Engineers saw this viewing opportunity and actually changed the orbit of Mars Express to be able to see it. Phobos passed a mere 11,400 km (6800 miles) away when these shots were taken, but Jupiter was 530 <em>million<\/em> km (320 million miles) in the background. That&rsquo;s why a moon only 27 km (16 miles) across can appear to dwarf a planet 140,000 km (86,000 miles) across! In the diagram here, the relative positions of all four players is shown; click to enbarsoomenate.<\/p><p>The animation consists of 104 frames taken over a period of just over one minute. It&rsquo;s useful, too. By knowing the position of the spacecraft and Jupiter, the orbit of Phobos itself can be better determined. Phobos is weird: it orbits so close to Mars ...<\/p><p><a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/feedads.g.doubleclick.net\/~a\/VU8L1niRHYFzeHAkCnuphmiTFfg\/0\/da\"><img decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/00a32_di\" border=\"0\" style=\"padding-left:10px; padding-right: 10px;\"><\/a><br><a rel=\"nofollow\" target=\"_blank\" href=\"http:\/\/feedads.g.doubleclick.net\/~a\/VU8L1niRHYFzeHAkCnuphmiTFfg\/1\/da\"><img decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/00a32_di\" border=\"0\" style=\"padding-left:10px; padding-right: 10px;\"><\/a><\/p><p><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/00a32_vJj_SWQHlZY\" height=\"1\" width=\"1\" style=\"padding-left:10px; padding-right: 10px;\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/euvolution.com\/futurist-transhuman-news-blog\/wp-content\/plugins\/wp-o-matic\/cache\/00a32_URWhbMj_f3M\" height=\"1\" width=\"1\" style=\"padding-left:10px; padding-right: 10px;\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Mars Express is a European Space Agency probe that&rsquo;s been orbiting the Red Planet since 2003, returning vast amount of data.
