"Spaceflight is unforgiving," NASA Administrator Jared Isaacman said in a post on X soon after the explosion, promising to "support a thorough investigation of this anomaly," which happened during a ground test and resulted in no injuries.The rocket -- which stands 98 meters (321 feet) tall and is the most powerful in Blue Origin's fleet -- exploded around 9:00 pm local time Thursday (0100 GMT Friday).It was undergoing a ground test in Cape Canaveral, Florida in preparation of an upcoming flight when it blew up in a massive fireball, sending shockwaves throughout the space industry.While anomalies during ground tests are relatively frequent, such explosions are rare, and the magnitude of the blast caused significant damage not only to the spacecraft but the launch pad itself, according to photos of the aftermath released Friday."It will take some time to rebuild their pad," Florida congressman Mike Haridopolos, whose district includes Cape Canaveral, told broadcaster Fox News on Friday.Blue Origin declined an AFP request for additional details on the incident, extent of damage or the ongoing investigation, which is conducted alongside NASA and the US Space Force.The New Glenn rocket will remain grounded while the investigation is conducted.Moon Mission
