" PM: If you were having a drink with astronauts planning to head for the moon in Orion, the new Crew Exploration Vehicle (CEV), what advice would you give them? ALDRIN: I&amp;#039;d tell them to look out the window, have a good time and make sure you know what to do if something goes wrong. You have to prepare for contingencies. PM: Like what? ALDRIN: One problem might be loss of communication, in which case you&amp;#039;d have to do your own navigating. We took a manual sextant on Apollo, and I&amp;#039;d advise Orion astronauts to carry one, too. They also need to make sure they have a good procedure for a free-return trajectory [in which gravity would carry the spacecraft directly back to Earth]. PM: How about the lunar landing? ALDRIN: You&amp;#039;d better have a full abort-to-orbit capability, plus rendezvous, like we did. And you need a contingency plan in case of docking problems on the return. If you can&amp;#039;t dock, you&amp;#039;d have to do an extravehicular transfer. That&amp;#039;s a pretty dicey affair, especially if the CEV is orbiting unmanned.  style=&amp;quot;float:right; margin-left:5px; font-size:9pt; font-weight:bold; border:thin solid #666666;&amp;quot;&amp;amp;gt;Mission: MoonMission to the Moon: How We&amp;#039;ll Go Back and Stay This Time How It Works: Diagram of NASA&amp;#039;s New Moon PlanWill It Fly? Podcast w/ Aerospace Engineer Rand Simberg Lunar Real Estate: NASA&amp;#039;s Permanent Moon Base PM: One thing about Orion that will be different from Apollo is the skip re-entry required to land on U.S. soil. ALDRIN: I&amp;#039;d be a little concerned about a skip re-entry. If something goes wrong and you land in water, is the Navy out there to pick you up? PM: What&amp;#039;s your take on NASA&amp;#039;s plan for a permanent moon outpost? ALDRIN: It&amp;#039;s hard to see the pitfalls so far ahead, but I worry that once we establish a base on the moon, we might get bogged down there. The way I see it, commercial interests should manage a lunar base while NASA gets on with the really important task of flying to Mars. (Photograph by Chris Buck/Corbis Outline.)
