subject: movie of Nanosail tumbling in space Movie of Nanosail made using frames taken 9 seconds apart. Only the very sharpest frames are used, less is more. The result looks remarkable ; this must be the first movie showing the Sail actually tumbling in space. Note that one rotation visible in the movie might actually be a compression of several rotations which could not be individually recorded due to lost frames, inevitable connected to the manually tracking method used with the very high imaging scale. http://freeimagehosting.nl/pics/7a80e9eb09b62849cad939b33884ffa2.gif Note the irregularity of illumination of certain parts of the Sail which could cause the sub-flashes observed by visual observers. To demonstrate how the part of the pass, presented in the movie would look like for the naked-eye, I have artificially lowered the resolution to spot-size, comparable with naked-eye view in the second smaller animation, containing the same frames; we see indeed flashing. http://freeimagehosting.nl/pics/9cb8a10740c73fc0ad3d17b1e9e2e042.gif Best regards, Ralf Vandebergh http://ralfvandebergh.startje.be/vieuw.php?qid=328303 -------------- next part -------------- An HTML attachment was scrubbed...
