The first Long March 5B carrier rocket arrived at the Wenchang Space Launch Center in Hainan province on Wednesday for prelaunch preparations.
The rocket's components were carried by two rocket transportation ships – Yuanwang 21 and Yuanwang 22 -- from Tianjin, a northern coastal municipality and home to the launch vehicle's manufacturing complexes. It spent about a week on the trip to the southernmost island province, according to the China Academy of Launch Vehicle Technology in Beijing, the leading rocket developer in the country.
Long March 5B is the first variant of the Long March 5, which conducted its third mission at the Wenchang center in December. It will be tasked with sending large spacecraft to low-Earth orbit, the academy said in a statement.
The rocket is 53.7 meters long, with a diameter of 5 meters. It will be propelled by liquid oxygen, liquid hydrogen and kerosene and will have a liftoff weight of about 849 metric tons.
Li Dong, the rocket's chief designer, said that the craft will be pollution-free and will be the most powerful rocket when it comes to carrying capacity to the low-Earth orbit – it will be capable of placing 22 tons of payloads in such an orbit.
The designer said research and development of the rocket started in 2012, adding that the first Long March 5B passed quality examination on Jan 19.
At the launch center, the rocket will make ground drills with the prototype of the Chinese space station's core module to verify the launch sequence for the space station. After the drills, it will carry out the debut flight in April to launch the prototype of the country's new manned spaceship, said the China Manned Space Agency.

China's Long March 5B Space Station Transport Rocket Reaches Launch Site
(Yicai Global) Feb. 6 -- China's rocket designed and produced solely for construction of the country's pioneering space station, the Long March 5B, arrived yesterday at its launch site in Wenchang in the country's southernmost province, the tropical island of Hainan.
The vessel will blast off in mid-April carrying the latest-generation experimental manned space module for its maiden voyage.
China plans to start building its space station this year. The facility, whose eventual weight will be 90 tons, has a designed lifetime of ten years. Its completion in or around 2020 will need 12 launch activities. The country's manned complex in the sky is a essentially a laboratory assembled in orbit that will be able to conduct relatively large-scale experiments.
The new rocket, the latest in the space-faring nation's Long March 5 series, specially adapted to undertake the varying tasks required for construction of the orbiting facility China is creating in the heavens, will primarily carry the cabin module, manned spacecraft and cargo shuttle aloft.
The rocket, whose body measures 53.7 meters in length and has a diameter of five meters, uses non-toxic, pollution-free liquid oxygen, liquid hydrogen and kerosene as propellants. It has a lift-off weight of 849 tons and is able to bear a further 22 tons of freight at a minimum into near-Earth orbit.
The Long March 5B will now go through pre-launch full dress rehearsals together with the Tianhe core space station module and manned craft that reached the Wenchang site on Jan. 20 before their joint mission begins in earnest in the spring. The Tianhe capsule can accommodate three taikonauts, as China dubs its space explorers.

Maiden launch scheduled for 27th December 2019
2019-12-26 08:58:31
The promotion of the space technology companies in Taitung ’s space exploration rocket has attracted attention from all walks of life. However, due to local concerns, the launch operation will be suspended and a briefing will be held today. The relevant person said today that the promotion company hopes to obtain local public opinion supports and strives to launch as scheduled tomorrow (27th). If the planned launch operation can be carried out according to the original plan, the projectiles of the space exploration rocket will fall into the waters 30 kilometers east of Green Island and Lanyu.
Relevant sources also said that if it is difficult to successfully launch on the 27th of this month, the next launch date will be on January 22 next year.
The Maritime Safety Administration, the Agriculture Commission, the Civil Aviation Bureau of the Ministry of Communications, the Port Bureau and the military have issued sea and air area control notifications in accordance with previous plans, calling on vessels and aircraft in various areas to avoid the controlled sea and air areas launched by rockets.
The promotion company had previously stated that once the space exploration rocket was launched, the entire rocket had a range of about 10 minutes and fell after reaching 200 kilometers. However, according to the application file of the promotion company, the maximum ballistic altitude of the space exploration rocket was 300 kilometers. A space exploration rocket can reach a higher altitude. If the rocket launches smoothly, the small satellites carried next time will be able to be sent directly into space orbit.
In order to perform the launch mission of the National Space Center's multi-purpose sounding rocket scientific experiment, the promoted space technology company once invited the relevant units to coordinate the sea and airspace control operation. According to the launching notice (sea and airspace) issued by the Coastal Inspection Agency and the Agricultural Committee Control sheet), from 6 am to 7 am on the 27th, it will be launched at the Taidong Nantian launch base (台東南田發射基地). The rocket's projectiles are expected to fall in the waters 30 kilometers away from the middle of Green Island and Lanyu.

Abnormal guidance system's signal: 2nd Hapith-I launch attempt scheduled for 18th February 2020
2020/02/13 08:23
TiSpace Corporation, Taiwan ’s first private company’s self-made sounding rocket 'Flying Squirel One' was originally expected to test fire at 6 am in Nantian, Daren Township, Taitung County.
The launch procedure was already started when at the last minute, an abnormal system signal was detected. Finally, the launch procedure was aborted, and the NO2 fuel was released into the air, disappointing hundreds of people who came to watch the rocket maiden test launch.
The company also stated that it would try to launch the rocket again after finding the cause.
TiSpace company built a base to launch a test rocket around the Nantian tribe. The news was disclosed last December. The tribe residents expressed their dissatisfaction, strongly questioning the legitimacy, and worried about the danger posed to the tribe's security and environmental ecology. Later, the central government came forward to solve the decree, and Tispace has also been intensively communicating with localities for more than a month.
There was a heavy rain on the scene this morning, but it did not quench the enthusiasm of hundreds of people. Everyone made a special trip to get ready to enjoy the wonderful picture of the first domestic private company's test rocket launch, but they were disappointed.
Taking pictures of the rocket outside, Tispace company said that it is expected to conduct another test launch in the early morning of February 18th.

The weather was of the worse, with storm all the previous night. Then high altitude wind would even burst weather balloons released at dawn by the meteorologists.
Finally the decision was taken to go ahead with the maiden launch of Hapith-I sounding rocket.
After ignition, an abnormal signal was detected, and decision to cutoff the engines at ~20 seconds, aborting the takeoff.

@Viet @MacanJawa
This is the pivotal point when rating China.
Most people simply don't understand that what makes China a true superpower, is not its judicial system, its social system, its education and healthcare, not even its economy.
It can not be quantified with GDP figure, and the quality of its exported products, nor the sturdiness of its buildings and infrastructures.
It is not related to the civic-mindedness, morality and virtue of its citizens. Nothing to do with the personal hygiene and food hygiene of its population.
Otherwise, as those who make the gross mistake, Denmark or Singapore should be considered as superpowers instead.
Born under the most violent military assaults that humankind has ever witnessed, the CPC has survived the largest scale biowarfare unleashed by the Empire of Japan from the 1937 onwards, and this right after the historical 12,500 km Long March that saw the Red Army retreating and thus escaping an annihilating encirclement waged by German Nazi Generals in their Eastern Jiangxi strongholds in the early 1930s.
Having survived until the end of the Second World War, as victor who received the surrender of the Empire of Japan in 1945, the CPC has emerged as the top military organization in the world.
Today, in peace time, the PRC can face any outbreak of epidemy, while conducting unshattered all its military developments as scheduled.
The PRC is the most successful military-industrial complex in the world, that has even outbeaten the Soviet war machine (who lost the cold war). This is what makes the PRC a superpower. Not the management of its civilian society, that is not an example for mankind.

Construction of China's space station about to start
Source: Xinhua| 2020-02-20 11:20:43|Editor: huaxia
BEIJING, Feb. 20 (Xinhua) -- The maiden flight of the Long March-5B rocket carrying a trial version of China's new-generation manned spaceship is expected to take place in April, indicating the imminent start of construction of China' space station.
The rocket, the prototype core capsule of the space station and the experimental manned spaceship are undergoing tests at the Wenchang Space Launch Center on the coast of south China's island province of Hainan.
During the flight in mid to late April, the experimental manned spaceship will be sent into space with no crew. The prototype of the core capsule of the space station will not be launched.
The Long March-5B is a modified version of the Long March-5, currently China's largest carrier rocket, and will be mainly used for sending capsules of China's space station and large spacecraft to the low-Earth orbit, according to the China Manned Space Agency (CMSA).
Space engineers developed a new large fairing, which is 20.5 meters long and 5.2 meters in diameter, for the Long March-5B. The whole rocket is about 53.7 meters long, with a 5-meter diameter core stage and four 3.35-meter diameter boosters.
The rocket uses environment-friendly fuel, including kerosene, liquid hydrogen and liquid oxygen. It has a takeoff weight of about 849 tonnes and a payload capacity of 22 tonnes to low-Earth orbit, said Wang Jue, chief director of the Long March-5 development team at the China Academy of Launch Vehicle Technology under the China Aerospace Science and Technology Corporation.
After the maiden flight of the Long March-5B, the Long March-5 carrier rocket will launch China's first Mars probe and the Chang'e-5 lunar probe later this year.
China aims to complete construction of the space station around 2022. According to the CMSA, more than 10 missions are planned in the next three years to complete the construction and master technologies for in-orbit assembly and construction of large complex spacecraft, long-term manned spaceflight in near-Earth space and large-scale space science experiments.
China still faces many challenges, so joint drills at the space launch center and the maiden flight of the Long March-5B are very important, said experts.
The space station will be a T shape with the Tianhe core module at the center and a lab capsule on each side. The core module -- at 16.6 meters long and 4.2 meters in diameter, with a takeoff weight of 22.5 tonnes -- will be the management and control center.
China's current largest spacecraft, the Tianhe core module will be able to support a long-term stay of three astronauts in space.
The living space in the core module is about 50 cubic meters. With the two lab capsules, the living space could be up to 110 cubic meters, which would provide the astronauts a confortable environment, said experts from the China Academy of Space Technology (CAST), the main developer of the space station capsules.
The longest stay in space so far by Chinese astronauts is 33 days. The necessary water and oxygen were taken into space. To enable astronauts to stay longer in orbit, the space station will be equipped with a renewable life support system, said experts.
The water vapor exhaled by astronauts will be recovered by condensation, and urine will be recycled and purified as drinking water and domestic water. The hydrogen produced in electrolytic oxygen production and the carbon dioxide exhaled by astronauts can generate oxygen through chemical reaction, which can supplement oxygen for the space station.
Science facilities on the space station could support hundreds of research projects in fields such as astronomy, space life science, biotechnology, microgravity, basic physics and space materials.
More than a dozen advanced experiment racks will be installed, and an extra-vehicular experiment platform will be built. In addition, a capsule holding a large optical telescope will fly in the same orbit.

The rocket, the prototype core capsule of the space station and the experimental manned spaceship are undergoing tests at the Wenchang Space Launch Center on the coast of south China's island province of Hainan.
During the flight in mid to late April, the experimental manned spaceship will be sent into space with no crew. The prototype of the core capsule of the space station will not be launched.
The Long March-5B is a modified version of the Long March-5, currently China's largest carrier rocket, and will be mainly used for sending capsules of China's space station and large spacecraft to the low-Earth orbit, according to the China Manned Space Agency (CMSA).
Space engineers developed a new large fairing, which is 20.5 meters long and 5.2 meters in diameter, for the Long March-5B. The whole rocket is about 53.7 meters long, with a 5-meter diameter core stage and four 3.35-meter diameter boosters.
The rocket uses environment-friendly fuel, including kerosene, liquid hydrogen and liquid oxygen. It has a takeoff weight of about 849 tonnes and a payload capacity of 22 tonnes to low-Earth orbit, said Wang Jue, chief director of the Long March-5 development team at the China Academy of Launch Vehicle Technology under the China Aerospace Science and Technology Corporation.
After the maiden flight of the Long March-5B, the Long March-5 carrier rocket will launch China's first Mars probe and the Chang'e-5 lunar probe later this year.
China aims to complete construction of the space station around 2022. According to the CMSA, more than 10 missions are planned in the next three years to complete the construction and master technologies for in-orbit assembly and construction of large complex spacecraft, long-term manned spaceflight in near-Earth space and large-scale space science experiments.
China still faces many challenges, so joint drills at the space launch center and the maiden flight of the Long March-5B are very important, said experts.
The space station will be a T shape with the Tianhe core module at the center and a lab capsule on each side. The core module -- at 16.6 meters long and 4.2 meters in diameter, with a takeoff weight of 22.5 tonnes -- will be the management and control center.
China's current largest spacecraft, the Tianhe core module will be able to support a long-term stay of three astronauts in space.
The living space in the core module is about 50 cubic meters. With the two lab capsules, the living space could be up to 110 cubic meters, which would provide the astronauts a confortable environment, said experts from the China Academy of Space Technology (CAST), the main developer of the space station capsules.
The longest stay in space so far by Chinese astronauts is 33 days. The necessary water and oxygen were taken into space. To enable astronauts to stay longer in orbit, the space station will be equipped with a renewable life support system, said experts.
The water vapor exhaled by astronauts will be recovered by condensation, and urine will be recycled and purified as drinking water and domestic water. The hydrogen produced in electrolytic oxygen production and the carbon dioxide exhaled by astronauts can generate oxygen through chemical reaction, which can supplement oxygen for the space station.
Science facilities on the space station could support hundreds of research projects in fields such as astronomy, space life science, biotechnology, microgravity, basic physics and space materials.
More than a dozen advanced experiment racks will be installed, and an extra-vehicular experiment platform will be built. In addition, a capsule holding a large optical telescope will fly in the same orbit.

Long March-2D conducts maiden launch from Xichang with four satellites
written by Rui C. Barbosa February 19, 2020
Taking precautions with the coronavirus outbreak in all orbital and space launch centers, China returned to its launch activities after the Chinese New Year festivities with a new launch from the Xichang Satellite Launch Center.
This was the first use of a Long March-2D (Chang Zheng-2D) launch vehicle from Xichang. The mission orbited four satellites that will be used to carry out inter-satellite link networking and new ground observation technology tests in orbit. The launch took place from the LC3 Launch Complex at 21:07UTC.
Named Xinjishu Shiyan-C to F, XJS-C and D were made by SAST, XJS-E by the Harbin Inst of Tech. and XJS-F by CAST’s DFH Satellite Co., Ltd. (DFHSat).
The Long March-2D launch vehicle is a two-stage rocket developed by the Shanghai Academy of Spaceflight Technology. With storable propellants, it is mainly used to launch a variety of low earth orbit satellites.
The development of LM-2D was started in February 1990. From 2002, to meet the demand of SSO satellites, the payload fairing of 3350mm in diameter and attitude control engine for the second stage have been successfully developed; and the discharge of remaining propellant and de-orbit of the second stage have been realized. This launcher is mainly used for launching LEO and SSO satellites. It is characterized by high reliability, wide application and mature technology.
The LM-2D can launch a 1,300 kg cargo in a 645 km SSO. The rocket is 41.056m long and the first, second stages and payload fairing are all 3.35m in diameter.
Its first stage is the same as the Long March-4. The second stage is based on LM-4 second stage with an improved equipment bay. Lift-off mass is 232,250 kg, total length 41,056 meters, diameter 3.35 meters and fairing length 6.983 meters. At launch, it develops 2961.6kN engine thrust.
The first stage has a 27.910 meter length with a 3.35 meter diameter, consuming 183,200 kg of N2O4 / UDMH (launch mass of the first stage is 192,700 kg). Equipped with a YF-21C engine capable of a ground thrust of 2,961.6 kN and a ground specific impulse of 2,550 m/s. Burn time is 170 seconds.
The second stage has a 10.9 meter length with a 3.35 meter diameter, a launch mass of 39,550 kg and consuming 45,550 kg of N2O4 / UDMH. Equipped with a YF-24C cluster engine with a main engine vacuum thrust of 742.04 kN and a vernier engine with a vacuum thrust of 47.1 kN (specific impulses of 2,942 m/s and 2,834 m/s, respectively).
The LM-2D can use two types of fairings depending on the cargo. Type A fairing has a 2.90 meters diameter (total launch vehicle length is 37.728 meters) and Type B fairing with a diameter of 3.35 meters – total launch vehicle length is 41.056 meters.
The first launch of the LM-2D was on August 9th, 1992 from the Jiuquan Satellite Launch Center orbiting the Fanhui Shei Weixing FSW-2-1 (22072 1992-051A) recoverable satellite.
The launch took place from the Xichang Satellite Launch Centre that is situated in the Sichuan Province, south-western China and is the country’s launch site for geosynchronous orbital launches.
Equipped with two launch pads (LC2 and LC3), the center has a dedicated railway and highway lead directly to the launch site.
The Command and Control Centre is located seven kilometers south-west of the launch pad, providing flight and safety control during launch rehearsal and launch.
Other facilities on the Xichang Satellite Launch Centre are the Launch Control Centre, propellant fuelling systems, communications systems for launch command, telephone and data communications for users, and support equipment for meteorological monitoring and forecasting.
The first launch from Xichang took place at 12:25UTC on January 29, 1984, when the Chang Zheng-3 (Y-1) was launched the Shiyan Weixing (14670 1984-008A) communications satellite into orbit.

New binary millisecond pulsar discovered in NGC 6205
by Tomasz Nowakowski , Phys.org
Positions of the six pulsars in the GC M13, marked with red circles with letters. Credit: Wang et al., 2020.
Using the Five-hundred-meter Aperture Spherical radio Telescope (FAST), astronomers have detected a new binary millisecond pulsar (MSP) in the globular cluster NGC 6205. The newly found pulsar received designation PSR J1641+3627F. The finding is reported in a paper published February 14 on the arXiv pre-print repository.
Pulsars are highly magnetized, rotating neutron stars emitting a beam of electromagnetic radiation. The most rapidly rotating pulsars, with rotation periods below 30 milliseconds, are known as millisecond pulsars (MSPs).
Astronomers believe that MSPs form in binary systems when the initially more massive component turns into a neutron star that is then spun-up due to accretion of matter from the secondary star. Observations conducted so far seem to support this theory, as more than a half of known MSPs have been found to have stellar companions.
Now, a team of astronomers led by Lin Wang of CAS (Chinese Academy of Sciences) Key Laboratory of FAST in China, reports the detection of a new MSP in the bright globular cluster NGC 6205 (also known as M13), which is located some 23,150 light years away in the constellation of Hercules. The discovery was made as part of FAST observations of NGC 6205 that also monitored other pulsars in this cluster.
"In this paper, we present the discovery of the binary pulsar PSR J1641+3627F (M13F) and timing solutions of all the known pulsars in the GC M13," the astronomers wrote in the paper.
According to the study, PSR J1641+3627F has a spin period of approximately 3.0 milliseconds and an orbital period of 1.38 days. This means that it has the second shortest spin period and the longest orbital period among the six pulsars that have been discovered in NGC 6205 (the other five are designated PSR J1641+3627A to E).
FAST observations show that PSR J1641+3627F has a dispersion measure of around 30.4 parsecs/cm3. It was noted that this is close to the average dispersion measure value of other known pulsars in NGC 6205. The mass of the companion object is estimated to be around 0.16 solar masses, what suggests a white dwarf.
The research also found that PSR J1641+3627F is located at the edge of the cluster core and its spin period derivative is typical for MSPs in globular clusters. However, the system's eccentricity is, according to the astronomers, relatively small when compared to typical MSP-white dwarf systems.
In general, the researchers concluded that all the discovered binary systems in NGC 6205 have relatively low eccentricities when compared to typical globular cluster pulsars and the eccentricities were found to decrease with distance from the cluster core.
"This is consistent with what is expected as this cluster has a very low encounter rate per binary," the authors of the paper underlined.

China's Yuanwang-7 sailing to Atlantic for satellite monitoring mission
Source: Xinhua| 2020-02-28 14:05:30|Editor: huaxia
NANJING, Feb. 28 (Xinhua) -- China's new-generation space tracking ship Yuanwang-7 is sailing to the Atlantic Ocean for a satellite maritime monitoring mission.
The ship departed from a port of the China Satellite Maritime Tracking and Controlling Department in Jiangsu Province Thursday. It is the first time for Yuanwang-7 to carry out a mission in the Atlantic.
Only one ship of China's Yuanwang fleet, Yuanwang-3, so far has conducted missions in the ocean.
"This time the designated maritime area is remote and the route is new. We estimate that the vessel will sail in waves higher than 4 meters for over 10 days, a tougher journey than before," said Ni Liuguo, captain of the ship.
Before setting out, crew members were quarantined on the vessel and cabins were disinfected to prevent the novel coronavirus infection. They completed the preparation of medical supplies and examined facilities to ensure the success of the mission.
Yuanwang-7 was developed with the latest technologies in shipbuilding, space measurement and control, marine meteorology and shipping power.
Since it was put into use in 2016, Yuanwang-7 has made 13 voyages and performed 21 tasks in the Pacific Ocean and the Indian Ocean, including maritime tracking of China's second space lab Tiangong-2, the Chang'e-4 lunar probe and BeiDou satellites.
China will have more than 40 space launches this year, and the Yuanwang fleet is expected to carry out intensive maritime monitoring missions.
