Once construction is complete theres no reason why a single HLLV cargo launch and a couple crew rotation CEV's can't be launched for well under $2 billion a year. And with much more capability.

There needs to be much research done on many earth creatures to see how they adapt to varying degrees of gravity to learn there potental usefulness in exporting to other places. Especially livestock.

Though I'm not sure if ants are something we want to export.  :;):

Cause we didn't travel 250 million miles only to have our picnic ruined by our own ants.  :;):

Maybe in the distant future when half kilometer asteroids are hollowed out, spun for gravity, decked out with closed loop life support, and used as nomadic space colonies that make orbital "port calls" once every couple of years.

Even then, it would be much quicker to take a shuttle to and from it.

http://www.spacedaily.com/news/mars-fut … tml]Russia Plans Two New Missions to Mars

Moscow (UPI) Jun 20, 2005
Russian space officials said Monday they are preparing two unmanned missions to Mars before 2015.

Georgy Polischuk, director general and designer general of the Lavochkin production and science association, was quoted by the Interfax-AVN news agency as saying the first mission is scheduled for October 2009.

A research craft will orbit Mars, and then a rover will be dropped on the surface of Phobos - one of the tiny twin Martian moons, to collect soil samples to return to Earth.

"The spacecraft will work on Phobos for three years," Polischuk said.

The second mission is intended to land on Mars to conduct various experiments, he added.

"The exact date for (the second) mission has not been set, but it is planned for 2015 at the latest," Polischuk said.

Both missions have been included in Russia's space plan for 2006-2015, he said.

Best of luck to them. I doubt we'll hear about this again for a few years though.

Boy, talk about a bad week for Russian launchers.

It seems to me that if it was broadcasting a signal at all someone would have picked it up by now, no matter what orbit its in.

Nifty.

Speaking of radiation, crews on long distance treks will need more protection than a tin can on wheels can be expected to have.

Carting a backhoe around with you might be useful scientifically and to dig yourself an inprompto bunker in the event of an approaching solar storms, but we may be better off building a more robust chassis and frame to support to permenent placing of sandbagged-regolith "shell", making a sort of turtle car. This will also protect the electronics and astronauts all the time. If solar panels are applied on top of it, it will also provide more surface area for them. Once we are more established we can swap out the sandbags with far denser and more effective per weight bricks.

Any time you can block out a couple more rads, you should do it. It will allow you to budget outside time to more productive activities.

I have a realistic view, your's is based on childish fantasy. 

Why do you argue so for humans to risk so much to go to the asteroids when there is nothing there that we need?  You call that advancement or evolution when it would simply be a waste of lives, money, and resources.  All of that for what, more rocks. 

Why don't humans live in antarctica?  Because it would be stupid.  But still you argue for it. 

It's a good thing you trekkies never get what you want or a lot of people would die needlessly.

You know Dook you would make a excellent King of Portugal.  big_smile

Might makes what is. Whether its right or not is up for the individual to decide.

Power is just a tool.

http://www.spacedaily.com/news/iss-05zzs.html]Griffen pondering more changes to ISS configuration?

Griffin said: "It is our intention to launch the Columbus (science) module and all the international partner modules. We have obligations to the space station partnership and we take that seriously."

Asked as to what the revised launch and construction program would look like, he said, "We are looking at other possibilities, other launch vehicles, delays, various possibilities."

It will be interesting to see what they come up with.

If I were running things, which of course I'm not, I'd discontinue the shuttle, and suspend ISS construction for the time being. Let the Russians have free reign over it for a while, host all the tourists they want.

I'd focus all our funding on the a reusable CEV (launched via EELV), SDV (Its the quickest choice at this point), and Lunar Transit stage (reusable, launched via SDV, stored permanently in the most appropriate parking orbit). These should be operational by 2010-2012.

Now since we still have all these ISS modules floating and sitting around, and partner countries wanting their moneys worth, we take the ISS by the grapes and make it work for us. By 2010-2012, the core modules (Zarya, Zvezda, Unity) will probably be on their last legs without Shuttle support. We build and launch a big single new core module on SDV at the most useful LEO location. And were going to make this one right, as in not designed to be babysat by anything on a regular basis. Then we use a pair Lunar transit stages, one equipped with a HAB and a Shuttle like arm, and one with just the propulsion unit, and disassemble useful pieces, primarily the Destiny Lab, whatever truss pieces, mechanical arms, and solar panels engineers think are still use full, and send them to the new core. The rest still in orbit is disassembled into safe sized pieces and sunk.

This new core will accommodate all the remaining ISS pieces to be launched via SDV, and be the cornerstone of an "ISS 2.0". This station will be designed as a test bed and launch point of VSE based missions. It will be designed from the outset to support numerous new modules, even rows of converted SDV ET's that sure as hell better not be thrown out. This acreage will be used as a growing test bed for the closed loop life support systems needed in transit and on the surface of whatever bodies we land on, and should be able to produce foodstuffs to be freeze dried and used on lunar and other missions. It will also be open to commercial interests.

Without the shuttle and immediate ISS duties gone, there’s no reason a reusable CEV, and SD HLLV can't be completely operational by 2012.

The lunar transit stage should also be ready by then, although the name is a bit deceiving. Its really intended to be a all purpose craft for a full range of missions, from long term LEO missions, to space construction platform, to propulsion for a lunar cycler and cargo delivery, manned lunar expeditions, even trips to Near Earth Asteroids and Venus Orbit. At its core is the propulsion unit, including an extremely reliable chemical rocket, and a series of power systems, and a couple solar arrays. In the front there will be support structures for HAB, ports for a CEV, Fuel, and a Lunar Access Module, and mechanical arms similar to those on the shuttle or ISS. The HAB version will be the basis for a Mars transit ship. It will require a series of them put together.

A series of these will be built and launched once the SDV is online. Their first tasks include the ISS 2.0. Once that’s done they can switch roles, ditching unneeded equipment and weight, at the ISS for later pickup.

None of that requires any new technologies, just applying it in the right way.

I would perfer a revolver like craft with the pressurized cabins revolving around a center axle.

Tethers make me nervous.

A Rocky planet?

So its covered in boxing rings?  big_smile

Aren't we all dreamers, who no longer work on government-contracted space weapons development (yes, yours truly also, back in the Fatalist-Fifties) in these forums?

Well technically, I'm a dreamer who never worked in government-contracted space weapons development. big_smile

#745 Re: Human missions » Shuttle derived revival - Space.com » 2005-06-07 17:07:28

If NASA is seriously committing to a renewed Heavy Lift launch capability, then it means we're ultimately going to see manned missions beyond Earth orbit. 

No currently planned Earth orbital missions require heavy lift.

Going to the moon does not require HLLV or SDV. It can be done without HLLV or SDV.

Putting any decent sized structures on it, or at least the machinery to build them will be very difficult without a HLLV.

It should be noted that HLLV is not for manned flight alone. One reason the Prometheus program, specifically JIMO, was put on the back burner was the lack of launch capability.

Lastly, trains have been replaced by aircraft due to their higher speed and absence of rails. Rails cost money to maintain and consume land that can be used for other things. The elevator cable would be the equivalent of rails. Would a SCRAM jet SSTO make a space elevator obsolete like airplanes made rail roads obsolete?

We still have trains to haul heavy cargo, and that will be the elevators primary purpose.

Population growth is slowing down in the developed countries. The developed countries will eventualy follow suit.

The question is what will happen when medical technology catches up, and education does not.

#748 Re: Not So Free Chat » Watergate:  DT revealed » 2005-06-02 21:31:10

The funny thing is according to the ring leader of the break in, they were investigating a prositution ring.

If that is true, Nixon would have been considered a boy scout if he owned up to it.

#749 Re: Unmanned probes » Juno - Jupiter Polar Orbiter » 2005-06-02 21:21:41

I would have thought the luner sample return mission would have been a no brainer.

Not that Juno is a bad idea, but if their going to spend $700 million on a mission to Jupiter, I'd rather they roll that money into the Prometheus class missions like the JIMO. They can probably pack any sensors they put on Juno on it as well.

#750 Re: Life support systems » life support proposal - water/waste recycling, food production. » 2005-06-02 21:15:20

Interesting.

Have  you considered hydroponics?

It would eliminate a lot of soil processing, and have higher output. The downside is it would require a bit more power and maintainance to run the pumps.
