The "Bug" Heard 'Round the World
ACM SIGSOFT SOFTWAREENGINEERING NOTES, Vol 6 No 5, October 1981 Page 3 THE "BUG" HEARD 'ROUND THE WORLD Discussion of the software problem which delayed the first Shuttle orbital flight JohnR. Garman Cn April 10, 1981, about 20 minutes prior to the scheduled launching of the first flight of America's Space Transportation System, astronauts and technicians attempted to initialize the software system which "backs-up" the quad-redundant primary software system ...... and could not. In fact, there was no possible way, it turns out, that the BFS (Backup Flight Control System) in the fifth onboard computer could have been initialized , Froperly with the PASS (Primary Avionics Software System) already executing in the other four computers. There was a "bug" - a very small, very improbable, very intricate, and very old mistake in the initialization logic of the PASS. It was the type of mistake that gives programmers and managers alike nightmares - and %heoreticians and analysts endless challenge. I% was the kind of mistake that "cannot happen" if one "follows all the rules" of good software design and implementation. It was the kind of mistake that can never be ruled out in the world of real systems development: a world involving hundreds of programmers and analysts, thousands of hours of testing and simulation, and millions of pages of design specifications, implementation schedules, and test plans and reports. Because in that world, software is in fact "soft" - in a large complex real time control system like the Shuttle's avionics system, software is pervasive and, in virtually every case, the last subsystem to stabilize. -

Hall Engineering and Science Directorate JPL D-97058 Foreword Aerocapture has been proposed for several missions over the last couple of decades, and the technologies have matured over time. This study was initiated because the NASA Planetary Science Division (PSD) had not revisited Aerocapture technologies for about a decade and with the upcoming study to send a mission to Uranus/Neptune initiated by the PSD we needed to determine the status of the technologies and assess their readiness for such a mission. -

During the decade from 1989–1998, NASA used two types of launch systems, one consisting of several families of expendable launch vehicles (ELV) and the second consisting of the world’s only partially reusable launch system—the Space Shuttle. A significant challenge NASA faced during the decade was the development of technologies needed to design and implement a new reusable launch system that would prove less expensive than the Shuttle. Although some attempts seemed promising, none succeeded. This chapter addresses most subjects relating to access to space and space transportation. It discusses and describes ELVs, the Space Shuttle in its launch vehicle function, and NASA’s attempts to develop new launch systems. Tables relating to each launch vehicle’s characteristics are included. The other functions of the Space Shuttle—as a scientific laboratory, staging area for repair missions, and a prime element of the Space Station program—are discussed in the next chapter, Human Spaceflight. This chapter also provides a brief review of launch systems in the past decade, an overview of policy relating to launch systems, a summary of the management of NASA’s launch systems programs, and tables of funding data. The Last Decade Reviewed (1979–1988) From 1979 through 1988, NASA used families of ELVs that had seen service during the previous decade. -

Arnaldi et al.: Human Behavior During Spaceflight - Evidence From an Analog Environment Introduction Four years after the launch of Sputnik, the world’s first artificial satellite, Yuri Gagarin became the first human to reach space (National Aeronautics and Space Administration [NASA], 2011a). The United States soon followed on the path of manned space exploration with Project Mercury. Although this program began with suborbital flights, manned spacecraft were subsequently launched into orbit around the Earth (NASA, 2012). With President Kennedy setting the goal of landing a man on the moon, NASA focused on short-duration orbital flights as a stepping-stone to lunar missions. -
Magnetoshell Aerocapture: Advances Toward Concept Feasibility
Magnetoshell Aerocapture: Advances Toward Concept Feasibility Charles L. Kelly A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Aeronautics & Astronautics University of Washington 2018 Committee: Uri Shumlak, Chair Justin Little Program Authorized to Offer Degree: Aeronautics & Astronautics c Copyright 2018 Charles L. Kelly University of Washington Abstract Magnetoshell Aerocapture: Advances Toward Concept Feasibility Charles L. Kelly Chair of the Supervisory Committee: Professor Uri Shumlak Aeronautics & Astronautics Magnetoshell Aerocapture (MAC) is a novel technology that proposes to use drag on a dipole plasma in planetary atmospheres as an orbit insertion technique. It aims to augment the benefits of traditional aerocapture by trapping particles over a much larger area than physical structures can reach. This enables aerocapture at higher altitudes, greatly reducing the heat load and dynamic pressure on spacecraft surfaces. The technology is in its early stages of development, and has yet to demonstrate feasibility in an orbit-representative envi- ronment. The lack of a proof-of-concept stems mainly from the unavailability of large-scale, high-velocity test facilities that can accurately simulate the aerocapture environment. In this thesis, several avenues are identified that can bring MAC closer to a successful demonstration of concept feasibility. A custom orbit code that dynamically couples magnetoshell physics with trajectory prop- agation is developed and benchmarked. The code is used to simulate MAC maneuvers for a 60 ton payload at Mars and a 1 ton payload at Neptune, both proposed NASA mis- sions that are not possible with modern flight-ready technology. In both simulations, MAC successfully completes the maneuver and is shown to produce low dynamic pressures and continuously-variable drag characteristics. -

IAC-14,E7,4.2x21779 FROM SPACE TOURISTS TO UNRULY PASSENGERS? THE US STRUGGLE WITH ‘ON-ORBIT JURISDICTION’ Frans G. von der Dunk University of Nebraska-Lincoln, College of Law, Space, Cyber and Telecommunications Law Program [email protected] Abstract With the first proper commercial sub-orbital ‘space tourist’ flights seemingly around the corner, the need to develop a proper legal system addressing all relevant parameters, scenarios and events also arises more visibly. This is particularly true for the United States, where so far the major developments in private manned spaceflight are concentrated, some of which may soon move from relatively straightforward up-and-down sub-orbital trajectories to longer-duration sub- orbital and/or orbital flights, or even long-duration presence in (potentially private) space stations. -

A Pictorial History of Rockets
he mighty space rockets of today are the result A Pictorial Tof more than 2,000 years of invention, experi- mentation, and discovery. First by observation and inspiration and then by methodical research, the History of foundations for modern rocketry were laid. Rockets Building upon the experience of two millennia, new rockets will expand human presence in space back to the Moon and Mars. These new rockets will be versatile. They will support Earth orbital missions, such as the International Space Station, and off- world missions millions of kilometers from home. Already, travel to the stars is possible. Robotic spacecraft are on their way into interstellar space as you read this. Someday, they will be followed by human explorers. Often lost in the shadows of time, early rocket pioneers “pushed the envelope” by creating rocket- propelled devices for land, sea, air, and space. When the scientific principles governing motion were discovered, rockets graduated from toys and novelties to serious devices for commerce, war, travel, and research. This work led to many of the most amazing discoveries of our time. The vignettes that follow provide a small sampling of stories from the history of rockets. They form a rocket time line that includes critical developments and interesting sidelines. In some cases, one story leads to another, and in others, the stories are inter- esting diversions from the path. They portray the inspirations that ultimately led to us taking our first steps into outer space. NASA’s new Space Launch System (SLS), commercial launch systems, and the rockets that follow owe much of their success to the accomplishments presented here. -
The New American Space Age: a Progress Report on Human Spaceflight the New American Space Age: a Progress Report on Human Spaceflight the International Space
The New American Space Age: A PROGRESS REPORT ON HUMAN SpaCEFLIGHT The New American Space Age: A Progress Report on Human Spaceflight The International Space Station: the largest international scientific and engineering achievement in human history. The New American Space Age: A Progress Report on Human Spaceflight Lately, it seems the public cannot get enough of space! The recent hit movie “Gravity” not only won 7 Academy Awards – it was a runaway box office success, no doubt inspiring young future scientists, engineers and mathematicians just as “2001: A Space Odyssey” did more than 40 years ago. “Cosmos,” a PBS series on the origins of the universe from the 1980s, has been updated to include the latest discoveries – and funded by a major television network in primetime. And let’s not forget the terrific online videos of science experiments from former International Space Station Commander Chris Hadfield that were viewed by millions of people online. Clearly, the American public is eager to carry the torch of space exploration again. Thankfully, NASA and the space industry are building a host of new vehicles that will do just that. American industry is hard at work developing new commercial transportation services to suborbital altitudes and even low Earth orbit. NASA and the space industry are also building vehicles to take astronauts beyond low Earth orbit for the first time since the Apollo program. Meanwhile, in the U.S. National Lab on the space station, unprecedented research in zero-g is paving the way for Earth breakthroughs in genetics, gerontology, new vaccines and much more. -
