China launched its second Kuaizhou-1A booster in four days on Sunday, orbiting a pair of commercial Ka-band satellites.
The launch of the KL-a-A and KL-a-B satellites took place from the Jiuquan Satellite Launch Center in northwest China at 6 p.m. Beijing time.
The Xinhua news agency described the payloads as “global multimedia satellites” designed to test Ka-band communication technology. The Chinese Academy of Sciences’ Innovation Academy for Microsatellites built the spacecraft, which will be used by an unidentified German company.
Kuaizhou-1A is a four-stage solid fuel booster developed by a subsidiary of the China Aerospace Science and Industry Corporation. The rocket is designed to launch micro-satellites on short notice.
China’s Kuaizhou-1A light launcher orbited two small satellites from the Jiuquan Satellite Launch Center on Friday in a successful commercial mission.
The solid-fuel booster launched DFH Satellite Company’s KX-09 microgravity experimental satellite and SpaceTY’s Xiaoxiang 1-07 CubeSat.
The Kuaizhou-1A booster is manufactured and launches are managed by Expace, which is a subsidiary of the state-owned China Aerospace Science and Industry Corporation (CASIC).
CASIS said it is planning to launch Kuaizhou-1A eight or nine more times before the end of the year. This was the booster’s first launch of 2019.
It was the fifth successful flight in five attempts for the solid-fuel Kuaizhou family of boosters, and the third success for the upgraded Kuaizhou-1A variant. The booster can place payloads weighing up to 200 kg (441 lbs) in 700 km (435 mile) high sun synchronous orbits.
Xinhuareports that a new Smart Dragon-1 booster launched three satellites into orbit from the Jiuquan Satellite Launch Center on its maiden flight.
The rocket, developed by the China Rocket Co. Ltd. affiliated to the China Academy of Launch Vehicle Technology (CALVT), blasted off from the Jiuquan Satellite Launch Center in northwest China at 12:11 p.m. (Beijing Time).
The three satellites, respectively developed by three Beijing-based companies, will be used for remote sensing services, communication and Internet of Things.
Different from the carrier rockets of the Long March family, the new Dragon series is developed in a commercial mode to meet the market demand of launching small commercial satellites, said Wang Xiaojun, head of CALVT.
The SD-1, with a total length of 19.5 meters, a diameter of 1.2 meters, and a takeoff weight of about 23.1 tonnes, is a small-scale solid-propellant carrier rocket capable of sending 200 kg payloads to the solar synchronous orbit at an altitude of 500 km.
iSpace, aka, Beijing Interstellar Glory Space Technology Ltd., has become the first private Chinese company to launch payloads into orbit.
The company launched its four-stage Hypobola-1 rocket from the Jiuquan Satellite Launch Center in the Gobi Desert on Thursday afternoon local time.
iSpace reported the rocket deployed the CAS-7B amateur radio satellite and a technology verification satellite for China Central Television. Three additional payloads remained attached to the upper stage as planned.
