Introduction to Aerospace Engineering: Astronautics and Human Spaceflight

4.9

Spaceflight is exciting, and you don’t have to be a “Rocket Scientist” to share in the excitement! 16.00x makes the basics of spaceflight accessible to everyone. Join MIT Professor Jeffrey Hoffman, a former NASA astronaut who made five spaceflights and was the first astronaut to log 1000 hours on the Space Shuttle, as he teaches you the core principles behind space travel and exploration. The course will cover how rockets work, how spacecraft move in orbit, how we create artificial environments inside spacecraft to keep astronauts alive and healthy, what it’s like living in a world without gravity, how the human body adapts to space, and how spacewalks happen, plus more. Many lessons will be illustrated with Professor Hoffman’s own experiences in space.

Class Central TipsLearn How to Sign up to Coursera courses for free1600+ Coursera Courses That Are Still Completely FreeThis course trains you in the skills needed to program specific orientation and achieve precise aiming goals for spacecraft moving through three dimensional space. First, we cover stability definitions of nonlinear dynamical systems, covering the difference between local and global stability. We then analyze and apply Lyapunov's Direct Method to prove these stability properties, and develop a nonlinear 3-axis attitude pointing control law using Lyapunov theory.

Class Central TipsLearn How to Sign up to Coursera courses for free1600+ Coursera Courses That Are Still Completely FreeSpacecraft Dynamics and Control covers three core topic areas: the description of the motion and rates of motion of rigid bodies (Kinematics), developing the equations of motion that prediction the movement of rigid bodies taking into account mass, torque, and inertia (Kinetics), and finally non-linear controls to program specific orientations and achieve precise aiming goals in three-dimensional space (Control). The specialization invites learners to develop competency in these three areas through targeted content delivery, continuous concept reinforcement, and project applications.The goal of the specialization is to introduce the theories related to spacecraft dynamics and control. This includes the three-dimensional description of orientation, creating the dynamical rotation models, as well as the feedback control development to achieve desired attitude trajectories.

For 30 years the Space Shuttle enabled human spaceflight in the United States and partner nations. Learn all about the Shuttle with thisunique course, which also serves as a unique historical record. Since the lecturers are the same people who designed, built and operated the Shuttle, this is a first-hand testimonial to the world’s first reusable spacecraft.This course examines how the Space Shuttle was designed and how its design was influenced by economics and politics. The course goes into detail on many of the Shuttle’s subsystems (e.g. rocket engines, thermal protection, aerodynamics, environmental control and life support, communications, etc.) and explains how the Shuttle was operated (launch, mission control, payloads, etc.). The course also uses the Space Shuttle to present the fundamentals of Systems Engineering.Students will gain a systems perspective on the complexities of Shuttle development and its operations. Itexplores both the Shuttle’s successes and its shortcomings and has valuable object lessons for future space initiatives.The Shuttle is a valuable case study in the advantages and difficulties involved in reusable space systems - particularly relevant today as reusability is a key requirement of many rockets and spacecraft currently under development.In addition, understanding how the Shuttle was first conceived and how it achieved governmental approval is relevant for understanding how politics and economics interact with technology on all large public programs.The lectures are organized in three fundamental sections: history and policy, technical design of Shuttle systems, and how the Shuttle was operated. Although the sections relate to one another, students can benefit from any of the sections independently.This course does not require advanced mathematics.It is targeted to students with a variety of interests including the history of human spaceflight,space policy, the design of human spaceflight systems, the operation of complex space systems, and principles of systems engineering.Image courtesy of NASA: https://www.nasa.gov/sites/default/files/thumbnails/image/739339main_space_shuttle_challenger_04-04-1983.jpg---Please note: edX Inc. has recently entered into an agreement to transfer the edX platform to 2U, Inc., which will continue to run the platform thereafter.

Spacecraft Dynamics Capstone: Mars Mission

Class Central TipsLearn How to Sign up to Coursera courses for free1600+ Coursera Courses That Are Still Completely FreeThe goal of this capstone spacecraft dynamics project is to employ the skills developed in the rigid body Kinematics, Kinetics and Control courses.An exciting two-spacecraft mission to Mars is considered where a primary mother craft is in communication with a daughter vehicle in another orbit.The challenges include determining the kinematics of the orbit frame and several desired reference frames, numerically simulating the attitude dynamics of the spacecraft in orbit, and implementing a feedback control that then drives different spacecraft body frames to a range of mission modes including sun pointing for power generation, nadir pointing for science gathering, mother spacecraft pointing for communication and data transfer.Finally, an integrated mission simulation is developed that implements these attitude modes and explores the resulting autonomous closed-loop performance. Tasks 1 and 2 use three-dimensional kinematics to create the mission related orbit simulation and the associated orbit frames.The introductory step ensures the satellite is undergoing the correct motion, and that the orbit frame orientation relative to the planet is being properly evaluated.Tasks 3 through 5 create the required attitude reference frame for the three attitude pointing modes called sun-pointing, nadir-pointing and GMO-pointing.The reference attitude frame is a critical component to ensure the feedback control drives the satellite to the desired orientation.The control employed remains the same for all three pointing modes, but the performance is different because different attitude reference frames are employed.Tasks 6 through 7 create simulation routines to first evaluate the attitude tracking error between a body-fixed frame and a particular reference frame of the current attitude mode.Next the inertial attitude dynamics is evaluated through a numerical simulation to be able to numerically analyze the control performance.Tasks 8-11 simulate the closed-loop attitude performance for the three attitude modes.Tasks 8 through 10 first simulate a single attitude at a time, while tasks 11 develops a comprehensive attitude mission simulation which considers the attitude modes switching autonomously as a function of the spacecraft location relative to the planet.
