EARLY DRAFT - NASAWATCH.COM/SPACEREF.COM Preface Patrick Besha, Editor Alexander MacDonald, Editor In the next decade, NASA will seek to expand humanity’s presence in space beyond the International Space Station in low-Earth orbit to a new habitation platform orbiting the moon. By the late 2020’s, astronauts will live and work far deeper in space than ever before. The push to cis-lunar orbit is part of a stepping-stone approach to extend our reach to Mars and beyond. This decision to explore ever farther destinations is a familiar pattern in the history of American space exploration. Another major pattern with historical precedent is the transition from public sector exploration to private sector commercialization. After the government has developed and demonstrated a capability in space, whether it be space-based communications or remote sensing, the private sector has realized its market potential. As new companies establish a presence, the government withdraws from the market. In 2015, we are once again at a critical stage in the development of space. The most successful long-term human habitation in space, orbiting the Earth continuously since 1998, is the International Space Station. Currently at the apex of its capabilities and the pinnacle of state-of-the-art space systems, it was developed through the investments and labors of over a dozen nations and is regularly re-supplied by cargo delivery services. Its occupants include six astronauts and numerous other organisms from Earth’s ecosystems from bacteria to plants to rats. Research is conducted on the spacecraft from hundreds of organizations worldwide ranging from academic institutions to large industrial companies and from high-tech start-ups to high-school science classes. -

Congress of the United States Congressional Budget Office May 1988
CONGRESS OF THE UNITED STATES CONGRESSIONAL BUDGET OFFICE MAY 1988 A SPECIAL STUDY THE NASA PROGRAM IN THE 1990s AND BEYOND The Congress of the United States Congresssional Budget Of'f'ice NOTES All costs are expressed in 1988 dollars of budget authority, unless otherwise noted. All years are fiscal years, except when applied to launch schedules. PREFACE The United States space program stands at a crossroads. The momentum of the National Aeronautics and Space Administration (NASA) program over the last 20 years has brought NASA to a point where new activities will require substantial increases in the agency's budget. Critics of the NASA program have called for even more ambi- tious goals, most prominently an expansion of manned space flight to the Moon or Mars. Fiscal concerns, however, may limit even the more modest set of activities envisioned by NASA. This special study, requested by the Senate Committee on Commerce, Science, and Trans- portation, examines the broad options for the U.S. space program in the 1990s. In keeping with the mandate of the Congressional Budget Office (CBO) to provide objective nonpartisan analysis, the report makes no recommendations. David H. Moore, of CBO's Natural Resources and Commerce Division, prepared the report under the supervision of Everett M. Ehrlich. Frances M. Lussier of CBO's National Security Division and Michael Sieverts of CBO's Budget Analysis Division provided valu- able comments and assistance. Many outside reviewers made useful comments and criticisms. Amanda Balestrieri edited the manuscript. Margaret Cromartie prepared early drafts of the report, and Kathryn Quattrone prepared the final draft for publication. -
Can There Be Additional Rocky Planets in the Habitable Zone of Tight Binary
Mon. Not. R. Astron. Soc. 000, 1–10 () Printed 24 September 2018 (MN LATEX style file v2.2) Can there be additional rocky planets in the Habitable Zone of tight binary stars with a known gas giant? B. Funk1⋆, E. Pilat-Lohinger1 and S. Eggl2 1Institute for Astronomy, University of Vienna, Vienna, Austria 2IMCCE, Observatoire de Paris, Paris, France ABSTRACT Locating planets in Habitable Zones (HZs) around other stars is a growing field in contem- porary astronomy. Since a large percentage of all G-M stars in the solar neighborhood are expected to be part of binary or multiple stellar systems, investigations of whether habitable planets are likely to be discovered in such environments are of prime interest to the scientific community. As current exoplanet statistics predicts that the chances are higher to find new worlds in systems that are already known to have planets, we examine four known extrasolar planetary systems in tight binaries in order to determine their capacity to host additional hab- itable terrestrial planets. Those systems are Gliese 86, γ Cephei, HD 41004 and HD 196885. In the case of γ Cephei, our results suggest that only the M dwarf companion could host ad- ditional potentially habitable worlds. Neither could we identify stable, potentially habitable regions around HD 196885A. HD 196885 B can be considered a slightly more promising tar- get in the search forEarth-twins.Gliese 86 A turned out to be a very good candidate, assuming that the system’s history has not been excessively violent. For HD 41004 we have identified admissible stable orbits for habitable planets, but those strongly depend on the parameters of the system. -
Space Shuttle Program
Space Shuttle program The Space Shuttle Columbia seconds after engine ignition, 1981 (NASA). For the first two missions only, the external fuel tank spray-on foam insulation (SOFI) was painted white. Subsequent missions have featured an unpainted tank thus exposing the orange/rust colored foam insulation. This resulted in a weight saving of over 1,000 lb (450 kg), a savings that translated directly to added payload capacity to orbit. NASA's Space Shuttle, officially called Space Transportation System (STS), is the United States government's sole manned launch vehicle currently in service. The winged shuttle orbiter is launched vertically, carrying usually five to seven astronauts and up to about 22,700 kg (50,000 lbs) of payload into low earth orbit. When its mission is complete, it reenters the earth's atmosphere and makes an unpowered gliding horizontal landing, usually on a runway at Kennedy Space Center. The Space Shuttle orbiter was manufactured by North American Rockwell, now part of the Boeing Company. Martin Marietta (now part of Lockheed Martin) designed the external fuel tank and Morton Thiokol (now part of Alliant Techsystems (ATK)) designed the solid rocket boosters. The Shuttle is the first orbital spacecraft designed for partial reusability. It carries large payloads to various orbits, provides crew rotation for the International Space Station (ISS), and performs servicing missions. While the vehicle was designed with the capacity to recover satellites and other payloads from orbit and return them to Earth, this capacity has not been used often; it is, however, an important use of the Space Shuttle in the context of the ISS program, as only very small amounts of experimental material, hardware needing to be repaired, and trash can be returned by Soyuz. -
Solar System Exploration: a Vision for the Next Hundred Years
IAC-04-IAA.3.8.1.02 SOLAR SYSTEM EXPLORATION: A VISION FOR THE NEXT HUNDRED YEARS R. L. McNutt, Jr. Johns Hopkins University Applied Physics Laboratory Laurel, Maryland, USA [email protected] ABSTRACT The current challenge of space travel is multi-tiered. It includes continuing the robotic assay of the solar system while pressing the human frontier beyond cislunar space, with Mars as an ob- vious destination. The primary challenge is propulsion. For human voyages beyond Mars (and perhaps to Mars), the refinement of nuclear fission as a power source and propulsive means will likely set the limits to optimal deep space propulsion for the foreseeable future. Costs, driven largely by access to space, continue to stall significant advances for both manned and unmanned missions. While there continues to be a hope that commercialization will lead to lower launch costs, the needed technology, initial capital investments, and markets have con- tinued to fail to materialize. Hence, initial development in deep space will likely remain govern- ment sponsored and driven by scientific goals linked to national prestige and perceived security issues. Against this backdrop, we consider linkage of scientific goals, current efforts, expecta- tions, current technical capabilities, and requirements for the detailed exploration of the solar system and consolidation of off-Earth outposts. Over the next century, distances of 50 AU could be reached by human crews but only if resources are brought to bear by international consortia. INTRODUCTION years hence, if that much3, usually – and rightly – that policy goals and technologies "Where there is no vision the people perish.” will change so radically on longer time scales – Proverbs, 29:181 that further extrapolation must be relegated to the realm of science fiction – or fantasy. -

DUKSUP: A Computer Program for High Thrust Launch Vehicle Trajectory Design & Optimization Spurlock, O.F.I and Williams, C. H.II NASA Glenn Research Center, Cleveland, OH, 44135 From the late 1960’s through 1997, the leadership of NASA’s Intermediate and Large class unmanned expendable launch vehicle projects resided at the NASA Lewis (now Glenn) Research Center (LeRC). One of LeRC’s primary responsibilities --- trajectory design and performance analysis --- was accomplished by an internally-developed analytic three dimensional computer program called DUKSUP. Because of its Calculus of Variations-based optimization routine, this code was generally more capable of finding optimal solutions than its contemporaries. A derivation of optimal control using the Calculus of Variations is summarized including transversality, intermediate, and final conditions. The two point boundary value problem is explained. A brief summary of the code’s operation is provided, including iteration via the Newton-Raphson scheme and integration of variational and motion equations via a 4th order Runge-Kutta scheme. Main subroutines are discussed. The history of the LeRC trajectory design efforts in the early 1960’s is explained within the context of supporting the Centaur upper stage program. How the code was constructed based on the operation of the Atlas/Centaur launch vehicle, the limits of the computers of that era, the limits of the computer programming languages, and the missions it supported are discussed. The vehicles DUKSUP supported (Atlas/Centaur, Titan/Centaur, and Shuttle/Centaur) are briefly described. The types of missions, including Earth orbital and interplanetary, are described. The roles of flight constraints and their impact on launch operations are detailed (such as jettisoning hardware on heating, Range Safety, ground station tracking, and elliptical parking orbits). -
