NASA's Advanced Composite Solar Sail System (ACS3), a dazzling spacecraft designed to make use of the tiny amounts of radiation pressure exerted by sunlight for propulsion, is still spinning ...

Somewhat mirroring the Renovare Fuel model ... efficiency issues around a solar panel’s ability to collect maximum levels of sunlight. For Nectar Design these inefficiencies could provide a ...

NASA has released the first look at its Advanced Composite Solar Sail ... even spot the sail above them. The ACS3 launched back in April, and has since spent its time spinning through its sun ...

A solar sail is designed to capture the tiny amounts of radiation pressure exerted by sunlight to propel a spacecraft to incredible speeds. The advantages are numerous: by acting like a sailing ...

Mission controllers have to account for the solar sail's spin rate, distance to the sun and the sun angle to plot the spacecraft's course. An almost day-long test of the steering took place ...
