ЦитироватьIn June, the Shijian 18 communications satellite, the first developed based on China's new-generation DFH 5 satellite platform, will be lifted by a Long March 5 rocket at the Wenchang Space Launch Center in Hainan province, according to the academy.

It said the transmission capacity of the satellite to be launched in June is double that of current Chinese communications satellites, allowing more television channels and clearer programs to be transmitted. The new satellite will also improve internet connectivity and accessibility as well as reduce users' costs.

ЦитироватьShijian-18 meanwhile will be the first test of a new satellite bus, DFH-5, with a mass of up to 7 tonnes that requires the heavy-lift Long March 5 to take it to nearly 36,000 km above the Earth.
 
The June mission will be the second for the new carrier rocket, with China hoping for a less dramatic launch than its ultimately successful debut in November.

China's second Long March 5 heavy-lift launch vehicle left port in Tianjin on Monday and is now heading to the Wenchang launch site on Hainan Island in preparation for launch of an experimental communications satellite in June.

The Long March 5 Y2 components are being transported by the Yuanwang-21 and 22 cargo ships which were specially designed for delivering China's new generation of large launch vehicles from North China to the Wenchang Satellite Launch Centre.

After assembly and testing, the Long March 5 Y2 will in June launch the experimental Shijian-18 satellite, which uses the country's newest and heaviest satellite platform, DFH-5.

The DFH-5 was developed by the China Academy of Space Technology (CAST) and has a mass of up to 8,000 kg with a payload of 1500 kg, requiring the heavy-lift Long March 5 to take it to nearly 36,000 km above the Earth.

It will also test newly developed LIPS-300 ion thrusters, which are more powerful versions of the LIPS-200 engines used on the recently launched Shijian-13 (http://gbtimes.com/china/china-launches-experimental-shijian-13-satellite-long-march-3b-xichang) satellite and marked a first full use of electric propulsion for China.

Shijian-13  (http://gbtimes.com/china/china-launches-experimental-shijian-13-satellite-long-march-3b-xichang)(Shijian means 'practice') is China's first high throughput satellite, marking a big boost to the country's telecommunication satellite transmission volume.

Shijian-13 is capable of providing 100 Mbit wireless internet service simultaneously to 300,000 users, according to the State Administration of Science, Technology and Industry for National Defence (SASTIND). Shijian-18 is rumoured to exceed these capabilities.

At over 50m high and with a diameter of 5m, the Long March 5 will have a mass at liftoff of around 800 metric tonnes, with the heaviest lift configuration capable of putting a 25 tonne payload into low Earth orbit or 14t to geostationary transfer orbit, greatly boosting China's space capabilities.

Background: Five things to know about China's Long March 5 rocket (http://gbtimes.com/china/five-things-know-about-chinas-long-march-5-rocket)

China is preparing for the launch of one of the heaviest ever satellites to geostationary orbit next month, with the country's second Long March 5 heavy-lift launch vehicle being assembled at the Wenchang Satellite Launch Centre.

Shijian-18 is an experimental telecommunications satellite which, at around seven metric tonnes or more launch mass, will possibly be the most massive satellite launched to geostationary orbit, nearly 36,000 km above the Earth.

It will be the first deployment of the new Dongfanghong-5 (DFH-5) satellite platform, the country's most advanced and heaviest, which requires the new Long March 5 to send it into geosynchronous transfer orbit.

Shijian-13 (http://gbtimes.com/china/china-launches-experimental-shijian-13-satellite-long-march-3b-xichang), launched last month, was China's first high-throughput satellite with a capacity of more than 20 Gbps, and marked the country's first full use of electric propulsion with LIPS-200 engines, developed by the Lanzhou Institute of Physics.

Shijian-18 will immediately overshadow those capabilities, boasting a capacity of around 70 Gbps, while also feature more powerful LIPS-300 ion thrusters.

Long March 5 payload

Shijian-18 is based on the China's new, untested Dongfanghong-5 (DFH-5) satellite platform. At around seven metric tonnes, it will be one of the most massive satellites sent to geostationary orbit, some 36,000 kilometres above the Earth.

The High-Throughput satellite will boast a capacity of around 70 Gbps, and test both space-based laser communications and powerful LIPS-300 ion thrusters, which will be used for station keeping.

At over 53m high and with a core diameter of 5m, the Long March 5 will have a mass at liftoff of around 800 metric tonnes.

Though its development was delayed by technical challenges, the launch vehicle greatly boosted China's space capabilities.

Fuelled by crogenic liquid hydrogen, kerosene and liquid oxygen, the Long March 5 family can loft a payload of 25 tonnes to low Earth orbit, 14 tonnes in geostationary transfer orbit, boosting China's launch capabilities by 2.5 times over pre-existing Long March carrier rockets.

Background: Five things to know about China's Long March 5 (http://gbtimes.com/china/five-things-know-about-chinas-long-march-5-rocket)

It will also launch China's first independent interplanetary mission, to Mars (http://gbtimes.com/china/china-unveils-its-mars-2020-probe-and-science-goals), in 2020. A variant for low Earth orbit launches, the Long March 5B, will be used to launch 20 metric tonne modules for the future Chinese Space Station (http://gbtimes.com/china/chinas-space-station-2-arms-wings-and-chinese-hubble).

The core module, Tianhe (http://gbtimes.com/china/china-has-completed-its-space-station-core-module-ready-launch-2018), is ready for launch in 2019, following a test launch of the 5B next year, which could carry a test return capsule for a next-generation Chinese crewed spacecraft.

The Long March 5, developed by the China Academy of Launch Vehicle Technology (CALT) , is comparable to the most powerful active rockets in the world such as the Delta-IV Heavy (http://www.spaceflight101.com/delta-iv-heavy.html), Atlas V and Ariane 5 (http://www.arianespace.com/vehicle/ariane-5/).

The new launch vehicle also meant new facilities. While China's established Long March 2, 3, and 4 can transported by train to the three inland launch sites at Jiuquan and Taiyuan in the north and Xichang in the southwest, the five-metre diameter core of the Long March 5 makes it too wide for the transport infrastructure.

Video: China opens up over dramatic Long March 5 launch (http://gbtimes.com/china/china-opens-over-dramatic-long-march-5-launch)

So a new coastal launch centre was required and established on the southern island province of Hainan. Being closer to the equator, the Wenchang launch site also gives rockets a boost from the greater rotational speed of the Earth.

Two specially designed ships, Yuanwang 21 and 22, deliver components for the Long March 5 and 7 from Tianjin to Hainan.

China's Long March 5 – ranking among the most powerful rockets in the world – is standing ready atop its launch pad on Hainan Island for liftoff this weekend with one of the heaviest, if not the heaviest Geostationary Satellite ever flown, test driving a new platform that enables future ultra-high performance satellites.

Спойлер

Long March 5 is the most powerful member of China's new line of rockets that debuted in the last two years to slowly phase into operational missions as the country aims to replace its antiquated rocket technology relying on lower-efficiency toxic propellants with modern rockets that are environmentally friendly and offer a much greater performance which is badly needed to meet China's ambitious goals in human spaceflight and robotic solar system exploration.

The Long March 5 took flight for the first time (http://spaceflight101.com/cz-5-maiden-flight/) on November 3, 2016 – lighting up the night skies over its picturesque launch site after a dramatic countdown that had engineers and controllers scrambling to work around a series of issues that cropped up as late as T-2 minutes.

Long March 5 Maiden Launch – Photo: Xinhua

Rising fr om its pad, Long March 5 provided quite a sight as it streaked into the night under the power of its four large boosters and cryogenic core stage. The mission was not without trouble and suffered a premature shutdown of the rocket's second stage, requiring the YZ-2 upper stage to use performance margin planned for the inaugural flight to compensate and inject the Shijian-17 satellite into the planned Geostationary Drift Orbit.

Engineers are hoping all teething issues were ironed out and Long March 5 will be able to demonstrate its reliability on Sunday's flight in order to clear the heavy-lifter for its upcoming high-profile mission in November, lifting the Chang'e 5 (http://spaceflight101.com/change/change-5/) lunar sample return mission.

Long March 5 will also be called upon for the launch of China's first Mars Global Remote Sensing Orbiter and Rover Mission in 2020 and it will lift the Tianhe Core Module and two science laboratory modules for the Chinese Space Station starting in 2019.

Sunday's launch appears to be targeting liftoff around 11:20 UTC, 7:20 p.m. local time based on navigational warnings, however, as shown by the last mission, Long March 5 can have an extended launch window if the satellite's specifications allow.

Hidden under the rocket's payload fairing is Shijian-18, an experimental communications satellite that is debuting the DFH-5 next-generation satellite bus developed by the Chinese Academy of Space Technology (CAST) for future ultra-high performance communications satellites.

>>Shijian-18 Satellite & DFH-5 Satellite Platform (http://spaceflight101.com/long-march-5-shijian-18/shijian-18/)

(https://img.novosti-kosmonavtiki.ru/153246.png) (http://spaceflight101.com/long-march-5-shijian-18/wp-content/uploads/sites/167/2017/06/211629h3mr4l02j3k3l4z3.png)

With a reported launch mass of seven metric tons, Shijian-18 appears to be the heaviest unclassified Geostationary Satellite launched to date, surpassing the TerreStar-1 satellite that is the current record-holder with a launch mass of 6,902kg.

The DFH-5 satellite platform builds upon new satellite technology developed for the current-generation DFH-4 platform and adds a number of innovative developments such as a truss structure building the backbone of the large satellite, new 2D Twice Deploying Semi-Rigid Solar Arrays, advanced thermal control systems with deployable radiators, and a new type of self-controlled propellant system.

DFH-5 uses hybrid propulsion with chemical thrusters and new high-thrust ion propulsion for stationkeeping over extended mission lives.

According to CAST, DFH-5 more than triples the payload capacity of current satellites and future iterations of the vehicle may weigh up to 9,000 Kilograms and support payloads of up to 2,200 Kilograms with a payload power of up to 28 Kilowatts – surpassing any satellite bus currently in operation.

DFH-5 Satellite – Image: CAST

Shijian-18 is outfitted with a powerful High-Throughput Payload operating in Ka-Band and delivering a number of high-capacity beams. China launched its first high-throughput satellite earlier this year (Shijian-13 (http://spaceflight101.com/long-march-3b-launches-shijian-13/)) with a total data throughput of 20Gbps, to be eclipsed by Shijian-18 that will deliver a throughput in excess of 70 Gbps.

CAST says the DFH-5 satellite platform will be suitable for China's highest capacity communications satellites and the bus will also be available to international customers looking for high-power applications. Other potential uses of DFH-5 are in Earth Remote Sensing and some technologies developed for the program, such as the LIPS-300 ion thrusters, could be adapted for Solar System missions like asteroid explorers.

This weekend's mission with Shijian-18 will significantly reduce margins for Long March 5 versus the launch of the ~4-metric ton Shijian-17 last year, not allowing for performance shortfalls on any stage of the flight. The three-stage version of Long March 5 can lift 14 metric tons into a standard Geostationary Transfer Orbit and around 4,500 Kilograms directly to Geostationary Orbit; Shijian-18 is likely aiming for a GTO with reduced delta-v to GEO (either through a supersynchronous injection or a multi-hour ascent with perigee-raising maneuver).

If launching at the expected time on Sunday, Long March 5 will take flight just seven minutes after sunset, making for a potentially spectacular scene as the vehicle rises into illumination before flying toward night. Overall, Long March 5 stands 57 meters tall and weighs 867 metric tons at liftoff – employing two five-meter diameter cryogenic rocket stages, four Kerolox boosters and a hypergolic-fueled YZ-2 upper stage capable of multiple engine re-starts.

Ignition sequence start will be commanded at T-10 seconds, with the twin YF-77 engines on the core stage firing up first to reach operational conditions before the boosters command their YF-100 engines to ignite and lift the rocket off the ground with a total thrust of 1,078 metric-ton-force.

Clearing its 92-meter tall Service Tower, Long March will pitch and roll onto a south-easterly departure path to head towards the equator as part of a standard Geotransfer mission design.

The four boosters, each with its own YF-100 engine that builds a common element of China's new rocket series, will fire until T+173 seconds, each burning around 135 metric tons of Liquid Oxygen and Kerosene to deliver 240 metric-ton-force of thrust. Separation of the 27-meter long, 3.35m diameter boosters will occur over 70 Kilometers in altitude via separation motors.

Heading on towards orbit, Long March 5 will rely on its two YF-77 cryogenic main engines for another five minutes, delivering 143 metric-ton-force of thrust when flying through the rarefied upper atmosphere. YF-77 is China's first high-thrust full cryogenic engine, marking a significant technological development. Employing an open staged combustion cycle, YF-77 was built to be efficient at sea level and in the tenuous upper atmosphere to be suitable for a long-burning core stage.

Booster Separation – Photo: CCTV

Separation of the 12.5-meter long fairing halves is expected a little over four and a half minutes into the flight when Long March 5 will be well over 120 Kilometers in altitude where aerodynamic forces are no longer a concern to the satellite. The core stage will finish its job just shy of T+8 minutes, having burned through some 160 metric tons of Liquid Oxygen and Liquid Hydrogen to accelerate the stack to ~5.8 Kilometers per second. Separation of the 33-meter tall core will follow within seconds of shutdown to clear the rocket's second stage for ignition.

Stage 2 is powered by a pair of YF-75D engines, each delivering nine metric-ton-force of thrust, employing an expander cycle in which the Hydrogen propellant is expanded into is gaseous phase to drive the turbopumps. The engines are highly throttle-able and can be ignited multiple times to allow Long March 5 to support flexible mission profiles.

(https://img.novosti-kosmonavtiki.ru/153238.jpg) (http://spaceflight101.com/long-march-5-shijian-18/wp-content/uploads/2017/06/CZ-5-Maiden-Launch-141.jpg)
Second Stage Engine Section – Photo: CCTV

A standard Geotransfer mission comprises a pair of firings of the second stage, the first a little over six minutes in duration to raise the vehicle's speed by two Kilometers per second and reach a Low Earth Parking Orbit around 170 Kilometers in altitude. Concluding its first burn, the second stage will coast for eleven minutes to move to a position close to the equator for the second burn, aiming to place the vehicle into a sub-GTO type orbit from wh ere the Yuanzheng-2 upper stage will take over powered flight duties.

Depending on the mission profile chosen for the Shijian-18 mission, Yuanzheng-2 is likely looking at a pair of engine burns, the first immediately after separation from the second stage, firing up its twin 660kgf YF-50D engines to boost the stack into an elliptical transfer orbit with apogee near GEO altitude. The second burn would then occur after a lengthy climb to apogee in order to reduce the inclination and raise the perigee, cutting the fuel expenditure by the satellite for its climb into a stationary orbit. Should this profile be chosen, separation of the satellite would be expected nearly six hours after liftoff.

ЦитироватьSecond launch of China's Long March 5 heavy-lift rocket set for Sunday
July 1, 2017 (https://spaceflightnow.com/2017/07/) Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

China's Long March 5 rocket is counting down to liftoff Sunday from the country's tropical island space center with a high-power, electrically-propelled communications satellite.

The heavy-lifter is scheduled to blast off from the Wenchang launch base on Hainan Island at around 1120 GMT (7:20 a.m. EDT; 7:20 p.m. Beijing time) Sunday, heading for an elliptical geostationary transfer orbit with the Shijian 18 communications satellite, the first in a new series of modern Chinese high-capacity relay stations.

Sunday's launch will be the second flight of a Long March 5 rocket, China's most powerful launcher, which made a successful maiden mission in November 2016.

Chinese space officials will closely watch the performance of the Long March 5 rocket Sunday as engineers prepare to send China's Chang'e 5 sample return mission to the moon in November on the third launch of the heavy-lifter.

Спойлер

Ten engines on the Long March 5's first stage and four strap-on boosters will send the launcher skyward on 2.4 million pounds of thrust. The 187-foot-tall (57-meter) Long March 5 will head east from the Hainan Island launch base, which will host its fourth launch Sunday after entering service last year.

Ground crews at Wenchang rolled the Long March 5 to its launch pad Monday.

Riding on a vertical launch table, the Long March 5 completed the trip in about two-and-a-half hours, according to the China Academy of Launch Vehicle Technology. Swing arms on the seaside launch pad's 300-foot-tall (92-meter) service gantry enclosed the Long March 5 for final launch preparations.

China's state-run media has not said if they plan any live coverage of the launch.

The Long March 5's maiden test flight last year deployed an experimental satellite named Shijian 17 to test electric thrusters, technology that could give Chinese spacecraft improved maneuverability between different types of orbits around Earth.

The Shijian 18 satellite aboard Sunday's flight is the first in an upgraded series of Chinese spacecraft called the DFH-5 platform. Developed by the China Academy of Space Technology, the DFH-5 design is bigger and more capable than China's existing satellites, providing more power for communications payloads and additional data throughput for Internet providers, television broadcasters and data networks.

Shijian 18 also hosts a laser communications instrument for even higher-speed data links, and ion thrusters will keep the spacecraft in geostationary orbit, a perch more than 22,000 miles (nearly 36,000 kilometers) over the equator.

China hopes to sell communications satellites based on the new DFH-5 design to international governments and commercial customers.

Ground controllers will run the Shijian 18 satellite through extensive testing to verify the new satellite design works as expected.

Chinese officials say the Long March 5 is a centerpiece of the country's long-term space ambitions, allowing China to dispatch satellites to space that are twice as heavy as payloads that can fit on earlier Long March rockets.

The heavy-duty rocket can haul about the same amount of weight into space as United Launch Alliance's Delta 4-Heavy, the world's other leader in space lift capability. The Long March 5 bests the capacity of the European Ariane 5 and Russian Proton launchers.

The Long March 5 is one of three new launch vehicles China has debuted in the last two years.

The Long March 6 is the smallest of the three, tailored to deliver small satellites into low-altitude orbits.
 
The medium-lift Long March 7 is designed to carry resupply ships, and eventually crews, to China's future space station.

The Long March 5 will haul three 20-ton modules to low Earth orbit for the Chinese space station, beginning next year with the launch of the Tianhe 1 core module. The Long March 5 is also slated to launch the robotic Chang'e 5 mission to the moon later this year to scoop up surface samples for return to Earth, and China's first Mars rover will ride a Long March 5 rocket when it blasts off in mid-2020.

The new family of launchers will eventually replace China's Long March 2, 3 and 4 rockets, which burn toxic liquid propellants and launch from inland space centers, requiring them to drop spent stages on land.

The Long March 5 rocket, when flown from Wenchang, jettisons its boosters over the South China Sea. Its engines also consume a more environmentally-friendly mixture of liquid oxygen, liquid hydrogen and kerosene.

ЦитироватьКОСМОДРОМ ВЭНЬЧАН (Китай), 2 июл – РИА Новости, Анна Раткогло. Китайская ракета-носитель тяжёлого класса "Чанчжэн-5" ("Великий поход-5") со спутником "Шицзянь-18" в воскресенье стартовала с космодрома Вэньчан в провинции Хайнань, передает корреспондент РИА Новости.

Старт ракеты состоялся в воскресенье в 19.23 по местному времени (14.23 мск). Это второй пуск для ракет-носителей серии "Чанчжэн-5" и 250 для ракет-носителей "Великий поход" в целом.

Спойлер

В середине апреля Китай произвел успешный пуск первого из шести телекоммуникационных спутников серии "Шицзянь" для обеспечения скоростного беспроводного интернета в транспорте. Тогда с космодрома Сичан в провинции Сычуань с помощью ракеты-носителя "Чанчжэн-3B" был запущен спутник "Шицзянь-13".

В середине февраля сообщалось, что Китай планирует в 2017 году осуществить запуск шести телекоммуникационных спутников для обеспечения скоростного беспроводного интернета в транспорте, в частности в самолетах и высокоскоростных поездах.

"Чанчжэн-5" — самая мощная ракета-носитель нового поколения Китая. Ее высота составляет 56,97 метра, диаметр основной ступени — пять метров. Она способна вывести на низкую околоземную орбиту 25 тонн груза. Проект по разработке "Чанчжэн-5" был утвержден Госсоветом КНР в 2006 году. В качестве топлива для "Чанчжэн-5" используется жидкий кислород и жидкий водород.

ЦитироватьChina's Long March 5 Fails on Second Orbital Mission, innovative Shijian-18 Satellite lost
 July 2, 2017 (http://spaceflight101.com/long-march-5-shijian-18/chinese-long-march-5-fails-on-second-mission/)

China's most powerful rocket suffered a major setback on Sunday when it failed to send the Shijian-18 experimental communications satellite into orbit to test drive a new ultra-high-performance satellite platform.

China's official Xinhua news agency confirmed the mission ended in failure and said an investigation was being convened, though details on the circumstances of the mishap are not yet clear.

Conducting its second launch, Long March 5 lifted off fr om a picturesque tropical launch site on Hainan Island at sunset on Sunday, rising into sunlight shortly after blastoff before disappearing in the night on its second orbital mission.

The 57-meter tall Long March 5 lifted off fr om Launch Complex 101 at the Wenchang Satellite Launch Center at 11:23 UTC, 7:23 p.m. local time – rising under the power of twin cryogenic engines and four Kerosene-fueled rocket boosters to begin a half-hour climb into a high-energy orbit.

All appeared to go by the book in the initial ascent phase until trouble struck some time after the rocket shed its four boosters. Separation of the core stage from the also-cryogenic second stage was around 100 seconds later than planned and the second stage's burn did not match pre-flight prediction as the vehicle appeared to lose altitude.

It is not clear what lies at the root cause of the in-flight anomaly.

Sunday's mission came after the debut launch of Long March 5 last November that saw the successful delivery  (http://spaceflight101.com/cz-5-maiden-flight)of the Shijian-17 satellite directly to Geostationary Orbit in a mission surrounded by much more excitement than engineers had bargained for. Throughout the countdown and as late as T-2 minutes, engineers were scrambling to work around a string of problems from issues related to fueling to telemetry drop outs. The rocket's inaugural mission was also not free from trouble as the second stage shut down around 11 seconds early, requiring the upper stage to make up for lost performance using generous margin built into the debut mission.

Engineers hoped they had ironed out all teething issues for Sunday's mission that had the primary goal of validating Long March 5's reliability to clear the heavy-lifter for high-profile missions starting with the launch of the Chang'e 5 (http://spaceflight101.com/change/change-5/) lunar sample return mission in November. China will also rely on the Long March 5 for the launch of the Tianhe Core Module in 2019 as well as the two major science modules of the Chinese Space Station early in the next decade.

Long March 5 Configuration – Image: CALT

Long March 5 represents a cornerstone in China's space ambitions and will be called upon for a variety of missions ranging from heavy hauls into Low Earth Orbit with Space Station components, launching the country's heaviest geostationary satellites, to supporting solar system exploration by launching interplanetary probes such as China's 2020 Mars rover.

Utilizing modern rocket technology like Kerolox and full cryogenic stages, Long March 5 closely matches or even surpasses the performance of current industry workhorses like the European Ariane 5, Russia's Proton and the Delta IV Heavy, which still holds the rank as the most powerful launcher on the American market until SpaceX can introduce its Falcon Heavy which has about twice the performance of the CZ-5 (when flying expendable).

Long March 5 is the largest member in China's new line of rockets that was introduced in the last two years to mark a major shift in rocket technology, stepping away from the hypergolic propellants used by the Chinese for more than four decades and introducing Kerolox and cryogenic propulsion systems that offer a much better performance at a fraction of the cost plus are more environmentally friendly.

Following its first flight in 2016, Long March 5 was expected to keep an initial pace of around two flights per year and preparations for the Y2 mission began back in late April when the Long March 5 was delivered via ship from its manufacturing plant in Tianjin. The fully assembled rocket with Shijian-18 under its payload fairing was moved to the LC-101 launch pad on June 26 for several days of checkouts prior to heading into countdown operations.

Long March 5 comprises two cryogenic rocket stages powered by Liquid Oxygen and Liquid Hydrogen, four Kerolox boosters for the initial kick toward orbit and an optional hypergolic-fueled YZ-2 upper stage that was not in use on Sunday and comes into play for Medium-Earth and direct-to-GEO missions. The vehicle weighs 867 metric tons at liftoff and spans 12 meters from side to side.

The Long March 5 rocket entered propellant loading at 8:30 UTC on Saturday, beginning with filling the four boosters with 150 metric tons of Kerosene stored at room temperature. Loading of cryogenic Liquid Oxygen into the boosters and the two stages as well as LH2 load on the core stages picked up on Sunday with no issues reported as the vehicle received some 580 metric tons of cryogenics. The protective Service Platforms opened up an retracted from the vehicle in the last four hours to launch and all tanks entered a stable replenish well ahead of liftoff.

Ignition sequence start was commanded at T-10 seconds and red flames erupted from the base of the rocket at T-6.8 seconds when the twin hydrogen-fueled YF-77 engines on the Core Stage were commanded to ignite followed at T-3 seconds by the eight YF-100 engines on the boosters – catapulting Long March 5 off the pad when clocks reached zero.

Long March 5 took flight at precisely 11:23:23.425 UTC, rising from its launch pad on Hainan Island in a vertical posture before pitching over onto a departure to the east-south-east to head towards the equator. Many spectators at China's only publicly accessible spaceport watched in awe as Long March 5 thundered into twilit skies with a total thrust of 1,078 metric-ton-force, the boosters doing most of the work in the early flight phase, pushing the vehicle beyond the speed of sound just after hitting the T+1 minute mark.

The boosters fired until T+174 seconds, each generating 240 metric-ton-force of thrust to help accelerate the rocket to a speed of 2.8 Kilometers per second. Each used two YF-100s, an oxygen-rich staged combustion engine that builds the common element in China's new line of rockets, also featured on the Long March 6 and 7, going back to Russia's pioneering oxygen-rich closed cycle engine technology that China acquired in the 1990s.

Booster Separation – Photo: CCTV

Shutting down their engines after each consumed some 135 metric tons of Kerosene and Liquid Oxygen, the 27-meter long boosters separated from the still-firing core stage via pyrotechnics and separation rockets that propelled the boosters outward and away from the core which continued onward using its two YF-77 engines, generating a vacuum thrust of 143 metric ton force.

Wh ere trouble emerged in Sunday's flight is not entirely clear, however, a number of abnormalities became apparent from the live coverage provided of the mission.

Payload fairing separation occurred at the expected time, four minutes and 45 seconds into the flight and was met with applause by mission controllers – indicating there was no sign of any serious anomaly at that point in the launch.

First Sign of Trouble? A white Plume appears on the base of the Core Stage – Photo: CCTV

Five minutes and 47 seconds into the flight, what until then was a well organized jet from the base of the rocket (likely the gas generator exhaust from the open cycle YF-77 engines) suddenly turned into a white cloud bursting away from the lower section of the core stage, indicating some type of breach in a pressurized system. The event appeared to be associated with a disturbance of the rocket's attitude as evident by the sunlit horizon that moved rather rapidly. The venting cloud of gas was still present at T+440 seconds, per video from on board the rocket.

The two YF-77 engines of the core stage were expected to fire until 465 seconds into the flight (7 minutes and 45 seconds) to be followed within three seconds by the separation of the stages and the ignition of the two YF-75D expander cycle engines on the second stage. However, stage separation did not occur until 570 seconds into the mission, 105 seconds later than specified.

Telemetry Plot shows the Second Stage losing Altitude – Photo: Xinhua

The second stage fired up at T+575.3 seconds according to telemetry displays at mission control, aiming to place the stack into a Low Earth Parking Orbit. However, as shown by the telemetry displays, the second stage was dropping in altitude – most likely due to insufficient velocity imparted by the first stage. The timing of when the decline in altitude started is a fairly good match with the emergence of the white gas cloud around the core stage.

Second stage shutdown was marked at T+770.3 seconds after a burn of only three minutes and 15 seconds, insufficient to place the stack into an orbit. Another observation at the start of the second stage burn was a large amount of gimbaling on the twin engines, likely to correct a rather significant deviation of the rocket's orientation that built up toward the end of the first stage's operation.

Second Stage Start-up – Photo: CCTV

At this point, pacing got more nervous at Mission Control and fingers were pointing toward monitors as the realization sunk in that the CZ-5 Y2 mission would not be a successful one.

The original plan called for the second stage to fire for four minutes and 48 seconds to put the stack into a Parking Orbit around 170km in altitude followed by ten minutes of coasting and a 5-minute and 59 second burn to put Shijian-18 into a Supersynchronous Transfer Orbit of 200 x 46,000 Kilometers.

Why the second stage shut down prematurely when it clearly had not made orbit is not apparent – a typical scenario wh ere the second stage starts out at a lower velocity than planned would see the stage extend its burn to reach orbit. One possibility could be that the second stage's flight control system sensed there was no chance of reaching an orbit with the deficit on the first stage and thus shut down its engines. Another possibility is that the second stage was already in the process of re-entering when shutting down the engines.

Sunday's mishap was China's second unsuccessful orbital launch attempt in a row following the botched launch of the Zhongxing-9A communications satellite (http://spaceflight101.com/chinas-long-march-3b-zhongxing-9a-failure/) that ended up in a lower-than-planned orbit when its Long March 3B upper stage encountered a serious issue. 2017 was expected to be a record-setting year for Chinese space flight with Chang'e 5 at the forefront, a launch that is now in doubt after two iffy missions for the Long March 5.

DFH-5 Satellite – Image: CAST

The Long March 5 Y2 mission carried the Shijian-18 experimental communications satellite – a milestone development for the Chinese, debuting a new ultra-high-performance satellite platform and featuring innovative systems like high-thrust ion propulsion, laser communications and ultra-secure quantum communications. Based on the DFH-5 satellite platform, Shijian-18 was the heaviest non-classified Geostationary Satellite ever launched, weighing in at just over seven metric tons according to press reports.

The DFH-5 platform builds on China's current-generation DFH-4 but triples its payload capacity, hosting communications packages up to 2,200 Kilograms with a payload power up to a whopping 28 Kilowatts, surpassing the most powerful commercial platforms currently on the market.

DFH-5 inaugurates innovative systems like a truss acting as structural backbone, twice-deploying solar arrays, high-thrust ion engines for orbit control and a new type of self-controlling propellant system.

Shijian-18 hosted a powerful high-throughput communications payload operating in the Ka-Band frequency range and providing a total data throughput of 70 Gbps, eclipsing China's first high-throughput satellite (http://spaceflight101.com/long-march-3b-launches-shijian-13/) that launched earlier this year and has a capacity of 20Gbps.

State-run media also reported Shijian-18 was outfitted with an optical communications payload, taking advantage of the short wavelength of the infrared/visible spectrum to increase the bandwidth over radio communications ten- to one-hundred-fold. The laser terminal installed on Shijian-18 was to reach a downlink data rate of 4.8 Gbit/s, according to the satellite's chief designer, paving the way for future high-data rate communications for application on Earth and over cosmic distances for solar system exploration.

Continuing China's efforts in quantum communications and quantum computing, Shijian-18 was reportedly carrying a Quantum Communications Payload – the first to be tested from Geostationary Orbit over a distance of 36,000 Kilometers.

China has become a trailblazer in the field of quantum communications, launching the Mozi Quantum Science Satellite (http://spaceflight101.com/quantum-science-satellite-declared-operational/) into orbit last year to demonstrate Quantum Key Distribution, the exchange of cryptographic keys between two parties, by means of correlated, or entangled photons – particles of light.

Quantum communications – governed by fascinating physics and offering many promising applications – are inherently secure, any attempt to eavesdrop on a quantum link is impossible. Prior to Mozi, quantum communications were only possible over a distance of a few hundred Kilometers; China planned to attempt to bring quantum communications to Geostationary Orbit with Shijian-18 which would enable a global quantum communications network to be established for full, hacking-proof communications.

The cause of the failure was simply a manufacturing defect in one of the two YF-77 hydrogen-burning engines of the core first stage, says a source close to the Chinese industry.
/.../

ЦитироватьTOKYO — China's Long March rocket series has suffered three at least partial failures in the past 10 months on three different rockets — the small Long March 2D, the commercial-geostationary satellite Long March 3B and the new heavy-lift Long March 5.
At the APSCC conference here on Oct. 11, China Great Wall Industry Corp. (GCWIC) Executive Vice President Fu Ziheng discussed the status the post-failure investigations.
/.../
We have confidence in Long March 5, but we know that for new launchers we may encounter problems, and unfortunately we had a failure in Long March 5.

After the failure we suspended all Long March launches, including LEO and GEO. During the past few months all the work has been done and we can say that for Long March 5 it is a problem with first-stage propulsion. Right now all the correction work is ongoing because Long March 5 is going to be used for Chinese government missions including lunar missions.
/.../
The Long March 5 first-stage propulsion problem was a design issue or a manufacturing issue?

The inquiry process is still ongoing.

ЦитироватьВ Китае завершено расследование причин неудачного полета ракеты-носителя "Чанчжэн-5 Y2"
Пекин, 16 апреля /Синьхуа/ -- Как стало известно корр. агентства Синьхуа в Государственном управлении оборонной науки, техники и промышленности в понедельник, на днях были в основном установлены причины неудачного полета ракеты-носителя "Чанчжэн-5 Y2". Были проведены многократные наземные огневые испытания усовершенствованного двигателя первой ступени ракеты-носителя, работающего на жидком водороде и жидком кислороде, которые доказали эффективность мер по улучшению двигателя.
Произведенный 2 июля 2017 года запуск ракеты-носителя "Чанчжэн-5 Y2" с космодрома Вэньчан /провинция Хайнань/ оказался неудачным. Неполадки возникли на 346 секунде полета ракеты. По итогам компьютерного моделирования и наземных испытаний были установлены причины неудачной миссии "Чанчжэн-5 Y2". Анализ полученных данных показал, что во время полета произошло изменение части структуры выхлопного устройства двигателя первой ступени ракеты-носителя, работающего на жидком водороде и жидком кислороде, в результате чего мгновенно снизилась тяга двигателя.
В настоящее время идет разработка ракеты-носителя "Чанчжэн-5 Y3", запуск которой запланирован на конец 2018 года. А в дальнейшем, с помощью ракеты-носителя "Чанчжэн-5 Y4" планируется осуществлять запуск зонда "Чанъэ-5" в рамках третьего этапа китайской программы исследования Луны.
