%K LightSail-2, Solar Sailing, Orbital Mechanics, Optimal Attitude Strategy.
%X Planetary Societys LightSail-2 mission successfully validated the orbital maneuvering capability of a Solar Radiation Pressure propelled spacecraft. This paper presents a study on alternative attitude strategies for the orientation of its solar sail with the goal of increasing the spacecrafts orbital maneuverability and its capacity of gaining altitude. Simulations with the use of Planetary Societys published strategy were made and compared with one that keeps the orientation of the solar sail at a direction that maximizes the spacecrafts specific orbital energy gain. A third strategy was proposed, with an additional goal of reducing the number of attitude maneuvers. Results show that it is possible to enhance the altitude gain of the spacecraft and improve the propelling influence of a solar sail while still reducing the number of maneuvers necessary to change the spacecrafts attitude.
