I was a member of the original roadmap team, and we worked hard to craft a complementary set of missions that was both amibitious yet affordable; a lot of groups took one for the team, recognizing that their favorite proposals would weigh down the final document and make it look like a wish list rather than a realistic program.  Congress and OMB liked what we put together, and made it a part of NASA&#8217;s long-term budget.<\/p>\n<p>We highlighted five missions.  Two had well-defined mission concepts:  <a href=\"http:\/\/beyondeinstein.nasa.gov\/program\/lisa.html\">LISA<\/a> to search for gravitational waves and <a href=\"http:\/\/beyondeinstein.nasa.gov\/program\/constellation-x.html\">Constellation-X<\/a> to look at X-rays.  Three <a href=\"http:\/\/beyondeinstein.nasa.gov\/program\/probes.html\">probes<\/a> were in development and would be competed to choose a final version:  a dark-energy probe (which morphed into the joint NASA\/DOE dark energy mission), a black-hole finder to map the X-ray sky, and a search for polarization induced by gravitational waves in the CMB.  For future possibilities we highlighted two <a href=\"http:\/\/beyondeinstein.nasa.gov\/program\/vision.html#black%20hole%20imager\">vision missions<\/a>: a Big Bang Observer to directly detect the gravity-wave background from inflation, and a Black Hole Imager to resolve X-rays from right next to the event horizons of black holes.<\/p>\n<p><img class='center' width='498' src='http:\/\/blogs.discovermagazine.com\/cosmicvariance\/files\/uploads\/newflowchart.jpg' alt='Beyond Einstein' \/><\/p>\n<p>Subsequently, of course, NASA has decided that it has other priorities; primarily, visiting the <a href=\"http:\/\/blogs.discovermagazine.com\/cosmicvariance\/2006\/06\/29\/science-vs-mars\/\">Moon and Mars<\/a>.  That is too expensive to undertake while we&#8217;re squandering money on actual &#8220;science,&#8221; so some <a href=\"http:\/\/scienceandreason.blogspot.com\/2006\/11\/beyond-einstein.html\">tough choices<\/a> are going to be made.  The current plan is to pick one of the above five missions (not including the vision concepts), and give it a budget slice.  Maybe one of the others will get done, someday.<\/p>\n<p>So a <a href=\"http:\/\/www7.nationalacademies.org\/bpa\/Beyond_Einstein.html\">high-powered National Academy committee<\/a> is examining everything closely, deciding what to keep and what to kill.  I&#8217;m sure that&#8217;s not a fun job.  <a href=\"http:\/\/scienceblogs.com\/catdynamics\/2007\/04\/beyond_einstein_iv_showdown_in.php\">Steinn&#8217;s report<\/a> gives a nice informal review of what the committee is hearing, and to a lesser extent what they&#8217;re thinking.
