    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.
