German company becomes first in Europe to launch fully commercial orbital rocket
摘要
德国初创公司Isar Aerospace于3月22日从挪威北极圈内的安岛航天中心成功发射其自主研发的“光谱”号两级火箭，将其送入近地轨道。该火箭高28米，于美国东部时间16时12分升空，约7分钟后入轨。此次发射使“光谱”号成为欧洲首枚实现入轨的全商业运载火箭，也让2018年由三名学生创立的Isar在欧洲多家竞争商业航天初创公司中脱颖而出，成为领跑者，为欧洲停
Isar Aerospace, founded in 2018 by three students at a German university, successfully launched a privately-developed rocket into low-Earth orbit Saturday from a Norwegian spaceport inside the Arctic Circle.
The two-stage rocket, named Spectrum, became the first fully commercial launch vehicle in Europe to reach orbit. With Saturday's success, Isar is the clear leader among a pack of several European launch startups vying to inject some competition into Europe's stagnant launch market.
Isar's 92-foot-tall (28-meter) Spectrum rocket lifted off at 4:12 pm EST (20:12 UTC) Saturday from Andøya Spaceport in northern Norway, where it was 10:12 pm local time as the final bluish hues of daylight faded from the late summer sky. Seven minutes later, the rocket was in orbit.
