Solar sails were first developed at NASA's Jet Propulsion Laboratory in the 1960s and were demonstrated by Pioneer 10 in 1973. The graph below clearly shows that the efficiency of a solar sail ...

“Solar sail propulsion has the potential for rapid delivery of small payloads (sub-kilogram) throughout the solar system,” René Heller, ...

Solar sails, ultra-thin polymer “sails” that leverage the Sun’s photons as a means of propulsion, have been sent into orbit for more than a decade, but now NASA is prepping it’s own version.

NASA's Advanced Composite Solar Sail System (ACS3) ... Solar sails can theoretically also reach high speeds, as it is believed their unique method of propulsion can grant them infinite acceleration.

NASA's Advanced Composite Solar Sail System (ACS3) can be seen with the naked eye as it orbits Earth, and can be tracked with a helpful app.
