IKAROS

More IKAROS views
Some more pictures with and info about the cameras released to view the Japanese IKAROS solar sail from a distance:
/-- See the solar sail in space - Cosmic Log - June.17.10
/-- Small Solar Power Sail Demonstrator 'IKAROS' Successful Image Shooting by Separation Camera - JAXA - June.17.10

Haven't seen an estimate yet as to when they will be able to measure an acceleration with the sail. It's a fairly small sail so I suspect it could be quite awhile.

A nice sequence of pictures from the free floating cameras start at about 1 minute into this video
