This book was released on 2014-08-21 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The last several decades have resulted in an unfortunate byproduct of space exploration and development: orbital debris. Satellites in Low Earth Orbit have been required to make an ever increasing number of course corrections in order to avoid collisions. Despite efforts to the contrary, collisions continue to occur, each time creating additional debris and increasing the requirement for the remaining satellites to maneuver. Every required maneuver decreases a satellite's service life. The purpose of this study is to develop a minimum thrust profile to maneuver an orbiting satellite out of its projected error ellipse before a collision occurs. For comparison, both the impulsive and continuous thrust cases were considered as well as in-plane versus out-of plane maneuvering. This study made use of the Radau Pseudospectral Method to develop this minimum thrust profile. This method was run in MATLAB(r) using General Pseudospectral Optimal Control Software (GPOPS-II). Once the optimal solution was obtained, Systems Tool Kit(r) was used to simulate the resulting calculated trajectories and confirm avoidance of the error ellipse.

This book was released on 2011-11-16 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Derelict satellites, equipment and other debris orbiting Earth (aka space junk) have been accumulating for many decades and could damage or even possibly destroy satellites and human spacecraft if they collide. During the past 50 years, various National Aeronautics and Space Administration (NASA) communities have contributed significantly to maturing meteoroid and orbital debris (MMOD) programs to their current state. Satellites have been redesigned to protect critical components from MMOD damage by moving critical components from exterior surfaces to deep inside a satellite's structure. Orbits are monitored and altered to minimize the risk of collision with tracked orbital debris. MMOD shielding added to the International Space Station (ISS) protects critical components and astronauts from potentially catastrophic damage that might result from smaller, untracked debris and meteoroid impacts. Limiting Future Collision Risk to Spacecraft: An Assessment of NASA's Meteoroid and Orbital Debris Program examines NASA's efforts to understand the meteoroid and orbital debris environment, identifies what NASA is and is not doing to mitigate the risks posed by this threat, and makes recommendations as to how they can improve their programs. While the report identified many positive aspects of NASA's MMOD programs and efforts including responsible use of resources, it recommends that the agency develop a formal strategic plan that provides the basis for prioritizing the allocation of funds and effort over various MMOD program needs. Other necessary steps include improvements in long-term modeling, better measurements, more regular updates of the debris environmental models, and other actions to better characterize the long-term evolution of the debris environment.

This book was released on 1998-01-09 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The space shuttle orbiter has already been struck many times by small meteoroids and orbital debris, but it has not been damaged severely. There is a real risk, however, that a meteoroid or debris impact could one day force the crew to abort a mission or might result in loss of life or loss of the shuttle itself. Protecting the Space Shuttle from Meteoroids and Orbital Debris assesses the magnitude of the problem and suggests changes that the National Aeronautics and Space Administration can make to reduce the risk to the shuttle and its crew.

Download or read book Spacecraft Collision Probability written by F. Kenneth Chan and published by . This book was released on 2008 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: The amount of space debris is growing at an alarming rate, raising concern about its collision with operational spacecraft. This book analyzes the probability of such a collision when the orbits of two approaching objects are based on measurements with inherent errors. Many recent papers have dealt with the methodology of computing the collision probability in the encounter region, but they have assumed that the encounter is a flyby and is short-term, with the trajectories of the objects represented by straight lines. By contrast, Spacecraft Collision Probability, the outgrowth of the authors research during the past two decades, deals not only with those cases but also with important long-term cases in which objects spend protracted periods in the vicinity of each other. An extensive chapter is included on the International Space Station (ISS), to demonstrate how one would accurately gauge its probability of collision. The ISS is modeled according to its actual complex shape, component by componentenabling the detailed computation of a more realistic collision probability than one would obtain by the routine practice of modeling it as a sphere. In addition, the author developed Excel macros to obtain the numerical tables and graphical plots appearing in the book. That software is available on the Supporting Materials page of the AIAA Web site.
Download or read book Preventing Collisions Sea written by John (Jack) Herther and published by . This book was released on 2021-01-23 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: A collision at sea can ruin your entire day! Roughly ninety percent of the world's goods are transported by sea with over seventy percent as containerized cargo. Furthermore, just 15 of the biggest ships may now emit as much pollution as all the world's 760 million cars. That is why it is urgent to stop collisions @sea and save fuel. Making ships safer and more fuel-efficient is vital to our nation and fighting climate change.My mission was to prevent oil spills from destroying our environment. To prevent oily birds and beaches ruined by oil. The book describes many collisions at sea and devastating groundings. It explains WHY ships collide and run aground and why Radar is not the answer.There have been dozens of major of ship collisions spilling over 2.7 Million tonnes of oil devastating our environment. The EXXON Valdez alone cost the environment and ultimately taxpayers $5 Billion of environmental cleanup. The more recent Navy ship collisions and disasters killed 17 sailors, costs billions in ship repair but more tragically brought out the incompetence of high-level Navy Officers through a series of firings and resignations.My company developed the world's first fully automatic radar plotter for merchant ship collision avoidance. Iotron pioneered not only "hands-off" anti-collision self-plotting radar, which was installed on 550 large ships proven effective with over 60 million hours at sea. It was installed on 34 Super Tankers, 20 of which had fuel saving autopilots to help eliminate CO2 and dramatically mitigate climate change. Had DigiPLOT been aboard the Torrey Canyon, Costa Concordia and the Esso Valdez, these names would not have their NAMES NOTED for their infamous accidents.The seven tragic Navy collisions would not have been sad news.This book covers the politics of the inept IMO as well as Navy incompetence and inaction that is terrifying. It's time for the US to act and the book describes how they can merely redo their 1978 laws for a Marad Collision Avoidance System specification.Entrepreneurs and Want-to-be entrepreneurs will be inspired to read the Chapter on lessons on Entrepreneurship and starting companies.
