德国私营火箭公司Isar Aerospace的Spectrum火箭于2025年9月5日下午4:12 EDT（挪威当地晚间10:12）从挪威北部Andøya航天中心成功发射并进入轨道2。这一成就标志着欧洲本土火箭首次成功实现轨道飞行2。
这枚高95英尺（28米）的两级火箭将5颗立方体卫星和1项科学实验送入椭圆轨道，近地点112英里（180公里），远地点311英里（500公里）2。Spectrum火箭可将约2,200磅（1,000公斤）的有效载荷运送到近地轨道2。本次发射是Spectrum的第二次飞行尝试，该公司首次发射于2025年3月进行，但任务在发射后不到1分钟因通风阀意外打开和姿态控制丧失而失败2。根据Isar Aerospace的生产计划，其制造设施每年可生产30多枚火箭2。
German aerospace company Isar Aerospace successfully launched its Spectrum rocket into orbit on September 5, 2025, marking the first time a privately developed rocket has reached orbit from European soil 2. The two-stage, 95-foot-tall (28-meter) vehicle lifted off at 4:12 p.m. EDT (10:12 p.m. local time) from the Andøya Space Center in northern Norway 2. The mission deployed five cubesats and one non-deployable science experiment into an elliptical orbit with a perigee of 112 miles (180 kilometers) and an apogee of 311 miles (500 kilometers) 2.
This successful flight represents a significant recovery for Isar Aerospace following an earlier setback 2. The company's inaugural "Going Full Spectrum" mission in March 2025 failed less than one minute after launch due to an unexpected vent valve opening and subsequent loss of attitude control 2. The Spectrum rocket is designed to carry approximately 2,200 pounds (1,000 kilograms) of payload to low Earth orbit 2, with Isar Aerospace's manufacturing facilities capable of producing over 30 rockets annually 2.
