Blue Origin, which is owned by Amazon founder Jeff Bezos, was gearing up for a June launch to put a batch of Amazon "Leo" internet satellites into orbit.

An unmanned Blue Origin New Glenn rocket has exploded during ‌a test launch in Florida, marking a setback for Jeff Bezos’s space venture.

In a post to social media, the company acknowledged the explosion as “an anomaly” and that “all personnel have been accounted for”.
