You make it sound as if Teledesic and Iridium had built and tested all their satellites and had them sitting in a warehouse somewhere waiting for a launch opportunity. Their ability to build satellites far exceeded their ability to launch them. Are you asserting that Teledesic and Iridium's time to market was negatively impacted by their inability to purchase launches in a timely manner? Yes. *If so, what evidence do you have to back up this assertion? Personal discussion with the principals involved. Satellites take quite a bit of time to design, build, and test before launch. True. *You can't just pick one off the shelf of your local mega-mart and launch it the next day. No one's saying that. Lead times for launchers are 7 years or more. Lead times for satellites are 3 years or less. Hughes Aerospace tried to shorten that by creating common core elements like the 601 frame, etc. This lead time lag along with the high costs involved reflects the inefficiency of the aerospace supply chain and the way missile technologies are controlled by the Department of Defense. A five year acquisition and development program could streamline all of this and radically transform our relationship to space. It would also spell the end of the US Missile Control Paradigm. *As long as the lead time on a launcher is less than the lead time for the satellite, the lead time for the launch vehicle is completely and utterly irrelevant. True, but as I've said, the lead time for commercial satellites are 3 years or less. The lead time for ELVs are 7 years and more. Hughes believing the BS put out about the Shuttle before the first shuttle was launched bet heavily on building a satellite supply chain and lost back in the 80s. I told Bob Forward and others at that time that only an integrated supplier of truly reusable low cost launchers that also supplied satellites in time frames of 18 months or so, would bring about the sorts of advances in space communications and other off world assets we see is common in industries like consumer electronics.

Unfortuantely, I'm on a beach in New Zealand in a caravan with very limited bandwidth. I'm looking at sites for a new hydrogen supply chain I am building to re-start Huntly Power Station and start (finally) Marsden Point power station - both as clean hydrogen burning power plants. We will also use hydrogen to turn stranded coal that's no longer burned to supply 1,200 MW of power to thousands of barrels of petrol per day - made in New Zealand. Anyway, if I had the bandwidth, I would search through the excellent papers done by MIT and Harvard business graduates that have studied this problem. Of course, its my discussions with folks at Motorola and Teledesic at the time that made the problem obvious to me. I will be back at my beach house in Christchurch (Sumner) and will look up stuff then when I have the time. |

Jeff is actually a NASA/DARPA kinda guy, whereas anything they do or don't do is perfectly fine and dandy by his way of thinking. So, no matters what the delay or cost overrun makes no difference whatsoever. In other words, if our NIF accomplished their goal of fusion energy in 20 years and another trillion dollars from now, so be it as far as Jeff is concerned. ~ BG |

In article c2d1643d-7f75-405d-a478-
, says... Jeff is actually a NASA/DARPA kinda guy, whereas anything they do or don't do is perfectly fine and dandy by his way of thinking. B.S. I was against Ares I and Ares V from day one. Ares I, in particular, was the stupidest idea for a crew launch vehicle in the history of manned spaceflight and I'm happy to see it die! I've been a supporter of commercial cargo and commercial crew to/from ISS from day one as well. It's time to get NASA out of the "routine" part of spaceflight, which is to and from LEO, so HOPEFULLY NASA can focus on bigger and better things, like developing in space refueling technologies, aerospike engines, and etc. NASA needs to be reformed into a more NACA like agency. It should be developing the technologies which enable commercial space to thrive. It should not be in competition with commercial space. It needs to get out of the way of commercial space. That means I really don't want to see any more NASA developed launch vehicles. Unfortunately, US politics says otherwise. Jeff -- 42 |

I agree, but I still don't think lead times on launch vehicles is the huge bottleneck that Mook is making it out to be. Everything I've read says that Iridium had other *huge* problems completely unrelated to launch vehicle availability. Jeff -- 42 |

Jeff -- 42 Mook always makes something seem bigger than it is, but he means well and isn't always systematically wrong because of how he thinks we should advance. Of lower cost and much environmentally cleaner launch capability that's reliable and reusable as possible would have greatly improved the private/commercial utilization and exploration of space, especially on behalf of private LEO space stations and of the Clarke Station and/or that of my LSE/CM-ISS (Boeing OASIS and many other Earth-moon L1 considerations as of decades ago). Long before now we could have had a Venus L2 space station as our cool outpost/gateway. It's hard to fully imagine how much better off we'd all be without a public funded NASA that has no intentions or incentives of ever sharing technology or showing any break-even, much less an actual profit (aka return on investment). Now we're out of time, as well as worse than broke, and China as well as India are about to leave us in their dust. ~ BG |
