WEAK STABILITY BOUNDARY TRANSFERS TO MOON AND MARS by Pooja Dutt Pdf

The conventional method to design an interplanetary trajectory is by using patched conic technique in two-body problem. It mainly consists of two impulses namely, trans-planetary injection (VTPI) to send the spacecraft from an Earth Parking Orbit (EPO) into heliocentric trajectory towards the destination planet, and Planetary Orbit Insertion (VPOI) to put the spacecraft from a heliocentric trajectory to an orbit around the destination planet. Low-energy transfers are non-conventional methods for interplanetary transfers, and are associated with low-energy with respect to the given major body. Weak Stability Boundary (WSB) transfers, belong to the category of low-energy transfers which take advantage of WSB regions where gravitational attractions of the influencing bodies tend to balance each other, to reduce VPOI (to almost zero in case of lunar transfers). The benefits of using WSB transfer over the conventional transfers are less fuel requirement, more flexibility in arrival orbits, extended launch periods and relaxed operational timeline (Parker and Anderson, 2013). WSB transfer has a major disadvantage of long flight duration. WSB transfer to Moon was first discovered by Belbruno for the Lunar Get-a-Way Special (LGAS) spacecraft which was proposed to use electric propulsion to reach Moon and search for water at its polar regions (Belbruno, 1987). The spacecrafts thrusters were too weak to perform a conventional capture manoeuvre at Moon, so Belbruno proposed an alternative trajectory which would slowly spiral out from Earth, coast to the WSB region so that the spacecraft would be captured into an orbit around Moon. Then it would use its thrusters to spiral down to the final orbit at Moon. WSB is described by Belbruno and Miller (1993) as "a generalization of Lagrange points and a complicated region surrounding the Moon"; Belbruno (2004) as "a region in phase space supporting a special type of chaotic motion for special choices of elliptic initial conditions with respect to m2"; Yagasaki (2004) as "a transition region between the gravitational capture and escape from the Moon in the phase space".

Fly Me to the Moon by Edward Belbruno Pdf

When a leaf falls on a windy day, it drifts and tumbles, tossed every which way on the breeze. This is chaos in action. In Fly Me to the Moon, Edward Belbruno shows how to harness the same principle for low-fuel space travel--or, as he puts it, "surfing the gravitational field." Belbruno devised one of the most exciting concepts now being used in space flight, that of swinging through the cosmos on the subtle fluctuations of the planets' gravitational pulls. His idea was met with skepticism until 1991, when he used it to get a stray Japanese satellite back on course to the Moon. The successful rescue represented the first application of chaos to space travel and ushered in an emerging new field. Part memoir, part scientific adventure story, Fly Me to the Moon gives a gripping insider's account of that mission and of Belbruno's personal struggles with the science establishment. Along the way, Belbruno introduces readers to recent breathtaking advances in American space exploration. He discusses ways to capture and redirect asteroids; presents new research on the origin of the Moon; weighs in on discoveries like 2003 UB313 (now named Eris), a dwarf planet detected in the far outer reaches of our solar system--and much more. Grounded in Belbruno's own rigorous theoretical research but written for a general audience, Fly Me to the Moon is for anybody who has ever felt moved by the spirit of discovery.

The Earth-Moon System as a Dynamical Laboratory by Elisa Maria Alessi,Josep Masdemont,Alessandro Rossi Pdf

The Earth-Moon neighborhood is the scene of a large variety of applications that concern asteroids, lunar exploration and space debris in Earth orbit. In particular, recent efforts by the scientific community have focused on the possibility of extending the human operations beyond the radiation belts; of exploiting in-situ resources, either on the lunar surface or on asteroids retrieved to the vicinity of the Earth; and of mitigating the space debris concern by taking advantage of the lunar perturbation. The characteristic dynamics in the cislunar space represents an opportunity for the mission designer, but also a challenge in terms of theoretical understanding and operational control. This Research Topic covers the Earth-Moon dynamics in its complexity and allure, considering the most relevant aspects for both natural and artificial objects, in order to get a new comprehension of the dynamics at stake along with the operational procedures that can handle it.

Equilibrium, Markets and Dynamics by Cars H. Hommes,Roald Ramer,Cees A. Withagen Pdf

This book contains essays in honour of Claus Weddepohl who, after 22 years, is retiring as professor of mathematical economics at the Department of Quantitative Economics of the University of Amsterdam. Claus Weddepohl may be viewed as th~ first Dutch mathematical economist in the general equi librium tradition of Arrow, Debreu and Hahn. The essays in this book are centered around the themes Equilibrium, Markets and Dynamics, that have been at the heart of Weddepohl's work on mathematical economics for more than three decades. The essays have been classified according to these three themes. Admittedly such a classification always is somewhat arbitrary, and most essays would in fact fit into two or even all three themes. The essays have been written by international as well as Dutch friends and colleagues including Weddepohl's former Ph. D. students. The book starts with a review of Claus Weddepohl's work by Roald Ramer, who has been working with him in Amsterdam for all those years. The review describes how Weddepohl became fascinated by general equilibrium theory in the early stages of his career, how he has been working on the theory of markets throughout his career, and how he turned to applications of nonlinear dynamics to price adjustment processes in a later stage of his career. The first part of the book, Equilibrium, collects essays with general equilib rium theory as the main theme.

Space Manifold Dynamics by Ettore Perozzi,Sylvio Ferraz-Mello Pdf

This book presents an overview of the outcomes resulting from applying the dynamical systems approach to space mission design, a topic referred to as "Space Manifold Dynamics" (SMD). It is a natural follow-on to the international workshop "Novel Spaceways for Scientific and Exploration Missions," which was held in October 2007 at the Telespazio Fucino Space Centre (Italy) under the auspices of the Space OPS Academy. The benefits and drawbacks of using the Lagrangian points and the associated trajectories for present and future space missions are discussed. The related methods and algorithms are also described in detail. Each topic is presented in articles that were written as far as possible to be self consistent; the use of introductory sections and of extended explanations is included in order to address the different communities potentially interested in SMD: space science, the aerospace industry, manned and unmanned exploration, celestial mechanics, and flight dynamics.
