- From 25 August–1 October 2025 (6 Weeks, 12 Classes, 24 Hours)
- Every Monday and Wednesday at 4–6 p.m. Eastern Time (all sessions will be recorded and available for replay; course notes will be available for download)
- This course will familiarize students with the essential features of space flight dynamics for various types of space missions and will cover the requirements and design considerations for mission simulation systems.
- Joint course with the International Institute for Astronautical Sciences (IIAS)
- All students will receive a joint AIAA/IIAS Certificate of Completion at the end of the course.
LEARNING OBJECTIVES
Upon completion of the course students will
be able to:
- Explain the relationship of gravity and velocity in establishing suborbital, orbital, and escape trajectories.
- Describe an orbit around a celestial body using classical Keplerian Elements.
- Explain the use of velocity changes to change from an existing to a desired trajectory.
- Demonstrate the use of simplified linearized approximations and their effective use in rendezvous and proximity operations in preparation for docking.
- Describe profiles for establishing departure, rendezvous, encounters, entry, and landings between planets or other celestial bodies.
- Describe vehicle attitude representations and control methods.
- Identify the key elements and considerations for space system simulation design.
- Perform basic flight dynamics modeling using the NASA General Mission Analysis Tool (GMAT) software application.
AUDIENCE: Professionals, graduate students, upper-division undergraduate students.

INSTRUCTOR
Ken has had the privilege of working with numerous space systems including NAVSTAR GPS and the GOES-R series of meteorological satellites, as well as being a member of the Amateur Radio on the International Space Station (ARISS) Inter-Operable Radio System (IORS) development team. For ARISS IORS he is primarily responsible for tracking hardware compliance against the rigid NASA crew safety requirements, coordinating with the design engineers, and preparing the corresponding documentation that is delivered to NASA.
