When will I have access to the lectures and assignments?

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

What will I get if I subscribe to this Specialization?

When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.

Is financial aid available?

Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.

This is the 3rd and final course of the spacecraft relative motion course sequence. This course presents a capstone design challenge where you get to develop, simulate and study how to approach a tumbling debris object. The servicer starts from far away and carefully does a series of maneuver to get closer and closer in a safe manner. As the debris object is tumbling, the servicer will have to account for relative attitude motion as well. The final approach is in a debris body-fixed manner illustrating a case of controlling non-Keplerian motion.

After this course, you will be able to... * Design safe approach trajectories * Implement relative motion feedback control solutions * Model the relative motion and relative attitude in the LVLH frame * Implement non-Keplerian reference motion Please note: this is an advanced course, best suited for working engineers or students with college-level knowledge in mathematics and physics. The material covered is taking from the book "Analytical Mechanics of Space Systems" available at https://arc.aiaa.org/doi/book/10.2514/4.105210.

Welcome to the capstone project of the course sequence on spacecraft formation flying dynamics and control.

In this module we study how to use a Hohmann transfer to maneuver a servicer spacecraft close to a space debris object. The debris is in a circular orbit with a different radius. Here we study how much fuel such a maneuver will take, the required phasing angle, as well as look at the final maneuver trajectory motion as seen by the chief LVLH frame to determine the smallest miss distance to the debris object.

Here we investigate slowly approaching the debris object. We start with a basic drifting orbit and then look at a safety spiral about the debris object.

Next we are ready to begin our final approach to the debris object. Sadly, the debris object is not holding a steady attitude, but rather it is tumbling. This complicates are final approach as we must control our relative to the debris body-fixed frame to ensure we approach the debris grappling point without colliding in it. What fun!
