Expert from China: It will be difficult for Russia to make launches at Tiangong.

Yang Yuguang: It will be difficult for Russia to launch to the Tiangong space station.

17:10 10.05.2022

BEIJING, May 10 - RIA Novosti. In the future, other countries will be able to send spacecraft to China's Tiangong Orbital Space Station, but Russia will face difficulties in launching ships due to the geographical location of the spaceports, said Vice Chairman of the International Astronautical Federation's Space Transportation Committee, professor at the China Aerospace Science and Industry Corporation (CASIC) Yang Yuguang.

According to him, in the future it may be possible to launch spacecraft to the Chinese orbital space station from other countries.

“Speaking of Russia , there is one factor that we must take into account. The territory of Russia is located at very high latitudes, and for docking with the Chinese space station, we have a basic requirement: the latitude at which the launch pad is located must be no higher than 42 degrees, this is the difficulty that Russia will face," Yang Yuguang said on Chinese TV channel CGTN on Tuesday.

At the same time, Yang Yuguang noted that the United States , Japan , as well as the EU countries that operate the Kourou cosmodrome in French Guiana , will not face such difficulties.

China's Tianzhou-4 spacecraft successfully docked at the Tiangong station on Tuesday. The truck delivered fuel, equipment, consumables and other cargo into orbit for the Shenzhou-14 crew of three, who will go to the Tiangong station in June this year and spend about six months there.

The construction of the Chinese multi-module orbital station Tiangong officially began on April 29, 2021, when the main module Tianhe was successfully launched into orbit. The construction of the station is expected to be completed this year. Three cosmonauts can be on the station at the same time, or six people during a crew change.

It is planned that the Wentian laboratory module and the Mengtian research module will dock to the station this year. In addition, in 2025, the autonomous astrophysical module "Xuntian" should be launched, which will periodically dock with the station for maintenance.

The main module of the station with a length of 16.6 meters and a maximum diameter of 4.2 meters was named "Tianhe", at the moment it is the largest spacecraft built in China . The control and management center and the main living space for the crew (about 50 cubic meters) are located here, and some scientific and technological experiments will also be carried out here.

In addition to the main module, living space is also provided in the experimental ones, so its total area will be about 110 cubic meters. The main module is equipped with two docking stations for experimental compartments, as well as three docking ports for docking manned and cargo ships.

Its a lot of work, but an option for Russia is to get Soyuz-5 launching Oryol from the old Zenit sea launch pad.

Tianzhou-3 deorbit burns will happen after the launch and docking of Wentian Laboratory Module, so it will fly with Tianhe Core Module for at least one more week, not just few days. What jobs will the cargo spacecraft do during this period? Can it assist Wentian docking?

According to a post by CASC, the relocation of Wentian Lab Module from the forward to starboard port will happen ~1 month before the launch of Menttian. Wentian measures 17.9m in length, 4.2m in width. 50m^3 pressurized volume hosting 8 research racks, among which 4 belong to CAS..

1 probably to ACC, and the remaining 3 are probably empty shelves to host customer payloads.

The newly-installed CO2-reduction ECLSS (basically a Sabatier reactor) has produced 22L of water in about a month's worth of operations:

A post by ChinaDaily & Our Space, cited @TricLarose's tweet of conducting #TumorsInSpace research in #Tiangong, adding "Dr Larose is currently taking training as a payload specialist. She's expected to board the China Space Station in 2025-2026". It seems an official recognition..

Watch an interesting video: CSS Intelligent Induced Maintenance System. The video simulates the astronaut wearing AR glasses, and according to voice, animation and text guidance, initializes and unlocks the "mobile maintenance platform" of the Mengtian experimental cabin "online maintenance and adjustment operation cabinet MMW". *This MMW cabinet is in Mengtian, not Wentian's scientific glove box and cryogenic storage cabinet GCSR. These two cabinets look a bit similar, don't mix them up.

Mobile maintenance platform - expand the operating area, support large-load on-orbit maintenance operations, and carry out popular science education activities... MMW is a cabinet used to repair experimental cabinets. Astronauts cannot fully understand the maintenance of each hardware of the space station, so CAS/ CSU designed this intelligent induced maintenance system to help astronauts do their jobs easily. In the future, the system will also add a real-time expert system.

What should we call this in English?

Maintenance & Malfunction Workstation?
Mobile Maintenance Workstation?

good morning. This morning is #CSS #Tiangong in Nagoya (Chinese space station #TIANGONG ). It grew and became smaller for a while, but before dawn on the 25th, the new experimental building module #Qianten docked and became like a space station at once.

"Designing objects to disintegrate upon atmospheric re-entry is becoming a priority for satellite operators. It's done partly by using materials which have low-melting point temperatures, such as aluminium.

In the case of rockets, this can be expensive, as historically the materials used for housing fuel, such as titanium, require very high temperatures to burn up. The sheer size of such objects is also an issue, especially in the case of the Long March 5, weighing over 25 tonnes."

Expensive?
