Diana-I Solar Sailer makes space travel comfortable, recreational

The Diana-I Solar Sailer, designed by John Lightbody, is a visionary spacecraft concept that prioritizes human comfort and well-being for long-duration space travel. Unlike conventional spacecraft that treat passengers as cargo, the Diana-I is designed as a livable space akin to a recreational vehicle, featuring amenities such as a kitchen, bed, shower, and dining area.

The adjustable sail offers pilots control similar to a boat’s rigging, making it a sustainable option for long-term exploration within the
