Sora no Otoshimono is known for its unconventional ED animation, changing every time to go with the theme of the particular episode. And for the ED sequence of episode 6, IKAROS made an appearance!

No no no, not Ikaros the character, IKAROS (Interplanetary Kite-craft Accelerated by Radiation Of the Sun) the experimental spacecraft from JAXA! :D

I found it a really nice touch to have Ikaros trying to take a picture of the Earth from space, only to have IKAROS passing right in front when she snapped the photo. With the sunlight reflecting off the sails, the animated IKAROS looks more attractive than the official illustrations and 3D CG, too! XD
