The results from that mission have substantially changed our perception of the asteroid belt, and in particular have confirmed the ubiquity of water ice in all parts of the solar system. Of course, it also raised a lot of questions, such as what was responsible for bright surface markings on Ceres, and how the dwarf planet could apparently have supported both ammonia deposits and a large ocean at various times in its history.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignright is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/cdn.mos.cms.futurecdn.net\/PpKzo7UMEqu8kgXjCehGJC-970-80.jpg\" alt=\"\" width=\"315\" height=\"300\"\/><figcaption>Pallas, as seen from the European Southern Observatory<\/figcaption><\/figure><\/div>\n\n\n\n<p>Anyway, I read this week that NASA is considering a smaller and cheaper mission to the third largest asteroid, Pallas. If approved &#8211; and the decision will be made later this month &#8211; this would launch in August 2022, which gives it a suitable orbit for a gravity assist from Mars. Unlike Dawn, the low price tag means that this is a flyby mission rather than one that aims to go into orbit, so it will be a case of capturing whatever data can be obtained in a relatively short span of time. Basically, it&#8217;s cheaper and easier to just race past somewhere, rather than carry the fuel to slow down and be captured gravitationally. Nevertheless, it should provide another batch of results to extend our knowledge of the diverse objects making up the asteroid belt. And in particular it will give some more solid information that &#8211; no doubt &#8211; wil one day find its way into my <em>Far from the Spaceports<\/em> series!<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignright is-resized\"><img loading=\"lazy\" decoding=\"async\" src=\"http:\/\/richardabbott.datascenesdev.com\/blog\/wp-content\/uploads\/2017\/03\/Kindle-Cover-768x1024.jpg\" alt=\"Kindle Cover - Half Sick of Shadows\" class=\"wp-image-1365\" width=\"222\" height=\"296\" srcset=\"http:\/\/richardabbott.datascenesdev.com\/blog\/wp-content\/uploads\/2017\/03\/Kindle-Cover-768x1024.jpg 768w, http:\/\/richardabbott.datascenesdev.com\/blog\/wp-content\/uploads\/2017\/03\/Kindle-Cover-225x300.jpg 225w, http:\/\/richardabbott.datascenesdev.com\/blog\/wp-content\/uploads\/2017\/03\/Kindle-Cover.jpg 1800w\" sizes=\"auto, (max-width: 222px) 100vw, 222px\" \/><figcaption>Kindle Cover &#8211; Half Sick of Shadows<\/figcaption><\/figure><\/div>\n\n\n\n<p>And in entirely unrelated news, last Friday I had the pleasure of participating in Helen Hollick&#8217;s blog series &#8220;Novel Conversations&#8221;, which focused on an interview with a character.
