For the fourth time in less than 10 months \u2013 and the second one to claim a successful flight \u2013 China has debuted a new small satellite launch vehicle based on solid rocket motors with a payload of less than one tonne to Low Earth Orbit. The Smart Dragon-1 (SD-1) rocket, also known by its Chinese name Jielong-1<\/em>, lifted off from the mobile launch pad at the Jiuquan Satellite Launch Center in northwestern China today at 04:11 UTC. Chinese media has later declared the launch a success.<\/p>\n

The Smart Dragon-1 (Jielong-1<\/em>) is a small solid-fueled quick-reaction launch vehicle developed by the China Academy of Launch Vehicle Technology (CALT), complementing with the larger Long March 11 that has flown seven successful flights since September 2015.<\/p>\n

Launch operations are managed by China Long March Rocket Corporation, a spin-off company of CALT. The project was formally started in February 2018, less than 18 months before today\u2019s first flight. It was designed to provide an easy to operate quick-reaction launch vehicle, that can remain in storage for long periods and to provide launch missions on short notice.<\/p>\n

According to CALT, Smart Dragon-1 can be produced from order to launch within six months and requires only a 24 hour checkout at the launch site. The whole launch vehicle is launched from a Transporter-Erector-Launcher (TEL) truck that transports the launch vehicle to the launch site.<\/p>\n

    Unusually for satellite launch vehicles, the payload volume is located between the third and fourth stages, with the fourth stage motor and all payloads installed in invert position during launch.<\/p>\n

    After separation of the third stage, the fourth stage is then flipped over for the remainder of the mission.<\/p>\n

    The vehicle has a length of 19.5 meters, 1.2 meters in diameter and a liftoff mass of about 23.1 tonnes. Smart Dragon-1 can launch a 200 kg payload to a 500 km altitude Sun-synchronous Orbit (SSO), or 150 kg to a 700 km high SSO. Two types of payload envelopes are provided: 1.1 meters diameter, 1.5 meters length or 1.4 meters diameter, 2.0 meters in length.<\/p>\n

    Smart Dragon-1 is the fourth new Chinese satellite launch vehicle to debut in the last 10 months. It follows three different launch vehicles developed by private Chinese companies:<\/p>\n

    • OneSpace\u2019s OS-M1, which failed on its first flight on March 27, 2019 due to a gyroscope problem 45 seconds after launch.<\/li>\n
    • iSpace (Beijing Interstellar Glory Space Technology Ltd.)\u2019s Hyperbola-1 (Shian Quxian-1<\/em>), which scored China\u2019s first successful launch of a fully privately funded satellite launch vehicle on July 25, 2019.<\/li>\n<\/ul>\n

      All four launch vehicles use three or four solid rocket motor stages and have a capability of several hundred kilograms to Low Earth Orbit.<\/p>\n

      Similar Chinese launch vehicles in operation include CALT\u2019s own Long March 11 (first launched in September 2015 and is capable of launching from a barge), China Aerospace Science and Industry Corporation (CASIC)\u2019s Kuaizhou-1 (first launched in September 2013; commercial variant Kuaizhou-1A in operation since January 2017) and Kaituozhe-2 also from CASIC (one successful test flight in March 2017).<\/p>\n

      The mission deployed three satellites into Low Earth Orbit.<\/p>\n

      The Jiuquan Satellite Launch Center, named after the city in Gansu Province but is actually located in Ejin-Banner, Alashan League, Inner Mongolia Autonomous Region \u2013 is China\u2019s first satellite launch center, used for the launch of China\u2019s first satellite Dongfanghong-1 on April 24, 1970.<\/p>\n

      Currently, all launch operations are located at Area 43 (also known as the South Launch Area), built for the Shenzhou human spaceflight program in the 1990s.<\/p>\n

      The area contains two fixed launch pads \u2013 Launch Pad 91 for the Long March 2F rocket for launches of the Shenzhou and Tiangong spacecraft, and Launch Pad 94 for satellite launches using the Long March 2C, 2D, 4B and 4C launch vehicles.<\/p>\n<\/p>\n
