Kolejna awaria chińskiej rakiety 10.07. o 04:17 z Jiuquan wystrzelona została do swego pierwszego lotu RN Kuaizhou-11 (KZ-11), która miała wynieść na orbitę satelity Jilin-1 High Resolution-02E (Jilin Gaofen-02E, BiliBili VideoSat) i CentiSpace-1 S2.
W wyniku eksplozji podczas pracy trzeciego stopnia lot zakończył się niepowodzeniem.

Nieudany debiut KZ-11 BY KRZYSZTOF KANAWKA ON 11 LIPCA
(...) Rakieta KZ-11 to część rodziny chińskich rakiet KZ (Kuaizhou), z której dotychczas wystartowały najmniejsze rakiety KZ-1 i KZ-1A. KZ-11 jest nieco większą konstrukcją, zdolną do wynoszenia około 1500 kg na niską orbitę okołoziemską. Prace nad KZ-11 rozpoczęły się w 2015 roku. Rakiety rodziny KZ są oferowane przez chińską spółkę ExPace, w której udziały ma chińska rządowa spółka CASIC. (...)
Był to już szósty nieudany start rakiety orbitalnej w 2020 roku. Łącznie z tym startem dotychczas zawodziły trzy razy chińskie rakiety, raz konstrukcja amerykańska, raz konstrukcja nowozelandzko-amerykańska i raz rakieta irańska.

https://kosmonauta.net/2020/07/nieudany-debiut-kz-11/China's newest carrier rocket fails in debut missionBy Zhao Lei | chinadaily.com.cn | Updated: 2020-07-10 14:57
The debut mission of Kuaizhou 11, the newest in China's carrier rocket fleet, failed on Friday, according to its maker.
The rocket blasted off at 12:17 pm at the Jiuquan Satellite Launch Center in northwestern China's Gobi Desert to send two small satellites to two different orbits. During its flight, some abnormalities emerged and resulted in failure, China Aerospace Science and Industry Corp, one of the nation's major space contractors, said in a statement, adding that engineers are investigating the incident.
A Kuaizhou 11 is 25 meters tall, and has a diameter of 2.2 meters. With a liftoff weight of 78 metric tons, the rocket will be able to place a 1-ton payload into a sun-synchronous orbit at an altitude of 700 kilometers, according to CASIC.
Once the rocket becomes operational, it will be the most powerful solid-propellant carrier rocket in the nation. Currently, the strongest solid-propellant carrier rocket in the country is Long March 11, which has a length of 20.8 meters, a diameter of 2 meters and a liftoff weight of 58 tons.
Research and development of Kuaizhou 11 began in 2015 at China Space Sanjiang Group in Hubei province, a CASIC subsidiary specialized in solid-fuel rocket.
Designers planned to make its maiden flight in 2017 but the schedule had been repeatedly postponed due to unexpected technical difficulties, the company explained.
CASIC began to develop the Kuaizhou series in 2009 as a low-cost, quick-response product for the commercial space market. Kuaizhou is the largest solid-propellant rocket family in China, as opposed to the Long March series that mainly relies on liquid fuel.
The State-owned space conglomerate has launched 11 Kuaizhou rockets: two Kuaizhou 1s and nine Kuaizhou 1As.

Two more solid-fueled stages were expected to fire to place the mission’s two satellite payloads into orbit. Chinese officials did not say at what point in the flight the rocket malfunctioned.
“The specific cause of the failure is under further analysis and investigation,” China’s state-run Xinhua news agency said Friday.
The satellites aboard the Kuaizhou 11 rocket included a Jilin 1 Earth-imaging satellite developed by Chang Guang Satellite Technology Co. Ltd., which has launched launched 16 Jilin 1 observation satellites since 2015. The video observation spacecraft lost on Friday’s launch was developed to provide imagery to Bilibili, a Chinese video sharing website.
Bilibili said last month the satellite weighed around 379 pounds (172 kilograms).
A roughly 220-pound (100-kilogram) satellite named Centispace-1-S2 was the other payload on Friday’s mission. The satellite’s mission was not disclosed, but it follows a previous Centispace spacecraft launched in 2018 for Beijing Future Navigation Technology Co. Ltd. to augment satellite navigation services.
The Kuaizhou 11 rocket was developed by Expace, a subsidiary of the state-owned China Aerospace Science and Industry Corp., or CASIC. Expace is based in Wuhan, China, where the coronavirus pandemic emerged beginning late last year.
The first flight of the Kuaizhou 11 rocket was supposed to occur earlier this year, but the launch was delayed after a lockdown of Wuhan. (...)

(...) The debut of the Kuaizhou-11 was initially projected for 2018. Footage published by CCTV in 2019 suggested an explosive failure during first stage engine testing.
The mission was China’s 19th launch of 2020, following the successful launch of the APSTAR-6D communications satellite to geosynchronous transfer orbit Thursday.
China has suffered three failures this year. These were the debut launch of the Long March 7A in March, a new launcher which may replace the aging, hypergolic Long March 3B. The latter launcher failed in April resulting in the loss of the Indonesian Palapa-N1 communications satellite. (...)
Kuaizhou-11 and commercial launchersThe Kuaizhou-11 is a larger version of the Kuaizhou-1A solid rocket, operated by Expace, a commercial spin-off from the China Aerospace Science and Industry Corp., a state-owned missile maker. The rocket has a diameter of 2.2 meters, a mass at liftoff of 78 tons. It is capable of delivering 1,000 kilograms to a 700-kilometer Sun-synchronous orbit.
Leena Pivovarova, an analyst at consulting firm Northern Sky Research, told SpaceNews that the “KZ-11 coming online is an addition to China’s launch sector development of competitive domestic launch capabilities and service offerings to its burgeoning “commercial” space industry”.
“China’s launch sector is following a larger worldwide trend of increasing responsiveness and flexibility in launch activities, increasing its already aggressive launch cadence, to developing mobile launch operations and sea launch capabilities”, Pivovarova says.
“Cutting down traditional launch operations and gaining rapid response (or readiness) capabilities can have many advantages to both commercial and government customers. (...)
