At the time, the country was 11 years from sending its first astronaut into space, and its space efforts were going through a rough patch: Chinese rockets failed in 1991, 1992, 1995 and twice in 1996. The worst failure, in 1996, was a rocket that tipped to the side, flew in the wro...
一、 完形填空From the first use of the rocket (火箭) to carry satellites into space to the setting up of space stations (空间站), humans have been putting great effort into space research. And so far, wel many successes. But there are still large numbers of tasks in front of us and...
Since people first launched rockets into space in the 1950s, we have been leaving behind all sorts of things. Some of them, like the camera, were lost by astronauts while they did work outside their spacecraft. But much of the space junk is made up of little pieces of things that were...
space that would get very close to some of the larger pieces of space junk. The satellite would connect a small rocket to the useless object. When the rocket explodes, it pushes the junk into a lower and slower orbit, nearer the earth. After a time, the junk burns up in the ...
Elon’s pumped. And when you learn about the big fucking rocket he’s building, you’ll understand why. First, let’s absorb the challenge at hand. It’s often said that space is hard. To this day, only a few hundred people have been in space, only a few countries have the ability...
After a time, the junk burns up in the atmosphere. Mr.Castronuovo has proposed using a number of small satellites with robotic arms. One arm would catch the space junk, and another arm would connect the rocket. He imagines that each satellite could jump from one large piece of junk to ...

On November 20, 1998, assembly began on the largest, most complex construction project in space. At the Baikonur Cosmodrome in Kazakhstan, the Russian Space Agency launched the first piece of the International Space Station atop a Proton rocket. ...
