I suspect a radar system of reasonable power to detect incoming rocks far enough out to make evasive manuevers will be standard equipment on any transit vessel.
Besides, we are just as interested in the ones that don't hit us as the ones that could.
I'm surprized the Russians never sent up a rover whose purpose was to plant a flag and take a picture.
Must we fight? Theres room for both.
EELVs for manned launches, resupply, small probe launches, ect.
SDV HLLV for large lunar and Mars ship components, surface bases, space stations, large nuclear powered probes, ect.
On a side note, what are the odds that if a SDV is used that they'll revive the old liquid fly back booster idea.
With colonization of the moon or mars it means that exploration or science objectives are done. This is a problem since governments are there to do science and not to colonize. Since there is no low cost means to get there and no return profits other than the price per seat to go. Making that last step to start colonization will be difficult against the goverments stacking of the deck IMO.
Science and Exploration will continue all throughout and long after "settlement" is completed. We are still learning alot about the Earth, are we not?
I don't think colonization will be difficult, relatively speaking. The first teams will be be expensive, but once their established, they can build the support systems for the next batch arriving. Once thats complete they are free to explore their interests. The new batch does the same for the next new batch. Sort of like indentured survitude. After a while reuseable transit ships can bring new colonists every launch window, or less.
Whats the point of even unmanned exploration if people are never going to go there?
http://www.spaceref.com/news/viewpr.htm … stronomers urge Congress to continue Hubble Science - Johns Hopkins-led team presents new option
The Hubble Origins Probe
Intended to replicate and to improve upon the design of the Hubble Space Telescope, the Hubble Origins Probe offers an option that is low on risk yet high on scientific returns, according to Norman, principal investigator for the team that also includes Johns Hopkins astronomers Holland Ford, Warren Moos and Tim Heckman.
For instance, HOP would make use of instruments - the Cosmic Origins Spectograph (COS) and the Wide Field Camera 3 (WFC3) - originally built to be installed on Hubble during its fourth service mission. In addition, it would include a new Very Wide-Field Imager that would "greatly enhance the original science mission of Hubble," Norman testified.
That Very Wide-Field Imager, slated to be built in collaboration with Japanese partners who will underwrite the cost, will allow scientists to map the heavens more than 20 times faster than even a refurbished Hubble Space Telescope could, Norman said. What's more, the new Japanese camera will be open for use by the worldwide astronomical community based on a peer review system in the same way that all Hubble instruments have been.
Norman told the committee that it would take an estimated 65 months and $1 billion to launch HOP, which he stated would continue and even expand upon the flow of science and discovery that has made the original Hubble Space Telescope a "national treasure."

I doubt they'll kill it. They'll never use a reactor on the VSE without testing it first, and they'll never spend that much money without a serious science mission attached.
Prometheus is nowheres near ready to get off the ground.
And no, we do not need a new space station to get to the Moon. The development, construction, and launch of a space station as a Lunar way-station, would bankrupt the Lunar program.
What we should do is put together a nuclear powered reusable transit stage to take heavy surface modules to the Moon. Otherwise we'll do 3 times as many single shot launches to get to the surface.
In order to build it we're going to need a small construction station. Nothing fancy. Maybe just a single bigelow inflatable with a some scafolding and a couple Canada Arms to build and refuel them.
You would have to devote a lot of resources to the project if you wanted the astronauts to be able to grow all of their own food. That is why they are starting with small scale expiraments.
The biggest investment would be the volume. Water can largely be recycled. Minerals for a hydroponic system would probably not be needed in a quanity that would be terribly difficult to provide. Lighting units are power hungery, but we probably won't go far without a reactor.
Gravity, or the lack there of, might be an issue.
Not having any plans to use the ISS is a good thing, because the ISS is useless, wholey and utterly. There is not enough science that can be performed there to justify its cost, the ISS has always been a make-work program for US and Russian space agencies.
If other governments want to piddle around with it, fine, but we're going to the Moon.
Its all apart of our master plan to handicap the rest of the world with a 1980's designed rickety old station while we do bigger and better things.
That said, I still think that theres a need for an orbital platform. One capable of varitable gravity, growing food (and actually eating it) of both the crop and livestock varieties, testing space reactors and active radiation defenses.
Basically simulating a full Mars transit.
Ah, shouldn't we be growing food to.. you know... eat it?
As for the Europa idea, could this work? For some reason this almost seems like it would be easier to add mass to, considering how many other Moons could be used for raw materials.
Would adding mass to Europa put it in danger of being pulled into Jupiter?
Probably not very far.
Though I'm not sure how effective terraforming Europa would be. I would imagine it to be far more effective to just melt holes in the ice and live submerged in the ocean, either on the ocean floor or suspended at some depth.
Theres no better protection from Jupiters magnetosphere than all that water.
The only worthwhile way to save it is to deorbit it to the ISS orbit and let the Shuttle do it there while there doing there ISS construction duties, or leave the parts there and let the ISS crew do it.
The trouble is it is not in the best orbit for that, and would require a very strong OMS module to do it. But this can likely be done for less than any other method currently on the table.
On Mars they've determined methane comes from either volcanic activity or life.
Could the same be true on Titan?
Still, I'm wondering how any tension-based system will adapt to some of the difficult surfaces a human body has. The concave underarms could be problematic and trying to comfortably apply this to the male genitalia could be a design nightmare.
???
So much for live EVA coverage. :;):
Here is a thought, cross a run of the mill tread mill, a flywheel for energy storage and give it 4 wheels that each are steering capable. Now the astronaut can just walk his way there.
How bout a heavy duty Segway? Thats probably been mentioned already.
Commodore,
The reason it costs alot in America, and Europe Space Programs is the cost of labor in Western Terms. China could purchase the construction , manufacturing and other non- critical labor at a lower cost then we have, at present, over the next few years the wages costs will rise , but that is after the development of ground facilities, living areas for staff, training facilities to expand the crew facilities and more. The Chinese Universities could be used to develop the telerobotic systems and help deploy these assets before the Americans and European keeping the development costs for the space station and other space based assets down .
I wouldn't put it past, the chinese to commence the development of a chinese owned and managed space station in 2008 to usher in a new vision for china and the global extension of the chinese national identity.
Yeah but the only thing that keeps those costs down is the will of the Politburo. That works great for those involved in the program, their wish to go to space is just as strong as ours, but theres countless other areas in the Chinese economy were this won't stay intact forever.
I don't know why everyone assumes that we can't survive a climate change.
Massive hydroponic farms can produce all the food we need year round regardless of whats going on outside. Were not going to run out of water, even if it means we have to put up desaltation plants. We can even build massive dikes to protect population centers.
The climate changes on its own anyway. Wouldn't we look silly when a couple hundred years after we abandon fossil fuels the temperture stablizes, and then starts rising again?
Massive hydroponic farms need a lot of building so by the time we have them built most people will have starved. Then it beggars the question how would you power these Farms if we have a winter that lasts a few years how would you heat them or worse we have the wild weather that destroys everything except the super toughened flood proof buildings, which also have to be well away from the new ocean shoreline
All of these things require fuel and energy to operate. If there is no fuel or energy then you starve. And even if you manage to get a powerplant working how do you get the fuel for it?
No its a lot more easier to actually just make sure we dont have the problem in the first place. Because whatever happens if we such a disaster then our society will change and possibly be destroyed. Nation states would certainly be destroyed and it will become small communities looking after themselves
Oh I agree it is simpler to end use of fossil fuels. We will be seriously screwed if when the day finally comes that the tap goes dry and were still thristy.
But, there is still a strong chance someday we will have deal with climate change anyway. Even with future technology, I can't see it being any less dramatic than it is now, especially since the population is only going to grow.
We might be better off addressing some of those issues now.
Ground scopes have lines a mile long as well. There arn't enough of them to go around.
Theres no reason why it can't, although I think by the time the investment is put into it the requirement will have evaporated.
Phobos is destined to be a space station/elevator anchor.
China is going to have a big problem paying for much of anything when the their capitalist economic sector "self corrects", much less a space program. Compound that with when the Commies finally get the boot and the army loses funding.
Eventually their economy is going to ramp up to a point that only India can compete with. In the short term they are useful competition, but they have a long way to before they can expect the long term sable growth needed to support a space program.

The problem with allowing corporal punishment is that it WILL be carried to extremes and children will be maimed and killed.
No, it won't.
Someday, some where, somehow, it will.
The question is are we going to punish all parents to 18 years of hell and society to dealing with a bunch of spoiled brats ont he account of a couple of bad apples?
har... har... har...
I'm for a united, democratic human goverment spanning were ever humans go. Wheres my party?
So clearly the problem is Earth. For some reason those fighting for the Islamo-Fascists were allowed to leave Earth. I don't believe being a merc doesn't give you geneva convention POW rights. They are instead spys.
That said, thats no excuse to make life of the average Martian miserable. They are mercs, not zealots, and are probably looking for a new, peaceful life on Mars.
So sign me up for the opposition party in the US.
