GoKawiilBlue Origin's New Glenn rocket exploded Thursday night during a hot-fire test at a Space Force launch facility in Cape Canaveral, Florida.
Led by Amazon founder Jeff Bezos, Blue Origin is working on reusable rockets and launch services to rival those offered by Elon Musk's SpaceX. A hot-fire test is conducted on the ground with the rocket engines ignited, while the vehicle is secured to the launch pad.
Bezos said in a post on social network X that all personnel were safe following the explosion.
"All personnel are accounted for and safe. It's too early to know the root cause but we're already working to find it. Very rough day, but we'll rebuild whatever needs rebuilding and get back to flying. It's worth it."
The Brevard County Emergency Management office described the incident in a public notice as an "anomaly" which posed "no threat to the general public."
Blue Origin warned in a Friday post on X that debris from the explosion could wash ashore on some of the local beaches in the coming days or weeks.
"If you encounter any debris, do not touch or approach it for your safety," the company wrote.
Cape Canaveral Space Force Station advised that launch vehicle debris is potentially hazardous and "direct contact poses a risk to personal health and welfare," according to a statement posted to its website.
Musk also responded to the explosion on X, writing: "Most unfortunate. Rockets are hard."
The Federal Aviation Administration, which regulates commercial space activities, told CNBC in an e-mailed statement that the test was "not within the scope of FAA licensed activities," and there was "no impact to air traffic," as a result of the anomaly.
