Here's a much better translation of that photo caption, provided by Lionel Ward:
QUOTE
These are photographs taken after yesterday's completion of primary deployment. Due to intense sunlight, in the photograph there is the appearance that the two tethers connecting the sails to the probe's body are piled on top of each other. However, since the side of the sail close to the probe's body is in shadow, and the incident light there is weaker, we can confirm that the tether and membrane harness are photographed.

IKAROS planned today and confirmed that the state of posture data, images etc. to get done. IKAROS state is found to be made good.
For more data, so once the report tomorrow, please wait a moment.

Success.

From the IKAROS blog.

Japan Aerospace Exploration Agency (JAXA) is May 21, 2010 (Japan Standard Time, as follows:
Like) was launched from Tanegashima in the application of the IKAROS, June 3
Began to hoist the sail, the distance from the Earth about 770 million on October 6 km at the Sail
Stretched, and was confirmed by photovoltaic power generation.
Continue to measure the status of PV power generation patents or photon acceleration using a pressure
We demonstrate Bisoreniyoru orbit control, navigation through the acquisition of solar sail technology


QUOTE
It ended with a final check image expansion operation yesterday, will announce the successful deployment of state to sail solar power. Also check the power of thin film solar cells on the surface of sail that followed, IKAROS minimum mission success achieved!
For images, etc. We will also open more channels of specialized pursuit.

While the sail doesn't really look deployed from this awkward angle, remember these cameras are near edge-on with the sail and there is a large gap between IKAROS and its sail.

Emily reports that the sail is fully deployed & IKAROS is power-positive; congratulations to the project and to JAXA!!! smile.gif

This is truly historic; a pioneering first by any standard. Can hardly wait to hear how he (is IKAROS a he?) performs during his shakedown cruise!

All that needs to be done now is for IKAROS to deploy those two free-floating cameras and photograph the sail in all its beauty smile.gif

Can't wait for the images from the free floating cameras.
Looking at that diagram above, it looks like the deployment-view cameras overlap, but it's a bit hard to find anything to match up in each image.
Rather than fudge it, here's a foreshortened polar view created from the four sail-deploy images with no overlap attempted.

I hope they deploy that free-floating camera soon. Totally looking forward to seeing IKAROS in all its kite-shaped beauty

Anyone notice the IKAROS twitter profile pic keeps getting sadder and sadder? It's practically crying a flood now. Hilarously cute.

Why would it be getting sadder? Is something not going well???

Maybe it's getting sadder 'cause it knows that brother Hayabusa most likely doesn't have any samples inside its capsule. I kid. biggrin.gif

Mmm...close! According to my wife, the latest tweets are an imaginary conversation between IKAROS & Hayabusa (messages of encouragement for the latter.) Guess the tears are for Hayabusa-san's impending EOM.

IKAROS has stopped crying...while Akatsuki has been smiling the whole time. Must have had a beef with his older brother. smile.gif

Looks like the first of two free-floating cameras (DCAM 2) will be deployed from IKAROS today

And the IKAROS Twitter avatar is happy again. smile.gif

Seems free-floating DCAM2 has been released and the camera twitters here: http://twitter.com/DCAM2


Heh, Ikaros and DCAM2 are twittering about imaging.
