IKAROS sounds really cool, is there any website to find more info on it?

Hello, I once found one abstract on the project page telling that it is indeed possible to change the rotation rate via the solar pressure on areas of the sail, or better that it will be part of the experiment to verify this technique. The idea behind that it not "simply" brightening and darkening of areas, but to switch between diffuse and specular reflection. I also have one question (because the google translation of Japanese leaves me quite clueless): Is there a difference between the 2 DCAMs (something about 'separate antennas' and 'only one has a receiver' comes out of google's translation attempts)? Has only one been deployed so far? source: http://www.jspec.jaxa.jp/ikaros_channel/bn006.html -------------------- We know there are plants on Mars, but NASA screwed that up and landed their landers only in the deserts.

I think I understand that only DCAM1 has a receiving antenna on its housing on IKARUS, and DCAM2 uses that of DCAM1 |
