Solar-Powered Spacecraft Speeding Through Space

ikaros-2
The IKAROS solar-powered spacecraft launched by the Japanese space agency JAXA is officially propelling through space using only solar energy.

After a successful launch on May 21, the craft's 3,000-square-foot sail unfurled without incident and online order prescription viagra today it was confirmed that IKAROS was harnessing the sun's rays and speeding through space.  The team of levitra overnite scientists back on the ground will control the vignovin.com craft's velocity by changing the angle of the sail, which will maximize or minimize the amount of radiation hitting the solar cells.

The team measured the thrust from the solar light pressure at 1.12 mili-Newton, which is what they expected.  You can check out JAXA's press release here for charts of the craft's acceleration and more details.

The IKAROS is the first fully solar-powered space craft to attempt to fda approves cialis reach deep space.

Solar "power", but not the levitra prescriptionsgeneric levitra sale way you think :)

to make it more clear: this project uses "solar sailing", capturing momentum from photons impacting on is viagra different from levitra the sail itself and in part from solar wind, the thin solar cells (small black rectangles) are for powering up the electronics, but the speed don't come from electricity!

...No it won't last but it will fade eventually due to distance traveling away from the sun. Their solution (from what i have learned - DISCOVERY CHANNEL) is that they will bombard this with laser that is generated from the spacecraft itself. Pardon me if my idea i got was wrong (just sharing though). Thanks...smilies/cool.gif

This is the first solar-sail powered spacecraft I've heard of. I wonder what the current velocity is. Your other post on this mentions "solar cells" in the sails. Are those PV, and hence generating electricity while also catching photons for actual forward drive?

Very, very cool. Sounds like a tiny sail and craft, but still really interesting stuff. I know they've also theorized about powering these from earth-based lasers, but I don't see any mention of that. Thanks or the only now generic viagra write up.

I just did a quick back of the envelope calculation assuming that the acceleration is constant and non-relativistic effects, and the solar sail will reach the speed of light in almost 10 years exactly. Of course this is wrong due to relativity and because the acceleration will decrease as it moves away from the sun. BUT in 10 days it will be traveling at 2 million mph, and I think my assumptions are okay here.
