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.

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!

Frequently asked questions
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
The course may not offer an audit option. 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.
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. If you only want to read and view the course content, you can audit the course for free.
