http://www.space.com/12350-private-s...-nasa-shuttle-
retirement.html I don't understand why everyone's yelling that the U.S. space program is in dire straits now that Shuttle has retired. Sure, there's going to be a gap between Shuttle and new manned space systems coming online, but OTOH there's something beautiful at the end of the tunnel: commercial space aviation! Yes, people will mourn the demise of the spacious Shuttle with its proper toilet, whereas the Orion / Dragon astronauts will have to do their thing in a diaper (I'm pretty sure we'll see fewer women astronauts flying because of this). But in reality Shuttle was an unsafe death trap costing almost a billion dollars per flight and gobbling up a large percentage of NASA's budget. If we look at the commercial space companies in the race it looks like most of them have a viable system for LEO flights. Boeing was forced into developing CST-100 (by cheaper rival SpaceX) and may even pay for its integration with Atlas V out of its own pocket. But I'm afraid that subsequent flights will still be expensive (I estimate $200 million a flight minimum). SpaceX could fly at much cheaper rates but the company hasn't got many supporters (read: paid cronies) in Congress and may still lose the contract for ferrying astronauts to the ISS to Boeing. It's clear to me that Boeing is clearly doing everything it can to push SpaceX out of the market by blocking most venues where the company can have the greatest financial impact. It pushed its supporters to legislate the SLS (compare to SpaceX's $3 billion Falcon XX) and MPCV and will now probably do the same thing for crew ferrying to ISS. That would leave only the satellite business for SpaceX which Boeing already more or less ceded to foreign competitors (except for national security payloads). If I understood correctly it was Elon Musk's goal to shake up the manned space program, but there's a fair chance he'll be stuck with launching only satellites against budget prices. If he doesn't act decisively his impact on manned space exploration will be minimal. He's also taking big business risks as most of his contracts with NASA are fixed-price whilst Boeing is able to negotiate cost-plus for its already grossly overpriced gear and services. If one of his flights ends up badly he'll be risking his entire company. |

They've been around the block a long time, and they know what they're doing. Space X is starting from scratch. |

They've been around the block a long time, and they know what they're doing. Space X is starting from scratch. As a company they're starting from scratch, but they did hire quite a few engineers who *do* know what they're doing. *They didn't hire just newly graduated engineers with zero experience. *That would be awfully dumb of Musk. * Still, I know it will be an uphill battle for SpaceX as many of the entrenched conservatives in the business (engineers, contractors, and NASA) won't "trust them" due to their lack of a track record. *The conservative culture in this business insures that the Not Invented Here syndrome looms large. There is currently a bit of a discussion on the ARocket email list about how NASA is overly conservative with manned spaceflight and how the astronaut office goes right along with them. *There is great fear by astronauts that if they're outspoken in any way (i.e. not parroting what the rest of NASA management is saying) that they simply won't get a flight assignment. * The same can be said of NASA contractors. *If they become too outspoken, they simply won't get the contracts they need to survive. *This is a huge feedback loop which results in overly conservative approaches which risk little and consequently gain little. Jeff -- " Solids are a branch of fireworks, not rocketry. :-) :-) ", Henry Spencer 1/28/2011 Until Musk shows up on The Hill (and Rep. Hall, who's Chair of House Science and Technology Committee, has said he wants to have Musk as a witness), he's going to be viewed as a "rocket boy" or a "rocket hobbyist" by skeptics. Musk hasn't helped his cause any by saying that he'd retire on Mars. What he needs to do is shut up and let his rockets do the talking. Success is what will convince the doubters that Commercial Crew and cargo services will work. Not wild-eyed prounouncements from the CEO. But try telling that to the SpaceX worshipers/Commercial Space Fanboys/ObamaSpace worshipers over on spacepolitics.com....when it's pointed out that Congress has to approve Commercial crew and cargo funds from NASA, they either ignore it or assume Congress will fund it "as it's the right thing to do." The Commercial Spaceflight Foundation had a symposium a year or so ago, where this issue did come up, and the consensus was, according to Space News, "We need to stop talking and start flying." |

I'm not sure I understand the logic here. I mean how many pictures of Mars do you want right now? Here's one link alone to155,000. http://marsrover.nasa.gov/gallery/all/opportunity.html We can do better than just another 'reality' show, but from orbit. Space tourism will become the 'Concorde' of commercial space flight. If not the Titantic. Those first few flights will be risky and expensive, so also loaded with the rich-and-famous. We have to stop thinking in terms of what we can or should DO in space...mining or colonies or tourism. And start thinking about what kind of commodity that space offers us which we badly need. Stop exploring and start exploiting. There is only one commodity in low Earth orbit which makes any business sense at all. Space Solar Power! And the difference between the space tourism market, and the scale of the world-wide energy market, is on order of some five or six...zeros. Connect commercial space to energy, the second /largest/ and most important market on Earth, behind only food. If you want to grease the wheels for commercial space activity, it takes the kind of massive financing associated with things like nuclear power plants. Not jets. I think manned flight is really only justifiable for the military and the ISS. The pace of technology means robots can do just about anything else. And lowering costs to orbit means, first of all, unmanned. |

Space X is starting from scratch. ========================================== That's what Boeing will always yell: 'We put a man on the Moon!" But it's a nonsense argument. Most of the knowledge and experience of putting men into space or the Moon is freely available and engineers are mobile so Musk will have experienced Apollo engineers at his disposal even though his company doesn't have a track record (yet). SpaceX has already exceeded everyone's (including Boeing's) expectations and Boeing only last year started making moves against SpaceX with CST-100 and SLS. Before that they assumed that Musk would simply trip up and things would take care of themselves. But one way or another, Musk will have to get involved with manned rocketry, sending up satellites is simply not going to cut it. Eventually he could start some sort of Moon-flyby tour which could bring in big bucks. He could partner up with Bigelow to start a chain of space-hotels.

Stop exploring and start exploiting. WOW What mentality. Happily there is nothing to exploit in space (that's why the programs are shut down) And no, space solar power makes no sense since using solar power on the suface of the earth is much better economically that putting your arrays in space and have all kind of problems that you can avoid. |

For starters, doing it on Earth's surface is a lot easier and cheaper to do maintenance and repair on, particularly compared to a system deployed up in GEO, where you would have the radiation of solar storms to deal with. That not only would endanger any people working on them, but cause the solar cells to deteriorate with time. Pat |

That not only would endanger any people working on them, but cause the solar cells to deteriorate with time. Pat It's completely illogical to compare terrestrial solar to space solar. The large number of limitations of ground based solar provide an equal number of opportunities for space solar. They are complimentary not competitors, Space Solar Power can have all kinds of market niches ...all to itself. So it can charge what it needs to, it doesn't have to compete cost wise with any other source. Terrestrial solar can't....but Space Solar can.... Add power directly to an existing grid. Work at night or in bad weather. Be stored easily. Be transmitted long distances. Work far from the equator. Work in poor rural third world regions. Power disaster areas Power troops in the field Power satellites in orbit Power colonies on the Moon. Terrestrial solar has another limitation much like that of burning biomass.As we build more and more ground based solar panels, we cover more and more very expensive land. Crops can be grown under a rectenna however. Terrestrial solar isn't truly green or unlimited in potential as a result. Ask yourself, what was the reason AC power was such a huge advance over DC? It was simply out of the reason that AC could ...travel so much better. AC power transformed the planet. It directly benefited billions of people. That's the huge advantage Space Solar has over conventional sources. It can supply power to any place on Earth regardless of how temporary, rural, poor or isolated. 24/7. If the choice is no power or Space Solar Power, what do you think the response will be? And with laser transmission to the ground the one drawback of rectennas, their size, would also go away. Even NASA speculated a rectenna might someday be as small as the size of a ...car (hint). There is no other source of energy that is entirely clean unlimited in potential and in application. Only Space Solar Power can do all those things, making it the /only competitor/ in the race for a long-term energy solution for the entire planet. And once a Space Solar Power satellite is up and running, what are the costs of operation from that day forward? Does it need to have to pay for a constant stream of coal, gas or oil to keep operating? Which require hundreds of miles of roads and rail roads. Does it have operating costs which may triple in months every time some dictatorship falls apart? Does it require billions to take care of the nuclear waste once the power plant is worn out? All those advantages, yet everyone just says the obvious, it'll be more expensive....at first. So what? The first ANYTHING is always more expensive. Your criticism is a given. All that, while everyone at NASA and around here keeps moaning and groaning... "What are we going to do with our space program now"! "How are we going to reduce costs to orbit?" "What's the future for commercial space activity?" Sheez! I feel like I'm watching people groping hopelessly around in the dark for the light switch. IT'S OVER THERE .. Connect space activity to a market place where it can compete for trillions of dollars per/year, and win. While transforming the planet into a civilized place (sustainable = civilized) Space energy Inc But don't listen to me, listen to these guys, experts from your own field.
