Executive Summary Solar system exploration is ~~ grad humm endeavor which reaches out through in~rplmetary space to discover Me nature md origins of We system of planets in which we live md to learn whether life exists beyond Earth. It is ~ international enterprise invoking scientist, engineers' managers' politicians, md others' sometimes working together md sometimes in competition, to open new frontiers of knowledge. It has ~ proud past' productive present' md ~ auspicious future. Solar system exploration is ~ compelling activity. It places within our grasp answers to basic questions of profound humm interest: Are we alone: Where did we come from: What is our destiny: Furlers it leads to the erection of knowledge that will improve We humm condition. hIars md icy satellite explorations may soon provide ~ answer to the first of these questions. Exploration of comets, primitive asteroids, md Kuiper Belt objects may have much to say Rout the second. Surveys of near-Earth objects md further exploration of plme~ry atmospheres will show something about the third. Finally, explorations of all plenary environments will result in ~ much improved understanding of the natural processes that shape He world in which we live. This survey was requested by the Nations Aeronautics md Space Administration (NASA) to determine the contemporary nature of solar system exploration md why it remains ~ compelling aetivi~ today. A broad survey of the same of knowledge was requested. In Editions NASA asked for identification of the top-level seientif~e questions to guide its ongoing program md ~ prioritized list of the mod promising avenues for flight investigations md supporting ground-based activities. To accomplish this task, the Solar System Exploration Surveys (~SE Surveys) Leering Group md panels have worked with scientist, professional societies' NASA md Nations Science Foundation (NSF) officials' people ~ government md private laboratories' md members of He interested public. The remarkable breads md diversity in the subject are evident in the panel reports th~eonstitute Part Cole of this survey. Together Hey strongly reinforce He idea that ~ high-level inversion of He goals' ideas' md requirement that exist in the community is essential if ~ practical exploration spongy for the next decade is to emerge. Such ~ integrated stringy is Be objective of Part Two. CROSSCUTTING THEMES ANN KEY QIJESiTIONS Based on the material presented in Part One of this report He SSE Survey identified He following four erosmu~ing themes that form ~ appropriate basis for ~ indurated strategy that em be realized by ~ series of missions to be flown over the next decade:
HEW FR0~ IN =E 50~R HIM I. 1~ Fort Echo Years of So~r System History. This first Demo covers the formative period thy features the initial accretion md development of Earn arid its sibling plar~ts, including the emergence of life on our globe. This pivotal epoch in ~e solar systems history is only dimly glimpsed ~ premnt. 2. Vo~s ~d Of: ~ StuffafL~fe. The second theme addresses the reality thy life requires orgasm materials arid volatiles, notably, liquid wear. These marries originally condensed in the outer reaches of ~e solar nebula arid were Lear delivered to the ply aboard orgar~ic-rich comets md asteroids. 3. 1~ Orgy ~d Photo of H~ Worm. The Bird theme recognizes thy our concept of the ``habi~ble zone', he men overtumed' arid grayly broadened, by recent findings on Earth arid elsewhere through- out our galaxy. Taking inventory of our perry neighborhood will help to ~~e ~e evolutionary pays of ~e other plums arid the eventual fad of our own. 4. Process es: How Cry Yost Work. The fours Demo seeks deeper understanding of the fundamen- ta1 mechar~isms operating in the solar system today. Comprehending such processes arid how Hey apply to perry bodie~is the keystone of perry science. It will provide deep insight into the evolution of ~1 ~e worlds within the solar system arid of the multitude of pits being discovered around other stars. . . Devolving fromthesefour crosscutting themes are 12key scientific questions. Them are shown inTable ES.~' together win the names of the facilities arid missions recommended as the most appropriate activities to address these questions. The priority arid measurement objectives of these various projects are summarized in He next section. PllIOllITIES FOR FLIGHT MISSIONS AND ADVANCED TECHNOLOGY Progress on the tabulated scientific themes md key questions will require ~ series of spacefligh~ md support- ing Earth-based activities. It is cruet to maintain ~ mix of mission sins md complexities in order to balance available resources against po~ntia1 schemes for implementation. For example' certain aspects of the key science questions em be met Trough focused md eost-effeetive Discovery missions (c$325 million), while other high- priorily science issues will require larger' more capable projects, to be called New Frontiers. About once per decade' Flagship missions (:~$650 million) will be neeess~ for sample return or comprehensive investigations of particularly worthy Greets. Some future endeavors are so vast in scope or so difficult (e.g.' sample return from Mars) that no single nation Sting alone may be willing to Slovak all of He resources necessary to accomplish them, md the SiSE Survey recommend that NASA encourage and continue to pursue cooperative program with other nations. Not only is the investigation of our celestial neighborhood inherently ~ intern~iona1 venture' but He U.S. Solar System Exploration program will also benefit programmatieally md scientifically from such joint ventures. Discovery missions are reserved for ir~E~ovative mdeompetitively procured projects responsive to new findings beyond He nations long-term strategy. Such missions em satisfy mmy of the objectives identified in Part One by the individual pmels. Given Discovery's highly su~sful Carts the SSE Survey encore the continuation of this program' which relies on principal-investigator leadership and competition to obtain the greatest science return within ~ cost ~p. A night rate of no less than one launch every 18 months is Deck Particularly critical in this stringy is the initiation of New Frontiers, ~ line of medium-class, prineipal- inve~igator-led missions ~ proposed in the Presidents fiscal year (FY) 2003 budget. The SSE Survey strongly endorses the New Frontiers initiative. These spacecraft should he competitively procured and should have flights every 2 or 3 yearly with the total cost Upped at approximately twice that of ~ Discovery mission Target deletion should he guided hy the list in this report' Experience has shown that large missions' which enable detailed' extended' md seientif~eally multifaceted observations' are ~ essential element of the mission mix. They allow the comprehensive exploration of science targets of extraordinarily high interest. Comparable pay missions have included Viking' Voyager, Galileo' md Cassini-Huygens. The SSE Survey recommends that Flagship (~$650 million) minions he developed and flown at ~ rate of Shout one per deader In addition, for large missions of such inclusive scientific breadth, ~ h road ~s Action of the community should he involved in the early planing stages.

The evolution of life arid ply - environments are intimately tied together. To understand ~e po~ntia1 habitability of Mars, whether it has or has not supported life' we mud understar~d ~tonic, magm~ic' arid hydrologic evolution as well as geochemica1 cycles of biological relevance. The return of materials from known locations on Mars is essential in order to address science goals' including those of astrobiology, arid to provide the opportunity for novel measure- men~' such as age-d~ing, md ultimate ground true. Mars Scim~ Laboratory The Mars Science Laboratory (MSL) mission will conduct in situ investigations of ~ w~r-modified sin thy has ~~n identified from orbit. It will provide ground true for orbital interpretations arid ~st hypotheses for ~e formation of geological features. The types of in situ measurements possible include atmospheric sampling' mineralogy arid chemical composition, arid Ash for ~e presence of orgar~ics. The mission should eider drill to get below the homily surface environment or have subs~tia1 rarefying capability.
