A robot is as only good as the purpose you want it to do.

A robot is only as good as its launch vehicle.

What kills me is how the robotics people will howl about how VSE will 'steal' money from science forgetting that the LVs we get out of the bargain will be superior to that Delta II crutch which forces people to drop science packages anyway due to mass constraints imposed upon them by Launch Vehicle development (or the lack of it)  that the robots-only people have no interest in forwarding.

This was why The Planetary Society got chumped. They focused all their energy on advocacy and the payload--and got bit in the tush when the Volna flopped out on them not once but twice.

The Foton materials sat is based on the old Vostok hull which came as a result of human-centered space-flight--without which you don't get robot probes either. The new Venus craft is going atop the R-7--made by Korolov as more of a human-booster sold as an ICBM due to heavy warheads.

If it were up to the military--our largest rocket would be the Minuteman and the Russians' would have been Topol-M, neither of which could have launched Spirit and Opportunity.

We have focused too much on payloads at the expense of the rocket. It's time for the robots huggers to know their place. They might hate Griffin now--but when they have the Stick and HLLV--they will be grateful that they can kick that miserable underpowered Delta II to the curb.

You are quite right. Lockheeds CEV is just another SLI/OSP rehash they are using to get some Air Force attention. Let the russians have their Kliper--and we will stick to capsules. That beats us all doing the same thing.

I'm talking about how we see people running out of ideas for names; three Falcons, two Ares, etc.

It could make research confusing for newsmen who cover space stories--and could lead to even worse reporting on space issues. Most newscritters aren't that bright to begin with.

The launch vehicles have to come first anyway. JIMO just kept getting bigger.

I think it is a tossup between GCNR and NSWR. The former is probobly a little harder but would be safer and more conventional. The latter is different then anything before it, and the fuel would be "scarrier" to use.

The latter would be simpler. Fuel injection technology is about as simple as it gets--the starship equivalent of a diesel with glow-plugs.

#508 Re: Interplanetary transportation » Rocket Monopoly - United Launch Alliance » 2005-09-16 12:57:54

There is a schism. Some in USA want shuttle derived--but the suits like ULA a bit more because they can get NASA to pay for their EELVs that are not selling well.

Griffin seems to have won his push for HLLV--but I would still expect him to be undermined. It's all politics.

:arrow: Failure analysis for welds:
http://projects.battelle.org/verity/default.aspx

In the early 90's, Battelle scientists recognized the need for a reliable stress analysis methodology that would address the known problems encountered in conventional finite element analysis procedures for welded joints or geometric discontinuities within structures. Consequently, Battelle created, developed and validated a new patent pending methodology known as the Verity™ mesh-insensitive structural stress methodology. Although initially viewed as "too good to be true" or "too simple to possibly work," Verity™ has now been validated by leading industry experts across a broad array of industries.

Look at the shuttle derived chart here:
http://www.astronautix.com/lvfam/shuttle.htm

Now click on Zubin's Ares and you will get this instead:
http://www.astronautix.com/lvs/ares.htm

So there are three Falcons and two Ares.

#512 Re: Interplanetary transportation » Rocket Monopoly - United Launch Alliance » 2005-09-14 13:12:35

Delta II was to be the fall guy--the sacrificial lamb. And that was before Falcon IX

If (and that is a big if) Musk's rocket is successful--and he chunks his 'reusability' aspect--Delta II will be finished. If it flys--it will give ULA something to worry about--and Griffin--if he stays past Bush's Presidency might just use it as leverage.

Falcon's big competitor will still be Ur-100/Dnepr--though Musk is even knocking on Proton's door with Falcon IX. So ILS will have some cheap competition.

But Falcon I hasn't launched yet. So it is all up in the air--or isn't.

#513 Re: Interplanetary transportation » WARP DRIVE, AHEM! » 2005-09-14 13:05:56

I think we'd have to have zero point to do that. I'm not holding my breath.

I'm more of a nuclear thermal advocate:

Bimodal systems can supply electrical power as well.

#516 Re: Interplanetary transportation » WARP DRIVE, AHEM! » 2005-09-14 12:34:31

About the best we can hope for (I hope you are not eating) would be Zubrin's Nuclear Salt Water Rocket and its 1g thrust.

The heating is going to be an issue--but it is a smoother ride than Orion.

#517 Re: Interplanetary transportation » Rocket Monopoly - United Launch Alliance » 2005-09-14 12:29:06

That was just LockMarts warmed over OSP proposal under the Marshall make-work program. They even had a dot.com name www.slinews.com

Why Marshall had that was anyones guess. More of Dennis Smith and Dan Dumbacher. Now DARPA is still trying to bring X-37 back to life. Griffin has no use for such designs.

Back on topic--

ULA in trouble:
http://yahoo.reuters.com/financeQuoteCo … 616_newsml

I think this is funny.

With Falcon IX as a bargaining chip and the OSTP joint requirement letter now signed--Griff can threaten ULA with all-Falcon VSE missions unless Boeing/LockMart use their lobby-power to support HLLV.

Delta II has had it.

The likelyhood of a nut even knowing directed energy weapons exist is low--let alone getting one.

Then too--there is the book.

The Poor Man's Ray Gun

You can make it with the magnetron from a microwave.

#519 Re: Science, Technology, and Astronomy » Shields UP! - Star Trek Like Shields » 2005-09-14 12:18:13

I think they have transparent concrete--which would be a good matrix to put shielding material in.

#521 Re: Space Policy » www.whitehouse.gov » 2005-09-14 12:14:51

www.whitehouse.gov Write the President and tell him to give Griffin what he wants--and not to use Katrina as an excuse to cut NASA

#522 Re: Single Stage To Orbit » Realistic solutions to the difficulties of SSTO? » 2005-09-09 14:28:38

I thought DC-X had promise as a demonstrator--certainly as a lander. Place that atop the Magnum/Longfellow SD HLLV with four SRBs--and there is your direct ascent NOVA mission to the lunar poles right there.

You know the X-33 VentureStar was actually a J. Northrup design? He kept getting his cough-drop bottle confused with his suppository bottle at the home--with interesting results there at the home. So he took his bic lighter, and fused up a lozenge that was half cough-drop--half suppository. He put one hybrid in each hole so he knew he was covered.

But he put them all in the full bottle--which he threw away thinking the empty bottle had his medicine--and he died.

So some Lockheed-martin spies saw one of his lozenges---and that's where they came up with the VentureStar /X-33 design. They then tried to take it to Marshall--but took a wrong turn to the Alabama group home for retards.

"UH!--we use composite tanks for hydrogen, and leaky as a sieve engine...drool." 

And you know the rest.

My plan for the SSTO problem?

Get all the engineers who support it.

...line them up...

----and have them shot.

problem solved.

Now let's get back to Heavy Lift--something we know works.

#523 Re: Human missions » 4Frontiers » 2005-09-09 14:15:16

Public outreach? That won't help anything. People are either already interested or they are not. The best policy is to see if a law can be passed to have a 'Space Day" holiday where every channel must be forced to carry some NASA story.

That or my 'blackmail the congresscritters' idea.

It beats playing house on Devon Island.

No--it is a statement of fact--lamenting how bomb-disposal robots and 100s length Thors that put two metric tonnnes less in orbit than 50 yr. old R-7 are helping to nickel and dime NASA to death.

Yet more Goldin era stagnation.
