wolfy 12 Posted August 14, 2012 Share Posted August 14, 2012 The fuel and rocket mass plus inertia is how it works in space. If someting hits space it carries on moving at the same speed it hit the space threshold at. Infact it speeds up over time....Einstein had trouble with this so I forgive Wolfy. If you think about it. A rocket cannot push against itself. I know scientists tell us that but it's wrong. On Earth, a rocket burns it's fuel and the thrust and the heat expands the gases around it (the atmosphere) which propels it upwards. In space , the vacuum nullifies this as it simply gets swallowed up as fast as it comes out creating nothing. Link to comment Share on other sites More sharing options...
Park Life 71 Posted August 14, 2012 Share Posted August 14, 2012 It pushes against the rocket's body itself, and the easiest path is straight out of the bottom of the rocket. As you're in a vacuum, there's nothing to push back the other way, and you accelerate freely. Yup and over time faster due to lack of resistence. Nasa are shit anyway starved as they are of budget (which goes to the military programme). Link to comment Share on other sites More sharing options...
Christmas Tree 4496 Posted August 14, 2012 Author Share Posted August 14, 2012 Shuttles were costing 500m$ per launch. Booster, tiles and other bits needed replacing every time (took 6 months at least). Shit design cause the airforce designed the heavy wings the clowns + Govt contracts are always 100x more expensive...etc.. Yeah, but they were up there anyway several times a year. Cost buttons to pop over once they were already in space. Link to comment Share on other sites More sharing options...

The so called weight of it in a glide would have rendered it a flying brick. Link to comment Share on other sites More sharing options...

If this is true then it's not being pulled to Earth and if something extremely heavy landed on it at great speed then it would surely be knocked out of it's 'orbit' or whatever Link to comment Share on other sites More sharing options...

As you're in a vacuum, there's nothing to push back the other way, and you accelerate freely. How can rocket fuel push against the rockets body and make it move? How can something push against itself, it's like saying you can push your own car by sitting in the back seat and pushing the drivers seat and your car moves along.

Park Life 71 Posted August 14, 2012 Share Posted August 14, 2012 Yeah, but they were up there anyway several times a year. Cost buttons to pop over once they were already in space. The ISS was almost the ceiling of it's real capability (no shuttle has been above 615miles. Although they were designed for 900 odd miles. Up there is a lot of space radiation and there are only a few windows per orbit to get the fucker down...In that sense there isn't much 'popping about'. The main problem with the shuttle is that it was designed for heavy lifting many loads but the design was too heavy hence very fast re-entry and the need for those black tiles which cost a bomb (special ceramic). The whole thing was a colosal waste of money. Russia was lifting loads at about 20% of the cost. Link to comment Share on other sites More sharing options...

If you could sit in space, you can flap your arms about and do what you want but you are flapping against nothing, so you go nowhere at all unless something bumped into you and sent you on your way.

In space , the vacuum nullifies this as it simply gets swallowed up as fast as it comes out creating nothing. Juvenile misunderstanding of how a rocket works, either in the atmosphere or space. Newton figured out his second law of motion over 300 years ago. You could look this up but it does involve an equation and a bit of common sense so I'm afraid it would be lost on you. For you it's like the Enlightenment never happened. You may as well go the whole hog and believe in a flat Earth. Link to comment Share on other sites More sharing options...

It still apparently glided to Earth though, every time didn't it. Look at the design of it. There's no way in hell something like that could glide.

If it was so easy 42 years ago it would be a piece of piss now. The distance was nothing then so would be even more of a nothing now. Link to comment Share on other sites More sharing options...
