Bookmark or Share- launch - Why do space rockets not start from an angle? Why go straight ...Besides the good answers you already got, note that for a rocket to launch diagonally you need the vertical acceleration to be more than 1g. In a Saturn V, initial acceleration was barely beyond 1g. If you put your rocket at a 45 degree angle, now you need 1.41g just to not fall to the ground. There are also huge engineering issues.
- What are the main steps in the lead-up to a rocket launch?Pre-launch checks. Starting up the rocket: switching on its internal power sources, starting the rocket's control systems etc. Starting the engines and checking if they work properly. Launch. You want to do as much of the work as possible while the rocket is still in a hangar and easy to work on, but some steps are unavoidable on the launch pad.
- What is the vapour/smoke that comes from a rocket before launch?This occurs when cryogenic boosters are used (Liquid Oxygen / Liquid Hydrogen) - as these warm up on the launch pad, some of the liquids boil and to release pressure, bleeder valves allow this gas to escape.
- launch - What is the base of a launchpad made of? - Space Exploration ...The majority of the heat of the exhaust plume can be redirected away from the actual launchpad where the rocket is sat, be it by building exhaust plume tunnels or trenches beneath the launchpad, using jets of water that also double as acoustic shock suppressors and flame deflectors, by using concrete flame deflectors, or as is the case with some launches (e.g. Soyuz), the rocket itself is held ...
- 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 ...
