China successfully launches first crewed mission for space station construction

It will be China's longest crewed space mission to date and the first in nearly five years.

Beijing/Jiuquan: China successfully launched its longest crewed space mission to date on Thursday, sending three astronauts to its new orbiting station, in a major milestone for the Communist giant’s ambitious space exploration plans and establishing it as a leading space power.

In a textbook launch, telecast live by the official television channels, spacecraft Shenzhou-12 sent three astronauts into the same orbit of the core module of the space station Tianhe launched in April.

About 573 seconds after the launch, Shenzhou-12 separated from the rocket and entered its designated orbit. The Shenzhou-12 crew is in good shape and the launch is a complete success, the China Manned Space Agency (CMSA) announced amid cheers.

Billed as the most prestigious and strategically important space project for China after the country’s recent Mars and previous Moon missions, the low orbit space station would be the country’s eye from the sky, providing round the clock bird’s-eye view for its astronauts on the rest of the world.

After docking with Tianhe, the astronauts, commander Nie Haisheng, 56, Liu Boming, 54 and Tang Hongbo, 45, will stay there for a three-month long mission to carry out the painstaking work of building the space station, which is expected to be ready by next year.

It feels great, Nie, a veteran who took part in two previous manned space missions, said after reaching the near earth-orbit.

It will be China’s longest crewed space mission to date and the first in nearly five years.

China previously sent the space station’s Tianhe core cabin module on April 29, and a cargo spacecraft with supplies on May 29.

The three astronauts, who will build the station, are expected to set a new record for China’s manned space mission duration, exceeding the 33 days kept by the Shenzhou-11 crew in 2016.

The Shenzhou-12 spaceship will conduct a fast-autonomous rendezvous and docking with the in-orbit space station core module Tianhe, forming a complex with Tianhe and the cargo craft. The astronauts will be stationed in the core module.

The spacecraft was launched ahead of next month’s centenary celebrations of the ruling Communist Party of China (CPC) to showcase it as one of its important achievements of China under its leadership.

Considering its political significance, two vice-premiers with responsibility for science and technology, Han Zheng and Liu He, attended the launch event at the Beijing Aerospace Flight Control Centre, besides China’s top military Generals including Defence Minister Gen. Wei Fenghe.

Han and Liu shook hands and congratulated staff after the launch.

Highlighting the space station’s significance, astronaut Nie in his media interaction on Wednesday made no secret that the mission is closely tied with China’s ambition to become a leading space power.

This mission will be the first manned flight as part of the China space station’s construction, said Nie, who has been a Communist Party member for more than three decades.

China’s space exploration development has crystallised the Chinese people’s thousand-year dream of flying to the sky, and added a heroic chapter to the 100-year history of struggle of the [Chinese Communist] party, he was quoted as saying by the Hong Kong-based South China Morning Post.

Once ready, the station is expected to be opened for China’s close allies like Pakistan and for other international space cooperation partners.

Ji Qiming, assistant to the China Manned Space Agency (CMSA) director, told the media on Wednesday that besides close cooperation with Russia, China is also having bilateral cooperation exchanges with countries including France, Italy, Pakistan and others focussing on space experiments in fundamental physics, space medicine and space autonomy on the space station.

More importantly, he highlighted the cooperation with Russia, which is part of the International Space Station (ISS), a collaborative project involving five participating space agencies – NASA (US), Roscomos (Russia), JAXA (Japan), ESA (Europe) and CSA (Canada).

Once ready, China will be the only country to own a space station while the ISS is now a collaborative project of several countries.

It is expected to be a competitor to the ageing ISS and perhaps may become a sole space station to remain in orbit once the ISS retires.

The ISS is divided into two sections, the Russian Orbital Segment (ROS) which is operated by Russia, while the United States Orbital Segment (USOS) is run by the United States as well as many other nations.

China’s space station will be equipped with a robotic arm over which the US has raised concerns for its possible military applications.

The arm, which can be stretched to 15 metres, will also play a vital role in building the space station in orbit, Zhou Jianping, chief designer of China’s manned space engineering project, had said.

Astronauts will team up with the robotic arm to make in-orbit space station construction and maintenance possible.

China, in the past, has launched several scavenger satellites fitted with robotic arms to gather and steer space debris so that it burns up in Earth’s atmosphere.

China plans to send several space missions including with astronauts to carry supplies and materials to complete the construction of the space station.

The space station will operate in low-Earth orbit at an altitude of 340-450 km above Earth’s surface for more than 10 years.

The T-shape station has one core module at the centre and a lab capsule on each side. Each of the modules will weigh over 20 tonnes, with the total mass of the station expected to weigh about 66 tonnes.

Thursday’s launch is China’s seventh crewed mission to space and the first during the construction of China’s space station.

While Beijing showcased the space station as a success, there were also concerns about the debris as China is set to launch several space missions during the construction of the station.

Last month, the debris of Long March-5B Y2 which had launched the core module caused a global stir as it fell back to Earth. Its remnants safely crashed into the Indian Ocean near the Maldives on May 9 with no reports of damage.

The hurtling debris of the rocket evoked sharp criticism from the US, NASA and international astrophysicists, saying Beijing won a reckless gamble. The uncontrolled fall of the rocket stoked fears that it may fall into inhabited areas.

Ji played down concerns, saying that the last stage of all types of launches was treated with passivation technology and will not explode in orbit or generate space debris.

The Shenzhou cargo ship will deorbit and re-enter the atmosphere for destruction after all pre-set tasks are completed in a controlled manner with only minimum wreckage falling into the South Pacific waters,” Ji said.
