China's Space Program News Thread

It must be fake news.

Satellite launches are never launched towards the west which is the direction where Afrika is. (For fuel-saving reason having to do with taking advantage of the spin of the earth)

It’s debris from the earlier failed launch from what I heard. Still scaremongering nonsense, but maybe not 100% fabricated.

That would mean the rocket launcher would have to fly east all the way over North America and going three quarters the way around the Earth and finally landed in Afrika. More likely would be American rocket launcher debris landing on Afrika or Europe but I've never heard of such a thing.

Anybody reading all the articles about how China's CZ-5 launch is a threat to humanity because China can't apparently control the parts that separate from the rocket raining down on the Earth just like what happens with everyone else's when they launch rockets? They even show a picture of what looks like 8-inch piping that that landed in Africa. That didn't burn in the atmosphere? What amazing materials science China must have to be able survive re-entry? Every time they try to spin something from nothing, you know it's all about trying to find an excuse to stop China from advancing.

Average man can't tell lower stage from upper stage of the rocket, which is convenient for taletelling.

I almost believed this bit of fake news after it was reported by major outlets and mentioned by NASA's director. Luckily, the truth was revealed on SDF.

"Free" media lost its mid. lol.

So, the Long March 5B huge single core stage had gone into a very low orbit and spending some time in space.

Normally, a rocket first and second stages fall back to earth within about 1000 km from the launch site.

The point is still is how can a long and thin 40-foot pipe (supposedly from the LM 5B) survive reentry without crumbling up and disintegrating and remaining as straight as it is when it crash-landed in Afrika?

Also it landed on a tree at re-entry velocity and the tree looks almost unscathed

unless they later picked it up and placed it there? Still... then again Ive never seen re-entered space debris and what they look like

The CZ-5 launch is a huge step forward for China hence why they have to vilify it. It will be used to build China's space station while the ISS is coming down to its end. You can imagine how that doesn't sit well with them hence why they want to the world cry out to stop it. If it were just them, it's as petty as it looks.

Forget about reentry. Imagine dropping such a 40 foot long and thin pipe from 10000 feet above the ground. The force of the impact on landing would have crumbled and flattened the pipe.

Final satellite for the Beidou-3 system to be launched next month.

Space Station news:

After the successful maiden flight of the Long March-5B large rocket and the testing of China's new-generation manned spaceship, more details of China's space station have been unveiled.

The space station, expected to be completed around 2022, will operate in the low-Earth orbit at an altitude from 340 km to 450 km for more than 10 years, supporting large-scale scientific, technological and application experiments, according to a report in the People's Daily.

The space station Tiangong, meaning Heavenly Palace, will be able to accommodate three astronauts in normal circumstances and up to six during a crew replacement.

The station will be a T shape with the core module at the center and a lab capsule on each side. Each of the modules will be over 20 tonnes, with the total mass of the station about 66 tonnes, said Zhou Jianping, chief designer of China's manned space program.

If China's Tiangong-1 and Tiangong-2 space labs are like one-bedroom apartments, the space station is equivalent to an apartment with three bedrooms, a living room, a dining room and a storage room, said Zhu Guangchen, deputy chief designer of the space station from China Academy of Space Technology (CAST).

The core module of the station, named Tianhe, has a total length of 16.6 meters, a maximum diameter of 4.2 meters and a takeoff mass of 22.5 tonnes, and is currently the largest spacecraft developed by China.

The Tianhe core module will be the management and control center and the main living space of the crew, and will support some scientific and technological experiments.

The living space in the core module is about 50 cubic meters. Combined with the two lab capsules, the whole living space could be up to 110 cubic meters, according to CAST.

The core module has two berth ports connecting to the two lab capsules, and three docking ports for the crew spacecraft, cargo and other craft. It also has an exit for astronauts to conduct extravehicular activities.

The first lab capsule, named Wentian, will be mainly used for scientific and technological experiments, as well as working and living space and shelter in emergency.

This capsule is equipped with a special airlock chamber to support extravehicular activities and a small mechanical arm for automatic installation and operation of extravehicular instruments.

It possesses some key functions of the core module, which means it can perform the management and control of the space station if needed, according to CAST.

The second lab capsule, named Mengtian, has functions similar to the first lab capsule. It is equipped with a special airlock chamber to support the entry and exit of cargo and instruments with the help of astronauts and mechanical arms.
