Chinese iSpace achieves orbit with historic private sector launch

HELSINKI — iSpace became the first Chinese private firm to achieve orbit with Thursday's successful launch from a national space center in the Gobi Desert.

Beijing Interstellar Glory Space Technology Ltd., also known as iSpace, launched the Hyperbola-1 launch vehicle from Jiuquan Satellite Launch Center at 1 a.m. Eastern on July 25.

The test flight carried CAS-7B, an amateur radio satellite, and a technology verification payload for China Central Television, into a 300-kilometer-altitude orbit, with three more small payloads attached to the upper stage.

The success makes iSpace the first Chinese private rocket company to achieve orbit, following failures by Landspace in October and OneSpace in March 27, both of which used solid propellant rockets. The Hyperbola-1 was earlier slated for launch in April, then early June, before slipping for unannounced reasons.

The Hyperbola-1, consisting of three solid stages with a liquid-propellant fourth stage, has a length of 20.8 meters and mass at takeoff of around 31 metric tons.

The buildup to the launch was relatively quiet. The rocket was delivered to Jiuquan in the Gobi Desert July 6, according to a social media video post from Chang'an Automobile Co., Ltd. a Chinese automobile manufacturer, which sponsored the launch through naming the launch vehicle.

iSpace, with a team of over 120 members, is one the leading NewSpace actors in China. It had already received over $100 million in Series A funding from Matrix Partners China, CDH Investments, tech giant Baidu and others, before announcing July 2 that it had secured additional A++ series round funding.

Targeting the light launch market

Chinese NewSpace startups have emerged up following a central government policy shift in late 2014 which opened the launch and small satellite sectors to private capital. Support for the sector has continued, with state and military bodies last month releasing a first set of set of rules and regulationsto guide the development of commercial launch vehicles in China.

The speed of the development of launch vehicles by private companies in China has been influenced by a civil-military integration national strategy, facilitating the transfer of restricted technologies to approved firms in order to promote innovation in dual-use technology.

Leena Pivovarova, an analyst at consulting firm Northern Sky Research, told SpaceNews that, China is growing its space program by leaps and bounds, including access to space, including through, "a unified strategy for coordinated public-private efforts to dominate space markets at large."

"We are seeing accelerated private sector development because of this integration of startups to state-owned defense contractors, who are able to offer pricing well below competition. This is largely possible because of the integrated structure of its industrial base," Pivovarova says.

The iSpace news release issued after the launch thanked the China Aerospace Science and Technology Corporation (CASC), the giant state-owned space contractor, the defense contractor China Aerospace Science and Industry Corporation, as well as state authority SASTIND, which oversees the space sector, and the Equipment Development Department of the Central Military Commission for their support.

Pivovarova notes however that current regulations restrict China's customer base, meaning its target market is mainly domestic, in addition to some customers in emerging space countries.

"Long term, China will have to somehow expand into other markets to survive."

Commercial competition intensifies

While preparations for launch were ongoing at Jiuquan, other Chinese NewSpace claimed progress. All launch vehicles sent to the launchpad by Chinese commercial companies have so far used solid propellant, many of these are working on larger, liquid propellant launchers with reusable first stages.

Landspace, another of the first wave of Chinese private launch companies along with OneSpace and Linkspace, has been making progress with development of liquid methane-liquid oxygen engines for its two-stage Zhuque-2 (Vermillion Bird-2).

In early July Landspace carried out lengthy tests of the TQ-11, a 10-ton thrust methalox engine for the Zhuque-2 second stage. This was followed with a successful 100-second test of the TQ-12 80-ton thrust methalox engine, with a measured sea-level thrust of 667 kN, above the design value of 658 kN.

Four TQ-12 engines will power the first stage of the 48.8-meter-tall, 3.35-meter-diameter Zhuque-2, for which the company says it will hold a test flight in 2020. The launcher is to be capable of delivering a 4,000-kilogram payload capacity to a 200-kilometer low Earth orbit.

iSpace is also working on a methalox launcher, and earlier in July carried out a 200-second test for its JD-1 reusable engine, which will power the first and second stages of the Hyperbola-2 rocket. The launcher will be capable of lifting 1.1 metric tons to a 500 km Sun synchronous orbit (expendable) or 700 kg reusable, with a test flight slated for 2021.

Jiuzhou Yunjian, a Beijing-based 2017 entrant into the Chinese NewSpace launch scene, has also this month tested its newly-developed 'Lingyun' 10-ton thrust methalox motor, which the company says demonstrates deep throttling and restart capabilities.

Beijing Xinghe Dongli Space Technology Co. Ltd., also known as Galactic Energy and established in February 2018 — considerably later than the first wave companies — is progressing with development of an RP-1/liquid oxygen launch vehicle named Pallas-1, which will be capable of launching four metric tons to LEO or two tons to SSO. Early July saw testing of the gas generator for the launcher's 40-tonne thrust kerolox engine, but a test launch is not expected until the end of 2022.

More immediately Galactic Energy is aiming to debut its own solid propellent 'Ceres-1' launch vehicle in March 2020, launching from Jiuquan. A main satellite and two passengers are booked for the launch, with the company advertising a remaining 79 kilograms of payload. The company will carry out ground tests across 2019 and aim to complete assembly late in the year.

China Rocket Co. Ltd., a commercial spinoff from CASC, announced July 24 that it was transporting a new, low-cost launcher to Jiuquan, thus providing further competition. The solid propellant Jielong-1 (Smart Dragon-1) is designed to be capable of putting 150 kilograms into a 700-kilometer SSO.

Китай планирует в августе запустить микроракету-носитель "Цзелун-1"
16:33

ПЕКИН, 25 июл – РИА Новости. Китай планирует в августе этого года осуществить первый запуск своей новой микроракеты-носителя "Цзелун-1", предназначенной для коммерческих миссий, говорится в сообщении Китайской корпорации космической науки и техники (CASC).

Ранее сообщалось, что запуск произведут в первой половине этого года, однако монтаж ракеты, а также все необходимые проверки и тесты завершились только к середине июля. В настоящий момент ракету наземным транспортом перевозят с завода на космодром Цзюцюань в китайской северо-западной провинции Ганьсу, откуда и планируется произвести запуск.

В августе 2018 года CASC представила проект своей новой микроракеты-носителя "Цзелун-1". Сообщалось, что ракета станет первой в серии малогабаритных ракет-носителей "Цзелун" и будет способна нести до 150 килограммов полезного груза на солнечно-синхронную орбиту высотой 700 километров. Разработкой и строительством ракеты-носителя занималась компания Chinarocket Co. при CASC.

Несмотря на свои небольшие размеры, твердотопливная ракета "Цзелун-1" сможет работать по программе запусков "одна ракета — один спутник" и "одна ракета — много спутников", то есть нести на орбиту сразу несколько космических аппаратов. Общая длина ракеты составляет 19,5 метров, диаметр – 1,2 метра, стартовый вес - 23,1 тонны.

Ожидается, что стоимость новой китайской ракеты будет ниже представленных на международном рынке аналогов. Производственный цикл данного типа ракет занимает около 6 месяцев, а подготовка ракеты к миссии потребует не более 24 часов.

Chinese Long March launch tests grid fins for safely, future reusability
by Andrew Jones — July 30, 2019

HELSINKI — Launch of a Long March 2C from Xichang last week included a first use of grid fins by China to minimize the threat posed by the spent first stage to populated areas downrange.

The two-stage hypergolic Long March 2C lifted off at 11:57 p.m. Eastern July 25 carrying three Yaogan-30 (group 5) satellites into a roughly 600 kilometer orbit inclined by 35 degrees. With few details available, outside observers state that the satellites are likely for reconnaissance use by the People's Liberation Army.

Gaining more attention was the fact that the interstage section of the launch vehicle, colored gray above and attached to the first stage, included four grid fins with apparent resemblance to those used to guide SpaceX Falcon 9 and Falcon Heavy boosters back to landing areas.

The China Aerospace Science and Technology Corporation (CASC), the main contractor for China's space programs, stated in a post-launch statement that the stage fell within the designated zone in prefectures within Guizhou province. Footage of first stage falling to Earth in a densely vegetated area was also released on social media.

The test comes in apparent response to increased awareness and visibility of spent boosters falling downrange near populated areas and increased launch activity. Three of China's four national launch centers were established during the Cold War, with tensions with the United States and Soviet Union prompting the decision for the sites to be located far inland for security reasons. Despite careful rocket flight path design and safety measures on the ground, spent boosters have frequently fallen among towns and villages downrange from Xichang, sometimes damaging property.

According to CASC, a team of one dozen members with an average age of under 35 carried out the research and development of the grid fins, which needed to be able to unlock, extend and rotate while also resisting high temperatures and pressures.

CASC stated that the grid fins successfully helped ease safety concerns by allowing a hard landing within a smaller drop zone, reducing both the need for evacuation of populated areas and hence inconvenience to locals and launch costs.

Additionally CASC states that the breakthrough is of major significance to Chinese aerospace and is a step toward controlled descent and landings which could lead to reuse of rocket stages.

The China Academy of Launch Vehicle Technology (CALT) and the Shanghai Academy of Space Technology (SAST), two rocket design and manufacturer groups belonging to CASC, are developing launch vehicles capable of vertical takeoff and vertical landing, including the new Long March 8 and a variant of the Long March 6, both using kerosene and liquid oxygen.
 

Long March 5 update

A Chinese language article published by China Youth Daily has obliquely referred to a delay to the third flight of the Long March 5, China's only heavy-lift rocket and a requirement for major planned missions. As SpaceNews reported in June, preparations for a stated return to flight late July had not taken place, indicating a slip in the schedule.

The July 26 article states that a redesign of the turbopump for the YF-77 liquid hydrogen-liquid oxygen propellant engines has taken place, adding five guide vanes to the exhaust structure. The YF-77 was isolated as the point of failure at 346 seconds into the second flight of the Long March 5 in July 2017.

The 'substantial' redesign has led to the scrapping of existing inventories. The production of the new components, using nickel superalloys instead of stainless steel used previously, is imminent, according to the article.

No indication of a revised launch schedule for the Long March 5 or the test flight of the Long March 5B variant for low Earth orbit launches was given.

Transfer of rocket components from the northern port city of Tianjin to the southern island of Hainan and subsequent launch preparations at Wenchang Satellite Launch Center have previously taken two-and-a-half months, meaning a return to flight of the Long March 5 no earlier than late 2019. This may result in a compression of the launch schedule or a prioritizing of missions.

Based on a successful return to flight in July, the fourth Long March 5 was slated to launch the Chang'e-5 lunar sample return mission at the end of 2019. A test launch of the Long March 5B, the launcher designed for the construction of the future Chinese Space Station, would then follow, before the fifth Long March 5 launches the country's first independent mission to Mars during a once-every-26-month launch window in late July to early August 2020.

Китай на параде продемонстрировал новейшие ракеты
01.10.2019 12:53:27

Пекин. 1 октября. ИНТЕРФАКС - Китай в ходе парада, посвященного 70-й годовщине образования КНР, показал ракеты нового типа, сообщает в понедельник агентство Associated Press.

В частности, впервые была продемонстрирована баллистическая ракета средней дальности Дунфэн-17 (DF-17). Эта ракета способна развивать скорость в пять раз выше скорости звука, заявляют эксперты. Такая скорость, а также то, что в ней используется разделяющаяся головная часть с блоками индивидуального наведения, технология, позволяющая поразить несколько целей при запуске одной ракеты, делает сложным ее отслеживание и перехват, отмечает AP.

На параде также можно было увидеть межконтинентальную баллистическую ракету Дунфэн-41 (DF-41). Эта ракета способна достичь территории США за 30 минут, пишет Associated Press. До сих пор китайские военные не показывали ее на парадах.

Кроме того, на параде показали баллистическую ракету для подлодок Цзюйлан-2 (JL-2). Считается, что такие ракеты размещаются на китайских атомных подводных лодках класса "Цзинь", пишет АР. Эти ракеты Китай также демонстрирует впервые.

Еще одним дебютом на параде стали сверхзвуковые крылатые ракеты CJ-100. Это ракеты большой дальности с высокой точностью, сообщают китайские СМИ. Они предположительно заменят крылатые ракеты наземного базирования CJ-10.

Помимо прочего, зрители парада смогли увидеть обновленные ракеты Дунфэн-31. Это твердотопливные ракеты, отличающиеся высокой точностью, сообщают китайские СМИ.

Еще одним новшеством стал беспилотник "Острый меч", который, как полагают эксперты, способен атаковать военные базы и радиолокационные базы.

В Пекине во вторник проходят торжества по случаю 70-й годовщины образования Китайской Народной Республики. В Пекине состоялся военный парад, в котором приняли участие 15 тыс. военнослужащих Народно-освободительной армии Китая.

Учитывая, что два дня назад китайские эсминцы взяли "в коробочку" американский авианосец в Южно-Китайском море, это как бы намекает.
