In ecology, there used to be a concept \u2014 now largely unfashionable \u2014 that species could be described as r- or K-selected, depending on how they treat their offspring. An elephant that has one calf every few years and devotes immense resources to them is adopting a K-selection strategy \u2014 much as NASA traditionally has to its flagship probes, like Cassini. A sea turtle who leaves hundreds of eggs in a clutch on the beach and leaves without saying \u201cgood luck\u201d, content in the knowledge that one of them will probably make it to adulthood is engaging in an r-selected strategy, and it\u2019s this strategy that [Dr. Michael Rubenstein] is proposing for a next-generation mission to Saturn as part of NASA\u2019s Innovative Advanced Concepts Program for 2026. Entitled \u201cActively Steerable Femtosat Constellations for In-situ Exploration of Saturn\u2019s Rings, Atmosphere, and Magnetosphere<\/a>\u201d \"\"<\/a><\/p>\n

The concept is pretty simple: the rings are a horrifying mess of dust, debris, and ice bits of all sizes that represent almost certain death for a spacecraft. By launching 10,000 femtosatellites, those odds of almost certain death become an almost certainty that one or more will make it through with precious data. In the immortal words of Lord Farquhar, \u201cSome of you may die, but that is a sacrifice I am willing to make.\u201d With Cassini, NASA would never consider such a sacrifice. With itty-bity femtosatellites, it starts to make sense. We\u2019ve been saying for years that the future of space is tiny<\/a>, but these sacrificial probes would make even modern cubesats and picosatellites<\/a> look big.<\/p>\n

Thanks to [Richard HT] for the tip! His tip was to a podcast featuring [Dr. Rubenstein] with [Fraser Cain], which we\u2019ve embedded below. It has a lot more details than NASA\u2019s official blurb page.<\/p>\n","protected":false},"excerpt":{"rendered":"In ecology, there used to be a concept \u2014 now largely unfashionable \u2014 that species could be described…\n","protected":false},"author":2,"featured_media":595327,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[61,60,82,247],"class_list":["post-595326","post","type-post","status-publish","format-standard","has-post-thumbnail","category-space","tag-ie","tag-ireland","tag-science","tag-space"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/595326","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=595326"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/595326\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/595327"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=595326"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=595326"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=595326"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
