$ASTI The sun’s photons as a propulsion force
With the solar sail, the propulsion force of spacecraft is the sun, as the name suggests. Other names that have been given to the solar sail propulsion technology include ‘light sail’ and ‘photon sail’. The technology works by using the photons that the sun is constantly emitting. These photons do not possess any mass, but this is compensated for by the fact that they have some momentum. When these photons hit the solar sail, they are reflected back and in the process, they push the solar sail in the reverse direction. This momentum builds over time and scientists estimate that speeds of 150,000 mph could be reached in three years making it possible to reach Pluto in under five years.
