At 21:52 on March 30, China successfully dispatched the 17th satellite of the BeiDou satellite navigation system with the Launch No.3 C / Expedition Launch Vehicle No. 1 at Xichang Satellite Launch Center. On the early morning of the 31st, after nearly 6 hours of flight, the upper rocket stage was successfully separated from the satellites and the satellites were directly sent to work orbit. China Aerospace Science and Technology Corporation launched its first successful launch of the space launch mission. This is the first time that China has launched a medium- and high-altitude orbit satellite using the above-mentioned direct orbit technology, which means China’s real space shuttle bus
