Guowang
Guowang and also referred to as Hulianwang and Xingwang, is a planned Chinese low-Earth orbit satellite internet megaconstellation to create a system of worldwide internet coverage. It was created by CASIC, a firm backed by the CAST. The project was started in 2022 as a rival to the Starlink satellite constellation installed by SpaceX, and plans to be constituted of over 13,000 satellites by the project's end. Since April 2025, the program has launched 14 Hulianwang Jishu Shiyan satellites, 3 Hulianwang Gaogui satellites and 29 Operational Hulianwang Satellites.

Long March 8
Long March 8 () is an orbital launch vehicle developed by the China Academy of Launch Vehicle Technology to launch up to 5000 kg to a 700 km altitude Sun-synchronous orbit (SSO). The rocket is based on the Long March 7 with its first stage and two boosters, along with the existing liquid hydrogen burning third stage of the Long March 3A/ 3B/ 3C and 7A as its second stage. The boosters are omitted in the "core only" variant that first flew on its second launch in February 2022. A planned future launch vehicle variant of the Long March 8 will be partially reusable by featuring a combined booster recovery of the first stage and the boosters as a single unit. The maiden flight of the Long March 8 was launched on 22 December 2020 from the Wenchang Spacecraft Launch Site. CZ-8A variant An upgraded version of the Long March 8, the Long March 8A (), has successfully debuted on February 11, 2025 with increased capability of up to 7 tonnes to a 700 km altitude sun-synchr ...

Long March 6A
The Long March 6A () or Chang Zheng 6A as in pinyin, abbreviated LM 6A for export or CZ 6A within China, is a Chinese medium-lift launch vehicle in the Long March family, which was developed by the China Aerospace Science and Technology Corporation (CASC). The vehicle is a further development of the Long March 6, with two YF-100 engines on the first stage as opposed to one on the Long March 6, augmented by four solid rocket boosters. The Long March 6A is China's first rocket with solid rocket boosters, and only one so far to combine solid and liquid fuel technology in one rocket. There also exists a shorter boosterless variant of the 6A called the Long March 6C. The maiden launch of the Long March 6A took place on March 29, 2022, successfully reaching orbit. It was also the first launch from the newly built launch complex 9A in Taiyuan.

Satellite Internet Constellation
A satellite internet constellation is a constellation of artificial satellites providing satellite internet service. In particular, the term has come to refer to a new generation of very large constellations (sometimes referred to as megaconstellations ) orbiting in low Earth orbit (LEO) to provide low-latency, high bandwidth (broadband) internet service. As of 2020, 63 percent of rural households worldwide lacked internet access due to the infrastructure requirements of underground cables and network towers. Satellite internet constellations offer a low-cost solution for expanding coverage. History While more-limited satellite internet services have been available through geosynchronous commsats orbiting in geostationary orbit for years, these have been of quite limited bandwidth (not broadband), high- latency, and provided at such a relatively high price that demand for the services offered has been quite low. In the 1990s, several LEO satellite internet constel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long March 12
The Long March 12 (), or Chang Zheng 12 as in pinyin, abbreviated LM-12 for export or CZ-12 within China, is a Chinese medium-lift launch vehicle carrier rocket. The manufacturer is Shanghai Academy of Spaceflight Technology. It is capable of placing at least 12 tonnes of payload in low Earth orbit and at least 6 tonnes in a 700 km Sun-synchronous orbit. Its first launch took place on November 30, 2024 from the Hainan International Commercial Aerospace Launch Site on Hainan island. There is also a planned reusable version of the rocket, the CZ-12A; efforts are currently underway to verify stage-reusability technology via vertical take-off, vertical landing (VTVL) tests. Overview On 26 February 2024, the China Aerospace Science and Technology Corporation (CASC) released its annual "Blue Book" which detailed the company's launch plans for the coming year; one of the projects revealed in the Blue Book is the new Long March 12 medium-lift rocket.

Chang'e 6
Chang'e 6 () was the sixth robotic lunar exploration mission by the China National Space Administration (CNSA) and the second CNSA lunar sample-return mission. Like its predecessors in the Chinese Lunar Exploration Program, the spacecraft is named after the Chinese moon goddess Chang'e. It was the first lunar mission to retrieve samples from the far side of the Moon; all previous samples were collected from the near side. The mission began on 3 May 2024 when the spacecraft was launched from Wenchang Space Launch Site on Hainan Island. Its lander and rover touched down on the lunar far side on 1 June 2024. The lander's robotic scoop and drill took samples with a total mass of 1935.3 grams from the lunar surface; the ascender module then carried these into lunar orbit on 3 June 2024. The ascender docked with the orbiter module in lunar orbit on 6 June 2024 and transferred the samples to an atmospheric re-entry module which then returned to Earth. The mission's lander and ...

Geosynchronous Orbit
A geosynchronous orbit (sometimes abbreviated GSO) is an Earth-centered orbit with an orbital period that matches Earth's rotation on its axis, 23 hours, 56 minutes, and 4 seconds (one sidereal day). The synchronization of rotation and orbital period means that, for an observer on Earth's surface, an object in geosynchronous orbit returns to exactly the same position in the sky after a period of one sidereal day. Over the course of a day, the object's position in the sky may remain still or trace out a path, typically in a figure-8 form, whose precise characteristics depend on the orbit's inclination and eccentricity. A circular geosynchronous orbit has a constant altitude of . A special case of geosynchronous orbit is the geostationary orbit (often abbreviated ''GEO''), which is a circular geosynchronous orbit in Earth's equatorial plane with both inclination and eccentricity equal to 0. A satellite in a geostationary orbit remains in the same position in the sky to observers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
