Solar sails (also known as lightsails, light sails, and photon sails) are a method of spacecraft propulsion using radiation pressure exerted by sunlight...

A diffractive solar sail, or diffractive lightsail, is a type of solar sail which relies on diffraction instead of reflection for its propulsion. Current...

LightSail is a project to demonstrate controlled solar sailing within low Earth orbit using a CubeSat. The project was developed by The Planetary Society...

electric sail (also known as an electric solar wind sail or an E-sail) is a proposed form of spacecraft propulsion using the dynamic pressure of the solar wind...

materials for optimizing a solar sail, for instance. Momentary or hours long solar pressures can indeed escalate due to release of solar flares and coronal mass...

radiation pressure, which aids in the calculation of a force on a solar sail. Solar irradiance is measured by satellites above Earth's atmosphere, and...

The fission sail is a type of spacecraft propulsion proposed by Robert Forward that uses fission fragments to propel a large solar sail-like craft. It...

allocated funding. A preliminary mission outline suggests the use of solar sails propelled by high energy lasers to increase propulsion. The proposed...

employs a solar sail to continuously modify its orbit in ways that gravity alone would not allow. Typically, a statite would use the solar sail to "hover"...

between solar sail spacecraft. John Merton, a spaceship designer, develops and promotes a lightweight spacecraft with a large area of solar sail, to be...
