More than four months after launching to space, NASA's Advanced Composite Solar Sail System (ACS3) has successfully deployed its solar sail, marking a significant milestone in the development of solar ...

New study assesses where light-powered spacecraft propulsion technology currently stands.

NASA has launched the latest attempt to test solar sail propulsion technology. The ACS3’s solar sail is made of a reflective polymer and is held by a boom made of carbon fiber composite material.

We need to make bigger solar sails from materials that can take high temperatures. Taking high temperatures means the solar sails could fly closer to the sun. If we got four times closer to the sun ...

Solar sails are an exciting way to travel through the solar system because they get their propulsion from the sun. NASA has developed several solar sails, and their newest, the Advanced Composite ...

Solar sails represent one of the most elegant concepts in space exploration: using sunlight itself to propel spacecraft through the cosmos without any fuel. But these thin, light giants face a ...

A promising space technology remains largely unexploited: solar sails. These lightweight structures, propelled by the pressure of solar radiation, have only been tested in a few missions. Yet their ...

For most spacecraft, traveling through the vacuum of space requires fuel. NASA's experimental Advanced Composite Solar Sail System (ACS3) is different, though. This vehicle could help NASA learn how ...
