News: Hubble plans and policy
Here is another means to an end (actually several means), including
the salvage of Hubble along with the task of getting ourselves to/from and of surviving places like Venus L2 and even Mars. Lunar/Moon Space Elevator, plus another ISS situated within the CM Lunar Space Elevator Linear Tether Considerations (CM @1^9 kg): 363,300 km, ME-L1 = 58,128 km, L1.1 = 63,941 km (-1738 km = 62,203 km) 405,500 km, ME-L1 = 64,880 km, L1.1 = 71,368 km (-1738 km = 69,630 km) Not that I'm telling anyone what they shouldn't already know, such as about dealing with space radiation is where I've learned from others (including NASA) of what to expect at Earth L2, within the Van Allen zone and of a couple of altitudes below or in between the Van Allen zone and the surface of Earth. What's oddly missing is any concise definition of what Earth L4/L5 have to offer and thereby of what the lunar surface is like. Even clear information of what's to be expected at ES-L1 seems to have become a secret because, of what there is to be found simply doesn't compute for what those Apollo missions endured by any long shot. Of course, if you have something measured and/or calculated of Earth L4/L5, for the solar maximum year and/or for the solar minimum year, that's exactly what we all need to learn about, so that others or at least that I can estimate what to expect at Venus L2, where I believe the space environment of VL2 or VE-L2 is worth knowing, since even a robotic mission such as a TRACE-II would need to be designed for the radiation environment, as it's highly unlikely that the sun is going to represent a purely UV--IR source of energy, such as during those extremely lucky Apollo missions and, even though the VL2 position is roughly 90% shaded by Venus itself, there's still a good deal of solar influx/weather that'll represent a whole lot more Sv dosage than any human expedition can tolerate within the existing ISS shield capabilities, especially if that's having to be based upon a 2 year mission. This radiation tit for tat is where the idea of affordably obtaining tonnes of that nifty clumping moon dirt comes in real handy. Since we can launch a manned mission, if need be in stages and assembled somewhat like ISS. The only stumbling block is the issue of our having to launch sufficient mass that'll surround the likes of yourself with good enough density that'll effectively shield those onboard from the worst the sun has to offer, not to mention whatever the galaxy has to offer. Unfortunately, besides the rather enormous cost per tonne delivered, the side effect of launching that amount of mass is the resulting deposit of artificially created CO2 for the rest of us back here on Earth, where this being from what I've learned that the overall process of creating such mass and of having to launch along with sufficient energy for a interplanetary mission could represent a 100 fold creation of CO2, which is a darn good thing if it were for a planet like Mars that may need to be warmed up and simply didn't care about further CO2 pollution but, for Earth that another confirmed "no no". Since I've found some references to the EL5 environment in need of as much as 1000 g/cm2 and, I've located information upon the Earth L2 environment and of what certain densities of shielding accomplish, as such I've interpreted and/or extrapolated upon what the EL5 radiation environment must be. Again, if there were a concise set of radiation tables and of sources other than just the cold-war NASA moderated verity, then I'd not have had to bother the wizardly likes of http://clavius.org which no matters what can't stray from their pretentious cold-war outcome of those Apollo missions. As another means to an end, for the prospect of accommodating a depot of moon dirt situated in a nearly Zero-G environment seemed too good to pass up. The idea of constructing a lunar based space elevator even seems entirely possible, especially if the likes of those claiming any Earth based (EM-L1) space elevator should be accomplish, as there's no freaking contest in the fact that a lunar based elevator will become a whole lot simpler and, that it could be accomplished within the current level of expertise and by way of existing materials application technology. The idea of having another ISS configured within the massive lunar space elevator CM depot is yet another win win for all sorts of things. I've proposed a number of my village idiot ideas and benefits associated with having a moon-dirt depot situated at ME-L1.1 (LL1.1), and as usual, all I've gotten in return is either their black-hole voids of nothingness or loads of sanctimonious flak instead of other ideas or specific numbers, as God forbid, should some of our crack space wizards actually stipulate upon anything specific that might end their career that was probably phony to begin with. The following page is simply an ongoing build, receiving corrections as well as whatever feedback that can be put to the test (your input is welcome); http://guthvenus.tripod.com/moon-L1-elevator.htm If you don't know what works but otherwise seem to know for a fact what doesn't work, then that's the sort of information we need, as either way this moon space elevator is a doable thing, especially as compared to accomplishing any Earth based space elevator and/or of our going to/from any frozen and irradiated to death planet such as Mars. BTW; I'm all for saving the butts of those Hubble huggers (I'd even pay or it out of my own pocket), though if only I could think of something morally worthy for such a fine instrument and of supposedly such qualified souls to be focused upon, such as a nighttime side of a certain planet that just might be capable of artificially illuminating portions of their otherwise pitch black though sufficiently transparent nighttime clouds. But gee whiz folks, I guess I can't think of a single god damn worthy thing for that otherwise horrifically spendy instrument that'll soon make for another terrific display as it burns itself up upon reentry (I guess it'll be good riddance to a source of such terrific images of places humans will never obtain an ounce nor a gram of worth in a thousand generations).

I doubt that time would be much of an issue, and it would be an interesting experiment. Unfortunately, if it is an experiment, NASA must plan for the possibility that it would fail. So you don't really gain a lot that way. And as others have noted, electrodynamic tethers are not well suited to doing large plane changes. It's not *impossible* to use them for that, but it's not simple or easy. -- MOST launched 1015 EDT 30 June, separated 1046, | Henry Spencer first ground-station pass 1651, all nominal! | |
