Do Look Up: A young generation's perspective on Planetary Defense
Presentation / Conference Contribution
Gloder, A., Cader, S., Austen, E., Choudhary, M., Garcia-Bonilla, J., Vizireanu, A., Hameed, H., Rojas Ramirez, M. E., Pushparaj, N., & Sarli, B. (2022, September). Do Look Up: A young generation's perspective on Planetary Defense. Presented at 73rd International Astronautical Congress (IAC), Paris, France

One aspect of human behaviour that recent events have shown is people's lack of response to seemingly distant or unlikely situations. Nonetheless, this action, or absence of action, results in inadequate planning and policies to deal with high-impact...

Stabilization of Spacecraft in Spatial Periodic Orbits using Linear Quadratic Regulator (LQR)
Presentation / Conference Contribution
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).

Breaking the Cycle: Novel Capture Mechanisms for Active Space Debris Removal
Presentation / Conference Contribution
Taggart, A., Harris, J., Pushparaj, N., & Cappelletti, C. (2023, October). Breaking the Cycle: Novel Capture Mechanisms for Active Space Debris Removal. Presented at 74th International Astronautical Congress. Symposium A6. 21st IAA SYMPOSIUM ON SPACE DEBRIS, Baku, Azerbaijan

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.

Frequent Deep-Space Access Strategy for Venus Aeronomic Exploration Mission using Earth-Synchronous Orbits
Presentation / Conference Contribution
Ito, D., Pushparaj, N., & Kawakatsu, Y. (2023, October). Frequent Deep-Space Access Strategy for Venus Aeronomic Exploration Mission using Earth-Synchronous Orbits. Presented at 74th International Astronautical Congress. Symposium B4. 30th IAA SYMPOSIUM ON SMALL SATELLITE MISSIONS, Baku, Azerbaijan

Geostationary transfer orbits (GTO) are earth-centric orbits widely used for kick-stage operations of satellites for deep space exploration missions. A rideshare spacecraft parked or deployed in GTOs usually requires minimal transfer cost compared to...

Optimal Transfer Trajectories between Relative Quasi-Satellite Orbits
Presentation / Conference Contribution
Pushparaj, N., Hiraiwa, N., & Bando, M. (2023, October). Optimal Transfer Trajectories between Relative Quasi-Satellite Orbits. Presented at 74th International Astronautical Congress, Baku, Azerbaijan

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.

Quasi-solar Synchronous Orbit around the Moon based on Spatial Distant Retrograde Orbits
Presentation / Conference Contribution
Peng, L., Liang, Y., Pushparaj, N., & Shi, P. (2023, October). Quasi-solar Synchronous Orbit around the Moon based on Spatial Distant Retrograde Orbits. Presented at 74th International Astronautical Congress. Symposium A5. 26th IAA SYMPOSIUM ON HUMAN EXPLORATION OF THE SOLAR SYSTEM, Baku, Azerbaijan

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.
