| Outline of Final Research Achievements |
In this study, we demonstrated the feasibility of the laser ablation propulsion using magnetic fluid as a propellant. First, we verify if the magnetic fluid can be ablated experimentally. The surface shape of the magnetic fluid did not changed after the ablation. Secondly, we observed the splash during the ablation using a high-power laser. The result shows that the droplet generated by the ablation can be returned to the remaining propellant because it was attracted by the magnetic force.
