<i>> Bush does not make a convincing case for the VSE. </i><br /><br />Two points to consider on other's making of 'the case for space' in the recent past. During the 2004 campaign the only time I recall a politician mentioning space was Teresa Heinz Kerry calling for full cancellation of VSE and continued use of robotic probes only. In the 90s, NASA's policy was "Shuttle-station forever" - they were planning on flying STS through the 2020s and do nothing more than LEO missions with the occasional probe. Which is more exciting? A multi-planet, human strategy conveyed in halting words or more of the same LEO circles spoken of eloquently?<br /><br /><i>> He does not provide any rationale for terminating the shuttle and station after so many years of effort to perfect them. </i><br /><br />Shuttle is only flying to complete the station. There is no "perfection" involved, it is a fairly old, experimental spacecraft that never lived up to it's potential, despite the amazing things that have happened with it. Station has changed so many that they just want to get what they have finished. ISS is not going to be terminated, it is being brought to a state of usability so that NASA isn't the only US group supporting it. Congress recently voted to make it into a National Lab and encourage other uses. <br /><br /><i>>He gives no explanation of why going to Mars is more "relevant" than aeronautics or environmental science, and shows no understanding of how the Mars mission can actually be accomplished or what it will cost. </i><br /><br />The president's science adviser, Dr. Marburger, has spelled this out in more detail. The goal isn't Mars, it's to bring the Inner Solar System into the human economic sphere. That is something far larger than NASA or the whole Federal government, is capable of. Opening space up will take a level playing field among corporate, public and academic interests, luck and determination from all involved. Mars is a good mid-term goal (Moon, then Mars, <div class="Discussion_UserSignature"> <div align="center"><em>We need a first generation of pioneers.</em><br /></div> </div>
