The video leaves me wanting to be able to go in and examine the changes more closely. Is there a compelling reason to feature this as opposed to the original NASA images as a set? 24.222.214.125 (talk) 02:41, 27 January 2015 (UTC)[reply]
Resolution, one would think (the 1980s image is far below the minimum) and the fact that the originals are all oriented differently. (The file description page links to the originals on Commons). — Crisco 1492 (talk) 02:59, 27 January 2015 (UTC)[reply]
