What happened? Blue Origin rocket explosion shakes nearby homes, briefly paints the sky orange

Ground test of a crewless Blue Origin rocket in Florida led to a massive explosion overnight. Video captured fiery aftermath from miles away as the spacecraft became engulfed in flames. It was one of the largest explosions in spaceflight history and it could pose a setback for NASA's upcoming missions to the moon. ABC's Sophie Flay has the latest. It was like something out of a disaster movie. A massive fireball erupting, lighting up the night sky over Cape Canaveral, Florida. A Blue Origin rocket exploding on the launch pad. Blue Origin founder Jeff Bezos says all personnel are safe. No one was on board. The company says the rocket experienced an anomaly during an engine test for the massive 320-foot-tall New Glenn rocket, sending a massive shockwave rippling through the air. Before the explosion, two towers could be seen, one on either side of the rocket, to protect it from lightning. But now, only one tower remains. Residents in the area who've grown accustomed to space launches and failures say this one felt different. This one was more of like more of a violent shake. So we were all like, whoa, that's different. Jeff Bezos saying, 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 explosion comes just days after NASA announced a nearly $500 million contract with Blue Origin to carry out various missions to the moon. Including the deliveries of a lunar lander and lunar rovers using a New Glenn rocket. Blue Origin had emerged as really a key player in NASA's efforts to return to the moon and really compete with China in that regard. And so this is pretty devastating to that effect, and it just increases the pressure on SpaceX to perform with its Starship vehicle. It's a lot of NASA's eggs are now in just a single basket. Experts now predict delays, citing the loss of the rocket, but also the loss of the launch pad, which is the only one equipped to launch the New Glenn. It takes more than a year to build these. These are probably multi-hundred million dollar to billion dollar facilities. Sophie Flay, ABC News, New York.
