Two projects were conceived by NASA's Solar System Exploration Committee in 1983, the <a href="/wiki/Planetary_Observer_program" title="Planetary Observer program">Planetary Observer program</a>, and Mariner Mark II. </p><p>The Observer program, starting with the <a href="/wiki/Mars_Observer" title="Mars Observer">Mars Observer</a>, was envisioned as a series of low-cost missions to the <a href="/wiki/Inner_Solar_System" class="mw-redirect" title="Inner Solar System">inner Solar System</a>, based on commercial Earth satellites, while the Mariner Mark II was to be a series of large spacecraft for the exploration of the <a href="/wiki/Outer_Solar_System" class="mw-redirect" title="Outer Solar System">outer Solar System</a>. </p><p>Mariner Mark II spacecraft were to use common design, hardware and software solutions, much of it derived from previous missions such as <a href="/wiki/Voyager_program" title="Voyager program">Voyager</a> and <a href="/wiki/Galileo_(spacecraft)" title="Galileo (spacecraft)">Galileo</a> as well as select new technologies, such as advanced gyroscopes, all with the aim of cutting costs. It was hoped that this new approach would reduce the mission costs to about $400 million each, about half the price of Galileo. </p><p>The first two missions of the project were to be a mission to Saturn and its moon Titan, the <a href="/wiki/Saturn_Orbiter/Titan_Probe" class="mw-redirect" title="Saturn Orbiter/Titan Probe">Saturn Orbiter/Titan Probe</a>, or SOTP (later <i><a href="/wiki/Cassini%E2%80%93Huygens" title="Cassini–Huygens">Cassini</a></i>) and the <a href="/wiki/Comet_Rendezvous_Asteroid_Flyby" title="Comet Rendezvous Asteroid Flyby">Comet Rendezvous Asteroid Flyby</a> (CRAF), both of which were approved by Congress in 1990. </p><p>Other planned Mariner Mark II-based spacecraft were an <a href="/wiki/ESA" class="mw-redirect" title="ESA">ESA</a> led follow-on to CRAF, the <a href="/wiki/Comet_Nucleus_Sample_Return" class="mw-redirect" title="Comet Nucleus Sample Return">Comet Nucleus Sample Return</a> or CNSR (later <i><a href="/wiki/Rosetta_space_probe" class="mw-redirect" title="Rosetta space probe">Rosetta</a></i>, without the sample return); <i><a href="/wiki/Pluto_Fast_Flyby" class="mw-redirect" title="Pluto Fast Flyby">Pluto Fast Flyby</a></i>, a flyby of Pluto (later <i><a href="/wiki/Pluto_Kuiper_Express" title="Pluto Kuiper Express">Pluto Kuiper Express</a></i>, eventually realized as <i><a href="/wiki/New_Horizons" title="New Horizons">New Horizons</a></i>); and a <i><a href="/wiki/Neptune_Orbiter" class="mw-redirect" title="Neptune Orbiter">Neptune Orbiter</a></i> with an atmospheric probe. </p><p>However, congressionally imposed reductions to FY 1992–93 funding requirements forced NASA to terminate the CRAF mission and to delay the <i>Cassini</i> launch from April 1996 to October 1997. In order to save it, NASA was forced to significantly redesign <i>Cassini</i> to reduce the total program cost, mass and power requirements. </p><p>NASA has had to replace the <i>Mariner Mark II</i> program with the lower-cost <a href="/wiki/Discovery_Program" title="Discovery Program">Discovery Program</a>. </p> <div class="mw-heading mw-heading2"><h2 id="See_also">See also</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Mariner_Mark_II&action=edit&section=2" title="Edit section: See also"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a href="/wiki/Mariner_program" title="Mariner program">Mariner program</a></li> <li><a href="/wiki/Voyager_program" title="Voyager program">Voyager program</a></li> <li><a href="/wiki/Pioneer_program" title="Pioneer program">Pioneer program</a></li></ul> <div class="mw-heading mw-heading2"><h2 id="External_links">External links</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Mariner_Mark_II&action=edit&section=3" title="Edit section: External links"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <ul><li><a rel="nofollow" class="external text" href="http://www7.nationalacademies.org/ssb/crafcassini88.html">"Assessment of CRAF and Cassini missions"</a> <a rel="nofollow" class="external text" href="https://web.archive.org/web/20090318062429/http://www7.nationalacademies.org/ssb/crafcassini88.html">Archived</a> 2009-03-18 at the <a href="/wiki/Wayback_Machine" title="Wayback Machine">Wayback Machine</a> by Dr. Robert O.
