#176 Re: Human missions » hot damn! Bigalow is up there! » 2006-08-11 16:16:13

One of the reason I do come to this website is to see GCN rant. He has the ability like no other to poke holes at Alt.space ventures and make it funny.

He does at that. One thing I will say for Bigelow is that his craft is more of a true spaceship--even in its stripped state--than Rutans. He has something of his own in orbit. I'll give him credit. He and Musk and Kistler have Hardware. I respect that.

I respect GCN as well. One of the reasons I wish Buran had been our STS and vice versa is that:

Space station freedom would have been done as megamodules.

Buran might have been returning bulk loads from 100 ton free-flying space-maufactur-pharma firms.

A gov't demonstrated market in a new medicine with great promise would have encouraged the Primes to invest real money--as opposed to bored millionaires with just enough money to get them into trouble, and broke.


That is one reason I want heavy lift and a gradual increase in the size of rockets to get some real facilities up there--cost-benefit be damned. We need a real beachhead and ISS aint it. It is 20 tons at a time too slow.

Gov't must lead the way. Once interst can be garnered then private business will follow along a respectable scale.

We got container ships thanks to Brunel and the Great Eastern--not to the America's cup and yachts.

Remember that.

Like here, the scientists play second fiddle to the military.

Sigh.

#178 Re: Human missions » NASA Exploration Roadmaps » 2006-08-11 16:12:50

Naming these babies Ares gives a strong message of where NASA's vision is headed eventually, IMO.

I like it a lot, this is what every Mars-nut could only dream of, some years ago, and now...

Wow, looks like we're finally heading out of LEO, for real, yay!

So let's show some appreciation and start up a webpage supporting Mike Griffin? Lots of Signatures.

Friedman and Tumlinson have their mouthpieces--I say we turn this site into a couter against the idiots like Cowing, Tumlinson Jeff Bell, etc.

Who's with me?

#180 Re: Human missions » Be your own satellite » 2006-08-11 16:01:25

Rational self-interest is okay and everyone's selfish to a point [some of which is tied in with the survival instinct]; some selfishness can be beneficial.  But this?  It's over the top, tacky and ... disgusting.

Spoken like a true socialist smile

Socialism doesn't work by the way, if you limit what people are allowed to do for their own self interest, no matter how selfish, you remove their drive to be productive so that they can earn money to enjoy themselves. It ruins everything, and causes more poverty than it eliminates.

I'll split the difference. Farming is best done by private companies--but spaceflight is best done by gov'ts who understand infrastructure. A lot of cyberlibertarians get their electrical power from TVA after all.

My problem is that both the Left and the Right have gone anti-industry due to the influence of Greens on one side and outsourcers on the other.

With tax-breaks against illegals voting themselves more of someone elses money--the best and brightest go wanting.

ironically--if an alt.spacer were to defect to the DPRK--he would never have to beg for funding ever again. Yes, he is just as apt to get shot at any time.

Then too--if he asks for a roll of steel--he gets it. He might have the power of a chief designer if he has Kim's favor.

We saw Gerald Bull get ignored by both the DNC and GOP--and he went to Iraq.

Who knows--a space start up might head for North Korea.

Now that's a chilling thought--and one more reason technocrats need to run the USA for awhile--and not Greens on one side and Blue-bloods on the other.

#181 Re: Human missions » Nasa Shuttle, ISS Woes & To-Mars » 2006-08-11 15:54:00

I'd like to see Energiya brought back--by non-NASA fund. I think the oil states should invest in this.

Wasn't there a suggestion from the State Dept. urging Boeing to go on a fact finding trip?

(They were too busy selling Delta IV).

#182 Re: Human missions » CEV is Bullshi... » 2006-08-11 15:49:58

I have no problems with the crew riding Ares V.

#183 Re: Human missions » Is the 'VSE' getting dimmer ? » 2006-08-11 15:41:01

And I agree with Redsteak (and probably M. Griffin too), that no AltSpace commercial outfit - none - have shown credible competance to provide even basic ISS cargo services with their own technology.  As Griffin said, NASA simply can't be forking over nine-digit sums of money to AltSpace companies with no strings attached and low certainty of success.

The only thing the SFF says in this article is that they believe NASA is doomed unless they prostrate themselves to the AltSpace community, who save for the dinky Falcon-I have not shown that they are up to the task.

Most of the "fact hiding" has been from Congress when M. Griffin has sucessfully killed SSME and scaled back reliance on uneeded/expensive/incompetant NASA centers in various states.

Very well put. I cannot stand that fraud Tumlinson.

#184 Re: Interplanetary transportation » COTS - status » 2006-08-11 15:37:53

Their big investor walked out on them. That is the number one failing of the alt.spacers:

--the questionable nature of the bored rich; like that tax cheat Anderson for one.


Spaceflight is too important to be left up to the whim of the Bransons.

#185 Re: Human missions » Space-X's baby lost to human error? » 2006-08-11 15:34:17

There is a reason behind the two-man rule after all.

What was the bad nut's name? Cowing, Tumlinson, Bell or Friedman?

#186 Re: Human missions » Reducing Costs - Changing the Human Centric Space Approach » 2006-08-11 15:31:21

Interesting, that the Kistler people relied on government-developed rocket engines, the venerable Russian NK-33. They wouldn't even be in business if they had to develop their own engine.

Very well said. Those engines have been sitting around an awfully long time, too.

#190 Re: Interplanetary transportation » Ares I (CLV) - status » 2006-08-11 15:24:00

sigh

Marshall Spaceflight Center needs six years to build an engine that we already have much of the design for?

Note that Marshall would have been awarded the contract for the CEV-SM/LSAM-acent methane rocket, which was canceld since they didn't seem to be up to the task in any reasonably efficient way... These guys sound, well, incompetant to me.

You have to understand that Marshall has been poisoned by the Goldin age, where the fans of big rockets like Bill Eoff were considered personal non grata--with the X-33 frauds running the show. If you believed in big, simple rockets--you weren't welcome. We are still picking up the pieces--and the MSFC bashers are exploiting it.

#192 Re: Interplanetary transportation » Followup on the Heim Drive » 2006-08-11 15:17:02

150 tons from the surface. It would be nice.

#193 Re: Interplanetary transportation » China eyeing new HL - Agency Expecting approval this year » 2006-08-11 15:10:08

At least for now.

Back to the propulsion/fuel debate. Liquid Hydrogen weighs 16 times less than LOX and lox is rather cheap in comparison. The the cost of hydrogen is less. With hydrogen you need big tanks--but that is no loss what with better volume to weight.

For spaceplanes however, you need a dense fuel. And for them--I think hypergolics are best. You have a compact airframe that way. The greens won't like it though.

Martin Astrorocket needs to be looked at again, in about 50 years when we get even better materials.

#194 Re: Interplanetary transportation » Ares V (CaLV) - status » 2006-08-11 14:59:33

Note the magic words...: "Word has it"

Say this little birdie chirping in NASAWatch's ear is a liar trying to stoke the few people who care about space - us - into a furor.

Probably so. Some ATK basher that couldn't foist the EELV albatross on Griffins neck.

#196 Re: Interplanetary transportation » one reason nuclear propulsion may be ok'd » 2006-08-11 14:39:28

It may be that the only way to get space funded is with a project that can serve both--say an LNG carrier with a reactor to get free hydrogen and oxygen for propellant and sell more as a way to sustain spaceflight.

If you want to get humanity into space big time--you cannot use space as an actuall money maker at first. Sell fuel for a profit and put that money--and your free fuel--into big LVs

A state sponsored hydrogen-filled LNG carrier with a reactor might need more room. Large tubular barges in the shape of the Neptune Spar, perhaps... wink

#197 Re: Interplanetary transportation » Project Noah (Big cousin of Project Orion) » 2006-08-11 14:34:35

Orion will cost a lot more. Sea Dragon is simple by comparison. It is small compared to the Troll platform which cost around a Titan IV launch or two to build.

I agree. I kind of see it like this. We may in the near future develop a cheap method to get to space or utilize existing launch technology to establish a good foothold in space anyway. However, if we don’t the colony of the future could be built on earth. I agree that the complexity of the enterprise is massive but keep in mind that Cathedrals were built over multiple generations. If people believed in something enough they would devote their resources. So if you could convince people you could build a vehicle robust enough to survive several generations with reliable enough engineering that it will work the first time then there is a chance people would devote resources to it. Even if we get to space by other means there may be no cheaper way to build an Orion propelled colony then right here on earth.

Thank you. Orion was said to work beter the bigger it got. BDBs are that way too, in that as the cube goes up the surface area goes up by the square. At a large sixe with a lot of propellant--Sea Dragon hulls can be thick by human standards but thin in comparison to the whole vehicle.

On one board--someone proposed putting an Arktica sized reactor on an LNG ship that must carry supercold liquids in any event.

You get your propellant for free--and when not launching--you sell hydrogen in place of natural gas.

#198 Re: Interplanetary transportation » Sci-Am on COSMIC RAYS Stopping Deep Space Exploration » 2006-08-11 14:29:58

I agree. The author of the Sci Am article are probably anti-human spaceflight hacks doing their dirt with their chosen facts.

#199 Re: Interplanetary transportation » Using the shuttle's external tanks as spacecraft » 2006-08-11 14:25:23

I would not say its no good for housing. Skylab was to be wetstage. Ares V with a small payload remains attached to a foamless ET with another type of covering perhaps--and the two habs linked. Ares is very nearly stage-and-a half--so it can keep its attachment to the ET. Extra room. Soyuz docking allows tourists to use the simple side. An empty shell is good for just flying around.

Mark Holderman of JSE sees them as use for GEODEs.

Sea Dragon upper stages are rugged enough to be immune from most debris and they would be good liquid tanks being overbuilt.

#200 Re: Interplanetary transportation » Using lift with beamed propulsion. » 2006-08-11 14:22:47

I wonder if beamed energy propulsion might be a good fit with an Airship to Orbit concept. First to power ion wind and then to push it up.

I might launch the ATO bigelow fashion atop Ares and coat it with  some UV material to give it a super thin shell.

it my be that Leiks craft is the only way to us beamed energy.

Frankly--its best to just stick with big rockets.
