In the dark before dawn, the rover\u2019s left navigation camera used its maximum long-exposure time of 3.28 seconds for each of 16 individual shots, all of which were combined onboard the camera into a single image that was later sent to Earth. In total, the image represents an exposure time of about 52 seconds.<\/p>\n<p>The low light and long exposures add digital noise, making the image hazy. Many of the white specks seen in the sky are likely noise; some may be cosmic rays. Two of the brighter white specks are Regulus and Algieba, stars that are part of the constellation Leo.<\/p>\n<p>Image credit: NASA\/JPL-Caltech<\/p>\n","protected":false},"excerpt":{"rendered":"NASA\u2019s Perseverance rover captured this view of Deimos, the smaller of Mars\u2019 two moons, shining in the sky&hellip;\n","protected":false},"author":2,"featured_media":104662,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3844],"tags":[790,48150,18863,70,413,16,15],"class_list":{"0":"post-104661","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-mars","9":"tag-mars-moons","10":"tag-perseverance-rover","11":"tag-science","12":"tag-space","13":"tag-uk","14":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/114514235472727774","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/104661","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=104661"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/104661\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/104662"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=104661"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=104661"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=104661"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
