China has begun development of a big multi-module area station with the launch of the Tianhe core module, beginning a interval of fast launches to assemble the outpost by 2022.
Liftoff atop a Lengthy March 5B heavy-lift rocket occurred at 11:23 p.m. EDT April 28 (03:23 UTC April 29), 2021, from the Wenchang Spacecraft Launch Web site in Hainan, China. It was the second flight for the 54-meter-tall “5B” variant and it took about eight minutes to achieve its preliminary trajectory in low Earth orbit to launch Tianhe, which is Chinese language for “concord of the heavens.”
About an hour after being deployed into orbit, the core module’s photo voltaic panels had been deployed. In some unspecified time in the future, its onboard engines are anticipated to circularize its orbit to round 370 kilometers.
Just like the Russian Zvezda module on the ISS, Tianhe is 16.6 meters lengthy (some three meters longer than Zvezda) and about 4.2 meters in diameter at its widest. Its mass is about 22 metric tons.
Tianhe is to function the station’s command and management hub. It has a single docking port on its aft part and 4 ports on the ahead sphere. Additionally on the ahead sphere is an airlock hatch for spacewalks.
Based mostly on the nation’s earlier area station program testbeds, the single-module Tiangong-1 and Tiangong-2 (Tiangong is Chinese language for “heavenly palace) in 2011 and 2016, the brand new modular outpost is China’s reply to the multinational Worldwide House Station. When accomplished, it’ll be shut in dimension to the Russian Mir area station, which orbited Earth between 1986 and 2001.
That is the primary in a sequence of launches to finish the station by late 2022. A further 10 missions are deliberate to finish meeting. This contains crew and cargo missions in addition to two extra laboratory modules.
As of proper now, the following launch for meeting is anticipated to be the Tianzhou-2 (Chinese language for heavenly ship) automated cargo spacecraft, probably in late Could 2021. It’ll probably dock with both the aft or the ahead port of Tianhe. The cargo spacecraft is predicated on the preliminary Tiangong stations and upgraded to function resupply freighters.
From there, the crewed Shenzhou 12 mission will launch with three “taikonauts” — Nie Haisheng, Deng Qingming and Ye Guangfu — to remain aboard the brand new outpost for a number of months.
Shenzhou 12 will solely be the seventh human spaceflight carried out by China since its first in October 2003, and the primary since 2016.

Over the following 12 months, a number of autonomous Tianzhou and crewed Shenzhou missions will happen to construct up the outpost. Two laboratory modules are slated to launch someday in 2022.
The area station might be constructed in orbit in a “T” form configuration with the 2 extra modules, every 14.Four meters lengthy.
Taikonauts and probably astronauts from different nations are anticipated to make use of these the laboratory modules to conduct scientific experiments in orbit just like astronauts and cosmonauts on the ISS.
The primary module known as Wentian (quest for the heavens) and the second is Mengtian (dreaming of the heavens).
These might be connected to the Tianhe core module, initially on the ahead port earlier than a small arm will transfer it to both the port or starboard facet.
In some unspecified time in the future, China is anticipated to launch a Hubble-class telescope referred to as Xuntian (heavenly cruiser) which can co-orbit with the Chinese language area station. It’s launch is anticipated in 2024 and it is going to be in a position to periodically dock with the outpost for upkeep and upgrades.
