denoir 0 Posted January 10, 2004 Wasn't there an Ariane that blew up spectacularly? Yeah, a few of them actually  And it's always the damn software. It's not out of masochism that NASA and the Russians are running antiquated software. It's very old, but reliable. I know a guy who worked as an engineer on ESA's recovery crew. After one of the Arianes exploded they dug up the main computer in the middle of a jungle in South America in a 5 m deep impact hole. It was intact  Well, they seem to have gotten the bugs out for now as the Ariane is actually the most used booster today (mostly for putting satellites in earth orbit). Edit: Here's a nice video of the ballistic Ariane, decorating the swamps and jungles of French Guayana Share this post Link to post Share on other sites

denoir 0 Posted January 10, 2004 Ouch, I wouldn't want to have been a Russian rocket scientist . Yeah, liquid fuel's the cause. NASA uses solid fuel boosters. Both systems have their advantages - solid fuel boosters are much safer. The Russian rockets have to be filled up before launch and that's where they've had a couple of accidents, especially early on in their space program. Quote[/b] ]Definitely much more reliable than the shuttle, considering we've lost two shuttles. Not quite comparable as the shuttles were reused many times. It's two lost out of over a hundred shuttle missions. That's not so bad. Share this post Link to post Share on other sites
toadlife 3 Posted January 10, 2004 Quote[/b] ]I can't believe why anybody would use anything else for physics as it is really the standard for physicists and engineers everywhere, including the US.Hopefully they learned from that mistake I hope the scientists have, the regular American people still want to stick with the American (aka screwed up) system. Actually, I think the government here once tried to change road signs to metric. Of course, some people who were too lazy to learn metric (How hard can it be ) decided it would be a good idea to shoot the signs and knock them over. Your everyday slice of Americana . I know the metric system, and I'm american. We are taught it in school you know. It would be rather annoying for people like me who have grown up with inches/feet/miles/gallons/pounds/ ect, but it would only take one generation to get acclimated to it.

bn880 5 Posted January 10, 2004 Well, to yapp some more on the metric/imperial stuff, construction is still often done on the imperial system in Canada. I have had several courses throw in imperial measurements as recently as a few months ago. You can bet I'm sitting there pretty pissed off. Share this post Link to post Share on other sites

Plus, once you start using it you will have a much easier to learn system. As opposed to the imperial system, the metric system is interally consistent. 100 cm = 1 m 1000 m = 1 km and the same for the rest 1000 g = 1 kg ... While you have 1 feet = 12 inches 1 yard = 3 feet 1 mile = 1760 yards .. and a completely different system for weight etc.. So apart from people being accustomed to the old units, there is really no reason why not to switch to the metric sytem. Your life will be easier and you'll crash fewer satellites into Mars Share this post Link to post Share on other sites

denoir 0 Posted January 10, 2004 I don't know why, but I really don't see anything superior in the metric system, except measuring ammo is less confusing. It's much more simple. Everything is a factor of 10 and the system is the same regardless if you measure distance, mass or any other physical quantity. In physics it's absolutely essential or the various physical constants get completely messed up. Share this post Link to post Share on other sites
denoir 0 Posted January 10, 2004 Details Emerge for Bush's space agenda Quote[/b] ]Although still officially shrouded in secrecy, the essential elements of the plan have been widely reported by news media including SPACE.com during recent weeks. The salient points include: [*]Construction of the International Space Station will be finished using the space shuttle, after which the fleet will be retired about 2010. Science operations aboard the station will concentrate on keeping human's healthy in space. Â [*]The Orbital Space Plane project will become the Crew Exploration Vehicle and focus on designing a new human-rated spacecraft that will ferry astronauts to and from Earth and serve as the baseline for hardware that will take crews back to the Moon early in the next decade. Â [*]With the shuttle fleet retired, the new initiative will rely on boosters such as the Delta 4 and Atlas 5, as well as international vehicles such as the Soyuz and Ariane. There are no immediate plans to develop a new heavy-lifting rocket in the Saturn 5 class. Â [*]The space nuclear power effort known as Project Prometheus will be folded into this effort, which will focus on enabling new spaceflight technology that can be tested between Earth and the Moon before committing crews to longer trips to Mars. Â [*]To pay for all of this NASA's budget will be increased by some $800 million in fiscal year 2005 and then bumped up about 5 percent each year after that. I'm very sceptical about this part: Quote[/b] ]With the shuttle fleet retired, the new initiative will rely on boosters such as the Delta 4 and Atlas 5, as well as international vehicles such as the Soyuz and Ariane. There are no immediate plans to develop a new heavy-lifting rocket in the Saturn 5 class. Saturn 5 was a monster rocket that could carry payloads of 110,000 kg into Low Earth Orbit (LEO). The heavy-lift version of the Ariane 5 can handle 12,000 kg. The only thing that can carry more than the Saturn 5 is the Russian Energia booster that could handle 200,000 kg. But AFIK that program isn't active any more and the last Energia flew years ago. The biggest thing the US hs today is the new Atlas 5 booster that can take 20,000 kg into LEO. That's less than a fifth of what the Saturn-5's could. Share this post Link to post Share on other sites

I´m not sure if I like the idea of a nuclear fission reactor beeing alpha and beta - tested over my head. Radiation is not filtered that good by atmosphere when it comes to accidents up there.

Acecombat 0 Posted January 10, 2004 Btw from where is Ariane launched? I have seen videos of it being launched from some very tropical country i think it was French Guyana or someplace ... adn only the french were running the operation mainly (i wonder why is that) isnt this a joint european project? Plus i was watching the doco and saw French Foreign legion troops guarding the perimeter they showed a bit of their hectic training too in the jungle , everyone seemed to be french except that they must have had some locals in the ranks too since they all werent white some were tanned local loking folks too (does french foreign legion hire anyone? ).

Arianne is launched from Kourou , French Guyana our installations are there since well before the ESA efforts , we're just using what's already there and adding needed infrastructure when it has to be done, it's a good launching pad not far from equator (i doubt any other european country has pre-existing installations of that kind oversea) Kourou is our business since it's on a french territory on the topic of locals , the legion rarely hires locals for the job since with the years, a certain experience has been gained and accumulated in the guyanese jungle the foreign legion is part ... foreign , might explain what you've seen, "not all white" .... we have south americans, hispanics, south east asians, africans and so on... were these people uniformed ? did they have the legion's attributes ? if yes , then they're legionnaires Share this post Link to post Share on other sites
Acecombat 0 Posted January 10, 2004 Well i dont know their specific uniforms but they were training in the jungle with other french troops so i can guess they were Legionaaires My only question was if this was a joint European project shouldnt there be europeans there too except French only , the people they showed spoke french only so i was thinking maybe this is a french operation only.

ran 0 Posted January 10, 2004 Centre Spatial guyanais European agencies don't have to step on our territory except for ground contral and technical works on the launchpad, it's an european operation but i doubt any european country would like to maintain security forces in such a distant and inhospitable place as Guyanese jungle we have pre-set installations and people already on spot , i don't see why other european countries should have to come in en masse (by the way , there's an old punk song of the 80's called Cayenne by the band Parabellum about the Cayenne penal colony and what has led a man to this prison , nice song , really) Share this post Link to post Share on other sites

The Ariane rocket is a ESA (European Space Agency) project. Kourou is french territory tough so it's protected by the french. But the scientists/engeneers/groud contol people there are from different european nations. In short: The space programme is joint european but the launch pad is french ;) Share this post Link to post Share on other sites
