Spacecraft flew hundreds of thousands to hundreds of millions of kilometers from the earth, injecting speed when the size and direction of a slight error, arrived at target planets will appear large deviation error, for example, when Mars probe injecting speed 1 m/s speed (about one over ten thousand), arrived at Mars, about 100000 km distance deviation. Therefore, precise control and navigation must be carried out during the long flight. Flying to the moon is usually controlled by the orbital control system of the ground and space probe (see orbit control). Interplanetary flight distances, radio signal transmission time is long, the real-time remote control, can't so planets and interplanetary spacecraft orbit control system shall have the ability of autonomous navigation (see interstellar travel navigation and control). The United States, for example, "pirates" spacecraft in space flight of more than eight hundred million km, for 11 months of 2000 times of autonomous orbit adjustment, the final surface to achieve a soft landing on Mars, placement accuracy up to 50 km. In addition, in order to ensure the accuracy of the orbit control engine, the communication antenna is always aimed at the earth, and other systems work normally, and the detector has the autonomous attitude control ability

What is the priciest car to insure? According to Insure.com's 2010 annual survey of car insurance costs, the most high-priced car to insure could be the Porsche 911 Carrera GT2, a 2-door coupe costing typically about $2900 per year to insure.

The principles of mechanics are employed inside making from the simplest of objects like nails and screws on the huge and complex machines like rockets that cross the solar system and exceed. There never will be a insufficient potential for mechanical engineers though there might be described as a reduction in professions due on the introduction of robots along with other automated machines and a lot of software. This in turn will lead to the boost in jobs for people who maintain those robots as well as their automated machines. Now let's explore the salaries of mechanical engineers at various numbers of their career and which countries and which organizations or fields pay more.
