Bookmark or Share- launch - What G-forces do different launchers cause? - Space ...Some scientific payloads are extremely sensitive, I wonder if they prefer a certain rocket over others, and if the payload is designed with a certain launch system in mind from the beginning. From watching videos, I get the impression that an Ariane 5 races much faster from the launch pad than does a Falcon 9.
- What is the vapour/smoke that comes from a rocket before launch?While a rocket is waiting on the platform during the final countdown, it often seems to have clouds of steam or something similar escaping from it. Is this normal, and what are these clouds?
- How close can I get to a rocket launch and not get killed?It would vary for each type of rocket. The more powerful a rocket the greater the safe stand-off distance. A rocket like the Saturn V would require a larger stand-off distance than a Proton rocket. It would also depend on what exhaust directing structures exist below the rocket at launch and where the person wanted to be in relation to that.
- rockets - Launch Accelerations: Values, history - Space Exploration ...Other things being equal, a higher-g launch can be more fuel efficient, because less energy is lost to gravity by getting to orbit more quickly, and gravity losses normally dominate over drag losses. Keeping STS down to 3g was a challenging design goal - it's hard to build deep throttling capability into an engine, but the shuttle was designed ...
- launch - What is the success/failure ratio of space bound rockets ...There are thousands of satellites orbitting our planet and everyone of them got there from a rocket launch. I know that when a launch fails it is practically always a catastrophic failure, otherwise its a minor or major setback and the launch is rescheduled. What is the failure rate of space bound rocket launches, in general?
