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
I guess I am fortunate, in that I have two sets of children, my two oldest sons, 32 years and almost 31 years old, and after that I have the twins, Jon and Ashley, that individuals adopted as babies, that are now 19 years! It was hard to watch my older sons get their driver's licenses and lower the road alone the first time, but I only shed a few tears. My boys were now teenage boys and I was surprised how short a time it had been since they enjoyed little Tonka trucks and Matchbox cars.
For years, car and motorcycle enthusiasts have been replacing their standard steel wheels with larger alloy wheels and hubcaps.

Not only do they supply a smoother ride than regular steel wheels, but in addition they are flashier and allow vehicles to face out. This trend will not be lost on manufacturers; even new SUVs, compact cars and vans are coming equipped with large and flashy alloy wheels.
