Our country's space experts tell us that China is now working on a new carrier rocket(运载火箭) and a new manned spaceship(载人飞船).
The new carrier rocket is called Long March-10. A rocket expert named Rong Yi said it is mainly made to make it possible for astronauts to land on the Moon by 2030. It is about 92 metres long. When it takes off, it weighs about 2,187 tonnes(吨). It has a power of about 2,678 tonnes when taking off. And it can carry at least 27 tonnes when going from the Earth to the Moon.
Rong said in a recent talk that Long March-10 is going to have its first flight in 2027. Also, this new rocket can send astronauts and many things to the space station.
The new manned spaceship is also very useful for China to land astronauts on the Moon by 2030. It can be used for flights near the Earth and also for deep space flights.
An expert said this spaceship can carry three astronauts. It is mainly used to send astronauts to orbit(环绕……运动) the Moon and then come back to the Earth.
Unlike the Shenzhou spaceship which has three parts, the new manned spaceship has two parts. One is the part where astronauts come back. The other is the part that gives service. This way of building makes more parts of the spaceship be used again.
