The Falcon V is certainly a Delta II replacement--and Dnepr is its closest rival.
Comsats continue to grow larger however.
Robert makes good sense.
We have become our own worst enemy--and the anti-space people like Matt Drudge and other love it.
it's time to support Mike Griffin and quit backbiting him.
It was part of the agreement. Nickels and dimes do add up. Not ISS/STS level--but it is one of the thousand cuts:
http://www.thespacereview.com/article/421/1
You really don't want to go to Mars, do you? We have a wonderful opportunity with George W.'s VSE to get out of LEO and start exploring space again, but the trap is to get stuck on the Moon. If lunar equipment is not designed from the beginning to be Mars equipment then Mars just won't happen.
Edit: Don't forget, that just about every penny spent, every pad modification, and engineer man-hour on Shuttle-C is spent on a booster that is too small for Mars and too small for efficent Lunar expeditions. I think it is safe to say that building the Shuttle-C is a step backwards away from the Moon or Mars.
Money spent to build a simple heavy launcher will be more than regained by preventing 3 years of shuttle operation and stopping the construction phase of ISS.
I started this thread to call for unity and a cohesive plan. Hacking and slashing existing assets will not get you to Mars. Destroying multi-billion dollar space projects would simply tell congress that NASA is too irresponsible to be permitted another multi-billion dollar project. You are arguing against Mars. The first thing you have to prove to congress is that you can be responsible with the assets already paid for. If you're not responsible, you get nothing! If Shuttle wasn't so old I wouldn't call for it's demise either, but it is time. ISS isn't even complete yet, hasn't even started operation. I'm having trouble staying calm; you just don't get it. The alternative to rapidly completing ISS to to drag it out for the full duration. If Atlantis launches in September and if they get another launch in 2005, and if they can maintain 6 launches per year it will be spring 2009 by the time it's finished. Delays are bound to happen which is why 2010 is the earliest retirement of Shuttle. The current budget shows costs for Shuttle jumped up from about $5 billion per year to $7.5 billion for return to flight, but after it's budgetted to remain at $7.5 billion. Chris Shank said they cut several programs to pay for RTF. With on-going shuttle operation increased to that level they won't have anything left for an inline heavy launcher. That means the heavy launcher won't start development until 2010. Initial design work for Saturn V started in 1959, and the F1 engine in 1958, Apollo 4 launched an unmanned test of the Saturn V in 1967. An SDV should take less time but a major redesign like the inline vehicle will take time. That really will mean the first manned mission to the Moon in 2018. I expect all hardware will be dedicated to the Moon, not at all usable on Mars. That means another major project and starting over again for Mars. After spending all that money on the Moon, politicians will take a hiatus before proceeding on to Mars. Even the inline SDV heavy launcher used for the Moon will be old and decommissioned by the time they get around to Mars. That means starting everything over again. How many decades? Will there be a manned mission to Mars within our lifetime?
I agree with most of what you say--but the robotics missions also have to go. HLLV needs all the friends it can get. Let its enemies enjoy Rutans fantasies and Ayn Rand nonsense.

I keep hearing rumors about five meter upper stages for Proton, Ariane...
Any images of the Parom tug from www.spacenews.ru ?
With the four SRBs--it will be able to Loft 160 tonnes--so there is a mars ship right there. The missile guys don't like SDV--they don't want anything bigger than Minuteman III. I for one am quite glad the HLLV crowd is getting respect.
Prometheus was to be a nuclear electric contraption--look at the cover of the recent Ad Astra mag.
There was some talk in Infinate Energy about Un-matter--not quite anti-matter because the neutron was regular matter somehow.
Doubt it.

The problem is that Griffin cannot cut as much as he would like. The 'we don't need to cut science missions crowd' is the problem. Mars isn't going anywhere--and as long as we nickel and dime NASA to death with one itty-bitty Delta II flight after another--neither will NASA.
We have focused too much on payloads and not enough on the rocket. I love the in-line SD HLLV, and it has to get money from somewhere. Rove has signed on--and a lot of the Solid South is made up of space states. Griffin wants to cut shuttle but cannot because it would make too many enemies.
That crutch of a Delta II has to go.
Delta II is the sacrifice.

"That was then, this is now. Money is already spent so destroying it will not save anything. The only logical solution is to complete it quickly... That means the long duration life support system for Mars must be tested in LEO where failure means dumping out back to Earth. Testing a long duration life support system for 26 months or more means a space station. Scrapping this station just to build another would cost a hell of a lot more."
On the contrary, ending our involvement with ISS and Shuttle would save tens of billions of dollars over their respective remaining lifetimes! Thats real money, money that could go to further the cause of human expansion into space... wasted... and for what?
I agree. Shocking!
At least we would have an HLLV if Shuttle and ISS were to die.
I still think it would be best for rocket tubes. A cheap way to apply solar panels in space. I don't think it is elevator material yet.
No getting away from the rocket.
Beats going straight into the ocean.
But you are right. Moon missions using assembly of smaller payloads are foolish.
Which is why I support SDV HLLV after all.
Some advancements--but they will still need big rockets to put up the material

Now--I still think we are a long way from SE--but this will certainly be a useful product.
Very cheap Solar Cells--Graetzel Cells could be a possibility.
Revenger is right. The nice book (Project Orion) explains that nuclear pulse units need to be custom made--canister like nuclear shaped charges to focus a 'plate' of tungsten or plastic even at the pusher plate.
Nuclear Salt Water Rockets can give a steady 1-g thrust--but have heating issues. Compared to these challenges--Sea Dragon is easy--and gets you about as much in orbit. Questionable:

That is where we disagree. The big tanks make perfect sense due to volume. The infatable designs cannot resist thrust and are good only when stationary--this ET hulls can--if done in the orginal wet-stage Skylab style--make for better exploration platform. Just One ET would give astronauts a lot of living area--and the ET could be surrounded in an inflatable structure--therefore any astronaut that would go to the outside of the tank would still be under the blanket if you will--eliminating the hazard of his floating away.
This way--if budgets are reduced even more--we still have one good sized cycler segment--even if ferry craft sent to service them are cramped EELV-launched craft.
I like a sturdy Sea Dragon hull even more--but that is another thread.
You wouldn't need very many for a durable station. In the era of Kansei, Three Gorges, the Burj Dubai skyscraper--and Troll--it is actually modest--and simpler to build than most ships. MLLV would carry more--but would have cost more.
Sea Dragon used cheaper shipbuilding tech at least.
A very light sail could open up its orbit--leaving the Zond-like craft to come back in a more direct fashion. The small sail could be put in a cycler orbit.
Anything but those cramped Volnas

You know that makes me happy. Griffin has won this round.
But a blood sacrifice must be made:
Delta II became a crutch--being a lot like fiber to keep you regular. It was not even based on an ICBM but on an IRBM. You have a Pershing/Jupiter/Scud class Thor that was just stretched--and it still puts two tons less in orbit than 50 yr. old R-7. HLLV is the battered womens shelter--it means a new way of life--but a better way of life. Delta II is the familiar guy in the wife-beater shirt. He fastens you up in a small, cramped space--he limits where you can go and what you can do.
But it looks like the cops have finally shown up:
http://www.space.com/spacenews/050704_b … onday.html
Excerpt
Griffin said he told Lord that NASA would be willing to switch to the medium-lift variants of the EELVs to loft its science spacecraft “provided that there is not an undue financial penalty for NASA.”
That might spell the end of Boeing’s smaller but highly reliable Delta 2 rocket, which has served as NASA’s primary workhorse for the past decade or more. That vehicle is no longer in the Air Force’s plans.
Griffin called a switch to EELV “the most nascent of plans” noting that NASA still has about a dozen Delta 2 launches under contract.
A Defense Department official, who asked not to be identified by name, confirmed that Griffin and Lord had reached a tentative agreement on Delta 2 and said that the Air Force is not likely to stand in the way of NASA developing shuttle-derived launchers.
Bad Boys, Bad Boys--whatcha gonna do...
More on the Death of Delta II:
http://www.thespacereview.com/article/421/1
"Above all for the people at the Pentagon, this “ceasefire” means encouraging NASA to give up on its traditional favorite, the Delta 2, in favor of the more expensive and capable EELVs. For many deep space missions this would mean more and better instrument packages and more propellant, which could in turn mean better overall scientific return on investment. Smaller missions could still be flown on Orbital Sciences Corporation’s Taurus or Pegasus launchers or on SpaceX’s Falcon 1 and 5, but the Delta 2, which has been the space agency’s workhorse, will be put out to pasture."
Don't get mad...the latest Mars mission will ride Atlas Centaur--the first NASA probe to use that rocket since 1978. If you will recall--they were able to put extra propellant in MRO due to greater lift capability.
I'd love to have the Delta II tooling so I could stomp on it and throw it in the river.
The author of the linked to article did botch it once:
"If they decided to build a SDLV with a side-mounted pod that fits where the shuttle orbiter is now attached, they could have something operational much sooner and with a lot less investment, but only the “stick” would give them the long-term very heavy-lift capacity they will need to economically lift the equipment needed for a permanent Moon base. "
The in line HLLV is Magnum/Ares whatever. The LEO-only CEV-atop-SRB is the stick--not HLLV.
Some nice work on HLLV and the stick is seen here if you scroll down:

One drawing doesn't make sense:

There the aft interstage is behind the SSME. It looks to me like the aft interstage would be behind the aft skirt--with the narrow end tapering into the thrust structure with the SSME coming last.
Oh well--maybe it's supposed to be a shroud. We need better art from Frassanito & Asc.

Discussion
http://xprizenews.org/forum/viewtopic.php?t=1409
So they will place a full-blown Soyuz on a simple circumlunar mission.
I am thinking that the orbital module will still be shed before the craft comes back to Earth--looking pretty much like ZOND upon its return at least.
So I would like to hear some suggestions on what you would like to put on the orbital module that will be left behind near the moon.
I am thinking that this price tag is too steep for all but billionares--but if some instruments were placed aboard the module--and if it was left in orbit--I dare say some of the cost might be defered as universities chip in. The tourist and cosmonaut would be able to work on projects not to be trusted to robots until after deployment at least.
Here is one other thought. This might even allow for a spacewalk high above the lunar surface.
If the orbital module were filled with a solar sail--with a tube left for a suited cosmonaut to use--a solar sail could be deployed by such a craft in lunar orbit--and could keep a platform in orbit--using the solar sail to help the craft fight the effect of mass concentrations that make lunar orbits tricky.
With a human there--and no atmosphere to speak of--the solar sail would be deployed by hand and any Galileo type dish trouble fixed on the spot. The sail would be able to tack close to the lunar surface perhaps--without an atmosphere to drag it down.
Orbital modules left behind could serve as a useful survey craft that could fly quite close to the moon, and even use some of the reflected moonlight for solar power on the 'bottom' side. If the orbital module is too heavy--it can be cast off.
No controlled landing will be possible--but having a cosmonaut or two in dedicated non-tourist missions would allow the controlled deployment of a solar sail in an environment with very little atmospheric drag--to better calculate the real effects of the 'push' of sunlight upon a sail. Thus the planetary society would not need to launch a dedicated craft to LEO--and merely hitch a ride and help pay for its cost.
I dare say that this effort may even be more profitable than LEO/Suborbital missions in that they take place in a unique environment.
This is cheaper than dedicated EELV lunar robotics missions in that you will have a human presence to help deploy the craft right away--and the cost will be split using cheaper R-7 and/or Proton booster.
HLLVs will be used for landings--and the expensive EELVs left out of the loop entirely.
Here is what I'd like to see. Get a hoax believer and have him deploy the sail. Then slam the hatch shut when the sail is away and do a burn for Earth--and let him get back on his own.--or crash next to the Apollo II LEM stump so that its the last thing he ever sees...
On a serious note--the craft will probably be on a fast flyby--but a solar sail module could still be detached during the mission in some way.
It might be that only the new big Long March can put a Shenzhou in anything like a useful orbit around the moon. Something could be done with the orbital module in some respect.
