A Blue Origin New Glenn rocket exploded on a launch pad at Cape Canaveral in Florida on Thursday night.
The space technology company, which was founded in 2000 by Amazon billionaire Jeff Bezos, said there were no injuries from the incident.
"All personnel have been accounted for. We will provide updates as we learn more," Blue Origin said in a statement. The explosion occurred during a "hotfire test", the company said, describing the incident as an "anomaly".
