Until very recently only half of the planet\u2019s surface had been imaged, making it the least well explored planet in the inner Solar System.\u00a0 Jack\u2019s geological map covers an area of about five million square kilometres, or half the area of the USA, on the side of the planet imaged for the first time by NASA\u2019s MESSENGER satellite.<\/p>\n<p><span style=\"line-height: 1.5;\">Edmond Halley made the voyage to the southern hemisphere in order to map the stars to aid navigation at sea. Whilst on St Helena he observed a transit of Mercury, which passed in front of the Sun as seen from Earth.\u00a0 Mercury will transit the Sun again on 9 May this year, giving everyone in the UK a chance to see it.\u00a0 The Open University has released a new video about safe viewing <\/span><a style=\"line-height: 1.5;\" href=\"http:\/\/www.open.edu\/openlearn\/science-maths-technology\/science\/physics-and-astronomy\/astronomy\/discover-mercury-safety-advice-the-transit-mercury\">here<\/a><span style=\"line-height: 1.5;\">.<\/span><\/p>\n<p>&nbsp;<\/p>\n<div id=\"attachment_2231\" style=\"width: 328px\" class=\"wp-caption alignright\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-2231\" class=\" wp-image-2231\" src=\"https:\/\/www.open.ac.uk\/blogs\/news\/wp-content\/uploads\/2016\/02\/Block_diagram-300x163.png\" alt=\"Lobate scarp diagram\" width=\"318\" height=\"173\" srcset=\"https:\/\/www.open.ac.uk\/blogs\/news\/wp-content\/uploads\/2016\/02\/Block_diagram-300x163.png 300w, https:\/\/www.open.ac.uk\/blogs\/news\/wp-content\/uploads\/2016\/02\/Block_diagram-768x418.png 768w, https:\/\/www.open.ac.uk\/blogs\/news\/wp-content\/uploads\/2016\/02\/Block_diagram.png 1016w\" sizes=\"auto, (max-width: 318px) 100vw, 318px\" \/><p id=\"caption-attachment-2231\" class=\"wp-caption-text\"><em>Diagram of a lobate scarp<\/em>The large ridge \u2013 or \u2018lobate scarp\u2019 \u2013 that Jack identified is 350 km long and 1.5 km high. Jack commented:\u00a0\u201cI see Mercury as the \u2018problem child of the Solar System\u2019 since so much about the planet defies our expectations and our attempts to study it.\u00a0 I feel privileged to be studying this complex and fascinating planet and delighted that my suggestion for naming this feature has been accepted. My next task is to examine the scarp in further detail to find out more about the history of this part of Mercury\u2019s surface.\u201d<\/p><\/div>\n<p>David Rothery, Professor of Planetary Geosciences, who is leading the Open University\u2019s study of Mercury and has previously had <a href=\"http:\/\/www.bbc.co.uk\/news\/uk-wales-28010435\">various name suggestions of his own approved <\/a>\u00a0said: \u201cI suggested to Jack that we needed a name for this feature, which is so much more convenient than having to refer to it as \u2018the long scarp near the southeast corner of our map\u2019. The convention is that scarps on Mercury are named after ships used on \u2018voyages of discovery\u2019, and when Jack dug out the name of the ship that took Halley to St Helena it seemed perfect.\u201d<\/p>\n<p>If you&#8217;re interested in learning more about Mercury, watch our <a href=\"http:\/\/www.open.edu\/openlearn\/discovermercury?in_menu=334025\">series of videos<\/a> on OpenLearn.<\/p>\n<p>The Open University&#8217;s research in Mercury is funded by the Science and Technologies Facilities Council (STFC) and the UK Space Agency.
