The successful 10-kilometer vertical takeoff and vertical landing test flight of Zhuque 3 or Rosefinch 3 VTVL-1 test rocket from the Jiuquan Satellite Launch Center in northwestern China's Gobi Desert on Wednesday marks a breakthrough in the nation's commercial space industry. 9月11日，中國自主研發的朱雀三號可重復使用試驗火箭在酒泉衛星發射中心成功完成了10公里級的垂直起降飛行測試，這標志著中國商業航天領域的一項重大突破。 This way of launching and getting back a reusable rocket involves five stages, namely ascent, engine shutdown, unpowered gliding, in-flight engine restart to control speed of descent, and, lastly, soft landing. By successfully conducting this test twice, the Zhuque 3 team has proved its ability to recycle rockets for use, thus lowering costs. 發射和回收可重復使用火箭的過程包括五個階段，分别是上升、發動機關機、無動力滑翔、空中發動機重新點火以控制下降速度，以及最后的軟著陸。朱雀3號的研發團隊已成功進行了兩次飛行測試，證明了其重復使用火箭，進而降低成本的能力。 It's tru...
