#1 Re: Interplanetary transportation » Cost of the Ares-Z » 2008-02-29 10:57:29

the Ares V won't launch anything useful in 1 launch neither. it is still a 2 launch option. which imo, it's a wrong move.

since it is still gonna be a 2 launch, why not just go with 2 shuttle-C launch? the Ares is unproven, the SRB had to be redeveloped which really you might as well design a new rocket if you are still gonna pay to development cost with this option too. and now, they can't even figure out if the Ares I can work or if it even can carry enough load.

it is just crap.

[rant]
the reason NASA when with Ares and CEV is because of the NIH (Not Invented Here). the contractors offer better solution to achieve the goal of reaching the moon. but NASA just refuse they, and the stupid part is NASA actually pay them for that, i mean if you not going to listen, why ask?

then NASA has to pull from their arse the 6 crew requirement.... why 6? because 6 is needed for a mars mission... when is the mars mission? when the CEV is retired.... WTF!?  lol  roll  yikes  :? seriously, it look like the space shuttle all over again... [/rant]

#2 Re: Human missions » Minimal Gravity » 2008-02-29 10:43:07

Common sense would suggest to me that mildly higher gravities (say, 1.1g or 1.2g) would correspond to constant workout, making us very athletic, low-fat and less prone to cardiovascular diseases since every time we moved it'd be like carrying some dumbells.

Unlikely. Gravity has been constant on Earth since it was formed and certainly since life began. Why should an organism evolve to take advantage of something that never changes?

even heard of a term: "side effect". just because we weren't build to take advantage of it, doesn't mean we won't. we will only get answers from science and experimentation.

#3 Re: Human missions » Orbital Craft Cost » 2008-02-28 12:29:28

one have to consider if the craft is usable. i suggest you look for details regarding the Kliper.
http://en.wikipedia.org/wiki/Kliper

it seem to roughly fit the scale, hopefully the contractors got a unit price for it and you can estimate from there.
the development is expected to cost USD$600 million. (maybe more if USD continue to fall)

#4 Re: Human missions » China's future Wenchang Space Center and HLV. » 2008-02-28 12:21:42

China doesn't have a coastal space center like JAXA, NASA and ESA. and a landlock space center would limit the size of the rocket to the size of the rail or cargo planes.

i believe, the Hainan site is neccessary before china can deploy a heavylifter. so i think the speed of which it is being completed would be a good indicator to when china will have a HLV capability.

the only landlock HLV are the energia which required it's factory to be at the space center, and the proton which uses an unconventional design, of surrounding a center tank with 6 other tank, so each tank would still be within the size which can be rail transported. but the CZ5 is an conventional single tank design; so they either have to build onsite or choose a coastal site.

The difference between America and China is China is not democratic and doesn't give Tibeteans voting rights whereas America does to Native Americans.

voting right is quite useless when all your options are bad.  lol there is no way George Bush Jr is doing a better job that the leaders of china. and hillary? mccain?... obama? :?

i am a chinese, i know what china need. it is call a constitution. democracy is meaningless if it doesn't protect the people. what china needs to improve is it's laws. that is what is really protecting the people. if china became a democracy, and the leader are allow to play racial card to win majority vote, you think tibetan will be better off?  roll

democracy is misunderstood as "the cure", but that is not what is really protecting people. democracy didn't save iraq, people are still fighting because they think the government is bias to the majority, and such is the reality. i don't want to see china fall apart like USSR or Iraq. i rather take the right kind of reform. that is to improve the constitution, to improve the law of governance.

it is difficult to change to individualism, china has existed like this of 5000 years. the books, the writing... the ideas... isn't just some communism crap, this is tradition: family before self, and nation before clan. it is what allow china to endure and not lose it's culture despite defeat. china of today will still accept changes and new ideas, as younger generation come to see the benefit of the system and liking it. but it not something anyone here will push for anytime soon, we have enough revolution and chaos.

peace and growth is good, disturbing it just to make a point (aka Iraq) is a bad idea.

btw, if half the taiwan people doesn't want seperatism... can china have half the island back?  :oops: sorry i am being evil, support democracy when it benefit... big_smile  ok, this is just a bad joke.

Do please, I joined this forum to discuss space not politics. I came here to discuss Skylab, Voyager, Shenzhou, Venera and not to discuss Donald Rumsfeld or Mao Zedong

off which can we just start a new thread? this is like 4 years ago when we are still debating if china can even get to space...  roll
