Japan's OPENS Program Aims to Explore the Outer Solar System with Solar Sails

The OPENS program, initiated by Japan's space agency JAXA, is an ambitious project to explore the outer solar system using small solar sails. The project follows in the footsteps of the IKAROS mission, which in 2010 became the first to successfully deploy an interplanetary solar sail. OPENS will beg... [More info]

"Konstantin Tsiolkovsky may have begun to ponder the physics of rocket-propelled spaceflight as early as the 1870s ... [and was also] one of the first to propose solar sailing as a non-rocket form of space travel."
