China successfully launched its new
heavylift carrier rocket(重型运载火箭) Long March V at 8:43
pm Beijing time, on Nov. 3, 2016. It is the second launch from the Wenchang
Launch Centre.
The rocket, which looked much "fatter"
than other Long March rockets, was launched from the Wenchang Launch Centre in
south China's Hainan Province, About 30 minutes later, it was successfully sent
into an orbit(轨道) about 2, 000 km above the earth.
The major purposes of the task are to check
the design and performance of the new rocket and test the rocket's flight
program. The successful launch has made China from a major player in space to a
major power in space. The successful launch shows that China has become a real
space power in the world.
The Long March V is a large, two-stage(二级的) rocket and one of China's largest carrier rockets. Its carrying capacity
is about 2. 5 times that of the present Long March rockets, which is up to 25
tons.
The rocket is about 57 metres long. It has
eight liquid oxygen rocket engines in four boosters(助推器), two liquid oxygen engines in the first stage and two small liquid
oxygen engines in the second stage.
The new rocket is of great meaning as
China's space program. With the heavy lift carrier rocket, China can send more
astronauts to the space station and get prepared for exploring the Moon and
Mars.
