CHONGQING, Feb. 5 (Xinhua) -- A new smart suborbital rocket developed by a private Chinese company was successfully launched from a site in northwest China on Friday, according to the company.

The "Chongqing Liangjiang Star" OS-X6B, with a length of 9.4 meters, was launched at 5:05 p.m. It completed a flight time of about 580 seconds, reaching a maximum altitude of about 300 km, said OneSpace Technology Group Co.

The launch marks the first time that a private Chinese rocket company has realized controlled re-entry flight, human-in-the-loop space flight control, and (upper stage) redundant fault-tolerant control, according to OneSpace.

It also completed the verification of a number of key technologies and obtained a large amount of real flight environment data.

Established in 2015, the Beijing-based OneSpace is China's first private company with a license to develop carrier rockets, with a manufacturing base in southwestern Chongqing Municipality.

China's Tianwen-1 probe enters orbit around Mars

BEIJING, Feb. 10 (Xinhua) -- China's Tianwen-1 probe successfully entered the orbit around Mars on Wednesday after a nearly seven-month voyage from Earth.

A 3000N engine was ignited at 7:52 p.m. (Beijing time) to decelerate Tianwen-1, according to the China National Space Administration (CNSA).

After about 15 minutes, the spacecraft, including an orbiter, a lander and a rover, had slowed enough to be captured by Mars' gravity and entered an elliptical orbit around the red planet, with its closest distance from the Martian surface at about 400 km. It will take Tianwen-1 about 10 Earth days to complete one circle.

The development marks China's completion of a key step in its current Mars exploration program, which is designed to complete orbiting, landing and roving in one mission, said the CNSA.

After entering the Mars orbit, payloads aboard the orbiter, including cameras and various particle analyzers, will next start working and carry out surveys of the planet.

Tianwen-1 was launched via a Long March-5 rocket, China's largest launch vehicle, from the Wenchang Spacecraft Launch Site on the coast of southern China's island province of Hainan on July 23, 2020.

Tianwen-1 has been traveling in space for 202 days. It has carried out four orbital corrections and a deep-space maneuver. It has flown 475 million km and was 192 million km from Earth when it reached the Mars orbit.

A steerable radio telescope with a 70-meter-diameter antenna in Wuqing District of northern China's Tianjin City is a key facility receiving scientific data sent back by the Mars probe. The one-way communication delay is about 10.7 minutes.

Tianwen-1 will now conduct multiple orbital corrections to enter a temporary Mars parking orbit, surveying potential landing sites in preparation to land in May or June.

China launches new satellites to survey electromagnetic environment on February 24, 2021
The third group of China's #Yaogan-31 remote sensing satellites were sent into space from the Jiuquan Satellite Launch Center in northwest China at 10:22 a.m. (Beijing Time) on Wednesday. Having entered their planned orbits, the satellites will be used for electromagnetic environment surveys and other related technological tests.

China makes new breakthrough in heavy-lift carrier rocket engine
Source: Xinhua | 2021-03-05 20:13:27 | Editor: huaxia

BEIJING, March 5 (Xinhua) -- China on Friday successfully conducted a trial run on a 500-tonne-thrust liquid oxygen (LOX) and kerosene rocket engine, according to the China Aerospace Science and Technology Corporation (CASC).

It marks a new breakthrough in the country's rocket-engine technologies, and will lay a solid foundation for its follow-up development of the heavy-lift carrier rocket, said the developer.

The new engine, with its design and management fully digitalized, provides three times the thrust of a 120-tonne-thrust LOX kerosene high-pressure staged combustion engine, the CASC said, adding that its comprehensive performance indicators are equal to the best in the world.
