Only very few people have use for cure against ALS, but luckily there are people who research it and are close to getting at least a useful therapy.
You cannot compare a disease which afflicts people to an entirely voluntary excersise.
T.Neo, I'm not going to respond to you anymore, because frankly I can't be bothered to go over the same argument over and over and over again. I disagree with everything you post, and I have given you facts that back that up. Whatever I post will not change your opinion, so I won't bother.
You still fail to see my point. I respect your facts, but it annoys me that you do not acknowledge the fact that things could have been done better on the ISS in many respects, that were not.
And I am sure we agree on some things. I'd love to have seen a Centrifuge Accomodations Module on the ISS, and not sitting on the ground as an incomplete shell, used as an ornament...
Where did I say it was a magical problem free vehichle? Where has it ever been touted as such? And this statement is made even more annoying by the fact that in that "snipped" quote I clearly agreed that it was not as safe as it was supposed to be, not as cheap as it was supposed to be, nor as easy to operate as it was supposed to be. That still does not take away from the fact that it was able to carry huge payloads to and from LEO, large crews, land on a runway, and be reused. And it is ludicrous to assume that it is either Shuttle or bust. The Shuttle is over 30 years old, of course it can be improved upon, it should have been proved upon, and I would have rather seen NASA go that route with the Shuttle rather than treat it as an outlier in the slope of spacecraft progress, but rather the model that the next generation of space vehicles can build off of.
So I guess the solution is settled then isn't it? I did a search for "South African Space Program" on Wikipedia and was politely informed that "South African Space Program" does not exist. So keep up that good work. You can stay here no Earth and I would then assume that when any new technologies that arise from the ISS and other manned space programs you will keep your integrity intact and decline their benefits, and continue to laugh at me and others who think like me for being "alarmists" because I don't think 2,000,000,000 more years of human history is quite enough for me, thank you.
We can only imagine what a world we would have lived in if the Kings and Queens of old held your immature mindset on exploration. "Why bother financing ships to sail across that big ocean? Human's cannot survive in water, it will cost a lot of money, we may see no gain in such an endeavour, and even if we did it will take years and years for any such gains to be manifest." Thankfully they saw the world threw the lens of progress. They sent ships over that ocean. They sent colonists to live on those far shores. They continued to send explorer to find out what laid west of those mountains, across that large river, what is past this large desert and even larger moutain range, behold another ocean, what could lay beyond that?
So I will end in asking you to please stop playing the role of the resident expert in anything, as I have found your knowledge in varied topics in just these past few days alone to be narrow and lacking, and your defense in this ignorance to be underwhelming and hostile.
And to save myself further grief I will place you on my ignore list so I can continue to have a high opinion of this place and not have it polluted by the actions of a very slim minority.
I don't care if you ignore me, but I will respond to you anyway, for the... pleasure of everyone else... :dry:
The capabilities of the Shuttle are nice, but the failings of the vehicle prevent them from being worthwhile. In addition, some of these capabilities are not intrinsically needed in the modern spaceflight market. While I too would like to see a development on the Shuttle, it simply does not make sense at this time, even if its core concept is sound.
Just
liking the idea of a shuttle isn't good enough to justify it, especially when it does not live up to its expectations or deliver an overall package with an improvement over competing technologies. I like the Shuttle too, but I fear some take this affinity too far.
And you are incorrect on the fact that South Africa does not have a space program. We do, it just isn't a very grand one. We had a satellite, and there are also some interesting developments floating around here, in regards to spaceflight. But nothing major, and this is obviously to be expected from a small developing country.
And yes, I will laugh at you when you shout alarmism about deadly bolide impacts and the Sun making the Earth uninhabitable. While the former is a risk, it is a very small one, and while the latter is a good point, it is
extremely remote and a pretty bad reason for 'escaping' Earth out of a plethora of slightly better but still problematic reasons.
And yes, it is nice that people continuously cite the colonisation and exploration of old, but space exploration and colonisation are not like that. It's different, we know the dangers, we know the problems, we know the difficulty it would entail, even with advanced technology. History has shown us how the 'promise' of human spaceflight can fail, and there is good reason to be skeptical.
But you don't get what I'm saying at all, of course. I'm not against using technologies developed on the ISS, just like I am not against using technologies developed here on the ground. What I'm saying is that projects like the ISS are hugely expensive and we are unsure of their returns. To maximise the efficiency of projects like the ISS, reducing cost and increasing capability is paramount. This is an argument
for spaceflight, not against it. By increasing efficiency cost/return is improved and justification becomes easier. It isn't about killing the space program or splashing the ISS.
Of course the Earth is important. It is the most important location in space.
The only South African in Space was Mark Shuttleworth. History can be ironic.
Maybe, but he flew on Soyuz, and with his own money.
Ok, prove it. Lets see some facts and cost projections to back this up.
Ok, let's assume first, a version of the ISS launched by vehicles cheaper than STS. Let's take the Delta IV Heavy, with a payload of 22 950 kilograms to orbit and an assumed launch cost of $200 million*.
- The modules are presumably designed to take launch loads and be mounted differently.
- A propulsion module is included for rendezvous with the station.
- The modules are manuvered into the range of something similar to the SSRMS, are grappled, and then berthed to the station. Power, propulsion and manipulation would have to be launched first.
Let's assume the cost of each propulsion module is $75 million, and 20 cargo launches overall- enough to roughly encompass the truss and all modules of the USOS. This would be nearly $5.5 billion, assuming these costs.
Assuming 12 flights of a $400 million logistics vehicle on a $200 million launcher, this is a further $7.2 billion.
Throw in ~2 billion development for the logistics vehicle/propulsion stage, and that is a cost of $14.7 billion. Assuming an STS launch cost of $600 million, 27 construction flights and 12 MPLM flights with a cost of $400 million for each of the two MPLMs flown, that is a cost of 16.2 and 8 billion, respectively, or roughly $24 billion combined.
Replace 8 of the unmanned resupply missions with STS/MPLM and gain recovery capability on some missions for a similar cost.
Spend $4 billion on a minishuttle (similar to HL-20) with a unit cost of $1B each. Assuming station lifetime of 20 years, a flight 2 times a year, a $200 million launch vehicle and a refurbishment cost of $50 million, deliver a crew member to the ISS for $400 million a seat and/or deliver/recover cargo.
This does not include other development costs, module construction costs, experiment costs, ROS/Soyuz/Progress costs, and other vehicle and program costs.
For a free-flying, unmanned recoverable miniature laboratory;
- Assumed launch cost $200 million.
- Spacecraft cost $400 million.
- Total spacecraft mass 20 000 kilograms.
- 5000 kilograms return payload.
- At 2 launches per year over 20 years, 200 tons of flown payload returned to Earth at a program cost of $33 billion (including $5 billion development cost, not including payload costs).
* Cost reduction caused by increased launch rate assumed, may be unrealistic.
Please pick apart at your own pleasure.
