Quasi-solar Synchronous Orbit around the Moon based on Spatial Distant Retrograde Orbits (2023)
Conference Proceeding
Peng, L., Liang, Y., Pushparaj, N., & Shi, P. (2023). Quasi-solar Synchronous Orbit around the Moon based on Spatial Distant Retrograde Orbits.

The last several decades have witnessed the rapid development of lunar exploration, promoting researches on various types of lunar orbits including Distant Retrograde Orbits (abbr. DRO) that are feasible for orbiting tasks due to their stability. Man... Read More about Quasi-solar Synchronous Orbit around the Moon based on Spatial Distant Retrograde Orbits.

Breaking the Cycle: Novel Capture Mechanisms for Active Space Debris Removal (2023)
Conference Proceeding
Taggart, A., Harris, J., Pushparaj, N., & Cappelletti, C. (2023). Breaking the Cycle: Novel Capture Mechanisms for Active Space Debris Removal.

Since the launch of Sputnik 1 in 1957, over 6000 rockets and more than 11,300 satellites have been launched into space, resulting in a high number of artificial space debris in orbit around Earth. Of this debris, there are over one million objects be... Read More about Breaking the Cycle: Novel Capture Mechanisms for Active Space Debris Removal.

Optimal Transfer Trajectories between Relative Quasi-Satellite Orbits (2023)
Conference Proceeding
Pushparaj, N., Hiraiwa, N., & Bando, M. (2023). Optimal Transfer Trajectories between Relative Quasi-Satellite Orbits.

Quasi-satellite orbits (QSOs) are stable retrograde orbits in the restricted three-body problem that have gained attention as a viable candidate for future deep-space missions towards remote planetary satellites. Several mission design proposal uses... Read More about Optimal Transfer Trajectories between Relative Quasi-Satellite Orbits.

Stabilization of Spacecraft in Spatial Periodic Orbits using Linear Quadratic Regulator (LQR) (2023)
Presentation / Conference
Pushparaj, N., Hayashi, Y., & Bando, M. (2023, June). Stabilization of Spacecraft in Spatial Periodic Orbits using Linear Quadratic Regulator (LQR). Paper presented at 34th International Symposium on Space Technology and Science & 12th Nano-Satellite Symposium, Kurume, Fukuoka, Japan

Mission design for exploring minor celestial bodies and planetary satellites presents significant technical challenges, particularly in highly perturbed dynamical environments. The weak and complex gravitational fields of small bodies, along with per... Read More about Stabilization of Spacecraft in Spatial Periodic Orbits using Linear Quadratic Regulator (LQR).
