Hayne et al, Keck Institute for Space Studies (KISS) &#8211; April.2014 (pdf)<\/a><\/li>\n<\/ul>\n<p>From the report:<\/p>\n<p style=\"padding-left: 30px;\"><em>The first major goal of this study was to identify the outstanding questions about lunar volatiles that could be addressed by new observations. In order to define the key measurements, we identified two fundamental questions driving the science and exploration of lunar volatiles: <\/em><\/p>\n<p style=\"padding-left: 30px;\"><em>1. What are the origins and evolution of water in the inner Solar System? <\/em><br \/>\n<em>2. Where are the operationally useful deposits of water on the Moon? <\/em><\/p>\n<p><em>Existing data have only scratched the surface with regard to the abundance and distribution of water on the Moon, let alone its origins.<\/em><\/p>\n<p style=\"padding-left: 30px;\">[&#8230;]<\/p>\n<p style=\"padding-left: 30px;\"><em>The second major goal for this study was to seek ways to harness emerging small spacecraft technologies for low#cost lunar missions. Since their advent in the 1990\u2019s, nanosatellites (and the CubeSat form factor in particular) have rapidly evolved and are now routinely built (primarily by university students) and launched to low# Earth orbit (LEO) for science, technology, and education applications. With their rapid development times and extremely low cost compared to traditional spacecraft, nanosatellites and other small satellites present an exciting new paradigm to planetary science, if their capabilities can be proven beyond low Earth orbit. The Moon is ideally situated for the first of these missions. We therefore assessed whether or not one or more small satellite missions could accomplish the desired lunar ice detection measurements. <\/em><\/p>\n<p><em>In this report, we propose a new program of lunar science and exploration by small, low-cost spacecraft. Initially, this program will be guided by the above measurement goals relevant to detection and mapping of lunar volatiles, but could later be\u00a0expanded \u00a0to \u00a0other \u00a0investigations \u00a0of \u00a0the \u00a0Moon \u00a0and \u00a0beyond. \u00a0As \u00a0a \u00a0first \u00a0step, \u00a0we advocate \u00a0sending \u00a0a \u00a0\u201ctrailblazer\u201d \u00a0nanosatellite \u00a0to \u00a0a \u00a0polar \u00a0lunar \u00a0orbit, which would \u00a0carry a limited yet useful payload (see Section 5). The goal of this mission would be \u00a0to prove that scientifically valuable data on lunar volatiles could be acquired using a \u00a0nanosatellite \u00a0at \u00a0a \u00a0total \u00a0cost \u00a0of \u00a0&lt;$10M. \u00a0Some \u00a0of \u00a0the \u00a0key \u00a0technologies \u00a0needing \u00a0development are identified in this report. Following the pathfinder mission, one or \u00a0more \u00a0additional \u00a0small \u00a0satellites would \u00a0carry \u00a0instrumentation \u00a0specifically designed \u00a0for \u00a0the \u00a0measurements \u00a0outlined \u00a0above. \u00a0Ultimately, \u00a0we \u00a0envision \u00a0a \u00a0fleet \u00a0of \u00a0tiny \u00a0spacecraft, \u00a0each \u00a0with \u00a0its \u00a0own \u00a0specialized \u00a0yet \u00a0synergistic \u00a0payload \u00a0for \u00a0detecting, \u00a0mapping, and characterizing lunar ice deposits. If successful, such a program has the \u00a0potential to accomplish as much as a traditional spacecraft mission, at a fraction of \u00a0the \u00a0cost. \u00a0Finally, \u00a0this \u00a0program \u00a0could \u00a0pave \u00a0the way \u00a0for more \u00a0ambitious \u00a0spacecraft \u00a0missions \u00a0beyond \u00a0the \u00a0Moon, \u00a0thereby \u00a0opening \u00a0up \u00a0a \u00a0new \u00a0paradigm \u00a0in \u00a0planetary \u00a0exploration.<\/em><\/p>\n<p style=\"text-align: center;\">==============<\/p>\n<p>I&#8217;m managing editor at <a href=\"http:\/\/www,newspacewatch.com\" target=\"_blank\">NewSpace Watch<\/a>, which is part \u00a0of \u00a0<a href=\"https:\/\/www.newspaceglobal.com\/smallsatreport\" target=\"_d\">NewSpace Global<\/a>.
