主人(或許這種說法不公平)1年訂閱可用赫爾辛基-中國火箭公司空間先鋒已獲得C-round資助其Tianlong-3美軍可重複使用的運載火箭。太空先鋒,全名北京甜餅科技有限公司,有限公司,7月5日宣布一輪融資。公司的第一個看到Tianlong-2 4月發射火箭讓太空先鋒中國第一個商業機構與液體推進劑發射器到達預定軌道。該公司已經籌集了三十億元人民幣(合4.14億美元)在11輪。自2018年成立以來2月份該公司宣布,它獲得了“B +”和“Pre-C”戰略融資輪。一些主要投資者與中國政府有關。其中包括中國國際金融公司(CICC),部分國有的投資工具,建銀國際,屬於中國建設銀行公司和中信建設,中國國有的工程和建築部門中信集團和浙江大學聯創。風險資本融資也起到了很重要的作用。新基金將用於發展Tianlong-3 kerosene-liquid氧氣運載火箭及其發動機和建設一個專門在酒泉發射國家宇航中心。這筆資金還將用於開發大規模生產能力和招聘。 The first launch of the Tianlong-3 rocket is currently scheduled for May 2024 . It is intended to be somewhat comparable to the Falcon 9. If successful, Space Pioneer claims it will be able to launch 30 times per year from 2025. Tianlong-3 (“Sky Dragon-3”) is a two-stage kerosene-liquid oxygen rocket with a reusable first stage. Space Pioneer’s webpages state that the rocket will be capable of lifting 17 tons of payload to low Earth orbit, or 14 tons to 500-kilometer sun-synchronous orbit. It will have a takeoff mass of 590 tons and produce 770 tons of thrust. The 71-meter-long Tianlong-3 will have a diameter of 3.8 meters. Previously, many commercial Chinese rockets used 2.25 or 3.35-meter-diameter stages, the dimensions as those of most Long March rockets. The Tianlong-3 is, according to Space Pioneer, tailor-made for launching satellites for China’s national communications megaconstellation. Tianlong-3 will provide “important strategic support for the country’s new satellite Internet infrastructure,” according to the July 5 statement. The planned 13,000-strong Guowang constellation is seen as China’s answer to Starlink. More recently established Chinese commercial launch companies including Space Pioneer and OrienSpace are opting to develop much larger launch vehicles than earlier movers, which have committed to launchers with payload capacities on the order of a few thousand kilograms. This shift has been initiated by the emergence of the possibility of contracts for Guowang and commercial cargo missions . Space Pioneer says it has already signed 10 orders for launches on the Tianlong-2. The company also has plans for a Tianlong-3H, a triple-core version in the same style as the SpaceX Falcon Heavy, and the Tianlong-3M, a single core rocket tipped with a reusable spaceplane. Space Pioneer initially started out developing engines burning green monopropellant before changing direction. The firm also apparently scrapped development of the Tianlong-1 rocket. The firm has received sponsorship and investment from Zhangjiagang, a city in Jiangsu province on the Yangtze river. Space Pioneer is building rocket manufacturing facilities in the city and the Tianlong-2 launch also bore the name “Zhangjiagang.” Meanwhile, fellow Chinese commercial firm Landspace is gearing up for the second launch of its Zhuque-2 methane-liquid oxygen rocket from Jiuquan. Airspace closure notices indicate a launch window of 1:53 a.m. to 4:14 a.m. Eastern July 12.
