英语新闻视频：Rocket launch a boost for California start-up

 This is Xaero - a vertical¹ take-off and landing vehicle being developed by Masten Space Systems. The California start-up hopes the rocket will eventually carry pay-loads for NASA to altitudes of up to 30 kilometres, mainly to collect atmospheric² data now unavailable to higher-flying satellites. Xaero can be flown multiple times per day. Masten says that reusable launch vehicles will ultimately make space more accessible, with more flights at lower cost. This test flight over California's Mojave Desert took Xaero to 444 metres - a record for the company. The rocket's take-off and landing technology also serves as a test-bed for space vehicles the company believes will one day be used for missions to the moon and Mars. And Masten says tests in the near future will be designed to take the rocket to its suborbital limit ...and bring it back safely to Earth Elly Park, Reuters.

参考译文: 这是Xaero，这是一架由Masten航天系统开发的垂直起飞和降落器。此次加州的初次起飞最终希望火箭能够携带NASA的装载升到30千米的高空，主要进行大气层数据收集，目前高空卫星未能获得这些数据。Xaero每天可以飞行多次。Masten称，发射器的可多次使用，以最低的花费进行更多的飞行，最终可以使太空更加触手可得。这次在加州莫哈韦沙漠上的试飞，Xaero升到444米，这是公司目前的最高记录。此次火箭的起飞和着陆技术为太空飞行器打下平台，公司相信总有一天该技术将会运用到月球和火星的任务上。Masten称，未来不久的测试将设计成携带火箭进入其亚轨道限制...并最终将其安全带回Earth Elly公园。
