| A new kind of radar has been developed
for spaceship travelers. A working laboratory model of a new system of radar
that makes use of a beam of light is said to be ten thousand times more accurate
than the best comparable system of radar that used microwaves. The model has shown that this radar system, known as laser-doppler radar, can measure with absolute precision speeds varying from spaceship orbital injection (进入) velocities (速度) of five miles per second down to virtual stops—speeds of less than one ten thousandth of an inch per second. According to the scientists who are developing this system, such fine measures of velocity are of prime importance in space missions. In a rendezvous (对接) between two spaceships, or in a landing approach by a vehicle onto an orbiting space station, a bump could rip open a ship’s skin, or a A. accuracy in speed measurement is essential to spaceships B. the speeds of space vehicles will vary C. inaccuracies in measurement could cause accidents in space missions D. a bump could affect the preciseness of the laser-doppler radar [单选题]依据《中国南方电网有限责任公司网络安全管理办法》（Q/CSG218007-2018），信息系统规划与建设安全管理
