India too is geared up for 2 mission per month. India will carry record numbers of satellites. Most of Indian missions carry multiple satellites in single mission including satellites to be put in different orbits. Since India can launch such complex missions, launch cost can be minimized. India' SSLV will reduce launch cost by 10% of current cost of launch of India which is already cheaper by 40 to 50% any where. SSLV will be ready within a week for a launch.

China's heaviest satellite positioned in geosynchronous orbit
Xinhua, January 6, 2020
Adjust font size:

China's heaviest and most advanced satellite, Shijian-20, reached its fixed position in geosynchronous orbit Sunday, marking the first successful flight of DFH-5 satellite platform, according to the China Aerospace Science and Technology Corporation.

The Shijian-20 satellite is the first verification satellite for DFH-5 satellite platform, China's new generation of large geosynchronous orbit satellite platform.

At present, the satellite has completed the orbit transfer and verified the key technologies of the DFH-5 satellite platform, according to Li Feng, chief designer of the satellite.

The Shijian-20 satellite was launched into space by the third Long March-5 rocket, China's largest carrier rocket on Dec. 27, 2019. It has carried out orbit experiments for a series of key technologies.

Shijian-20 has the largest solar wings among all China's satellites, with the total wingspan 10 meters wider than that of a Boeing 737 aircraft. The solar wings has unfolded twice, and the increased solar wing area will supply the satellite with abundant power.

Compared with the DFH-3 and DFH-4 satellite platforms, the DFH-5 satellite platform has improved in weight, power and in-orbit lifespan, which will serve the needs of high-capacity satellites in the next 20 years, said Zhou Zhicheng, chief engineer of the DFH-5 satellite platform.

2019 marked another year of accomplishments for China – here are some of the many achievements of the past 12 months that made Chinese people especially proud of their nation

Chang’e 4 makes the first landing on the far side of the Moon
The Chang’e 4 lunar probe landed at 10.26am on 3 January on the Von Karman crater in the South Pole-Aitken basin, making the first-ever landing on the far side of the Moon.

China’s lunar rover Yutu 2 drove 345m (1,132ft) on the far side of the Moon, a new record for the furthest distance ever made by a rover, the Lunar Exploration and Space Programme Centre of the China National Space Administration said on 4 December.

The rover is expected to continue to break its own record as its lunar journey continues.

Maglev train prototype with top speed of 600km/h unveiled
China unveiled a prototype magnetic levitation train with a designed maximum speed of 600km/h (about 373mph) in Qingdao, Shandong province, on 23 May.

The debut of the prototype marked a major breakthrough by China in high-speed maglev trains. The engineering prototype is expected to roll off the production line this year and to undergo comprehensive testing and be made ready for commercial manufacturing in 2021.

They include space life sciences and biotechnology, microgravity physics and astronomy, the China Manned Space Agency and the United Nations Office for Outer Space Affairs announced on 12 June in Vienna, the Austrian capital.

China’s space station is expected to be completed in 2022. It will serve as a space laboratory to carry out multidisciplinary scientific research, technological verifications and applications.

FAST telescope picks up “mysterious radio burst” for first time
China’s Five-hundred-metre Aperture Spherical Radio Telescope(FAST) has detected a repeating fast radio burst (FRB) – a mysterious radio signal from space – for the first time. The FRB originated about three billion light years away from Earth, scientists on the FAST project revealed on 4 September.

FRBs are one of the hottest topics in astronomy – the first FRB was detected in 2007. Fewer than 100 FRBs have been detected internationally to date.

The move means consumers can now pay to access superfast 5G speeds as more than 86,000 5G base stations have already entered service in China, covering 50 cities nationwide.

China is set to become the world’s largest 5G market by 2025, with 460 million 5G users, according to a forecast by the Global System for Mobile Communications Association, a global telecom association.

China-led team discovers biggest stellar black hole
An international team of scientists led by China has discovered a king-size stellar-mass black hole in Earth’s “cosmic backyard” containing the mass of 70 suns. It is the biggest known of its kind and about three times bigger than what scientists previously thought was possible, researchers said on 28 November.

The black hole, named LB-1, was found slowly devouring gas from a nearby star more than 13,800 light years from Earth, relatively nearby, considering the estimated 105,700 light-year diameter of Earth’s galaxy.

LB-1 was first spotted by Chinese scientists in 2016 using spectrum data collected by the Large Sky Area Multi-Object Fibre Spectroscopic Telescope. An international team of 55 scientists from 28 research institutions in seven nations, including China, the United States and Spain, have worked together in the past three years to confirm the discovery.

Core of Beidou navigation satellite network in place
With the last two medium Earth orbit satellites of the Beidou’s third-generation system launched on 16 December, China has finished the deployment of the core constellation of its Beidou Navigation Satellite System.

Currently, there are 46 Beidou satellites in service in space. The China Satellite Navigation Office intends to position two more Beidou satellites in geostationary orbit in the first half of 2020 to finish the deployment of all of Beidou’s space-based assets.

Beidou is China’s biggest space-based system and is one of four space-based navigation networks, along with the United States’ GPS, Russia’s Glonass and the European Union’s Galileo.

China’s first launch of 2020 lofts mystery payload
January 7, 2020


A Long March 3B rocket lifts off Tuesday with the TJS 5 satellite. Credit: People’s Daily

A Chinese Long March 3B rocket launched a satellite Tuesday toward a position in geostationary orbit more than 22,000 miles (nearly 36,000 kilometers) above Earth. Chinese state media claimed the mysterious spacecraft has a communication and television broadcast mission, but analysts believe it could enter service for the Chinese military.


The Long March 3B launcher lifted off from the Xichang space center in southwestern China’s Sichuan province at 1520 GMT (10:20 a.m. EST; 11:20 p.m. Beijing time) Tuesday, Chinese state media reported.

Four liquid-fueled strap-on engines gave an extra boost to the three-stage, 184-foot-tall (55-meter) rocket as it arced toward the east from Xichang, setting off on China’s first satellite launch of 2020.

The Long March 3B’s third stage was expected to deploy the satellite, designated TJS 5, into an elliptical geostationary transfer orbit with an apogee, or high point, stretching more than 22,000 miles above Earth.

Chinese state media declared the launch was a success. U.S. military tracking data later confirmed the satellite was deployed into the expected orbit.

The TJS 5 satellite is the fifth in a line of Chinese missions that have intrigued Western analysts. The first TJS satellite launched in 2015, and the timing and circumstances of the TJS 5 launch suggest a similarity with the deployment of the TJS 5 spacecraft in January 2017.

The TJS 2 and TJS 5 satellites were both manufactured by the Shanghai Academy of Spaceflight Technology, according to Chinese media reports. And both satellites launched from Xichang atop Long March 3B rockets in early January, with liftoff times separated by just two minutes.

Chinese state television said that TJS 5 satellite will support communications, television broadcast, data transmission and other services. But China’s government-run media apparatus often identifies the owner or end user of the country’s other satellites.

That was not the case with the TJS series of satellites.

Analysts speculated the TJS 2 satellite launched in 2017 may have a military mission, such providing as missile detection and early warning services to the Chinese armed forces.

Like the TJS 2 spacecraft, the TJS 5 satellite is expected to use its own thrusters to maneuver into a circular geostationary orbit nearly 22,300 miles (35,800 kilometers) above the equator.

Tuesday’s launch was the first of more than 40 Chinese satellite deployment missions planned in 2020, following a busy 2019 that saw Chinese rockets perform 34 orbital launch attempts, with 32 successes.
