    The question is why hasn't the altogether more modern Long March 7 been man rated allowing it to replace the 2F and its toxic fuel loads?

    The other night, I was able to see the ISS and the Chinese space station module, at the same time. ISS was much brighter. I'm wondering how bright the Chinese station will be when it's complete?

    "Tianzhou spacecraft launches, heads to space station"

    http://www.chinadaily.com.cn/a/20210...d0bac251d.html

    Tianzhou 2, the first spacecraft to visit the recently deployed core module of China's Tiangong space station, was launched on Saturday evening and is scheduled to dock with the module soon.

    Tianzhou 2, a robotic cargo ship, flew with a Long March 7 carrier rocket that blasted off around 8:50 pm at a coastal launchpad at the Wenchang Space Launch Center in the southernmost island province of Hainan.

    After a 10-minute flight atop the 53-meter rocket, the craft entered a low-Earth orbit and soon unfolded its solar panels, entering the operational mode, according to the China Manned Space Agency.

    The agency said the cargo ship will rendezvous and dock with the currently unmanned core module in a matter of hours and then conduct autonomous refueling and cargo placement operations.

    China has been more forthcoming in describing the problems they had with LM-7.

    https://www.globaltimes.cn/page/202105/1224812.shtml

    Following the announcement of the successful launch, the People's Daily disclosed Saturday that on May 20, within less than four hours of the planned launch, which was planned at around 1:30 am, the ground command center found a parameter indicating pressure levels returning abnormal data, indicating that the rocket could no longer meet the launch requirements.

    Research teams then decided, without hesitation, to delay the launch, two hours before the planned schedule.

    Research teams were dispatched immediately to check system functions, while the command center prepared for an attempt to recover the mission, which had been set to a day later in the early morning of May 21.

    However, after liquid oxygen was refueled eight hours before the scheduled launch time, abnormal signals once again occurred.

    China has put its technology to use, to manage the cargo in the space station.

    http://www.xinhuanet.com/english/202..._139978794.htm

    Engineers have designed a special structure in the 18-cubic-meter cargo craft, dividing the interior into cargo compartments with honeycomb-like panels. Each compartment can hold several packages of different sizes, so that the packages can be efficiently placed in the compartments like building blocks.

    To improve the efficiency of loading, the research team has made 26 types of packages of different sizes, including some in trapezoidal and wedge shapes to adapt to the cylinder cabin structure of the craft. In addition, they have developed safety locks, similar to those of aircraft seats, to hold the packages in position while in space.

    The craft is also equipped with an information-management system. Each package has a label pasted onto it with a radio-frequency identification function, allowing the goods to be identified within a certain range.

    Yang Sheng, a designer of Tianzhou-2 at the CAST, said that China's space station has applied the country's advanced logistics-management technologies, enabling astronauts to obtain the cargo location and information by scanning QR codes. With intelligent positioning, the astronauts can find and access the packages quickly.

    "How China’s space station could help power astronauts to Mars"

    https://www.scmp.com/news/china/scie...stronauts-mars

    China’s Tiangong space station could help pave the way for a manned mission from Mars with its use of a propulsion system that has never before been used on manned spacecraft.

    The space station’s core Tianhe module is powered by four ion drives – also known as Hall effect thrusters – a form of electronic propulsion that has been around for decades and could dramatically slash the time needed to travel to the Red Planet.
    The four ion drives that power the Tianhe module, which is expected to welcome its first astronauts later this month, are small compared to rocket engines but they are incredibly efficient.

    The International Space Station, for instance, consumes over four tonnes of fuel annually to stay in its near-earth orbit. If powered by ion thrusters, its consumption would drop to 400kg, requiring just one refuelling mission a year, according to the Chinese Academy of Sciences.

    "Effective power supply energizes China's space station project"

    http://www.xinhuanet.com/english/202..._139999119.htm

    Highly efficient power supply has kept the combination of the Tianzhou-2 cargo craft and China's space station core module Tianhe operating stably.

    China sent into space the Tianhe module on April 29, kicking off a series of key launch missions that aim to complete the construction of the space station by the end of 2022.

    The country launched Tianzhou-2 on May 29, which successfully docked with Tianhe in about eight hours to deliver supplies, equipment and propellant.

    Both the core module and cargo craft are equipped with independent power supply systems. After docking, the two systems can form a connected grid and achieve mutual transmission of electric power.

    "China ready to launch first crew to new space station"

    https://www.spacedaily.com/reports/C...ation_999.html

    The first crew for China's new space station prepared to blast off this week for the latest step in Beijing's ambitious programme to establish itself as a space power.

    The mission is China's first crewed spaceflight in nearly five years, and a matter of prestige for the government as it prepares to mark the 100th birthday of the ruling Communist Party on July 1 with a propaganda blitz.

    A Long March-2F rocket carrying three astronauts in the Shenzhou-12 spacecraft is slated to lift off from a base in northwest China's Gobi desert on Thursday, according to experts with knowledge of the matter.

    The New York Times on China's launch. It also covers other aspects of the launch and future plans. It end with what the USA is doing with the ISS.

    https://www.nytimes.com/2021/06/16/s...e-station.html

    There will soon be two places in orbit where astronauts live.

    On a clear, sunny Thursday morning in the Gobi Desert, China launched three astronauts to rendezvous with the country’s nascent space station.

    They waved to cameras in their capsule as their trip to space began. Twenty-one minutes into the mission, the director of the launch center, Zhang Zhifen, announced that it was “a complete success.”

    Nice to see so much video available.

    I watched the launch. Good coverage too. I suppose their countdown is timed differently to how we do it because by the time it got to zero, I thought there had been an abort. Of course it did fire and we got some inside the cabin video.

    Good job.

    CGTN (is funded in whole or in part by the Chinese government.) on the CSS. A 22 minute video.

    https://www.youtube.com/watch?v=bcZ3GorY6fA

    To infinity and beyond – China's Shenzhou-12 spacecraft blasted off from Jiuquan in northwestern China on Thursday morning. This time, a crew of three – Nie Haisheng, Liu Boming and Tang Hongbo – are on board for a three-month visit to China's space station. The Shenzhou-12, which means "Divine Vessels," is the third of 11 missions China planned to complete its space station. Over the last decades, China has sent 11 astronauts into space. This manned mission is the first time China has sent humans into space in nearly five years. Crew members will live on the Tianhe, "Harmony of the Heavens," and the planned three-month stay would set a new record for all Chinese astronauts. With China forging ahead with its space exploration program, what lies ahead for the crew of three in putting the finishing touches on the country's space station? How well can they carry out their mission?

    The article contains the layout of the space station.

    https://www.thedrive.com/the-war-zon...ambitions-grow

    China successfully placed its first crew members aboard its Tiangong space station, which is still under construction. Three taikonauts (astronauts) boarded the Tianhe core space station module in orbit, marking a new milestone in the Middle Kingdom’s rise as a global leader in space. While the launch of the Shenzhou-12 mission is significant on its own right as a demonstration of China’s space program, it also highlights growing concerns about Chinese ambitions in space.

    The Shenzhou-12, or “Divine Boat” mission, is the seventh crewed Chinese spaceflight in history and China's first space manned mission since 2016. Three astronauts, Commander Nie Haisheng, Liu Boming and Tang Hongbo, took off aboard a Long March 2F rocket launched from the Jiuquan Satellite Launch Center in Inner Mongolia on June 17. Seven hours after launch, the crew successfully docked with the Tianhe module in low Earth orbit (LEO) at an altitude of around 236 miles.

    "Astronauts arrange new 'home' in space"

    http://www.chinadaily.com.cn/a/20210...baca15b_1.html

    Astronauts on board the core module of China's space station have started to prepare their orbiting residence for operations over the next three months.

    As soon as the three crew members-Major General Nie Haisheng, Major General Liu Boming and Senior Colonel Tang Hongbo-floated into the core module, named Tianhe, or Harmony of Heavens, on Thursday afternoon, they started to configure the electrolytic oxygen generators, install water tanks and arrange their sleeping quarters, according to the China Manned Space Agency.

    After finishing these tasks, they enjoyed their first sleep on board the module, the biggest spacecraft China has built and the first and central section of the permanent space station, called Tiangong, or Heavenly Palace.
