Solar Sail 0

From the BBC:

Japanese scientists are celebrating the successful deployment of their solar sail, Ikaros.

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.

Some sites that I link to may try to track you, but that's between you and them, not you and me.

I do collect statistics, but I use a simple stand-alone Wordpress plugin, not third-party services such as Google Analitics over which I have no control.

Finally, this is website is a hobby. It's a hobby in which I am deeply invested, about which I care deeply, and which has enabled me to learn a lot about computers and computing, but it is still ultimately an avocation, not a vocation; it is certainly not a money-making enterprise (unless you click the "Donate" button--go ahead, you can be the first!).

I appreciate your visiting this site, and I desire not to violate your trust.
