The Advanced Astrodynamics Concepts (AAC) research group is led by Professor James M. Longuski  and Professor Sarag Saikia in the School of Aeronautics and Astronautics, Purdue University. The research group concentrates on spacecraft and mission design concepts that may advance both robotic and human exploration of the Solar System in the next decades.

 Some of the ongoing research projects include the following:

  • Mission architecture to establish permanent human presence on Mars.
  • Aerocapture techniques, concepts, and technology forecasting.
  • Mission concepts for the exploration of small solar system bodies (minor planets, asteroids, comets, KBOs etc.).
  • Rapid conceptual planetary science mission design.
  • Design of planetary atmospheric probes for the exploration of the gas giant planets.
  • Innovative and low-cost planetary exploration missions concepts using small satellites.
  • Systems and technologies for Venus In Situ Missions.
  • Development of analytical planetary entry theories for conceptual design and on-board guidance.
  • Mission concept formulation for the exploration of the Ice-Giant planets, Uranus and Neptune. Includes trajectory design; entry, descent, and landing, and their interaction with science objectives.
  • Design of aerogravity assist missions.
  • Analytic theory of spacecraft attitude dynamics and control.
  • Deep space radiation mitigation using an Ultra-Massive Mars Cycler.
