The newest type in China's carrier rocket family – Long March 7A – made its first successful flight at the Wenchang Space Launch Center in Hainan province early Friday morning, sending a technology demonstration satellite into space.
The 60.1-meter colossal rocket blasted off from a launch pad in the coastal launch center at 1:51 am, and soon deployed the New Technology Demonstrator 9 experimental satellite into orbit, according to a statement from China Aerospace Science and Technology Corp, the nation's leading space contractor.
The mission marked the 362nd flight of the Long March rocket series and also the second by the Long March 7A. Its first flight failed in March 2020 due to malfunctions.
According to the China Academy of Launch Vehicle Technology in Beijing, the Long March 7A has a liftoff weight of 573 metric tons and a core-stage diameter of 3.35 meters. It is capable of placing a 7-ton spacecraft to geosynchronous transfer orbit.
A subsidiary of China Aerospace Science and Technology Corp, the academy is the major rocket developer in the country.

The rocket is tasked with sending satellites to high-altitude orbits such as the geosynchronous transfer and inclined geosynchronous orbits. It can also be used to carry out missions to the moon, Mars or asteroids, designers said.
A lot of China's Beidou navigation satellites and communication satellites are traveling in the geosynchronous transfer orbit.
Research and development of the new rocket took 22 months since May 2018 and were based on the Long March 7, which is tasked with sending cargo spaceships to China's future space station.
Meng Gang, Long March 7A's project manager, said the service of Long March 7A will encourage and boost the development and deployment of large, heavy satellites.

rocket系列哪個比較好看
red rocket readers比較好看。 紅火箭這本書很“重”，是一整套體系，現(xiàn)引進的書籍按照難度分為三大級別，加起來就有415本，可謂體量龐大。同時，這書也很“輕”，因為每冊書只有16頁，輕薄短小，在加拿大的學校，一節(jié)課就能完成一本，很容易實現(xiàn)單個突破。

剛才幫你查詢了一下這首歌，這首歌的名字叫做American score。
愛馬仕居然來自希臘神話，三月為什么叫March
英文的三月March一詞是來自羅馬神話中的戰(zhàn)神瑪爾斯（Mars）。今天的3月在古羅馬的歷法其實是1月，而好戰(zhàn)的古羅馬人通常在每年的這個月份出征，所以就把這個月和戰(zhàn)神瑪爾斯聯(lián)系在了一起。但是到了凱撒的時代進行了歷法改革，1月成了3月。而拉丁文代表的古羅馬文明對包括英國在內(nèi)的諸多歐洲文明產(chǎn)生巨大影響，英文的三月一詞也就由此從拉丁文的Mars演化而來。
