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.

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.

Frequent Deep-Space Access Strategy for Venus Aeronomic Exploration Mission using Earth-Synchronous Orbits (2023)
Conference Proceeding
Ito, D., Pushparaj, N., & Kawakatsu, Y. (2023). Frequent Deep-Space Access Strategy for Venus Aeronomic Exploration Mission using Earth-Synchronous Orbits.

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 (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.

Do Look Up: A young generation's perspective on Planetary Defense (2022)
Conference Proceeding
Gloder, A., Cader, S., Austen, E., Choudhary, M., Garcia-Bonilla, J., Vizireanu, A., …Sarli, B. (2022). Do Look Up: A young generation's perspective on Planetary Defense.

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...
