Petrol does not have a high enough energy density. If you have enough of it on board to provide the energy needed to reach orbit, the vehicle will be too heavy to lift off.

What are some problems that occur from mining?
You can get hurt. It can be dangerous mining.
Why must efficiency be calculated and understood during the design process?
So you can account for any problems that may occur while building the object.
What is most likely going to occur if an organism was allergic to proteins?
Death would occur
How do you Describe the problems that can occur with the wiring and testing operations?
Testing and wiring should be carried out by a qualified , trained technician / engineer so that the electrical devices and wiring are properly done with safety.
When does generally declaration syntax error occur?
All syntax errors occur at compile time.
Why do computers determine if Space Shuttles will launch or not?
The Shuttles are extremely complex pieces of machinery, with literally thousands of parts and extremely volatile chemicals (solid and liquid) that must function properly together in order for a successful launch to occur. As such, humans cannot monitor and control the many critical systems and react to problems fast enough during the final stages of launch, so the process is automated.At T minus 9 minutes, a hold is placed on the countdown, and the Shuttle launch sequence is turned over to the Ground Launch Sequencer (GLS) software program at Kennedy Space Center. Upon resuming the countdown, the GLS system is responsible for monitoring critical launch systems for any failure (real or not), or parameters that are outside of established limits, interrupting the launch sequence if any parameter isn't met. At T minus 31 seconds, launch control is switched from the GLS system to the Shuttle's onboard main computers, which is then responsible for detecting any problems and stopping the count if necessary.The NASA Launch Director has the authority to override an interrupt. This is done only upon analysis of the error detected after the launch interrupt, if the error is found to be either false (computers aren't infallible either), or the parameter which led to the launch abort is deemed to be small enough to be worth the risk (it has to be pretty small - safety of crew and vehicle are the first concerns). Depending on the severity of the problem, the Launch Director will either continue the countdown, or delay the launch in order to further investigate/fix the problem if it's severe enough (system failure, etc.)It is not unusual for a Shuttle launch to be delayed due to a GLS abort; during my Kennedy Space Center visit to witness Discovery's launch (anyone who works on a Shuttle payload is entitled to view the launch on-center at KSC), which had no problems, I met a woman who had previously been to no less than 10 other launches. The one I met her at was the first she had actually seen go through, as all the others had been delayed either by computer aborts, weather, or the other many factors that are taken into account before a Shuttle can launch.
What was the name of the space shuttle that exploded during take off and when did this tragic event occur?
The Challenger Space Shuttle exploded 73 seconds after launch on January 28, 1986, killing all 7 brave astronauts on board, including Christa McAuliffe, who was chosen from 11,000 applicants to be the first teacher in space.
What does T stand for in a rocket launch?
T means the Time of launch -- when the launch is planned to happen. T minus is the number of seconds before the rocket is to launch. T minus four seconds and counting means it is four seconds in the sequence of event before launch will occur and progressing toward that launch. T minus four seconds and holding means it is four seconds before launch in the sequence of events that precede launch and the progress toward launch has stopped. The hold/delay can be most any length of time, but once counting begins again it will still be four seconds until launch -- that is, they pick up where they left off and continue toward launch.There are both planned holds (to give everyone time to evaluate things) and unplanned holds when something is wrong. After launch it becomes T plus so many seconds. Actions during launch happen so many seconds after launch. For example, on a Space Shuttle launch, the Solid Rocket Boosters will separate from the Shuttle at T plus so many seconds.
Do all space shuttle launches occur in Florida US?
No
Does a sonic boom occur every time the shuttle enters earth?
Yes, the shuttle has a sonic boom whenever it reenters Earth's atmosphere.

Major ozone problems occur where?
Major ozone problems occur in stratosphere. It is where the ozone is located.

How does the space shuttle go into space?
The Space Shuttle were massively complex pieces of machinery, utilizing literally thousands of mechanical parts that had to work flawlessly in order for a launch to occur.The Shuttles used 2 primary means of propulsion and boosting to achieve orbit:1. External combined Liquid Hydrogen (LH2) / Liquid Oxygen (LOX) tank (orange/rust colored external tank the Shuttle was mounted on)2. Solid Rocket Boosters (SRB's)The LOX and LH2 fuel in the external tank was used by the Shuttle's main engines; the SRB's used solid rocket fuel, and were reusable once the fuel was expended. The SRB's were used because there isn't enough thrust from the Shuttle's main engines alone to achieve Earth orbit.During the initial launch phase, at T minus 9 minutes into the countdown, a hold was placed on the countdown, and the Shuttle launch sequence was turned over to the Ground Launch Sequencer (GLS) software program at Kennedy Space Center. Upon resuming the countdown, the GLS system was responsible for monitoring critical launch systems for any failure (real or not), or parameters that are outside of established limits, interrupting the launch sequence if any parameter isn't met. At T minus 31 seconds, launch control is switched from the GLS system to the Shuttle's onboard main computers, which is then responsible for detecting any problems and stopping the count if necessary.A few seconds prior to engine ignition, fuel vapor burn-off igniters under the engine nozzles would spark to burn off any hydrogen or oxygen vapors that might have accumulated under the engine nozzles. This was done to prevent explosive damage to the engine nozzles upon engine start, which would occur if there were any vapors present.A few seconds prior to liftoff, the main engines and SRB's are ignited; when they reach full thrust, explosive charges blow the spacecraft's hold-down clamps free, letting the Shuttle loose for ascension.Once the solid rocket fuel in the SRB's is expended, they are blown clear of the Shuttle, and descend to the ocean using parachutes. They are then picked up by special recovery ships, and brought back to KSC for shipment back to be refurbished and refueled.The main engines continue to burn after the SRB's are released until the Shuttle achieves orbital altitude and speed. At that point, the external tank is blown clear, and it descends into the atmosphere, where it eventually burns up over the ocean.
