A Chinese Long March 11 rocket launched the Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) mission on Thursday.
Long March 11 lifted off from the Xichang Satellite Launch Center at 4:14 a.m. The two GECAM satellites were placed in their intended orbits, according to a press release from Long March 11’s developer, the China Academy of Launch Vehicle Technology (CALT).
The GECAM satellites, which each weigh 163 kg, are designed to detect the electromagnetic counterparts of gravitational waves. The data will aid scientists in their studies of black holes and neutron stars.
Long March 11 is now 11-for-11 since its maiden launch in September 2015. Nine flights have originated from land, the other from an ocean platform. The four-stage, solid-fuel booster can launch payloads weighing 700 kg into low Earth orbit and 500 kg into sun synchronous orbit.
The launch was the 355th launch of the Long March series of rockets.

While the United States was focused last week on its first domestic flight of astronauts to orbit in 9 years, China was busy with a pair of launches that placed four satellites into space.
A Long March 11 booster launched the Xinjishu Shiyan-G and Xinjishu Shiyan-H technology test satellites from the Xichang Satellite Launch Center on Friday, May 29.
The Xinjishu Shiyan-G satellite was developed by the Shanghai Institute of Microsatellite Innovation, which is part of the Chinese Academy of Sciences. The National University of Defence Technology developed the Xinjishu Shiyan-H satellite.
The satellites will test new Earth observation technology and inter-satellite communications.
On Sunday, a Long March 2D rocket launched the Gaofen-9 (02) remote sensing satellite from the Jiuquan Satellite Launch Center in Inner Mongolia.
The microwave spacecraft is the latest in a series of high-definition Earth observation satellites. Gaofen-9 (02) will be used for a variety of civilian purposes ranging from land use and urban planning to crop estimation and disaster prevention.
The Long March 2D booster carried the HEAD-4 technology and communications satellite as a secondary payload. The spacecraft is owned by HEAD Aerospace Tech Co. Ltd. of Beijing.
The year 2018 was the busiest one for launches in decades. There were a total of 111 completely successful launches out of 114 attempts. It was the highest total since 1990, when 124 launches were conducted.
China set a new record for launches in 2018. The nation launched 39 times with 38 successes in a year that saw a private Chinese company fail in the country’s first ever orbital launch attempt.
Already operating four spaceports (three of which drop stages over land), China will construct a new port to facilitate launches from an off-shore submersible platform, China Dailyreports.
The State-owned space conglomerate China Aerospace Science and Technology Corp is working with the eastern coastal province of Shandong to start construction of a port for sea-based space launches before the end of this year.
The Beijing-based space giant said on Tuesday that during a recent visit by Ling Wen, deputy governor of Shandong, to the company’s headquarters, a strategic cooperation framework agreement was signed by the China Academy of Launch Vehicle Technology, city government of Yantai, and Shenzhen-headquartered China International Marine Containers Group to jointly build an eastern coastal space port in Haiyang, a city administered by Yantai.
The project will make use of Yantai’s unique location, existing harbors and local space research and marine engineering facilities. Upon completion, the port will consist of support facilities for sea-based space missions and four research and production centers for carrier rockets, satellite equipment, sea-launch platforms as well as satellite data and applications.
China launched a Long March 11 from a submersible platform in June.
After a record 39 launches in 2018, China is planning to launch over 50 satellites aboard more than 30 launch vehicles this year, the China Aerospace Science and Technology Corporation (CASC) has announced.
The manifest includes the return to flight of China’s largest launch vehicle, Long March 5, after a two-year stand down. The booster, which can lift 14 metric tons to low Earth orbit (LEO), failed during its second flight on July 2, 2017 after a successful maiden flight eight months earlier.
China conducted its 39th launch of the year on Saturday with a successful flight from the Jiuquan Satellite Launch Center.
A Long March 2D rocket lifted off with the Hongyan-1 satellite aboard. It is the first spacecraft of a planned 300+ satellite constellation designed to provide global Internet service in the L- and Ka- bands.
The constellation is being developed by the China Aerospace Science and Technology Corporation (CASC).
The booster also launched six Yunhai-2 satellites that will be used to study the atmosphere.
The launch came less than a week after the China Aerospace Science and Industry Corpopration (CASIC) launched the first Hongyun-1 satellite aboard a Long March 11 booster. Hongyun-1 is the first of a planned 156-satellite constellation designed to provide global communications beginning around 2022.
China’s 39 launches was the highest number ever for the nation. The country suffered one failure when the maiden launch of Zhuque-1 booster — developed by private startup Landspace — suffered a failure of its third stage.
The United States came in second place with 34 launches in 2018.
The world’s launch providers were extremely busy in the first half of 2018, with China and the United States battling for the lead.
There with 55 orbital launches through the end of June, which amounted to a launch every 3.29 days or 79 hours. The total is more than half the 90 launches attempted in 2017. With approximately 42 missions scheduled for the last six months of the year, the total could reach 97. (more…)
The world’s launch providers have been extremely busy in the first quarter of 2018, with 31 orbital launches thus far. This is more than one third of the 90 launches conducted last year.
China leads the pack with 10 successful launches. The United States is close behind with a total of nine launches with one failure. The tenth American launch is scheduled for Monday afternoon from Florida.
In recent weeks, Chinese officials have revealed more details about the investigation into the Long March 5 launch failure last year as well as their ambitious launch plans for this year, which include a landing on the far side of the moon.
Long March 5 will be returned to flight in the second half of 2018, according to Bao Weimin, head of the Science and Technology Committee of the China Aerospace Science and Technology Corporation (CASC). Engineers have identified the cause of a launch failure that occurred last July and are working to verify it, he said.
TORONTO, Jan. 22, 2018 (Kepler Communications PR) — A new era in space communications began on Friday, January 19 with the successful launch of an ultra-low-cost telecommunications satellite from Canada-based Kepler Communications. The mission serves as a technology demonstration for Kepler’s novel Ku-band telecommunications payload, and offers the best price per MHz of any communication satellite on the market.
With this launch, the Canadian start-up becomes the first commercial company ever to launch and successfully operate a LEO communications satellite in Ku-band. This highly valuable frequency band is ideal for telecommunication services, and is currently being sought for use by many companies planning on deploying mega-constellations of satellites. Kepler’s network of satellites will eventually enable in-space connectivity for other satellites, space stations, and transport vehicles.
