The Starlink system, is a main product of an American companycalled Space X. The company plans to send about 42,000 satellites tooffer much faster and less expensive satellite(卫星) internet around theworld.
In order to send information faster, Space X has put built-inlasers(激光) on its newest Starlink satellites. With the higher speed of llight in vacuum(真空) and the shorter path than undersea fiber(纤维), the laser links in orbit(轨道)help send satellite internet faster. And by getting closer to our planet and networking, Starlinksatellites can quickly send a large amount of information to any point on Earth, even across oceans.
However, some astronomers are afraid that bright satellites in Earth's orbit will make themdifficult to"watch"the universe. And some scientists are worried that there will probably be morespace junk when the satellites are out of use or when the satellites hit others. The junk of course willbe harmful to spaceships or space stations. And when some of the falling junk burn up in Earth'satmosphere(大气层), it will cause uncertain changes in Earth's climate(气候).
Although the company promised that the satellites seemed impossible to hit others, the risk isstill there. In 2021, China's space station had to change its orbit to avoid the possible danger whenStarlink satellites came close to it.
So does the Starlink system really have more advantages to humans in the long term? Or willthe risks outweigh its advantages? We still do not know the answers.
