What Is China’s Tiangong Program? Space Station Plan Strong Despite Tiangong-1 Failure

Ever since its failure was confirmed in late 2015, China’s Tiangong-1 spacecraft has been tracked by organizations to attempt decide where it will fall following reentry, anticipated to happen within the first week of April. While the lack of the module could have been a setback, it hasn’t stopped China from pursuing its formidable purpose of constructing its personal area station, Tiangong.

Translating to “heavenly palace” from Mandarin, the Tiangong program is a daring one, contemplating China was a relative newcomer to the area race however has already established a liveable presence in orbit round Earth. Tiangong-1, earlier than it failed, noticed two visits by crews who frolicked within the module, proving that it was liveable.

The Chinese are following the examined method of constructing an area station one module at a time. Tiangong-1, launched in September 2011, was the primary of these modules, adopted by Tiangong-2, which has been in orbit since September 2016. A cargo spacecraft, Tianzhou-1 (which means “heavenly vessel”), was additionally launched in April 2017, and it efficiently docked with Tiangong-2, demonstrating the success of one other key expertise required to keep up an orbiting laboratory in area.

Tianzhou-1 has a payload capability of as much as six tons and can even refuel Tiangong-2. It carried out two extra dockings with Tiangong-2, one every in June and September 2017.

Two Chinese astronauts (they’re referred to as “taikonauts” regionally) additionally spent 30 days aboard Tiangong-2 in October-November 2016. The module has area for 2 crew members, with its life-support techniques enough to maintain them for 30 days.

There was additionally discuss of launching Tiangong-Three, however the goals of that mission have been merged with Tiangong-2.

However, the core of the deliberate area station, Tianhe-1 (“heavenly concord”), is at present scheduled to be launched someday in 2019, delayed from 2018. This module would have room for 3 crew members, and in addition home the principle management middle. Along with energy, navigation, communication, and life help techniques, the module would even have a docking station and a small robotic arm. Power-generation would depend on two movable photo voltaic panel arrays.

Two laboratory modules are additionally deliberate, presumably to be launched someday between 2020 and 2022. Tentatively referred to as Wentian (“quest for the heavens”) and Mengtian (“dreaming of the heavens”), they are going to present area for researchers to hold out experiments below various stress circumstances, together with zero-gravity. The two modules would additionally dock with Tianhe-1.

But earlier than launching any of those modules, China must will get its launch system so as. Its strongest rocket, Long March-5, failed its second test launch in July 2017, after a profitable maiden take a look at in November 2016. The rocket can carry a payload of as much as 25 tons to low-Earth orbit, and is vital to China’s area exploration tasks. Both Tianhe-1 and the 2 lab modules are scheduled to launch on Long March-5 rockets, as are different missions like these to return lunar samples to Earth and an orbiter and rover for Mars.

If the delivery-to-orbit mechanism is put in place rapidly, the Chinese area station, referred to as Tiangong, could grow to be a actuality by 2023. It could be completely inhabited, just like the International Space Station, with every mission lasting six months.

A deliberate Chinese area telescope — Xuntian (“heavenly cruiser”) — can also be scheduled for launch round 2022, and it could have an orbit close to the nation’s area station.
