It could be - it says that it needed to be carried in the payload bay of the Buran shuttle though?

the handiest converter i use is [http://www.google.com]GOOGLE
Just type what you want to know, straight into the search box, and it converts it for you.
try [http://www.google.co.uk/search?hl=en&ie … in+F&meta=]3C in F - For 3 degrees centigrade in Fahrenheit
or [http://www.google.co.uk/search?hl=en&ie … nnes&meta=]15lb in tonnes
or [http://www.google.co.uk/search?hl=en&ie … +KeV&meta=]19.7J in KeV
or [http://www.google.co.uk/search?hl=en&ie … +BTU&meta=]45Kg in BTU
or [http://www.google.co.uk/search?hl=en&ie … tres&meta=]15 cups in litres?!?!?!?!?!?!
Its actually quite fun! What will those people at google think of next?!?! :laugh:
EDIT
That BTU in Kg one really confuses me! ???

Theyre planning on usuing an unmanned soyuz-2 (upgrade) from Kourou - apparently theyd need to convert to much of the existing soyuz to adapt it for emergency ditching into the atlantic.
The new 6 man craft will use a new launcher in the 12-14 ton range, as far as i know.

Im claiming ownership of all interplanetary space in the solar system.
From now on all probes and missions will need to pay my tolls to pass through my space. In fact the planets as they move through the solar system will also be charged, and the moon too!
MUAHAHAHAHA

Cobra:
To believe that large numbers of humans can live anywhere longterm without fighting is to ignore basic human nature and all of our history. It is unsubstantiated fantasy.
Europeans spent over a thousand years killing each other in ever more complex ways, infact we were still at it until 50 years ago. Yet to consider war within europe today is frankly impossible. Are we in europe ignoring our basic human nature? Is the peace in Europe unsubstantiated fantasy? Let me put it another way; Does New Jersey have anthing to fear from New York State? ???

As for countering 0-g, my idea is that if the capsule is at least about ten feet in diameter, just spin the whole thing up to about 20 rpm (Or whatever is needed) during the rest phases. This would provide seven hours a day of bone building gravity, and if one g isn't enough for healthy astronauts, then bring it up to 1.5 or even 2, although I think 1.2 would be plenty. You really only need this much exposure to gravity a day, and spining something like that while people are walking around would give you vertigo, so just keep the freedom of 0-g while everyone's awake.
The artificial g has to be 'on' when people are up and moving around in order to load the bones and muscles.
When people rest they lie down, their bones are not loaded and their muscles are not being used, as such the artificial g during their sleep would be ineffective, and as you stated it wouldnt be feasible when they were awake.
Also, i havent read the plan, but did you take into account the fuel necessary to 'spin up' and then 'spin down' the capsule over 180 times en-route to mars?
#113 Re: Interplanetary transportation » Exploding Antimatter Bombs against the back of an orion » 2003-09-17 15:11:40
At the moment, we can't produce much antimatter or store it very well although we theoretically know how to do both. Initially i would imagine that antimatter would be used as an ignition source for fusion or maybe even plasma engines, only once we can properly produce and store large ammounts of the stuff can it be used for propulsion.
For a pure anti-matter powered space craft? If we have something of a reneissance in space travel and fast expansion out into the solar system, you might see governments showing off their new bad-boys in about 100 years.

The Soyuz/Progess tether practice idea won't fly because no areospace company will make any money doing it. Or maybe I am just too cynical?
It would be a scientific experiment, notthing to do with any of the big aerospace companies.
Also i believe one of the recent soyuz or progress crafts conducted some experiments in orbit before returning or burning up, so the idea is not without precedent.

Yes, its the very best we can do with our current knowledge of physics.
#117 Re: Human missions » Orbital Space Plane by 2008 - Faster, Cheaper, Better? » 2003-09-16 20:53:47
ISS is the only and as such most practical platfrom for conducting the experiments that need to be done. We can bitch about it as much as we like, and we'd be right too, but its there, and it'll get the job done, eventually.
Anyway, the real reason im posting, i just read this article. So depresing; if this is true then im just gonna curl up into a ball and give up on NASA all together......
Space shuttles to last into next decade - Boeing
"There is not right now on the drawing board one vehicle that can replace what the shuttle can do,"
Have they learnt NOTHING!
Since the International Space Station was designed to work with the space shuttle and to stay in service until at least 2018, the shuttle should probably stay in service until that date, Mott said.
"So if you go to 2018 that becomes very logical because that (the shuttle and the space station) works together as an integrated system," Mott said
*Curles up into a ball* <sigh>

I was thinkinga bout this the other day. A company could make money by sending a comms satelite to mars capable of high-bandwidth data transfer with earth. That company could make a fortune selling its bandwidth to the various entities that will be sending a dirth of probes (and hopefully eventually manned missions :;): )to mars over the next 2 decades.
Most probable method would be via laser, i believ there is an experiment being conducted at the moment which is testing out this very concept.

Geothermal energy requires time and infrastucture, and whilst it would make a good colony or outpost power source, it will require to much work and effort for a temporary expedition to construct.
#120 Re: Interplanetary transportation » Exploding Antimatter Bombs against the back of an orion » 2003-09-16 13:47:11
An anti-matter driven starship wouldnt use the orion-ship configuration.
The engine would resemble a normal rocket but with a magnetic nozel and tanks, basically the last step in the line after ion, plasma/fission and then fusion(maybe with anti-matter ignition). Itll be the best 'rocketry' could do for us, and will represent the ultimate means by which we can tool round the solar system, but we will need something else (i.e a fuel-less engine) to take us to the stars.
#121 Re: Human missions » Orbital Space Plane by 2008 - Faster, Cheaper, Better? » 2003-09-16 13:39:41
PUBMED refers only to medical experiments. Whilts i agree with you in this specific area the materials science conducted on the ISS cant readily be done by automated satelites and really requires hands on scientists to be there. Im sure there are plenty of scientists working in a range of fields who would say the same.
There are experiments, in a range of fields, that do need to be conducted by scientists. That said, the ISS is not turning out to be the most cost effective way of doing them.

The OSP will have a small cargo carrying capability capable of taking experiments up and down. Also the ATV and HTV will boost the ISSs orbit whilst docked.

Spiderman, youre being extremely short sighted. We all want to go to mars, but its not the only goal out there, even if the astronauts dont travel to mars in zero-g there will be plenty of missions where they will!
As far as microgravity experiments, if you bothered to read what theyre actually doing you'd realise that its important on going research that can only be done in microgravity.
I do agree with you that mutiple mini stations would be better, different experiments are suited to different orbits, they should be permanent though because there is always on going research to be done. As for the ISS, its there, so we should use it. Mothballing it would give completely the wrong signal and would not free up any money for anything.
Theres more than just mars out there, if we concentrate on just mars then once were finished we wont have the ability or momentum to keep going or do anything else, it'd be apollo all over again.
