Engineer Releases Details About Carried Payload of Long March-7 Rocket
CCTV+
Published on Jun 26, 2016

The scaled-down re-entry capsule of multipurpose spacecraft is the most eye-catching payload carried by the Long March-7 rocket in its maiden flight, said the leader of the re-entry capsule project in an interview ahead of the maiden-launch of the rocket in Wenchang Launch Center in south China's Hainan Province.

"It's approximately 2,600 kg in weight. The width or the diameter is about 2.6 meters. We are testing it to verify if the key technologies of a new generation spacecraft can have the sustaining capacity to send men to the moon, and even to the Mars farther away for exploration like the Shenzhou spacecraft," said Yang Lei, the project leader.

The re-entry capsule is set up onto the silver-colored upper stage spacecraft which is dubbed as "space shuttle bus" and will deliver several payloads to different orbits using its own power system.

China announces success in technology to refuel satellites in orbit
Source: Xinhua 2016-06-30 20:28:19

CHANGSHA, June 30 (Xinhua) -- China has successfully completed the in-space refuel of orbital satellites following last week's launch of a new generation carrier rocket, the National University of Defense Technology announced on Thursday.

Similar to air refueling for planes, the process refuels a satellite in orbit in a microgravity environment and will extend a satellite's functional life and boost its maneuver capabilities considerably.

Developed by the university, Tianyuan-1 is the country's first in-space refueling system for orbital satellites. It was launched into orbit aboard the Long March-7 carrier rocket on Saturday.

A series of core independent processes were tested and verified after the launch, with data and videos recording the full process sent back to earth, the university said in a statement.

"The injection process was stable, and measurement and control were precise," it said, adding that the test proved that Tianyuan-1 met design requirements.

Though an area of great interest, the process is complicated and only a few countries have began experiments.

Nine secrets about China's Long March-7 rocket

2016-06-23 13:54

People's Daily OnlineEditor: Li Yan

According to a subordinate WeChat account of the PLA Daily, Long March-7, China's homegrown new-generation carrier rocket, is scheduled to be launched from the Wenchang Satellite Launch Center in south China's Hainan province between June 25 and 29. This is the first task for the rocket during the construction of the space lab in the third phase of China's manned space flight project. This will be the first time for the Long March-7 carrier rocket to be launched and the first time for the launch center to launch a rocket.

Here are nine secrets regarding the Long March-7 carrier rocket:

1. The new-generation rocket can be launched in the rain

Although China would not launch in-service rockets on rainy days the water-proof new-generation rocket can be launched in rainy days.

As it is of high humidity and precipitation in the new launch center in south China's Hainan province, it is required that the new-generation rocket should be waterproof.

2. The new-generation carrier rocket can be parked for 24 hours after being fueled

The Long March-7 carrier rocket can be parked at the launch center for 24 hours, the longest duration known after a rocket is filled with low-temperature fuel. The new-generation rocket is designed to meet multi-launch demands. The long park duration improve the degree of reliability during launch of the rocket.

3. More water is needed to lower the temperature of the platform during launch.

A total of 400 tons of water is needed during a duration of 20 seconds to lower the temperature of the launching platform so that the platform will not be damaged by the high temperatures.

4. A special protective coating is needed for the rocket launch platform.

As the temperature will reach 2,800 degrees Celsius at the moment of launching, technicians will paint a special protective coating on the platform to extend the service life.

5. The Long March-7 carrier rocket has been shipped to the launch center from the Tianjin port rather than being transported along highways and railways.

6. In order to save space, the new-generation rocket will use the same track as the Long March-5 did during transportation. The rocket will make 60-degree turns four times.

7. There are pipes used to refuel, recharge and adjust the temperature of the rocket.

8. Almost 90 percent of the weight of the rocket is fuel.

9. The new-generation rocket can resist sudden gales of wind because the rocket is equipped with wind-resistance devices.
