Farewell Klipper.<blockquote><font class="small">In reply to:</font><hr /><p>Kliper Has Too Many Unknowns<br /><br />Excited scientists and members of the media gather round the Russian Kliper. <br />by Andrei Kislyakov<br />RIA Novosti political commentator<br />Moscow (UPI) Aug 04, 2006<br />People say that Russians and Americans are very much alike. Mentally, of course. Especially when we think of something big and impressive, such as a space effort. Sometimes, we copy each other's problems with mirror-like precision. Here is the latest example.<br />Until recently no one could doubt the prospects of Russia's reusable space transport system. For some years the Russian Space Agency (Roskosmos) has been talking its head off about the Kliper craft as the system's core. When early this year a tender was announced for developing and manufacturing a spaceship, it was a mere formality.<br /><br />Everybody knew the winner would be the Energiya Rocket and Space Corporation's Kliper project. Its features have been paraded dozens of times, its mock-ups have been on display at shows and exhibitions from Tokyo to Paris to Berlin. The fruit was about to fall from the tree.<br /><br />Also until recently we knew practically nothing of a similar American project. The Americans intend to build, under NASA's Constellation Program, the reusable Crew Exploration Vehicle (CEV) for missions to the International Space Station and, later to the Moon and Mars.<br /><br />Overnight everything changed. Late in June, speaking at the Farnborough aerospace show, the Roskosmos leadership suddenly announced that they were suspending the tender and would instead adopt a multi-stage program of creating a space transport vehicle. Now the main emphasis is on the time-tested orbital workhorse, the Soyuz spacecraft. On the American side, everything is tip-top and clear. They have even come up with a name: Orion.<br /><br />From elementary algebra we know that a linear equation like X + 5 = 10 can be solved when ther</p></blockquote>
