Media are invited to learn about NASA’s next-generation solar sail technology – known as the Advanced Composite Solar Sail System – that could enable ambitious lower-cost missions to expand our understanding of the Sun and solar system. 

The event will occur from 10-11 a.m. on Tuesday, April 16, at NASA’s Langley Research Center in Hampton, Virginia. Project researchers will be available to discuss the solar sail technology, which uses the pressure of sunlight to travel through space much like a sailboat uses wind to traverse the ocean. A full-scale engineering design unit of the polymer sail and its novel lightweight composite booms will also be on display at the event. 

The Advanced Composite Solar Sail System is scheduled to launch during a 30-day window that opens no earlier than Wednesday, April 24 aboard a Rocket Lab Electron launch vehicle from the company’s Launch Complex 1 in New Zealand. The system is a part of a “12U” sized CubeSat and will deploy after on-orbit systems checks, which are expected to take approximately two months.    

Media interested in attending must contact Joe Atkinson at joseph.s.atkinson@nasa.gov no later than noon, Monday, April 15.
