IKAROS (Interplanetary Kite-craft Accelerated by Radiation Of
the Sun) is a solar sail which gathers sunlight as propulsion by
means of a large sail. This solar powered sail craft will employ
both photon propulsion and thin film solar power generation
during its interplanetary cruise. The Planetary Society invited
the world to place messages into the Solar Sail. CHALK4PEACE
is sending this message into space:
"We ask others in the universe to join the planet Earth in
expressing their vision for intergalactic peace amongst peoples
and planets through CHALK4PEACE, which is a worldwide
sidewalk chalk painting project about peace. This event became
a global expression in 2006 AD. Its purpose is to draw the world
closer to peace because we have a lot to chalk about.
Simultaneous expression. Imagine Peace. chalk4peace.blogspot.com"
