The image was acquired by a tiny camera ejected from the central hub of Ikaros.
BBC: Mini-camera pictures Japan's Ikaros solar sail
Ikaros was launched as a piggy-back mission to Japan's Akatsuki Venus orbiter on 20 May (GMT).
They will also attempt to change the direction of Ikaros by altering the angle of the sail.
It is the picture that confirms Japan's Ikaros solar sail is fully extended and ready for the next part of its mission.
Ikaros will demonstrate the principle of solar sailing, which has long been touted as a means of moving spacecraft around the Solar System.
Ikaros on the other hand will push on past the planet.
We're also happy to see that several of our favorite solar houses from the show made it to the top ranks, including Germany's elegant IKAROS house, the ultra-efficient Armadillo Box, and Finland's beautiful wooden Luukku house.
