Return the clock angle to 0 degrees. Set the cone angle to 35 degrees.
Type “m” to go to map mode. Zoom out and rotate the camera until you’re looking on top of the solar system.
Click the “Show Preview” button. Now, click on the “+10” button under the “Days” column. Notice how the red line grows. This is your final orbit after sailing. A smaller yellow line shows the path your sail will take during the number of days shown. The orbit grows because the reflected sunlight bounces off the sail and produces thrust like rocket exhaust in a direction that’s with the orbit velocity.
Set the cone angle to -35 degrees. Notice how the final (red) orbit is now smaller. Negative cone angles let you tack a solar sail closer to the sun. The reflected sunlight acts like rocket exhaust. When it shines against orbital velocity, it will slow the spacecraft down and shrink the orbit.
Set the cone angle to 35 degrees, and the clock angle to 90 degrees. Rotate the view so you’re looking at the orbit from the side. Increase the number of days of the maneuver and observe how the orbit tilts. Clock angle generates out-of-plane thrust that changes the orbit inclination.
