Nasa has unfurled a solar sail in space for the first time, aiming to harness the propulsive power of sunlight for interstellar travel. The US space agency revealed that it had deployed the solar sail ...

Turns out, it's as tough to drop inward into the inner solar system, as it is to head outward. The problem stems from losing momentum from a launch starting point on Earth. It can take missions ...

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 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 ...

It’s not every day we hear of a new space propulsion method. Even rarer to hear of one that actually seems halfway practical. Yet that’s what we have in the case of TFINER, a proposal by [James A.

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.

Despite a failed first attempt, NASA deployed its pioneering solar sail system, which will harness energy from the Sun to propel itself forward through space. The Advanced Composite Solar Sail System ...

NASA is about to test its Advanced Composite Solar Sail System, which if is successful will unlock a new method of cheap space travel in the solar system and perhaps even beyond. On April 23 NASA ...
