Why Are Solar Sails Not Currently Being Used as a Means of Propulsion in Space Travel?
Despite their potential benefits, solar sails are not currently being used as a primary means of propulsion in space travel due to several challenges:
- Low thrust: Solar sails rely on the momentum of photons from sunlight, which provides relatively low thrust compared to traditional propulsion systems like chemical rockets.
- Limited range: Solar sails are effective only in regions with substantial sunlight, limiting their range and making them impractical for long-distance missions beyond the inner solar system.
- Susceptibility to space weather: The performance of solar sails can be affected by fluctuations in solar activity, such as solar flares and coronal mass ejections.
- High cost and complexity: Developing and deploying large-scale solar sails is expensive and requires advanced engineering capabilities.
- Long travel times: Due to their low thrust, solar sails take significantly longer to reach their destinations compared to other propulsion systems.
