Targeting a Mars science orbit from Earth using Dual Chemical-Electric Propulsion and Ballistic Capture Jose Angel Gutierrez Ahumada Delft University of Technology TARGETING A MARS SCIENCE ORBIT FROM EARTH USING DUAL CHEMICAL-ELECTRIC PROPULSION AND BALLISTIC CAPTURE by Jose Angel Gutierrez Ahumada MSc Thesis in partial fulfillment of the requirements for the degree of Master of Science in Aerospace Engineering at the Delft University of Technology, to be defended publicly on Wednesday May 8, 2019. Supervisor: Dr. Francesco Topputo, TU Delft/Politecnico di Milano Dr. Ryan Russell, The University of Texas at Austin Thesis committee: Dr. Francesco Topputo, TU Delft/Politecnico di Milano Prof. dr. ir. Pieter N.A.M. Visser, TU Delft ir. Ron Noomen, TU Delft Dr. Angelo Cervone, TU Delft This thesis is confidential and cannot be made public until December 31, 2020. An electronic version of this thesis is available at http://repository.tudelft.nl/. Cover picture adapted from https://steemitimages.com/p/2gs...QbQvi EXECUTIVE SUMMARY Ballistic capture is a relatively novel concept in interplanetary mission design with the potential to make Mars and other targets in the Solar System more accessible. A complete end-to-end interplanetary mission from an Earth-bound orbit to a stable science orbit around Mars (in this case, an areostationary orbit) has been conducted using this concept. Sets of initial conditions leading to ballistic capture are generated for different epochs. The influence of the dynamical model on the capture is also explored briefly. Specific capture trajectories are then selected based on a study of their stabilization into an areostationary orbit. -
Interplanetary Cruising
Interplanetary Cruising 1. Foreword The following material is intended to supplement NASA-JSC's High School Aerospace Scholars (HAS) instructional reading. The author, a retired veteran of 60 Space Shuttle flights at Mission Control's Flight Dynamics Officer (FDO) Console, first served as HAS mentor in association with a June 2008 workshop. On that occasion, he noticed students were generally unfamiliar with the nature and design of spacecraft trajectories facilitating travel between Earth and Mars. Much of the specific trajectory design data appearing herein was developed during that and subsequent workshops as reference material for students integrating it into Mars mission timeline, spacecraft mass, landing site selection, and cost estimates. Interplanetary Cruising is therefore submitted to HAS for student use both before and during Mars or other interplanetary mission planning workshops. Notation in this document distinguishes vectors from scalars using bold characters in a vector's variable name. The "•" operator denotes a scalar product between two vectors. If vectors a and b are represented with scalar coordinates such that a = (a1, a2, a3) and b = (b1, b2, b3) in some 3- dimensional Cartesian system, a • b = a1 b1 + a2 b2 + a3 b3 = a b cos γ, where γ is the angle between a and b. 2. Introduction Material in this reference will help us understand the pedigree and limitations applying to paths (trajectories) followed by spacecraft about the Sun as they "cruise" through interplanetary space. Although cruise between Earth and Mars is used in specific examples, this lesson's physics would apply to travel between any two reasonably isolated objects in our solar system. -

A Delta-V Map of the Known Main Belt Asteroids
Acta Astronautica 146 (2018) 73–82 Contents lists available at ScienceDirect Acta Astronautica journal homepage: www.elsevier.com/locate/actaastro A Delta-V map of the known Main Belt Asteroids Anthony Taylor *, Jonathan C. McDowell, Martin Elvis Harvard-Smithsonian Center for Astrophysics, 60 Garden St., Cambridge, MA, USA ARTICLE INFO ABSTRACT Keywords: With the lowered costs of rocket technology and the commercialization of the space industry, asteroid mining is Asteroid mining becoming both feasible and potentially profitable. Although the first targets for mining will be the most accessible Main belt near Earth objects (NEOs), the Main Belt contains 106 times more material by mass. The large scale expansion of NEO this new asteroid mining industry is contingent on being able to rendezvous with Main Belt asteroids (MBAs), and Delta-v so on the velocity change required of mining spacecraft (delta-v). This paper develops two different flight burn Shoemaker-Helin schemes, both starting from Low Earth Orbit (LEO) and ending with a successful MBA rendezvous. These methods are then applied to the 700,000 asteroids in the Minor Planet Center (MPC) database with well-determined orbits to find low delta-v mining targets among the MBAs. There are 3986 potential MBA targets with a delta- v < 8kmsÀ1, but the distribution is steep and reduces to just 4 with delta-v < 7kms-1. The two burn methods are compared and the orbital parameters of low delta-v MBAs are explored. 1. Introduction [2]. A running tabulation of the accessibility of NEOs is maintained on- line by Lance Benner3 and identifies 65 NEOs with delta-v< 4:5kms-1.A For decades, asteroid mining and exploration has been largely dis- separate database based on intensive numerical trajectory calculations is missed as infeasible and unprofitable. -
Orbital Mechanics of Gravitational Slingshots 1 Introduction 2 Approach
Orbital Mechanics of Gravitational Slingshots Final Paper 15-424: Foundations of Cyber-Physical Systems Adam Moran, [email protected] John Mann, [email protected] May 1, 2016 Abstract A gravitational slingshot is a maneuver to save fuel by using the gravity of a planet to accelerate or decelerate a spacecraft. Due to the large distances and high speeds involved, slingshots require precise accuracy to accomplish | the slightest mistake could cause the whole mission to fail. Therefore, we have developed a cyber-physical system to model the physics and prove the safety and efficiency of powered and unpowered gravitational slingshots. We present our findings and proof in this paper. 1 Introduction A gravitational slingshot is a maneuver performed to increase or decrease the speed of a spacecraft by simply approaching planetary bodies. A spacecraft's usefulness and maneuverability is basically tied to the amount of fuel it can carry, and the more fuel a spacecraft holds, the more fuel it needs to carry that fuel into orbit. Therefore, gravitational slingshots are a very appealing way to save mass, and therefore money, on deep-space missions since these maneuvers do not require any fuel. As missions conducted by national and private space programs become more frequent and ambitious, the need for these precise maneuvers will increase. Therefore, we have created a cyber-physical system that models the physics of a gravitational slingshot for a spacecraft approaching a planet. In the "Approach" section of this paper, we give a brief overview of the physics involved with orbits and gravitational slingshots. In the "Models and Properties" section of this paper, we describe what assumptions and simplifications we made to model these astrophysics in a way for us to prove our desired properties with KeYmaeraX. -

Us Rocket Propulsion Industrial Base Assessment
OMB Control Number: ####-#### Expiration Date: 12/31/2017 U.S. ROCKET PROPULSION INDUSTRIAL BASE ASSESSMENT: Propulsion Survey SCOPE OF ASSESSMENT The U.S. Department of Commerce, Bureau of Industry and Security (BIS), Office of Technology Evaluation (OTE), in coordination with the U.S. National Aeronautics and Space Administration (NASA) and U.S. Department of Defense (DOD) co-chaired Joint Army, Navy, NASA, Air Force Interagency Propulsion Committee (JANNAF) is conducting a survey and assessment of organizations responsible for the research, design, engineering, development, manufacture, testing, and integration of rocket propulsion-related products, components, and services. The principal goal of this assessment is to gain an understanding of the intricate supply chain network supporting the development, production, and sustainment of products and services across both the U.S. Government and commercial propulsion-related sectors. With the data collected in this survey, U.S. Government agencies will be better informed and able to develop targeted planning, acquisition, and investment strategies to ensure industry's ability to support critical defense and civil missions and programs. RESPONSE TO THIS SURVEY IS REQUIRED BY LAW A response to this survey is required by law (50 U.S.C. App. Sec. 2155). Failure to respond can result in a maximum fine of $10,000, imprisonment of up to one year, or both.
