The Crew-9 mission is part of NASA’s Commercial Crew Program, designed to shuttle workers to and from the International Space Station.
有趣的是,SpaceX也为其竞争对手提供发射服务。 SpaceX发射业务最大的客户是美国政府,包括NASA, Space Force, Air Force等,约有21%的发射任务涉及美国政府的载荷,包括国际空间站 (ISS) 补给任务(~9%)和国际空间站机组人员运输(~3%)。 2023年,SpaceX通过Falcon 9和Falcon Heavy共计完成了96次发射任务,并且没有...
Last year the Senate rejected a plan created by the House to implement a "Space Corps." But according to Bridenstine, Mr. Trump "doesn't want a corps, he wants a force. He talks about it as being a separate force, equal in stature than the Air Force." A "space corps," meanwhile,...

一旦卫星达到适当的高度，SpaceX就会与美国太空部队（U.S. Space Force）的第18太空控制中队进行协调。一旦协调完成，SpaceX就会启动高阻力模式，使卫星的速度降低到足以使卫星脱离轨道。在大气密度的影响下，卫星会从这个高度快速脱离轨道。在这种低空、高阻力环境中以可控的方式飞行非常困难，需要对专业卫星工程进行大量...
概括而言，差距很大，差距大其实不可怕，咱们可以努力追，毕竟咱们从一穷二白开始，这么多年已经追上不...
NASA has said its studies of the crash showed it was successful because the force of the strike changed the asteroid's orbit around a larger asteroid Didymos. NASA's measurements also found the strike reduced the orbital per...
SpaceX west coast launch facility at Vandenberg Space Force Base, during the launch of CASSIOPE, September 2013 靠近下方的位置是SpaceX的发射阵地,其他地方是军方的 这个阵地还是相当宽裕的,有两个厂房,两个发射台,其中红色地标就是猎鹰9号 猎鹰9号,清晰可见。下方有三个支架。周围确实有些乱七八糟的东西...
accelerative stress that the vehicle’s structure or payload can withstand. In manned spaceflight an acceleration about six times that of gravity is considered the maximum tolerable when thehuman bodyis positioned perpendicular to the acceleration force—i.e., with the head and heart at the same ...
