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
Americans value teamwork, and tolerance is one of their most cherished cooperative foundations, because they know it's a real team strategy to retreat. Hugo once said, "the broadest sea is the sea, the sky is wider than the sea, and the sky is more broad than the sky." This is true whenever and wherever, even in a competitive job market, tolerance is a shortcut that allows you to fit in as quickly as possible. Tolerance is the best lubricant in teamwork, it can eliminate conflicts and wars, enable team members to weight each other, each other, harmony, and focus on their work, experience the joy of cooperation. Just think, if you're furious at someone, even if it's your fault, no one can guarantee that he won't retaliate against you in the same manner. In this way, the contradiction is inevitable.

Generally speaking, the invention of technology is the materialization of scientific knowledge and experiential knowledge, so that the theory and knowledge which can be applied can be realized. The development of modern technology and the guidance of scientific theory have become the "application of science" to a great extent. However, the development of modern science is also inseparable from technology, which often becomes the aim of scientific research, and the development of technology provides the necessary technical means for scientific research. There is a relationship between them, mutual promotion and mutual restraint. Predictably, their connections will become more intimate and boundaries will blur
