability compatible with Shuttle launch conditions and the on-orbit environment. The full-up OCPS configuration was launched on a highly successful maiden voyage aboard the STS Orbiter vehicle Challenger on October 5, 1984, as a major payload aboard mission STS 41-G. This report documents the system design, the ground testing, the flight configuration, and an analysis of the results obtained during the Challenger mission STS 41-G.

Book Description
"Using a solar sail, the Solar Polar Imager mission would observe the Sun from a polar orbit to observe magnetic fields and convective flows in the polar regions as well as coronal mass ejections and the Sun's outer atmosphere in order to better understand the solar dynamo and solar activity. Titan Explorer mission includes an orbiter with remote sensing instruments and an airship platform to investigate the atmosphere, clouds, haze, and surface of Saturn's moon Titan. Neptune Orbiter with Probes mission would use aerocapture to explore Neptune's rings and magnetosphere, which serve as an analog for the primordial solar nebula and accretion disks around other stars, and its satellite Triton, which resembles small objects at the outer boundary of our solar system today. Neptune Orbiter, Probe, and Lander mission would use nuclear electric propulsion to investigate Neptune and orbit its satellite, Triton. Interstellar Probe would leave the heliosphere to explore interstellar space, learning about its composition and dynamics and its interaction with our solar system. Observing distant stars with ultra-high resolution, the Stellar Imager mission could reveal their magnetic activity and internal structure, helping us understand solar activity and magnetohydrodynamics throughout the Universe. By bringing our understanding of other galaxies nearly up to our understanding of our own, the Modern Universe Space Telescope could illuminate how the chemical elements are created and dispersed, how normal galaxies form and evolve, and how stars and planetary systems form. Generation-X mission could detect the first black holes formed when the Universe was only a few hundred million years old. Advanced Compton Telescope is a wide-field gamma-ray spectrometer designed to uncover how supernovae and other stellar explosions create the chemical elements through an all-sky survey of nuclear line emissions. Far-Infrared/Submillimeter Interferometer in Space would use a two-element array to study the formation of the earliest-born stars and galaxies in the Universe and to probe the structure of the disks of gas and dust collapsing today to form a new generation of stars and planets. Single Aperture Far Infrared Observatory would be a single-spacecraft large space telescope for observing the early chemical history of the Universe and the structure of young planetary systems, tracking the chemistry needed for life from interstellar clouds to young solar systems. A final chapter describes an analysis of directions for future technology development inspired by this portfolio of mission concepts."--Publisher description.

Book Description
Space-based observations have transformed our understanding of Earth, its environment, the solar system and the universe at large. During past decades, driven by increasingly advanced science questions, space observatories have become more sophisticated and more complex, with costs often growing to billions of dollars. Although these kinds of ever-more-sophisticated missions will continue into the future, small satellites, ranging in mass between 500 kg to 0.1 kg, are gaining momentum as an additional means to address targeted science questions in a rapid, and possibly more affordable, manner. Within the category of small satellites, CubeSats have emerged as a space-platform defined in terms of (10 cm x 10 cm x 10 cm)- sized cubic units of approximately 1.3 kg each called "U's." Historically, CubeSats were developed as training projects to expose students to the challenges of real-world engineering practices and system design. Yet, their use has rapidly spread within academia, industry, and government agencies both nationally and internationally. In particular, CubeSats have caught the attention of parts of the U.S. space science community, which sees this platform, despite its inherent constraints, as a way to affordably access space and perform unique measurements of scientific value. The first science results from such CubeSats have only recently become available; however, questions remain regarding the scientific potential and technological promise of CubeSats in the future. Achieving Science with CubeSats reviews the current state of the scientific potential and technological promise of CubeSats. This report focuses on the platform's promise to obtain high- priority science data, as defined in recent decadal surveys in astronomy and astrophysics, Earth science and applications from space, planetary science, and solar and space physics (heliophysics); the science priorities identified in the 2014 NASA Science Plan; and the potential for CubeSats to advance biology and microgravity research. It provides a list of sample science goals for CubeSats, many of which address targeted science, often in coordination with other spacecraft, or use "sacrificial," or high-risk, orbits that lead to the demise of the satellite after critical data have been collected. Other goals relate to the use of CubeSats as constellations or swarms deploying tens to hundreds of CubeSats that function as one distributed array of measurements.
