That fireball in the western sky last night was debris from a falling Russian rocket. U.S. Strategic Command spokeswoman Julie Ziegenhorn says the fireball seen over Arizona, Nevada and California in the Tuesday night sky was an SL-4 rocket body booster from Russia that was launched Monday.
People took to social media to share videos and photos and marvel at the white fireball flying through the sky that some described as a shooting star. Others wondered if it was a meteor breaking up on re-entry or space debris from a fallen satellite.
