Japan unfurls Ikaros solar sail in space
TOKYO. June 11. KAZINFORM Japanese scientists are celebrating the successful deployment of their solar sail, Ikaros; Kazinform refers to BBC News.
The 200-sq-m (2,100-sq-ft) membrane is attached to a small disc-shaped spacecraft that was put in orbit last month by an H-IIA rocket.
Ikaros will demonstrate the principle of using sunlight as a simple and efficient means of propulsion.
The technique has long been touted as a way of moving spacecraft around the Solar System using no chemical fuels.
The mission team will be watching to see if Ikaros produces a measurable acceleration, and how well its systems are able to steer the craft through space.
The Japan Aerospace Exploration Agency (Jaxa) said in a statement that its scientists and engineers had begun to deploy the solar sail on 3 June (JST).
On 10 June, Jaxa said, confirmation was received that the sail had expanded successfully and was generating power through the thin-film solar cells embedded in the membrane
The deployment occurred about seven million km from Earth.
