Final Thoughts:
When we think of sailing, it tends to be associated with an image of a recreational getaway.  But sailing may also be the next step towards advancements in space technology and exploration.  In 2015, NASA plans to launch a mission named "Sunjammer".  It will the first solar sail that can be navigated and will also be the world's largest (NASA).  Using ideas adopted from traditional sailing, they plan to use light particles in a similar manner as done with wind.  The light particles will exerts a small force on the reflective solar sail, propelling it through space.  Though the force is small, it is a constant force that will continually accelerate the satellite of a longer time to reach higher speeds with ease.
