#20 On the guy who gave the 36 rocket Block Buy to ULA this just came out:Here's the link to the Correll story mentioned above: |

#19 Reminds me of my H2O Water Pump Rocket. I kinda favor the Giant Trampoline idea for launching and recovering payloads from LEO. |

#18 Squinty: I wasn't talking about the X-37, I was talking about a real RLV. A followup to DC-X, for instance. The X-37 is just another reusable payload. |

#17 XCOR Lynx appears to be in sub-orbital competition with Virgin Galactic. Sort of X-15 realm. Nobody outside of XCOR has a clue if it could go orbital and they are not saying. |

#15 It looks like the X-37 scales:Wikipedia: X-37C |

#14 Snowy Mountain, I was talking about budget wars back in the 1970's before Columbia was built. Today, the military has the X-37B. |

#13 Actually, Squinty, the military wanted to try to build an RLV (or many) back in the 90's, but the Clinton Administration moved their RLV efforts to NASA, where they were quietly strangled. The military got EELV, which turned into two expendable vehicles: one paperworked to death, and the other half-built by Russians, which is where we are today. Shipman: Have you seen the XCOR Lynx vehicle? It looks a lot like that X-20. |

#12 NASA screwed it up post-Apollo. They let the military dictate that the shuttle become a cargo truck, instead of a manned flight only system. As I recollect, NASA was trying to justify budgets by saying that the space shuttle could be a truck. Dumb, dumb, idea. Too dangerous for the truck drivers. The military was happy with its own cheaper unmanned delivery systems. After Challenger, the military went back to them. |

#10 And the cancellations actually go to Nixon and the Dems in Congress. |

#9 As for heavy lift: Think about a hollowed out Shuttle, sans all that crew space and equipment. Why not make a thick kinda like the X37B only jumbo sized, with higher sustainable G forces, etc (due to not needing to be man rated).You'd think that would work, re-using the SRBs, Fuel Tank, main engines, and much of the shuttle design with newer materiel and electronics. |

#8 I watched man walk on the moon in a NCO club in Quang Tri. |

#7 Dead-on Ship. Something like this should have been in space 40 years ago. Johnson wanted "the n****** (his words) voting for Democrats for the next 200 years", so that what we got. Plus Vietnam. That got the 3 Apollo missions scrubbed, and left NASA flatfooted. NASA screwed it up post-Apollo. They let the military dictate that the shuttle become a cargo truck, instead of a manned flight only system. Now it looks like heavy goes on its own, and manned goes on a less complex, lighter reusable platform. Should have been this way all along - put the heavy lift on a different (unmanned) launch platform, since its almost completely a different beast, aerodynamically speaking. Keep the manned stuff smaller, safer to recover, and easy to launch (think rescue). Gemini,Apollo and Skylab showed orbital rendezvous can be routinely accomplished between manned and unmanned space platforms. |

#6 Damn Great Society, damn Vietnam War: |

#5 Boeing built the X37-B which last time I checked was still in orbit. SpaceX will likely be first though with a man rated vehicle. |

#4 OS - they claim it's booster agnostic. Just that wind tunnel tests have only been done with the Atlas. Lockheed is building the actual airframe for SNC. Second choice of LV for the Dreamchaser is Falcon 9.1. Folks think it could use a Delta too if Delta ever gets man rated. Same for the CST-100 from Boeing. One of the optional upper stages on a delta is the same as the one they are spec'ed with on the Atlas. Delta's primary man rating problem appears to be older avionics. |

#3 Reminds me of my H2O Water Pump Rocket. I've got it around here somewhere. |

#2 VTHL Lifting Body = SNC's Dreamchaser Vertical Takeoff Horizontal Landing (q.v. Lifting Body) |

#1 Big issue is man-rated boosters even though crew transport module is getting the press. Space-X probably in the lead for the Crew transport module, but in terms of looks, everybody seems to love the SNC lifting body mini-orbiter. Its designed to sit on an Atlas-V. I wonder if it can be lifted by some version of the Space-X Falcon booster? |
