#228 Re: Interplanetary transportation » Ares V (CaLV) - status » 2006-06-16 13:46:02

CADB Kosberg has already offered to license production of RD-0120 Aerojet or any other interested American firm, and have always had a green light from the Russian government to do so. These are the current facts, past and present tense, not some prediction or assumption on my part. 

Interesting

Aerojet already has much of the technical documentation required to start pre-production of an RD-0120 copy.  Any US based RD-0120 production line would, by definition, be up and running well before the first CaLV launch

I have no pro-Russian/anti American bias. Chelomei, for example, is widely considered one of the greatest personalities of  the Soviet space programme. I consider him nothing but a vindictive political hack who contributed nothing useful to the field of spaceflight.  Proton was a total disaster for the 1st five or ten years, and it is unfortunate that this ultra-toxic monstrosity remains in production.

Well said

I think RS-68 is a fine engine. RD-0120 is even better.

Even so--RS-68 is what we have. Perhaps RD-0120 can come later. Perhaps China will want it. As far as politics (yawn) is concerned, Obey and Frank on the Left are just as much enemies of VSE as Mike Pence is on the right. So let's vote pro-space--without regard to party differences. In this era of 50/50 votes, small comunities (The Elian Gonz crowd in Florida--the Naderites, etc. --all have a power to tilt the balence. What we must do is to put aside our differences and show that space advocates can also be a voice. If Jeb's last name wasn't Bush--his pro-space stance alone might get Florida and Ohio, state with NASA centers. If he runs away from his Woodrow Wilsion brother inhabiting the White House--his center-right pro-space platform might have him win the Presidency.

This is one of the reasons why I think the Sea Dragon concept would fit well with NSWRs. Both the NSWR payload and the Sea Dragon booster need large amounts of water. We are already seeing "Spars" like the Neptune being up-ended in ocean that are as large or larger than Sea Dragon.

So, Sea Dragon--in a fashion--is already being built--as the Neptune Spar.

Space-elevators may use this tech as well

Very large nautical structures would allow very strong hulls that NSWR will doubtless need, plus the payload is only water.

A seperate launch of the actual nuclear material would be done out of baikonur.

Hujsak wrote a book calling for the large spherical tanks (that will be in production shortly for new LNG terminals) to be used for large, Phil Bono type craft. He called this craft a ULLV.

I think nautical firms may be the answer for very large spacelift.

#230 Re: Science, Technology, and Astronomy » Neptune Trojans » 2006-06-16 13:29:03

I wonder if anyone has tracked the path of the Centaurs like Chiron (or other bodies) to see if we have any perturbers to move through this region of space.

#233 Re: Interplanetary transportation » Space Elevator news » 2006-06-09 12:04:48

Newt Gingrich has already spoken out against NASA's involvement in taking humans to space, and has instead proposed a series of prizes to continue to encourage private enterprise to take over the fulfillment of that need.

Please--not that rot again. Griffin is an engineer--so where does that politico get off telling him his business? If you split money a thousand different ways you get a thousand different failures. Enough with the alt.space movement.

#234 Re: Human missions » SLAM » 2006-06-09 11:58:19

That is good for the future--but for starters, I'd rather re-use water and just keep sending more per mission to build up something of a stockpile. I see LUNOX propellant schemes--maybe even LSAMS at a later date, but I would settle for a nice large soft-landed tank to keep water in and build my water supplies over time--preferably in segmented H2O tanks to cut down on micrometeoroid loss. The water will freeze the opening shut, where hydrogen by itself is a lot harder to contain. Water is dense and rather inert.

With water and tankage delivered to the moon, you can make the most of the water for heating, cooling, etc. Bulk hydrogen can come later. As other missions land nearby. I want to see the tanks on the landers filled with H2O over time. As the ascent stage leaves, the stump of the base can be turned into some sort of still as you suggest. I want to see the stumps of the landers used as roofs with inflatable antennas and habitats place on or about them.

#235 Re: Human missions » Do you (exactly) know how to "man-rate" a rocket? » 2006-06-09 11:51:35

No no, I work for the CIA as a Deputy Subtrifuge and Disinformation Specialist in secret conjunction with the Lockheed Martin and Boeing corporations, honest. My boss is Clark, another board member, who sucessfully ruined the life of that genius Rick Dobson who sought to destroy Lockheed/Boeing/America's grip on space flight... he just had to have his credability broken and done away with.

Oh now I have gone and said too much

Nice job exposing Darleen Druyen though.  wink Those pictures of her in the buff with Janet Reno were a little tough to take...

#236 Re: Human missions » gaetanomarano Lunar Space Station » 2006-06-09 11:46:39

I don't have a problem with a lunar station, so long as CEV is nearby. CEV may need to dock to the station if it has problem with life-support. It is a payload for the future of course. The more infrastructure you have, the better.

#237 Re: Human missions » Calling our technical experts - Any chance this thing works? » 2006-06-09 11:43:39

It is only as good as the investors. That is the problem with space libertarian philosophy--in that you defend the capability of investors to say 'no.' Better to swallo some pride and cal for some tax money. Most investors would rather invest in Exxon than in space advocates.

Don't say I didn't warn you.

#238 Re: Human missions » a bigalow Mars Direct? » 2006-06-09 11:39:00

I know gene Meyers at SIG. Look, there were plans some years ago concerning passengers in the shuttle bay. He has let the Space Hotel thing slip and is more interested in large powersat demonstrators and has developed quite a few contacts. There was once a time that large numbers of folks were going to space on STS--before Columbia--so that isn't too farfetched

Bigelow seems more like a joke.

Gene is what a space start up leader should be. He wants to work with Griffin and VSE and find a payload for CaLV. That is where the alt.spacers need to focus. Let Bigelow fund a simple hollow tube for CaLV and have a simple hotel if he wants one. Perhaps that would be a good test payload for CaLV so if there is a mishap--you haven't really lost anything. Just a big tube with rooms and a soyuz dock on one end. That isn't too far-fetched.

#239 Re: Human missions » Alt.space debacle (GCNRevenger 's gonna love this) » 2006-06-09 11:33:30

Space-flight is blue-collar--not white collar. The model that works for internet gurus does not work for space. I want to see space colonies--and perhaps greenhouses--eventually. Right now, I'd settle for a bigger line of rockets. That has to come first--and the alt.spacers are bashing CaLV and VSE and offer nothing but hot air in return.

Spaceflight will always have more in common with TVA than MSN. You need real infrastructure--and it needs to be supported. Let the alt.spacers find payloads to place atop CaLV, so they don't have to re-invent the wheel with boosters. Musk spent a lot of money just to replicate an LV the ABMA threw together (Redstone class).

There is no Long-eze to orbit in the works--that has a chance.

So we should support NASA.

Private Enterprize has only one successful space program--China's. Every time you go to Wal-Mart, you help the Long March to space. So be it. But don't call NASA a socialist program when 'free-enterprise' money goes to Shenzhou.

#240 Re: Human missions » NASA Exploration Roadmaps » 2006-06-09 11:23:19

I can't get the link to work.

I really worry about the next administration. When Zubrin called for an HLLV, McCain rolled his eyes. (not a good sign).

McCain asked about a response to china, and one of the space libertairan frauds responded by saying that we don't need "one 'socialist space program to respond to another."

So Apollo was socialist and not a sign of the strength of the free-world.

That just shows the idiocy of the space libertarians who would no doubt nix VSE--while secretly getting NASA/taxpayer funds for a plethora of Rube Goldberg schemes--none of which will ever see orbit.  McCain worries me. Too bad Jeb's last name is Bush.

#241 Re: Human missions » Ion to Mars » 2006-06-09 11:16:45

CaLV/NTR

That is the winning combo.

#242 Re: Human missions » Engine Pod Economics » 2006-06-09 11:14:42

Enough with the re-usability crap. Build big and simple. A recoverable engine module will just add to costs.

HLLV--not HLV is what we need.

#243 Re: Interplanetary transportation » COTS - status » 2006-06-09 11:10:35

At least he is bending metal--I'll give him that.

Branson talks about spaceports where Musk is putting his money into actual hardware

I respect that.

#244 Re: Human missions » Human Mars Landing Mission for 2033 » 2006-06-09 11:05:32

Less assembly=greater chance of success.

CaLV should be just one of a line of larger LVs, with Rombus, Sea Dragon or Nexus coming 20 yrs afterwards. Thats how you assemble big ships--with big modules. CaLV for high value articles, Sea Dragon for propellant, tankage, etc.

#245 Re: Human missions » SRB booster for CEV » 2006-06-09 10:59:18

Good point. BTW Boeing no longer has RS-68--that's P&W now--so they have both engines IIRC.

In the far future, I hope to see the SRBs replaced by liquids with RD-180s or RD-170s at some point.

Here is a thought: Perhaps the CaLV could be called "Delta V" ("Del-ta vee").

What with five RS-68s and all, it looks like a big Delta. This way, Boeing can look at it as a family member and have less hostility towards it.

#246 Re: Human missions » SLAM » 2006-06-09 10:53:50

I don't know if I buy that. Sounds like more Rube Goldberg nonsense to undermine greater lift capability in LVs.

What do you expect from the white-coats and pointy-heads? I'll take a soft landing for my water supplies, thank you very much.

Let me shut off his running water and have him gather hailstones to drink and see how he likes it. And imagine how hard he will huff and puff without a suit. Or how much oxygen he would burn in the attempt.

Please...

#247 Re: Interplanetary transportation » Ares I (CLV) - status » 2006-06-09 10:49:11

There were plans for CaLV without the solids over at the ESAS Alternatives page at www.nasaspaceflight.com

CaLV will have many uses. I hope to see it used as much if not more than Titan IV.

#248 Re: Interplanetary transportation » Europe build a Heavy lifter ( 100 tonne Euro-HLLV ) ? » 2006-06-09 10:46:24

Ariane X (or Ariane M) CaLV--at least we are seeing more support of HLLVs. Maybe we can put fantasies of space elevators to bed now and finally support big, simple rockets for a change.

#249 Re: Interplanetary transportation » Ares V (CaLV) - status » 2006-06-09 10:43:00

She's lovely. Unlike X-33/VentureStar--this baby can fly.

#250 Re: Interplanetary transportation » Space Elevator news » 2006-06-09 10:40:14

It certainly would be. ISS proved the folly of piecemeal 20 ton at a time assembly.

I like the Mega-module approach--the one that was bashed by that know-nothing Ed Wright of the NASCAR rocket race scheme. The mega-module approach could have had ISS done in five flights--not five hundred, so to speak.

Bigger modules and less assembly. Not smaller modules and a whole bunch of headaches.
