This is about my recerch. Would someone correct mistake of grammar?

Laser-Ablation Propulsion

・Background
Laser propulsion has advantages when compared with existing propulsion methods which have to board their propellant, because energy for propulsion is sent by laser beam remotely. It is expected that remote impulse generation enables space debris re-entry and remote satellite altitude correction.

・Object
Recently, space debris coming from retired satellites or the upper stage of rockets has been increasing with the growth of space exploration, and it is becoming a problem for safety. One of the promising solutions for this problem is re-entry by laser-ablation. When a high power laser strikes space debris on the low-Earth-orbit, impulse is generated by ablation jet. Debris can be decelerated by this impulse, and re-enter to the atmosphere. In this laboratory, we research the impulse characteristics that determineby the condition of laser or surface of target.

・Research
We measure the impulse generated by laser ablation by micro-impulse stand using pendulum, and research its impulse characteristics.
