Mission controllers expect images from the encounter to arrive on Earth within 24 to 48 hours.<\/em><\/p>\n<p style=\"padding-left: 30px;\"><em>Mission scientists have hopes of seeing different terrain on Hyperion than the mission has previously explored in detail during the encounter, but this is not guaranteed. Hyperion (168 miles, 270 kilometers across) rotates chaotically, essentially tumbling unpredictably through space as it orbits Saturn. Because of this, it\u2019s challenging to target a specific region of the moon&#8217;s surface, and most of Cassini&#8217;s previous close approaches have encountered more or less the same familiar side of the craggy moon.<\/em><\/p>\n<p style=\"padding-left: 30px;\"><em>Cassini scientists attribute Hyperion&#8217;s unusual, sponge-like appearance to the fact that it has an unusually low density for such a large object &#8212; about half that of water. Its low density makes Hyperion quite porous, with weak surface gravity. These characteristics mean impactors tend to compress the surface, rather than excavating it, and most material that is blown off the surface never returns.<\/em><\/p>\n<p style=\"text-align: center;\"><a href=\"http:\/\/saturn.jpl.nasa.gov\/photos\/imagedetails\/index.cfm?imageId=1762\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"10671\" data-permalink=\"https:\/\/hobbyspace.com\/Blog\/?attachment_id=10671\" data-orig-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/05\/PIA07740-br5001.jpg\" data-orig-size=\"500,500\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;,&quot;orientation&quot;:&quot;0&quot;}\" data-image-title=\"PIA07740-br500[1]\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/05\/PIA07740-br5001.jpg\" class=\"aligncenter size-full wp-image-10671\" src=\"http:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/05\/PIA07740-br5001.jpg\" alt=\"PIA07740-br500[1]\" width=\"500\" height=\"500\" srcset=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/05\/PIA07740-br5001.jpg 500w, https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/05\/PIA07740-br5001-150x150.jpg 150w, https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2015\/05\/PIA07740-br5001-300x300.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><em>Here&#8217;s <a href=\"http:\/\/saturn.jpl.nasa.gov\/photos\/imagedetails\/index.cfm?imageId=1762\" target=\"_blank\">a view<\/a> of\u00a0Hyperion when Cassini made a\u00a0close pass in 2005.<\/em><\/p>\n<p>*\u00a0<a href=\"http:\/\/saturn.jpl.nasa.gov\/photos\/imagedetails\/index.cfm?imageId=5192\" target=\"_d\">Cassini Solstice Mission: Rhea&#8217;s Horizon<\/a><\/p>\n<p style=\"padding-left: 30px;\"><em>Gazing off toward the horizon is thought-provoking no matter what body&#8217;s horizon it is.
