Real-Time Contrail Monitoring and Mitigation Using CubeSat Constellations (2024)
Journal Article
Pushparaj, N., Cormier, L., Cappelletti, C., & Portapas, V. (2024). Real-Time Contrail Monitoring and Mitigation Using CubeSat Constellations. Atmosphere, 15(12), Article 1543. https://doi.org/10.3390/atmos15121543

Contrails, or condensation trails, left by aircraft, significantly contribute to global warming by trapping heat in the Earth’s atmosphere. Despite their critical role in climate dynamics, the environmental impact of contrails remains underexplored....

Presentation / Conference Contribution
Bonfitto, F., Fayon, G., Gallucci, A., Iorga, M.-B., Nigro, F., Pushparaj, N., Alqattan, Y., Sadhukhan, D., Rümmler, L., & Soulard, N. (2024, October). Roles, effects, and ramifications of in-person interactions in a digital team. Paper presented at 75th International Astronautical Congress, Milan, Italy

The democratisation of Agile and SAFe development approach in the IT sector following the social web deployment in the second half of the 2000's led in parallel to the emergence of the digital transformation concept. In order to ease the collaboratio... Read More about Roles, effects, and ramifications of in-person interactions in a digital team.

Optimization of MMX relative quasi-satellite transfer trajectories using primer vector theory (2024)
Journal Article
Pushparaj, N., Baresi, N., & Kawakatsu, Y. (2024). Optimization of MMX relative quasi-satellite transfer trajectories using primer vector theory. Acta Astronautica, 225, 390-401. https://doi.org/10.1016/j.actaastro.2024.09.031

Quasi-satellite orbits (QSO) are stable retrograde parking orbits around Phobos that are currently being considered for JAXA’s upcoming robotic sample return mission Maritan Moons Exploration (MMX). During the proximity operations o... Read More about Optimization of MMX relative quasi-satellite transfer trajectories using primer vector theory.

Quasi-solar Synchronous Orbit around the Moon based on Spatial Distant Retrograde Orbits (2023)
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.

Breaking the Cycle: Novel Capture Mechanisms for Active Space Debris Removal (2023)
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.

Optimal Transfer Trajectories between Relative Quasi-Satellite Orbits (2023)
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

In recent years, there has been growing interest in space exploration, particularly in exploring the Martian system. The moons Phobos and Deimos of Mars may hold the key to understanding how the Solar system formed. As a result, space agencies like N...
