It also does not include any future human missions to the planet.<\/p>\n<p>What the document does offer is a strategy of future robotic missions that can tackle key science questions about Mars, including any evidence of past or present life, while also laying the scientific groundwork for future crewed missions.<\/p>\n<p>The strategy has three \u201cco-equal\u201d science themes, said Becky McCauley Rench, program scientist in NASA\u2019s planetary science division and co-lead of the study. One, called \u201cexploring the potential for Martian life,\u201d is focused on looking for any evidence of life on Mars. \u201cDid life ever arise on Mars, and if so, does it exist today?\u201d she said. \u201cIf life never developed, why not?\u201d<\/p>\n<p>A second theme, \u201csupporting the human exploration of Mars,\u201d is looking at the \u201csynergistic observations\u201d that could be made with robotic missions ahead of the first crewed missions, including key knowledge gaps to fill. \u201cHow can we prepare to maximize that precious human time on the surface and the resources in connection with the export community here on Earth?\u201d she said.<\/p>\n<p>The third theme, called \u201crevealing Mars as a dynamic planetary system,\u201d includes other science topics, with an emphasis on comparative planetology. \u201cWe want to learn as much about Mars as we know about Earth,\u201d she said.<\/p>\n<p>To perform the science in those three themes, the plan advocates a regular series of mission, focusing on smaller spacecraft. \u201cThis program is looking at changing the paradigm of how we think about Mars missions,\u201d Ianson said. \u201cEvery opportunity there is when a launch window opens up, can we send something up?\u201d<\/p>\n<p>\u201cWe want to do that with lower-cost missions that are science driven and has the capability of providing flexible, rapid response to discoveries,\u201d said McCauley Rench, \u201cnot necessarily taking 10 years between thinking about a mission and actually seeing it launch.\u201d<\/p>\n<p>Those smaller missions, with projected costs of $100 million to $300 million each, would focus on specific scientific questions with a single instrument or small suite of instruments. NASA proposes to augment them with less frequent but larger missions with more complex instruments. An example would by the Mars Life Explorer lander concept included in the planetary science decadal survey.<\/p>\n<p>The plan also includes flying payloads as \u201cmissions of opportunity\u201d on missions by other space agencies or even commercial missions. Also included is revitalizing what Ianson called \u201ccritical and aging infrastructure\u201d at Mars such as communications relays and the high-resolution imagery currently provided by the nearly 20-year-old Mars Reconnaissance Orbiter.<\/p>\n<p>Infrastructure is one area where commercial partnerships may contribute to the plan. <a href=\"https:\/\/spacenews.com\/nasa-awards-studies-for-commercial-mars-missions\/\">NASA awarded studies in May to nine companies<\/a> to examine the feasibility of commercial systems to deliver payloads to Mars and to provide communications and imagery services.<\/p>\n<p>Ianson said the studies were promising. \u201cThere really is some merit here and we think there is something that merited further studies and further work,\u201d he said, such as how to structure any public-private partnerships to carry out such missions.<\/p>\n<p>One issue with commercial Mars missions, he said, will be the business case for companies performing such missions. A simple fee-for-service model, where NASA pays only for the services once provided, \u201cis probably not a totally workable solution,\u201d he said, based on the outcomes of the studies. \u201cThere probably needs to be some level of investment through a public-private partnership on the NASA side up front.\u201d<\/p>\n<p>The agency is taking initial steps to implement the strategy. NASA\u2019s 2025 budget proposal included $40 million to invest in Mars robotic exploration technologies. NASA is allocating $30 million of that to internal efforts, picking 25 projects out of 90 proposals received from agency centers. The remaining $10 million may be offered to industry and academia for \u201cinnovative robotic mobility technologies,\u201d Ianson said.<\/p>\n<p>The plan itself does not include any specific mission plans or budget requirements, and Ianson emphasized its flexibility. \u201cObviously, we would love to do everything in the plan. However, that\u2019s not realistic under challenging budget circumstances and competing priorities,\u201d he said. \u201cI look at this plan less as a roadmap but more as a menu of options to choose from, based on the availability of budget and the most pressing needs to support Mars science.\u201d<\/p>\n<p><h3 class=\"jp-relatedposts-headline\"><em>Related<\/em><\/h3>\n<\/p><\/div>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-3711241968723425\"\r\n     crossorigin=\"anonymous\"><\/script>\r\n<ins class=\"adsbygoogle\"\r\n     style=\"display:block\"\r\n     data-ad-format=\"fluid\"\r\n     data-ad-layout-key=\"-fb+5w+4e-db+86\"\r\n     data-ad-client=\"ca-pub-3711241968723425\"\r\n     data-ad-slot=\"7910942971\"><\/ins>\r\n<script>\r\n     (adsbygoogle = window.adsbygoogle || []).push({});\r\n<\/script><br \/>\n<br \/><div data-type=\"_mgwidget\" data-widget-id=\"1660802\">\r\n<\/div>\r\n<script>(function(w,q){w[q]=w[q]||[];w[q].push([\"_mgc.load\"])})(window,\"_mgq\");\r\n<\/script>\r\n<br \/>\n<br \/><a href=\"https:\/\/spacenews.com\/nasa-releases-long-term-strategy-for-robotic-mars-exploration\/\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>WASHINGTON \u2014 NASA has refined its strategy for future robotic exploration of Mars, advocating for a regular cadence of smaller missions to answer key questions in advance of human missions. &hellip; <a href=\"https:\/\/hotvideos24.online\/?p=138003\" class=\"more-link\">Read More<\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[8628],"tags":[],"class_list":["post-138003","post","type-post","status-publish","format-standard","hentry","category-science","entry"],"_links":{"self":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/posts\/138003","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=138003"}],"version-history":[{"count":0,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=\/wp\/v2\/posts\/138003\/revisions"}],"wp:attachment":[{"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=138003"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=138003"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/hotvideos24.online\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=138003"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
